In addition, our collaborators may have additional termination rights for convenience with respect to the collaboration as a whole or a particular program under the collaboration, under certain circumstances. For example, in August 2024, we announced that Regeneron had opted out of further co-development and co-commercialization of mivelsiran for portfolio prioritization reasons. As a result of Regeneron’s opt-out, we have full development and commercialization rights to mivelsiran in all indications but we will be responsible for funding further development and commercialization of mivelsiran, including the ongoing Phase 2 development program, without funding from Regeneron. Regeneron will be eligible to receive low double-digit royalties on sales of mivelsiran, if approved.

Our collaboration agreement with Roche requires that Roche pay us a milestone payment at the initiation of a Phase 3 clinical trial of zilebesiran. In the event that Roche determines to terminate our collaboration prior to the initiation of a Phase 3 clinical trial of zilebesiran, whether because of data from the earlier clinical development of zilebesiran or for any other reason, we would not receive the Phase 3 milestone from Roche, which could have a material adverse effect on our operating results and financial condition and make it more difficult for us to achieve profitability in 2025. In these circumstances, we would also need to determine whether to continue the clinical development of zilebesiran in the absence of funding and other support from Roche.

Additionally, in January 2024, the U.S. House of Representatives introduced the BIOSECURE ACT (H.R. 7085), which was subsequently amended on May 15, 2024 and passed by the U.S. House of Representatives on September 9, 2024, and the Senate advanced a substantially similar bill (S.3558), both of which would prohibit U.S. federal executive agencies from contracting with any entity where the biotechnology equipment or services of a “biotechnology company of concern” would be used in the performance of that contract. Generally, a “biotechnology company of concern” is a biotechnology company that is subject to the jurisdiction, direction, control, or operates on behalf of a foreign adversary’s government and poses a risk to the national security of the U.S. The final language, pathway and timing for either of these bills or their provisions to become law remain uncertain and, although the bill was passed in the House on September 9, 2024, the Senate did not pass the bill before the end of the 118th Congress’s term. Nonetheless, if these bills are re-introduced in the House and Senate and become law, or similar laws are passed, they would have the potential to severely restrict our ability to purchase services or products from, or otherwise collaborate with, certain Chinese “biotechnology companies of concern” without losing the ability to contract with, or otherwise receive reimbursement from, the U.S. government. We do business with companies in China and it is possible some of our contractual counterparties could be impacted by the legislation described above and alternative arrangements may need to be made.

The new administration has substantially altered prior U.S. government international trade policy and has commenced activities to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries. In addition, the new administration has initiated or is considering imposing tariffs on certain foreign goods. Related to this action, certain foreign governments, including China, have instituted or are considering imposing tariffs on certain U.S. goods. It remains unclear what the new administration or foreign governments will or will not do with respect to tariffs or other international trade agreements and policies. A trade war or other governmental action related to tariffs or international trade agreements or policies has the potential to disrupt our research activities, affect our suppliers, increase the cost of materials purchased to manufacture our products, impact our ability to sell our products outside the U.S. or to sell our products outside the U.S. at competitive prices and/or to affect the U.S. or global economy or certain sectors thereof and, thus, could adversely impact our business.

Current report

If the third parties we engage to supply materials or manufacture product candidates or products for preclinical testing or clinical or commercial supply should cease to do so for any reason, we would likely experience delays in advancing these preclinical tests and clinical trials and/or interruptions in commercial supply while we identify and qualify replacement suppliers or manufacturers, and we may be unable to obtain replacement supplies on terms that are favorable to us, or at all. If we are not able to obtain adequate supplies of our product candidates or products or the substances used to manufacture them, it could materially and adversely impact our business, prospects, operating results or financial condition.

Cybersecurity requires ongoing investment and diligence against evolving threats and is subject to federal and state regulation relating to the protection of confidential information. We may be required to expend significant additional resources to modify our protective measures, to investigate and remediate vulnerabilities or other exposures, to make required notifications, to restore our systems and fully recover from a cyber-attack, or to update our technologies and digital properties to comply with industry and regulatory standards, but we may not have adequate personnel, financial or other resources to fully meet these threats and evolving standards. We will also be required to effectively and efficiently govern, manage and ensure timely enhancements to our systems, including in their design, architecture and interconnections as well as their organizational and technical protections.

Current report

Our business depends upon the successful development and commercialization of our product candidates. These product candidates are in various stages of development and must satisfy rigorous standards of safety and efficacy before they can be approved for sale by the FDA or foreign regulatory authorities. Nonclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete, is uncertain as to outcome, and the historical failure rate for product candidates is high. It is impossible to predict when or if any of our product candidates will prove effective and safe in humans or will receive regulatory approval. Failure to advance our product candidates through clinical development could impair our ability to ultimately commercialize products, which could materially harm our business and long-term prospects.

Current report

In addition, from time to time, we report interim, topline, and preliminary data from our clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change. Interim or preliminary data from a clinical trial may not be predictive of final results from the clinical trial and are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment and treatment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data are available. If the interim, topline, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Clinical trials must be conducted in accordance with the legal requirements, regulations or guidelines of the FDA and corresponding regulatory authorities outside the United States. We could encounter delays if a clinical trial is suspended or terminated by us, by the FDA or any other regulatory authority, or if the IRBs of the institutions in which such trials are being conducted suspend or terminate the participation of their clinical investigators and sites subject to their review. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

If any of our current or future products or product candidates causes undesirable side effects or has other unexpected adverse properties, such side effects or properties could delay or prevent regulatory approval, limit the commercial potential or result in significant negative consequences following any potential marketing approval.

Current report

Although our RNAi therapeutics have been generally well-tolerated in our clinical trials to date, new safety findings may emerge. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. There can be no assurance that our product candidates will not cause undesirable side effects. If any product candidates we develop are associated with unacceptable side effects or deaths, we may need to abandon the development of such product candidates or limit development to certain uses or subpopulations in which the unacceptable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective, any of which would have a material adverse effect on our business, financial condition, results of operations and prospects. Furthermore, the occurrence of such adverse events could result in the suspension or termination of clinical trials of a product candidate by us, our collaborators, IRBs or ethics committees, or the FDA or a foreign regulatory authority, and may negatively impact the clinical and/or regulatory timelines of the impacted product candidates. For example, our Phase 1 clinical trial of mivelsiran for Alzheimer’s Disease remains on partial clinical hold in the United States due to findings observed in non-clinical chronic toxicology studies. While our clinical development of mivelsiran has not been impacted by the partial clinical hold because of the dose levels at which it applies, it is possible that the partial clinical hold could have an impact if our development plans change or that future partial or full clinical holds on mivelsiran or our other product candidates could impact our ability to advance the clinical development of such product candidate on our expected timelines or at all.

Current report

Inadequate funding for the FDA and other government agencies and/or potentially shifting priorities under the new administration could hinder the FDA’s and/or those other government agencies’ ability to hire and retain key leadership and other personnel, prevent new products and services from being developed and/or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business. The ability of the FDA to review and approve new products, to provide feedback on clinical trials and development programs, to meet with sponsors and to otherwise review regulatory submissions can be affected by a variety of factors, including government budget and funding levels; the ability to hire and retain key personnel and accept the payment of user fees; and statutory, regulatory, and policy changes, among other factors. Average review times at the agency may fluctuate as a result. Delays at the FDA as a result of these or other factors could impact the FDA’s ability to act on our sNDA submission for vutrisiran by the PDUFA target action date of March 23, 2025, or our other regulatory submissions, including our collaborator Sanofi’s NDA for fitusiran. In addition, government funding of other government agencies or of government programs that provide research funding on which our operations may rely directly or indirectly via third party research and development projects associated with our product development programs, is subject to the political process, which is inherently fluid and unpredictable. The failure for such funding to be furnished or to be furnished in a timely manner could impact our ongoing research and development initiatives.

Current report

Any disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies or to otherwise respond to regulatory submissions which would adversely affect our business. For example, the new administration has discussed several changes to the reach and oversight of the FDA, which could affect its relationship with the pharmaceutical industry, transparency in decision making and ultimately the cost and availability of prescription drugs. Additionally, over the last several years, the U.S. government has shut down multiple times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA and other government employees and stop critical activities. For example, the new administration recently announced plans to reduce the number of federal employees by establishing voluntary termination programs, by position eliminations or by involuntary terminations. If funding for the FDA is reduced, if the FDA workforce is reduced, if FDA priorities are changed or if a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, including our pending sNDA submission for vutrisiran and our collaborator Sanofi’s pending NDA for fitusiran, which could have a material adverse effect on our business.

Current report

We may seek a Fast Track, Priority Review, or Breakthrough Therapy designation or similar designations outside the U.S. for some of our product candidates. Product candidates that receive one or more of these designations may be eligible for, among other things, a priority regulatory review. Each of these designations is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for Fast Track, Priority Review, and/or Breakthrough Therapy designation, the FDA or similar regulatory authorities may disagree and instead determine not to make such designation. The receipt of one or more of these designations for a product candidate does not guarantee a faster development process, review or approval compared to products developed or considered for approval under conventional assessment procedures and does not assure ultimate approval by the FDA or similar regulatory authorities. In addition, even if one or more of our products or product candidates qualifies for Fast Track, Priority Review, and/or Breakthrough Therapy designation, the FDA or similar regulatory authorities may later decide to withdraw such designation if it determines that the product or product candidate no longer meets the conditions for qualification.

Current report

Furthermore, even if we or our collaborators receive approval of an NDA or foreign marketing application for a product candidate, the FDA or the applicable foreign regulatory agency may grant approval or other marketing authorization contingent on the performance of costly additional clinical trials, including post-market clinical trials. The FDA or the applicable foreign regulatory agency also may approve or authorize for marketing a product candidate for a more limited indication or patient population than we originally request, and the FDA or applicable foreign regulatory agency may not approve or authorize the labeling that we believe is necessary or desirable for the successful commercialization of a product candidate. Any of these restrictions or commitment could limit an approved product’s market opportunity and have a negative impact on our business, prospects, operating results and financial condition and our stock price. For example, if the FDA or foreign regulatory agency approves the sNDA for vutrisiran for the treatment of ATTR amyloidosis with cardiomyopathy with a more limited label than we are seeking, it could limit the scope of the commercial opportunity for vutrisiran.

Current report

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our approved products and any product candidates we may develop and adversely affect our business, financial condition, results of operations and prospects.

Current report

The U.S. Supreme Court’s June 2024 decision in Loper Bright Enterprises v. Raimondo overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. The Loper decision could result in additional legal challenges to regulations and guidance issued by federal agencies, including the FDA, on which we rely. Any such legal challenges, if successful, could have a material impact on our business. Additionally, the Loper decision may result in increased regulatory uncertainty, inconsistent judicial interpretations, and other impacts to the agency rule-making process, any of which could adversely impact our business and operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action or as a result of legal challenges, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, our business could be materially harmed.

Current report

The FDA and other regulatory agencies closely regulate the post-approval marketing and promotion of products to ensure that they are marketed only for the approved indications and in accordance with the provisions of the approved labeling. Although physicians are generally permitted, based on their medical judgment, to prescribe products for indications other than those approved by the applicable regulatory agency, manufacturers are prohibited from promoting their products for such off-label uses. For example, we may not currently promote ONPATTRO or AMVUTTRA in the U.S. for use in any indications other than the treatment of hATTR amyloidosis with polyneuropathy in adults. If a regulatory agency determines that our promotional materials, or other activities constitute off-label promotion, it could request that we modify our promotional materials or other activities, conduct corrective advertising, or subject us to regulatory enforcement actions, such as the issuance of a warning or untitled letter, injunction, seizure, civil fines and criminal penalties. It also is possible that other federal, state, or foreign enforcement authorities might take action if they believe that the alleged improper promotion led to the submission and payment of claims for an off-label use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. Even if it is later determined we were not in violation of these laws, we may be faced with negative publicity, incur significant expenses defending our actions, and have to divert significant management resources from other matters.

Current report

Furthermore, the new administration has indicated that lowering prescription drug prices is a priority, but the nature and impact of any potential policy changes remain uncertain. While frameworks like the IRA aim to control costs, their implementation under the new administration could introduce further regulatory changes, such as additional price restrictions on products we sell to Medicare or other government purchasers. Any such developments could adversely affect reimbursement, competitive dynamics, and our business. We continue to monitor legislative reforms and assess their potential impact on our operations, but we cannot predict their ultimate effect on our business. Additionally, the new administration may propose policy changes that create additional uncertainty for our business. These may include new price restrictions on products we sell to Medicare or other government purchasers, or other regulatory changes impacting reimbursement or competitive dynamics in multisource markets.

•The California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020, or, collectively, the CCPA, that, among other provisions, gives California residents rights to their personal information and imposes various privacy and security obligations on regulated businesses. Furthermore, comprehensive privacy laws similar to the CCPA and consumer health data laws have been enacted in more than twelve other states and proposed in nearly one third of all states. Washington’s law regulating consumer health data contains a private right of action. The effects of the CCPA and other state privacy laws, and the creation of new regulatory bodies, such as the California Privacy Protection Agency, increases the cost and complexity of operating our business and our exposure to regulatory investigations, enforcement, fines, and penalties, any of which could negatively impact our business and operations. Failure to comply with these obligations could result in damage to our reputation and legal liability, censures, penalties and fines, disgorgement of profits, restitution to customers, remediation, the issuance of cease-and-desist orders, or injunctive or other equitable relief against us, which individually or in the aggregate could negatively impact our financial results. Depending on the nature of the violation, we may be required to offer restitution or remediation to customers, and the cost of doing so could exceed our loss reserves.

Increasingly, states are enacting legislation requiring manufacturers to report drug pricing information. However, states have not always clearly defined their reporting requirements, resulting in manufacturers failing to properly disclose the required pricing information.

On July 12, 2024, Acuitas Therapeutics Inc., or Acuitas, filed a declaratory judgment action against us in the U.S. District Court for the District of Delaware, seeking a judgment adding certain Acuitas employees as co-inventors on the patents we have asserted against Pfizer/BioNTech and Moderna in our lawsuits described below. On September 19, 2024, we filed a motion to dismiss arguing that Acuitas did not have standing to sue and failed to state a claim upon which relief could be granted. The court has not yet ruled on our motion.

Geopolitical risks associated with the ongoing military conflict between Russia and Ukraine could have an adverse impact on our business, prospects, operating results and financial condition, including our clinical trials.

Previous report

Russia’s invasion of Ukraine, and the global response, including the imposition of sanctions by the U.S., EU and other countries, has resulted in global business disruptions and economic volatility and may have an adverse impact on our business, including our clinical trials. The uncertain nature, magnitude, and duration of hostilities stemming from the conflict in Ukraine, including the potential effects of sanctions retaliatory cyber-attacks on the world economy and markets, have contributed to increased market volatility and uncertainty, which could continue to have an adverse impact on macroeconomic factors that might affect our business and operations.

Previous report

Additionally, the ongoing conflict in Ukraine has disrupted the ability of certain of our contract research organizations, or CROs, to conduct clinical trials at certain sites in Ukraine. We cannot be certain what the overall impact of this conflict will be on our ability to conduct and complete our clinical trials on schedule. However, interruptions of our clinical trials could significantly delay our clinical development plans and potential authorization or approval of our product candidates, which could increase our costs and jeopardize our ability to successfully commercialize our product candidates.

Health regulatory agencies globally may also experience disruptions in their operations as a result of the COVID-19 pandemic or future public health emergencies, which could impact review, inspection and approval timelines. Since March 2020, when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been working to resume pre-pandemic levels of inspection activities, including routine surveillance, bioresearch monitoring and pre-approval inspections. Should the FDA determine that an inspection is necessary for approval of a marketing application and an inspection cannot be completed during the review cycle due to restrictions on travel, and the agency does not determine a remote interactive evaluation to be adequate, the FDA has stated that it generally intends to issue, depending on the circumstances, a complete response letter or defer action on the application until an inspection can be completed.

Before conducting clinical trials to demonstrate the safety and efficacy of our product candidates in humans in support of IND applications or similar applications in other jurisdictions, we must complete pre-clinical studies, which includes animal studies. In addition, we rely on third-party service providers to source certain materials for such pre-clinical studies. Our ability to complete our pre-clinical studies is contingent on, among other things, our ability to source animals and other supplies required for the conduct of such studies. If we are unable to obtain such supplies, we may be unable to complete such pre-clinical studies in a timely manner or at all. For example, some of our IND-enabling toxicology and other studies require certain non-human primates that have customarily been imported from the People’s Republic of China and Cambodia, and the supply of these non-human primates was constrained in 2022 due to various factors. If we were to encounter delays in obtaining a sufficient supply of such non-human primates to enable the conduct of our pre-clinical studies, our ability to complete pre-clinical studies could be impaired and our submission of IND applications and similar applications in other jurisdictions could be delayed, which would have an adverse impact on the development timelines of the impacted product candidates.

Previous report

Before obtaining regulatory approval for the commercial distribution of our product candidates, we must conduct, at our own expense, extensive nonclinical tests and clinical trials to demonstrate the safety and/or efficacy in humans of our product candidates. Nonclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome, and the historical failure rate for product candidates is high. We currently have multiple programs in clinical development, including internal and collaborated programs in Phase 3 development, as well as several earlier-stage clinical programs. However, we may not be able to further advance any of our product candidates through clinical trials and regulatory approval.

Previous report

In addition, we, the FDA or other applicable regulatory authorities, or an institutional review board, or IRB, or similar foreign review board or committee, may delay initiation of or suspend clinical trials of a product candidate at any time for various reasons, including if we or they believe the healthy volunteer subjects or patients participating in such trials are being exposed to unacceptable health risks. Among other reasons, adverse side effects of a product candidate or related product on healthy volunteer subjects or patients in a clinical trial could result in our decision, or a decision by the FDA or foreign regulatory authority, to suspend or terminate the clinical trial, or, in the case of regulatory agencies, a refusal to approve a particular product candidate for any or all indications of use.

Previous report

Although our RNAi therapeutics have been generally well-tolerated in our clinical trials to date, new safety findings may emerge. The occurrence of serious adverse events, or SAEs, and/or adverse events, or AEs, can result in the suspension or termination of clinical trials of a product candidate by us, our collaborators, or the FDA or a foreign regulatory authority, and may negatively impact the clinical and/or regulatory timelines of the impacted product candidates. For example, in October 2016, we discontinued our revusiran program and in September 2017, we announced that we had temporarily suspended dosing in all ongoing fitusiran studies pending further review of a fatal thrombotic SAE that occurred in a patient who was receiving fitusiran in our Phase 2 OLE study. More recently, in October 2020, Sanofi voluntarily paused dosing in all ongoing fitusiran clinical studies to assess reports of non-fatal thrombotic events in patients participating in the ATLAS Phase 3 program. Following an assessment of available data and alignment with regulators, patients restarted on fitusiran under amended protocols in ongoing clinical studies and, in October 2021, Sanofi announced that a potential filing date for fitusiran had been moved to 2024 due to the introduction of a revised dosing regimen in the ongoing phase 3 studies. In addition, the occurrence of SAEs and/or AEs could also result in refusal by the FDA or a foreign regulatory authority to approve a particular product candidate for any or all indications of use, or in limitations in the label of any approved product.

Clinical trials also require the review, oversight and approval of IRBs, or, outside of the U.S., independent ethics committees, which continually review clinical investigations and protect the rights and welfare of human subjects. Inability to obtain or delay in obtaining IRB or ethics committee approval can prevent or delay the initiation and completion of clinical trials, and the FDA or foreign regulatory authorities may decide not to consider any data or information derived from a clinical trial not subject to initial and continuing IRB or ethics committee review and approval, as the case may be, in support of a marketing application.

The FDA has significant post-market authority, including, for example, the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate serious safety risks related to the use of a product and to require withdrawal of the product from the market. The FDA also has the authority to require a REMS plan after approval, which may impose further requirements or restrictions on the distribution or use of an approved product. As our approved products are used commercially, we or others could identify previously unknown side effects or known side effects could be observed as being more frequent or severe than in clinical studies or earlier post-marketing periods, in which case:

Physicians have the discretion to prescribe approved drug products for uses that are not described in the product’s labeling and that differ from those approved by the FDA or other applicable regulatory agencies. Off-label uses are common across medical specialties. Although the FDA and other regulatory agencies that approve drug products do not regulate a physician’s practice of medicine or choice of treatments, the FDA and other regulatory agencies regulate a manufacturer’s communications regarding off-label use and prohibit off-label promotion, as well as the dissemination of false or misleading labeling or promotional materials, including by their agents. Manufacturers and their agents may not promote drugs for off-label uses or provide information in the promotion of drug products that is not consistent with the approved labeling for those products. For example, we may not currently promote ONPATTRO or AMVUTTRA in the U.S. for use in any indications other than the treatment of hATTR amyloidosis with polyneuropathy in adults. The FDA and other regulatory and enforcement authorities actively enforce laws and regulations prohibiting promotion of off-label uses and the promotion of products for which marketing approval has not been obtained, and if in the future we are found to have improperly marketed or promoted any of our commercial products, we may be subject to a broad range of civil, administrative and criminal penalties, including injunctive relief related to such commercial products’ promotional activities, substantial fines or penalties, and other legal or equitable sanctions. Any adverse decision, finding, allegation, or exercise of enforcement or regulatory discretion could harm our business, prospects, operating results, and financial condition. Other internal or government investigations or legal or regulatory proceedings, including lawsuits brought by private litigants, may also follow as a consequence.

Previous report

Notwithstanding regulations related to product promotion, the FDA and other regulatory authorities allow companies to engage in truthful, non-misleading and non-promotional scientific exchange concerning their products, and we intend to engage in medical education activities and communicate with healthcare providers in compliance with all applicable laws and regulatory guidance. Nonetheless, the FDA, other applicable regulatory authorities, competitors, and other third parties may take the position that we are not in compliance with such regulations, and if such non-compliance is proven, it could harm our reputation or divert financial and management resources from our core business, and would have a material adverse effect on our business, prospects, operating results or financial condition. Moreover, any threatened or actual government enforcement actions or lawsuits by third parties could also generate adverse publicity, which could decrease demand for our products and require that we devote substantial resources that otherwise could be used productively on other aspects of our business.

Previous report

In addition to our medical education efforts, we also offer patient support services to assist patients receiving treatment with our commercially approved products. Manufacturers have increasingly become the focus of government investigation of patient support programs based on allegations that through such services illegal inducements are provided to physicians and/or patients, leading to improper utilization of government resources through Medicare, Medicaid and other government programs. Companies that are found to have violated laws such as the federal Anti-Kickback Statute and/or the federal False Claims Act, or FCA, face significant liability, including civil and administrative penalties, criminal sanctions, and potential exclusion from participation in government programs.

Furthermore, the Biden administration has indicated that lowering prescription drug prices is a priority, but we do not know the impact of policies established by the Biden administration to lower the prices of prescription drug prices. For example, the Center for Medicare and Medicaid Innovation is developing new models intended to lower drug costs under Medicare and Medicaid, including designing new payment methods for drugs approved via FDA’s accelerated approval pathway, creating a list of generic drugs for which the out-of-pocket Part D costs will be capped at $2 a month per drug, and establishing new approach for administering outcomes-based agreements for cell and gene therapies. We do not know what additional steps the Biden administration may take to attempt to lower prescription drug prices or the impact of such steps. Although a number of these and other proposed measures may require authorization through additional legislation to become effective, and the current U.S. presidential administration may reverse or otherwise change these measures, both the current U.S. presidential administration and Congress have indicated that they will continue to seek new measures to control drug costs.

Three states have additionally enacted laws regulating “consumer health data,” which impose additional obligations on regulated entities beyond state comprehensive privacy laws, such as to obtain distinct consents for certain collection and sharing of consumer health data, obtain authorization to sell consumer health data, and maintain a consumer health data privacy policy. Washington’s law regulating consumer health data contains a private right of action. The effects of the CCPA and other state privacy laws are potentially significant and may require us to modify our data collection or processing practices and policies and to incur substantial costs and expenses in an effort to comply and increase our potential exposure to regulatory enforcement and/or litigation.

Some state laws also require pharmaceutical manufacturers to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, in addition to requiring manufacturers to report information related to payments to physicians and other healthcare providers or marketing expenditures and pricing information. State and foreign laws also govern the privacy and security of health information, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating our compliance efforts.

Third party patient assistance programs that receive financial support from companies have become the subject of enhanced government and regulatory scrutiny. The OIG has established guidelines that suggest that it is lawful for pharmaceutical manufacturers to make donations to charitable organizations who provide co-pay assistance to Medicare patients, provided that such organizations, among other things, are bona fide charities, are entirely independent of and not controlled by the manufacturer, provide aid to applicants on a first-come basis according to consistent financial criteria and do not link aid to use of a donor’s product. However, donations to patient assistance programs have received negative publicity and have been the subject of multiple government enforcement actions, related to allegations regarding their use to promote branded pharmaceutical products over other less costly alternatives. Specifically, in recent years, there have been multiple settlements resulting from government claims challenging the legality of patient assistance programs under a variety of federal and state laws. We have made and may continue to make grants to independent charitable foundations that help financially needy patients with their premium, co-pay, and co-insurance obligations. If we do so, and if we or our donation recipients are deemed to be acting in violation of relevant laws, regulations or evolving government guidance, we could be subject to damages, fines, penalties, or other criminal, civil, or administrative sanctions or enforcement actions.

Third parties may sue us for infringing their patent rights. For example, in October 2017 Silence sued us in the UK alleging that ONPATTRO and other investigational RNAi therapeutics we or MDCO were developing infringed one or more Silence patents. In December 2018 we and Silence settled all ongoing litigation between us. A third party may also claim that we have improperly obtained or used its confidential or proprietary information.

In August 2020, the Financial Accounting Standards Board published an Accounting Standards Update, which we refer to as ASU 2020-06, which simplified certain of the accounting standards that apply to convertible notes. ASU 2020-06 became effective for us beginning January 1, 2022.

Our dependence on collaborators for capabilities and funding means that our business could be adversely affected if any collaborator materially amends or terminates its collaboration agreement with us, in whole or in part, or fails to perform its obligations under that agreement. Our current or future collaborations, if any, may not be scientifically or commercially successful. Disputes may arise in the future with respect to the ownership of rights to technology or products developed with our collaborators, which could have an adverse effect on our ability to develop and commercialize any affected product candidate. Our current collaborations allow, and we expect that any future collaborations will allow, either party to terminate the collaboration for a material breach by the other party.

Clinical trials of a new product candidate require the enrollment of a sufficient number of patients, including patients who are suffering from the disease the product candidate is intended to treat and who meet other eligibility criteria. Our ability to enroll patients in our clinical trials in sufficient numbers and on a timely basis is subject to a number of factors. Clinical trials are expensive and require significant operational resources. Delays in patient enrollment or unforeseen drop-out rates may result in increased costs and longer development times.

Because there may be approved treatments for some of the diseases for which we or our collaborators may seek approval, including vutrisiran for the treatment of ATTR amyloidosis with cardiomyopathy, or treatments in development which will be approved by the time we or our collaborators file for approval, in order to receive regulatory approval, we or they may need to demonstrate through clinical trials that the product candidates we develop to treat these diseases are not only safe and effective, but safer and/or more effective than other products.

Current report — wording carried from elsewhere

The FDA or foreign regulatory authorities may request additional clinical or other data or information in connection with the regulatory review of our or our collaborators’ product candidates, including by issuing a complete response letter that may require that we or our collaborators submit additional clinical or other data or impose other conditions that must be met in order to secure final approval of our or our collaborators’ NDA applications, including potentially requiring a facility inspection. Even if such data and information are submitted, or any such inspection is completed, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval.

Current report — wording carried from elsewhere

Any delay or failure in obtaining required approvals for our product candidates or our collaborated product candidates could have a material adverse effect on our ability to generate revenues from any product candidate for which we or our collaborators may seek approval in the future. For example, as a result of the CRL from the FDA in response to our sNDA for patisiran as a treatment for ATTR amyloidosis with cardiomyopathy, our ability to generate product revenues for patisiran has been negatively impacted.

Our products are subject to continuing regulatory oversight following approval, including the review of adverse drug experiences and clinical results that are reported after our drug products are made commercially available. This includes results from any post-marketing tests or surveillance to monitor the safety and efficacy of our approved products or other products required as a condition of approval or otherwise agreed to by us. Products are more widely used by patients once approval has been obtained and therefore side effects and other problems may be observed after approval that were not seen or anticipated, or were not as prevalent or severe, during pre-approval clinical trials or nonclinical studies. The subsequent discovery of previously unknown or underestimated problems with a product could result in:

We believe that the efforts of governments and third-party payors to contain or reduce the cost of healthcare and legislative and regulatory proposals to broaden the availability of healthcare will continue to affect the business and financial condition of pharmaceutical and biopharmaceutical companies.

10, 2023, the EC announced that it had adopted its adequacy decision for that data privacy framework, labelled the EU-U.S. Data Privacy Framework. The adequacy decision concluded that the U.S. ensures an adequate level of protection for personal data transferred from the EU to US companies under the new framework, and the EC stated that as a result personal data can flow safely from the EU to US companies participating in the framework, without having to put in place additional data protection safeguards. The EU-U.S. Data Privacy Framework is subject to periodic reviews, to be conducted by the EC, together with other European data protection authorities and U.S. authorities, with the first review to take place within a year of adoption of the adequacy decision. A case has been lodged with and remains pending before the EU courts challenging the validity of the EU-U.S. Data Privacy Framework.

We may need to resort to litigation to enforce a patent issued or licensed to us or to determine the scope and validity of proprietary rights of others or protect our proprietary information and trade secrets. In March 2022, we announced that we separately filed suit in United States District Court for the District of Delaware against Pfizer and Moderna seeking damages for infringement of U.S. Patent No. 11,246,933, or the ’933 patent in the parties’ manufacture and sale of their messenger RNA, or mRNA, COVID-19 vaccines. Pfizer joined BioNTech SE, or BioNTech, to the suit and filed counterclaims. In July 2022, we filed an additional lawsuit in United States District Court for the District of Delaware against each of Pfizer/BioNTech and Moderna seeking damages for infringing U.S. Patent No. 11,382,979, or the ’979 patent. The court combined the two patents in a single suit for each of Pfizer/BioNTech, or the 2022 Lawsuit, and Moderna with trial dates set for each in November 2024. On May 26, 2023, we filed additional lawsuits against Pfizer and Moderna in Delaware seeking damages for infringing U.S. Patent

The two separate suits against Pfizer/BioNTech are ongoing and in September 2023, we and Pfizer/BioNTech agreed to consolidate the 2022 and 2023 lawsuits into one case, with a trial date set for July 7, 2025. The aforementioned patents relate to our biodegradable cationic lipids that are foundational to the success of the mRNA COVID-19 vaccines.

We may need to resort to litigation to enforce a patent issued or licensed to us or to determine the scope and validity of proprietary rights of others or protect our proprietary information and trade secrets. For example, during the second quarter of 2015, we filed a trade secret misappropriation lawsuit against Dicerna to protect our rights in the RNAi assets we purchased from Merck Sharp & Dohme Corp., or Merck. In April 2018, we and Dicerna settled all claims in the litigation between us. In

Quark, Sylentis and other companies under which these companies may independently develop RNAi therapeutics against a limited number of targets. Any one of these companies may develop its RNAi technology more rapidly and more effectively than we do. In addition, as a result of agreements that we have entered into, Takeda has obtained a non-exclusive license, and Arrowhead, as the assignee of Novartis, has obtained specific exclusive licenses for 30 gene targets, that include access to certain aspects of our technology.
