Erythroid Hematological Improvement (HI-E) [ Time Frame: Up to 24 weeks ]
HI-E (for subjects that require a transfusion of <4 units of RBCs) is an increase ≥1.5 g/dL Hgb sustained over a period ≥8 weeks in the absence of RBC transfusion; or HI-E (for subjects that require a transfusion of ≥4 units of RBCs) is a decrease ≥4 units of RBCs transfused over a period of 8 weeks

Study of Sotatercept for the Treatment of Anemia in low-or Intermediate-1 Risk Myelodysplastic Syndromes (MDS) or Non-proliferative Chronic Myelomonocytic Leukemia (CMML)
An Open-label, Randomized, Phase 2, Parallel, Dose-Ranging, Multicenter Study of Sotatercept for the Treatment of Patients With Anemia and Low or Intermediate-1 Risk Myelodysplastic Syndromes or Non-proliferative Chronic Myelomonocytic Leukemia (CMML)
The primary objective of this study is to determine a safe, tolerable and effective dose of sotatercept that results in the greatest frequency of improvement of anemia in patients diagnosed with low- or intermediate-1 risk MDS or non-proliferative chronic myelomonocytic leukemia (CMML).
Following enrollment of the initial 3 arms; additional cohorts of 20 patients for intermediate cohorts (not to exceed 2.0 mg/kg) may be added at the time of dose escalation up to 1.0 mg/kg and up to 2.0 mg/kg (eg, 0.75 mg/kg or 1.5 mg/kg respectively) based on assessment by the Steering Committee of available safety and efficacy data when at least six subjects have at least three cycles of treatment in the current dose level.
