– New findings to be presented at the 2025 European Association for the Study of the Liver (EASL) Congress continue to demonstrate the effectiveness of Livdelzi (seladelpar) in reducing pruritus in people with primary biliary cholangitis (PBC) – – Additional presentations will showcase the potential for maintained virologic response following treatment with investigational bulevirtide in people with hepatitis delta virus (HDV) – – Presentations in hepatitis B virus (HBV) and hepatitis C virus (HCV) will underscore Gilead’s commitment to advancing scientific research and our understanding of viral hepatitis in the real-world setting – FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq:GILD) today announced new research to be presented at the European Association for the Study of the Liver (EASL) Congress, May 7-10, 2025, Amsterdam, furthering Gilead’s commitment to transform the lives of people living with liver disease. New data to be presented at EASL will include a subgroup analysis from ASSURE, an ongoing open-label study, and an analysis of the Phase 3 RESPONSE trial and the open-label extension. Data will reinforce the effectiveness of Livdelzi® (seladelpar), known as Lyvdelzi® in the European Union, in reducing pruritus (chronic itch), a debilitating common symptom of primary biliary cholangitis (PBC). Moreover, the results will highlight seladelpar’s ability to deliver a sustained biochemical response regardless of prior treatment history, and as an option for a broad range of people with PBC. “Our focus remains on addressing the areas of greatest unmet need across liver diseases,” said Dietmar Berger, MD, PhD, Chief Medical Officer, Gilead Sciences. “Our deep expertise in treating liver disease has delivered the first and only treatment for hepatitis delta and the first treatment for primary biliary cholangitis that has demonstrated statistically significant improvements across both chronic itch and markers of disease progression. Our studies continue to deliver transformational insights and therapies to help foster healthier futures for the millions of people who live with viral hepatitis and those who live with less prevalent liver conditions with remaining high unmet needs.” Key findings from 29 accepted abstracts will include two oral presentations showcasing new data on the critical goal of maintained virologic response following treatment with 2 mg and 10 mg bulevirtide in people living with hepatitis delta virus (HDV). These findings build on the wealth of long-term data for the treatment of chronic HDV. A late breaker presentation on the final results from the pivotal MYR301 Phase 3 study evaluating the efficacy and safety of 2 mg and 10 mg bulevirtide as monotherapy will reveal long-term response rates, including the proportion of participants with undetectable virus levels two years after treatment cessation. In hepatitis B (HBV), Gilead will present initial results from a Phase 1a study of a novel investigational therapeutic vaccine that shows early promise towards the goal of achieving a functional cure for HBV infection. A separate analysis of real-world data showed that individuals with low-level HBV viremia still have a risk of negative events. Additionally, a retrospective analysis of participants enrolled in two Phase 3 studies evaluating Vemlidy® (tenofovir alafenamide) using a risk score for liver cancer highlights the importance of treatment to help reduce liver cancer risk. Gilead will also showcase real-world data on hepatitis C (HCV), demonstrating the effects of direct-acting antivirals (DAA) against all genotypes of the virus across diverse geographical regions, supporting the global applicability of HCV treatment guidelines. In addition, new real-world insights will show that the choice of DAA for people living with HCV taking other medicines, such as antipsychotics, was associated with reducing the problem of drug-drug interactions. To help raise awareness about HCV and encourage people to get screened for the disease, Gilead will again support EASL’s “Love Your Liver” Campaign at the congress. At the EASL Congress, Gilead, in collaboration with the PBC Foundation and Friends of the PBC Foundation, will also launch “All the Feelings with PBC,” a campaign highlighting the experiences of people living with PBC and emphasizing the importance of listening to and addressing their needs in clinical practice and research. The campaign will feature paintings by Berlin-based artist, Nour Khwies, based on the physical and emotional experiences of people living with PBC: Dilek from Germany, Angela from Scotland, Joana from Portugal, and L. Marie from the United States, whose painting will be painted live at EASL.

Marketing Authorization In July 2023, the European Commission (EC) granted full Marketing Authorization (MA) for Hepcludex® (bulevirtide) 2 mg for the treatment of adults with chronic HDV and compensated liver disease. Bulevirtide was initially granted a conditional MA from the EC in July 2020 to provide people living with HDV urgent access to treatment. Bulevirtide’s conditional MA license in the UK was converted to a full MA in August 2023, and a full MA was granted in Switzerland in February 2024. In regions where bulevirtide is not approved, including the U.S., bulevirtide 2 mg is an investigational product. In these regions, health authorities have not established the safety and efficacy of bulevirtide. Bulevirtide 10 mg is an investigational product and is not approved anywhere globally. In February 2025, the European Commission (EC) granted conditional marketing authorization for Lyvdelzi® (seladelpar) for the treatment of PBC in combination with ursodeoxycholic acid (UDCA) in adults who have an inadequate response to UDCA alone, or as monotherapy in those unable to tolerate UDCA. Lyvdelzi provides an important treatment option for people living with PBC in the European Economic Area (EEA). Gilead is working with health authorities across Europe to ensure people living with PBC who are eligible for Lyvdelzi have access as soon as possible. Continued approval of Lyvdelzi for the approved indication will be contingent on verification and description of clinical benefit in confirmatory trial(s). Lyvdelzi has Priority Medicine (PRIME) designation in the EU, assigned to optimize the development of novel medicines that target conditions with an unmet medical need for which no treatment options exist or where they can offer a major therapeutic advantage over existing treatments, as well as well as Orphan Drug Designation for the treatment of people living with PBC. Livdelzi® received conditional approval from the UK Medicines and Healthcare products Regulatory Agency (MHRA) in January 2025. In the U.S., Livdelzi® obtained accelerated approval for the treatment of PBC by the U.S. Food and Drug Administration (FDA) in August 2024. Livdelzi received Breakthrough Therapy Designation, as well as Orphan Drug Designation for the treatment of people living with PBC. As part of the FDA accelerated approval, Gilead has committed to AFFIRM, a long-term outcomes study, which has begun in people with compensated cirrhosis. Continued U.S. approval may be contingent upon verification of clinical benefit in confirmatory trial(s). Regulatory review for Livdelzi is underway in Canada, Australia, and Switzerland. U.S. Indication for Livdelzi® Livdelzi is indicated for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have had an inadequate response to UDCA, or as monotherapy in patients unable to tolerate UDCA. The FDA approved this indication under accelerated approval based on a reduction of alkaline phosphatase (ALP). Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Limitations of Use: Use of Livdelzi is not recommended in patients who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy). U.S. Important Safety Information for Livdelzi Warnings and Precautions Fractures: Fractures occurred in 4% of Livdelzi-treated patients compared to no placebo-treated patients. Consider the risk of fracture in the care of patients treated with Livdelzi and monitor bone health according to current standards of care. Liver Test Abnormalities: Livdelzi has been associated with dose-related increases in serum transaminase (AST and ALT) levels > 3 x ULN in patients receiving 50 mg and 200 mg once daily (5x and 20x higher than the recommended dosage of 10 mg once daily). Perform baseline clinical and laboratory testing when starting Livdelzi® and monitor thereafter according to routine patient management. Interrupt treatment if the liver tests (ALT, AST, total bilirubin, and/or ALP) worsen, or if the patient develops signs and symptoms of clinical hepatitis (eg, jaundice, right upper quadrant pain, eosinophilia). Consider permanent discontinuation if liver tests worsen after restarting Livdelzi. Biliary Obstruction: Avoid use of Livdelzi in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt Livdelzi and treat as clinically indicated. Adverse Reactions The most common adverse reactions (≥5%) with Livdelzi were headache (8%), abdominal pain (7%), nausea (6%), abdominal distension (6%), and dizziness (5%). Drug Interactions OAT3 Inhibitors and Strong CYP2C9 Inhibitors: Avoid co-administration with L due to increased Livdelzi exposure. Rifampin: Monitor biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during Livdelzi treatment. Coadministration may result in delayed or suboptimal biochemical response of Livdelzi. Dual Moderate CYP2C9 and Moderate-to-Strong CYP3A4 Inhibitors and BCRP Inhibitors (e.g., cyclosporine): Monitor closely for adverse effects. Concomitant administration with Livdelzi may increase Livdelzi exposure. CYP2C9 Poor Metabolizers Using Moderate-to-Strong CYP3A4 Inhibitors: Monitor more frequently for adverse reactions as concomitant use of a moderate-to-strong CYP3A4 inhibitor in patients who are CYP2C9 poor metabolizers may increase Livdelzi exposure and risk of LIVDELZI adverse reactions. Bile Acid Sequestrants: Administer Livdelzi at least 4 hours before or 4 hours after taking a bile acid sequestrant, or at as great an interval as possible. Pregnancy and Lactation Pregnancy: There is insufficient data from human pregnancies exposed to Livdelzi to allow an assessment of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Report pregnancies to Gilead Sciences, Inc., at 1-800-445-3235. Lactation: There is no data on the presence of Livdelzi in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Livdelzi and any potential adverse effects on the breastfed infant from Livdelzi. U.S. Indication for Vemlidy® VEMLIDY is indicated for the treatment of chronic hepatitis B virus infection in adults and pediatric patients six years of age and older and weighing at least 25 kg with compensated liver disease. U.S. Important Safety Information for and Indication for the Use of Vemlidy BOXED WARNING: POSTTREATMENT SEVERE ACUTE EXACERBATION OF HEPATITIS B Discontinuation of anti-hepatitis B therapy, including VEMLIDY, may result in severe acute exacerbations of hepatitis B. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy, including VEMLIDY. If appropriate, resumption of anti-hepatitis B therapy may be warranted. Warnings and Precautions Risk of Development of HIV-1 Resistance in HBV/HIV-1 Coinfected Patients:Due to this risk, VEMLIDY alone should not be used for the treatment of HIV-1 infection. Safety and efficacy of VEMLIDY have not been established in HBV/HIV-1 coinfected patients. HIV antibody testing should be offered to all HBV-infected patients before initiating therapy with VEMLIDY, and if positive, an appropriate antiretroviral combination regimen that is recommended for HBV/HIV-1 coinfected patients should be used. New Onset or Worsening Renal Impairment:Postmarketing cases of renal impairment, including acute renal failure, proximal renal tubulopathy (PRT), and Fanconi syndrome, have been reported with TAF-containing products. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue VEMLIDY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Monitor renal function in all patients – See Dosage and Administration. Lactic Acidosis and Severe Hepatomegaly with Steatosis:Fatal cases have been reported with the use of nucleoside analogs, including tenofovir disoproxil fumarate (TDF). Discontinue VEMLIDY if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations. Adverse Reactions Most common adverse events in the week 96 pediatric population reported in ≥5% were: nasopharyngitis, headache, COVID-19, pyrexia, diarrhea, upper respiratory tract infection, cough, respiratory tract infection viral, abdominal pain upper. Overall, abdominal pain upper and metabolic nephropathy were the only study drug–related adverse events, which occurred in > 1 participant, reported in 2.3% (2/88 participants) each. Drug Interactions Coadministration of VEMLIDY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of tenofovir and the risk of adverse reactions. Coadministration of VEMLIDY is not recommended with the following: oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, or St. John’s wort. Such coadministration is expected to decrease the concentration of tenofovir alafenamide, reducing the therapeutic effect of VEMLIDY. Drugs that strongly affect P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) activity may lead to changes in VEMLIDY absorption. Coadministration of VEMLIDY with carbamazepine, the tenofovir alafenamide dose should be increased to two tablets once daily. Consult the full prescribing information for VEMLIDY for more information on potentially significant drug interactions, including clinical comments. Dosage and Administration Testing Prior to Initiation:HIV infection. Prior to or When Initiating, and During Treatment:On a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Dosage:1 tablet taken once daily with food. Renal Impairment:Not recommended in patients with end-stage renal disease (ESRD; eCrCl <15 mL/min) who are not receiving chronic hemodialysis; in patients on chronic hemodialysis, on hemodialysis days, administer VEMLIDY after completion of hemodialysis treatment. No data are available to make dose recommendations in pediatric patients with renal impairment. Hepatic Impairment:Not recommended in patients with decompensated (Child-Pugh B or C) hepatic impairment.

Strong Use of Composition-of-Matter Coverage: Patent protects the molecular structure of RHB-107, providing market exclusivity beyond method-of-use claims COVID-19 Therapeutic Use: Includes coverage for treatment of SARS-CoV-2, including wild-type and emerging variants This patent grant enhances RedHill's strategic positioning in the global COVID-19 therapeutic space, a market still expected to be worth more than $3 billion in 2025[1], and expands its patent footprint in Asia, a key pharmaceutical market RHB-107 successfully met the primary endpoint of safety and tolerability, delivering promising reduction in hospitalization efficacy results in a U.S. Phase 2 COVID-19 study[2]. Additional clinical data expected from the externally non-dilutive funded PROTECT study, supported by the U.S. Department of Defense RHB-107 is a novel, patient-friendly oral, once-daily, host-directed potential broad-acting antiviral expected to act independently of viral spike protein mutations[3] RALEIGH, N.C. and TEL-AVIV, Israel, April 28, 2025 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced that the China National Intellectual Property Administration ("CNIPA") has formally allowed a critical use of composition-of-matter patent for RedHill's proprietary investigational compound RHB-107 (upamostat), a potential oral treatment for COVID-19 (patent application No. 202311591091.6). "This newly allowed Chinese patent application is a significant success, enhancing RedHill's strategic positioning in the global COVID-19 therapeutic space – a market still expected to be worth more than three billion dollars in 2025. It provides broad and robust protection of the use of RHB-107, including its structure in oral formulations targeting SARS-CoV-2 infections, including both wild-type and naturally occurring variants and expanding its patent footprint in Asia, a key pharmaceutical market," said Guy Goldberg, RedHill's Chief Business Officer. "It underscores the uniqueness of our antiviral candidate and further strengthens our global intellectual property portfolio as we advance development of a much-needed oral candidate for early, community-based (non-hospitalized) treatment of COVID-19, which still represents a considerable threat to vulnerable patients. As a novel, potentially broad-acting, host-directed antiviral that is expected to act independently of viral spike protein mutations, RHB-107, if approved, could provide a much-needed additional option for use in the early COVID-19 treatment space, alongside Pfizer's Paxlovid." Data from RHB-107's U.S. Phase 2 study, published in the International Journal of Infectious Diseases, showed a 100% reduction in hospitalization due to COVID-19, with zero patients (0/41) on the RHB-107 arms versus 15% (3/20) hospitalized for COVID-19 on the placebo-controlled arm (nominal p-value=0.0317). The study also showed an approximately 88% reduction in reported new severe COVID-19 symptoms after treatment initiation, with new severe COVID-19 symptoms reported by only 2.4% of the RHB-107 treated group (1/41) compared to 20% (4/20) of patients in the placebo-controlled arm (nominal p-value=0.036). Further post-hoc analysis showed faster recovery periods from severe COVID-19 symptoms with a median of 3 days to recovery with RHB-107 compared to 8 days with placebo. Additional clinical data is expected from the externally non-dilutive funded PROTECT study, supported by the U.S. Department of Defense. About RHB-107 (upamostat) RHB-107 is a proprietary, first-in-class, once-daily orally administered investigational antiviral, that targets human serine proteases involved in preparing the spike protein for viral entry into target cells. Because it is host-cell targeted, RHB-107 is expected to also be effective against emerging viral variants with mutations in the spike protein. RHB-107 is well tolerated; in the initial COVID-19 study, among 41 patients only one reported a drug-related adverse reaction (a mild, self-limited, rash). In addition, RHB-107 inhibits several proteases targeting cancer and inflammatory gastrointestinal disease. RHB-107 has undergone several Phase 1 studies and two Phase 2 studies, demonstrating its clinical safety profile in approximately 200 patients[4]. RedHill acquired the exclusive worldwide rights to RHB-107, excluding China, Hong Kong, Taiwan and Macao, from Germany's Heidelberg Pharma AG (FSE: HPHA) (formerly WILEX AG) for all indications.
