NCT00931606

Brief Summary

The purpose of this study is to evaluate the percentage of participants in each sotatercept dose regimen who achieve a hematopoietic response during the treatment period including up to 2 months after the last dose of sotatercept treatment of chemotherapy-induced anemia (CIA) in participants with metastatic breast cancer. Hematopoietic response was defined as an increase in hemoglobin concentration of ≥ 1 g/dL relative to baseline for 28 consecutive days during the treatment period including up to 2 months after the last dose of sotatercept in the absence of red blood cell (RBC) transfusion or treatment with an erythropoiesis-stimulating agent (ESA).

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants Who Achieved a Hematopoietic Response

    Hematopoietic response rate is defined as the percentage of participants who had increase in hemoglobin concentration of ≥ 1 g/dL relative to baseline for 28 consecutive days during the treatment period including up to 2 months after the last dose of study treatment in the absence of red blood cell (RBC) transfusion or treatment with an erythropoiesis-stimulating agent (ESA). The percentage of participants who achieved hematopoietic response is presented.

    Baseline and Up to ~145 Days

Secondary Outcomes (21)

  • Number of Participants Who Experienced an Adverse Event (AE)

    Up to ~175 Days

  • Number of Participants Who Discontinued Study Intervention Due to an Adverse Event

    Up to ~85 Days

  • Percentage of Participants Achieving an Increase From Baseline Hemoglobin of ≥ 2 g/dL

    Baseline and Up to ~145 Days

  • Percentage of Participants Achieving an Increase From Baseline Hemoglobin ≥ 11 g/dL

    Baseline and Up to ~145 Days

  • Percentage of Participants Achieving an Increase From Baseline Hemoglobin of ≥2 g/dL and/or Hemoglobin ≥ 11 g/dL

Limitations and Caveats

This is an acquired study. No restrictions were imposed on time on current chemotherapy prior to study entry, therefore PFS could have gone beyond the study duration. The time from start of current chemotherapy could have occurred prior to study start and collected as prior anticancer therapy, therefore the upper limit of the confidence interval in the "Sotatercept 0.5 mg/kg" arm, "1791.0 days", didn't exceed the timeframe of 281 days after study start.
