Clinical Trial Summary

The objective of this study is to evaluate the effects of sotatercept (MK-7962, formerly called ACE-011) treatment (plus background pulmonary arterial hypertension (PAH) therapy) versus placebo (plus background PAH therapy) on time to clinical worsening (TTCW) in participants who are newly diagnosed with PAH and are at intermediate or high risk of disease progression.


Clinical Trial Description

This is a phase 3, randomized, double-blind, placebo-controlled study to evaluate sotatercept when added to background PAH therapy in newly diagnosed intermediate- or high risk PAH participants. Participants enrolled in the study will have a diagnosis within 12 months of study screening of symptomatic PAH (World Health Organization (WHO) Group 1, classified as functional class (FC) II or III) and presentation of idiopathic or heritable PAH, PAH associated with connective tissue diseases (CTD), drug- or toxin- induced PAH, post shunt correction PAH, or PAH presenting at least 1 year following the correction of congenital heart defects. ;
