Study Summary

This is a Phase 2, double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. The objective of this study is to evaluate the efficacy, safety and tolerability of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. Efficacy is measured by change from baseline in pulmonary vascular resistance (PVR, primary endpoint) and 6-minute walk distance (6MWD, key secondary endpoint).

Primary Outcome

PVR, a hemodynamic variable of pulmonary circulation, is measured by right heart catheterization (RHC).
