Gyre Therapeutics Communicates Hydronidone Application with China's Drug Administration
Gyre Therapeutics announced that its majority-owned subsidiary in China, Gyre Pharmaceuticals Co., Ltd., completed a Pre-New Drug Application communication meeting with the Center for Drug Evaluation of China's National Medical Products Administration regarding Hydronidone, the company's first-in-class anti-fibrotic therapy. During the meeting, Gyre Pharmaceuticals and the CDE reached consensus that existing Phase 3 clinical data for Hydronidone, based on histologic improvement in liver fibrosis as measured by the Ishak fibrosis score, are generally supportive of submission of a conditional approval NDA for the treatment of chronic hepatitis B-associated liver fibrosis, including early cirrhosis. The CDE further indicated that Hydronidone meets the criteria for inclusion in China's Priority Review and Approval Program for Innovative Drugs, subject to formal filing, acceptance and regulatory review. The NMPA previously granted Hydronidone Breakthrough Therapy Designation in March 2021, recognizing its potential to address a serious condition with significant unmet medical need. This designation supports eligibility for priority review, which is intended to facilitate an accelerated regulatory review process for innovative therapies. As part of the agreed regulatory pathway, the company plans to conduct an additional confirmatory clinical trial, referred to as a Phase 3c trial in China, designed to evaluate liver-related clinical outcomes to support potential conversion from conditional approval to regular approval. The company currently expects to submit an NDA for conditional approval of Hydronidone in the first half of 2026, subject to final data readiness and applicable regulatory procedures.
