A Study of Sotatercept for the Treatment of Cpc-PH Due to HFpEF (MK-7962-007/A011-16) (CADENCE)

A Phase 2, Double-blind, Randomized, Placebo-controlled Study to Evaluate the Effects of Sotatercept Versus Placebo for the Treatment of Combined Postcapillary and Precapillary Pulmonary Hypertension (Cpc-PH) Due to Heart Failure With Preserved Ejection Fraction (HFpEF)

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).

Study Overview

Detailed Description

Participants enrolled in the study will have a diagnosis of Cpc-PH due to HFpEF with New York Heart Association (NYHA) functional class (FC) II or III. Participants will be randomly assigned in a 1:1:1 ratio to 1 of the 3 treatment groups (placebo, 0.3mg/kg sotatercept and 0.7mg/kg sotatercept) during the placebo-controlled Treatment Period. In the extension phase, sotatercept-treated participants will continue on their current dose. Placebo participants will be re-randomized in a 1:1 ratio to one of the two sotatercept treatment groups utilized in the placebo-controlled Treatment Period. Each participant will be enrolled in the study for up to 114 weeks, including a 28-day Screening Period, a 24-week, double-blind, placebo-controlled Treatment Period, an 18-month Extension Period, and an 8-week Follow-up Period.
