Summary Risk Factors
Risks related to our financial position and capital needs
|●||We anticipate incurring substantial operating losses for the foreseeable future and may never achieve or maintain profitability.|
|●||Adverse developments affecting financial institutions, companies in the financial services industry or the financial services industry generally, such as actual events or concerns involving bank failures, liquidity, defaults or non-performance, could adversely affect our operations and liquidity.|
|●||We have a limited operating history, which makes it difficult to assess our future viability.|
|●||We will require substantial additional funding to finance our operations to complete the development and commence commercialization of our product candidates.|
Risks related to the development and commercialization of our product candidates
|●||Our product candidates, Gammabody™ platform and related technologies are novel approaches to cancer treatment, which makes it difficult to predict the time and cost of development and subsequent regulatory approval.|
|●||We are dependent on the successful clinical development, regulatory approval and commercialization of our product candidates. Our product candidates could fail to demonstrate safety and efficacy at any stage of development, which could prevent or delay us from obtaining required regulatory approvals and commercializing our product candidates.|
|●||Success in preclinical studies or early-stage clinical trials may not be indicative of results in future clinical trials.|
|●||We have in the past, and in the future may enter into collaborations with third parties to conduct, supervise and monitor our preclinical studies and clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business and delay or impair our ability to obtain regulatory approval or otherwise commercialize our product candidates.|
|●||If we encounter difficulties in enrolling, qualifying or retaining patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.|
|●||Serious adverse events or undesirable or unexpected side effects of our product candidates may be identified during development or after approval, which could lead to the discontinuation of our clinical development programs, refusal by regulatory authorities to approve our product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product candidates thereby limiting the commercial potential of such product candidate.|
|●||Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data becomes available and are subject to audit and verification procedures that could result in material changes in the final data.|
|●||We face significant competition, and many of our competitors have substantially greater experience and resources than we have.|
Risks related to manufacturing and reliance on third parties
|●||The manufacture of biotechnology products is complex, and manufacturers often encounter difficulties in production, which could negatively affect our ability to develop or commercialize our product candidates.|
|●||To date, we have relied on a single-source supplier for bulk drug substance and drug manufacturing for certain of our product candidates. The loss of this supplier or its failure to supply us with bulk drug substance on a timely basis for such product candidate could impair our ability to develop our product candidate or otherwise delay the development process, which could adversely affect our business.|
|●||We are dependent on third-party service providers to perform critical activities related to the research, development and manufacturing of our product candidates. If these third-party service providers fail to perform, our development program could be delayed with materially adverse effects on our business, financial condition, results of operations and prospects.|
Risks related to our intellectual property
|●||If we are unable to obtain and maintain patent and other intellectual property protection for our product candidates and technology, or if the scope of protection obtained is not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability to successfully commercialize our product candidates and technology may be adversely affected.|
|●||Obtaining and maintaining our patent rights depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies and we may be unsuccessful in complying with such requirements.|
|●||Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.|
|●||Even if we are successful in obtaining and maintaining robust intellectual property rights, such protections do not necessarily address all potential threats to the competitive advantages maintained by our business.|
Risks related to our business operations, employee matters and managing growth
|●||Our business and operations may be adversely affected by economic downturns, inflation, increases in interest rates, natural disasters, public health crises, political crises, geopolitical events, such as the crisis in Ukraine or other macroeconomic conditions, which could negatively impact our business and financial performance.|
|●||If our collaboration agreement with Seagen Inc. (Seagen) is terminated or if Seagen materially breaches its obligations thereunder, or it the collaboration does not progress due to manufacturing issues, clinical trial results or for other reasons, our reputation could be impacted or business, prospects, operating results, and financial conditions could be materially harmed.|
|●||We may expand our organization, and we may experience difficulties in managing this growth.|
|●||There are risks inherent in our business that may subject us to potential product liability suits and other claims.|
|●||If the security of the personal information that we collect, store or process is compromised, we may be exposed to liability and loss of business.|
|●||We may be classified as a passive foreign investment company (PFIC) for United States (U.S.) federal income tax purposes, which could result in adverse U.S. federal income tax consequences to U.S. investors in the common shares.|
Risks related to regulatory compliance
|●||The regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the clinical development and regulatory approval of our product candidates.|
|●||Even if a product candidate receives marketing approval, it may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community.|
Risks related to ownership of our common shares
|●||The market price of our common shares has been and may continue to be volatile.|
|●||Shareholders may not be able to exercise pre-emption rights and, as a result, may experience substantial dilution upon future issuances of common shares.|
|●||We have identified material weaknesses in our internal control over financial reporting.|
Risks related to our financial position and capital needs
We are a clinical-stage immuno-oncology company and have incurred significant operating losses since inception. We anticipate that we will continue to incur substantial operating losses for the foreseeable future and may never achieve or maintain profitability.
We are a clinical-stage immuno-oncology company and have incurred significant operating losses since inception. Our net loss was $31.9 million and $42.4 million for the years ended December 31, 2022, and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $108.1 million. To date, we have recognized minimal license revenues with no significant milestone revenues expected to be recognized over the next 12 months, and we have not recorded any revenues from product sales. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future.
Since inception, we have devoted substantially all of our efforts to preclinical and clinical research and development of our product candidates and technology, organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio and conducting clinical trials. We have not obtained regulatory approval for, or commercialized, any product candidates and it could be several years, if ever, before we have a commercialized product. The net losses we incur may fluctuate
significantly from quarter to quarter and year to year. We anticipate that our expenses will increase substantially if, and as, we:
|●||continue the ongoing and planned development of our product candidates, including LAVA-051 and LAVA-1207 and other early-stage product candidates;|
|●||initiate, conduct and complete any ongoing, anticipated or future preclinical studies and clinical trials for our current and future product candidates;|
|●||develop processes and scale manufacturing production for our current and future product candidates in accordance with current Good Manufacturing Practices (cGMP);|
|●||seek regulatory and marketing approvals for LAVA-051, LAVA-1207 and any of our other product candidates that successfully complete clinical trials;|
|●||discover and develop additional bispecific gamma delta engagers and make further investments in our Gammabody platform to identify additional product candidates;|
|●||maintain, protect and expand our intellectual property portfolio, including incurring costs associated with opposing and invalidating competitor patents and licensing other technologies for our product candidates;|
|●||establish a sales, marketing, manufacturing and distribution, supply chain and other commercial infrastructure in the future to commercialize any current or future product candidate for which we may obtain marketing approval;|
|●||expand our operations in the U.S. and Europe;|
|●||add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts;|
|●||acquire or in-license additional product candidates and technologies;|
|●||develop a potential companion diagnostic;|
|●||address any events outside of our control, including, but not limited to, outbreaks of infectious diseases such as the COVID-19 pandemic; and|
|●||general economic and market conditions and overall fluctuations in the United States and international equity markets, such as deteriorating conditions due to investor concerns regarding inflation and the hostilities between Russia and Ukraine.|
To become and remain profitable, we must succeed in developing and eventually commercializing products that generate significant revenue. We may however never succeed in generating significant revenue and, even if we do, may never generate revenues that are sufficient to offset our expenses and achieve profitability.
Because of the numerous risks and uncertainties associated with product candidate development, we are unable to accurately predict the timing or amount of expenses or when, or if, we will be able to achieve profitability. If we are required by regulatory authorities to perform clinical trials or preclinical studies in addition to those currently expected, or if there are any delays in the initiation and completion of our clinical trials or the development of any of our product candidates, our expenses could increase.
Moreover, even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, maintain our research and development efforts, and expand our business or continue our operations.
Adverse developments affecting financial institutions, companies in the financial services industry or the financial services industry generally, such as actual events or concerns involving bank failures, liquidity, defaults or non-performance, could adversely affect our operations and liquidity.
Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank, or SVB, was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation, or the FDIC, as receiver.
Although a statement by the U.S. Department of the Treasury, the Federal Reserve and the FDIC stated that all depositors of SVB would have access to all of their money on the business day following the date of closure, uncertainty and liquidity concerns in the broader financial services industry remain, as other financial institutions face similar threats. Inflation and rapid increases in interest rates have led to a decline in the trading value of previously issued government securities with interest rates below current market interest rates. The U.S. Department of Treasury, FDIC and Federal Reserve Board have announced a program to provide up to $25 billion of loans to financial institutions secured by such government securities held by financial institutions to mitigate the risk of potential losses on the sale of such instruments. However, widespread demands for customer withdrawals or other needs of financial institutions for immediate liquidity may exceed the capacity of such program. There is no guarantee that the U.S. Department of Treasury, FDIC and Federal Reserve Board will provide access to uninsured funds in the future in the event of the closure of other banks or financial institutions in a timely fashion or at all.
Our access to our cash and cash equivalents in amounts adequate to finance our operations could be significantly impaired by the financial institutions with which we have arrangements directly facing liquidity constraints or failures. In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs of capital and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and cash equivalents could adversely impact our ability to meet our operating expenses, result in breaches of our contractual obligations or result in violations of federal or state wage and hour laws. Any of these impacts could have material adverse impacts on our operations and liquidity.
Our cash and cash equivalents may be exposed to the risk of loss as a result of the failure of our banking institutions with which we have a banking relationship.
While we seek to minimize our exposure to third-party losses of our cash and cash equivalents, we hold our balances in a number of large financial institutions. Notwithstanding, those institutions are subject to risk of failure. For example, on March 10, 2023, SVB was unable to continue its operations and the FDIC was appointed as receiver to hold its deposits. On March 26, 2023, First–Citizens Bank & Trust Company, Raleigh, North Carolina (“First Citizens”) purchased all deposits and loans of SVB, and depositors of SVB became depositors of First Citizens.
As of March 31, 2023, less than $0.1 million of our cash and cash equivalents were held with First Citizens. All of our other cash and cash equivalents are held with other large financial institutions, and we do not expect further developments with the purchase of SVB’s deposits by First Citizens to have a material impact on our cash and cash equivalents balance, expected results of operations, or financial performance for the foreseeable future. However, if further failures occur at financial institutions where we hold deposits, we could experience additional risk of loss of our cash and cash equivalents. Any such loss or limitation on our cash and cash equivalents would adversely affect our business.
Our limited operating history may make it difficult to evaluate the success of our business to date and to assess our future viability.
Since inception, our operations to date have been limited to developing our Gammabody platform, financing and staffing our company, identifying and developing LAVA-051, LAVA-1207 and other product candidates, business planning and providing general and administrative support to these operations. Our product candidate, LAVA-051, is being evaluated in a Phase 1/2a clinical trial in chronic lymphocytic leukemia (CLL), multiple myeloma (MM) and, at later stages, acute myeloid leukemia (AML). Our solid tumor product candidate, LAVA-1207, is being evaluated in a Phase 1/2a clinical trial in metastatic castration-resistant prostate cancer (mCRPC). We have not yet, and may never, successfully complete a clinical trial, obtain marketing approval, manufacture commercial scale cGMP-product (including through a third party), or conduct sales and marketing activities necessary for successful product commercialization. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing product candidates.
In addition, as a business with a limited operating history, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will eventually need to transition from a company with a research and clinical focus to a company capable of supporting commercial activities, if any of our product candidates are approved. We may not be successful in such a transition.
We will require substantial additional funding to finance our operations to complete the development and commence commercialization of our product candidates. If we are unable to raise capital when needed, we could be forced to delay, reduce or terminate certain of our development programs or other operations.
We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the Phase 1/2a clinical trials for LAVA-051 and LAVA-1207, initiate later-stage clinical development, and continue to research, develop and initiate clinical trials for other product candidates and obtain and maintain intellectual property and other proprietary rights. In addition, if we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution, as well as expenses related to any milestone and royalty payment.
Furthermore, our operations have consumed substantial amounts of cash since inception, and we expect our expenses to continue to increase in connection with the costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations and planned research and clinical development activities. Because the design and outcome of our ongoing and anticipated clinical trials are highly uncertain, we cannot reasonably estimate the actual amount of resources and funding that will be necessary to successfully complete the development and commercialization of any product candidate we develop. Although it is difficult to forecast all of our future liquidity requirements, based on our current research and development plans, we believe that our existing cash, cash equivalents and investments will be sufficient to fund our operations through at least the next 12 months. Moreover, we will need to obtain substantial additional funding in connection with our continuing operations and planned research and clinical development activities.
Until we can generate sufficient product revenue to finance our cash requirements, which we may never do, we expect to finance our future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. Disruptions in the financial markets and other global events may make equity and debt financing more difficult to obtain and may have a material adverse effect on our ability to meet our fundraising needs. If we are unable to obtain sufficient funding in a timely manner or on commercially acceptable terms, we may have to delay, reduce the scope of, or eliminate one or more of our development programs, and consider other cost reduction initiatives, such as downsizing our operations or suspending, curtailing, or withholding initiation or expansion of clinical trials or research. In addition, in the event we are not able to generate sufficient funds, we may be unable to continue as a going concern and our business, financial condition and/or results of operations could be materially and adversely affected which could result in a decrease in the price of our common shares and, ultimately, insolvency. In addition, any perceived or actual
inability by us to finance our clinical development activities and other business activities may cause the market price of our common shares to decline.
We will need to raise additional capital, which may not be available on acceptable terms, or at all. Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our product candidates.
Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through public or private equity or debt financings, third-party funding, marketing and distribution arrangements, as well as other collaborations, strategic alliances and licensing arrangements, or any combination of these approaches. We do not have any committed external source of funds. To the extent that we raise additional capital, if available, through the sale of equity or convertible debt securities, your ownership interest in our company may be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt and equity financings, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as redeeming our shares, making investments, incurring additional debt, making capital expenditures, declaring dividends or placing limitations on our ability to acquire, sell or license intellectual property rights. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our common shares to decline and existing shareholders may not agree with our financing plans or the terms of such financings. Adequate additional financing may not be available to us on acceptable terms, or at all.
If we raise additional capital through future collaborations, strategic alliances or third-party licensing arrangements, we may have to relinquish valuable rights to our intellectual property, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us, if at all. If we are unable to raise additional capital when needed, we may be required to delay, limit, reduce or terminate our product candidate development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise develop and market ourselves.
Exchange rate fluctuations could negatively affect our financial condition.
Our consolidated financial statements are presented in U.S. dollars (USD). We operate via our Dutch and U.S. entities, but we also conduct business in Switzerland, Spain, Italy and France. Therefore, we have expenses denominated in USD, euros and Swiss francs in connection with, among other things, our sponsored clinical trials, purchase of drug product for our clinical trials, process development and the prosecution and maintenance of our intellectual property portfolio. As a result, our business and share price may be affected by fluctuations between the euro, the USD and the Swiss franc, which may have a significant impact on our reported results of operations and cash flows from period to period.
Risks related to the development and commercialization of our product candidates
Our product candidates and related technologies, including LAVA-051 and LAVA-1207, which are based on bispecific gamma delta T cell engagers, are novel approaches to cancer treatment, which makes it difficult to predict the time and cost of development and subsequent regulatory approval. Currently, there are no bispecific gamma delta T cell engagers which have been approved for cancer treatment by the United States Food and Drug Administration (FDA) or European Medicines Agency (EMA).
We have concentrated our product candidates and research and development efforts on our Gammabody platform, which we believe represents a novel approach to cancer treatment. Our future success depends on our successful development of our bispecific gamma delta T cell engager product candidates and related technology.
To date, gamma delta T cells and products that induce gamma delta T cell activation have only been evaluated in a limited number of early clinical trials. These clinical trials were primarily designed to evaluate safety and tolerability, and not designed to produce statistically significant results as to efficacy. Although prior clinical trials by other companies have shown early signs of gamma delta T cell efficacy, and other
clinical trials have produced encouraging results regarding bispecifics, our Phase 1/2a clinical trials for LAVA-051 and LAVA-1207 are the only clinical trials conducted that utilize our Gammabody technology. Even after the completion of our Phase 1/2a clinical trials for LAVA-051 and LAVA-1207, our Gammabody product candidates will have only been tested in a small number of patients. Results from these clinical trials may not necessarily be indicative of the safety and tolerability or efficacy of our product candidates as we expand into larger clinical trials.
There can be no assurance that we will not experience problems or delays in developing LAVA-051, LAVA-1207 and additional product candidates, in particular, as a result of the limited number of prior studies and clinical trials of gamma delta T cells, and that such problems or delays will not cause unanticipated costs, or that such development problems can be solved. Our Gammabody platform and our LAVA-051 and LAVA-1207 product candidates are in early stages of development and may never be commercialized. Although we intend to leverage our experience with LAVA-051 and LAVA-1207 in our preclinical and clinical development of other product candidates, we may be unable to reduce development timelines or costs for our other Gammabody programs. For instance, we may encounter unforeseen problems and delays for current and future product candidates that are either or both specific to a product candidate or extend to multiple product candidates.
We may not ultimately be able to provide the regulatory authorities with clinical evidence to support a claim of safety, efficacy, purity, and potency sufficient to approve our Gammabody product candidates for any indication. This may occur for reasons such as early clinical trials do not meet their endpoints, later clinical trials fail to reproduce favorable data obtained in earlier clinical trials, the results of such trials are not statistically significant, or the FDA, EMA or other regulatory body disagrees with how we interpret the data from these clinical trials, or does not accept these therapeutic effects as valid endpoints in pivotal clinical trials necessary for market approval. Moreover, we will also need to demonstrate that our product candidates are safe. We have only recently begun to receive safety data on our clinical trials. We do not have data on possible harmful long-term effects of our Gammabody product candidates and do not expect to have this data in the near future. As a result, our ability to generate clinical safety and efficacy data sufficient to support submission of a marketing application or commercialization of our Gammabody product candidates is subject to significant uncertainty and risk.
Furthermore, actual or perceived safety issues, including adoption of new therapeutics or novel approaches to treatment, may adversely influence the willingness of patients to participate in clinical trials, or if approved by applicable regulatory authorities, of physicians to subscribe to the novel treatment mechanics.
In particular, T cell engagers developed by other companies have been observed to cause safety issues, including cytokine release syndrome (CRS), which have, in certain cases, resulted in a delay or abandonment of those clinical programs. At present, only a few bispecific T cell engagers, including blinatumomab, are approved by the FDA. Our Gammabody class of bispecific gamma delta T cell engager product candidates have been perceived as potentially having similar complications. These perceived complications have affected the clinical protocol design of our clinical trials in the United States and may have further impact in other jurisdictions. Because all our product candidates are based on the same core Gammabody platform, if any of our product candidates encounter safety or efficacy problems, developmental delays or regulatory issues or other problems, these could impact the development plans for our other product candidates.
Also, competitors who are developing other bispecific gamma delta T cell engagers may experience problems with their product candidates that could identify problems with T cell engagers generally, which could potentially harm our ability to develop and commercialize our product candidates and harm our business. Our class of bispecific gamma delta T cell engagers could have, or be perceived to have, additional complications due to their unique mechanism of action (MoA). Consequently, we cannot be certain that our product candidates will be successful in clinical studies or that they will receive regulatory approval even if they are successful in clinical studies. If our product candidates face such complications or other challenges that we are unable to satisfactorily resolve, our ability to commercialize and generate product revenue will be significantly and adversely affected.
We are dependent on the successful clinical development and regulatory approval of our product candidates. We cannot give any assurance that LAVA-051, LAVA-1207 or any of our future product candidates will receive regulatory approval, and if we are not able to obtain required regulatory approvals, we will not be able to commercialize our product candidates, which will adversely affect our ability to generate product revenue.
We are in early-stage clinical development with two product candidates, LAVA-051 and LAVA-1207. Our business is dependent on our ability to successfully complete development of, and obtain regulatory approval for, our product candidates in a timely manner. We may face unforeseen challenges in our product candidate development strategy, and we can provide no assurances that (i) our product candidates will prove to be effective, (ii) we will be able to take advantage of abbreviated regulatory pathways for any of our product candidates or (iii) we will ultimately be successful in our ongoing and future clinical trials.
Our ability to generate product revenues, which we do not expect to occur for several years, if ever, will depend on the successful development and eventual commercialization of the product candidates we develop, which may never occur. All of our product candidates, and any future product candidates we develop, will require additional preclinical and clinical development, management of clinical, preclinical and manufacturing activities, marketing approval in the United States and other jurisdictions, demonstrating cost effectiveness to pricing and reimbursement authorities in various jurisdictions, obtaining and securing sufficient manufacturing supply for both clinical development and commercial production, building of a commercial organization, and substantial investment and significant marketing efforts before we generate any revenues from any future product sales.
Our ability to successfully complete clinical development and obtain regulatory approval from the FDA, EMA or comparable regulatory authority for our product candidates will depend on several factors, including the following:
|●||successful and timely completion of our current clinical trials;|
|●||initiation and successful patient enrollment and completion of additional clinical trials on a timely basis;|
|●||receipt of safety, tolerability and efficacy profiles that are satisfactory to the FDA, EMA or any comparable regulatory authority for marketing approval;|
|●||agreement by regulatory authorities with our interpretation of data from our preclinical studies or clinical trials;|
|●||the adequacy of record keeping or the record keeping of our clinical trial sites or investigators;|
|●||approval by regulatory authorities of our manufacturing processes or facilities of third-party manufacturers with whom we contract for clinical and commercial supplies or our own manufacturing facility;|
|●||timely receipt of marketing approvals for our lead product candidates from applicable regulatory authorities;|
|●||the performance of our current and future collaborators; and|
|●||the extent of any required post-marketing approval commitments to applicable regulatory authorities.|
We do not have control over these factors and any of them could impact or prevent our ability to obtain regulatory approval, in which event, our business will be harmed.
Additionally, our current Phase 1/2a clinical trials for LAVA-051 and LAVA-1207 involve studying a relatively small patient population, which makes it difficult to predict whether the results observed in such clinical trials will be repeated in larger and more advanced clinical trials. We may experience numerous unforeseen events prior to, during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including the following:
|●||delays in reaching a consensus with regulatory authorities on the design, location or implementation of our clinical trials for LAVA-051 and LAVA-1207 and other potential product candidates;|
|●||delays or setbacks in patient identification, qualification and enrollment;|
|●||clinical trials of our product candidates may produce negative or inconclusive results;|
|●||redesigning our study protocols and need to conduct additional studies as may be required by a regulator;|
|●||changes in regulation or policy relating to the development and commercialization of our product candidate by the FDA, EMA or other comparable foreign regulatory authorities|
|●||delay or failure in obtaining the necessary approvals from regulators or institutional review boards (IRBs), in order to commence a clinical trial at a prospective trial site, or their suspension or termination of a clinical trial once commenced;|
|●||the number of patients required for clinical trials for our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or may be lower than we anticipate due to challenges in recruiting, qualifying and enrolling suitable patients that meet the study criteria, participants may drop out of these clinical trials at a higher rate than we anticipate or the duration of these clinical trials may be longer than we anticipate;|
|●||imposition of a clinical hold by regulatory authorities as a result of, among other reasons, a serious adverse event or a failed inspection of our clinical trial operations, trial sites or manufacturing facilities;|
|●||occurrence of serious adverse events associated with the product candidate that are viewed to outweigh its potential benefits; and|
|●||need to conduct additional clinical trials or abandon product development programs.|
Furthermore, any inability to successfully complete preclinical and clinical development could result in additional costs or impair our ability to generate revenue from future product sales or other sources. In addition, if we make manufacturing or formulation changes to our product candidates, we may need to conduct additional testing to bridge our modified product candidate to earlier versions. Clinical trial delays could also shorten any periods during which we may have the exclusive right to commercialize our product candidates, if approved, or allow our competitors to bring competing products to market before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business, financial condition, results of operations and prospects.
Success in preclinical studies or early-stage clinical trials may not be indicative of results in future clinical trials.
Results from preclinical studies or early-stage clinical trials are not necessarily predictive of future clinical trial results, and interim results of a clinical trial are not necessarily indicative of final results. Our product candidates, LAVA-051 and LAVA-1207, are still in the early stages of development in Phase 1/2a clinical trials. Our product candidates may fail to show the desired safety and efficacy in clinical development despite demonstrating positive results in preclinical studies or having successfully advanced through initial clinical trials.
Furthermore, we have limited safety and clinical efficacy data for the use of LAVA-051 and LAVA-1207 in humans. There can be no assurance that the results seen in preclinical studies for any of our product candidates ultimately will result in success in clinical trials. In addition, there can be no assurance that we will be able to achieve the same or similar success in our preclinical studies and clinical trials of our other product candidates.
There is a high failure rate for drugs and biologic products proceeding through clinical trials. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving promising results in preclinical testing and earlier-stage clinical trials. The design of a clinical trial may also affect its ability to support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. As an organization, we have limited experience designing clinical trials and may be unable to design and execute a clinical trial to support regulatory approval.
If we do not observe favorable results in the clinical trials of our product candidates that would support regulatory approval, we may decide to delay or abandon clinical development of such product candidates. Similarly, data obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit or prevent regulatory approval. In addition, we may experience regulatory delays or rejections as a result of many factors, including due to changes in regulatory policy during the period of our product candidate development. Any such delays could materially and adversely affect our business, financial condition, results of operations and prospects.
We have in the past, and in the future may enter into collaborations with third parties to conduct, supervise and monitor our preclinical studies and clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business and delay or impair our ability to obtain regulatory approval or otherwise commercialize our product candidates.
We rely upon, and intend to rely on for the foreseeable future, clinical research organizations (CROs) and academic institutions to monitor and manage data for our preclinical programs and ongoing clinical programs, including our clinical trials for LAVA-051 and LAVA-1207. We control only certain aspects of the activities of our third-party service providers, including investigators and CROs. Nevertheless, we will be responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on third parties does not relieve us of our regulatory responsibilities.
We and these CROs are required to comply with good clinical practices (GCPs) which are regulations and guidelines enforced by the FDA and comparable regulatory authorities for any of our product candidates that are in preclinical and clinical development. The regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. Although we rely on CROs to conduct GCP-compliant clinical trials, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with its investigational plan and protocol and applicable laws and regulations. If we or our CROs fail to comply with GCPs, the clinical data generated in our clinical trials may be deemed unreliable, and the FDA or comparable regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. If our CROs fail to comply with these regulations or fail to recruit a sufficient number of subjects, we may be required to repeat clinical trials, which would delay the regulatory approval process.
Further, these investigators, academic institutions and CROs are not our employees, and we will not be able to control, other than by contract, the number of resources, including time, which they devote to our product candidates and clinical trials. Use of third-party service providers may require us to disclose our proprietary or confidential information to these parties, which could increase the risk that this information will be misappropriated.
Our reliance on third parties to conduct clinical trials will result in less direct control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with CROs and other third parties can be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Such parties may:
|●||have staffing difficulties or experience management or ownership changes;|
|●||fail to comply with contractual obligations, including with respect to confidentiality;|
|●||experience regulatory compliance issues;|
|●||undergo changes in priorities; or|
|●||become financially distressed.|
These factors may adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject us to unexpected cost increases that are beyond our control. If our CROs, or hospitals where we conduct our clinical trials, do not successfully carry out their contractual duties or obligations with us or regulatory agencies, fail to meet necessary safety measures and protocols or meet expected deadlines, or fail to comply with regulatory and/or independent institutional review board (IRB) requirements, or if the quality or
accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize, any product candidate that we develop. Consequently, our financial results and the commercial prospects for any product candidate that we develop would be harmed, our costs could increase, and our ability to generate revenue could be delayed.
If our relationships with any CROs or hospitals where we conduct our current clinical trials terminate, we may not be able to enter into arrangements with alternative CROs and other third parties or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can negatively impact our ability to meet our desired clinical development timelines. While we intend to carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a negative impact on our business, financial condition and prospects.
In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the regulatory authorities, which may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the trial. Such regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the applicable regulatory authority and may ultimately lead to the denial of marketing approval of our product candidates.
Additionally, the FDA, EMA or an IRB may also suspend our clinical trials at any time if it appears that we or our collaborators are failing to conduct a clinical trial in accordance with regulatory requirements, that we are exposing participants to unacceptable health risks, or they find deficiencies in our investigational new drug applications (INDs) or the conduct of these clinical trials. Failures of our CROs to comply with regulations could also cause damage to our reputation and to public perception about our product candidates and technology. Consequently, if we experience delays in our clinical trials, or if we terminate a clinical trial prior to completion, the commercial prospects of our product candidates could be negatively impacted, and our ability to generate revenues from our product candidates may be delayed.
Disruptions at the FDA and other government agencies caused by funding shortages, market conditions or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being advanced, developed, cleared or approved or commercialized in a timely manner or at all, which could negatively impact our business.
Disruptions at the FDA and other agencies, including government budget and funding levels, statutory, regulatory, and policy changes, their ability to hire and retain key personnel as well as impacts resulting from broader market conditions may affect the FDA’s ability to perform routine functions thereby extending the time necessary for new biologics or modifications to be cleared, or approved biologics to be reviewed and approved by necessary government agencies. If a prolonged government shutdown occurs, government funding levels are significantly reduced, or current or future global health concerns prevent the FDA or other regulatory authorities from conducting regulator inspections, reviews or other activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
Regulatory authorities may require concurrent approval of a companion diagnostic device with our product candidates, which could be time consuming and costly and may delay our ability to commercialize such product candidate.
Under the U.S. Federal Food, Drug, and Cosmetic Act, companion diagnostics are regulated as medical devices, and the FDA generally requires pre-market approval (PMA) for companion diagnostics at the same
time as the related product candidate. The PMA application process, including the gathering of analytical and prospective clinical data and the submission to and review by the FDA, is rigorous and requires the applicant to provide the FDA with reasonable assurance of the device’s safety and effectiveness and information about the device and its components regarding, among other things, device design, performance, good manufacturing practices, and labeling. A PMA is not guaranteed and may take considerable time, and the FDA may ultimately respond to a PMA submission with a “not approvable” determination based on deficiencies in the application and require additional clinical trial or other data that may be expensive and time-consuming to generate and that can substantially delay approval.
For LAVA-051 and LAVA-1207, we do not believe it will be necessary to use FDA-cleared or Conformite Europeenne (CE) marked or FDA-approved diagnostic tests to diagnose patients or to assure the safe and effective use of product candidates in clinical trial patients. The approval of a companion diagnostic as part of the therapeutic product’s labeling limits the use of the therapeutic product to only those patients who express the specific marker that the companion diagnostic was developed to detect.
If a regulatory authority requires approval of a companion diagnostic for any of our product candidates, whether before or after it obtains marketing approval, we, and future collaborators, may encounter difficulties in developing and obtaining approval for such product candidate. Any delay or failure by us or third-party collaborators to develop or obtain regulatory approval of a companion diagnostic could delay or prevent approval or continued marketing of such product candidate.
Development of a product candidate intended for use in combination with an already approved therapy may present increased complexity and more or different challenges than development of a product candidate for use as a single agent or monotherapy.
We may develop LAVA-051 and LAVA-1207 and other product candidates for use in combination with approved therapies. We have not studied the benefits and potential challenges or side effects of combination therapies with our product candidates. The FDA, EMA or other comparable regulatory authority may require us to use more complex clinical trial designs to evaluate the contribution of each product and product candidate to any observed effects. It is possible that the results of these clinical trials could show that most or any positive results are attributable to the already approved product. Moreover, following product approval, the FDA, EMA or other comparable regulatory authority may require that products used in conjunction with each other be cross labeled. To the extent that we do not have rights to already approved products, this may require us to work with another company to satisfy such a requirement. Further, developments related to the already approved therapies may impact our clinical trials for the combination as well as our commercial prospects should we receive marketing approval. Such developments may include changes to the approved therapy’s safety or efficacy profile, changes to the availability of the approved therapy, and changes to the standard of care.
If we encounter difficulties in enrolling, qualifying or retaining patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.
The timely completion of clinical trials in part depends on patient enrollment, and as such, identifying and qualifying patients to participate in our LAVA-051 and LAVA-1207 clinical trials and future clinical trials is critical to our success. We may encounter difficulties in enrolling a sufficient number of eligible patients to participate in our clinical trials, thereby delaying or preventing development and approval of our product candidates. Even once enrolled, we may be unable to retain enough patients to complete any of our clinical trials.
We may experience difficulties in patient enrollment for our trials for LAVA-051 and LAVA-1207. Because our focus includes diseases with limited patient populations, there may be limited patient pools from which to draw in order to complete our clinical trials in a timely and cost-effective manner. If any such patient enrolled in any of our clinical trials must drop out due to pre-existing or unrelated health issues or due to a serious adverse effect, or dies, and we are not able to recruit additional patients in a timely manner, or at all, our clinical trials could be delayed or otherwise halted. Consequently, despite diligent planning of our clinical trials
and analysis of their feasibility regarding patient recruitment, we may experience difficulties, delays or inability in patient enrollment in our clinical trials for a variety of reasons, including:
|●||the size and nature of the patient population;|
|●||the severity and incidence of the disease under investigation;|
|●||the design of the trial and the complexity for patients and clinical sites;|
|●||the general health condition of the patient and their immune cells broadly;|
|●||the risk that patients’ general health conditions do not allow the conduct of certain study/screening procedures, the manufacture of therapeutic product or application of the appropriate standard-of-care treatment;|
|●||the ability to consistently manufacture Gammabody product candidates in sufficient quantities at sufficient activity to provide a suitable therapeutic dose;|
|●||competing clinical trials in similar indications for other new therapeutics, new combination treatments, or new medicinal products;|
|●||clinicians’ and patients’ perceptions as to the potential advantages and side effects of the product candidate being studied in relation to other available therapies, including any new drugs or treatments that may be approved or become standard of care for the indications we are investigating;|
|●||the ability to obtain and maintain patients’ consents due to various reasons, including but not limited to, patients’ unwillingness to participate due to the ongoing COVID-19 pandemic;|
|●||the risk that enrolled subjects will drop out or die before completion of the trial;|
|●||the ability to develop and provide appropriate screening, product characterization and release assays;|
|●||patients failing to complete a clinical trial or returning for post-treatment follow-up;|
|●||our ability to manufacture the requisite materials for a patient and clinical trial; and|
|●||inability of clinical sites to enroll patients as health care capacities are required to cope with natural disasters, epidemics or other health system emergencies.|
Our efforts to build relationships with patient communities may not succeed, which could result in delays in patient enrollment in our clinical trials. Any negative results we may report in our LAVA-051 or LAVA-1207 clinical trials may make it difficult or impossible to recruit and retain patients in future clinical trials. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on our ability to develop our product candidates or could render further development impossible.
Serious adverse events (SAEs) or undesirable or unexpected side effects of LAVA-051, LAVA-1207 or future product candidates may be identified during development or after approval, which could lead to the discontinuation of our clinical development programs, refusal by regulatory authorities to approve our product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product candidates thereby limiting the commercial potential of such product candidate.
During the conduct of clinical trials, patients report changes in their health, including illnesses, injuries and discomforts, to their physician. Often, it is not possible to determine whether the product candidate being studied caused these conditions. Regulatory authorities may draw different conclusions or require additional testing to confirm these determinations if they occur. Many times, side effects are only detectable after investigational drugs are tested in large-scale pivotal trials or, in some cases, after they are made available to patients on a commercial scale after approval. If additional clinical experience indicates that any of our product candidates have unacceptable side effects or cause serious or life-threatening side effects, the development of the product candidate may fail or be delayed, or, if the product candidate has received
regulatory approval, such approval may be revoked, which would harm our business, prospects, operating results and financial condition.
Undesirable side effects caused by our product candidates, delivery methods or dosage levels could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EMA or other comparable regulatory authority. As a result of safety or toxicity issues that we may experience in our clinical trials, we may be placed on clinical hold and not receive approval to market any product candidates, which could prevent us from ever generating revenues or achieving profitability. Results of our clinical trials could reveal an unacceptably high severity and incidence of side effects, or side effects outweighing the benefits of our product candidates. In such an event, our studies could be delayed, suspended or terminated and the FDA, EMA or comparable regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The treatment-related side effects could affect patient recruitment or the ability of enrolled subjects to complete the clinical trial or result in potential product liability claims.
To date, we have only tested LAVA-051 and LAVA-1207 in a limited number of patients with cancer and these clinical trial participants have only been observed for a limited period after dosing. We have not yet reported data from any LAVA-051 or LAVA 1207 Phase 2 clinical trial evaluating the potential therapeutic efficacy of LAVA-051 or LAVA-1207. The results of preclinical studies and early clinical trials, as well as data from interim analysis of ongoing clinical trials, may not be predictive of the results of ongoing or future clinical trials.
As we continue developing LAVA-051 and LAVA-1207 and initiate clinical trials of our additional product candidates, unacceptable toxicities, SAEs, undesirable or potentially fatal side effects, CRS, viral infections, relapse of disease or unexpected characteristics may emerge causing us to abandon these product candidates or limit their development to more narrow uses or subpopulations. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff, and inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Should we observe unacceptable toxicities in our clinical trials or identify undesirable side effects or other unexpected findings, our trials could be delayed or even terminated, and our development programs may be halted entirely.
Additionally, if any of our product candidates receives regulatory approval, and we or others later identify undesirable side effects caused by such product, several potentially significant negative consequences could result.
Consequently, such events could diminish the usage or otherwise limit the commercial success of our product candidates and prevent us from achieving or maintaining market acceptance of the affected product candidates, which could have a material adverse effect on our business.
There may be potential unforeseen business disruptions or market fluctuations that delay our business operations, product development, supply chain or clinical trials and increase our costs or expenses, such as business or operational disruptions, delays, or system failures due to malware, general economic and market conditions, overall fluctuations in the United States and international equity markets, including deteriorating market conditions, unauthorized access, terrorism, war, natural disasters, strikes, geopolitical conflicts, restrictions on trade, import or export restrictions, or public health crises, such as the COVID-19 pandemic.
We conduct our clinical trials for our product candidates in the fields of cancer in different geographies, all of which have been affected to varying extents by the COVID-19 pandemic. We believe that the coronavirus pandemic will continue to have an impact on various aspects of our clinical trials. For example, investigators may not want to take the risk of exposing cancer patients to COVID-19 since the dosing of patients is conducted within an in-patient setting. Other potential impacts of the COVID-19 pandemic on our future various clinical trials include patient dosing and study monitoring, which may be paused or delayed due to changes in policies at various clinical sites, federal, state, local or foreign laws, rules and regulations, including quarantines or other travel restrictions, prioritization of healthcare resources toward pandemic efforts, including diminished attention of physicians serving as our clinical trial investigators and reduced
availability of site staff supporting the conduct of our clinical trials, interruption or delays in the operations of the government regulators, or other reasons related to the COVID-19 pandemic. It is unknown how long these pauses or disruptions could continue.
Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data becomes available and are subject to audit and verification procedures that could result in material changes in the final data.
From time to time, we may publish interim, “top-line” or preliminary data from our clinical trials for LAVA-051 or LAVA-1207 or future clinical trials. Interim, “top-line” or preliminary data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Interim, “top-line” and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim, “top-line,” and preliminary data should be viewed with caution until the final data are available. Differences between interim, “top-line” and preliminary data and final data could significantly harm our business prospects and may cause the trading price of our common shares to fluctuate significantly.
Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our business in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product candidate or our business. If the interim, “top-line,” or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for and commercialize our product candidates, our business, operating results, prospects or financial condition may be harmed.
We face significant competition, and many of our competitors have substantially greater experience and resources than we have. Our competitors may achieve regulatory approval before us or develop therapies that are more advanced or effective than ours, which may adversely affect our financial condition and our ability to successfully market or commercialize our product candidates.
The clinical and commercial landscape in the indications we are targeting, as well as in the field of immuno-oncology, is highly competitive. We face potential competition with respect to our current product candidates and may face competition with respect to any other product candidates that we may seek to develop or commercialize in the future from pharmaceutical and biotechnology companies, academic institutions, government agencies and other public and private research institutions.
Many of our current or potential competitors, alone or with their strategic partners, have greater financial resources, larger research and development staffs, and more experience in researching, developing and testing products than we do. They may have more experience in conducting clinical trials, obtaining FDA and other regulatory approvals, and manufacturing, marketing and distributing therapeutic products. Smaller companies like us may successfully compete by establishing collaborative relationships with larger pharmaceutical companies or academic institutions. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors.
Our competitors in the field of gamma delta T cell therapy include Adicet Bio, Inc., Editas Medicine, Inc., Eureka Therapeutics, Inc., Gadeta BV, ImCheck Therapeutics SAS, Immatics Biotechnologies GmbH, IN8bio, Inc., Leucid Bio Ltd, PhosphoGam Inc., Shattuck Labs Inc., Sandhill Therapeutics, Inc, Takeda Pharmaceutical Company Ltd, and TC BioPharm Limited. Our gamma delta T cell product candidates may also compete with other T cell and NK cell engaging therapies as well as NK cell-engaging therapies.
There are many other companies that have commercialized or are developing immuno-oncology therapies for cancer including large biotechnology and pharmaceutical companies, such as Amgen, AstraZeneca, BMS, Eli Lilly and Company, EMS Serono, Genentech, a subsidiary of Roche, Merck & Co., Merck KGa, EMD, Serono, Novartis, Pfizer, Sanofi and Takeda. Many companies, not limited to those above, are attempting to combine immuno-oncology antibody therapies in order to modulate two cancer pathways simultaneously. Others have developed bispecific antibodies or bispecific fusion proteins to leverage the effect of a combination of single-target traditional monoclonal antibodies, which we refer to as traditional antibodies, in a single molecule.
Many of our potential competitors, alone or with their strategic partners, compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive than any products that we may develop. Furthermore, currently approved products could be discovered to have application for treatment of cancer and other diseases. Our competitors may succeed in developing, obtaining patent protection for, or commercializing their products more rapidly than us, which could result in our competitors establishing a strong market position before we are able to enter the market. Consequently, we may not be successful in marketing any product candidates we may develop against competitors.
Risks related to manufacturing and reliance on third parties
The manufacture of biotechnology products is complex, and manufacturers often encounter difficulties in production, which could negatively affect our ability to develop or commercialize our product candidates.
The manufacture of biotechnology products is complex and requires significant expertise and capital investment. We and our contract manufacturers must comply with cGMP regulations and guidelines for clinical trial product manufacture and for commercial product manufacture. We may encounter difficulties in production of LAVA-051, LAVA-1207 or our other product candidates, particularly in scaling up, addressing product quality, product comparability, validating production processes and mitigating potential sources of contamination. These difficulties include:
|●||challenges procuring raw materials;|
|●||maintaining quality control for our products, including stability of products, quality assurance testing, issues arising from operator error;|
|●||retaining qualified personnel for manufacturing processes;|
|●||inability to meet our product specifications and quality requirements consistently;|
|●||delay or inability to procure or expand sufficient manufacturing capacity;|
|●||issues related to scale-up of manufacturing;|
|●||costs and validation of new equipment and facilities required for scale-up;|
|●||reliance on third party suppliers and manufacturers;|
|●||compliance with cGMP requirements and other inspections by the FDA, EMA or other comparable regulatory authorities.|
|●||the cost and timing of establishing, expanding and scaling manufacturing capabilities;|
|●||inability to manufacture, or obtain from third parties, sufficient quantities of qualified materials under cGMPs, for the completion in pre-clinical and clinical studies; and|
|●||problems with biopharmaceutical product candidate storage, stability and distribution resulting from global supply chain disruptions.|
In addition, if microbial, viral or other contaminations are discovered in therapeutic products or in the manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination.
Any adverse developments affecting manufacturing operations for LAVA-051, LAVA-1207 and our other and future product candidates may result in lot failures, inventory shortages, shipment delays, product withdrawals, recalls or other interruptions in the supply of our drug product, which could prevent the administration to patients and delay the development of our product candidates. We may also have to write off inventory, incur other charges and expenses for supply of drug product that fails to meet specifications, undertake costly remediation efforts, or seek more costly manufacturing alternatives. In such event, it would negatively impact our ability to generate revenue, harm our reputation, and could have an adverse effect on our business and financial condition.
For certain product candidates we have relied on a single-source supplier for bulk drug substance (BDS) and drug manufacturing. The loss of this supplier or its failure to supply us with BDS on a timely basis could impair our ability to develop our product candidates or otherwise delay the development process, which could adversely affect our business.
We currently depend on one single-source supplier for certain of our product candidates. In the event we lose our single-source supplier, our ability to develop our product candidates will likely be adversely impacted and delayed, which could adversely affect our business. We have completed the transfer of the manufacturing process for LAVA-051 to a second BDS supplier which is expected to become operational in the third quarter of 2023. Although we have transferred our manufacturing process for LAVA-051 to a second BDS supplier, there can be no assurance that we will be successful in manufacturing or if we will be able to do so on a timely basis, which could adversely affect our business. There are no immediate plans to select a second BDS supplier for LAVA-1207.
Although we believe that we have a substantial reserve of BDS to support each of our current clinical trial programs, there can be no assurance that our supply of BDS will not be limited, interrupted, or of satisfactory quality or continue to be available at acceptable prices. Additionally, we do not have any control over the process or timing of the acquisition or manufacture of materials by our supplier and cannot ensure that it will deliver to us the BDS we order on time, or at all. The loss of BDS provided by this supplier could require us to change the design of our product candidate development process based on the functions, limitations, features and specifications of the replacement.
In addition, the lead time needed to establish a relationship with a new supplier can be lengthy, and we may experience delays in meeting demand in the event we must switch to a new supplier. The time and effort to qualify a new supplier could result in additional costs, diversion of resources or reduced manufacturing yields, any of which would negatively impact our operating results. Our reliance on this single-source supplier exposes us to certain risks, including:
|●||our supplier may cease or reduce production or deliveries, raise prices or renegotiate terms;|
|●||we may be unable to locate a suitable replacement on acceptable terms or on a timely basis, if at all; and|
|●||if there is a disruption to our single-source supplier’s operations, and if we are unable to enter into arrangements with alternative suppliers, we may need to halt our clinical trial programs;|
The manufacturing of our product candidates may also be affected by the growth in the costs and expenses of components or raw materials for such product candidates. Likewise, supply sources could be interrupted from time to time and, if interrupted, there is no guarantee that supplies could be resumed (whether in part or in whole) within a reasonable timeframe and at an acceptable cost or at all. Furthermore, subsequent orders of the same supplies may be according to different specifications, which could cause delays in our manufacturing process.
Any adverse developments affecting manufacturing operations for our product candidates, if any are approved, may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, cost increases or other interruptions in the supply of our product candidates, which could delay our clinical trials and materially impact our business and operations.
We currently store our Gammabody product candidates at specialized external storage facilities operating under established rules and regulations, and any damage or loss to storage freezers if not detected and remediated in time, would cause delays in replacement, and our business could suffer.
All our Gammabody product candidates are manufactured from a vial of a master cell bank or a working cell bank of that antibody’s production cell line. We have or intend to have one master cell bank for each bispecific T cell engager (bsTCE) that was or will be produced and tested in accordance with cGMP and applicable regulations. Any adverse developments affecting manufacturing operations for our product candidates while they are undergoing clinical trials could delay the timeline on which such trials are being conducted.
Our master and working cell banks are stored at multiple specialized external storage facilities operating under established rules and regulations. If these cells are damaged, including by the loss or malfunction of liquid nitrogen filled Dewar vessels or freezers, or back-up power systems, as well as by damage from fire, power loss or other natural disasters, we would need to establish replacement cell banks, which could impact clinical supply and could delay our clinical trials. We would also need another supplier with a good manufacturing process (GMP) facility. If we or our third-party contractors are unable to establish replacement cell banks, as applicable, we could incur significant additional expenses and liability, our development programs could be delayed or terminated, and our business could suffer.
If we cannot manufacture our product candidates or the product candidates of our collaborations reliably or in sufficient amounts utilizing Contract Development Manufacturing Organizations (CDMOs) or ourselves, at acceptable costs and on a timely basis, we may be unable to supply sufficient product candidates for nonclinical studies or clinical trials or to support commercialization of our product candidates, if approved.
We do not own or operate manufacturing facilities and have no plans to build our own clinical or commercial-scale manufacturing capabilities. We cannot ensure that our suppliers will remain in business, have sufficient capacity or supply to meet our needs, or that they will not be purchased by one of our competitors or another company that is not interested in continuing to work with us. If we cannot establish sufficient supply through alternative third-party CDMOs or in our own facilities, should we develop these, our ability to conduct the planned and future clinical trials and our plans for commercialization would be materially adversely affected.
In addition, we currently rely on a small number of CDMOs for the production of certain of our product candidates and our collaborations and, as a result, face certain additional risks relating to our manufacturing operations. A single significant disruptive event at the manufacturing operations of one of our CDMOs can have a material adverse effect on our business, prospects, financial condition and results of operations. Business interruption insurance may not adequately compensate us for any losses that may occur and we would have to bear the additional cost of any disruption. For instance, if we were to experience an unexpected loss of supply, or if our CDMOs are unable to meet our demand for our product candidates or their services, we could experience delays in our research and development activities, planned clinical trials or commercialization of approved products. Finding alternative CDMOs or suppliers of acceptable quality who can deliver appropriate volumes at acceptable cost may require additional time and resources. Moreover, the transition periods involved in the change of CDMOs and suppliers, if necessary, could significantly delay our clinical trials and the commercialization of our product candidates, if approved.
Manufacturers of drug and biological products often encounter difficulties in production, particularly in scaling up or out, validating the production process, and assuring high reliability of the manufacturing process (including the absence of contamination). These problems include logistics and shipping, difficulties with production costs and yields, quality control, including stability of the product, product testing, operator error, availability of qualified personnel, as well as compliance with strictly enforced federal, state and non-U.S. regulations. Furthermore, if contaminants are discovered in the supply of our drug product or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended period to investigate and remedy the contamination. We cannot assure you that any stability failures or other issues relating to the manufacture of our product candidates will not occur in the future. Any delay or interruption in the supply of clinical trial supplies could delay the completion of clinical trials, increase the costs associated
with maintaining clinical trial programs and, depending upon the period of delay, require us to begin new clinical trials at additional expense or terminate clinical trials completely.
We will need to work with CDMOs that can meet all applicable FDA and other regulatory authority requirements on an ongoing basis. If the manufacturing process is changed during product development, the FDA or other regulatory authorities could require us to repeat some or all previously conducted trials or conduct additional trials to obtain bridging data, which could delay or impede our ability to obtain marketing approval. If we or our CDMOs are unable to reliably produce and release our product candidates to specifications acceptable to FDA or other regulatory authorities, we may not obtain or maintain the approvals we need to further develop, conduct clinical trials for, and commercialize such product candidates. Similarly, approval of our product candidates could be delayed or denied if the intended manufacturing site fails to pass the required preapproval inspection. Even if we obtain regulatory approval for any of our product candidates, there is no assurance that either we or our CDMOs will be able to manufacture the approved product to specifications acceptable to the FDA or other regulatory authorities, to produce it in sufficient quantities to meet the requirements for the potential launch of the product, or to meet potential future demand. Any of these challenges could delay completion of clinical trials, require clinical trials to obtain bridging data or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates, impair commercialization efforts, increase our cost of goods, and have a material adverse effect on our business, financial condition, results of operations and growth prospects.
Future clinical trials that we conduct, as well as any potential commercialization of our product candidates when approved, will depend on the reliability, safety and efficacy of our manufacturing methodology. Our efforts to scale up production of our bispecific gamma delta T cell engager antibodies in anticipation of future clinical trials or commercialization may reveal defects in our methodology, an inability to overcome biology or may otherwise encounter challenges, including scrutiny from regulatory authorities. To the extent we encounter any such difficulties, our ability to conduct additional clinical trials or to scale for commercialization will be hindered or prevented, which would have an adverse effect on our business.
Risks related to our intellectual property
Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues. If we are unable to obtain or protect rights relating to our technology and future product candidates, or if our intellectual property rights are inadequate, we might not be able to compete effectively.
We have entered into license agreements and agreements where we have received a contingent assignment to certain patent rights with third parties and we expect to enter into additional such agreements in the future to advance our research or allow commercialization of LAVA-051, LAVA-1207 or any future product candidates we may develop. These license agreements impose financial and other obligations that are relevant to our business and financial operations, and if we fail to comply with our obligations under these agreements, we could lose our rights, or face further liability, under such license agreements. For example, if we fail to meet our obligations under the VUmc Agreement in any material respect and fail to cure such breach in a timely fashion, VUmc may terminate the agreement, and we would be obligated to transfer back to VUmc the assigned patent rights. While we would expect to exercise all rights and remedies available to us, including seeking to cure any breach by us, and otherwise seek to preserve our rights under the agreement, we may not be able to do so in a timely manner, at an acceptable cost or at all. For more information on the VUmc Agreement, see “Item 4: Information on the Company.” If these agreements are terminated, we could lose intellectual property rights that are important to our business, be liable for damages to such licensors or be prevented from developing and commercializing our product candidates. Termination of these agreements or reduction or elimination of our rights under these agreements may also result in our being required to negotiate new or reinstated agreements with less favorable terms, and it is possible that we may be unable to obtain any such additional licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to redesign our product candidates or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis.
License agreements we enter into in the future may not provide exclusive rights to use intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and products. As a result, we may not be able to prevent competitors from developing and commercializing competitive products in territories included in all our licenses.
Disputes may arise between us and our current or future licensors regarding intellectual property subject to a license agreement, including:
|●||the scope of rights granted under the license agreement and other interpretation-related issues;|
|●||whether and the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;|
|●||our right to sublicense, transfer or assign patents and other rights to third parties;|
|●||our diligence obligations under the license agreement and what activities satisfy those diligence obligations;|
|●||the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and|
|●||the priority of invention of patented technology.|
In addition, the agreements under which we license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could significantly harm our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could significantly harm our competitive position, business, financial condition, results of operations and prospects.
If we are unable to obtain and maintain patent and other intellectual property protection for our product candidates and technology, or if the scope of protection obtained is not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability to successfully commercialize our product candidates and technology may be adversely affected.
Our success depends in part on our ability to obtain and maintain protection for our owned and in-licensed intellectual property rights and proprietary technology. We rely on patents and other forms of intellectual property rights, including in-licenses of intellectual property rights and biologic materials of others, to protect our current or future discovery platform, product candidates, methods used to manufacture our future product candidates, and methods for treating patients using our future product candidates.
We and our licensors have sought, and intend to seek, to protect our proprietary position by filing patent applications in the United States and abroad related to our product candidates and our technology that are important to our business including LAVA-051 and LAVA-1207. We may also seek to protect our proprietary position by acquiring or in-licensing additional issued patents or pending patent applications from third parties.
As of December 31, 2022, we own, co-own or exclusively license three issued U.S. patents, seven pending U.S. patent applications, seven pending European regional-phase patent applications, three pending Patent Cooperation Treaty (PCT) patent applications, eight issued patents in other territories and more than forty pending patent applications in other territories, which are important to the development of our business. For more information relating to our patent portfolio, see “Item 4: Information on the Company.” If we or our licensors are unable to obtain and maintain intellectual property protection with respect to inventions and technology important to our business, our competitive position, financial condition, results of operations and prospects may be significantly harmed.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has, in recent years, been the subject of much litigation. Since patent applications in the United States and most other countries are confidential for a period after filing, and some remain so until issued, we cannot be certain that we or our licensors were the first to file a patent application relating to any particular aspect of a product candidate or technology. As a result of these and other factors, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our and our licensors’ pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may also diminish the value of our patents or narrow the scope of our patent protection.
Pending patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents have been issued from such applications, and then only to the extent the issued claims cover the technology. Although we enter into non-disclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development activities, any of these parties may breach the agreements and disclose such activities before a patent application is filed, thereby jeopardizing our ability to seek patent protection.
Moreover, we may be subject to a third-party pre-issuance submission of prior art or become involved in opposition, derivation, reexamination, inter partes review, post-grant review, interference or other similar proceedings, or litigation, challenging our patent rights or the patent rights of our licensors. The costs of defending our patents or enforcing our proprietary rights in such administrative proceedings or litigation can be substantial and the outcome can be uncertain. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates or could embolden competitors to launch products or take other steps that could disadvantage us in the marketplace or draw us into additional expensive and time-consuming disputes.
The patent prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patent applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.
We or our licensors have not pursued or maintained, and may not pursue or maintain in the future, patent protection for our product candidates in every country or territory in which we may sell our products, if approved. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from infringing our patents in all countries outside the United States, or from selling or importing products that infringe our patents in and into the United States or other jurisdictions.
Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if the patent applications we license or own do issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us or otherwise provide us with any competitive advantage. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative products in a non-infringing manner.
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, which
could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and product candidates.
Furthermore, we may develop, acquire or license intellectual property rights that have been generated through the use of Dutch or U.S. government funding. As a result, the Dutch or U.S. government may have certain rights, or march-in rights, to such patent rights and technology. Typically, the government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In certain circumstances, the government may also have the right to take title to these inventions if the grant recipient fails to disclose the invention to the government or fails to file an application to register the intellectual property within specified time limits. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the country. Any exercise by the government of such rights could harm our competitive position, business, financial condition, results of operations and prospects.
We may also be subject to claims challenging the inventorship or ownership of our patents and other intellectual property. It is possible that we do not perfect our ownership of all patents, patent applications and other intellectual property, including that we do not identify all inventors, or identify incorrect inventors, which may lead to claims disputing inventorship or ownership of our patents, patent applications or other intellectual property by former employees or other third parties or that we do not establish an unbroken chain of title from inventors to us. Errors in inventorship or ownership can sometimes also impact priority claims. If we were to lose ability to claim priority for certain patent filings, intervening art or other events may preclude us from issuing patents. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership.
Obtaining and maintaining our patent rights depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or patent applications will have to be paid to the United States Patent and Trademark Office (USPTO) and various government patent agencies outside the United States over the lifetime of our owned and licensed patents and/or applications and any patent rights we may own or license in the future. We rely on our outside counsel or our licensing partners and other professionals to help us comply with these requirements and pay these fees when due, and we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our licensed intellectual property. Noncompliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, nonpayment of fees and failure to properly legalize and submit formal documents. In some cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in a partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market and this circumstance could harm our business.
Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
Depending upon the timing, duration and specifics of FDA marketing approval of any product candidates we may develop, one or more of our U.S. patents may be eligible for a limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent term extension of up to five years beyond the normal expiration of the patent as compensation for patent term lost during product development and the FDA regulatory review process. However, the extension cannot extend the total patent term beyond 14 years from the date of product approval and is limited to the approved indication (or any additional indications approved during the period of extension). Furthermore, only one patent per approved product can be extended and only those claims covering the approved product, a method for using it or a method for manufacturing it may be extended. Similar provisions are available in Europe, Japan and other jurisdictions to extend the term of a
patent that covers an approved drug; however, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevancy patents or otherwise failing to satisfy applicable requirements, or may grant more limited extensions than we request. If this occurs, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. Additionally, our competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case, any of which could harm our competitive position, business, financial condition, results of operations and prospects.
Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property or other proprietary rights, the outcome of which would be uncertain and could have a negative impact on the success of our business.
Our commercial success depends, in part, upon our ability and the ability of others with whom we may collaborate to develop, manufacture, market and sell our current and any future product candidates and use our proprietary technologies without infringing, misappropriating or otherwise violating the intellectual property and other proprietary rights of third parties. The biotechnology and pharmaceutical industries are characterized by extensive and complex litigation regarding patents and other intellectual property rights.
We, or our licensors, or any future strategic partners may in the future become party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our current and any future product candidates and technology, including oppositions, interference proceedings, reexaminations, post grant review, inter partes review or derivation proceedings before the USPTO in the United States, or any equivalent regulatory authority in other countries. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. These proceedings can be expensive and time-consuming, and many of our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions. Even if we believe such claims are without merit, there is no assurance that a court would find in our favor on questions of validity, enforceability, priority or non-infringement. A court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, which could have a negative impact on our ability to commercialize our current and any future product candidates. To successfully challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity. As this is a high burden and requires us to present clear and convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such U.S. patent.
Intellectual property rights of third parties could adversely affect our ability to commercialize our current or future technologies or product candidates, and we might be required to litigate or obtain licenses from third parties to develop or market our current or future technologies or product candidates, which may not be available on commercially reasonable terms or at all.
Given the vast number of patents in our field of technology, we cannot be certain that we do not infringe existing patents or that we will not infringe patents that may be granted in the future. Other companies and research institutions have filed, and may file in the future, patent applications related to gamma delta T cell immunotherapy. Some of these patent applications have already been allowed or issued, and others may issue in the future. While we may decide to initiate proceedings to challenge the validity of these or other patents in the future, we may be unsuccessful, and courts or patent offices in the United States and abroad could uphold the validity of any such patent. Furthermore, because patent applications can take many years to issue and may be confidential for 18 months or more after filing, and because pending patent claims can be revised before issuance, there may be applications now pending which may later result in issued patents that may be infringed by the manufacture, use or sale of our product candidates. Regardless of when filed, we may fail to identify relevant third-party patents or patent applications, or we may incorrectly conclude that a
third-party patent is invalid or not infringed by our product candidates or activities. If a patent holder believes that our product candidate infringes its patent, the patent holder may sue us even if we have received patent protection for our technology. Moreover, we may face patent infringement claims from non-practicing entities that have no relevant drug revenue and against whom our own patent portfolio may thus have no deterrent effect. If a patent infringement suit were threatened or brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the drug or product candidate that is the subject of the actual or threatened suit.
If we are found to infringe, misappropriate or otherwise violate a third party’s valid and enforceable intellectual property or other proprietary rights, we could be required to obtain a license from such third party to continue developing, manufacturing and marketing our product candidate(s) and technology. Under any such license, we would most likely be required to pay various types of fees, milestones, royalties or other amounts. Moreover, we may not be able to obtain any required license on commercially reasonable terms or at all. We could be forced, including by court order, to cease developing, manufacturing and commercializing the infringing technology or product candidate. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. We may also be required to indemnify collaborators or contractors against such claims. A finding of infringement, misappropriation or other violation of third-party intellectual property could prevent us from manufacturing and commercializing our current or any future product candidates or force us to cease some or all our business operations, which could harm our business.
The licensing or acquisition of third-party intellectual property rights is a competitive area, and more established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may have to abandon development of the relevant program or product candidate, which could have an adverse effect on our business, financial condition, results of operations and prospects. Furthermore, even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments.
We may be subject to claims asserting that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.
Certain of our employees, consultants and advisors are currently, or were previously, employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals, or we, have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims, regardless of their merit, and we cannot predict whether we would prevail in any such actions. Our failure in defending any such claims, in addition to paying monetary damages, may cause us to lose valuable intellectual property rights or personnel and may prevent or delay our development and commercialization efforts, which could significantly harm our business, financial condition, results of operation and prospects. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and may cause negative publicity.
In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may in the future be subject to claims by our former employees or consultants asserting an ownership right in our patents or patent applications because of work they performed on our behalf. We may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own, and we cannot be certain that our agreements with such parties will be upheld in the face of a potential challenge. The assignment of intellectual property rights may
not be self-executing or the assignment agreements may be breached, for which we may not have an adequate remedy, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have an adverse effect on our business, financial condition, results of operations and prospects.
We may be involved in lawsuits to protect or enforce our patents, the patents of our licensors or our other intellectual property or proprietary rights, which could be expensive, time-consuming and unsuccessful.
Competitors or other third parties may infringe, misappropriate or otherwise violate our patents, the patents of our licensors or our other intellectual property or proprietary rights. To counter infringement, misappropriation or unauthorized use, we may be required to file infringement or other intellectual property claims, which can be expensive and time-consuming and are likely to divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. In addition, in a patent infringement proceeding, a court may decide that a patent of ours or our licensors is not valid, is unenforceable, and/or is not infringed, or may refuse to stop the other party from using the technology at issue on the grounds that our owned or licensed patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our owned or licensed patents at risk of being invalidated or interpreted narrowly and could put our owned or licensed patent applications at risk of not issuing. Such proceedings could result in the revocation of, cancellation of, or amendment to our patents in such a way that they no longer cover our technology or platform, or any product candidates that we may develop. The outcome following legal assertions of invalidity and unenforceability is unpredictable. We cannot be certain that there is or will be no invalidating prior art, of which we and the patent examiner were unaware during prosecution. For the patents and patent applications that we have licensed, we may have limited or no right to participate in the defense of any licensed patents against challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of any future patent protection on our current or future product candidates.
We may not be able to prevent, alone or with our licensors, infringement, misappropriation or other violations of our intellectual property and proprietary rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Any litigation or other proceedings to enforce our intellectual property and proprietary rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.
We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios.
Accordingly, despite our efforts, we may not be able to prevent third parties from infringing, misappropriating or otherwise violating or from successfully challenging our intellectual property and proprietary rights. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have an adverse effect on our ability to compete in the marketplace.
Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our current and any future product candidates.
Changes in either the patent laws or interpretation of the patent laws in the United States and other countries could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. Under the Leahy-Smith America Invents Act, or the America Invents Act, the United States transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. The America Invents Act also allows third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO-administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. The America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent
applications and the enforcement or defense of our issued patents, all of which could have an adverse effect on our business, financial condition, results of operations, and prospects.
In addition, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty about our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts, and the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce patents that we own, have licensed or might obtain in the future. Changes in patent law and regulation in other countries or jurisdictions, changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we own or have licensed or that we may obtain in the future.
We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business.
Filing, prosecuting and defending patents covering our current and any future product candidates in all countries throughout the world would be prohibitively expensive, and our and our licensors’ intellectual property rights in some countries outside the United States may be less extensive than those in the United States. Competitors may use our technologies in jurisdictions where we or our licensors have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we may obtain patent protection but where patent enforcement is not as strong as that in the United States. These products may compete with our products in jurisdictions where we do not have any issued or licensed patents, and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement, misappropriation or other violation of our or our licensors’ patents or marketing of competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property and proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents or the patents of our licensors at risk of being invalidated or interpreted narrowly, could put our patent applications or the patent applications of our licensors at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.
Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected.
Reliance on third parties requires us to share our know-how or trade secrets, which increases the possibility that a competitor will discover them or that our know-how or trade secrets will be misappropriated or disclosed.
Since we rely on third parties to help us discover, develop, and manufacture our current and any future product candidates, or if we collaborate with third parties for the development, manufacturing or commercialization of our current or any future product candidates, we must, at times, share know-how or trade secrets with them. We may also conduct joint research and development programs that may require us
to share know-how or trade secrets under the terms of our research and development partnerships or similar agreements. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our know-how or trade secrets. Despite the contractual provisions employed when working with third parties, the need to share know-how or trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure could have an adverse effect on our business and results of operations. In addition, from time to time, we may hire scientists or other employees or consultants who originate from jurisdictions, including China, which have a history of engaging in misappropriation or theft of trade secrets or other acts of trade secret espionage. If any such individuals are found to be engaging in such illegal behavior, it could have a material adverse effect on our ability to protect our intellectual property and our business prospects more generally.
In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors, and consultants to publish data potentially relating to our know-how or trade secrets. Despite our efforts to protect our know-how and trade secrets, we may not be able to prevent the unauthorized disclosure or use of our technical know-how or other trade secrets by the parties to these agreements. Moreover, we cannot guarantee that we have entered into such agreements with each party that may have or have had access to our confidential information or proprietary technology and processes. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary technologies will be effective. If any of the collaborators, scientific advisors, employees, contractors, and consultants who are parties to these agreements breaches or violates the terms of any of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets as a result. Moreover, if confidential information that is licensed or disclosed to us by our partners, collaborators, or others is inadvertently disclosed or subject to a breach or violation, we may be exposed to liability to the owner of that confidential information. Enforcing a claim that a third-party illegally or unlawfully obtained and is using our trade secrets, like patent litigation, is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets.
If we are unable to protect the confidentiality of our know-how or trade secrets, our business and competitive position would be harmed.
Our competitors may independently develop knowledge, methods, and know-how equivalent to our trade secrets. Competitors could purchase our products and replicate some or all of the competitive advantages we derive from our development efforts for technologies on which we do not have patent protection. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or third party, we would have no right to prevent them, or those to whom they communicate such trade secrets, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced, and our competitive position would be harmed.
We also seek to preserve the integrity and confidentiality of our data and other confidential information by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be breached, and detecting the disclosure or misappropriation of confidential information and enforcing a claim that a party illegally disclosed or misappropriated confidential information is difficult, expensive and time-consuming, and the outcome is unpredictable. Further, we may not be able to obtain adequate remedies for any breach. In addition, our confidential information may otherwise become known or be independently discovered by competitors, in which case we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us.
If our trademarks are not adequately protected, then we may not be able to build name recognition in our markets of interest, resulting in harm to our business.
We have registered trademarks and pending trademark applications in the United States and various foreign jurisdictions for our marks related to our business. We have not yet selected trademarks for our product candidates and have not yet begun the process of applying to register trademarks for any of our current or future product candidates. Whether allowed or registered, our trademarks and trade names may be challenged, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devote resources to advertising and marketing new brands. Our competitors may infringe our trademarks, or adopt trademarks similar to ours, and there may be trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks, and we may not have adequate resources to enforce our rights in such trademarks. Over the long term, if we are unable to establish name recognition based on our trademarks, then we may not be able to compete effectively, and our competitive position, business, financial condition, results of operations and prospects may be significantly harmed.
In addition, any proprietary name we propose to use with our current or any other product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product names, we may be required to expend significant additional resources in an effort to identify a suitable proprietary product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA.
Intellectual property rights do not necessarily address all potential threats to the competitive advantages maintained by our business.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:
|●||others may be able to make compounds or formulations that are similar to our product candidates but that are not covered by the claims of any patents, should they issue, that we own or license;|
|●||we or our licensors might not have been the first to make the inventions covered by the issued patents or pending patent applications that we own or license;|
|●||we or our licensors might not have been the first to file patent applications covering certain of our or their inventions;|
|●||others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;|
|●||we or our licensors may not be able to detect infringement of issued patents we own or license;|
|●||it is possible that pending patent applications we own or in-license will not lead to issued patents;|
|●||issued patents that we own or license may not provide us with any competitive advantages, or may be held invalid or unenforceable as a result of legal challenges;|
|●||issued patents that we own or license may not have sufficient term or geographic scope to provide meaningful protection;|
|●||our competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not have patent rights, and then use the information learned from such activities to develop competitive drugs for sale in our major commercial markets;|
|●||we may not develop additional proprietary technologies that are patentable;|
|●||the patents of others may have an adverse effect on our business; and|
|●||we may choose not to file a patent to maintain certain trade secrets, and a third party may subsequently file a patent covering such intellectual property.|
Should any of these events occur, it could significantly harm our business, financial condition, results of operation and prospects.
Risks related to our business operations, employee matters and managing growth
We plan to expand our organization, and we may experience difficulties in managing this growth, which could disrupt our operations.
As of December 31, 2022, we had 69 full-time employees. As the clinical development of our product candidates progresses, we expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of research, drug development, regulatory affairs and, if any of our product candidates receives marketing approval, sales, marketing and distribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.
We are and expect to continue to be reliant on third parties for key aspects of our business and operations, including our existing and future research, manufacturing and supply. If such parties fail to adequately perform or we are not able to maintain our current relationships or enter new strategic relationships which such third parties, our business, financial condition, commercialization prospects and results of operations may be adversely affected.
We are reliant on third parties for key aspects of our business and operations, including the development our existing and future research programs and product candidates, implementation and management of our clinical trials, and manufacturing and supply of our products and product candidates. Reliance on third parties exposes us to additional risks and uncertainties that may not exist if we were able to manage such aspects of our business ourselves.
We are currently a party to a research collaboration and license agreement (Janssen Agreement) with Janssen Biotech, Inc. (Janssen), for the potential discovery and development of multi-specific antibody products that are directed to a specified target in all fields of use. We also intend to explore other strategic partnerships to broaden our Gammabody platform. Because we do not own any facility that may be used as our clinical or commercial-scale manufacturing and processing facility, we expect to rely on third parties for at least a portion of our manufacturing process. In addition, we have a commercial supply agreement for the manufacturing of LAVA-051 with a global contract manufacturer. Reliance on such third parties and other manufacturers and suppliers may pose several risks, including that such third parties:
|●||may not have sufficient resources or devote the necessary resources to our relationship due to internal constraints such as budget limitations, lack of human resources, or a change in strategic focus;|
|●||may believe our intellectual property is not valid or is unenforceable, or that the product candidates subject to the arrangement infringes, misappropriates or otherwise violates the intellectual property rights of others;|
|●||may dispute their responsibility to conduct development and commercialization activities, including the payment of related costs or the division of any revenues;|
|●||may decide to pursue a competitive product developed outside of the collaboration arrangement;|
|●||may not be able to obtain, or believe they cannot obtain, the necessary regulatory approvals or certifications or comply with cGMP requirements;|
|●||may experience challenges in manufacturing to our specifications and in compliance with regulatory requirements; or|
|●||may delay the development or commercialization of our product candidates in favor of developing or commercializing another party’s product candidate.|
In addition, we may not be able to negotiate commercial arrangements with any of such parties on acceptable terms, if at all. Our ability to reach a definitive agreement for a collaboration, clinical development, manufacturing or supply will depend, among other things, upon our assessment of the third party’s resources and expertise, the terms and conditions of the proposed commercial relationship and the proposed third party’s evaluation of a number of factors. If we are unable to reach agreements with suitable third parties on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay one or more of our other development programs, delay our potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all.
We are unable to predict when, if ever, we will enter into any such relationships because of the numerous risks and uncertainties associated with establishing them, including:
|●||expenditure of substantial operational, financial and management resources;|
|●||dilutive issuances of our securities to such third parties;|
|●||substantial actual or contingent liabilities; and|
|●||termination or expiration of the arrangement, which would delay the development and may increase the cost of developing our product candidates.|
We may also be subject to further risks if our third-party providers do not properly maintain, enforce or defend our intellectual property rights or may use our proprietary information in a manner that could jeopardize or invalidate our proprietary information or expose us to potential litigation, any of which could adversely affect our business, financial position and operations.
All the risks relating to product development, regulatory approval and commercialization applicable to us, including those described in this “Risk Factors” section, also apply to the activities of our program collaborators. Additionally, subject to its contractual obligations to us, if one of our collaborators is involved in a business combination, the collaborator may deemphasize or terminate the development or commercialization of any product candidate licensed to it by us. If our collaborator terminates its agreement with us, we may find it more difficult to attract new collaborators, which could negatively impact our ability to develop or commercialize such product candidate.
If our collaboration with Seagen is delayed or terminated, or if Seagen materially breaches its obligations thereunder, it could cause significant delays in the development efforts of the Gammabody platform.
Our financial performance may be significantly harmed if the collaboration with Seagen to develop SGN-EGFRd2 (LAVA-1223), an investigational candidate targeting epidermal growth factor receptor (EGFR), is delayed or terminated. Under the Seagen Agreement, Seagen paid us a non-refundable upfront payment of $50.0 million and has the option to obtain exclusive rights to two (2) additional targets, subject to an option payment for each product candidate. If Seagen exercises its option on a given product candidate, we will develop such target candidate. We also have an option to elect to co-fund SGN-EGFRd2 (LAVA-1223), at a certain opt-in price at a designated time pursuant to the Seagen Agreement. Additionally, we will be entitled to royalties on any future sales of such products by Seagen. If Seagen were to terminate our collaboration agreement, we may not have the resources or skills to replace those of our collaborator, which could require us to seek additional funding or another collaboration that might not be available on favorable terms or at all, and could cause significant delays in development and/or commercialization efforts, including delays in validating our Gammabody platform, and result in substantial additional costs to us. Termination of such
collaboration agreement or the loss of rights provided to us under such agreement may create substantial new and additional risks to the successful development and commercialization of our products and could materially harm our reputation, financial condition and operating results. It is difficult to predict how Seagen's business strategy will change over time; as of now we have no indication that they will abandon the program, which would effectively end our contract and future milestones. We continue to hold regular governance and team meetings, and Seagen appears engaged in the SGN-EGFRd2 (LAVA-1223) collaboration.
Our business and operations may be adversely affected by economic downturns, inflation, increases in interest rates, natural disasters, public health crises, political crises, geopolitical events, such as the crisis in Ukraine, or other macroeconomic conditions, which could negatively impact our business and financial performance.
The global economy, including credit and financial markets, has experienced extreme volatility and disruptions, including, among other things, severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, supply chain shortages, increases in inflation rates, higher interest rates and uncertainty about economic stability. For example, the COVID-19 pandemic resulted in widespread unemployment, economic slowdown and extreme volatility in the capital markets. The U.S. Federal Reserve recently raised interest rates multiple times in response to concerns about inflation and it may raise them again. Higher interest rates, coupled with reduced government spending and volatility in financial markets may increase economic uncertainty and affect consumer spending. Similarly, the ongoing military conflict between Russia and Ukraine has created extreme volatility in the global capital markets and is expected to have further global economic consequences, including disruptions of the global supply chain and energy markets. Any such volatility and disruptions may adversely affect our business or the third parties on whom we rely. If the equity and credit markets deteriorate, including as a result of political unrest or war, it may make any necessary debt or equity financing more costly or more dilutive or more difficult to obtain in a timely manner or on favorable terms, if at all. Increased inflation rates can adversely affect us by increasing our costs, including labor and employee benefit costs.
Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards, which could adversely affect the development of our product candidates and our business.
We are exposed to the risk of fraud or other misconduct by our employees, collaborators, principal investigators, consultants, commercial partners and outside actors. Misconduct by these parties could include intentional failures to comply with FDA regulations or the regulations applicable in other jurisdictions, provide accurate information to the FDA and other regulatory authorities, comply with healthcare fraud and abuse laws and regulations in the United States and abroad, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs, and other business arrangements. Such misconduct also could involve the improper use of information obtained during clinical trials or interactions with the FDA or other regulatory authorities, which could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of conduct applicable to all our employees, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, financial condition, results of operations and prospects, including the imposition of significant fines or other sanctions.
If the security of the personal information that we (or our vendors, clinical investigators, CROs, collaborators, contractors, or consultants) collect, store or process is compromised or is otherwise accessed without authorization, or if we fail to comply with our commitments and assurances regarding the privacy and security of such information, our reputation may be harmed and we may be exposed to liability and loss of business.
Our internal computer systems, cloud-based computing services and those of our current and any future vendors, clinical investigators, CROs, collaborators, contractors, or consultants, are vulnerable to damage or interruption from natural disasters, fire, power loss, telecommunications failures, server malfunction, software or hardware failures, traditional computer “hackers,” malicious code (such as viruses and worms), phishing attacks, employee theft or misuse, denial-of-service attacks, adware, malware installation, sophisticated nation-state and nation-state supported actors and other cyberattacks. Cyberattacks and other malicious internet-based activity continue to increase in frequency, sophistication and intensity, and are becoming increasingly difficult to detect.
We have conducted information security audits or evaluations on our internal computer systems, but we cannot guarantee that our or our vendors’, clinical investigators’, CROs’, collaborators’, contractors’, or consultants’ security measures will be sufficient to protect against unauthorized access to, or other compromise of, our systems and our confidential, financial or proprietary data, including personal information, which is stored in or otherwise processed by such systems. Since the COVID-19 pandemic, many of our employees continue to work remotely on a part-time basis, which may pose additional data security risks. While we have security measures in place designed to protect our confidential and proprietary information and prevent data loss and other security breaches, there can be no assurance that our security measures or those of our third-party service providers that store or otherwise process certain of our confidential, financial or proprietary data on our behalf will be effective in protecting against unauthorized access to our platform or such data, particularly given that our ability to monitor our third-party service providers’ data security is limited.
The techniques used to sabotage or to obtain unauthorized access to our or our third party service providers’ platform, systems, networks and/or physical facilities in which data is stored or through which data is transmitted change frequently, may not be recognized until launched, and can originate from a wide variety of sources, and we and our third-party services providers may be unable to implement adequate preventative measures or stop security breaches while they are occurring. The recovery systems, security protocols, network protection mechanisms and other security measures that we have integrated into our platform, systems, networks and physical facilities, which are designed to protect against, detect and minimize security breaches, may not be adequate to prevent or detect service interruption, system failure or data loss. Our platform, systems, networks, and physical facilities could be breached, or confidential or proprietary information could be otherwise compromised due to employee error or malfeasance, third parties may also exploit vulnerabilities in, or obtain unauthorized access to, platforms, systems, networks and/or physical facilities utilized by our third-party service providers.
If a cyberattack or other security incident were to occur and cause interruptions in our operations, it could result in a disruption of our development programs and our business operations, whether due to a loss of our trade secrets or other confidential or proprietary information or other similar disruptions. For example, the loss of clinical trial data could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. The costs to respond to a security breach and/or to mitigate any security vulnerabilities that may be identified could be significant, our efforts to address these issues may not be successful, and these issues could result in interruptions, delays, cessation of service, negative publicity, loss of public trust, delays in the development and commercialization of our product candidates. Any security breach may also result in regulatory inquiries or action, litigation, or other investigations, fines, penalties, and damages, any of which can affect our financial and operational condition.
Failure to prevent or mitigate cyberattacks could result in unauthorized access to our confidential and proprietary data, including personal information. Most jurisdictions have enacted laws requiring companies to notify individuals, regulatory authorities, and others of security breaches involving certain types of data. In addition, our agreements with certain counterparties and partners may require us to notify them in the event of a security breach. Such mandatory disclosures are costly, could lead to negative publicity, may cause the
public to lose confidence in the effectiveness of our security measures and require us to expend significant capital and other resources to respond to and/or alleviate problems caused by an actual or perceived security breach.
Further, security compromises experienced by our collaborators, business partners, patients or employees with respect to data hosted on our platform, internal computer systems, and/or cloud-based computing services, even if caused by third-party misuse or negligence, may lead to loss, unauthorized access, or public disclosures of such data, which could harm our reputation, erode confidence in the effectiveness of our security measures, negatively impact our ability to attract new collaborators or other business relationships, or cause existing contractual counterparties to elect not to renew their agreements with us. Any data breach by service providers that are acting as data processors and processing personal information on our behalf could also mean that we are subject to these fines and must comply with the notification obligations set out above.
Unauthorized access to our platform, systems, networks, or physical facilities could result in litigation with or liabilities to our contractual counterparties or other relevant stakeholders, which may adversely affect our business. While we maintain cybersecurity insurance, we could still be required to spend money in defense or settlement, divert management’s time or attention, fundamentally change our business activities and practices or modify our products and/or platform capabilities, which could have an adverse effect on our business. Litigation could also increase our costs of doing business or adversely affect our reputation.
Our risks are likely to increase as we continue to expand, and process, store, and transmit increasingly large amounts of proprietary and sensitive data.
We may be classified as a passive foreign investment company (PFIC) for U.S. federal income tax purposes, which could result in adverse U.S. federal income tax consequences to U.S. investors in the common shares.
Based on the estimated composition of our income, assets and operations, we do not believe that we were classified as a PFIC for U.S. federal income tax purposes for the taxable year ended December 31, 2022. A non-U.S. company will be considered a PFIC for any taxable year if (i) at least 75% of its gross income is passive income (including interest income), or (ii) at least 50% of the value of its assets (generally based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income. In addition, for purposes of the above calculations, a non-U.S. corporation that directly or indirectly owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets and received directly its proportionate share of the income of such other corporation. The value of our assets generally is determined by reference to the market price of our common shares, which may fluctuate considerably. In addition, the composition of our income and assets is affected by how, and how quickly, we spend the cash we raise. If we were to be treated as a PFIC for any taxable year during which a U.S. Holder (as defined in the section entitled “Material U.S. Federal Income Tax Considerations for U.S. Holders” hereof) held a common share, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder, including (1) the treatment of all or a portion of any gain on disposition of a common share as ordinary income, (2) the application of an interest charge with respect to such gain and certain dividends and (3) compliance with certain reporting requirements. See the section titled “Material U.S. Federal Income Tax Considerations for U.S. Holders.”
There are risks inherent in our business that may subject us to potential product liability suits and other claims, which may require us to engage in expensive and time-consuming litigation or pay substantial damages and may harm our reputation, which could negatively impact our business.
Our business exposes us to product liability risks, which are inherent in the testing, clinical development, manufacturing, marketing and sale of biopharmaceutical products. For example, we may be sued if any product or product candidate we develop allegedly causes or is perceived to cause injury or is found to be otherwise unsuitable during product testing, clinical development, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach or violation of warranties and/or trademarks. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit
commercialization of our products. Even a successful defense would require significant financial and management resources.
Regardless of merit or eventual outcome, product liability or other claims may, among other things, result in:
|●||decreased demand for any approved products;|
|●||injury to our reputation and significant negative media attention;|
|●||withdrawal of clinical trial participants or cancellation of clinical trials;|
|●||costs to defend the related litigation;|
|●||a diversion of management’s time and our resources;|
|●||substantial monetary awards to clinical trial participants or patients;|
|●||regulatory investigations, product recalls, withdrawals or labeling, marketing or promotional restrictions;|
|●||exhaustion of any available insurance and our capital resources;|
|●||loss of revenue;|
|●||a potential decrease in our share price; and|
|●||the inability to commercialize any products we develop.|
Our inability to obtain and maintain sufficient product liability insurance at an acceptable cost and scope of coverage to protect against potential product liability claims could prevent or inhibit the commercialization of our products. We obtained product liability insurance covering our clinical trials with policy limits that we believe are customary for similarly situated companies and adequate to provide us with coverage for foreseeable risks. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Moreover, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If we determine that it is prudent to increase our product liability coverage due to the commercial launch of any approved product, we may be unable to obtain such increased coverage on acceptable terms, or at all. Our insurance policies also have various exclusions and deductibles, and we may be subject to a product liability claim for which we have no coverage. We will have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts.
Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental, health and safety laws and regulations, which can be expensive and restrict or interrupt our business.
Our research and development activities and our third-party manufacturers’ and suppliers’ activities involve the generation, storage, use and disposal of hazardous materials, including the components of our product candidates, such as genetically modified cells, and other hazardous compounds and wastes. We and our manufacturers and suppliers are subject to environmental, health and safety laws and regulations governing, among other matters, the use, manufacture, generation, storage, handling, transportation, discharge and disposal of these hazardous materials and wastes and worker health and safety. In some cases, these hazardous materials and various wastes resulting from their use are stored at our and our manufacturers’ facilities pending their use and disposal. We cannot eliminate the risk of contamination or injury, which could result in an interruption of our commercialization efforts, research and development efforts and business operations, damages and significant cleanup costs and liabilities under applicable environmental, health and safety laws and regulations. We also cannot guarantee that the safety procedures utilized by our third-party manufacturers for handling and disposing of these materials and wastes generally comply with the standards prescribed by these laws and regulations. We may be held liable for any resulting damages costs or liabilities, which could exceed our resources, and state or federal or other applicable authorities may curtail our use of certain materials and/or interrupt our business operations.
Furthermore, environmental, health and safety laws and regulations are complex, change frequently and have tended to become more stringent and enforcement is prioritized. We cannot predict the impact of such changes and cannot be certain of our future compliance. We may be required to incur substantial expenses in connection with current and future environmental, health and/ or safety compliance, in which case, our production and development efforts may be interrupted or delayed and our financial condition and results of operations may be materially adversely affected. Failure to comply with these environmental, health and safety laws and regulations may result in substantial fines, penalties or other sanctions. We do not currently carry hazardous waste insurance coverage.
Risks related to regulatory compliance
The regulatory approval process of the FDA, EMA and other comparable foreign regulatory authorities are lengthy and time-consuming, and we may experience significant delays in the clinical development and regulatory approval of our product candidates.
Of the large number of products in development, only a small percentage successfully complete the FDA, EMA or comparable regulatory authorities’ approval processes and are commercialized. The lengthy approval or marketing authorization process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval or marketing authorization to market LAVA-051, LAVA-1207 or our other or future product candidates, which would significantly harm our business, financial condition, results of operations and prospects.
We may face unforeseen challenges in our product candidate development strategy, and we can provide no assurances that our product candidates or clinical trial design will prove to be effective, that we will be able to take advantage of abbreviated regulatory pathways for any of our product candidates, or that we will ultimately be successful in our future clinical trials. We may request regulatory approval of LAVA-051, LAVA-1207 and future product candidates by target, regardless of cancer type or origin, which the FDA or other regulatory authorities may have difficulty accepting if our clinical trials only involved cancers of certain origins. Accordingly, the regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and approval may not be obtained.
We currently anticipate initially seeking regulatory approvals in the United States and Europe but may in the future submit applications for the regulatory approval of LAVA-051, LAVA-1207 or our product candidates to additional regulatory authorities. It is possible that neither our current product candidates nor any product candidates we may seek to develop in the future will obtain regulatory approval. Neither we nor any of our partners are permitted to market any of our product candidates in the United States or abroad until we receive regulatory approval from the FDA, EMA or the applicable regulatory agency.
We could also encounter delays if our investigators encounter unresolved ethical issues associated with enrolling participants in clinical trials of our product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may ultimately lead to the denial of regulatory approval of our product candidates.
If we are successful in obtaining regulatory approvals for LAVA-051, LAVA-1207 or other product candidates, we will be subject to ongoing regulatory oversight.
Our product candidates, if approved, could be contingent on the performance of costly additional clinical trials, including post-market clinical trials, for a more limited indication or patient population than we originally request, and may not be approved or authorized with the labeling that we believe is necessary or desirable for the successful commercialization of a product candidate. Any delay in obtaining, or inability to obtain, applicable regulatory approval or other marketing authorization would delay or prevent commercialization of that product candidate, which would adversely impact our business and prospects.
We will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record keeping, submission of safety and other post-market information and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirement if LAVA-051, LAVA-1207 or other product candidates are approved. Any regulatory approvals that we receive for our product candidates may also be subject to a Risk Evaluation and Mitigation
Strategy (REMS) to ensure that the benefits of treatment with such product candidate outweigh the risks for each potential patient, which may include, among other things, a communication plan to health care practitioners, patient education, extensive patient monitoring or distribution systems and processes that are highly controlled, restrictive and more costly than what is typical for the industry, We or our collaborators may also be required to engage in similar action such as patient education, certification of health care professionals or specific monitoring. A REMS may also be required to limit the approved indicated uses for which the product candidate may be marketed or to the conditions of approval, or may contain requirements for potentially costly post-marketing testing, including Phase 4 trials, and for surveillance to monitor the quality, safety and efficacy of the product candidate. Such regulatory requirements may differ from country to country depending on where we have received regulatory approval. Compliance with such ongoing regulatory requirements is costly and requires the implementation and maintenance of extensive controls, procedures, and time commitments by our personnel.
If we, or a regulatory authority, discover previously unknown problems with a product candidate, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product candidate is manufactured or if a regulatory authority disagrees with the promotion, marketing or labeling of that product candidate, a regulatory authority may impose restrictions relative to that product candidate, the manufacturing facility or us, including requesting a recall or requiring withdrawal of the product candidate from the market or suspension of manufacturing.
If we fail to comply with applicable regulatory requirements following approval of our product candidates, a regulatory authority may, among other things, issue warning letters or untitled letters, mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners, or require other restrictions on the labeling or marketing of such products, require us to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due dates for specific actions and penalties for noncompliance, seek an injunction or impose administrative, civil or criminal penalties or monetary fines, suspend or modify any ongoing clinical trials, or suspend, modify withdraw regulatory approval or restrict the marketing or manufacturing of the product candidate. If any of the foregoing actions occurs, it would negatively affect our business, financial condition and results of operations.
Moreover, the FDA and other regulatory authorities strictly regulate the promotional claims that may be made about biologic products. In particular, a product may not be promoted for uses that are not approved by the FDA as reflected in the product’s approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant civil, criminal and administrative penalties.
The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad.
Even if a product candidate receives marketing approval, it may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success.
Even if any product candidate receives marketing approval, it may fail to gain market acceptance by physicians, patients, third-party payors and others in the medical community. If any such product candidate does not achieve an adequate level of acceptance, we may not generate significant product revenue and may not become profitable. The degree of market acceptance of any product candidate, if approved for commercial sale, will depend on a number of factors, including but not limited to:
|●||the cost, efficacy, safety profile, convenience, ease of administration and other potential advantages compared to alternative treatments and therapies;|
|●||the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;|
|●||the strength of our relationships with patient communities;|
|●||the availability of third-party coverage and adequate reimbursement and patients’ willingness to pay out-of-pocket in the absence of such coverage and adequate reimbursement;|
|●||the prevalence and severity of any side effects; and|
|●||any restrictions on the use of the product candidate together with other medications.|
Our efforts to educate physicians, patients, third-party payors and others in the medical community on the benefits of our product candidates may require significant resources and may never be successful. Such efforts may require more resources than are typically required due to the complexity and uniqueness of our product candidates. Because we expect sales of our product candidates, if approved, to generate substantially all of our revenues for the foreseeable future, the failure of our product candidates to find market acceptance would harm our business.
We have sought and may continue to seek orphan drug designation for some or all of our current or future product candidates and may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for supplemental market exclusivity.
Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs or biologics for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States when there is no reasonable expectation that the cost of developing and making available the drug in the United States will be recovered from sales in the United States for that drug. The criteria for designating an “orphan medicinal product” in the European Union are similar in principle to those in the United States. Regulation (EC) No. 141/2000 and Regulation (EC) No. 847/2000 provide that a product can be designated as an orphan drug by the European Commission if its sponsor can establish: that the product is intended for the diagnosis, prevention or treatment of (1) a life-threatening or chronically debilitating condition affecting not more than five in ten thousand persons in the European Union when the application is made, or (2) a life-threatening, seriously debilitating or serious and chronic condition in the European Union and that without incentives it is unlikely that the marketing of the drug in the European Union would generate sufficient return to justify the necessary investment.
Orphan medicinal product status in the European Union can provide up to 10 years of marketing exclusivity, meaning that another application for marketing authorization of a later similar medicinal product for the same therapeutic indication will generally not be approved in the European Union. Although we may have drug candidates that may obtain orphan drug exclusivity in Europe, the orphan approval and associated exclusivity period may be modified for several reasons, including a significant change to the orphan medicinal product designations or approval criteria after-market authorization of the orphan product (e.g., product profitability exceeds the criteria for orphan drug designation), problems with the production or supply of the orphan drug or a competitor drug, although similar, is safer, more effective or otherwise clinically superior than the initial orphan drug.
If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a BLA, to market the same product for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. As a result, even if one of our product candidates receives orphan exclusivity, the FDA can still approve other products that have a different active ingredient for use in treating the same indication or disease. Further, the FDA can waive orphan exclusivity if we are unable to manufacture sufficient supply of our product.
We received orphan drug designation for LAVA-051 for CLL and may seek orphan drug designation for our other indications for LAVA-051 or other current or future product candidates. Even when we obtain orphan drug designation, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the
request for designation was materially defective or if we, through our manufacturer, are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. In addition, although we intend to seek orphan drug designation for other product candidates, we may never receive these designations.
We may not elect or be able to take advantage of any expedited development or regulatory review and approval processes available to product candidates granted breakthrough therapy or fast track designation by the FDA.
We intend to evaluate and engage in discussions with the FDA on regulatory strategies that could enable us to take advantage of expedited development pathways for our current product candidates or future product candidates, although we cannot be certain that any such products will qualify for any expedited development pathways or that regulatory authorities will grant, or allow us to maintain, the relevant qualifying designations. Potential expedited development pathways that we could pursue include breakthrough therapy and fast track designation.
Breakthrough therapy designation is intended to expedite the development and review of products that treat serious or life-threatening diseases when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation of a product candidate as a breakthrough therapy provides potential benefits that include intensive guidance on an efficient drug development program, beginning as early as Phase 1, organizational commitment involving senior managers; and eligibility for rolling review and priority review. Breakthrough therapy designation does not change the standards for product approval. There can be no assurance that we will receive breakthrough therapy designation for any product candidate or any particular indication.
We may also seek fast track designation. If a drug or biologic candidate is intended for the treatment of a serious or life-threatening condition or disease and the drug demonstrates the potential to address unmet medical needs for the condition, the sponsor may apply for fast-track designation. Even if we do apply for and receive fast track designation, we may not experience a faster development, review or approval process compared to conventional FDA procedures. The FDA may rescind fast track designation if it believes that the designation is no longer supported by data from our clinical development program.
Additionally, we may also seek accelerated approval under the FDA’s accelerated approval programs. The FDA may approve a drug or biologic for a serious or life-threatening disease or condition that generally provides meaningful advantages over available treatments and demonstrates an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments.
Seeking and obtaining these designations is dependent upon results of our clinical program, and we cannot guarantee whether and when we may have the data from our clinical programs to support an application to obtain any such designation. The FDA and comparable foreign regulatory agencies have broad discretion whether to grant any of these or similar designations, so even if we believe a particular product candidate is eligible for one or more of these designations, we cannot assure you that the applicable regulatory authority would decide to grant it. Even if we do receive the designations we may apply for, we may not experience a faster development process, review or approval compared to conventional procedures, as applicable. The FDA or other regulatory agencies may also rescind any granted designations if it believes that the designation is no longer supported by data from our clinical development program.
We expect the product candidates we develop will be regulated as biologics, and therefore they may be subject to competition sooner than anticipated.
The Biologics Price Competition and Innovation Act of 2009 (BPCIA) was enacted as part of the Affordable Care Act to establish an abbreviated pathway for the approval of biosimilar and interchangeable biological products. The regulatory pathway establishes legal authority for the FDA to review and approve biosimilar
biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an approved biologic. Under the BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after the reference product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when processes intended to implement BPCIA may be fully adopted by the FDA, any of these processes could have a material adverse effect on the future commercial prospects for our biological products.
We believe that any of the product candidates we develop that is approved in the United States as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider the subject product candidates to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of the reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.
In addition, the approval of a biologic product biosimilar to one of our products could have a material adverse impact on our business as it may be significantly less costly to bring to market and may be priced significantly lower than our products.
Our relationships with customers, physicians, and third-party payors will be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, including anti-kickback and false claims laws, transparency laws, local and foreign environmental and safety laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
Healthcare providers, including physicians, and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, principal investigators, consultants, customers and third-party payors subject us to various federal and state fraud and abuse laws and other healthcare laws, including, without limitation, the federal Anti-Kickback Statute, the federal civil and criminal false claims laws and the law commonly referred to as the Physician Payments Sunshine Act and regulations. For additional information on the healthcare laws and regulations that we may be subject to, see section titled “Information about the Company—Government Regulation.”
Ensuring that our business arrangements with third parties comply with applicable healthcare laws and regulations will likely be costly. It is possible that governmental authorities will conclude that our business practices, including our relationships with physicians, some of whom are compensated with a stipend or share options for services performed for the Company, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government-funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, reputational harm and the curtailment or restructuring of our operations. If the physicians or other providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may be subject to significant criminal, civil or administrative sanctions, including exclusions from government-funded healthcare programs.
Coverage and adequate reimbursement may not be available for our product candidates, which could make it difficult for us to sell profitably, if approved.
Market acceptance and sales of any product candidates that we commercialize, if approved, will depend in part on the extent to which reimbursement for these products and related treatments will be available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers. Third-party payors decide which therapies they will pay for and establish
reimbursement levels. While no uniform policy for coverage and reimbursement exists in the United States, third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for any product candidates that we develop will be made on a payor-by-payor basis. Therefore, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. Additionally, we or our collaborators may develop companion diagnostic tests for use with our product candidates. We or our collaborators will be required to obtain coverage and reimbursement for these tests separate and apart from the coverage and reimbursement we seek for our other product candidates, once approved.
Healthcare legislative reform measures may have a negative impact on our business and results of operations.
In the United States and some foreign jurisdictions, there have been, and continue to be, legislative and regulatory changes to the healthcare delivery and reimbursement system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval. There have been and continue to be a number of initiatives at the federal and state levels in the United States that seek to reduce healthcare costs and improve the quality of healthcare.
For example, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, or, collectively, the ACA, substantially changed the way healthcare is financed by both governmental and private payors in the United States and increased access to health care coverage for individuals. Since its enactment, there have been executive, judicial and Congressional challenges to the ACA. Most of the ACA survived such challenges but further healthcare reform measures of the Biden administration may impact the ACA or our business. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (IRA) into law, which, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. We continue to evaluate the effect that changes to the ACA and other reforms may have on our business. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.
Other legislative changes have been adopted since the ACA was enacted. These changes include, among other things, aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, including the BBA, which will remain in effect through 2030 unless additional Congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 4% in the final fiscal year of this sequester. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.
Additional changes that may affect our business include the expansion of new programs such as Medicare payment for performance initiatives for physicians under the Medicare Access and CHIP Reauthorization Act of 2015. At this time, it is unclear how the introduction of the Medicare quality payment program will impact overall physician reimbursement.
Further, in the United States there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under government payor programs, and review the relationship between pricing and manufacturer patient programs. For example, the Biden administration announced its intention to pursue certain priority policy initiatives, such as the reduction of
prescription drug pricing, including legislative proposals to allow the government to negotiate drug prices for Medicare and other governmental health programs, increasing access and coverage for mental health, and lower nursing home care costs. In addition, the IRA, among other things, (i) directs the U.S. Department of Health and Human Services (HHS), to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions will take effect progressively starting in fiscal year 2023, although they may be subject to legal challenges.
It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. Further, the Biden administration released an additional executive order on October 14, 2022, directing HHS to submit a report on how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for lowering drug costs for Medicare and Medicaid beneficiaries. It is unclear whether this executive order or similar policy initiatives will be implemented in the future. We expect that additional U.S. federal healthcare reform measures to be adopted in the future, could limit the amounts that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand for our current or any future product candidates or additional pricing pressures. If we or any third parties we may engage are slow or unable to adapt to changes in existing or new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our current or any future product candidates we may develop may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.
Further, any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products. For additional information on healthcare reform, see the section titled “Information about the Company—Government Regulation and Product Approval.”
In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize current or any future product candidates, if approved. In addition to continuing pressure on prices and cost containment measures, legislative developments at the EU or member state level may result in significant additional requirements or obstacles that may increase our operating costs. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, U.S. federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.
European drug marketing and reimbursement regulations may materially affect our ability to market and receive coverage for our products in the European member states.
We intend to seek approval to market our product candidate in the United States as well as select foreign jurisdictions. If we obtain approval in one or more foreign jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. In some foreign countries, particularly those in Europe, the pricing of biologics is subject to governmental control and other market regulations which could put pressure on the pricing and usage of our product candidate. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. In addition, market acceptance and sales of our product candidate will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our product candidate and may be affected by existing and future health care reform measures.
Much like the Anti-Kickback Statue prohibition in the United States, the provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is also prohibited in Europe. The provision of benefits or advantages to physicians is governed by the national anti-bribery laws of European Union member states. Infringement of these laws could result in substantial fines and imprisonment.
Payments made to physicians in certain European Union member states must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual European Union member states. These requirements are provided in the national laws, industry codes or professional codes of conduct, applicable in the European Union Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.
In addition, in most foreign countries, including in Europe, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing and reimbursement vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. Reference pricing used by various European Union member states and parallel distribution, or arbitrage between low-priced and high-priced member states, can further reduce prices. A member state may approve a specific price for the medicinal product, or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. In some countries, we may be required to conduct a clinical study or other studies that compare the cost-effectiveness of our product candidate to other available therapies to obtain or maintain reimbursement or pricing approval. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for our product. Historically, products launched in the European Union do not follow price structures of the United States and generally prices tend to be significantly lower. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If pricing is set at unsatisfactory levels or if reimbursement of our products is unavailable or limited in scope or amount, our revenues from sales by us or our strategic partners and the potential profitability of our product candidate in those countries would be negatively affected.
We are subject to stringent and changing laws, regulations and standards, and contractual obligations related to data privacy and security. The actual or perceived failure to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations, and financial condition.
Data privacy and security has become a significant focus in the United States and abroad. The regulatory framework for privacy issues is rapidly evolving and is likely to remain uncertain for the foreseeable future. Many government bodies and agencies have adopted or are considering adopting laws and regulations regarding the collection, use, processing, storage, transmission, destruction, and disclosure of personal information and breach notification procedures. We are also required to comply with laws, rules and regulations relating to data security. Interpretation of these laws, rules and regulations in applicable jurisdictions is ongoing and cannot be fully determined at this time.
In the United States, there are state and federal laws relating to data privacy and security. As we expand our operations, these laws which vary from jurisdiction to jurisdiction, may increase our compliance costs and potential liability. In addition to California, Virginia and Maine, other states are beginning to propose similar laws, which may be the beginning of a trend toward more stringent privacy legislation in the United States that could increase our potential liability and adversely affect our business, results of operations and financial condition.
Compliance with these and any other applicable privacy and data security laws and regulations is a rigorous and time-intensive process, and we may be required to put in place additional mechanisms to ensure compliance with these and new data protection rules. If we fail to comply with any such laws or regulations,
we may face significant fines and penalties that could adversely affect our business, financial condition and results of operations.
European data protection laws including the General Data Protection Regulation (GDPR) also generally prohibit the transfer of personal information from Europe to the United States and most other non-European Economic Area countries unless the parties to the transfer have implemented specific safeguards to protect the transferred personal information. There is uncertainty regarding how to ensure that transfers of personal information from Europe to the United States comply with the GDPR. As such, any transfers by us, or our vendors, of personal information from Europe may not comply with European data protection laws; may increase our exposure to the GDPR’s heightened sanctions for violations of its cross-border data transfer restrictions; and may reduce demand for our services from companies subject to European data protection laws. Loss of our ability to transfer personal information from Europe may also require us to increase our data processing capabilities in those jurisdictions at significant expense.
As a result of our clinical development, we, our clinical investigators, CROs and consultants may have access to very sensitive data regarding the patients enrolled in our clinical trials, and our current and future product candidates will rely on the use of patient and donor data and material. This data will contain information that is personal in nature, and the maintenance of this data is subject to certain privacy-related laws, such as GDPR, the U.S. Health Insurance Portability and Accountability Act (HIPAA), as amended by the Health Information Technology for Economic and Clinical Health Act and U.S. state privacy laws. These rules inter alia require that written authorizations from patients are obtained and that policies, procedures and reasonable and appropriate security measures are implemented that protect individually identifiable health and other information we receive and to ensure that such information is used only as authorized by the patient. If the patient fails to execute an authorization or the authorization fails to contain all required provisions, then we will not be allowed access to the patient’s information and our research efforts can be substantially delayed. Also, any violations of these rules by us could subject us to civil and criminal penalties and adverse publicity and could harm our ability to initiate and complete clinical trials.
Complying with the GDPR and other related foreign privacy laws and regulations may cause us to incur substantial operational costs or require us to change our business practices. Despite our efforts to bring our practices into compliance with these laws and regulations, we may not be successful in our efforts to achieve compliance either due to internal or external factors such as resource allocation limitations or a lack of vendor cooperation. Any inability to adequately address privacy concerns, even if unfounded, or comply with applicable privacy or data protection laws, regulations and policies, could result in additional cost and liability to us, damage our reputation, inhibit sales and adversely affect our business, results of operations and financial condition.
We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal or civil liability and harm our business.
We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended (FCPA) the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We interact with officials and employees of government agencies and government-affiliated hospitals, universities and other organizations. In addition, we may engage third-party intermediaries to promote our clinical research activities abroad or to obtain necessary permits, licenses and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize or have actual knowledge of such activities.
We adopted a Code of Business Conduct and Ethics and implemented policies and procedures to ensure compliance with such code. The Code of Business Conduct and Ethics mandates compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, we cannot be
assured that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas, investigations or other enforcement actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens.
Further downgrades of the U.S. credit rating, automatic spending cuts, or another government shutdown could negatively impact our liquidity, financial condition and earnings.
U.S. debt ceiling and budget deficit concerns have increased the possibility of additional credit-rating downgrades and economic slowdowns, or a recession in the United States. Although U.S. lawmakers have previously passed legislation to raise the federal debt ceiling on multiple occasions, ratings agencies have lowered or threatened to lower the long-term sovereign credit rating on the United States. The impact of this or any further downgrades to the U.S. government’s sovereign credit rating or its perceived creditworthiness could adversely affect the U.S. and global financial markets and economic conditions. Moreover, absent further quantitative easing by the Federal Reserve, these developments could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the U.S. debt markets on favorable terms. In addition, disagreement over the federal budget has caused the U.S. federal government to shut down for periods of time. Continued adverse political and economic conditions could have a material adverse effect on our business, financial condition and results of operations.
Risks related to ownership of our common shares
The market price of our common shares has been, and may continue to be volatile and fluctuate substantially, and you could lose all or part of your investment and may subject us to securities litigation suits.
The market price of our common shares is volatile. The stock market in general and the market for biopharmaceutical and pharmaceutical companies in particular, has experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, holders of our common shares may lose all or part of their investment. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this annual report, the market price for our common shares may be influenced by, among others, the following:
|●||the enrollment or results of our clinical trials for LAVA-051 or LAVA-1207 and the commencement of enrollment or results of our other or future product candidates or those of our competitors;|
|●||the success of competitive products or therapies or announcements by potential competitors of their product development efforts;|
|●||regulatory or legal developments in the United States, the Netherlands, Europe more broadly and other jurisdictions;|
|●||developments or disputes concerning patent applications, issued patents or other proprietary rights;|
|●||actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;|
|●||disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies;|
|●||significant lawsuits, including patent or shareholder litigation;|
|●||market volatility due to the continued effects of and responses to the COVID-19 pandemic;|
|●||share price and volume fluctuations attributable to inconsistent trading volume levels of our common shares;|
|●||announcement or expectation of additional financing efforts or sales by our shareholders;|
|●||general economic, political, and market conditions and overall fluctuations in the financial markets in the United States, Europe and elsewhere;|
|●||changes in the structure of healthcare payment systems; and|
|●||investors’ general perception of us and our business.|
In addition, some companies that have experienced volatility in the trading price of their shares have been the subject of securities class action litigation. Any lawsuit to which we are a party, with or without merit, may result in an unfavorable judgment. We also may decide to settle lawsuits on unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our business practices. Defending against litigation is costly and time-consuming and could divert our management’s attention and our resources. Furthermore, during litigation, there could be negative public announcements of the results of hearings, motions or other interim proceedings or developments, which could have a negative effect on the market price of our common shares.
Investors may have difficulty enforcing civil liabilities against us or the members of our board of directors and our senior management.
We are incorporated under the laws of the Netherlands and substantially all our assets are located outside the United States.
As a result, it may not be possible for shareholders to effect service of process within the United States upon us or our directors and executive officers or to enforce judgments against us or them in U.S. courts, including judgments predicated upon the civil liability provisions of the federal securities laws of the United States. In addition, it is not clear whether a Dutch court would impose civil liability on us or any of our directors and executive officers in an original action based solely upon the federal securities laws of the United States brought in a court of competent jurisdiction in the Netherlands.
As of the date of this annual report, the United States and the Netherlands do not have a treaty providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. The Hague Convention on Choice of Court Agreements of June 30, 2005, is currently in force in the Netherlands, but not in the United States. The Hague Convention of July 2, 2019, on the Recognition and Enforcement of Foreign Judgments in Civil or Commercial Matters has not entered into force for either the Netherlands or the United States. Accordingly, a judgment rendered by a court in the United States, regardless of whether it is predicated solely upon U.S. securities laws, would not automatically be recognized and enforced by the competent Dutch courts. However, if a person has obtained a judgment rendered by a court in the United States that is enforceable under the laws of the United States and files a claim with the competent Dutch court, the Dutch court will in principle give binding effect to such judgment if (i) the jurisdiction of the U.S. court was based on a ground of jurisdiction that is generally acceptable according to international standards, (ii) the judgment by the U.S. court was rendered in legal proceedings that comply with the Dutch standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging), (iii) binding effect of such U.S. judgment is not contrary to Dutch public order (openbare orde) and (iv) the judgment by the U.S. court is not incompatible with a decision rendered between the same parties by a Dutch court, or with a previous decision rendered between the same parties by a U.S. court in a dispute that concerns the same subject and is based on the same cause, provided that the previous decision qualifies for recognition in the Netherlands. Even if such a U.S. judgment is given binding effect, a claim based thereon may, however, still be rejected if the U.S. judgment is not or no longer formally enforceable.
Consequently, U.S. investors may not be able to enforce against us or our directors, representatives or certain experts named herein who are residents of the Netherlands or countries other than the United States
any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.
Shareholders may not be able to exercise pre-emption rights and, as a result, may experience substantial dilution upon future issuances of common shares or grants of rights to subscribe for shares.
In the event of an issuance of common shares or a grant of rights to subscribe for common shares, subject to certain exceptions, each shareholder will have a pro rata pre-emption right in proportion to the aggregate nominal value of such holder’s common shares. These pre-emption rights may be restricted or excluded by a resolution of the general meeting or by another corporate body designated by the general meeting. Our board of directors has been authorized until March 2026 to issue shares or grant rights to subscribe for shares up to our authorized share capital from time to time and to limit or prohibit pre-emption rights, the issuance of common shares or other equity securities could cause existing shareholders to experience substantial dilution.
Concentration of ownership of our common shares among our existing executive officers, directors and principal shareholders may prevent new investors from influencing significant corporate decisions.
Our executive officers, directors and shareholders who own more than 5% of our outstanding common shares as of February 28, 2023, in the aggregate, beneficially own shares representing approximately 75.0% of our outstanding common shares. If our executive officers, directors and shareholders who own more than 5% of our outstanding common shares acted together, they may be able to significantly influence all matters requiring shareholder approval, including the election and removal of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. The concentration of voting power and transfer restrictions could delay or prevent an acquisition of our company on terms that other shareholders may desire or result in the management of our company in ways with which other shareholders disagree.
We will need to raise additional capital, which may not be available on acceptable terms, or at all. Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our product candidates.
Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through public or private equity or debt financings, third-party funding, marketing and distribution arrangements, as well as other collaborations, strategic alliances and licensing arrangements, or any combination of these approaches. We do not have any committed external source of funds. To the extent that we raise additional capital, if available, through the sale of equity or convertible debt securities, your ownership interest in our company may be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt and equity financings, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as redeeming our shares, making investments, incurring additional debt, making capital expenditures, declaring dividends or placing limitations on our ability to acquire, sell or license intellectual property rights. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our common shares to decline and existing stockholders may not agree with our financing plans or the terms of such financings. Adequate additional financing may not be available to us on acceptable terms, or at all.
If we raise additional capital through future collaborations, strategic alliances or third-party licensing arrangements, we may have to relinquish valuable rights to our intellectual property, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us, if at all. If we are unable to raise additional capital when needed, we may be required to delay, limit, reduce or terminate our product candidate development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise develop and market ourselves.
We incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.
We are an emerging growth company (EGC), as defined in the Jumpstart Our Business Startups Act of 2012. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including an exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act; and to the extent that we no longer qualify as a foreign private issuer, (a) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and (b) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation, including golden parachute compensation. We cannot predict whether investors will find our common shares less attractive if we rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and our share price may be reduced or more volatile.
As a public company, and particularly after we are no longer an EGC or eligible to elect to be treated as a smaller reporting company, we may incur additional legal, accounting and other expenses. The Sarbanes-Oxley Act, and rules subsequently implemented by the U.S. Securities and Exchange Commission (SEC), The Nasdaq Stock Market LLC (Nasdaq), the Dutch Civil Code (DCC) and the Dutch Corporate Governance Code (DCGC) impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. In addition, our management and other personnel need to devote a substantial amount of time to comply with these requirements. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly.
We are subject to Section 404 of the Sarbanes-Oxley Act (Section 404) and are required to furnish a report by our management on our internal control over financial reporting. Once we are no longer an EGC, we will also be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. We would cease to be an EGC upon the earliest to occur of (i) the last day of the fiscal year in which we have more than $1.235 billion in annual gross revenues; (ii) the date we qualify as a “large accelerated filer,” with at least $700.0 million of equity securities held by non-affiliates; (iii) the issuance, in any three-year period, by our Company of more than $1.0 billion in nonconvertible debt securities held by non-affiliates; and (iv) December 31, 2026. To achieve compliance with Section 404 within the prescribed period, we have engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, hire additional qualified accounting personnel, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that neither we nor our independent registered public accounting firm will be able to conclude within the prescribed timeframe that our internal control over financial reporting is effective as required by Section 404. This could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.
Pursuant to the DCC, Dutch limited liability companies may qualify as a so-called structure company (structuurvennootschap) to which the structure regime (structuurregime) is applicable. Currently, the requirements to qualify as such are that a company has filed a statement with the trade register of the Dutch Chamber of Commerce, for a consecutive period of three years, that it meets the following criteria (i) according to our balance sheet with explanatory notes, our issued share capital together with our reserves amounts to at least Euro (EUR) 16 million, (ii) we, or any of our dependent companies (as defined by Dutch law), has established a Dutch works council pursuant to statutory requirements under Dutch law and (iii) we and our dependent companies (as defined by Dutch law) together regularly employ at least 100 employees in the Netherlands. The qualification as a structure company may affect the governance structure of our company. Among other things, our executive directors would then be appointed by our non-executive directors (instead of the general meeting) and certain nomination rights (including for the Dutch works council)
would apply to the appointment of our non-executive directors. We have never filed a statement that we meet the criteria of the structure regime and do not expect to qualify as a structure company for at least the next three years.
We have identified material weaknesses in our internal control over financial reporting. If we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common shares.
Although we are not yet subject to the auditor attestation requirement of Section 404 of the Sarbanes-Oxley Act, our management is responsible for designing, establishing and maintaining internal control over financial reporting. In connection with the preparation of our financial statements as of and for the year ended December 31, 2022, we identified control deficiencies that we concluded represented material weaknesses in our internal control over financial reporting across the principles for each component of the Committee of Sponsoring Organizations of the Treadway Commission (COSO) 2013 framework at the entity level (i.e., control environment, risk assessment, monitoring, information & communication and control activities) and accordingly, across our business and IT processes. The material weaknesses that we identified related to:
|●||the lack of consistent and documented risk assessment procedures and control activities related to our financial reporting, among which are a sufficient level of management review and approval, manual processes, roles and responsibilities, and adequate application and controls over information technology; and|
|●||our ability to: (i) design and maintain formal accounting policies, procedures and controls over the fair presentation of our financial statements; and (ii) design and maintain controls over the preparation and review of journal entries and financial statements, including maintaining appropriate segregation of duties.|
While we have taken measures during the years ended December 31, 2022 and 2021 to remediate these material weaknesses, and we have continued to enhance our internal control over financial reporting for the year ended December 31, 2022, the weaknesses discussed above will not be considered remediated until the appliable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. As such, we cannot consider these material weaknesses as remediated as of December 31, 2022.
We may discover additional weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our consolidated financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.
If we are unable to maintain proper and effective internal controls over financial reporting, or identify any material weakness, we may not be able to produce timely and accurate financial statements which could result in material misstatements in our financial statements and potentially require us to restate our financial statements. If we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, when required, our investors could lose confidence in the accuracy and completeness of our reported financial information, the market price of our shares could be materially adversely affected, we could face restricted access to the capital markets, and we could be subject to sanctions or investigations by the SEC or other regulatory authorities.
While we have begun taking measures and plan to continue to take measures to design and implement an effective control environment, we cannot assure you that the measures we have taken to date, and are continuing to implement, will be sufficient to remediate past or prevent future material weaknesses.
See “Item 15. Controls and Procedures—B. Management’s Annual Report on Internal Control over Financial Reporting” for additional information regarding these material weaknesses.
As a foreign private issuer, we are permitted to, and do, follow certain home country corporate governance practices instead of otherwise applicable Nasdaq requirements, and we will not be subject to certain U.S. securities laws including, but not limited to, U.S. proxy rules and the filing of certain Exchange Act reports. If we lose our status as a foreign private issuer, additional reporting obligations may apply.
As a foreign private issuer (FPI) we are permitted to, and do, follow certain home country corporate governance practices instead of those otherwise required by Nasdaq for domestic U.S. issuers. Following our home country governance practices as opposed to the requirements that would otherwise apply to a U.S. company listed on Nasdaq may provide less protection to you than what is accorded to investors under the listing rules of Nasdaq applicable to domestic U.S. issuers.
As an FPI, we are exempt from the rules and regulations under the Securities Exchange Act of 1934, as amended, or the Exchange Act, related to the furnishing and content of proxy statements, including the applicable compensation disclosure requirements. Our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file reports and financial statements with the SEC as frequently or as promptly as U.S. domestic companies whose securities are registered under the Exchange Act and we are exempt from filing quarterly reports with the SEC under the Exchange Act. Moreover, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information, although we have voluntarily adopted a corporate disclosure policy substantially similar to Regulation FD. These exemptions and leniencies reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to a U.S. domestic issuer.
We would lose our foreign private issuer status if a majority of our shares are owned by U.S. residents and a majority of our directors or executive officers are U.S. citizens or residents or we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher, including filing more detailed and extensive periodic reports and registration statements on U.S. domestic issuer forms with the SEC, convert to accounting principles generally accepted in the U.S. (U.S. GAAP) and modify certain of our policies to comply with accepted governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we would lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to FPIs.

B. Business overview
We are a clinical-stage immuno-oncology company focused on developing our proprietary Gammabody platform of bispecific gamma-delta T cell engagers to transform the treatment of cancer. Using our Gammabody platform, we are developing a portfolio of novel bispecific antibodies designed to engage and leverage the potency and precision of gamma delta (gd) T cells to elicit a robust, anti-tumor immune response and improve outcomes for cancer patients.
Gamma Delta T Cells
Gamma delta (gd) T cells are a “ready-to-fight” first line of defense of the human body and form a bridge between the innate and adaptive immune systems. Vgamma9 Vdelta2 (Vg9Vd2) T cells, the largest subpopulation of gamma delta T cells in healthy adults, are a homogeneous effector T cell population whose prevalence has been correlated with favorable outcomes and survival in blood cancers (hematological malignancies) and solid tumors. They have the natural ability to distinguish cancer cells from healthy cells and, once activated, have the potential to trigger a rapid and potent immune response to a wide array of cancers. In addition, gamma delta T cells can initiate further activation of cells from both the innate and adaptive immune systems, which can lead to a long-lasting immune response and immunological memory.
Other T cell engager (TCE) approaches, including bispecific antibodies that activate T cells through binding of CD3, which is present on all T cells, and adoptive transfer of T cells expressing an engineered chimeric antigen receptor (CAR-T) cells, have provided clinical activity against selected cancers. Nonetheless, the promise of TCEs for broader use as cancer therapy has not yet been fully realized. Drawbacks of these approaches include dose-limiting toxicities resulting from the excessive release of cytokines, referred to as cytokine release syndrome (CRS). CD3-based TCEs have additional limitations because of their indiscriminate activation of T cells, including both effector T cells and regulatory cells (Tregs). Activation of Tregs can dampen anti-cancer immunity, potentially resulting in decreased or no therapeutic efficacy. The therapeutic active dose and the toxic dose of CD3-based TCEs are often in close proximity, resulting in a narrow therapeutic window which may preclude full exploitation of their therapeutic potential. Adoptive transfer of CAR-T cells is complex and costly and has also been associated with significant risk of CRS and on-target off-tumor-related toxicities.
Our Proprietary Gammabody Platform
Our Gammabody platform enables us to develop off-the-shelf bispecific T cell engagers that leverage the advantages of antibody-based treatments including favorable manufacturability and developability characteristics. Our Gammabody platform is designed to recruit the body’s own Vg9Vd2T cells resulting in tumor cell targeting and conditional cancer cell killing. One arm of the Gammabody recruits Vg9Vd2 T cells, while the other arm recognizes and binds to a specific tumor target present on blood cancers or solid tumors. Our Gammabody drug candidates are designed to activate the Vg9Vd2 T cells once the respective arms are bound to the gamma delta T cell and the tumor target thereby avoiding broad systemic activation. We believe this approach provides a significant opportunity to address unmet medical needs with the potential to elicit potent and durable responses in patients. We also believe this approach may provide a superior therapeutic window compared to other approaches by reducing the risk of on target/off tumor mediated toxicity and avoid activation of Tregs and broad systemic activation resulting in CRS.
We have generated compelling preclinical data using patient tumor tissues that demonstrate the ability of our Gammabody platform to exert preferential activity against tumor cells expressing the target with relative sparing of healthy cells. Studies in non-human primates, using surrogate Gammabody molecules, showed that our gamma delta T cell engagers were well tolerated and did not induce high-grade CRS.
As of the date of this Annual Report, we have activated fifteen clinical trial sites in North America and Europe, most of which are actively enrolling patients for our open-label Phase 1/2a clinical trial of LAVA-051 as a monotherapy. We have generated preliminary clinical data for LAVA-051 and presented clinical pharmacokinetic and pharmacodynamic data from the first five patient cohorts of the Phase 1 dose-escalation study that suggest a favorable safety profile, which allowed us to expand the enrollment of patients into planned additional schedules. LAVA-051 showed predictable and linear pharmacokinetics and on-mechanism pharmacodynamic parameters. We expect to report additional safety and efficacy data for the dose escalation phase of the trial when it is available, which may inform the design, including targeted populations, of a future pivotal trial.
As of the date of this Annual Report, we have activated eight clinical trial sites for the ongoing Phase 1/2a clinical trial of LAVA-1207 in North America and Europe, which are actively recruiting. We observed initial signs of biological activity in the first five cohorts and a favorable safety profile, which allowed us to continue enrollment of patients into planned additional cohorts. LAVA-1207 showed predictable and linear pharmacokinetics and on-mechanism pharmacodynamics. Preliminary signs of anti-tumor activity were observed at week 8, with iRECIST stable disease (iSD) in 8 out of 14 evaluable patients and PSA levels stabilizing or decreasing in several patients. We expect to report additional safety and efficacy data for the dose escalation phase of the trial when it is available, which may inform the design of a future pivotal trial.
We believe our Gammabody platform has the potential to develop treatments for patients with a wide variety of cancers, both as monotherapy and in combination with other therapies. Our lead clinical-stage candidates, LAVA-051 and LAVA-1207, are in Phase 1/2a clinical trials for blood cancers and prostate cancer, respectively. LAVA-051 is a Gammabody designed to target CD1d-expressing blood cancers, including CLL, MM and AML. LAVA-1207 is a Gammabody designed to target prostate-specific membrane antigen (PSMA)-expressing cancers. We are developing LAVA-1207 in mCRPC. We are also developing other Gammabody drug candidates, including LAVA-1266, which targets CD123 for the treatment of hematological malignancies. In September 2022, we licensed our advanced preclinical candidate SGN-EGFRd2 (LAVA-1223), which targets EGFR-expressing solid tumors to Seagen Inc. for further development, manufacturing, and if approved, commercialization. We designed our Gammabody platform to be fully modular and compatible with existing anti-tumor antibodies to facilitate expedited discovery and development of novel compounds. We are currently advancing our Gammabody pipeline for the development of potential therapeutics in both hematologic malignancies and solid tumors.
Our most advanced product candidate, LAVA-051, is a unique CD1d-targeting Gammabody in development for treating hematologic cancers including CLL, MM and AML. CD1d is expressed by tumor cells of most patients with CLL, MM and (myelo)monocytic subtypes of AML. LAVA-051 works via a dual mechanism of action, with engagement of Vg9Vd2 T cells as the primary mechanism and is designed to kill CD1d-expressing tumor cells.
LAVA-051 cross-links CD1d-expressing tumor cells and Vg9Vd2 T cells, resulting in conditional Vg9Vd2 T cell activation, the secretion of cytolytic molecules and cytokines and subsequent tumor cell killing. As published in 2020 in Nature Cancer, we preclinically demonstrated that the CD1d-binding moiety of the bsTCE is also uniquely able to enhance the interaction of CD1d and the T cell receptor of invariant NKT cells (iNKT) cells. These iNKT cells are a population of innate-like lymphocytes that play an important role in orchestrating immune responses in cancer. We found that this feature led to iNKT cell activation and anti-tumor activity by LAVA-051. LAVA-051 has shown activity against CD1d-positive CLL, MM and AML cells in in vitro functional assays. These results suggest that LAVA-051 may have a positive effect on clinical outcomes for patients with CLL, MM and AML. We believe the combined Vg9Vd2 T cell and iNKT cell-activating properties and the resulting cascade response of downstream immune cell activation contribute to the potential of LAVA-051 to provide rapid tumor cell cytotoxicity as well as potentially long-term anti-tumor immune responses.
In 2021, we dosed the first patient in a Phase 1/2a clinical trial evaluating LAVA-051 in patients with relapsed or refractory CLL and MM. Patients with AML are expected to be included later in the trial once biologically relevant dosing has been reached. The open-label, multi-center clinical trial will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and preliminary anti-tumor activity of LAVA-051. The Phase 1 dose-escalation study will determine an optimal Phase 2 dose of LAVA-051. The Phase 2a portion of the study will enroll patients in disease-specific cohorts to confirm safety and evaluate preliminary anti-tumor activity in each disease cohort. The Phase 1/2a clinical trial for LAVA-051 has fifteen clinical trial sites in Europe and in the United States. In 2021, the FDA granted orphan drug designation for LAVA-051 for the treatment of CLL.
In December 2022, at the 64th American Society of Hematology Annual Meeting and Exposition (ASH), we reported initial clinical data from the first five patient cohorts of the Phase 1 dose-escalation study. These data suggest potential signs of clinical activity as well as predictable and linear PK and on-mechanism PD parameters consistent with Vg9Vd2 engagement. Drug exposure and (Vg9Vd2) T cell receptor occupancy of LAVA-051 increased with LAVA-051 dose increases and peripheral blood Vg9Vd2 T cells expressed increased levels of activation markers after dosing. One CLL patient experienced multiple enlarged tender diseased lymph nodes one week after first dosing that subsequently regressed, reminiscent of a tumor flare reaction that has been reported as a potential sign of anti-tumor activity in CLL patients treated with another immuno-oncology drug. The patient was assessed as stable disease at the pre-planned 12 week on-study assessment and also had a significant reduction in clonal B-cell count. Dosing in the LAVA-051 Phase 1/2a trial is ongoing, with subsequent cohorts planned to enroll patients in separate cohorts for intravenous and subcutaneous dosing. We expect to report additional clinical data from the trial when it is available, which may inform the design, including targeted populations, of a future pivotal trial.
Despite current treatment options, there remains an unmet need for patients with CLL, MM and AML, as the vast majority will become refractory to or develop resistance to existing therapies.
Chronic lymphocytic leukemia
CLL is the most common leukemia in the U.S. and Europe. CLL has an incidence of approximately 4.7 cases per 100,000 people in the U.S., and an increasing incidence in Western Europe including up to 5.27 per 100,000 in the UK. The disease has a male predominance and a median age at diagnosis of approximately 70 years.
CLL starts in white blood cells, called lymphocytes, in the bone marrow, and is caused by the monoclonal expansion of mature-appearing, functionally incompetent neoplastic B lymphocytes. As a disease, CLL has a highly variable presentation and as such, a variable clinical course. Most patients with CLL are initially asymptomatic and are managed with a watch-and-wait approach. In time, about two-thirds of patients will require treatment.
There is no standard front-line treatment regimen for all symptomatic CLL, mostly due to differences in patient age and frailty. In recent years, two new classes of drugs have been added to the primarily chemotherapy-based treatments: the BCL-2 inhibitor venetoclax and the Bruton’s tyrosine kinase (BTK) inhibitors, which are now broadly evaluated at various stages of disease and in different patient segments and combinations. When disease progression occurs, especially after treatment with DNA-damaging agents and the two drug classes mentioned earlier, CLL cells serially accumulate adverse biological features and increasingly develop resistance to existing therapies. Novel and more effective therapeutic approaches with an alternative mechanism of action and an acceptable safety profile are needed. Patients for whom no standard of care treatment currently exists are included in our clinical trial with LAVA-051.
Published studies have shown that CD1d levels are higher in more advanced stages of CLL, underscoring the potential of using CD1d as a target for Vg9Vd2 T cells in CLL immunotherapy.
MM is the second-most frequent blood cancer diagnosis in the U.S. and Western Europe, with an estimated incidence of about 4.5-6 per 100,000 people per year, with higher incidence in black male populations and lower incidence in Asian-Pacific populations. MM primarily affects elderly patients with a median age at diagnosis of 72 years.
MM is characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin known as M-protein. Plasma cells, a type of immune cell, are typically responsible for secreting antibodies to fight infection in a healthy person. In MM, the neoplastic plasma cells proliferate in the bone marrow and often result in extensive skeletal destruction with osteolytic lesions, osteopenia or pathologic fractures. Most patients with MM present with signs or symptoms related to the infiltration of plasma cells into the bone or other organs, or symptoms related to high levels of M-protein including reduced immune function.
Even though the treatment landscape for MM has evolved considerably, MM remains an incurable disease. Patients typically receive combination therapy consisting of two or more different classes of drugs, including immunomodulatory imide drugs, proteasome inhibitors, anti-CD38 antibodies and anti-BCMA B-cell maturation agent drugs. Combinations of different drugs are used upon failure of the previous treatment and disease progression. Upon relapse, the disease typically becomes more aggressive with shortened subsequent progression-free intervals. There is a critical need to develop novel therapeutic approaches with a different mechanism of action and an acceptable side-effect profile, particularly for relapsed refractory MM. LAVA-051 is being evaluated in MM patients who had progressive disease following treatment with existing drug classes used as standard therapy.
Several studies have demonstrated that patient MM cells express CD1d and that MM cells are susceptible to the cytolytic activity of both iNKT cells and gamma delta T cells. We believe that these data, combined with the demonstrated ability of LAVA-051 to trigger targeted anti-cancer activity of iNKT and gamma delta T cells in preclinical in vitro and in vivo MM models and against patient malignant cells ex vivo, supports the potential of targeting CD1d using LAVA-051 in MM.
Acute myeloid leukemia
AML is the most common form of acute leukemia in adults. The median age at diagnosis is 68 years and the age-adjusted incidence is about 4 per 100,000 people per year in the U.S. The incidence of AML increases, and its prognosis worsens, with age, ranging from a 5-year overall survival of 40-50% in patients under 50 years of age, to approximately 5-10% in older patients. Prognosis is also worse in patients with secondary AML.
AML is characterized by infiltration of the bone marrow, blood and other tissues by proliferative, clonal, abnormally differentiated, and occasionally poorly differentiated cells of the hematopoietic system.
The mainstay of AML treatment for patients under approximately 60 years of age and medically fit patients consists of intensive induction chemotherapy. For patients who are not eligible for intensive regimens, therapy includes best supportive care, low-dose cytarabine and hypomethylating agents decitabine and azacitidine alone or in combination with venetoclax. In the case of relapsed and/or refractory AML, patients are offered intensive salvage therapy with the aim of achieving a complete response and subsequent allogeneic hematopoietic stem cell transplant when deemed sufficiently physically fit. In other cases, patients receive low-intensity therapy or best supportive care.
In recent years, several novel treatments have been approved for certain treatment settings and/or subsets of AML patients, including approaches involving FLT3 inhibitors, IDH-2 inhibitors, IDH-1 inhibitors, and anti-CD33 antibodies. Despite the improved and more effective therapeutic options available to patients with AML, resistance has been shown to develop for most of these drug classes, underscoring the urgent need for efficacious therapies with novel mechanisms of action.
AML cells have been shown to be susceptible to lysis by iNKT cells as well as gamma delta T cells. Among AML patients, expression of CD1d was reported to be most pronounced in patients with the (myelo) monocytic subtypes, which was confirmed in the patient series that we studied. We believe these data, combined with the demonstrated activity of LAVA-051 in triggering relevant anti-cancer activity of iNKT and gamma delta T cells in preclinical in vitro and in vivo models and using ex vivo AML patient samples, support the potential of targeting CD1d using LAVA-051 in AML.
LAVA-1207 is a Gammabody that conditionally activates Vg9Vd2 T cells upon crosslinking to PSMA to trigger the potent and preferential killing of PSMA-positive tumor cells. LAVA-1207 specifically targets and mediates activation of Vg9Vd2 T cells against PSMA-expressing tumor cells. PSMA, a transmembrane protein, is expressed by most prostate tumors, and its expression is further increased in poorly differentiated, metastatic, and hormone-refractory carcinomas. Its expression profile in prostate cancer has been clinically validated and makes PSMA an important target for therapies for this form of cancer. In preclinical experiments, LAVA-1207 has been observed to be highly specific and potent in its ability to induce Vg9Vd2 T cell-mediated killing of PSMA-positive tumor cells.
In 2022, we dosed the first patient in a Phase 1/2a clinical trial evaluating LAVA-1207 in patients with mCRPC. The open-label, multi-center, Phase 1/2a clinical trial will evaluate safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and preliminary anti-tumor activity of LAVA-1207. The Phase 1 dose-escalation phase is designed to determine a recommended Phase 2a dose of LAVA-1207. Once a recommended Phase 2 dose has been established, the trial will expand into the Phase 2a portion to confirm safety and evaluate the preliminary anti-tumor activity of LAVA-1207 in patients with mCRPC. Enrollment for the Phase 1/2a clinical trial for LAVA-1207 is ongoing and we have activated eight clinical trial sites in Europe and the United States, most of which are actively recruiting.
In February 2023, at the American Society of Clinical Oncology Genitourinary Cancers Symposium (ASCO GU), we reported initial clinical data for the ongoing Phase 1/2a clinical trial of LAVA-1207. For the first five cohorts, these initial data demonstrated predictable and linear pharmacokinetics and on-mechanism pharmacodynamics and an favorable safety profile. Preliminary signs of anti-tumor activity were observed at week 8, with iRECIST stable disease (iSD) in 8 out of 14 evaluable patients and PSA levels stabilizing or decreasing in several patients. iRECIST is the response evaluation criteria in solid tumors, a set of published rules that define whether tumors in cancer patients have improved, stayed the same or worsened during treatment.
We expect to report additional safety and efficacy data for the dose escalation phase of the trial when it is available, which may inform the design of a future pivotal trial.
Prostate cancer is the second most common cancer among men in the U.S., with nearly 200,000 new diagnoses in 2020. It is estimated that 50,000 men with mCRPC are treated every year in the U.S. Several treatments are approved for mCRPC, including chemotherapies (docetaxel and cabazitaxel), next generation androgen receptor directed therapeutics (e.g., enzalutamide, abiraterone and (lutetium (177Lu)-vipivotide tetraxetan) and PARP inhibitors (for a small subset of patients with certain DNA damage repair mutations), which have collectively improved the therapeutic options for patients with mCRPC. The long-term outcome for patients with mCRPC is highly variable and will depend on prognostic factors of the underlying disease, its responsiveness to the available therapies and the co-morbidities of this generally elderly population. However, there is no curative treatment available today and additional new therapies are needed. Once mCRPC has metastasized beyond regional lymph nodes, the 5-year survival rate is 30%, and it is estimated that more than 33,000 men have died of mCRPC in the U.S. in 2020.
Prostate cancer is well-known for its immunosuppressive tumor microenvironment and generally low tumor mutational burden. These characteristics are believed to hamper the efficacy of classical CD3-based TCEs and other immuno-oncology compounds. According to published literature, prostate cancer is the solid tumor indication with the highest relative abundance of tumor-infiltrating Vg9Vd2 cells. This high relative abundance correlates with a lower biochemical recurrence (BCR) rate, which is related to an improved patient prognosis.
In September 2022, we entered into an exclusive worldwide license agreement with Seagen Inc. (Seagen) to develop, manufacture and commercialize SGN-EGFRd2 (LAVA-1223), an advanced preclinical asset that utilizes our proprietary Gammabody technology to target EGFR-expressing solid tumors. Under the terms of the agreement, we received a $50 million nonrefundable upfront payment in October 2022 and are eligible to receive up to approximately $650 million upon the achievement of development, regulatory and commercial milestones, as well as royalties ranging from the single digits to the mid-teens on future sales. The agreement also provides Seagen with the opportunity to exclusively negotiate rights to apply our proprietary Gammabody platform on up to two additional tumor targets.
LAVA-1266 is a Gammabody that conditionally activates Vg9Vd2 T cells upon crosslinking to CD123 (Iternleukin-3 receptor-alpha) to trigger the potent and preferential killing of CD123-positive tumor cells. CD123 is a clinically validated target and CD123 is expressed in a range of hematological malignancies, including AML, myelodysplastic syndrome (MDS), acute lymphocytic leukemia (ALL) and Hodgkin Lymphoma. There is a clear unmet need in these indications. We are investigating whether potential
challenges noted by various other CD-123 approaches (e.g., CRS, capillary leak syndrome, on-target off-tumor toxicity) could be overcome by the Gammabody platform approach. We are currently engaged in CTA/IND enabling activities and plan to seek a CTA or IND submission for LAVA-1266 in 2024.
We are also investigating LAVA-1278, a CD40 Gammabody, as a preclinical candidate for the treatment of several hematologic malignancies. We are currently engaged in preclinical activities and expect to engage in CTA/IND enabling activities so that we can seek CTA or IND submission for LAVA-1278 in 2025.
T cell engagers in cancer therapy
Current T cell engager approaches
Immuno-oncology aims to harness the power of the immune system to drive a durable anti-cancer response that starts with the recognition of malignant cells as “foreign” and the ability to overcome immune evasion mechanisms employed by cancer. Despite many successes in the field, one of the remaining fundamental challenges of leveraging the immune system for the treatment of cancer is to specifically activate immune effector cells against the tumor while avoiding immune activation against healthy cells. This requires, among other factors, specific effector T cell engagement and activation at the tumor site, often made ineffective in cancer patients due to tumor microenvironment (TME)-driven immune inhibition. Immunotherapy currently utilizes multiple approaches to T cell engagement including bispecific T cell engagement and CAR-T cell engagement.
The first approach makes use of bispecific antibodies that can engage all T cells, irrespective of their antigen recognition specificity. The second approach involves the adoptive transfer of engineered T cells, such as CAR-T cells, empowered with specific tumor recognition ability to generate anti-tumor activity de novo, independent of a pre-existing response.
In the bispecific antibody concept, the cytotoxic potential of effector T cells is redirected against the tumor. Through this approach, T cells are physically linked with tumor cells via bispecific antibodies that are composed of a T cell-binding domain and a tumor-binding domain. These TCEs primarily activate T cells through binding of CD3 in the T CR/CD3 receptor complex and can trigger broad activation of CD3-expressing T cells. These cells would otherwise individually require the specific recognition of a unique antigen in the context of polymorphic major histocompatibility complex (MHC) molecules for their activation. Thereby, TCEs can bypass the normal antigen restriction of classic T cells, causing activation independent of the epitope specificity of the T cell receptor.
The dual-targeting concept enabled by TCEs holds great therapeutic promise, but translation of the concept into treatments has proved challenging. The archetypical application, T cell redirection and engagement via CD3, was first described in the mid-1980s but did not reach patients until 2009 with the European Union approval of catumaxomab. Catumaxomab was delivered intraperitoneally, as systemic intravenous administration induced fatal toxicity at low doses due to Fc-mediated off-target T cell activation in the liver. Catumaxomab was withdrawn from the market in 2017 for commercial reasons, but the impressive clinical results of another approved CD3-based TCE, blinatumomab (CD3 × B lymphocyte antigen CD19), sparked renewed interest and investment in this approach. This is reflected by the numerous TCEs currently in clinical development for hematologic and solid tumor indications.
The second approach is the CAR-T cell, or engineered cell therapy, strategy in which patient T cells are harvested and genetically engineered to carry a chimeric receptor allowing recognition of a specific target antigen on the tumor cell. Adoptive transfer of these cells results in activation of the CAR-T cells and tumor cell killing. To date, multiple CAR-T therapies have generated promising clinical data, and multiple CAR-T cell therapies targeting CD19, including KYMRIAH® (tisagenlecleucel), YESCARTA® (axicabtagene ciloleucel), TECARTUS® (brexucabtagene autoleucel) and BREYANZI® (lisocabtagene maraleucel), and a BCMA-targeted CAR-T cell therapy ABECMA® (idecabtagene vicleucel), have been approved. Many more CAR-T therapies are being developed against different targets and leveraging effector activity of different cell types. The currently approved therapies are personalized approaches based on relatively complex and clinically aggressive technologies and procedures, in which a patient’s own T cells are initially extracted and then re-administered after being modified and after the patient has undergone bone marrow conditioning with high-
dose chemotherapy. A next-generation approach is also in early-stage development, based on the same complex engineering and manufacturing process but aimed at having off-the-shelf allogeneic cell product that can be used for several patients without lag time.
Challenges with current TCE approaches
Current TCE approaches, including CD3 TCEs and CAR-T approaches, have demonstrated anti-cancer activity in clinical settings, but have also been limited in their use due to several key challenges, including:
|●||Limited therapeutic window: Side effects and dose-limiting toxicities, most prominently related to CRS and on-target/off-tumor related toxicities, have been observed in both early-stage TCE and CAR-T approaches.|
|●||High variability in effectiveness: CD3 TCEs dampen the antitumor efficacy of cytotoxic T cells through activation of immune-suppressive Tregs which has resulted in variability of clinical efficacy.|
|●||Patient preconditioning: For CAR-T, high doses of chemotherapy are typically needed to precondition the patient by lymphodepletion. Such lymphodepletion creates space for CAR-T cells and improves their homeostatic expansion and therapeutic efficacy, but it also results in side effects associated with both high- dose chemotherapy and leukopenia.|
|●||Manufacturing and logistics complexity: CAR-T manufacturing complexities to date means that products cannot always be successfully produced for patients. Lengthy processes result in lag times for treatment administration, resulting in a long vein-to-vein time and a limited addressable patient population.|
We are a clinical stage immuno-oncology company focused on developing our proprietary Gammabody™ platform of bispecific gamma-delta T cell engagers to transform the treatment of cancer. Using our Gammabody platform, we are developing a portfolio of novel bispecific antibodies designed to engage and leverage the potency and precision of gamma delta T cells to orchestrate a robust, natural anti-tumor immune response and improve outcomes for cancer patients. We are focused on discovering, developing and ultimately commercializing proprietary, off-the-shelf, targeted Gammabody drug candidates that leverage the power of gamma delta T cells with the validated benefits of antibody-based treatments. Key components to our strategy include:
|●||Establish ourselves as the leader in the development of gamma delta T cell engagers for the treatment of cancer.|
|●||Rapidly accelerate the clinical development of our lead candidates, LAVA-051 and LAVA-1207, to support proof-of-concept and other enabling activities for our investigational candidates.|
|●||Achieve competitive excellence by leveraging the transformational potential of our platform to advance and expand our earlier stage pipeline while broadening the applications of the platform to additional targets and patient populations.|
|●||Enhance our pipeline and platform through strategic partnership and collaboration opportunities.|
|●||Leverage and continue to build our intellectual property portfolio in order to protect our Gammabody platform and our leadership position in gamma delta bsTCEs.|
Gammabody (gamma delta bsTCEs): a potential new class of immuno-oncology treatments
The successes of current TCE approaches highlight the high potential of re-directing effector T cell responses as a therapeutic strategy to improve cancer patients’ outcomes. In particular, the large number of trials with bispecific TCEs in cancer is further testimony to how this approach is, potentially the most promising from both a clinical and commercial perspective. We have identified the engagement of gamma delta T cells as the next-generation application of TCEs and believe our Gammabody platform may address limitations of current TCEs to improve patient outcomes in both hematologic malignancies and solid tumors.
Vgamma9 Vdelta2 (Vg9Vd2) T cells in cancer therapy
Background on Vg9Vd2 T cells
T lymphocytes are divided into two main categories based on T cell receptor type: aß, or alpha beta, and gd, or gamma delta, T cells. Gamma delta T cells represent approximately 1-5% of all T cells in circulation. Human gamma delta T cells are further classified based on the combination of their Vgamma (Vg) and Vdelta (Vd) receptor chains, with Vg9Vd2 T cells representing about 90% of all gamma delta T cells in circulation. In addition, these Vg9Vd2 T cells have been observed to infiltrate tumors in which greater relative abundance correlates with favorable outcome.
Although most human T cells express an alpha beta TCR, a smaller proportion of T cells express a gamma delta TCR. Conventional alpha beta TCR bearing T cells can be subdivided in two major subtypes: CD4 expressing “helper” T cells, and CD8 expressing “cytotoxic” T cells. Both alpha beta T cell populations recognize specific peptides loaded onto MHC molecules—MHC class II in the case of CD4-positive T cells, and MHC class I in the case of CD8-positive T cells. In contrast, gamma delta T cells typically recognize their ligands independent of classical antigen processing and MHC restriction. The gamma delta T cell population can be roughly divided into two large sub-populations: Vdelta1 (Vd1) and Vdelta2 (Vd2) TCR expressing gamma delta T cells. The Vdelta2 population of gamma delta T cells associate almost invariably with the Vgamma9-chain, resulting in a very homogeneous effector cell population. This population has a monomorphic TCR with a well-defined specificity for butyrophilin molecules (BTN3A1/2A1)-in complex with phosphoantigen, a well-defined proinflammatory functional profile and a unique capacity to also act as antigen-presenting cells upon their activation.
In contrast, Vdelta1 T cells constitute a heterogeneous population of cells in part because the Vdelta1 chain can pair with several Vgamma chains, such as Vgamma4,5,9, and also with alpha beta-TCR, and has more variability in TCR CDRs. Consequently, Vdelta1 T cell subsets recognize various antigen presenting molecules and can recognize various antigens. Vdelta1 T cells also have substantial functional diversity not only being able to exert cytotoxic effects, but also play a role in tissue homeostasis, repair and immune suppression. Both cell subsets can infiltrate tumors, but protumor functions related to IL-17 production and a regulatory phenotype have only been reported for tumor-infiltrating Vdelta1 T cells, and in various tumor types infiltration of Vdelta1 has in a number of studies been demonstrated to be related to poorer patient outcome, while Vdelta2 tumor infiltration has generally been shown to correlate to positive prognosis.
When these Vg9Vd2 T cells are activated, they secrete pro-inflammatory cytokines that trigger downstream immune cells from the innate and adaptive immune system, including alpha beta T cells, NK cells and dendritic cells. Activated Vg9Vd2 T cells have a distinct ability to take up, process and present antigens to alpha beta T cells, which may prime the adaptive immune system for a memory response, potentially resulting in deep and durable responses against disease.
Targeting Vg9Vd2 T cells for cancer treatments
As mentioned above, Vg9Vd2 T cells have been observed to infiltrate tumors in a wide variety of cancer indications and can provide effective anti-tumor immune responses against both hematologic malignancies and solid tumors. These T cells contain a tumor recognition mechanism, allowing them to recognize and kill cancerous cells, while leaving healthy cells unharmed. Vg9Vd2 T cells represent a potent and relatively homogeneous class of proinflammatory immune effector cells with an immune surveillance function.
Because Vg9Vd2 T cells have properties of both the innate and adaptive immune systems, they serve as a functional bridge between these two critical systems to effect tumor killing. They have the capability to be activated for immediate and potent killing of tumor cells, as well as the potential to induce a cascade response in which they trigger innate and adaptive immune cells through cytokine release and antigen presentation. The latter may induce immunological memory and result in not only potent, but also durable responses.
Vg9Vd2 T cells detect and kill tumor cells by indirectly detecting specific metabolites, called phosphoantigens, which often accumulate intracellularly at relatively high levels in tumor cells. These phosphoantigens bind to an intracellular domain of the cell-surface receptor, butyrophilin, triggering a conformational change and the recognition of butyrophilin receptors on tumor cells by Vg9Vd2 T cells. Upon this interaction with tumor cells, Vg9Vd2 T cells are activated and release cytolytic molecules that can directly kill cancer cells and simultaneously produce pro-inflammatory cytokines that can attract other immune cells and trigger anti-cancer activity.
As reported in a landmark publication in Nature Medicine in 2015, the presence of tumor-infiltrating gamma delta T cells has shown the highest correlation with favorable outcomes for cancer patients as compared with other leukocyte subpopulations present in tumors. Further, as reported in Oncoimmunology in 2017, infiltration of Vg9Vd2 T cells was confirmed in a large set of different tumors, including cancers with a low incidence of alpha beta T cell infiltration (also called: cold tumors).
The unique anti-cancer potential of gamma delta T cells drove prior attempts to evaluate them in clinical trials. Various clinical trials were conducted utilizing either adoptive cell therapy of ex vivo expanded activated autologous or allogeneic gamma delta T cells or in vivo gamma delta T cell activation approaches with synthetic phosphoantigens or aminobisphosphonates. However, the results from these prior trials were not consistent or robust enough to support further development. Lack of tumor-targeted activation and observed exhaustion of gamma delta T cells may have dampened clinical responses. Based on our preclinical data, we believe that an important root cause for underwhelming efficacy of these approaches is the systemic non-tumor specific activation of Vg9Vd2 T cells. We believe a targeted approach utilizing a gamma delta bsTCE could materially improve clinical responses while maintaining a good safety profile.
Advantages of our Gammabody approach
Gamma delta bsTCEs represent an emerging new class of targeted immuno-oncology treatments. By engaging only Vg9Vd2 T cells, instead of all CD3-expressing T cells, our approach is designed to enable therapeutic options that overcome the limitations of previous and existing TCE approaches in the treatment of cancer. We believe our approach has the following advantages:
|●||High potency. We have demonstrated high antitumor potency in vitro and ex vivo using both cell lines and patient tumor samples with our Gammabody platform, with an average EC50 in the low picomolar range. This suggests that clinical antitumor activity may be triggered using relatively low doses.|
|●||Low anticipated risk of high grade CRS. Our early-stage Phase 1 clinical trials for LAVA-051 and LAVA-1207 have had no occurrence of high grade (>grade 2) CRS to date. Similarly, our (surrogate) Gammabody molecules did not result in any high grade CRS in non-human primate studies. This is consistent with earlier clinical studies of gamma delta T cell-based therapeutic approaches, including those that triggered systemic activation of the entire Vg9Vd2 T cell population.|
|●||Potential activity in hematologic malignancies and solid tumors, including immunologically “cold” tumors.|
|Our Gammabody molecules can trigger activation of both peripheral blood and tumor-infiltrating Vg9Vd2 T cells, allowing access to and activity against both hematologic malignancies and solid tumors, potentially including those that have not been successfully addressed using immune checkpoint inhibitors.|
|●||Broad therapeutic window. Vg9Vd2 T cells have an inherent ability to distinguish cancerous from normal cells, which is retained in our Gammabody technology. Based on our preclinical data, we expect the optimal dose to be well below the toxic dose. We believe that the high tumor selectivity and potency of our Gammabody molecules, in combination with the low risk of CRS, may provide a broad therapeutic window.|
|●||Fully modular, allowing for the use of existing tumor-targeting antibodies. Our platform is fully modular, enabling existing antibodies or antibody fragments to be incorporated into our Gammabody platform. This allows us to expedite the discovery and development of clinical candidates since no de-novo antibody panel generation is required. In addition, our platform uses standardized development procedures that are well-known to regulatory authorities.|
|●||Well-established, standardized manufacturing process. Our Gammabody molecules are off-the-shelf products, which are manufactured using well-established, standardized processes that avoid the higher costs, complexities, product variability and treatment delays associated with the manufacturing of cellular products, such as CAR-T therapies.|
|●||Potential combination with immune checkpoint inhibitors and other oncology approaches. Because of their distinct mechanism of action and targeted nature, our Gammabody molecules have the potential to be combined with a variety of current standard-of-care therapies, including cytotoxic agents, anti-PD-1/PD-L1 agents, monoclonal antibodies and other cell therapy approaches, for the treatment of a wide range of cancer indications.|
Our novel constructs
Our Gammabody molecules utilize humanized and highly specific single domain antibodies, which are known as VHH antibody fragments. VHH antibodies are known to have several key pharmaceutical advantages over conventional antibodies.
VHH antibodies have been shown to be able to access unique epitopes that may not be accessible for conventional antibodies. VHH single domain antibodies are readily humanized and are known for their high stability, solubility and ease of manufacturing. The use of VHH single domain antibody components and their therapeutic potential has been validated by the approval of caplacizumab for patients with acquired thrombotic thrombocytopenic purpura.
As depicted below, we are developing a novel proprietary platform in two relatively small Gammabody formats: a bispecific format in which a Vdelta2 T cell receptor-specific VHH is linked to a tumor-targeting VHH via a short and clinically validated linker, and a bispecific format with a silenced Fragment crystallizable (fc) domain (VHH-Fc). We believe that the combination of a relatively small size and the Fc-mediated half-life extension facilitates tumor penetration and is therefore advantageous for the development of compounds targeting solid tumors.
Our manufacturing advantages
We have demonstrated that bispecific VHH antibodies can be produced in yeast, which allows for robust and low-cost production. Fc-domain-containing bispecific VHH-domain antibodies are produced using the widely used Chinese Hamster Ovary (CHO) manufacturing platform and knobs-into-holes (KiH) technology. KiH technology has been widely validated and is based on the introduction of a single amino acid “knob” mutation on the one heavy chain Fc, which fits into a complementary “hole” created by a three-amino acid mutation on the other heavy chain Fc. Bispecific VHH-Fc are thus produced in a single CHO cell line in which favored heterodimer pairing ensures high yields of the bispecific product.
Our Gammabody platform
We have developed a proprietary Gammabody platform that optimizes tumor-targeted activation of Vg9Vd2 cells for tumor cell killing, retains and leverages the inherent tumor cell recognition and killing capabilities of these cells and drives a downstream immune response cascade against tumor cells. Our platform combines the power and natural selectivity of Vg9Vd2 T cells and their ability to activate both arms of the immune system with the targeting advantages of small-sized bispecifics, providing the opportunity to significantly improve upon classical T cell engager approaches, as well as upon earlier strategies for recruiting gamma delta T cells for cancer therapy.
In the graphic below, the left panel shows the natural activation mechanism of Vg9Vd2 T cells, which, through recognition of phosphoantigen-activated butyrophilins, leads to tumor cell killing. The right panel depicts our approach using our Gammabody platform. This Gammabody molecule binds Vg9Vd2 T cells and a tumor-associated antigen of choice. Crosslinking via our Gammabody leads to activation of Vg9Vd2 T cells and potent tumor cell killing. While our approach bypasses the requirement of interactions between the Vg9Vd2 TCR and phosphoantigen-activated butyrophilins, Gammabody molecule bound Vg9Vd2 T cells retain the inherent tumor specificity of Vg9Vd2 T cells. We have shown in our preclinical work that this results in strong activity against tumor cells, but only limited activity against healthy cells expressing the same target.
LAVA’s proprietary Gammabody platform engages Vg9Vd2 T cells for targeted cancer treatment.
Our approach targets antigens that are frequently expressed at higher levels on tumor cells as compared to healthy cells. In addition, our platform avoids the detrimental co-activation of immune-suppressive cells, such as Tregs, that is typically observed with CD3 or pan-T cell TCEs, which can dampen the development of effective antitumor responses. We have conducted preclinical experiments that have shown that Treg activation, as assessed by flowcytometric detection of the early activation-marker CD69, is induced by a CD3-based TCE, but not by our Gammabody. Since our platform does not activate immune suppressive cells like Tregs, we believe this dampening effect is unlikely to occur with our Gammabody molecules, increasing their potential efficacy compared to CD3-based TCEs.
We believe our Gammabody molecules drive a cascade response that potentially provides for enhanced anti-tumor efficacy. After the initial activation of Vg9Vd2 T cells is mediated through our Gammabody molecules, the activated Vg9Vd2 T cells are designed to rapidly kill tumor target cells and have the potential for:
|●||Expansion. The Vg9Vd2 T cells proliferate, resulting in an increased number of anti-tumor Vg9Vd2 T cells.|
|●||Broad immune activation. The Vg9Vd2 T cells trigger the activation and antitumor activity of other immune cells, such as NK cells, alpha-beta T cells and dendritic cells.|
|●||Antigen presentation. The Vg9Vd2 T cells process and present tumor antigens and acquire dendritic cell- like antigen presenting functions to trigger the development of “classical” naïve CD4+ and CD8+ alpha-beta T cell responses against the tumor.|
We believe that this cascade of events may enhance potency and lead to a more durable immune response.
Preclinical support for our mechanism of action and safety
We believe that our Gammabody platform possesses features that have the potential to address several shortcomings of current TCE approaches for cancer. We have conducted multiple preclinical experiments where our Gammabody molecules have shown potent, selective, sustained and serial killing of tumor cells. Anti-tumor activity has been shown in in vivo preclinical animal models and in ex vivo models using patient tumor and Vg9Vd2 T cells. Our preclinical experiments have also shown that activation of the Vg9Vd2 T cell population is conditional upon Gammabody crosslinking.
In our studies in non-human primates (NHPs), surrogate Gammabody molecules were shown to be safe and well-tolerated. NHP studies were performed in cynomolgus monkeys with fully cross-reactive surrogate Gammabody molecules. The gamma delta bsTCEs used were designed to trigger human and monkey gamma delta T cells with similar potency. Administration of the cross-reactive surrogate Gammabody led to high sustained plasma levels and dose-dependent accumulation in relevant tissues with no safety-related effects and no signs of high grade CRS.

In May 2020, we entered into the Janssen Agreement for the discovery and development of novel bispecific antibody-based gamma delta T cell engagers for the treatment of cancer. Under the Janssen Agreement, we granted Janssen an exclusive, sublicensable, worldwide license under certain of our patents, materials, and know-how, including certain rights assigned to us pursuant to the VUmc Agreement, to exploit multi-specific antibody products which have variable domains specific to the licensed target or products which are directed to the licensed target, in all fields of use. We retain the right to use our technology to perform our obligations under the Janssen Agreement and for all purposes not granted to Janssen.
Together with Janssen, we are conducting certain research and discovery activities pursuant to a mutually agreed research plan designed to develop licensed product candidates not later than the stage of candidate selection. The parties have established a joint steering committee to oversee the research, information sharing, and potential amendments of the research plan. We are responsible for conducting research activities at our expense and are entitled to certain milestone payments from Janssen for product candidates that progress through certain research stages, as may be amended by the joint steering committee. Following completion of such research, Janssen has the right to determine whether to bring one or more designated
product candidates forward into further development. If Janssen so elects, Janssen is responsible for the development, manufacture, and commercialization of the licensed products at Janssen’s sole cost and expense. Janssen is required to use commercially reasonable efforts to exploit one licensed product.
In May 2020, we received an upfront fee of $8.0 million and achieved research milestones necessary to receive $2.0 million, $1.0 million of which was received in October 2021, and $1.0 million of which was received in December 2020. We are also eligible to receive up to an aggregate of $195 million upon the achievement of certain development and commercial milestones. We also are entitled to receive tiered royalties based on commercial sales levels from low to mid-single digit percentages of net sales of licensed products for a fixed period beginning with the first commercial sale of such a licensed product in a given country of sale and expiring ten years after such sale.
Until the earlier of termination of the Janssen Agreement and a specified period of time following the first commercial sale of a licensed product, we cannot directly or through a third-party research, develop or commercialize or exploit a competing biological product that is directed to or otherwise targets the licensed target, subject to certain exceptions and limitations for third party acquiror products.
As a general rule, ownership of any inventions made by either party in the course of performing their respective activities pursuant to the Janssen Agreement will follow inventorship of such inventions, with certain defined exclusions. First, Janssen will own any invention made by either party in the course of performing their respective activities pursuant to the Janssen Agreement that is an improvement to Janssen’s background technology, relates to an antibody directed to the licensed target, is a medical use or method of treatment or relates to a licensed product. Second, we will own any invention made by either party in the course of performing their respective activities pursuant to the Janssen Agreement that is an improvement to our background technology but that is not a licensed product or that is obtained from use of the specific antibody but not as part of a licensed product. We received from Janssen a non-exclusive, worldwide, non-royalty bearing, sublicensable license under certain know-how developed by Janssen under the Janssen Agreement, and patents claiming such know-how, for certain uses necessary to exploit the specific antibodies.
The Janssen Agreement expires on a licensed product-by-licensed product basis upon the expiration of Janssen’s payment obligations. Janssen may terminate the Janssen Agreement in its entirety or on a country-by-country basis for convenience following a certain notice period, or in its entirety within a defined timeframe following our change of control. Either party may terminate the Janssen Agreement upon an uncured material breach of the agreement or insolvency of the other party following a certain notice period. Following each research stage, the Janssen Agreement will automatically terminate if the parties decide not to proceed with the subsequent research stage or, following the completion of all research stages, if Janssen decides not to bring a candidate forward into further development. Depending on the reason and stage of termination, we have certain rights to receive a license to certain intellectual property generated by Janssen under the Janssen Agreement for purposes of continued development and commercialization of research results and/or product candidates developed under the Janssen Agreement.
In 2017, we entered into the VUmc Agreement. Under the VUmc Agreement, VUmc granted us an exclusive, although non-exclusive with respect to certain intangible know-how, worldwide, sublicensable license under certain patent rights and know-how owned by VUmc, effectively including research and other services provided in collaboration by VUmc since 2017 to develop, make, and sell licensed products. In 2021, VUmc assigned all of the patent rights previously licensed by us under the VUmc Agreement for no additional consideration paid. VUmc retains the right to use the patent rights and know-how for solely non-commercial research and educational purposes, but it may not conduct such work with respect to any product that is directed to a specified target for a specified time period.
Following the assignment of such patent rights, we remain obligated to pay VUmc sub to low single-digit tiered royalties on net sales of products covered by claims included in the assigned patent rights. Royalties are payable on a country-by-country basis for a royalty term that expires upon the expiration of the last valid claim in the assigned patent rights in such country that would be infringed by the use, manufacture, or sale of a product in such country in the absence of us having rights to such patent right. In connection with our IPO,
we issued to VUmc 235,664 of our common share and paid $0.3 million in cash. On each of the first and second anniversary of our IPO, we are required to pay $4.7 million. Such payment shall be made in cash or common shares, at the election of the Company, valued using the closing price of common shares on the date two trading days prior to the respective anniversary of our IPO. In 2022, the Company issued 491,352 common shares to VUmc representing 50% of the payable in accordance with the VUmc agreement for the first anniversary payment. The final payment is due at the second anniversary of our IPO in March 2023. The Company and VUmc continue to collaborate and VUmc makes available certain employees to the Company who perform research and other activities for the benefit of the Company.
The continuing obligations under the VUmc Agreement, including our obligation to pay royalties, expires on a country-by-country basis upon the expiration of the last to expire valid claim of the assigned patents in such country. Following the expiration of our royalty obligations as to an assigned product in a country, we will retain title to the assigned patent rights and will no longer be obligated to pay royalties for such products. We control the prosecution and maintenance of the patent rights. Unless sooner terminated, the term of the license continues until the expiration of the last to expire of the patent rights, the latest of which is currently expected to expire in 2036.
In 2021, we entered into a master research services agreement with VUmc under which VUmc performs certain clinical research services and preclinical development for us under the direction of our Chief Scientific Officer. Under this master research services agreement, we own all rights, title, ownership and interest in and to any inventions made, created or prepared by VUmc in connection with the Agreement. This agreement automatically terminates in the case of our bankruptcy. Either party may terminate this agreement upon 60 days’ written notice for any reason or upon 60 days’ written notice upon uncured material breaches of the terms of the agreement.
Manufacturing, sales and marketing
Given the stage of our lead programs, we are in the process of building our U.S. commercial, medical affairs and manufacturing infrastructure and intend to build, alone or with potential future partners, our global commercialization and distribution capabilities over time for our lead clinical candidates. We do not own or operate manufacturing facilities for the production of our clinical candidates, and we rely on third-party contract manufacturers for all of our required raw materials, manufacturing devices, active pharmaceutical ingredients and finished product for our preclinical research and clinical trials. The prices of our primary raw materials have not historically been volatile.
The biotechnology industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on intellectual property and proprietary rights. We believe that our proprietary Gammabody platform and our product candidates, strategic collaboration and scientific and clinical expertise may provide us with competitive advantages. Any product candidates that we successfully develop and commercialize will have to compete with existing therapies and new therapies that may become available in the future. We also face potential competition from a variety of companies in the gamma delta T cell field.
Our competitors in the field of gamma delta T cell therapy include Adicet Bio, Inc., Editas Medicine, Inc., Takeda Pharmaceutical Company Ltd, ImCheck Therapeutics SAS, Immatics Biotechnologies GmbH, Leucid Bio Ltd, PhosphoGam Inc., Shattuck Labs Inc., Sandhill Therapeutics, Inc, Gadeta BV, Eureka Therapeutics, Inc., In8Bio, Inc., and TC BioPharm Limited. Our gamma delta T cell product candidates may also compete with other T cell engaging therapies as well as NK cell-engaging therapies.
In addition, many of our current or potential competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials and delivering approved products than we do today. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. We also compete with these companies in recruiting, hiring and retaining qualified scientific and management talent, establishing clinical trial sites and patient registration for clinical trials, obtaining
manufacturing slots at contract manufacturing organizations, and in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective (particularly if they represent cures), have fewer or less severe side effects, are more convenient, or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. The key competitive factors affecting the success of all of our programs are likely to be their efficacy, safety, method of administration and availability of reimbursement.
We actively seek to protect our proprietary technology, inventions, improvements to inventions and other intellectual property that is commercially important to the development of our business by a variety of means, such as seeking, maintaining and defending patent rights, whether developed internally or licensed from third parties. We also may rely on trade secrets and know-how relating to our proprietary technology platform, on continuing technological innovation and on future in-licensing opportunities to develop, strengthen and maintain the strength of our position in the field of biotechnology that may be important for the development of our business. Additional regulatory protection may also be afforded through data exclusivity, market exclusivity and patent term extensions where available.
We have developed or exclusively in-licensed numerous patent and patent applications, know-how and trade secrets relating to the development and commercialization of our product candidates and the underlying Gammabody platform. We currently own or in-license: three issued U.S. patents, seven pending U.S. patent applications, seven pending European regional-phase patent applications, three pending PCT patent application, fourteen issued patents in other territories and fifty two pending patent applications in other territories that are important to the development of our business.
Our strategic initiative is to protect proprietary technology, inventions and improvements to inventions and other intellectual property that may be commercially important to the development of our business. We also intend to seek additional patent protection or rely upon trade secret rights to protect other technologies that may be used to manufacture and develop our gamma delta T cell products. We are a party to license and assignment agreements that grant us exclusive rights to use specific technologies in our gamma-delta T cell products and in the manufacturing and development of our products. For more information, see “Intellectual Property.”
Our future commercial success depends, in part, on our ability to: obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business; defend and enforce our patents; preserve the confidentiality of our trade secrets; and operate without infringing the valid enforceable patents and proprietary rights of third parties. Our ability to stop third parties from making, using, selling, offering to sell or importing our products may depend on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities. With respect to both our owned and licensed intellectual property, we cannot be sure that patents will issue with respect to any of the pending patent applications to which we license rights or with respect to any patent applications that we or our licensors may file in the future, nor can we be sure that any of our licensed patents or any patents that may be issued in the future to us or our licensors will be commercially useful in protecting our product candidates and methods of manufacturing the same.
Our patent portfolio
As of December 31, 2022, our patent portfolio included U.S. and foreign patents and patent applications. Our patent portfolio also includes in-licensed patents and patent applications that we have filed on our own technologies, including technologies related to our preclinical programs and our manufacturing technologies. The patents and patent applications in our patent portfolio cover technology used in our own development programs, as well as technology used in our collaborations with Seagen and Janssen. We have granted Seagen an exclusive worldwide license for the development and commercialization of SGN-EGFRd2 (LAVA-1223), an advanced preclinical asset that utilizes LAVA’s proprietary Gammabody technology to target
epidermal growth factor receptor (EGFR)-expressing solid tumors. We have granted Janssen an exclusive worldwide license for the development and commercialization of a confidential product candidate.
The issued patents and patent applications directed to our most advanced programs are summarized below:
For LAVA-051, LAVA’s patent portfolio includes two issued U.S. patents and five U.S. pending patent applications, five pending European patent applications, fourteen foreign issued patents and twenty seven pending foreign patent applications. These patent and patent applications contain claims or supporting disclosures directed to the LAVA-051 composition of matter and to methods of treating diseases of interest using LAVA-051. These issued patents and patents issuing from these pending patent applications, if any, are expected to expire between 2035 and 2039, excluding any potential patent term extensions or patent term adjustments.
For LAVA-1207, LAVA’s patent portfolio includes one issued U.S. patent, two U.S pending patent applications, two pending European patent applications, eight foreign issued patents, eight foreign pending patent applications and two pending PCT patent applications containing claims or supporting disclosures directed to the LAVA-1207 composition of matter and to methods of treating diseases of interest using LAVA-1207. This issued patent and patents issuing from these pending patent applications, if any, are expected to expire between 2035 and 2041, excluding any potential patent term extensions or patent term adjustments.
For LAVA-1266, LAVA’s patent portfolio includes one issued U.S. patent, two U.S pending patent applications, two pending European patent applications, eight foreign issued patents, eight foreign pending patent applications and three pending PCT patent applications containing claims or supporting disclosures directed to the LAVA-1266 lead composition of matter and to methods of treating diseases of interest using LAVA-1266 is issued patent and patents issuing from these pending patent applications, if any, are expected to expire between 2035 and 2042, excluding any potential patent term extensions or patent term adjustments.
For LAVA-1278, LAVA’s patent portfolio includes one issued U.S. patent, three U.S pending patent applications, three pending European patent applications, eight foreign issued patents, eighteen foreign pending patent applications and two pending PCT patent applications containing claims or supporting disclosures directed to the LAVA-1278 lead composition of matter and to methods of treating diseases of interest using the LAVA-1278 lead compound. This issued patent and patents issuing from these pending patent applications, if any, are expected to expire between 2035 and 2040, excluding any potential patent term extensions or patent term adjustments.
We believe our manufacturing and assay development patents, patent applications and related know-how may provide us with additional intellectual property protection relating to LAVA-051, LAVA-1207 and preclinical candidates.
Our patent portfolio also includes patent families relating to our Gammabody platform, including three patent families that are generally related to the antibodies that activate gamma delta T cells, dosing of such antibodies and uses of such antibodies for certain patient groups.
Patent term and term extensions
The term of a patent, and the protection it affords, is limited. Individual patents have terms for varying periods depending on the date of filing of the patent application or the date of patent issuance and the legal term of patents in the countries in which they are obtained. Generally, utility patents issued for applications filed in the United States are granted a term of 20 years from the earliest effective filing date of a non-provisional patent application. However, as to the extension associated with FDA approval, the extension cannot be longer than
five years and cannot extend the patent term beyond 14 years from the date of FDA approval. In addition, only one patent applicable to an FDA-approved drug or biologic is eligible for the extension, and only those claims covering the approved drug, a method for using it, or a method of manufacturing may be extended. The terms of foreign patents vary in accordance with provisions of applicable local law, but typically are also 20 years from the earliest effective filing date and similar provisions are available in certain foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if our product candidates receive FDA approval, we expect to apply for patent term extensions where applicable on patents covering those products.
We plan to seek patent term extensions to any of our issued patents in any jurisdiction where these are available. However, there is no guarantee that the applicable authorities, including the FDA in the United States, will agree with our assessment of whether these extensions should be granted, and if granted, the length of these extensions. All taxes, annuities or maintenance fees for a patent, as required by the USPTO and various foreign jurisdictions, must be timely paid in order for the patent to remain in force for the full term.
Our patents and patent applications may be subject to procedural or legal challenges by others. We may be unable to obtain, maintain and protect the intellectual property rights necessary to conduct our business, and we may be subject to claims that we infringe, misappropriate or otherwise violate the intellectual property rights of others, which could materially harm our business. For more information, see the section titled “Risk Factors—Risks Related to Our Intellectual Property.”
Trade secrets and know-how
We also rely on trade secrets, know-how, continuing technological innovation and confidentiality agreements to develop and maintain our proprietary position and protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection, including our proprietary processes for expanding and activating therapeutic quantities of gamma delta T cells and modified gamma-delta T cells. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and others who may have access to proprietary information, under which they are bound to keep all confidential information concerning our business or financial affairs developed by or made known to them during the course of the party’s relationship with us confidential and not disclose such information to third parties except in specific circumstances, and in certain cases, to assign to us inventions made during the term of their employment or service. However, trade secrets can be difficult to protect. We cannot guarantee that we have entered into confidentiality agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes or that these agreements will afford us adequate protection of our intellectual property and proprietary rights. These agreements and policies may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets or substantially equivalent proprietary information and techniques may otherwise become known or be independently discovered by competitors. To the extent that our contractors, commercial partners, collaborators, employees or consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in the resulting know-how and inventions. For more information, see the section titled “Risk Factors—Risks Related to Our Intellectual Property.”
We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems.
The FDA and other regulatory authorities at federal, state, and local levels, and in the European Union and in other foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring, and post- approval reporting of biologics such as those we are developing. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates.
The process required by the FDA before biologic product candidates may be marketed in the United States generally involves the following:
|●||completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s current Good Laboratory Practices regulation;|
|●||submission to the FDA of an IND, which must become effective before clinical trials may begin and must be updated annually or when significant changes are made;|
|●||approval by an independent IRB or ethics committee at each treatment site before the trial is commenced;|
|●||performance of adequate and well controlled human clinical trials to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose;|
|●||preparation of and submission to the FDA of a BLA after completion of all pivotal clinical trials;|
|●||satisfactory completion of an FDA Advisory Committee review, if applicable;|
|●||a determination by the FDA within 60 days of its receipt of a BLA to file the application for review;|
|●||satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP and to assure that the facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency, and of selected clinical investigation sites to assess compliance with Good Clinical Practices, or GCP; and|
|●||FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States.|
Preclinical and clinical development
Before testing any biologic product candidate in humans, the product candidate must undergo preclinical testing. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as in vivo studies to assess the potential safety and activity of the product candidate.
Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA and a CTA to the EMA for trials conducted in the United States and European Union, respectively. An IND and CTA are requests for authorization to administer an investigational new drug product to humans. The central focus of an IND or a CTA submission is on the general investigational plan and the protocol(s) for clinical studies. The IND or a CTA also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product; chemistry, manufacturing, and controls information; and any available human data or literature to support the use of the investigational product. An IND or a CTA must be cleared or approved before human clinical trials may begin.
Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments.
Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site and must monitor the study until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety
monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.
For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap.
|●||Phase 1—The investigational product is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness.|
|●||Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.|
|●||Phase 3—The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval.|
During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to regulatory agencies.
Post-approval clinical trials, sometimes referred to as Phase 4 studies may be made a condition to approval of the BLA.
Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final product, or for biologics, the safety, purity and potency. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.
Compliance with cGMP requirements
Manufacturers of biologics must comply with applicable cGMP regulations, including quality control and quality assurance and maintenance of records and documentation. Manufacturers and others involved in the manufacture and distribution of such products also must register their establishments with FDA and certain state agencies. Both domestic and foreign manufacturing establishments must register and provide additional information to FDA upon their initial participation in the manufacturing process. Establishments may be subject to periodic, unannounced inspections by government authorities to ensure compliance with cGMP requirements and other laws.
BLA submission and review
Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from pertinent preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. The submission of a BLA
requires payment of a substantial application user fee to FDA, unless a waiver or exemption applies, and the sponsor of an approved BLA is also subject to an annual program fee.
Once a BLA has been submitted, the FDA’s goal is to review standard applications within ten months after it accepts the application for filing, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed, or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review questions. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more treatment sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A Complete Response letter will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the Complete Response letter without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.
If regulatory approval of a product is granted, such approval will be granted for certain indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of the product outweigh its risks. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace.
Expedited development and review programs
FDA is authorized to expedite the review of BLAs in several ways. Under the fast-track program, a sponsor may request FDA to designate the product as a fast-track product if the product is intended to treat a serious or life-threatening condition and demonstrates the potential to address unmet medical needs. Fast-track designation has opportunities for frequent interactions with the review team during product development and, once a BLA is submitted, the product may be eligible for priority review. A fast-track product may also be eligible for rolling review, where the FDA may consider for review sections of the BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.
A product intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and review. A product can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all the fast-track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product, including involvement of senior managers.
Any marketing application for a biologic submitted to the FDA for approval, including a product with a fast-track designation and/or breakthrough therapy designation, may be eligible for other types of FDA programs intended to expedite the FDA review and approval process, such as priority review and accelerated approval. A product is eligible for priority review if it has the potential to provide a significant improvement in the treatment, diagnosis or prevention of a serious disease or condition compared to marketed products. For products containing new molecular entities, priority review designation means the FDA’s goal is to act on the marketing application within six months of the 60-day filing date (compared with ten months under standard review).
Additionally, products studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments.
Regenerative medicine advanced therapy, or RMAT, designation like breakthrough therapy designation, provides potential benefits that include more frequent meetings with FDA to discuss the development plan for the product candidate and eligibility for rolling review and priority review. Products granted RMAT designation may also be eligible for accelerated approval based on a surrogate or intermediate endpoint reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number of sites, including through expansion to additional sites.
Fast track designation, breakthrough therapy designation, priority review, accelerated approval, and RMAT designation do not change the standards for approval but may expedite the development or approval process.
Orphan drug designation
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease or condition will be recovered from sales in the United States for that drug or biologic. The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process.
If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity.
A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.
Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. Biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party
manufacturers. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.
The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:
|●||restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls;|
|●||fines, warning letters or holds on post-approval clinical studies;|
|●||refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product approvals;|
|●||product seizure or detention, or refusal of the FDA to permit the import or export of products;|
|●||consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;|
|●||mandated modification of promotional materials and labeling and the issuance of corrective information;|
|●||the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or|
|●||injunctions or the imposition of civil or criminal penalties.|
The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products.
Biosimilars and reference product exclusivity
The ACA includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-approved reference biological product. To date, several biosimilars have been licensed under the BPCIA, and numerous biosimilars have been approved in Europe. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.
Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products.
The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, recent government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects
of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.
Regulation and Procedures Governing Approval of Medicinal Products in the European Union
The process governing approval of medicinal products in the European Union generally follows the same lines as in the United States. It entails satisfactory completion of pharmaceutical development, nonclinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy of the medicinal product for each proposed indication. It also requires the submission to relevant competent authorities for clinical trials authorization and to the EMA or to competent authorities in European Union Member States for a marketing authorization application, or MAA, and granting of a marketing authorization by these authorities before the product can be marketed and sold in the European Union.
Clinical Trial Approval
Until December 2021, clinical trials in the European Union were approved under the Clinical Trials Directive 2001/20/EC and the Directive 2005/28/EC through national legislation of the member states. Under this system, an applicant obtained approval from the competent national authority of a European Union member state in which the clinical trial would be conducted or in multiple member states if the clinical trial was to be conducted in several member states. Additionally, the applicant could only start a clinical trial at a specific study site after the independent ethics committee has issued a favorable opinion. The CTA would be accompanied by an investigational medicinal product dossier with supporting information prescribed by Directive 2001/20/EC and Directive 2005/28/EC and corresponding national laws of the member states and further detailed in applicable guidance documents.
In December 2021, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which replaced the current Clinical Trials Directive 2001/20/EC. It overhauled the current system of approvals for clinical trials in the European Union. Specifically, the new regulation is directly applicable in all member states and aims at simplifying and streamlining the approval of clinical trials in the European Union. For instance, the new Clinical Trials Regulation provides for a streamlined application procedure via a single-entry point and strictly defined deadlines for the assessment of clinical trial applications.
In January 2022, Clinical Trials Directive (EC) No. 2001/20/EC and its national implementing legislation in the EU Member States was repealed and the New Clinical Trials Regulation became effective. The new Clinical Trials Regulation enables sponsors to submit one online application via a single online platform known as the Clinical Trials Information System (CTIS) for approval to run a clinical trial in several European countries, making it more efficient to carry out such multinational trials. The Regulation also makes it more efficient for EU Member States to evaluate and authorize such applications together, via the Clinical Trials Information System.
For the first year of implementation, until January 30, 2023, clinical trial sponsors could select whether to apply to start a clinical trial under the new Clinical Trials Regulations. After January 2023, clinical trial sponsors need to apply to start a clinical trial under the new Clinical Trials Regulations.
Orphan Drug Designation and Exclusivity
Regulation (EC) No. 141/2000 and Regulation (EC) No. 847/2000 provide that a product can be designated as an orphan drug by the European Commission if its sponsor can establish: that the product is intended for the diagnosis, prevention or treatment of (1) a life-threatening or chronically debilitating condition affecting not more than five in ten thousand persons in the European Union when the application is made, or (2) a life-threatening, seriously debilitating or serious and chronic condition in the European Union and that without incentives it is unlikely that the marketing of the drug in the European Union would generate sufficient return to justify the necessary investment.
An Orphan Drug Designation provides many benefits, including fee reductions, regulatory assistance and the possibility to apply for a centralized European Union marketing authorization. Marketing authorization for an
orphan drug leads to a ten-year period of market exclusivity. The market exclusivity period for the authorized therapeutic indication may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for Orphan Drug Designation because, for example, the product is sufficiently profitable not to justify market exclusivity.
To obtain a marketing authorization for a product under the European Union regulatory system, an applicant must submit an MAA, either to EMA using the centralized procedure or to competent authorities in European Union Member States using the other procedures (decentralized procedure, national procedure, or mutual recognition procedure).
The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid for all European Union member states as well as in the European Economic Area countries Iceland, Liechtenstein and Norway. Pursuant to Regulation (EC) No. 726/2004, the centralized procedure is compulsory for specific products, including for medicines produced by certain biotechnological processes, products designated as orphan medicinal products, advanced therapy products and products with a new active substance indicated for the treatment of certain diseases, including products for the treatment of cancer and auto-immune diseases. For products with a new active substance indicated for the treatment of other diseases and products that are highly innovative or for which the centralized procedure is in the interest of public health, the centralized procedure may be optional.
Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the EMA is responsible for conducting the assessment of a product to define its risk/benefit profile. Under the centralized procedure, the maximum timeframe for the evaluation of an MAA is 210 days, excluding clock stops when additional information or written or oral explanation is to be provided by the applicant in response to questions of the CHMP. Accelerated evaluation may be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from the point of view of public health and therapeutic innovation. If the CHMP accepts such a request, the time limit of 210 days will be reduced to 150 days, but it is possible that the CHMP may revert to the standard time limit for the centralized procedure if it determines that it is no longer appropriate to conduct an accelerated assessment.
Periods of Authorization and Renewals
A marketing authorization is valid for five years, in principle, and it may be renewed after five years based on a reevaluation of the risk benefit balance by the EMA or by the competent authority of the authorizing member state. To that end, the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months before the marketing authorization ceases to be valid. Once renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the competent authority decides on justified grounds relating to pharmacovigilance to proceed with one additional five-year renewal period.
