Current report
In clinical trials of volixibat, the most common AEs reported in the volixibat treatment group were mild to moderate gastrointestinal (“GI”) events (diarrhea, abdominal pain, nausea and vomiting) and vitamin D deficiency. In the interim analysis of the PBC VANTAGE study, the incidence of diarrhea in patients on volixibat was 77% with all cases mild to moderate; one patient discontinued the study due to an AE of diarrhea. In the VISTAS study in PSC patients, diarrhea was reported in 40% of patients in the volixibat treatment group through week 28 compared to 9% on placebo. In the volixbat treatment arm, 9% of patients discontinued the study due to AEs compared to 3% on placebo. By week 28, three patients discontinued the study in the volixibat treatment arm due to diarrhea and one patient discontinued the study due to alanine aminotransferase (“ALT”) increases. Patients in the volixibat treatment group experienced more frequent elevations in liver laboratory values of ALT, aspartate aminotransferase (“AST”), alkaline phosphatase (“ALP”), and bilirubin and more AEs related to liver laboratory values such as increased ALT levels, increased blood bilirubin levels and jaundice compared to patients in the placebo group.
Current report
In clinical studies of brelovitug, the most common treatment-related AEs were injection-related events that resolved within 1-2 days, and cases of flu-like illness that were mild-moderate in severity.

If generic manufacturers are successful in their use of litigation or regulatory means to obtain approval for generic versions of LIVMARLI, our revenue and results of operations would be adversely affected.
Current report
The Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Amendments of the Federal Food, Drug, and Cosmetic Act (the “Hatch-Waxman Act”), permits the FDA to approve ANDAs for generic versions of branded drugs. We refer to this process as the ANDA process. The ANDA process permits competitor companies to obtain marketing approval for a drug with the same active ingredient as a branded drug, but does not generally require the conduct and submission of clinical efficacy studies for the generic product. In place of such clinical studies, an ANDA applicant usually needs only to submit data demonstrating that its product is bioequivalent to the branded product.
Current report
Pursuant to the Hatch-Waxman Act, companies were permitted to file ANDA applications for proposed generic versions of LIVMARLI on or after September 29, 2025. We own, license or have acquired several patents that cover LIVMARLI, and we have listed those patents in conjunction with that product in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”). The Hatch-Waxman Act requires an ANDA applicant seeking FDA approval of its proposed generic product prior to the expiration of our Orange Book-listed patents to certify to the FDA, for all patents listed in the Orange Book for LIVMARLI, that (a) the applicant is not seeking approval until after the expiration date of the patent, or (b) the applicant believes the patent is invalid or will not be infringed by the manufacture, use or sale of the drug for which the application has been submitted (a paragraph IV certification) and notify us of such certification (a paragraph IV notice). For a method-of-treatment patent listed in the Orange Book, the applicant may also choose to submit a section viii statement certifying that its proposed product label does not contain any language regarding the patented method-of-use instead of certifying to the patent. Upon receipt of a paragraph IV notice, the Hatch-Waxman Act allows us, with proper basis, to bring an action for patent infringement against the ANDA filer, asking that the proposed generic product not be approved until after our patents expire. If we commence a lawsuit within 45 days from receipt of the paragraph IV notice, the FDA cannot finally approve the generic’s ANDA until the earlier of 30 months (known as the “30-month stay”), the expiration of the patent, settlement of the lawsuit, or a decision in the litigation resolving it in favor of the ANDA applicant. The discovery, trial and appeals process in such a lawsuit is costly, time consuming, and may result in generic competition if the ANDA applicant prevails.
Current report
On December 19, 2025, we, along with Satiogen Pharmaceuticals, Inc. and Shire Human Genetic Therapies, Inc. as co-plaintiffs, filed four complaints against Sandoz Inc. (“Sandoz”); Annora Pharma Private Limited, Hetero Labs Limited, and Hetero USA Inc. (together, “Hetero”); Zenara Pharma Private Limited and Biophore India Pharmaceuticals Private Limited (together, “Biophore”); and Zydus Lifesciences Global FZE, Zydus Lifesciences Limited, and Zydus
Current report
Pharmaceuticals (USA) Inc. (together, “Zydus”) (all collectively, “Defendants”) in the U.S. District Court for the District of Delaware (the “LIVMARLI Patent Litigations”), alleging infringement of certain Orange Book listed patents covering LIVMARLI (the “LIVMARLI Patents”). The LIVMARLI Patent Litigations were initiated, in accordance with the procedures set out in the Hatch-Waxman Act, following the submission by Defendants of ANDAs directed to generic versions of LIVMARLI. Defendants’ ANDAs seek approval to market generic versions of LIVMARLI prior to the expiration of one or more of the LIVMARLI Patents and allege that one or more of the LIVMARLI Patents are invalid, unenforceable, and/or not infringed. We are seeking, among other relief, an order that the effective date of any FDA approval of Defendants’ ANDAs be no earlier than the expiration of the asserted patents, and such further and other relief as the court may deem appropriate. Based on our initiating the litigation, a 30-month stay is in place through March 29, 2029, preventing Defendants from marketing generic versions of LIVMARLI® during that time, subject to the exceptions noted above. On February 20, 2026, Sandoz asserted counterclaims against us and our co-plaintiffs seeking declaratory judgments of non-infringement and invalidity with respect to certain LIVMARLI Patents. On March 30, 2026, Biophore asserted counterclaims against us and our co-plaintiffs seeking declaratory judgments of non-infringement and invalidity with respect to certain LIVMARLI Patents. We and our co-plaintiffs have denied all asserted declaratory judgment claims. On April 16, 2026, the Court ordered that the four pending cases against Sandoz, Hetero, Biophore and Zydus be consolidated for pretrial purposes. Trial in the LIVMARLI Patent Litigations has not yet been scheduled. We cannot make any predictions about the final outcome of these matters or the timing thereof.
Current report
Any approved ANDA or related legal proceeding could have an adverse impact on our stock price. Litigation both by us to enforce our patents and by others to invalidate our patents has, and is likely to continue to, cost a substantial amount and require significant management attention. If the validity and/or enforceability of our patents covering LIVMARLI are not upheld in litigation, or if any ANDA filer we bring suit against is found to not infringe our asserted patents, the resulting generic competition following the expiration of regulatory exclusivity would have a material adverse effect on our revenue and results of operations.
Current report
We may also face generic competition for LIVMARLI in certain non-U.S. countries, and there is a process somewhat similar to the ANDA process under Article 10 of Directive 2001/83/EC in the EU. Our ability to successfully market and sell LIVMARLI in many countries in which we operate is based upon patent rights or certain regulatory forms of exclusivity, or both. The scope of our patent rights and regulatory exclusivity for LIVMARLI vary from country to country and are dependent on the availability of meaningful legal remedies in each country. If our patent rights and regulatory exclusivity for LIVMARLI are successfully challenged, expire, or otherwise terminate in a particular country, the resulting generic competition could have a material adverse effect on our revenue and results of operations.
Current report
On December 11, 2025, the European Commission, the Parliament and the European Council reached a political agreement on a comprehensive overhaul of EU pharmaceutical legislation (the “Pharma Package”). The reform has been under negotiation since the European Commission submitted its proposal in April 2023. The Pharma Package, comprised of a new directive and regulation to replace existing legislation, aims to modernize the EU framework. The political agreement is still subject to formal approval by the European Parliament and Council. If approved in the form proposed, the Pharma Package will, among other changes, reduce the baseline market protection period by one year, with limited opportunities for extensions, capped at a maximum of eleven years; reshape the incentives regime for orphan medicinal products, by introducing “breakthrough” orphan medicinal products (those addressing diseases with no available medicinal treatment) which will benefit from 11 years of market exclusivity; and expand the “Bolar” exemption to permit generic and biosimilar manufacturers to conduct preparatory activities for regulatory submissions, including pricing and reimbursement, and participate in procurement tenders while patent protection remains in force. A decrease in market exclusivity opportunities for our product candidates in the EU, combined with the expanded Bolar exemption, could open them to generic or biosimilar competition earlier than under the current regime, potentially impacting reimbursement status and the commercial prospects of our product candidates.
Current report
There are currently no approved products available in the U.S. for the treatment of chronic HDV infection. Bulevirtide, which is commercialized by Gilead Sciences, is approved for commercial sale in the EU and Gilead is seeking approval from the FDA to commercialize bulevirtide in the U.S. In addition, we are aware that Vir Biotechnology is developing tobevibart in combination with elebsiran for the treatment of chronic HDV. We are aware of several other agents in clinical development for the treatment of chronic HDV including Gilead Science’s GS-4321, Shanghai HEP Pharmaceutical Co., Ltd.’s Hepalatide, Suzhou Ribo Life Science Co., Ltd.'s RBD1016, Assembly Biosciences’s ABI-6250, Huahui Health Ltd.’s Libevitug and HH-1270, Replicor Inc.’s REP 2139-Mg and REP 2139-Ca, and EIT Pharma’s Jitixib® (Lonafarnib).

Additionally, the U.S. Department of Justice issued a rule entitled the Preventing Access to U.S. Sensitive Personal Data and Government-Related Data by Countries of Concern or Covered Persons, which places additional restriction on certain data transactions involving countries of concern (e.g., China, Russia, Iran) and covered persons (i.e., individuals or entities who are designated as such by the U.S. Attorney General or considered “foreign persons” and are majority owned by, organized under the laws of, a primary resident in, or a contractor of, a covered person or country of concern, as applicable) that may impact certain business activities such as vendor engagements, sale or sharing of data, employment of certain individuals, and investor agreements. Violations of the rule could lead to significant civil and criminal fines and penalties. The rule applies regardless of whether data is anonymized, key-coded, pseudonymized, de-identified or encrypted, which presents particular challenges for companies like ours and may impact our ability to engage in certain transactions or agreements with certain third parties in the future.
Current report
The manufacturing of biologics involves complex, multi-step processes, including the use of living cells and biological materials that are inherently variable and difficult to control. Small changes in raw materials, equipment, process parameters, environmental conditions, or operator performance can result in material differences in product quality, yield, stability, or potency, including the risk of contamination or batch failure. As a result, biologic manufacturing processes may be more susceptible to interruptions, delays, and quality issues than the manufacture of small-molecule drugs. Moreover, scaling up biologic manufacturing from clinical to commercial quantities involves additional risks, including unanticipated process challenges, reduced yields, or the need for process changes that may require regulatory review or approval. Any such changes could delay commercialization, increase costs, or adversely impact product comparability or regulatory acceptance.

There have been amendments and executive, judicial and Congressional challenges to certain aspects of the Affordable Care Act. In addition, the Affordable Care Act has been subject to various health reform measures. On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was signed into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in Affordable Care Act 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 through a newly established manufacturer discount program. It is unclear how any additional health care reform measures of the current presidential administration will impact the Affordable Care Act and our business.
Previous report
Further, the IRA will, among other things, (i) allow HHS to negotiate the price of certain single-source drugs and biologics that have been on the market for at least 7 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” under the law (the “Medicare Drug Price Negotiation Program”) and (ii) impose rebates under Medicare Part B and 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. HHS has and will continue to issue and update guidance as these programs are implemented. These provisions took effect progressively starting in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon reimbursement prices for 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.

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.

Symptomatic treatment with antipruritics, such as cholestyramine, typically provides only modest relief. Bristol Myers Squibb Company has discontinued its brand name cholestyramine, but generic versions of the drug are marketed by Upsher-Smith Laboratories, Inc., Par Pharmaceutical Companies, Inc., Sandoz Inc., the generic pharmaceuticals division of Novartis AG and others. UDCA, also known as ursodiol, is marketed by a number of generic pharmaceutical companies such as Mylan Inc., Actavis Inc., Lannett Company, Inc. and Par Pharmaceutical Companies, Inc.

Previous wording
A trend in the healthcare industry is cost containment. Third-party payors are developing increasingly sophisticated methods of controlling healthcare costs by, among other methods, limiting or preventing (for example via prior authorization, prior therapy or step edit requirements) coverage for particular medications, requiring drug companies to provide them with varying levels of discounts from list prices and/or challenging the value of list prices charged for medical products. Similarly, the containment of healthcare costs has become a priority for federal, national, and state governments around the world. Coverage decisions may depend upon the size of a patient population, perceptions of clinical efficacy and economic standards that may disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available.

Similarly, the containment of healthcare costs has become a priority for federal, national, and state governments around the world. For example, the U.S. Department of Health and Human Services (“HHS”) imposes rebates on many Medicare Part B and Medicare Part D products to penalize price increases that outpace inflation on an annual basis. HHS has also been empowered to negotiate the price of certain single-source drugs that have been on the market for at least seven (7) years covered under Medicare as part of the Medicare Drug Price Negotiation Program. Each year up to twenty (20) products will be selected by HHS for the Medicare Drug Price Negotiation Program. Products subject to the Medicare Drug Price Negotiation Program are expected to experience a significant reduction in reimbursement from the Medicare program on a per unit basis. If coverage and adequate reimbursement are not available, or are available only to limited levels, we may not be able to successfully commercialize our current and any future product candidates that we develop, which could have an adverse effect on our operating results and our overall financial condition. Coverage decisions may depend upon the size of a patient population, perceptions of clinical efficacy and economic standards that may disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available.
Previous wording
We expect that legislators, policymakers and healthcare insurance funds in the EU Member States will continue to propose and implement cost-containing measures, such as lower maximum prices, lower or lack of reimbursement coverage and incentives to use cheaper, usually generic, products as an alternative to branded products, and/or branded products available through parallel import to keep healthcare costs down. Moreover, in December 2021, Regulation No 2021/2282 on Health Technology Assessment, (“HTA”), amending Directive 2011/24/EU (“HTA Regulation”), was adopted in the EU. The Regulation entered into application on January 12, 2025 through a phased implementation. It is intended to boost cooperation among EU Member States in assessing health technologies, including new medicines, and providing the basis for cooperation at the EU level for joint clinical assessments in these areas. The Regulation permits EU Member States to use common HTA tools, methodologies, and procedures across the EU, working together in four main areas, including joint clinical assessment of the innovative health technologies with the most potential impact for patients, joint scientific consultations whereby developers can seek advice from HTA authorities, identification of emerging health technologies to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual EU Member States will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technologies, and making decisions on pricing and reimbursement. If we are unable to maintain favorable pricing and reimbursement status in EU Member States for product candidates that we may successfully develop and for which we may obtain regulatory approval, any anticipated revenue from and growth prospects for those product candidates in the EU could be negatively affected.

It will be expanded to orphan medicinal products in January 2028 and to all centrally authorized medicinal products as of 2030. Select high-risk medical devices also came into scope in 2026. It is intended to boost cooperation among EU Member States in assessing health technologies, including new medicines. The Regulation establishes a framework for joint clinical assessments, increasing cooperation among EU Member States on clinical aspects of health technology evaluation. Individual EU Member States will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technologies and making decisions on pricing and reimbursement.

In clinical trials of Livmarli in ALGS, the most commonly reported AEs were diarrhea, abdominal pain and vomiting, and were mostly mild to moderate in severity and transient in nature. Additionally, AEs reported in greater than 5% of patients included fat-soluble vitamin deficiency, nausea, liver transaminase increases, and bone fracture. The frequency of observed AEs has not increased over time. In the pivotal trial of Livmarli in PFIC, adverse reactions reported in greater than 5% of patients and greater than placebo included diarrhea, abdominal pain, increased transaminases, hematochezia or rectal hemorrhage, and bone fractures. Prescribing information for Livmarli includes warnings and precautions related to monitoring for and the risk of hepatotoxicity, gastrointestinal adverse reactions, fat-soluble vitamin deficiency and risk of propylene glycol toxicity (pediatric patients less than 5 years of age). In clinical trials of volixibat, the most common AEs reported were mild to moderate GI events (diarrhea, abdominal pain, nausea and vomiting) observed in the volixibat groups. In the interim analysis of the PBC VANTAGE study, the incidence of diarrhea in patients on volixibat was 77% with all cases mild to moderate; one patient discontinued the study due to an AE of diarrhea. The most common adverse reactions for Cholbam (≥1%) are diarrhea, reflux esophagitis, malaise, jaundice, skin lesion, nausea, abdominal pain, intestinal polyp, urinary tract infection, and peripheral neuropathy. The most common (> 20%) AEs seen in patients on chenodiol in the RESTORE clinical trial included diarrhea, constipation and headache.

We participate in, or are subject to, the Medicaid Drug Rebate Program, as administered by Centers for Medicare & Medicaid Services (“CMS”), and other federal and state government pricing programs in the U.S., and we may participate, or be asked to participate, in additional government pricing programs or supplemental rebates in the future. These programs generally require us to pay rebates or otherwise provide discounts to government payors in connection with drugs that are dispensed to beneficiaries/recipients of these programs. In some cases, such as with the Medicaid Drug Rebate Program, the rebates are based on pricing that we report to the government agencies that administer the programs. Pricing requirements and rebate/discount calculations are complex, vary among products and programs, and are often subject to interpretation by governmental or regulatory agencies and the courts. The requirements of these programs, including, by way of example, their respective terms and scope, change frequently. For example, on March 11, 2021, the American Rescue Plan Act of 2021 was signed into law, which eliminated the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer’s price (“AMP”), for single source and innovator multiple source drugs, effective January 1, 2024. Responding to current and future changes may increase our costs, and the complexity of compliance will be time consuming. Invoicing for rebates is provided in arrears, and there is frequently a time lag of up to several months between the sales to which rebate notices relate and our receipt of those notices, which further complicates our ability to accurately estimate and accrue for rebates related to the Medicaid program as implemented by individual states. Thus, there can be no assurance that we will be able to identify all factors that may cause our discount and rebate payment obligations to vary from period to period, and our actual results may differ significantly from our estimated allowances for discounts and rebates. Changes in estimates and assumptions may have a material adverse effect on our business, results of operations and financial condition. In addition, the U.S. Department of Health and Human Services (“HHS”) Office of Inspector General and other Congressional, enforcement and administrative bodies have recently increased their focus on pricing requirements for products, including, but not limited to the methodologies used by manufacturers to calculate AMP, and best price, for compliance with reporting requirements under the Medicaid Drug Rebate Program. Additionally, several states have a practice of asking, or are increasing activity in requesting supplemental rebates, for covered products. We are liable for errors associated with our submission of pricing data and for any overcharging of government payors. For example, failure to submit monthly/quarterly AMP and best price data on a timely basis could result in significant civil mo…

Any regulatory approvals that we receive may be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including post-market studies or clinical trials, and surveillance to monitor safety and effectiveness. The FDA may also require a REMS in order to approve a product candidate, which could entail requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Similarly, the European Commission may require a RMP in order to collect additional information on a medicine’s safety profile which may include plans for pharmacovigilance activities and measures to minimize risks. In addition, if the FDA, European Commission or comparable foreign regulatory authorities approve a product candidate, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, post-marketing obligations, storage, advertising, promotion, import, export and recordkeeping for the approved product will be subject to extensive and ongoing regulatory requirements. For example, we are subject to ongoing FDA and European Commission obligations and continued regulatory review with respect to, among other things, the manufacturing, processing, labeling, packaging, distribution, AE reporting, storage, advertising, promotion and recordkeeping for Livmarli, which requirements include submissions of safety and other post-marketing information and reports and registration, as well as continued compliance with current good manufacturing practices (“cGMP”) requirements and with the FDA’s and equivalent foreign good clinical practice (“GCP”). We are also subject to post-marketing obligations for Cholbam including the conduct and submission of registry studies.

Previous wording
The FDA’s, European Commission’s and comparable foreign regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval for our product candidates or restrict marketing of any then-approved product. 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, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations. For example, in April 2023 the European Commission adopted a proposal for a new Directive and Regulation to revise the existing pharmaceutical legislation. In April 2024, the Parliament adopted its related position and in June 2025, the European Council agreed on its position. The Council, the Parliament and the European Commission have begun trilogue negotiations with a view to reaching an agreement on the package. Regulatory exclusivities are a key topic of the negotiations. A decrease in data and market exclusivity opportunities for our product candidates in the EU could make them open to generic or biosimilar competition earlier than is currently the case with a related reduction in reimbursement status.

The additional clinical trials may not confirm the treatment effect, which may result in the loss of marketing authorization under accelerated approval, exceptional circumstances or conditional approval.

We may pursue approval in the U.S., Canada or certain countries in Europe using accelerated, exceptional circumstances or conditional approval pathways, which typically require commitments to complete additional clinical trials. The additional clinical trials may not confirm the treatment effect, which may result in the loss of marketing authorization under accelerated approval, exceptional circumstances or conditional approval. For example, the 24-week endpoint for the AZURE-1 and AZURE-4 trials is meant to enable accelerated approval of brelovitug for the treatment of chronic HDV infection. We expect that if approved, confirmatory studies will be required for full approval. Such confirmatory studies may not show the same clinical benefit as the studies that lead to accelerated approval.

Our clinical trials may not be successful and may not be completed on time or at all, and the FDA, EMA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials. For example, in certain of our ongoing clinical trials, the primary efficacy endpoint is a patient-reported outcome or a caregiver-reported outcome measuring the decrease in severity of pruritus. The FDA, EMA or comparable foreign regulatory authorities may not accept such patient-reported outcomes or caregiver-reported outcomes as validated. If modifications are needed for our study design to support the submission of an application for marketing approval, incorporating such modifications may be costly and could lead to delays in obtaining approval from the FDA, European Commission or comparable foreign regulatory authorities, which may significantly, adversely and materially affect our ability to successfully commercialize our product candidates. Further, even if we make changes to the study design to address these considerations, the FDA, European Commission or comparable foreign regulatory authorities may not approve our product candidates.

For example, each indication for which we are evaluating Livmarli and volixibat is a rare cholestatic liver disease with limited patient populations from which to draw participants in clinical trials. We will be required to identify and enroll a sufficient number of patients with the disease under investigation for each of our ongoing and planned clinical trials of Livmarli and volixibat. Potential patients may not be adequately diagnosed or identified with the diseases which we are targeting or may not meet the entry criteria for our trials. In addition, patients may ultimately decide not to enroll in a particular clinical trial for reasons outside of our control. We may seek to conduct clinical trials in countries in which we have not previously conducted trials for our product candidates and in which we have not yet worked with the competent regulatory authorities. As a result, we could face patient recruitment issues in certain countries where such foreign regulatory authorities are not familiar with our product candidates. Additionally, other pharmaceutical companies targeting the same cholestatic liver diseases are recruiting clinical trial patients from these patient populations, and have expanded access programs available, which have delayed enrollment in our clinical trials. Our inability to enroll a sufficient number of patients for any of our current or future clinical trials would result in significant delays. As a result, we may need to delay the completion of such trials beyond our expected timelines or abandon one or more clinical trials altogether.

Before obtaining regulatory approvals for the commercial sale of a product candidate, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that a product candidate is both safe and effective for use in each target indication. Our clinical trials have in the past and could in the future fail to demonstrate safety and efficacy of the product candidate studied for the target indication. For example, in December 2023, we announced that our Phase 2b EMBARK clinical trial evaluating Livmarli in patients with biliary atresia (“BA”) did not meet its primary or key secondary endpoints. Most product candidates that commence clinical trials are never approved by regulatory authorities for commercialization. In the case of our product candidates, we are seeking to develop treatments for rare diseases for which there is limited clinical experience, and our planned clinical trials use novel end points and measurement methodologies, which add complexity to the conduct of and analysis of data from our clinical trials and may delay or prevent regulatory approval.

Prior to obtaining approval to commercialize a product candidate in the U.S. or internationally, we must demonstrate with substantial evidence from adequate and well-controlled clinical trials, and to the satisfaction of the FDA, EMA or comparable foreign regulatory authorities, that such product candidates are safe and effective for their intended uses. Results from non-clinical studies and clinical trials can be interpreted in different ways. Even if we believe the non-clinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA, European Commission or comparable foreign regulatory authorities. The FDA, EMA or comparable foreign regulatory authorities, as the case may be, may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or may object to elements of our clinical development program. If we were required to conduct such additional preclinical studies or clinical trials, the FDA, EMA or comparable foreign regulatory authorities may not agree with our interpretation of the results and we may not receive approval for our product candidates or additional indications, or marketing of our approved medicines may be subject to additional requirements.

We plan to submit these data to the FDA and other regulatory authorities for approval of volixibat for the treatment of pruritus due to PSC, but regulatory authorities may not agree with our interpretation of the safety or efficacy data from the study and may not grant approval. In addition, while the NDA for zilurgisertib is supported by secondary endpoints, the pivotal study did not reach statistical significance on the primary endpoint. The FDA may determine that the clinical data for zilurgisertib is not sufficient to approve the NDA for the program. The FDA, EMA or comparable foreign regulatory authorities, as the case may be, may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or may object to elements of our clinical development program.

We plan to acquire rights to develop and commercialize product candidates in addition to our current approved medicines and our current product candidates. If we decide to pursue the development and commercialization of any additional product candidates, we may be required to invest significant resources to acquire or in-license the rights to such product candidates or to conduct drug discovery activities. We do not currently have the necessary drug discovery personnel or expertise adequate to discover and develop an additional product candidate on our own. Any other product candidates will require additional, time-consuming development efforts, and significant financial resources, prior to commercial sale, including preclinical studies, extensive clinical trials and approval by the FDA, European Commission or comparable foreign regulatory authorities. All product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and/or effective for approval by regulatory authorities. Because we have limited financial and personnel resources, we focus on specific product candidates for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or other indications that later prove to have greater commercial potential. We may focus our efforts and resources on product candidates that ultimately prove to be unsuccessful.

Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate effectiveness in the targeted indication or an acceptable safety profile, gain regulatory approval and become commercially viable. While we have three medicines approved for commercial sale, we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred substantial net losses since our inception in May 2018. For the nine months ended September 30, 2025 and 2024, we reported a net loss of $17.6 million and $64.2 million, respectively. As of September 30, 2025, we had an accumulated deficit of $661.8 million.

If the size of the market opportunities in each of our target indications or for any assets or product candidates that we may acquire, such as the Bile Acid Medicines, is smaller than we anticipate, we may not be able to achieve profitability and growth. We focus the clinical development and commercialization of our approved medicines on rare diseases with relatively small patient populations. Given the small number of patients who have the diseases that we are targeting, it is critical to our ability to grow and become profitable that we continue to successfully identify patients with these rare diseases. In addition, our estimates of the patient populations for our target indications have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations, and market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. The effort to identify patients with diseases we seek to treat is in early stages, and we cannot accurately predict the number of patients for whom treatment might be possible. Additionally, the potentially addressable patient population for each of our product candidates may be limited or may not be amenable to treatment with our product candidates, and new patients may become increasingly difficult to identify or gain access to, which would adversely affect our results of operations and our business. Lastly, the potentially addressable patient population for any of our potential indications may even be further reduced if gene therapy products become more widely accepted and approved.

Disruptions at the FDA, European Commission, EMA and other foreign regulatory authorities may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary regulatory authorities, which would adversely affect our business. For example, over the last several years, including beginning on October 1, 2025 and continuing to the present, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities to the extent they are not funded by existing available user fees. Repeated or prolonged government shutdowns or global health concerns could prevent the FDA, EMA or comparable foreign regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities and could significantly impact the ability of the FDA, European Commission, EMA or comparable foreign regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business. In addition, the current U.S. administration has enacted substantial reductions in force at various U.S. government agencies that, if applied to the FDA in a material way, could significantly reduce the FDA’s capacity to perform its functions in a manner consistent with its past practices and could negatively impact our business.

There have also been and continue to be a number of initiatives at the U.S. federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act (“Affordable Care Act”) was enacted in the U.S. Among the provisions of the Affordable Care Act of importance to our potential product candidates, the Affordable Care Act: established an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents; expanded eligibility criteria for Medicaid programs; increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program; creates a Medicare Part D coverage gap discount program; established a Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare & Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending.

Other legislative changes have been proposed and adopted in the U.S. since the Affordable Care Act was enacted. On July 4, 2025, the OBBBA was signed into law, which is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. The OBBBA also narrows access to Affordable Care Act marketplace exchange enrollment and declines to extend the Affordable Care Act enhanced advanced premium tax credits, set to expire at the end of 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance. Further, through the process created by the Budget Control Act of 2011,there are automatic reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and, due to subsequent legislative amendments to the statute, including the Bipartisan Budget Act of 2018 and the Consolidated Appropriations Act of 2023, will remain in effect until 2032 unless additional Congressional action is taken. Additionally, on March 11, 2021, the American Rescue Plan Act of 2021 was signed into law, which eliminates the statutory Medicaid drug rebate cap, previously set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, effective January 1, 2024.
Current wording
There have been amendments and executive, judicial and Congressional challenges to certain aspects of the Affordable Care Act. For example, on July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was signed into law, which narrowed access to Affordable Care Act marketplace exchange enrollment and declined to extend the Affordable Care Act enhanced advanced premium tax credits that expired at the end of 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance. The OBBBA also is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. Congress is considering proposed legislation intended to further reduce healthcare costs with alternatives to replace the expired Affordable Care Act subsidies. Any of these measures could reduce the number of insured individuals in the U.S. and thereby reduce access to reimbursement for our commercial medicines.
Previous wording
We expect that the Affordable Care Act, the IRA and other healthcare reform measures that may be adopted in the future may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from third-party payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our approved medicines and our product candidates, if approved. Further, the overall funding of certain government programs such as Medicaid and Medicare is uncertain and there is no guarantee that funds approved by the U.S. Congress will be made available by the current administration. The current administration is pursuing policies to reduce regulations and expenditures across government including at HHS, the FDA, CMS and related agencies. These actions, presently directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. These actions include, for example, (1) directives to reduce agency workforce; (2) rescinding a Biden administration executive order tasking the Center for Medicare and Medicaid Innovation to consider new payment and healthcare models to limit drug spending; (3) eliminating the Biden administration’s executive order that directed HHS to establish an AI task force and developing a strategic plan; (4) directing HHS and other agencies to lower prescription drug costs through a variety of initiatives, including by improving upon the Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (5) imposing tariffs on imported pharmaceutical products; (6) directing certain federal agencies to enforce existing law regarding hospital and plan price transparency and by standardizing prices across hospitals and health plans; and (7) as part of the Make America Healthy Again Commission's recent Strategy Report, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers’ global pricing strategies and profitability, while increasing their operational costs and compliance risks. In September 2025, the current administration announced the first agreement with a major pharmaceutical company that requires the drug manufacturer to offer, through a direct to consumer platform, U.S. patients and Medicaid programs prescription drug Most-Favored Nation pricing equal to or lower than those paid in other developed nations, with additional mandates for direct-to-patient discounts and repatriation of f…

The biopharmaceutical industry is characterized by intense competition and rapid innovation. Our potential competitors include major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies, generic pharmaceutical companies and universities and other research institutions who are active in rare disease. Many of our competitors have substantially greater financial, technical and other resources, such as larger research and development staff and experienced marketing and manufacturing organizations and well-established sales forces. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, drug products that are more effective or less costly than our product candidates, which may negatively affect our commercial opportunities. We believe the key competitive factors that will affect the development and commercial success of our product candidates are efficacy, safety and tolerability profile, reliability, convenience of dosing, price and reimbursement. There may also be competitors for our product candidates that we are unaware of at this point. Additionally, while our product candidates and approved medicines are generally protected for a defined period per jurisdiction by various patents, the loss of patent or regulatory exclusivity for our pharmaceutical products may open such products to competition from generic substitutes that are typically priced significantly lower than the original products. The introduction of generic versions of a pharmaceutical product frequently leads to a swift and substantial decline in the sales of the original product. Our continued innovation efforts cannot fully mitigate the impact of competition from generics.

We are aware Ipsen has received approval for odevixibat (Bylvay) for the treatment of pruritus in patients with PFIC 3 months of age and older, and cholestatic pruritus in patients with ALGS 12 months of age and older, in the U.S., and for the treatment of PFIC in patients 6 months of age and older in the EU and for odevixibat (Kayfanda) for the treatment of cholestatic pruritus in ALGS in patients 6 months of age and older. In the EU, Bylvay and Kayfanda are authorized under exceptional circumstances. Ipsen has opened enrollment in their ALGS open-label extension study to infants 11 months or younger and is also conducting a study of odevixibat in BA and plans to pursue other cholestatic liver diseases. GSK announced in November 2024 that the Phase 3 GLISTEN trial with linerixibat in PBC met its primary pruritus endpoint and that GSK has submitted a marketing applications to the U.S. and EU in the first half of 2025 with potential approvals expected in the first half of 2026.

Other off-label medications are also used in ALGS, PFIC, PSC and PBC for cholestatic pruritus such as Ursodeoxycholic acid (“UDCA”), cholestyramine and other bile salt resins, rifampin, naltrexone and other agents, such as selective serotonin reuptake inhibitors. Despite the lack of FDA approval, these older, generic agents are perceived as part of the standard of care for treating ALGS, PFIC, PSC and PBC patients suffering from cholestatic pruritus. Further, we may compete with companies that are developing gene therapy for the treatment of PFIC. Additionally, surgical interventions, such as partial external biliary diversion and nasobiliary drainage, and extracorporeal liver support, such as Molecular Adsorbent Recirculation System, are also employed in an attempt to lower bile acid levels, manage pruritus and improve measures of liver function.

Under the Hatch-Waxman Amendments of the Federal Food, Drug, and Cosmetic Act, a pharmaceutical manufacturer may file an ANDA seeking approval of a generic copy of an approved innovator product or an NDA under Section 505(b)(2) that relies on the FDA’s prior findings of safety and effectiveness in approving the innovator product. A Section 505(b)(2) NDA may be for a new or improved version of the original innovator product. Certain of our approved medicines, including Chenodal, Ctexli and Cholbam, are or may be subject to immediate competition from compounded and generic entrants, as the ANDA and NDA for these drug products have no remaining or current patent or non-patent exclusivity.

Further, as described in more detail in this Part II, Item 1A and Part II, Item 1 appearing elsewhere in this Quarterly Report on Form 10-Q, we have initiated litigation against certain parties alleging infringement of certain “Orange Book” listed patents covering LIVMARLI in accordance with the procedures set out in the Hatch-Waxman Act following the submission by such parties of ANDAs directed to generic versions of LIVMARLI. We cannot make any predictions about the final outcome of these matters or the timing thereof.

Regulatory authorities in some jurisdictions, including the U.S. and the EU, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the U.S., or a patient population of greater than 200,000 individuals in the U.S., but for which there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the U.S. In the EU, the European Commission, on the basis of the opinion of the EMA Committee for Orphan Medicinal Products (“COMP”), grants orphan drug designation for medicines to be developed for the diagnosis, prevention or treatment of diseases that are life-threatening or chronically debilitating, for which either no satisfactory method of diagnosis, prevention, or treatment exists, or if such method exists, the medicine is of significant benefit to those affected by such condition. To benefit from such designation, either the prevalence of such condition must not be more than five in 10,000 people across the EU or, if more prevalent, it must be unlikely that the marketing of the medicine would generate sufficient returns to justify the investment needed for its development. In September 2013, the FDA granted orphan drug status to Livmarli for the treatment of patients with PFIC and ALGS in the U.S. We also received orphan drug designation for Livmarli for PFIC and ALGS in the EU. In 2025, the FDA and COMP granted orphan drug designation for volixibat for PBC and PSC. The FDA granted orphan drug designation for chenodiol for the treatment of CTX in 2010. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug may be entitled to a period of marketing exclusivity, which precludes the FDA or the European Commission from approving another marketing application for the same drug (or, in the case of the European Commission, a similar drug) for the same indication for that time period. The applicable period is seven years in the U.S. and ten years in the EU, which may be extended by six months and two years, respectively, in the case of product candidates that have complied with the respective regulatory authority’s agreed upon pediatric investigation plan (“PIP”). There is, however, a legislative proposal pending in the EU that may modify the length of orphan market exclusivity, change the way in which market exclusivity is awarded to drugs with more than one approved orphan indication. The exclusivity period in the EU can be reduced to six years if at the end of the fifth year a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the …

Any of our existing relationships or any future relationships we enter into may require us to incur non-recurring and other charges, increase our near- and long-term expenditures, issue securities that dilute our existing stockholders or disrupt our management and business. In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for volixibat because it may be deemed to be at too early of a stage of development for collaborative effort, and third parties may not view volixibat as having the requisite potential to demonstrate safety and efficacy. If we license products or businesses, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture. Following a strategic transaction or license, we may not achieve the revenues or specific net income that justifies such transaction. Any delays in entering into new strategic partnership agreements related to our product candidates could delay the development and commercialization of our product candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations.

Although a substantial amount of our efforts are focused on the clinical development, potential regulatory approval and commercialization of our approved medicines and product candidates, a key element of our long-term strategy is to in-license, acquire, develop, market and commercialize a portfolio of products to treat patients with rare diseases. Because we do not have the necessary internal research and development capabilities, unless we build such capabilities internally, we will be dependent upon pharmaceutical companies, academic scientists and other researchers to sell or license products or technology to us. The success of this strategy depends partly upon our ability to identify and select promising biopharmaceutical product candidates and products, negotiate licensing or acquisition agreements with their current owners and finance these arrangements. The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex. Other companies, including some with substantially greater financial, marketing, sales and other resources, may compete with us for the license or acquisition of product candidates and approved medicines. We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. We may not be able to acquire the rights to additional approved medicines or product candidates on terms that we find acceptable, or at all. Further, any product candidate that we acquire may require additional development efforts prior to commercial sale, including preclinical or clinical testing and approval by the FDA, the European Commission and other similar regulatory authorities. All product candidates are prone to risks of failure during biopharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, any approved medicines that we acquire may not have the market potential we believe, be manufactured or sold profitably, or achieve market acceptance.

For example, the full benefits of the Bile Acid Portfolio Acquisition, including the anticipated financial contribution of newly acquired assets, may not be realized as expected, may be diminished due to competition or may not be achieved within the anticipated time frame, or at all. Failure to achieve the anticipated benefits of the Bile Acid Portfolio Acquisition or any other product or product candidate acquisition, could adversely affect our results of operations or cash flows, divert needed resources away from our current approved medicines and product candidates, decrease or delay any accretive effect of an acquisition and negatively impact the price of our common stock.

In the ordinary course of business, we transfer personal data from Europe (including from our European subsidiaries) and other jurisdictions to the U.S. or other countries. Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries.

Other jurisdictions may adopt or have already adopted similarly stringent data localization and/or cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the EEA and UK to the U.S. in compliance with law, such as the EEA standard contractual clauses, the UK’s International Data Transfer Agreement / Addendum, and the EU-U.S. Data Privacy Framework and the UK extension thereto (which allows for transfers to relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the U.S. If there is no lawful manner for us to transfer personal data from the EEA, the UK, or other jurisdictions, to the U.S., or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including limitations of our ability to conduct clinical trial activities in Europe and/or elsewhere, the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions (such as Europe) at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer personal data and work with partners, vendors and other third parties, and/or injunctions against our processing or transferring of personal data necessary to operate our business. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers of personal data to recipients outside Europe for allegedly violating the EU GDPR’s cross-border data transfer limitations. For example, in May 2023, the Irish Data Protection Commission determined that a major social media company’s use of the standard contractual clauses to transfer personal data from Europe to the U.

Some of these claims allow for the recovery of statutory damages on a per violation basis, and, if viable, carry the potential for monumental statutory damages, depending on the volume of data and the number of violations.

Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (3) imposing tariffs on imported pharmaceutical products; and (4) as part of the Make America Healthy Again Commission’s Strategy Report released in September 2025, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. Additionally, the current administration recently called on Congress to enact “The Great Healthcare Plan” to codify and expand Most-Favored Nation pricing, lower government subsidies to private insurance companies, increase healthcare price transparency, expand pharmaceutical drugs available for over-the-counter purchase, and enact restrictions on pharmacy benefit manager payment methodologies, among other things. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers’ global pricing strategies and profitability, while increasing their operational costs and compliance risks. Congress may introduce and ultimately pass health care related legislation that could impact the drug approval process and make changes to the Medicare Drug Price Negotiation Program created under the Inflation Reduction Act (“IRA”). Additionally, in its June 2024 decision in Loper Bright Enterprises v. Raimondo (“Loper Bright”), the U.S. Supreme Court greatly reduced judicial deference to regulatory agencies, which could increase successful legal challenges to federal regulations affecting our operations. We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. It is unclear how any such additional health care reform measures will impact our business.
