Risk Factors Full Breakdown - Total Risks 35
- Regulation - Risk 1Legislation, such as the Inflation Reduction Act, or IRA, and the One Big Beautiful Bill Act, or OBBA, and potential future legislation may increase the difficulty and cost for us to obtain regulatory approval of, and to commercialize our products and to obtain Medicare coverage by 3rd party plans and affect the prices we may obtain upon commercialization.
The regulations that govern, among other things, regulatory approvals, coverage, pricing and reimbursement for new drug products vary widely from country to country. In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay regulatory approval of our product candidates, restrict or regulate post-approval activities and affect our ability to successfully sell MYQORZO or any other drug candidates for which we obtain regulatory approval. For example, in August 2022, the Inflation Reduction Act, or IRA, was signed into law, which, among other things, includes prescription drug provisions that may impact product pricing including the potential for net price reductions and/or the ability to increase price beyond the level of inflation over the lifecycle of our products, and/or may increase our rebate obligation to Medicare. The IRA implements inflation rebates in Medicare when a drug's Average Manufacturer Price (AMP, in Part D) or Average Sale Price (ASP, in Part B) rises faster than the inflation index (CPI-U). In addition, the Part D drug benefit caps beneficiary spending at $2,000, eliminates the coverage gap for patients, and modifies, beginning in 2025, liabilities for drug manufacturers by replacing the 70% discount in the Coverage gap with a 10% discount in the Initial Coverage phase and a 20% discount in the Catastrophic phase. The IRA may also impact our ability to achieve broad coverage of our products by Medicare Plans as the IRA reduces the government's and beneficiaries' liability for drug spending while shifting costs to health plans and drug manufacturers. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. In addition, an executive order issued by the White House on May 12, 2025, [directs the Department of Health and Human Services ("HHS") to implement a "Most Favored Nation" drug pricing policy], and the recently-enacted One Big Beautiful Bill Act imposes new restrictions on funding for government health care programs and on individual eligibility for coverage under those programs, which may lead to lower reimbursements for drugs covered by those programs. More recently, HHS has begun announcing new drug payment models to lower drug prices for government health care program beneficiaries, such as the GUARD and GENEROUS models announced by the agency in late 2025. These models would use the prices other countries pay for drugs as benchmarks for determining whether manufacturers are required to offer additional rebates. We cannot be sure whether additional legislation or rulemaking related to these developments will be issued or enacted, or what impact, if any, such changes will have on the profitability of MYQORZO, or any of our drug candidates, if approved for commercial use, in the future. There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. However, we cannot predict the timing or substance of proposals that may be adopted in the future, particularly in light of the difficulty of advancing legislation through Congress. The continuing efforts of governments, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare, including by imposing price controls, may adversely affect the demand and/or potential sales for MYQORZO and our product candidates for which we obtain regulatory approval and our ability to set a price that we believe is fair for our products. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. We cannot predict the likelihood, nature, or extent of health reform initiatives that may arise from future legislation or administrative action and cannot predict the effect of any of such initiatives on our future financial results or the value of our common stock.
- Regulation - Risk 2Our relationships with customers, healthcare providers, clinical trial sites and professionals and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other laws and regulations. If we fail to comply with federal, state and foreign laws and regulations, including healthcare, privacy and data security laws and regulations, we could face criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
Healthcare providers, including physicians and third-party payors play a primary role in the recommendation and prescription of any drug candidates for which we may obtain marketing approval. Our arrangements with customers, healthcare providers and third-party payors anywhere in the world may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we develop, and may market, sell and distribute, our products for which we obtain marketing approval. Activities to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that government authorities will conclude that our business practices 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, exclusion from government funded healthcare programs, such as Medicare and Medicaid in the United States, and the curtailment or restructuring of our operations. Exclusion, suspension and debarment from government funded healthcare programs would significantly impact our ability to commercialize, sell or distribute any drug. If any of the physicians or other providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.
- Regulation - Risk 3Approved drug products remain subject to ongoing obligations, including continued regulatory review by the FDA and foreign regulatory agencies and REMS, all of which may result in significant expense and limit commercialization efforts of our drugs.
Any regulatory approvals that we or our partners receive for our drugs or drug candidates are subject to limitations on the indicated uses for which the drug may be marketed or require potentially costly post-marketing follow-up studies or compliance with a REMS program that includes ETASU. For example, MYQORZO is subject to a comprehensive REMS program that includes, among other things, restrictions and qualifications on pharmacies that dispense the drug and certification, record-keeping, ongoing monitoring and patient counseling obligations on physicians who prescribe the drug. In addition, in connection with the approval of MYQORZO the FDA requires the conduct of the following post-marketing studies: (i) a worldwide descriptive study that collects prospective and retrospective data in women exposed to MYQORZO during pregnancy to assess risks of pregnancy and maternal complications, and adverse effects on the developing fetus, the neonate, and the infant, as well as to assess infant outcomes through at least the first year of life and (ii) a milk-only lactation study in lactating women who have received MYQORZO to measure concentrations of MYQORZO in breast milk using a validated assay, as well as to assess the effects on the breastfed infant, if available, based on study population. In addition, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping for approved drugs remain subject to extensive regulatory requirements. The subsequent discovery of previously unknown problems with a drug, including adverse events of unanticipated severity or frequency, or the discovery that adverse events or toxicities observed in preclinical research or clinical trials that were believed to be minor constitute much more serious problems, may result in restrictions on the marketing of the drug or withdrawal of the drug from the market.
- Regulation - Risk 4If the FDA or comparable foreign regulatory authorities approve generic versions of MYQORZO, or any other potential products that receive marketing approval, or such authorities do not grant MYQORZO appropriate periods of data or market exclusivity before approving a generic version, sales of MYQORZO could be adversely affected.
Once an NDA is approved, the drug covered thereby becomes a "reference-listed drug" in the FDA's publication, "Approved Drug Products with Therapeutic Equivalence Evaluations." Manufacturers may seek marketing approval of generic versions of reference-listed drugs through submission of Abbreviated New Drug Applications ("ANDAs") in the United States. Generic drugs may be significantly less costly to bring to market than the reference-listed drug and companies that produce generic drugs are generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales of any branded product or reference-listed drug is typically lost to the generic drug. The FDA may not approve an ANDA or a 505(b)(2) NDA for a generic drug until any applicable period of non-patent exclusivity for the reference-listed drug has expired. The FDCA provides a period of five years of non-patent exclusivity for a new drug containing a new chemical entity. During the exclusivity period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted by another company for another version of such product candidate where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an approved NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages or strengths of an existing product candidate. This three-year exclusivity covers only the conditions associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for product candidates containing the original active agent for other conditions of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the nonclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. Manufacturers may seek to launch generic drugs following the expiration of the marketing exclusivity period, even if we still have patent protection for such drugs. Competition that MYQORZO, or any other potential product candidates, may face from generic drugs could materially and adversely impact our future revenue, profitability and cash flows and substantially limit our ability to obtain a return on the investments we have made in those products. Our future revenues, profitability and cash flows could also be materially and adversely affected and our ability to obtain a return on the investments we have made in MYQORZO or other product candidates may be substantially limited if MYQORZO, or any other potential products, product candidates, are not afforded the appropriate periods of non-patent exclusivity.
- Regulation - Risk 5The regulatory approval and marketing authorization process is expensive, time-consuming and uncertain and may prevent our partners or us from obtaining approvals to commercialize some or all of our drug candidates.
The research, testing, manufacturing, selling and marketing of drugs are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries. Neither we nor our partners are permitted to market our potential drugs in the United States until we receive approval of an NDA from the FDA. Obtaining NDA approval is a lengthy, expensive and uncertain process. The FDA and foreign regulatory agencies can delay, limit or deny approval of a drug candidate for many reasons, including, but not limited to, a determination that a drug candidate is not safe or effective, that the data from non-clinical testing and clinical trials is insufficient and that our partner's or the contract manufacturer's processes or facilities are not in compliance with GMP. Even if we receive regulatory approval to manufacture and sell a drug in a particular regulatory jurisdiction, other jurisdictions' regulatory authorities may not approve that drug for manufacture and sale. Regulatory approval of an NDA, NDA supplement or other marketing application for our drug candidates is never guaranteed. For example, our NDA for omecamtiv mecarbil for the treatment of HFrEF resulted in a complete response letter notwithstanding the fact that GALACTIC-HF met its primary efficacy endpoint. As our previously filed NDA for omecamtiv mecarbil illustrates, while we may submit marketing authorization applications for our drug candidates in the future, such applications may not lead to any regulatory approvals, or may result in requirements to conduct additional clinical trials prior to any potential approvals, which would increase our development costs and delay or preclude any revenue from commercial sales of our drug candidates.
- Regulation - Risk 6Disruptions at the FDA, including due to a reduction in the FDA's workforce and/or inadequate funding for the FDA, could prevent the FDA from performing normal functions on which our business relies, which could negatively impact our business.
The ability of the FDA to review and approve new products or review other regulatory submissions can be affected by a variety of factors, including statutory, regulatory and policy changes, inadequate government budget and funding levels, a reduction in the FDA's workforce and its ability to hire and retain key personnel. Disruptions at the FDA and other agencies may also increase the time to meet with and receive agency feedback, review and/or approve our submissions, conduct inspections, issue regulatory guidance, or take other actions that facilitate the development, approval and marketing of regulated products, which would adversely affect our business. For example, over the last several years the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities. Most recently, during the U.S. government shut down in October 2025, the FDA was not able to accept applications for new drugs, generics, biologics, biosimilars or medical devices that require payment of a user fee. In addition, government proposals to reduce or eliminate budgetary deficits may include reduced allocations to the FDA and other related government agencies. For example, the current United States administration established the now-disbanded Department of Government Efficiency, which implemented a federal government hiring freeze and announced certain additional efforts to reduce federal government employee headcount, including by eliminating 3,500 employees from the FDA, and the size of the federal government. The reductions in the FDA's workforce and budgetary pressures could significantly impact the ability of the FDA to timely review and process our regulatory submissions or take other actions critical to the marketing of any of our product candidates that are ultimately approved. Any delay in the acceptance, review or approval of our investigational new drug applications, clinical trial applications, marketing applications, facility inspections or lot-release/testing activities could delay or increase the cost of our clinical trials, manufacturing scale-up, product launches or post-approval changes, which could have a material adverse effect on our business.
