GNI Group (TYO:2160) said its subsidiary Gyre Therapeutics has begun dosing in a Phase 1 trial of F230, a treatment candidate for pulmonary arterial hypertension (PAH), in China, according to a Wednesday filing on the Tokyo Stock Exchange.
F230, a selective endothelin A receptor antagonist originally developed by Eisai, was licensed to GNI in 2020. The trial will assess safety, tolerability, and pharmacokinetics in healthy volunteers.
GNI said the move expands Gyre's fibrosis-focused pipeline, which includes lead drug Hydronidone, into cardiovascular disease.
