A Study of Rodatristat Ethyl in Patients With Pulmonary Arterial Hypertension (Core OLE)

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.
