Study of Macitentan (ACT-064992) on Morbidity and Mortality in Patients With Symptomatic Pulmonary Arterial Hypertension

Summary

The AC-055-302/SERAPHIN study will be an event-driven Phase III study, comparing two different doses of macitentan (ACT-064992) (3 and 10 mg) vs placebo in patients with symptomatic PAH. The main study objective is to demonstrate that macitentan (ACT-064992) prolongs time to the first morbidity or mortality event, and to evaluate the benefit/risk profile of macitentan (ACT-064992) in the treatment of patients with symptomatic PAH.
