Increase to \>=140 systolic and increase \> 20 mmHg compared to baseline systolic 4. Increase to \>=90 mmHg diastolic and increase \> 20 mmHg compared to baseline diastolic 5. Introduction of new anti-hypertension medication during treatment 6. Increase in dose of baseline anti-hypertension medication during treatment 7. \>= Grade 2 (moderate severity or worse) hypertension as an adverse event

Groups in this outcome

Sotatercept 0.1 mg/kg

Sotatercept 0.1 mg/kg administered via subcutaneous injection every third week (Q3W). Participants were randomized to either the 0.1 mg/kg arm or the 0.3 mg/kg arm. Efficacy and safety data were assessed by a Steering Committee. Based upon the occurrence of dose-limiting toxicity (DLT) in ≤ 1/5 subjects in Cycle 1 in the 0.1 mg/kg and 0.3 mg/kg treatment groups, the 0.5 mg/kg treatment group began inclusion in the randomization scheme.

Sotatercept 0.3 mg/kg

Sotatercept 0.3 mg/kg administered via subcutaneous injection every third week (Q3W). Participants were randomized to either the 0.1 mg/kg arm or the 0.3 mg/kg arm. Efficacy and safety data were assessed by a Steering Committee. Based upon the occurrence of dose-limiting toxicity (DLT) in ≤ 1/5 subjects in Cycle 1 in the 0.1 mg/kg and 0.3 mg/kg treatment groups, the 0.5 mg/kg treatment group began inclusion in the randomization scheme.

Sotatercept 0.5 mg/kg

Sotatercept 0.5 mg/kg administered via subcutaneous injection every third week (Q3W). Participants were randomized to one of the active treatment arms. Efficacy and safety data were assessed by a Steering Committee. Based upon the occurrence of dose-limiting toxicity (DLT) in ≤ 1/6 subjects in Cycle 1 in the 0.5 mg/kg treatment group, the 1.0 mg/kg treatment group began inclusion in the randomization scheme.

Sotatercept 1.0 mg/kg

Sotatercept 1.0 mg/kg administered via subcutaneous injection every third week (Q3W). Participants were randomized to one of the active treatment arms. Efficacy and safety data were assessed by a Steering Committee. Based upon the occurrence of dose-limiting toxicity (DLT) in ≤ 1/6 subjects in Cycle 1 in the 1.0 mg/kg treatment group, the 2.0 mg/kg treatment group began inclusion in the randomization scheme. Following evaluation of all treatment group data by the Steering Committee, enrollment continued only in the 1.0 mg/kg arm because the arm had the greatest frequency of erythroid hematological improvement (HI-E).

Sotatercept 2.0 mg/kg

Sotatercept 2.0 mg/kg administered via subcutaneous injection every third week (Q3W). Participants were randomized to one of the active treatment arms. Efficacy and safety data were assessed by a Steering Committee. The 2.0 mg/kg sotatercept dose was reduced to 1.5 mg/kg for ongoing and newly enrolled participants by protocol amendment.
