A Double-blind, Randomized, Placebo-controlled Study to Evaluate the Impact of Maintaining Hemoglobin Using Eprex (Epoetin Alfa) in Metastatic Breast Carcinoma Subjects Receiving Chemotherapy

Cancer patients often experience anemia due to the disease itself, chemotherapy or both.
Quality of life is also affected, due in part to the fatigue associated with anemia.
Previous studies with epoetin alfa have suggested that achieving a higher hemoglobin level
may improve quality of life and help patients live longer.This randomized, double-blind,
placebo-controlled multi-center study evaluated the effects of treatment with epoetin alfa
in maintaining hemoglobin levels between 12 and 14 g/dL to determine its impact on survival
and quality of life, in addition to investigating the possible role that epoetin alfa may
have on tumor response to chemotherapy. During the double-blind portion of the study,
patients were to receive 12 months of treatment with epoetin alfa or placebo. Thereafter,
follow-up evaluations were to occur every 3 months until 75% of the patients had died.
Effectiveness was to be determined by recording the number of patients surviving at 12
months, the change in hemoglobin from the start of the study until study completion,
response to chemotherapy and quality of life. Safety evaluations (incidence of adverse
events, physical examinations and clinical laboratory tests) were to be performed throughout
the study. The study hypothesis was that maintaining hemoglobin in the range of 12 to 14
g/dL would improve 12-month survival and quality of life in patients with metastatic breast
cancer who were receiving chemotherapy. Since the time this study was originally designed,
the prescribing information for epoetin alfa has changed. Current use of epoetin alfa should
follow the prescribing information. Patients were to receive epoetin alfa injections (40,000
units) under their skin once per week for 12 months or matching placebo. Dosage was to be
adjusted up (to 60,000 units) or down (to 75% of the last dose administered) as needed to
maintain hemoglobin levels between 12 and 14 g/dL.
