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).
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)
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.

Participants must meet the following criteria to be enrolled in this proof-of-concept study:
- Age 18 to 85 years
Clinical diagnosis of HFpEF:
• Left ventricular ejection fraction ≥50%, with no history of LVEF below 45% in more than two consecutive measurements
- Demonstrated Cpc-PH by all of the following:
- Baseline RHC performed within 28 days of or at Visit 1 (during the Screening Period) documenting a minimum PVR of ≥320 dyn•sec/cm5 (4 wood units)

- Chronic medication for HF or for any underlying condition, administered at a stable (per investigator) dose for ≥30 days prior to Visit 1. 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.

- Have 2 negative urine or serum pregnancy tests as verified by the investigator prior to starting study drug administration; must agree to ongoing pregnancy testing during the course of the study and until 8 weeks after the last dose of the study drug
- If sexually active with a male partner: use highly effective contraception without interruption for at least 28 days prior to starting the investigational product AND agree to use the same highly effective contraception in combination with a barrier method during the study (including dose interruptions), and for 16 weeks (112 days) after discontinuation of study drug
- 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
- 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
- Ability to understand and provide documented consent for participation
