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)

Recruiting

This Phase 2, double-blind, randomized, placebo-controlled, interventional study is designed to evaluate the efficacy, measured by change from baseline in PVR (primary endpoint) and 6MWD (key secondary endpoint) of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. Safety: The safety and tolerability of sotatercept versus placebo in adults with Cpc-PH due to HFpEF will be assessed by the secondary endpoints.

Diuretics and/or anticoagulants are excepted from this rule but should not be newly started or stopped within 30 days of Visit 1, and a prescribed dose change should not occur within 7 days of Visit 1. Anticoagulation may be suspended for RHC if necessary.

• Refrain from breastfeeding a child or donating blood, eggs, or ovum for the duration of the study and for at least 16 weeks (112 days) after the last dose of study drug See Appendix 2 for additional contraceptive information.
• Male participants must:
• Agree to use a condom, defined as a male latex condom or non latex condom NOT made out of natural (animal) membrane (e.g., polyurethane), during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions, and for at least 16 weeks (112 days) following investigational product discontinuation, even if he has undergone a successful vasectomy
• Refrain from donating blood or sperm for the duration of the study and for 16 weeks (112 days) after the last dose of study drug
• Ability to adhere to the study visit schedule and understand and comply with all protocol requirements
• Agreement to not participate in any other trials of investigational drugs/devices while enrolled in the A011-16 study
