Primary Outcome Measures:
  • Maximum change in hemoglobin from baseline [ Time Frame: Weeks 3-13 ]

Secondary Outcome Measures:
  • Number (%) of subjects with a hemoglobin response [ Time Frame: Weeks 5, 9, 13, 16 ]
    Defined as an increase in hemoglobin by ≥ 1.0 g/dL from baseline.

  • Number (%) of subjects achieving hemoglobin 11.0 - 13.0 g/dL [ Time Frame: Weeks 5-13 ]
  • Median time to hemoglobin response [ Time Frame: Week 3-13 ]
  • Changes from baseline observations in clinical assessments and clinical laboratory values [ Time Frame: Weeks 1-16 ]
  • Number of subjects with adverse events [ Time Frame: Weeks 1-16 ]
  • Change from baseline in SF-36 and FACT-An scores [ Time Frame: Weeks 1, 9, 13 ]
