We have a limited operating history, some of our product candidates are early in development and we have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and likelihood of success and future viability.

Current wording

We have a limited operating history and while we are moving toward becoming a commercial-ready biopharmaceutical company, some of our product candidates are early in development and we have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and likelihood of success and future viability.

Previous wording

We are a clinical stage biopharmaceutical company with a limited operating history upon which you can evaluate our business and prospects. We are developing precision medicines for rare neuromuscular diseases which is an unproven and highly uncertain undertaking and involves a substantial degree of risk. We commenced operations in 2017, and while we are moving toward becoming a commercial-ready biopharmaceutical company, we have no products approved for commercial sale and have not generated any revenue. In July 2022, we initiated the first of four Phase 2 clinical trials for our product candidate, sevasemten, and we are enrolling Part B and Part C of a multipart Phase 2 clinical trial with our product candidate EDG-7500 for people with HCM. We have not yet initiated clinical trials for any other product candidate, including product candidates from our EDG-003 cardiometabolic discovery program. Since our inception in 2017, we have devoted substantially all of our focus and financial resources to discovering, identifying and developing potential product candidates, including advancing our development programs, conducting preclinical studies of our product candidates and initiating clinical trials, organizing and staffing our company, business planning, raising capital and securing related intellectual property rights.

We are a late-stage clinical biopharmaceutical company with a limited operating history upon which you can evaluate our business and prospects. We are developing precision medicines for rare neuromuscular diseases which is an unproven and highly uncertain undertaking and involves a substantial degree of risk. We commenced operations in 2017, and while we are moving toward becoming a commercial-ready biopharmaceutical company, we have no products approved for commercial sale and have not generated any revenue. In July 2022, we initiated the first of four Phase 2 clinical trials for our product candidate sevasemten, in April 2024, we began enrolling a multipart Phase 2 clinical trial with our product candidate EDG-7500 for people with hypertrophic cardiomyopathy (HCM), and in September 2025, we initiated a Phase 1 trial of healthy adults with our product candidate EDG-15400 with future disease target of heart failure with preserved ejection fraction (HFpEF). We have not yet initiated clinical trials for any other product candidate, including product candidates from our EDG-003 cardiometabolic discovery program.

Previous wording

Although we are moving toward becoming a commercial-ready biopharmaceutical company, we have not yet demonstrated our ability to obtain marketing approvals, manufacture a commercial-scale product or arrange for a third-party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. As a result, it may be more difficult for investors to accurately predict our likelihood of success and viability than it could be if we had a longer operating history.

Previous wording

We have incurred significant net losses since our inception, have not generated any revenue to date and have financed our operations principally through private placements of our convertible preferred stock and public offerings of our common stock. Our net loss was $133.8 million for the year ended December 31, 2024. As of December 31, 2024, we had an accumulated deficit of $378.6 million. We are advancing sevasemten and EDG-7500 in clinical development. Our other programs, including EDG-003, are in preclinical discovery and research stages. As a result, we expect that it will be several years, if ever, before we receive approval to commercialize a product and generate revenue from product sales. Even if we succeed in receiving marketing approval for and commercializing one or more of our approved product candidates, we expect that we will continue to incur substantial research and development and other expenses in order to discover, develop and market additional potential products.

Our net loss was $167.8 million for the year ended December 31, 2025. As of December 31, 2025, we had an accumulated deficit of $546.4 million. We are advancing sevasemten, EDG-7500, and EDG-15400 in clinical development. Our other programs, including EDG-003, are in preclinical discovery and research stages. As a result, we expect that it will be a couple of years, if ever, before we receive approval to commercialize a product and generate revenue from product sales. Even if we succeed in receiving marketing approval for and commercializing one or more of our approved product candidates, we expect that we will continue to incur substantial research and development and other expenses in order to discover, develop and market additional potential products.

Previous wording

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter such that a period-to-period comparison of our results of operations may not be a good indication of our future performance, particularly since we expect our expenses to increase if and when our product candidates progress through clinical development as product candidates in later stages of clinical development generally have higher development costs than those in earlier stages, primarily due to the increased size and duration of later-stage clinical trials. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue. Our

Current wording

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. For example, we anticipate that our general and administrative expenses will increase in the future as we scale our organization to support clinical advancement, regulatory readiness, and future commercial planning activities.

The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue. Our prior losses and expected future losses have had and will continue to have an adverse effect on our working capital, our ability to fund the development of our product candidates and our ability to achieve and maintain profitability and the performance of our stock.

Previous wording

Our business depends entirely on the successful discovery, development, regulatory approval and commercialization of product candidates. We have no products approved for commercial sale and do not anticipate generating any revenue from product sales for the next several years, if ever. Our ability to generate revenue and achieve profitability depends significantly on our ability, or any future collaborator’s ability, to achieve several objectives, including:

As of December 31, 2024, we had $470.2 million in cash, cash equivalents and marketable securities. We expect our current cash, cash equivalents and marketable securities will be sufficient to fund our current operating plan for at least the next 12 months. On May 10, 2024, we filed an automatic shelf registration statement on Form S-3ASR that allows us to undertake various equity and debt offerings. We additionally filed a prospectus supplement to the shelf registration statement and entered into a sales agreement with Leerink Partners LLC (Leerink Sales Agreement) on May 10, 2024, under which we may offer and sell shares of common stock, having aggregate sales proceeds of up to $175,000,000 from time to time, through an “at the market offering” program (Leerink ATM).

Pursuant to the automatic shelf registration statement, on April 3, 2025, we closed an underwritten registered direct offering of 9,935,419 shares of our common stock for net proceeds of $187.1 million after deducting underwriting discounts and commissions and offering expenses. We have not yet offered or sold any shares of common stock related to the Leerink ATM. Our estimate as to how long we expect our existing cash, cash equivalents and marketable securities to be able to continue to fund our operations is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned.

Previous wording

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception, and we expect our expenses to increase in connection with our ongoing activities, particularly as we conduct clinical trials of, and seek marketing approval for, sevasemten, EDG-7500, product candidates from our EDG-003 cardiometabolic discovery program, as well as develop our proprietary drug discovery platform. Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with sales, marketing, manufacturing and distribution activities. Our expenses could increase beyond expectations if we are required by the FDA, the EMA or other regulatory agencies to perform clinical trials or preclinical studies in addition to those that we currently anticipate. Other unanticipated costs may also arise. Because the design and outcome of our planned and anticipated preclinical studies and 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. We are not permitted to market or promote sevasemten, EDG-7500, product candidates from our EDG-003 cardiometabolic discovery program or any other product candidate before we receive marketing approval from the FDA. We also expect to incur costs associated with operating as a public company. Our cash, cash equivalents and marketable securities will not be sufficient for us to fund any of our product candidates through regulatory approval, and we will need to raise additional capital to complete the development and commercialization of our products. Accordingly, we will need to obtain substantial additional funding in order to continue our operations.

Until such time, if ever, as we can generate substantial revenues, we will be required to obtain further funding through public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources, which may dilute our stockholders or restrict our operating activities. As summarized in the risk factor entitled, “We will require substantial additional capital to finance our operations. If we are unable to raise such capital when needed, or on acceptable terms, we may be forced to delay, reduce and/or eliminate one or more of our research and drug development programs or future commercialization efforts.”, we have previously raised capital under our shelf registration statement that was filed on April 1, 2022 with the SEC that became effective on May 5, 2022 and was amended on January 19, 2024.

Our net operating loss (NOL) carryforwards may be unavailable to offset future taxable income because of restrictions under U.S. tax law. Our NOLs generated in tax years beginning before January 1, 2018 are only permitted to be carried forward for 20 taxable years under applicable U.S. federal tax law, and therefore could expire unused. Under tax legislation commonly referred to as the Tax Cuts and Jobs Act of 2017 (Tax Act) as amended by the Coronavirus Aid, Relief, and Economic Security Act, our federal NOLs generated in tax years beginning after December 31, 2017 may be carried forward indefinitely, but for taxable years beginning after December 31, 2020, the deductibility of federal NOLs generated in tax years beginning after December 31, 2017 is limited to 80% of our current year taxable income. Our state NOLs may be subject to similar or different limitations. As of December 31, 2024, we had available federal NOL carryforwards of approximately $146.3 million, of which $145.1 million do not expire, and state NOL carryforwards of approximately $155.6 million, of which $32.7 million do not expire.

In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” (generally defined as a cumulative change in the corporation’s ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period), the corporation’s ability to use its pre-change NOLs and certain other pre-change tax attributes to offset its post-change taxable income may be limited. Similar rules may apply under state tax laws. We may have experienced such ownership changes in the past, and we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which are outside our control. We have not conducted any studies to determine annual limitations, if any, that could result from such changes in the ownership of our stock. Our ability to utilize our NOLs and certain other tax attributes could be limited by an “ownership change” as described above and consequently, we may not be able to utilize a material portion of our NOLs and certain other tax attributes, which could have a material adverse effect on our cash flows and results of operations.

We are subject to tax laws, regulations, and policies of several taxing jurisdictions. Changes in tax laws, as well as other factors, could cause us to experience fluctuations in our tax obligations and effective tax rates and otherwise adversely affect our tax positions and/or our tax liabilities. For example, in August 2022, the United States enacted the Inflation Reduction Act of 2022, which imposes a 1% non-deductible excise tax on certain stock buybacks and a 15% alternative minimum tax on global adjusted financial statement income. In addition, beginning in 2022, the Tax Act eliminated the option to deduct research and development expenditures currently and requires taxpayers to capitalize and amortize them over five or fifteen years, and this requirement may impact our effective tax rate and our cash tax liability in future years. When and if we achieve profitability, these changes may cause us to pay federal income taxes earlier than under prior law and may increase our total federal tax liability attributable to orphan drug programs and other research and development activities. Further, many countries, and organizations such as the Organization for Economic Cooperation and Development have proposed implementing changes to existing tax laws, including a proposed 15% global minimum tax that has been and is being adopted by several countries, with implementation beginning in 2024. Any of these developments or changes in U.S. federal, state, or international tax laws or tax rulings could adversely

On July 4, 2025, the U.S. federal tax legislation commonly referred to as the One Big Beautiful Bill Act (the OBBB Act) was enacted, which makes a number of changes to U.S. federal income tax law, including permanently suspending the requirement to capitalize and amortize domestic research and development expenditures and permitting such deductions on a current basis. The OBBB Act did not have a material impact on us. Further, many countries, and organizations such as the Organization for Economic Cooperation and Development (the OECD) have proposed implementing changes to existing tax laws, including a proposed 15% global minimum tax (Pillar Two) that has been implemented by several countries in 2024 and is being considered for implementation by other jurisdictions. On January 5, 2026, the OECD announced a “side-by-side” elective safe harbor that exempts U.S.-parented multinational entities from some of the Pillar Two rules (including the fifteen percent global minimum tax) for fiscal years beginning on or after January 1, 2026. Any of these developments or changes in U.S. federal or state or non-U.S. tax laws or tax rulings could adversely affect our effective tax rate and our operating results.

Additionally, certain third parties with whom we engage, including our collaborators, contract organizations, third-party manufacturers, suppliers, clinical trial sites, regulators and other third parties with whom we conduct business may adjust their operations in light of the COVID-19 pandemic or other public health emergencies. If these third parties experience shutdowns or continued business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively impacted. For example, we experienced delays in trial initiation for our Phase 1 clinical trial ofsevasemten and switched from an international third-party manufacturer to a third-party manufacturer based in the United States to minimize manufacturing supply chain disruptions as a result of COVID-19. Changing our third-party manufacturer could result in delays in our manufacturing supply chain which could delay or otherwise impact our development ofsevasemten and result in increased costs related tosevasemten. Additionally, certain preclinical studies for our discovery research programs are conducted by CROs, which could be discontinued or delayed as a result of public health emergencies. We could also experience delays if our suppliers are delayed in delivering raw materials to our third-party manufacturers. For example, we experienced delays in enrolling patients for our Phase 1 clinical trial forsevasemten. In addition, our clinical trial sites could experience delays in collecting, receiving, and analyzing data from patients enrolled in our clinical trial forsevasemten due to limited staff at such sites, limitation or suspension of on-site visits by patients, or patients’ reluctance to visit the clinical trial sites during the pandemic. As a result, research and development expenses and general and administrative expenses may vary significantly if there is an increased impact from COVID-19 or other public health emergencies on the costs and timing associated with the conduct of our clinical trial and other related business activities.

Previous wording

Our future operating results are dependent on our ability to successfully develop, obtain regulatory approval for and commercialize product candidates from our research program currently focused on cardiometabolic indications, or EDG-003, and our lead product candidates, sevasemten and EDG-7500. Sevasemten is currently being studied in multiple Phase 2 clinical trials and EDG-7500 is currently in a multipart Phase 2 trial. However, research and development related to novel therapeutics is inherently risky. A product candidate can unexpectedly fail at any stage of preclinical and/or clinical development. The historical failure rate for product candidates is high due to risks relating to safety, efficacy, clinical execution, changing standards of medical care and other unpredictable variables. The results from preclinical testing or early clinical trials of a product candidate may not be predictive of the results that will be obtained in later stage clinical trials of the product candidate.

Although we have announced positive results from our preclinical studies and clinical trials, our product candidates’ risk of failure is high and it is impossible to predict when or if sevasemten, EDG-7500, product candidates from our EDG-003 cardiometabolic discovery program or any other product candidate that we develop will prove effective or safe in humans or will receive marketing approval. Before obtaining marketing approval from the FDA, EMA or other comparable foreign regulatory authorities for the sale of our product candidates, we must complete preclinical development and extensive clinical trials to demonstrate with substantial evidence the safety and efficacy of such product candidates.

Although we have announced positive results from our preclinical studies and clinical trials, our product candidates’ risk of failure is high and it is impossible to predict when or if sevasemten, EDG-7500, EDG-15400, product candidates from our EDG-003 cardiometabolic discovery program or any other product candidate that we develop will prove effective or safe in humans or will receive marketing approval. Before obtaining marketing approval from the FDA, EMA or other comparable foreign regulatory authorities for the sale of our product candidates, we must complete preclinical development and extensive clinical trials to demonstrate with substantial evidence the safety and efficacy of such product candidates.

Previous wording

Clinical testing is expensive, difficult to design and implement, can take many years to complete and its ultimate outcome is uncertain. We cannot guarantee that any of our clinical trials will be conducted as planned or completed on schedule, or at all. Clinical trials can fail at any stage of testing and failure may result from a multitude of factors, including, among other things, flaws in study design, dose selection issues, placebo effects, patient enrollment criteria and failure to demonstrate favorable safety or efficacy traits. The outcome of preclinical studies and early-stage clinical trials may not be predictive of the success of later clinical trials. For example, the primary endpoint of the GRAND CANYON cohort may not be met even though the endpoint trended towards improvement as a secondary endpoint in the earlier cohorts of the CANYON trial, and the trends observed so far in the CANYON trial may not be seen and or may not be statistically significant in the GRAND CANYON cohort. In addition, our product candidates may fail to show the desired safety and efficacy in clinical development despite positive results in preclinical studies or having successfully advanced through initial clinical trials. We may also discover that the half-life of our product candidates renders them unsuitable for the therapeutic applications we have chosen. As a result, we cannot assure you that any clinical trials that we conduct will demonstrate consistent or adequate efficacy and safety to support marketing approval.

In addition, many of the factors that cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Any delays to our clinical trials that occur as a result could shorten any period during which we may have the exclusive right to commercialize our product candidates and our competitors may be able to bring products to market before we do, and the commercial viability of our product candidates could be significantly reduced.

(SAD) trial forsevasemten, dose limiting somnolence was observed at the 135 mg level. In addition, in the multiple ascending dose (MAD) trial forsevasemten, the most common adverse events were dizziness and somnolence, all of which were mild and transient. In the ARCH trial of sevasemten in adults with Becker, the most common adverse events were dizziness, fall, and arthralgia, which were mild and transient. Sevasemten or other product candidates may be used in pediatric populations for which safety concerns may be particularly scrutinized by regulatory agencies. In addition, ifsevasemten is studied in combination with other therapies, it may exacerbate adverse events associated with the therapy. Patients treated with sevasemten or our other product candidates may also be undergoing other therapies which can cause side effects or adverse events that are unrelated to our product candidate but may still impact the success of our clinical trials. The inclusion of critically ill patients in our clinical trials may result in deaths or other adverse medical events due to other therapies or medications that such patients may be using or due to the gravity of such patients’ illnesses, which could occur either during the course of our clinical trials or after participating in such clinical trials.

Current wording

Patients in our ongoing and planned clinical trials may in the future suffer other adverse events or other side effects not observed in our preclinical studies or previous clinical trials. For example, in the single ascending dose (SAD) trial forsevasemten, dose limiting somnolence was observed at the 135 mg level. In addition, in the multiple ascending dose (MAD) trial forsevasemten, the most common adverse events were dizziness and somnolence, all of which were mild and transient. In the ARCH trial of sevasemten in adults with Becker, the most common adverse events were dizziness, fall, and arthralgia, which were mild and transient. No new safety concerns have been observed in either the adult or adolescent patient populations of the CANYON trial, including the GRAND CANYON pivotal cohort, or the MESA open label extension that is providing continued access to sevasemten to participants with Becker who were previously enrolled in ARCH, or completed CANYON, including the GRAND CANYON pivotal cohort, or DUNE. In Part B and Part C of the Phase 2 CIRRUS-HCM trial of EDG-7500 in participants with HCM, the most frequently reported adverse events were dizziness, upper respiratory tract infection and atrial fibrillation (AF), nearly all of which were considered mild to moderate in severity. Sevasemten or other product candidates may be used in pediatric populations for which safety concerns may be particularly scrutinized by regulatory agencies. In addition, ifsevasemten is studied in combination with other therapies, it may exacerbate adverse events associated with the therapy.

If further serious adverse events or other side effects are observed in any of our current or future clinical trials, we may have difficulty recruiting patients to the clinical trials, patients may drop out of our trials, or we may be required to abandon the trials or our development efforts of that product candidate altogether. We, the FDA, EMA, other comparable regulatory authorities or an IRB may suspend clinical trials of a product candidate at any time for various reasons, including a belief that subjects in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics developed in the biotechnology industry that initially showed therapeutic promise in early-stage trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance due to its tolerability versus other therapies. Any of these developments could materially harm our business, financial condition and prospects. Further, if any of our product candidates obtains marketing approval, toxicities associated with such product candidates previously not seen during clinical testing may also develop after such approval and lead to a requirement to conduct additional clinical safety trials, additional contraindications, warnings and precautions being added to the drug label, significant restrictions on the use of the product or the withdrawal of the product from the market. We cannot predict whether our product candidates will cause toxicities in humans that would preclude or lead to the revocation of regulatory approval based on preclinical studies or early stage clinical trials.

We will be required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are safe and effective for use in a diverse population before we can seek marketing approvals for their commercial sale. Success in preclinical studies and early-stage clinical trials does not mean that future clinical trials will be successful. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. Although we have announced positive results from our preclinical studies and clinical trials, we do not know whether sevasemten or EDG-7500 will perform in current or future clinical trials assevasemten has performed in preclinical studies or earlier clinical trials, nor do we know whether any product candidate in our EDG-003 cardiometabolic discovery program will perform in current or future preclinical studies or future clinical trials as it has in prior preclinical studies. For example, the primary endpoint of the GRAND CANYON cohort may not be met even though the endpoint trended towards improvement as a secondary endpoint in the earlier cohorts of the CANYON trial, and the trends observed so far in the CANYON trial may not be seen and or may not be statistically significant in the GRAND CANYON cohort. Product candidates in clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA, EMA and other comparable foreign regulatory authorities despite having progressed through preclinical studies. Regulatory authorities may also limit the scope of later-stage trials until we have demonstrated satisfactory safety, which could delay regulatory approval, limit the size of the patient population to which we may market our product candidates, or prevent regulatory approval.

Current wording

In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, differences in and adherence to the dose and dosing regimen and other trial protocols and the rate of dropout among clinical trial participants.

We have also initiated an industry-sponsored, global, prospective registry investigating the natural history of adults with Becker aged 18 years and older. However, we may not be successful in achieving our goal of establishing natural history reference data points and identifying future eligibility for recruitment into our planned registrational trial in Becker. For EDG-7500 trials, we completed the Phase 1 trial in healthy subjects and the Part A single-dose arm of the multipart Phase 2 Cirrus-HCM trial in patients with oHCM.

In addition, there are four exon skipping drugs which are marketed under an accelerated approval pathway from the FDA: EXONDYS 51 (eteplirsen), AMONDYS 45 (casimersen) and VYONDYS 53 (golodirsen), which are naked phosphorodiamidate morpholino oligomers (PMOs) approved for the treatment of Duchenne patients amenable to Exon 51, Exon 45 and Exon 53 skipping, respectively, and are marketed by Sarepta Therapeutics, Inc., and VILTEPSO (vitolarsen), a naked PMO approved for the treatment of Duchenne patients amenable to Exon 53 skipping, which is marketed by Nippon Shinyaku Co. Ltd. In May 2024, Nippon Shinyaku Co. Ltd. announced that no statistical significance was observed between the treatment group and the placebo group in VILTEPSO’s confirmatory study. This result may affect VILTEPSO’s accelerated FDA approval. In June 2022, PTC Therapeutics presented new topline results with Translarna (ataluren), for patients with nonsense mutation Duchenne, a subset of the disease that impacts between 10% and 15% of patients. It remains unclear if the data will lead to FDA approval of Translarna, for which the company resubmitted the NDA in October 2024. Translarna has been conditionally approved in the European Union and Brazil for ambulatory patients aged 2 years and older with Duchenne resulting from a nonsense mutation in the dystrophin gene. However, in January and June 2024, the Committee for Medicinal Products for Human Use of the EMA delivered negative opinions on the re-examination procedure for the conditional marketing authorization of Translarna. This may result in the withdrawal of Translarna from the EMA markets.

However, in March 2025, the European Commission adopted the negative opinions issued by the Committee for Medicinal Products for Human Use of the EMA for the renewal of conditional marketing authorization of Translarna. While this action effectively removes Translarna’s marketing authorization in the European Economic Area, individual countries within the EU can leverage existing legislation to allow continued use of Translarna. In February 2026, PTC Therapeutics withdrew its application to the FDA for Translarna in nonsense mutation Duchenne after receiving feedback on its filing.

Current wording

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer side effects, are more convenient, have a broader label, are marketed more effectively, are more widely reimbursed or are less expensive than any products that we may develop. Our competitors also may obtain marketing approval from the FDA, EMA or other comparable foreign regulatory authorities 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. Even if the product candidates we develop achieve marketing approval, they may be priced at a significant premium over competitive products if any have been approved by then, resulting in reduced competitiveness. Technological advances or products developed by our competitors may render our technologies or product candidates obsolete, less competitive or not economical. If we are unable to compete effectively, our opportunity to generate revenue from the sale of our products we may develop, if approved, could be adversely affected.
