The purpose of this study is to assess the safety and efficacy of Rodatristat Ethyl in pulmonary arterial hypertension (PAH) patients.

Official Title

A Phase 2, Dose-Ranging, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study of Rodatristat Ethyl in Patients With Pulmonary Arterial Hypertension


Rodatristat Ethyl is a peripherally restricted TPH inhibitor being studied as a potential treatment for PAH. This dose-ranging, randomized, double-blind, placebo-controlled, multicenter study will evaluate the effect of Rodatristat Ethyl from baseline on pulmonary vascular resistance as measured at right heart catheterization. Patients will be enrolled into a main study with an option to enroll into an open label extension. The study is expected to enroll patients in the USA, Canada and Europe.
