SAN DIEGO, March 31, 2025 (GLOBE NEWSWIRE) -- Gyre Therapeutics (“Gyre”) (Nasdaq: GYRE), an innovative, commercial-stage biotechnology company focused on organ fibrosis, today announced that the National Medical Products Administration (NMPA) of the People’s Republic of China (“PRC”) has approved its clinical trial application for a potential new indication for pirfenidone in oncology-related pulmonary complications. The trial will evaluate pirfenidone capsules for the treatment of radiation-induced lung injury (RILI), with or without immune-related pneumonitis (CIP). This regulatory milestone marks the expansion of pirfenidone beyond its established role in idiopathic pulmonary fibrosis (IPF) into the oncology supportive care space, offering a novel lung-protective strategy for cancer patients undergoing radiation therapy or immunotherapy. In accordance with the NMPA approval, Gyre intends to pursue an adaptive Phase 2/3 clinical trial design, combining dose exploration with efficacy confirmation, to efficiently evaluate pirfenidone's potential in this new indication. Radiation-Induced Lung Injury (RILI): Radiation therapy is a cornerstone of lung cancer treatment. However, 5%–25% of patients experience lung damage due to radiation exposure, limiting the ability to escalate doses and thereby compromising treatment efficacy. Checkpoint Inhibitor Pneumonitis (CIP): Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, but 13%–19% of patients develop CIP. This condition accounts for approximately 35% of immune-related adverse event (irAE) deaths and often necessitates treatment discontinuation. Currently, no targeted therapies exist for lung injuries caused by radiation or immunotherapy. Distinguishing between RILI and CIP is challenging, particularly when both occur concurrently. Corticosteroids remain the standard of care despite significant long-term side effects. By targeting and inhibiting fibrotic pathways, pirfenidone may address the root cause of lung injury progression, offering a new treatment option for patients receiving radiation or immunotherapy. Gyre anticipates initiating the trial in the second half of 2025 at leading academic and oncology centers across the PRC. About PirfenidonePirfenidone is an orally administered small molecule approved for the treatment of IPF. It works by inhibiting TGF-β signaling and fibroblast proliferation. The drug has demonstrated clinical benefit in slowing lung function decline in IPF and is now being evaluated for oncology-related pulmonary complications. Gyre has held first-in-class status for pirfenidone in the PRC since its original approval in 2011, underscoring its pioneering role in treating fibrotic lung diseases. About Gyre TherapeuticsGyre Therapeutics is a biopharmaceutical company headquartered in San Diego, CA, primarily focused on the development and commercialization of F351 (Hydronidone) for MASH-associated fibrosis in the U.S. Gyre’s strategy builds on its experience in mechanistic studies using MASH rodent models and clinical studies in CHB-induced liver fibrosis. In the PRC, Gyre is advancing a broad pipeline through its indirect controlling interest in Gyre Pharmaceuticals, including therapeutic expansions of ETUARY, and development programs for F573, F528, and F230.

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).
