Acute-On-Chronic Liver Failure

– Pooled analysis from Phase 3 clinical trials highlights liver transplant rates in adult patients with HRS with rapid reduction in kidney function treated with TERLIVAZ1 – DUBLIN, Oct. 26, 2024 /PRNewswire/ -- Mallinckrodt plc, a global specialty pharmaceutical company, today announced a poster presentation on TERLIVAZ® (terlipressin) for injection in patients with hepatorenal syndrome (HRS) with rapid reduction in kidney function1 at Kidney Week 2024, the annual meeting of the American Society of Nephrology (ASN) taking place in San Diego from October 23-27, 2024. TERLIVAZ is the first and only FDA-approved product indicated to improve kidney function in adults with HRS with rapid reduction in kidney function,1 an acute and life-threatening condition requiring hospitalization.2 HRS involving rapid reduction in kidney function1 is estimated to affect more than 42,000 Americans annually, approximately 0.01% of the U.S. population,3 making it a very rare condition; and rates of hospitalizations are increasing.4 Please see Limitation of Use and Important Safety Information, including Boxed Warning, below. The poster presentation highlights a pooled analysis of data from the CONFIRM and REVERSE Phase 3 placebo-controlled trials of TERLIVAZ.5 The analysis examined the rates of hepatorenal syndrome-acute kidney injury (HRS-AKI) reversal, renal replacement therapy (RRT), and liver transplant (LT) among a subpopulation of patients listed for LT at baseline who met FDA label guidelines for treatment with TERLIVAZ (SCr <5 mg/dL, ACLF grade 0–2, and MELD score <35).5 In this patient subpopulation, treatment with TERLIVAZ increased the rate of HRS-AKI reversal and reduced the need for RRT at all time points assessed.5 The increase in HRS-AKI reversal with TERLIVAZ did not negatively impact the LT rate in patients listed for LT at baseline.5 The rate of HRS-AKI reversal was 43% in the TERLIVAZ group (n=53) and 20% in the placebo group (n=35).5 The rate of RRT in the TERLIVAZ and placebo groups was 28% and 46% by Day 30; 32% and 54% by Day 60; and 36% and 54% by Day 90, respectively.5 The LT rate was similar in the TERLIVAZ and placebo groups at all time points assessed: 53% and 51% by Day 30; 66% and 57% by Day 60; and 66% and 63% by Day 90, respectively.5 The limitations of this study include, but are not limited to, small sample sizes, variables in methodology, and possible errors and omissions within the data sets.5 "This analysis of data from our Phase 3 trials furthers our understanding of the appropriate patient subpopulations and the potential impact of treatment on liver transplantation rates," said Peter Richardson, MRCP (UK), Executive Vice President & Chief Scientific Officer. "For these critically ill patients with HRS-AKI, a liver transplant is the definitive treatment, and we know there are significant challenges associated with RRT; which makes continued research important." This study was sponsored by Mallinckrodt Pharmaceuticals.

Patients with a serum creatinine >5 mg/dL are unlikely to experience benefit. IMPORTANT SAFETY INFORMATION WARNING: SERIOUS OR FATAL RESPIRATORY FAILURE TERLIVAZ may cause serious or fatal respiratory failure. Patients with volume overload or with acute-on-chronic liver failure (ACLF) Grade 3 are at increased risk. Assess oxygenation saturation (e.g., SpO2) before initiating TERLIVAZ. Do not initiate TERLIVAZ in patients experiencing hypoxia (e.g., SpO2 <90%) until oxygenation levels improve. Monitor patients for hypoxia using continuous pulse oximetry during treatment and discontinue TERLIVAZ if SpO2 decreases below 90%. Contraindications TERLIVAZ is contraindicated: In patients experiencing hypoxia or worsening respiratory symptoms. In patients with ongoing coronary, peripheral, or mesenteric ischemia. Warnings and Precautions Serious or Fatal Respiratory Failure: Obtain baseline oxygen saturation and do not initiate TERLIVAZ in hypoxic patients. Monitor patients for changes in respiratory status using continuous pulse oximetry and regular clinical assessments. Discontinue TERLIVAZ in patients experiencing hypoxia or increased respiratory symptoms. Manage intravascular volume overload by reducing or discontinuing the administration of albumin and/or other fluids and through judicious use of diuretics. Temporarily interrupt, reduce, or discontinue TERLIVAZ treatment until patient volume status improves. Avoid use in patients with ACLF Grade 3 because they are at significant risk for respiratory failure. Ineligibility for Liver Transplant: TERLIVAZ-related adverse reactions (respiratory failure, ischemia) may make a patient ineligible for liver transplantation, if listed. For patients with high prioritization for liver transplantation (e.g., MELD ≥35), the benefits of TERLIVAZ may not outweigh its risks. Ischemic Events: TERLIVAZ may cause cardiac, cerebrovascular, peripheral, or mesenteric ischemia. Avoid use of TERLIVAZ in patients with a history of severe cardiovascular conditions or cerebrovascular or ischemic disease. Discontinue TERLIVAZ in patients who experience signs or symptoms suggestive of ischemic adverse reactions. Embryo-Fetal Toxicity: TERLIVAZ may cause fetal harm when administered to a pregnant woman. If TERLIVAZ is used during pregnancy, the patient should be informed of the potential risk to the fetus. Adverse Reactions The most common adverse reactions (≥10%) include abdominal pain, nausea, respiratory failure, diarrhea, and dyspnea.

SAN DIEGO, Oct. 22, 2024 (GLOBE NEWSWIRE) -- Gyre Therapeutics, Inc. (“Gyre”) (Nasdaq: GYRE), a self-sustainable, commercial-stage biotechnology company with clinical development programs focusing on a variety of chronic organ diseases, today announced that the last patient in Gyre Pharmaceuticals’ pivotal Phase 3 trial in the People’s Republic of China (“PRC”) evaluating F351 (hydronidone) for Chronic Hepatitis B (“CHB”)-associated liver fibrosis has completed the 52-week study. Gyre Pharmaceuticals expects to report topline data from this trial by the first quarter of 2025. “The final patient completing our pivotal F351 Phase 3 trial marks an important milestone for Gyre and our development pipeline. We are grateful to the patients, researchers, trial investigators, and various teams who supported this trial and look forward to sharing data in the first quarter of 2025,” said Han Ying, Ph.D., CEO of Gyre Therapeutics. “Furthermore, we are excited to potentially use these results to spur initiation of our Phase 2 clinical trial in the United States evaluating F351 for Metabolic Dysfunction-Associated Steatohepatitis (“MASH”)-associated fibrosis in 2025.” The randomized, double-blind, placebo-controlled, multicenter Phase 3 trial (NCT05115942) enrolled 248 patients across 39 clinical research hospitals in the PRC. Patients were randomized 1:1 to receive either F351 or placebo in addition to entecavir antiviral basic therapy for CHB. The primary endpoint is a decrease in liver fibrosis (as measured by the Ishak Scoring System) by at least one stage after 52 weeks of treatment relative to baseline. China’s National Medical Products Administration (“NMPA”) designated F351 as a “Breakthrough Therapy” in 2021. About Hydronidone (F351) F351 is a structural analogue of the approved anti-fibrotic drug Pirfenidone (approved in the PRC for the treatment of idiopathic pulmonary fibrosis) and has been shown to inhibit in vitro both p38γ kinase activity and TGF-β1-induced excessive collagen synthesis in hepatic stellate cells (“HSCs”), which are recognized as critical event in the development and progression of fibrosis in the liver. This is further supported by its anti-proliferative effects on the HSCs in the liver. In vitro anti-fibrotic effects of F351 were also confirmed in several established in vivo models of liver fibrosis, such as CCI4-induced liver fibrosis mouse model, DMN-induced liver fibrosis rat model, and HSA-induced liver rat model, as well as mouse model of MASH fibrosis (CCI4+Western High Fat Diet). About Gyre Therapeutics Gyre Therapeutics is a biopharmaceutical company headquartered in San Diego, CA, with a primary focus on the development and commercialization of F351 (Hydronidone) for the treatment of MASH-associated fibrosis in the U.S. Gyre’s development strategy for F351 in MASH is based on the Company’s experience in MASH rodent model mechanistic studies and CHB-induced liver fibrosis clinical studies. Gyre is also advancing a diverse pipeline in the PRC through its indirect controlling interest in Gyre Pharmaceuticals, including ETUARY therapeutic expansions, F573, F528, and F230. About Gyre Pharmaceuticals Gyre Pharmaceuticals is a commercial-stage biopharmaceutical company committed to the research, development, manufacturing and commercialization of innovative drugs for organ fibrosis. Its flagship product, ETUARY (Pirfenidone capsule), was the first approved treatment for IPF in the PRC in 2011 and has maintained a prominent market share (2023 net sales of $112.1 million). In addition, Gyre Pharmaceuticals is evaluating F351 in a Phase 3 clinical trial in CHB-associated liver fibrosis in the PRC, which is expected to readout topline data by the first quarter of 2025. F351 received Breakthrough Therapy designation by the National Medical Products Administration’s Center for Drug Evaluation in March 2021. Gyre Pharmaceuticals is also developing treatments for COPD, PAH and ALF/ACLF. In October 2023, Gyre Therapeutics acquired an indirect majority interest in Gyre Pharmaceuticals (also known as Beijing Continent Pharmaceuticals Co., Ltd.).
