We commenced operations in 2017, have no products approved for commercial sale and have not generated any revenue. In July 2022, we initiated a Phase 2 clinical trial for our lead product candidate, EDG-5506, and in September 2023, we initiated a Phase 1 clinical trial of our product candidate EDG-7500. 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.

Current 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 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

In addition, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors and risks frequently experienced by clinical-stage biopharmaceutical companies in rapidly evolving fields. We also may need to transition from a company with a research and development focus to a company capable of supporting commercial activities. We have not yet demonstrated an ability to successfully overcome such risks and difficulties, or to make such a transition. If we do not adequately address these risks and difficulties or successfully make such a transition, our business will suffer.

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 $100.2 million for the year ended December 31, 2023. As of December 31, 2023, we had an accumulated deficit of $244.8 million. We are advancing EDG-5506 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.

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 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.

As of December 31, 2023, we had $318.4 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. We filed on April 1, 2022, a shelf registration statement on Form S-3 with the SEC that became effective on May 5, 2022 and allows us to undertake various equity and debt offerings up to $400,000,000. On September 14, 2022, a prospectus supplement to the shelf registration statement pursuant to which we issued and sold $138.0 million of our common stock. On June 16, 2023, we entered into a Sales Agreement (Sales Agreement) with BofA Securities, Inc. (BofA Securities) under which we may offer and sell shares of common stock, having aggregate sales proceeds of up to $125,000,000 from time to time, through an “at the market offering” program (ATM Program). Effective January 19, 2024, we suspended and terminated the prospectus related to the ATM Program. On January 19, 2024, we filed an amendment to our shelf registration statement on Form S-3MEF with the SEC that increased the limit of our securities offerings by an additional $37,919,578. We then filed a prospectus supplement to the shelf registration statement on the same day pursuant to which we issued and sold $240.0 million of our common stock in the January 2024 Offering which closed on January 23, 2024. Although we do not have any availability under such shelf registration statement, we intend to in the future file a shelf registration statement for additional equity or debt offerings. 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

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, EDG-5506, 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 EDG-5506, 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.

In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (Code), 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, the United States recently 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. However, recently proposed tax legislation, if enacted, would restore the ability to deduct currently domestic research and development expenditures through 2025 and would retroactively restore this benefit for 2022 and 2023. 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.

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 of EDG-5506 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 of EDG-5506 and result in increased costs related to EDG-5506. Additionally, certain preclinical studies for our discovery research programs are conducted by CROs, which could be discontinued or delayed as a result of the pandemic. 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 for EDG-5506. In addition, our clinical trial sites could experience delays in collecting, receiving, and analyzing data from patients enrolled in our clinical trial for EDG-5506 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 EDG-7500, product candidates from our research program currently focused on cardiometabolic indications, or EDG-003, and our lead product candidate, EDG-5506. EDG-7500 is currently in a Phase 1 trial. We have paused the development of EDG-5440, having completed IND-enabling studies, given the favorable profile of EDG-5506 to date. 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.

Current 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 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.

Previous wording

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 EDG-5506, 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.

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, 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.

Previous 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 trial for EDG-5506, dose limiting somnolence was observed at the 135 mg level. In addition, in the MAD trial for EDG-5506, the most common adverse events were dizziness and somnolence, all of which were mild and transient. In the Phase 1b clinical trial, the most common adverse event was dizziness, which was mild and transient and was consistent with observations from the ARCH trial of EDG-5506 in adults with Becker. EDG-5506 or other product candidates may be used in pediatric populations for which safety concerns may be particularly scrutinized by regulatory agencies. In addition, if EDG-5506 is studied in combination with other therapies, it may exacerbate adverse events associated with the therapy. Patients treated with EDG-5506 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.

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. Although we have announced positive results from our preclinical studies and clinical trials, we do not know whether EDG-5506 or EDG-7500 will perform in current or future clinical trials as EDG-5506 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. 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.

Previous 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. Patients treated with our product candidates may also be undergoing other therapies and may be using other approved products or investigational new drugs, which can cause side effects or adverse events that are unrelated to our product candidates. As a result, assessments of efficacy can vary widely for a particular patient, and from patient to patient and site to site within a clinical trial. This subjectivity can increase the uncertainty of, and adversely impact, our clinical trial outcomes.

Previous wording

We completed enrollment of our open-label ARCH trial and DUNE Phase 2 exercise challenge study of EDG-5506 at a single clinical trial site. Our other Phase 2 clinical trials are being conducted at multiple sites. We have 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.

Current wording

For sevasemten trials, we completed our open-label ARCH trial (single site) and our CANYON Phase 2 clinical trial (multiple sites), as well as completed enrollment of the DUNE Phase 2 exercise challenge study (single site), GRAND CANYON, the pivotal cohort of our Phase 2 CANYON clinical trial in individuals with Becker (multiple sites), and the LYNX and FOX Phase 2 studies in Duchenne (multiple sites). 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. However, we may experience difficulty with enrollment and/or maintenance of patients in the ongoing enrollment of Part B and Part C of the Phase 2 trial.

Previous wording

We are developing product candidates for severe muscle diseases with limited patient pools from which to draw for clinical trials. Such trials may be difficult to enroll and the lack of data on these patients may negatively impact the approvability of EDG-5506. We also may encounter difficulties in identifying and enrolling subjects with a stage of disease appropriate for our planned clinical trials and monitoring such subjects adequately during and after treatment. We may not be able to initiate or continue clinical trials if we are unable to locate a sufficient number of eligible subjects to participate in the clinical trials required by the FDA or comparable foreign regulatory authorities. In addition, the process of finding and diagnosing subjects may prove costly. Further, the treating physicians in our clinical trials may also use their medical discretion in advising patients enrolled in our clinical trials to withdraw from our studies to try alternative therapies.

Approximately 70% of patients with Duchenne are treated with corticosteroids to manage the inflammatory component of the disease. EMFLAZA (deflazacort) is an FDA-approved corticosteroid marketed by PTC Therapeutics, Inc. and prednisone is also FDA-approved and is marketed by multiple companies. In March 2022, Santhera Pharmaceuticals in collaboration with ReveraGen Biopharma, commenced the new drug application (NDA) filing as a rolling submission for vamorolone, a steroid therapy for Duchenne. In October 2023, the FDA granted Agamree (vomorolone) approval in Duchenne patients 2 years and older and Catalyst Pharmaceuticals, Inc. will be commercializing this product in the US following its North America exclusive license deal with Santhera. In addition, there are four FDA conditionally approved exon skipping drugs: EXONDYS 51 (eteplirsen), AMONDYS 45 (casimersen) and VYONDYS 53 (golodirsen), which are naked 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

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 plans to engage with the FDA and submit an NDA in the future. 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 2024, the Committee for Medicinal Products for Human Use (CHMP) of the EMA delivered a negative opinion on the re-examination procedure for the conditional marketing authorization of Translarna. This is expected to result in the withdrawal of Translarna from the EMA markets. In June 2023, the FDA approved Sarepta’s Biologics License Application seeking accelerated approval of their microdystrophin gene therapy, Elevidys (delandistrogene moxeparvovec), for the treatment of ambulant individuals with Duchenne. In September 2023, Sarepta released the topline data from the Elevidys confirmatory study that missed its primary endpoint of NSAA change from baseline vs. placebo. Despite the miss on the primary endpoint, Sarepta filed for sBLA in December 2023 seeking label expansion for Elevidys without restrictions on age or ambulation status. Other companies focused on developing genetic based therapies for Duchenne that target dystrophin mechanisms include Pfizer Inc., Solid Biosciences Inc., Genethon, PepGen, Dyne Therapeutics, Avidity Biosciences, REGENXBIO, and Entrada Therapeutics. Gene editing treatments that are in preclinical development are also being pursued by Vertex and Sarepta Therapeutics.

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.

With EDG-7500, we expect to face competition from existing products and products in development. Current pharmaceutical treatment is intended to improve diastolic filling in both oHCM and nHCM and reduce LVOT in oHCM patients only. The goal of current therapies is to achieve meaningful symptom relief. Non-vasodilating beta blockers and non-dihydropyridine calcium channel blockers are the first-line therapies for symptomatic oHCM and nHCM patients. Commonly prescribed beta-blockers are atenolol, propranolol, and metoprolol. Verapamil and diltiazem are calcium channel blockers used in the treatment of symptomatic oHCM and nHCM. For oHCM patients who remain symptomatic, a sodium channel blocker with negative ionotropic drug properties may also be added, typically disopyramide (either Pfizer’s Norpace, marketed by Pfizer, or a generic form marketed by several companies).
