- Allocation: RandomizedIntervention Model: Parallel AssignmentIntervention Model Description: Participants will be randomized to one of two treatment arms to receive either sotatercept (0.7 mg/kg) by subcutaneous administration once every 3 weeks, or placebo. All participants will be on concurrent, stable background PAH therapy. Randomization will be stratified by baseline WHO Functional Class (Class II or III) and by background PAH therapy (mono/double or triple therapy)Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)Masking Description: Study participants, care providers. Investigators and outcomes assessor will be masked to the study intervention until the final participant complete the 24-week efficacy assessment.Primary Purpose: Treatment

This is a Phase 3, randomized, double-blind, placebo-controlled, multicenter, parallel-group study in subjects with symptomatic Pulmonary Arterial Hypertension (PAH) 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 defects (CHDs), and currently on background PAH therapy. The primary efficacy endpoint of the study is exercise capacity, as measured by the 6-minute walk distance (6MWD) measured at 24 week following initiation of treatment. Approximately 284 participants will be enrolled and randomized 1:1 to receive either sotatercept or placebo on the background of stable standard-of-care PAH mediation. Study duration will be approximately 2 years A stratified Wilcoxon test will be used for analysis of the primary endpoint, with appropriate imputation for missing data, as detailed in the Statistical Analysis Plan. An unblinded, external, independent Data Monitoring Committee (DMC) will monitor participant safety throughout the course of the study. Participants completing this study will be eligible to receive sotatercept in a separate, open-label extension study.
