GYRE Gyre Therapeutics Inc

Gyre Therapeutics (“Gyre”) (Nasdaq: GYRE), a clinical-stage, self-sustainable biotechnology company developing anti-fibrotic therapeutics for a variety of chronic organ diseases, today announced that the Center for Drug Evaluation (“CDE”) of China’s National Medical Products Administration (“NMPA”) has approved Gyre Pharmaceuticals’ (Gyre’s indirectly controlled subsidiary) Investigational New Drug (“IND”) application for F230 tablets, a selective endothelin receptor antagonist, for the treatment of pulmonary arterial hypertension (“PAH”). F230 was originally licensed from Eisai through Gyre’s indirect majority stockholder, GNI Group Ltd.

“PAH is a rare disease and a progressive, life-threatening disorder that represents a significant unmet need with no known cure,” said Han Ying, Ph.D., Chief Executive Officer of Gyre. “Through Gyre Pharmaceuticals, we are committed to advancing F230 through clinical development with the ultimate goal of improving patient outcomes and enhancing the quality of life for those affected by this devastating condition.”

In preclinical animal studies, F230 resulted in significant decreases of, or exhibited a decrease trend based on different dose groups in, mean pulmonary arterial pressure, right ventricular systolic pressure, right ventricular/left ventricular plus septum and pulmonary artery wall thickness. Even at the minimum effective dosage, the differences of those indexes between the treatment group and the PAH model group were statistically significant. In addition to PAH, Gyre is also exploring other disease indications for F230.
