For safety monitoring, all patients will be followed for adverse events, hemoglobin (Hb), hematocrit (Hct), blood chemistries and blood pressure measurements throughout the study. All eligible patients with hemoglobin < 12.0 g/dL will be randomized to receive Epoetin alfa injections (120,000 Units ) under the skin every 3 weeks for a maximum of 16 treatment weeks. Doses may be adjusted depending on the patients hemoglobin levels.
