Description
Summary
The objective of this study is to evaluate the effects of sotatercept treatment (plus maximum tolerated background PAH therapy) versus placebo (plus maximum tolerated background PAH therapy) on time to first event of all cause death, lung transplantation, or PAH worsening-related hospitalization of ≥ 24 hours, in participants with WHO FC III or FC IV PAH at high risk of mortality.
Official Title
A Phase 3, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate Sotatercept When Added to Maximum Tolerated Background Therapy in Participants With Pulmonary Arterial Hypertension (PAH) World Health Organization (WHO) Functional Class (FC) III or FC IV at High Risk Mortality
Details
Study A011-14 is a Phase 3, randomized, double-blind, placebo-controlled study to evaluate sotatercept when added to maximum tolerated background PAH therapy on time to first event of all-cause death, lung transplantation, or PAH worsening related hospitalization of ≥ 24 hours, in participants with WHO FC IV PAH or WHO FC III PAH at high risk of mortality. Participants with symptomatic PAH (WHO FC III or FC IV at high risk of mortality) who present with idiopathic or heritable PAH, PAH associated with connective tissue diseases (CTD), drug- or toxin-induced, post-shunt correction PAH, or PAH presenting at least 1 year following the correction of congenital heart defect. Participants must have a Registry to Evaluate Early and Long-Term PAH Disease Management (REVEAL) Lite 2 risk score of ≥ 10 and be on maximum tolerated combination background PAH therapy.
