Added paragraphs (1)

Current report

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for clinical testing, as well as for manufacture of any products that we may commercialize, if approved. Our contract manufacturing organization is located in the United Kingdom and manufactures our preclinical materials and supplies. Additionally, several of our suppliers are located outside of the United States. We also rely on specialized laboratory equipment, supplies, materials, and precursor compounds, all or part of which we believe may be ultimately sourced from multiple countries outside the United States, to advance our research and development efforts.

Previous report

In our initial Phase 1 clinical trial for SZN-043, treatment-related adverse events have been observed, and if these findings are present in patients with severe alcohol-associated hepatitis and do not represent acceptable safety, we could require additional capital to complete our clinical trial and development efforts for SZN-043 or we may need to delay or abandon development of SZN-043.

Previous report

We have conducted our clinical trial for our product candidate outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case its development plans will be delayed, which could materially harm its business.

Previous report

The Phase 1a clinical trial for SZN-043 was completed in February 2024, but Grade 1 and 2 treatment-related asymptomatic transaminase elevations were present in several subjects dosed with SZN-043. The transaminase elevations for these subjects resolved spontaneously, and no serious adverse events were observed during the study. We intend to further analyze available clinical data and monitor future clinical studies to understand and mitigate, if possible, for these observations. If these observations are present and represent unacceptable safety in the intended population of patients with severe alcohol-associated hepatitis, or AH, we may need to pause the trials to perform additional pre-clinical experiments, causing delays in our development plans and requiring additional capital to resume and complete our development efforts and clinical trials for SZN-043. If we are unable to safely continue the trial for SZN-043 and resolve these observations, development of SZN-043 may be substantially delayed or abandoned and adversely affect our financial condition and results of operations.

Previous report

Members of our management team have limited experience in managing the day-to-day operations of a public company and, as a result, we may incur additional expenses associated with the management of our company.

Previous report

Members of our management team have limited experience in managing the day-to-day operations of a public company. As a result, we may need to obtain outside assistance from legal, accounting, investor relations, or other professionals that could be more costly than planned. We also plan to hire additional personnel to comply with additional SEC reporting requirements. These compliance costs will make some activities significantly more time-consuming and costly. If we lack cash resources to cover these costs in the future, our failure to comply with reporting requirements and other provisions of securities laws could negatively affect our stock price and adversely affect our potential results of operations, cash flow and financial condition.

Previous report

From time to time, we may implement organizational changes to pursue greater efficiency and realign our business and strategic priorities. In January 2023, we completed certain restructuring actions, or the January Restructuring Plan, designed to reduce operating costs and continue advancing our ongoing commitment to profitable growth, including an initial reduction of the overall workforce by approximately 25%. In July 2023, we implemented another restructuring plan, or the July Restructuring Plan, to reduce our overall workforce by a total of approximately 38% in an effort to better align our workforce with our business needs and focus our capital resources on clinical trials of our product candidates. We may encounter challenges in the execution of these efforts, and these challenges could impact our financial results.

Previous report

Although we believe that our organizational efforts will further reduce our operating costs, we cannot guarantee that the restructuring plans will achieve or sustain the targeted benefits, or that the benefits, even if achieved, will be adequate to meet our long-term profitability and operational expectations. As a result of these actions, we will incur additional charges in the near term, including those related to employee transition, severance payments, and employee benefits. Additional risks associated with the continuing impact of our organizational charges include employee attrition beyond our intended reduction-in-force and adverse effects on employee morale (which may also be further exacerbated by actual or perceived declining value of equity awards), diversion of management attention, adverse effects to our reputation as an employer (which could make it more difficult for us to hire new employees in the future), and potential failure or delays in the development of our product candidates due to the loss of qualified employees. If we do not realize the expected benefits of our restructuring efforts on a timely basis or at all, our business, results of operations and financial condition could be adversely affected.

Previous report

We have conducted our clinical trial for our product candidate outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case its development plans will be delayed, which could materially harm its business.

Previous report

We have conducted and may further conduct clinical trials for our product candidate outside the United States. For example, we have conducted the Phase 1 trial of SZN-043 in New Zealand. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of these data is subject to certain conditions imposed by the FDA. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless (i) those data are applicable to the U.S. population and U.S. medical practice; (ii) the studies were performed by clinical investigators of recognized competence; and (iii) the data are considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. For studies that are conducted only at sites outside of the United States and not subject to an IND, the FDA requires the clinical trial to have been conducted in accordance with GCPs, and the FDA must be able to validate the data from the clinical trial through an on-site inspection if it deems such inspection necessary. For such studies not subject to an IND, the FDA generally does not provide advance comments on the clinical protocols for the studies, and therefore there is an additional potential risk that the FDA could determine that the study design or protocol for a non-U.S. clinical trial was inadequate, which could require us to conduct additional clinical trials. There can be no assurance the FDA will accept data from clinical trials conducted outside of the United States. If the FDA does not accept data from our clinical trials of our product candidates, it would likely result in the need for additional clinical trials, which would be costly and time consuming and delay or permanently halt our development of our product candidates.

Previous report

Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of Our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction or permanently halt our development of our product candidates.

Previous report

In April 2024, we entered into a securities purchase agreement with certain institutional investors and management and issued and sold in a private placement: (i) 1,091,981 shares of common stock, (ii) pre-funded warrants to purchase up to 40,000 shares of common stock, and (iii) warrants to purchase up to 11,136,106 shares of common stock. A significant portion of these warrants may only be exercised in the event we meet certain clinical development milestones, which include patient enrollment. If we achieve these milestones and the warrants are exercised, it will result in significant dilution to our stockholders. In the alternative, we may not achieve these milestones, in which event we will be required to seek alternative sources of financing to continue the clinical development of our product candidates. Please see Notes 9, 10 and 11 to the unaudited condensed consolidated financial statements for further information regarding the private placement and the terms of the warrants. In addition, outstanding options may be exercised and restricted stock units may vest resulting in the issuance of additional shares of common stock, which will result in further dilution to our stockholders.

Previous wording

We are a clinical stage biopharmaceutical company with a history of losses. Since our inception, we have devoted substantially all of our resources to research and development, preclinical studies, clinical trials, building our management team and building our intellectual property portfolio, and have incurred significant operating losses. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies and clinical trials and the regulatory approval process for our current and potential future product candidates.

Previous wording

We expect our net losses to increase substantially as our lead product candidate, SZN-043, advances through clinical development. However, the amount of our future losses is uncertain. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, continuing clinical trials for SZN-043, successful development and testing of SZN-413 through our partnership with Boehringer Ingelheim International GmbH, or BI, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or our current and potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material and adverse effect on our business, financial condition, results of operations and prospects.

Previous wording

The development of biopharmaceutical product candidates is capital-intensive. If SZN-043 or potential future product candidates advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We have used substantial funds to develop our Wnt therapeutics platform, SZN-043 and other product candidates and we will require significant funds to continue to develop our platform, continue the clinical trial for SZN-043 and to conduct further research and development, including preclinical studies and clinical trials.

Previous wording

To date, we have primarily financed our operations through the sale of equity securities. Until such time as we can generate sufficient revenue from sales of our product candidates, if ever, we expect to finance our operations through public or private equity offerings, debt financings or other capital sources, including government grants, potential collaborations with other companies or other strategic transactions. In February 2022, we entered into a purchase agreement and a registration rights agreement with Lincoln Park Capital Fund, LLC, or Lincoln Park, pursuant to which we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $50.0 million of our common stock from time to time over a 36-month period, subject to certain conditions and limitations. We may not be able to receive any or all of the funds from Lincoln Park because of the limitations, restrictions, requirements, events of default and other provisions contained in the purchase agreement that could limit our ability to cause Lincoln Park to purchase our common stock. If our stock price decreases, we also may not be able to sell shares to Lincoln Park at all or in amounts sufficient to obtain necessary financing. In December 2022, we entered into an at-the-market sales agreement with Guggenheim Securities, LLC, or Guggenheim, in connection with a shelf registration statement on Form S-3 filed in December 2022, to issue and sell our common stock with an aggregate maximum offering price of $23.0 million under an at-the-market offering program. To date we have not sold any shares of common stock under the sales agreement. Given the volatility in the capital markets, we may not be willing or able to raise equity capital through such at-the-market offering. We may, therefore, need to turn to other sources of funding that may have terms that are not favorable to us, or further reduce our business operations due to capital constraints.

Current wording

Our product candidates that are tested in humans may not demonstrate the safety, purity and potency, or efficacy, necessary to become approvable or commercially viable.

Previous wording

We may ultimately discover that SZN-043 and SZN-413 do not possess certain properties that we believe are beneficial for therapeutic effectiveness and safety. For example, although SZN-043 exhibited encouraging results in animal studies, they may not demonstrate the same properties in humans and may interact with human physiology in unforeseen, ineffective or harmful ways, as shown by the observations of asymptomatic transaminase elevations discussed above. As a result, we may never succeed in developing a marketable product based on any of our current or future product candidates. If SZN-043, SZN-413 or any of our potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could require us to change our focus and approach to antibody-based discovery and development and materially and adversely affect our business, financial condition, results of operations and prospects.

Previous wording

A key element of our strategy is to use and expand our Wnt therapeutics platform to discover and develop a portfolio of Wnt product candidates that can facilitate the repair and/or regeneration of damaged tissue for patients suffering from a variety of severe diseases. Although our research and development efforts to date have resulted in the discovery and development of SZN-043, SZN-413 and other potential product candidates, our current product candidates may not be safe or effective therapeutics and we may not be able to develop any successful product candidates. Our platform is evolving and may not reach a state at which building a pipeline of product candidates is possible. Even if we are successful in building our pipeline of product candidates, the potential product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable toxicity or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. Observations of asymptomatic transaminase elevations in clinical trial of SZN-043 could also impair our ability to build and expand our Wnt platform if we are unable to successfully resolve those observations. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

Previous wording

Undesirable side effects caused by SZN-043, SZN-413 or any potential future product candidate could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. It is also possible that there will be side effects associated with the testing or use of our product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of these side effects. In such an event, our trials could be suspended or terminated and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. For example, certain researchers have noted that therapeutics targeting the Wnt pathway may lead to tumor formation or proliferation as a result of the downstream impacts of Wnt signaling. To date, we have not observed any such tumor formation with SZN-043 in our preclinical toxicology studies and clinical trial, but there can be no guarantee that our current or future product candidates will not result in tumor formation. Any of these occurrences or failure to resolve the findings related to SZN-043 may materially and adversely affect our business and financial condition and impair our ability to generate revenues.

Previous wording

The terms of any financing, including our potential financing through Lincoln Park and the at-the-market sales agreement with Guggenheim, may adversely affect the holdings or the rights of our stockholders, and the issuance of additional securities by us, whether equity or debt, or the market perception that such issuances are likely to occur, could cause the market price of our common stock to decline. To the extent that we raise additional capital through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our current and potential future product candidates, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we raise any additional capital through public or private equity or convertible debt offerings, including through any sales of common stock to Lincoln Park or under the at-the-market sales agreement with Guggenheim, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

Because we have limited financial and managerial resources, we intend to focus our efforts on specific research and development programs, including clinical development of SZN-043 and SZN-413. As a result, we may forgo or delay pursuit of other opportunities, including with potential future product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial product candidates or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaborations, licensing or other royalty arrangements in cases in which we would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

Current wording

We rely on third parties to conduct our preclinical studies and clinical trials, and those third parties may not perform satisfactorily.

Previous wording

We rely on third-party contract manufacturers for our preclinical and future clinical trial product materials and supplies. We do not produce our product candidates in quantities sufficient for preclinical and clinical development, and we do not currently own manufacturing facilities for producing such supplies. Furthermore, some of our manufacturers represent our sole source of supplies of preclinical and future clinical development materials, including our source for the manufacture of SZN-043. Although our current contract manufacturer has multiple sites capable of producing our products (both drug substance and drug product), we cannot assure you that its preclinical or future clinical development product supplies and commercial supplies will not be limited or interrupted, especially with respect to our sole source third-party manufacturing and supply collaborators, or will be of satisfactory quality or continue to be available at acceptable prices. In particular, any replacement of our manufacturers could require significant effort and expertise because there may be a limited number of qualified replacements. For our current and future sole source third-party manufacturing and supply collaborators, we may be unable to negotiate binding agreements with them or find replacement manufacturers to support our preclinical and future clinical activities at commercially reasonable terms in the event that their services to us become interrupted for any reason. We do not always have arrangements in place for a redundant or second-source supply for our sole source vendors in the event they cease to provide their products or services to us or do not timely provide sufficient quantities to us. Establishing additional or replacement sole source vendors, if required, may not be accomplished quickly. Any delays resulting from manufacturing or supply interruptions associated with our reliance on third-party manufacturing and supply collaborators, including those that are sole source, could impede, delay, limit or prevent our drug development efforts, which could harm our business, result of operations, financial condition and prospects.

Our third-party manufacturers may be unable to successfully scale manufacturing of SZN-043 or potential future product candidates in sufficient quality and quantity, which would delay or prevent us from developing our current and future product candidates and, if approved, commercializing product candidates.

Current wording

Our third-party manufacturers may be unable to successfully scale manufacturing of our lead product candidates in sufficient quality and quantity, which would delay or prevent us from developing our current and future product candidates and, if approved, commercializing product candidates.

Previous wording

In order to conduct clinical trials for SZN-043 as well as any potential future product candidates or commercialize, we will need to manufacture large quantities of these product candidates. We may continue to and currently expect to use third parties for our manufacturing needs. Our manufacturing collaborators may be unable to successfully increase the manufacturing capacity for any current or potential future product candidate in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities. If our manufacturing collaborators are unable to successfully scale the manufacture of any current or potential future product candidate in sufficient quality and quantity, the development, testing, clinical trials and commercialization of that product candidate may be delayed or infeasible and regulatory approval or commercial launch of any potential resulting product may be delayed or not obtained, which could significantly harm our business.

In order to conduct clinical trials for our lead product candidates or commercialize, we will need to manufacture large quantities of these product candidates. We may continue to and currently expect to use third parties for our manufacturing needs. Our manufacturing collaborators may be unable to successfully increase the manufacturing capacity for any current or potential future product candidate in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities. If our manufacturing collaborators are unable to successfully scale the manufacture of any current or potential future product candidate in sufficient quality and quantity, the development, testing, clinical trials and commercialization of that product candidate may be delayed or infeasible and regulatory approval or commercial launch of any potential resulting product may be delayed or not obtained, which could significantly harm our business.

Previous wording

Our understanding of the number of people who suffer from certain types of moderate to severe IBD, sAH and retinal vascular associated diseases that SZN-043 and SZN-413, respectively, may be able to treat are based on estimates. These estimates may prove to be incorrect, and new studies may reduce the estimated incidence or prevalence of these diseases. The number of patients in the United States or elsewhere may turn out to be lower than expected, may not be otherwise amenable to treatment with our current or potential future product candidates or patients may become increasingly difficult to identify and access, all of which would adversely affect our business prospects and financial condition. In particular, the treatable population for our candidates may further be reduced if its estimates of addressable populations are erroneous or sub-populations of patients do not derive benefit from SZN-043 or SZN-413.

The key competitive factors affecting the success of our product candidates, if approved, are likely to be their efficacy, safety, convenience and price, the level of competition and the availability of coverage and adequate reimbursement from third-party payors. If any of our product candidates are approved and commercialized, it is likely that we will face increased competition as a result of other companies pursuing development of products to address similar diseases. For SZN-043 and our earlier stage research programs, we face competition from approved therapies and potential competition from product candidates in development for the indications we are pursuing or may pursue.

Our NOLs could expire unused and be unavailable to offset future income tax liabilities because of their limited duration or because of restrictions under U.S. tax law. NOLs generated in taxable years beginning before January 1, 2018 are permitted to be carried forward for only 20 taxable years under applicable U.S. federal income tax law. Under current law, NOLs arising in tax years beginning after December 31, 2020 may not be carried back. Moreover, under current law, NOLs generated in taxable years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such NOLs generally will be limited in taxable years beginning after December 31, 2020 to 80% of current year taxable income. As of December 31, 2023, we had NOLs of approximately $155.7 million and $53.0 million available to reduce future taxable income, if any, for federal and California state income tax purposes, respectively. NOLs generated after 2018 for federal tax reporting purposes of $143.2 million have an indefinite carryforward period. The remaining federal and all state NOLs begin expiring in 2036.

In general, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an “ownership change” (as defined under Section 382 of the Code and applicable Treasury Regulations) is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income. A Section 382 “ownership change” generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. We have determined that we likely had an ownership change in September 2020. As a result of the annual limitations caused by the ownership changes, it was estimated that approximately $1.3 million of federal tax credit and $27.4 million of California NOL will expire unutilized for income tax purposes, and such amounts are excluded from the carryforward balances of December 31, 2023. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, and some of which are outside our control. Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to reduce future income tax liabilities, including for state tax purposes. For these reasons, we may not be able to utilize a material portion of the NOLs reflected on our balance sheet, even if we attain profitability, which may result in increased future tax liability to us and could adversely affect our operating results and financial condition.

As we conduct preclinical studies and clinical trials of SZN-043, SZN-413 and other potential future product candidates, we are and will be exposed to significant product liability risks inherent in the development, testing, manufacturing and marketing of these product candidates. Product liability claims could delay or prevent completion of development programs. If we succeed in marketing products, such claims could result in an FDA investigation of the safety and effectiveness of our products, manufacturing processes and facilities or marketing programs and potentially a recall of products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we or any current or future collaborators may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material and adverse effect on our business, financial condition, results of operations and prospects.

Our product candidate SZN-043 has begun clinical development and its risk of failure is high. It is impossible to predict when or if our candidates or any potential future product candidates will prove effective in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical studies and then conduct extensive clinical trials to demonstrate the safety, purity, and potency, or efficacy of that product candidate in humans. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain, particularly in light of recent observations relating to clinical trial for SZN-043. Failure can occur at any time during the development process. The results of preclinical studies and clinical trials of any of our current or potential future product candidates may not be predictive of the results of later-stage clinical trials. 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. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials. We initiated first-in-human trials of SZN-043 in the second quarter of 2022. We have experienced (as described above), and may further experience, delays in initiating our planned clinical studies. We do not know whether planned clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin on time, need to be redesigned, will enroll patients on time or be completed on schedule, if at all.

There have been legal and political challenges to certain aspects of the ACA. For example, on June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. In addition, on August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is unclear how any additional future challenges or the healthcare reform measures of the Biden administration will impact the ACA and our business. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011 among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and will remain in effect through 2032, unless additional Congressional action is taken. The American Taxpayer Relief Act of 2012 among other things, reduced Medicare payments to several providers, including hospitals and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is unclear how any additional future challenges or the healthcare reform measures of the second Trump administration will impact the ACA and our business. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and, due to subsequent legislative amendments to the statute, including the Infrastructure Investment and Jobs Act, will remain in effect until 2032 unless additional Congressional action is taken.

Previous wording

On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers. Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. In addition, the IRA, among other things, (i) directs the U.S. Department of Health and Human Services, or HHS, to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 2023. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the Medicare drug pricing negotiation program is currently subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the Center for Medicare and Medicaid Innovation which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework. It is unclear whether this executive order or similar policy initiatives will be implemented in the future.

In addition, the IRA, among other things, (i) directs the U.S. Department of Health and Human Services, or HHS, to negotiate the price of certain high-expenditure, single-source biologics that have been on the market for at least 11 years covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, or the Medicare Drug Price Negotiation Program, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions took effect progressively starting in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon prices of the first ten drugs that were subject to price negotiations, although the Medicare Drug Price Negotiation Program is currently subject to legal challenges. On January 17, 2025, HHS selected fifteen additional products covered under Part D for price negotiation in 2025. Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price Negotiation Program. Further, on December 7, 2023, an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act was announced.
