Risk Factors Full Breakdown - Total Risks 53
- Innovation / R&D - Risk 1Our clinical and pre-clinical research activities include the research and development of novel gene therapy product candidates. It will be difficult to predict the time and cost of development and of subsequently obtaining regulatory approval for any such gene therapy product candidates, or how long it will take to commercialize any gene therapy product candidates.
In addition to our ongoing gene therapy clinical trials, we intend to continue to identify and develop novel gene therapy product candidates as part of our pre-clinical research efforts. We have limited experience in developing gene therapy programs and cannot be certain that any gene therapy product candidates that we develop will successfully complete pre-clinical studies and clinical trials, or that they will not cause significant adverse events or toxicities. Any such results could impact our ability to develop a gene therapy product candidate, including our ability to enroll patients in our clinical trials. Furthermore, there is the potential risk of delayed adverse events following exposure to gene therapy products due to persistent biological activity of the genetic material or other components of products used to carry the genetic material, which may adversely affect our ability to obtain and maintain regulatory approvals for and commercialize any gene therapy products we may develop. In addition, to date, only a small number of gene therapy products have been approved in the US, Europe, Japan, or elsewhere, and regulatory requirements governing gene therapy products continue to evolve and may continue to change in the future. We may seek regulatory approval in territories outside the US, Europe, and Japan, which may have their own regulatory authorities along with frequently changing requirements or guidelines. The regulatory review committees and advisory groups in the US, Europe, Japan, and elsewhere, and any new guidelines they promulgate, may lengthen the regulatory review process, require us to perform additional studies, increase our development costs, lead to changes in regulatory positions and interpretations, delay or prevent approval and commercialization of our product candidates or lead to significant post-approval limitations or restrictions. Within the FDA, the Center for Biologics Evaluation and Research (CBER) regulates gene therapy products. Within CBER, the review of gene therapy and related products is consolidated in the Office of Therapeutic Products, and the FDA has established the Cellular, Tissue and Gene Therapies Advisory Committee to advise CBER on its reviews. CBER works closely with the National Institutes of Health (the NIH) in connection with the development of gene therapy. CBER has experienced leadership changes and broad layoffs and departures under the Trump Administration, which may slow review times. The FDA has published specific guidance documents with respect to the development and approval of gene therapy products. Amongst these guidance documents are final guidance documents that pertain to the development of gene therapies for the treatment of specific disease categories, including rare diseases of interest to Insmed, and to manufacturing and long-term follow-up issues relevant to gene therapy, among other topics. For example, the FDA issued a final guidance document in September 2021 describing the FDA's approach for determining whether two gene therapy products are the same or are different for the purpose of orphan-drug designation and orphan-drug exclusivity. On January 11, 2026, the FDA announced information about what the agency called its "flexible approach" to overseeing chemistry, manufacturing and control requirements for cell and gene therapies, although applicable requirements remain rigorous. The FDA has continued to issue additional draft and final guidance documents on the development and manufacture of gene therapy products. As we advance gene therapy product candidates, we will be required to consult with these regulatory authorities and advisory groups, and comply with applicable guidelines. If we fail to do so, we may be required to delay or discontinue development of certain of our product candidates. These additional processes may result in a review and approval process that is longer than we otherwise would have expected. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a potential product to market could decrease our ability to generate product revenue. Due to these factors, it is more difficult for us to predict the time and cost of gene therapy product candidate development, and we cannot predict whether the application of our approach to gene therapy, or any similar or competitive programs, will result in the identification, development and regulatory approval of any product candidates, or that the gene therapy programs of our competitors will not be considered better or more attractive or available in the market prior to ours. There can be no assurance that any development problems we experience in the future related to gene therapy product candidates will not cause significant delays or unanticipated costs, or that such development problems can be solved. We may also experience delays and challenges in achieving sustainable, reproducible and scalable production. Additionally, if a safety concern arises in connection with a gene therapy product from any sponsor, regulatory authorities might apply greater scrutiny to our gene therapy product candidates and any approved gene therapy products, and it might become more challenging to enroll patients in clinical trials and commercialize approved gene therapy products. Any of these factors may prevent us from completing our pre-clinical studies or clinical trials or commercializing any gene therapy product candidates we may develop on a timely or profitable basis, if at all.
- Innovation / R&D - Risk 2We may not be able to enroll enough patients to conduct and complete our clinical trials or retain a sufficient number of patients in our clinical trials to generate the data necessary for regulatory approval of our product candidates or to gain approval of the use of ARIKAYCE in the broader population of patients with MAC lung disease.
The completion rate of our clinical trials is dependent on, among other factors, the patient enrollment rate. Patient enrollment is a function of many factors, including: - Investigator identification and recruitment;- Regulatory approvals to initiate study sites;- Patient population size;- The nature of the protocol to be used in the trial;- Patient proximity to clinical sites;- Eligibility criteria for the trial;- Patient willingness to participate in the trial;- Discontinuation rates; and - Competition from other companies' potential clinical trials for the same patient population. Delays in patient enrollment for our clinical trials could increase costs and delay commercialization and sales, if any, of our products. Once enrolled, patients may elect to discontinue participation in a clinical trial at any time. If patients elect to discontinue participation in our clinical trials at a higher rate than expected, including with respect to our ENCORE trial, we may be unable to generate the data required by regulators for approval of our product candidates.
- Innovation / R&D - Risk 3If our clinical studies do not produce positive results or our clinical trials are delayed, or if serious side effects are identified during drug development, we may experience delays, incur additional costs and ultimately be unable to obtain regulatory approval for and successfully commercialize our product candidates in the US, Europe, Japan or other markets.
Before obtaining regulatory approval for the sale of our product candidates, we must conduct, at our own expense, extensive pre-clinical tests to demonstrate the safety of our product candidates in animals, and clinical trials to demonstrate the safety and efficacy of our product candidates in humans. If we experience delays in our clinical trials or other testing or the results of these trials or tests are not positive or are only modestly positive, including with respect to safety, we may: - Experience increased product development costs;- Be delayed in obtaining, or be unable to obtain, regulatory approval for one or more of our product candidates;- Obtain approval for indications or patient populations that are not as broad as intended or entirely different than those indications for which we sought approval or with labeling with boxed warnings or other warnings or contraindications;- Need to change the way the product is administered;- Be required to perform additional clinical trials to support approval or be subject to additional post-marketing testing requirements;- Have regulatory authorities withdraw, or suspend, their approval of the product or impose risk mitigation strategies such as a REMS or other restrictions on distribution;- Face a shortened patent protection period during which we may have the exclusive right to commercialize our products;- Have competitors that are able to bring similar products to market before us;- Be sued for alleged injuries caused to patients using our products; or - Suffer reputational damage. Such circumstances would impair our ability to commercialize our products and harm our business and results of operations. The risk of finding adverse side effects may be particularly heightened in the case of gene therapies. For instance, new gene copies may produce too much or too little of the desired protein or RNA, or the production of the desired protein or RNA may change over time. Because the treatment is irreversible, there may be challenges in managing side effects. Some adverse effects would not be able to be reversed or relieved and might require us to develop additional clinical safety procedures. Furthermore, new gene copies may disrupt other normal biological molecules and processes which could also result in undesirable adverse effects. Adverse side effects may also be experienced by patients as a result of the process for administering the therapy or related procedures. There have been several significant adverse side effects in gene therapy treatments in the past, including reported cases of leukemia, immune-mediated responses, and death seen in other trials. Gene therapy is still a relatively new approach to disease treatment and additional adverse side effects could develop. For instance, possible adverse side effects that could occur include immunologic-mediated reactions early after administration, which could substantially limit the effectiveness of the treatment, and could lead to further adverse side effects, possibly including organ failure or death. Additional manufacturing, clinical, and pre-clinical testing may be required, as well as additional analyses, assessments, and potential long-term patient and clinical study subject monitoring, beyond what is currently required, and sample testing and associated regulatory reporting. Serious adverse events in our clinical trials, or other clinical trials involving gene therapy products or our competitors' products, even if not ultimately attributable to the relevant product candidates, and the resulting publicity, any claims that gene therapy is unsafe, or gene therapy being unable to gain the acceptance of the public or the medical community may further adversely impact our product candidates in the form of increased government regulation, unfavorable public perception, lack of physician adoption, the need for additional testing or monitoring, potential regulatory delays, stricter labeling requirements, and a decrease in demand.
- Innovation / R&D - Risk 4Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available, may be interpreted differently if additional data are disclosed, and are subject to audit and verification procedures that may result in material changes in the final data.
From time to time, we may publicly disclose preliminary or topline data from our clinical trials, which may be based on a preliminary analysis of then-available data in a summary or topline format, and the results and related findings may change as more patient data become available, may be interpreted differently if additional data are disclosed at a later time and are subject to audit and verification procedures that could result in material changes in the final data. If additional results from our clinical trials are not consistent with topline data or other previously released data or are not viewed favorably, our ability to obtain approval for and commercialize our approved drug and drug candidates, our business, operating results, prospects, or financial condition may be harmed and our stock price may decrease. We also make assumptions, estimates, calculations, and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the preliminary or topline results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results,once additional data have been disclosed and/or are received and fully evaluated. Such 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, preliminary and topline data should be viewed with caution until the final data are available. We may also disclose interim data from our clinical trials. Interim data from clinical trials that we may complete 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. Differences between preliminary or interim data and final data could significantly harm our business prospects. In addition, blinded data may not be predictive of unblinded data. Further, other parties, 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 drug candidate or product, and our business in general. In addition, in regards to the information we publicly disclose regarding a particular study or clinical trial, such as topline data, you or others may not agree with what we determine is the material or otherwise appropriate information to include in such disclosure, and any information we determine not to disclose, or to disclose at a later date, such as at a medical meeting may ultimately be deemed significant with respect to future decisions, conclusions, views, activities, or otherwise regarding a particular drug, drug candidate, or our business. If the topline data that we report differ from actual results or are interpreted differently once additional data are disclosed at a later date, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for and commercialize our drug candidates, our business, operating results, prospects, or financial condition may be harmed or our stock price may decline.
- Innovation / R&D - Risk 5Pharmaceutical research and development is very costly and highly uncertain, and we may not succeed in developing product candidates in the future.
Product development in the pharmaceutical industry is an expensive, high-risk, lengthy, complicated, resource intensive process. In order to develop a product successfully, we must, among other things: - Identify potential product candidates;- Submit for and receive regulatory approval to perform clinical trials;- Design and conduct appropriate pre-clinical and clinical trials, including confirmatory clinical trials, according to good laboratory practices and good clinical practices and disease-specific expectations of the FDA and other regulatory bodies;- Select and recruit clinical investigators and subjects for our clinical trials;- Obtain and correctly interpret data establishing adequate safety of our product candidates and demonstrating with statistical significance that our product candidates are effective for their proposed indications, as indicated by satisfaction of pre-established endpoints;- Submit for and receive regulatory approvals for marketing; and - Manufacture the product candidates and device constituent parts according to cGMP and other applicable standards and regulations. There is a high rate of failure inherent in this process, and potential products that appear promising at early stages of development may fail for a number of reasons. Importantly, positive results from pre-clinical studies of a product candidate may not be predictive of similar results in human clinical trials, promising results from earlier clinical trials of a product candidate may not be replicated in later clinical trials, and observations from ongoing trials, including observations based on interim, preliminary, or blinded data, may not be representative of results after the trials are completed and all data are collected and analyzed. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving positive results in earlier stages of development and have abandoned development efforts or sought partnerships in order to continue development. In addition, there are many other difficulties and uncertainties inherent in pharmaceutical research and development that could significantly delay or otherwise materially impair our ability to develop future product candidates, including the following: - Conditions imposed by regulators, ethics committees or institutional review boards for pre-clinical testing and clinical trials relating to the scope or design of our clinical trials, including selection of endpoints and number of required patients or clinical sites;- Challenges in designing our clinical trials to support potential claims of superiority over current standard of care or future competitive therapies;- Restrictions placed upon, or other difficulties with respect to, clinical trials and clinical trial sites, including with respect to potential clinical holds or suspension or termination of clinical trials due to, among other things, potential safety or ethical concerns or noncompliance with regulatory requirements;- Delayed or reduced enrollment in clinical trials, high discontinuation rates or overly concentrated patient enrollment in specific geographic regions;- Failure by third-party contractors, contract research organizations (CROs), clinical investigators, clinical laboratories, or suppliers to comply with regulatory requirements or meet their contractual obligations in a timely manner;- Greater than anticipated cost of our clinical trials; and - Insufficient product supply or inadequate product quality. We cannot state with certainty when or whether our product candidates now under development will be approved or launched; whether, if initially granted, such approval will be maintained; whether we will be able to develop, license, or otherwise acquire additional products or product candidates; or whether our products, once launched, will be commercially successful. Failure to successfully develop future product candidates for any of these reasons may materially adversely affect our business, financial condition, results of operations and prospects and the value of our common stock.
- Innovation / R&D - Risk 6Our prospects are highly dependent on the success of our approved products, ARIKAYCE and BRINSUPRI. If we are unable to successfully market, commercialize and maintain approval for ARIKAYCE and BRINSUPRI, our business, financial condition, results of operations and prospects and the value of our common stock may be materially adversely affected.
Our long-term viability and growth depend on the successful commercialization of ARIKAYCE and BRINSUPRI. ARIKAYCE was approved in the US for the treatment of MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options in a refractory setting, as defined by patients who do not achieve negative sputum cultures after a minimum of six consecutive months of a multidrug background regimen therapy. Subsequently, ARIKAYCE was approved in Europe for the treatment of NTM lung infections caused by MAC in adults with limited treatment options who do not have CF, and in Japan for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatments with a multidrug regimen. We refer to NTM lung disease caused by MAC as MAC lung disease. BRINSUPRI was approved in the US in August 2025 as an oral, once-daily treatment for NCFB in adults and children 12 years and older, and in the EU in November 2025 for NCFB in adults and children 12 years or older with two or more exacerbations in the prior 12 months. We have invested and continue to invest significant efforts and financial resources in the commercialization of ARIKAYCE and BRINSUPRI. Our ability to continue to generate revenue from ARIKAYCE will depend heavily on successfully commercializing and obtaining full regulatory approval for ARIKAYCE from the FDA by conducting an appropriate confirmatory post-marketing study. Our ability to generate revenue from BRINSUPRI will depend heavily on successfully commercializing BRINSUPRI in the US and the EU as well as obtaining additional regulatory approvals outside of the US and the EU. In order to continue to commercialize ARIKAYCE and BRINSUPRI, we must continue to establish and maintain marketing, market access, sales and distribution capabilities on our own or make arrangements with third parties for its marketing, sale and distribution. We are commercializing ARIKAYCE in the US, Europe and Japan and BRINSUPRI in the US using our sales force, and we intend to use our sales force in any additional markets in which we commercialize BRINSUPRI, but we may not continue to be successful in these efforts. The establishment, development and maintenance of our own sales force is and will continue to be expensive and time-consuming. As a result, we may seek one or more partners to handle some or all of the sales and marketing of ARIKAYCE and/or BRINSUPRI in certain markets following approval by the relevant regulatory authority in those markets. In that case, we will be reliant on third parties to successfully commercialize ARIKAYCE and/or BRINSUPRI and will have less control over commercialization efforts than if we handled commercialization with our own sales force. However, we may not be able to enter into arrangements with third parties to sell ARIKAYCE and/or BRINSUPRI on favorable terms or at all. In the event that either our own marketing, market access, sales force or third-party marketing, and sales organizations are not effective, our ability to generate revenue would be adversely affected.
