About

RATIONALE: Epoetin alfa and epoetin beta may cause the body to make more red blood cells. Red blood cells contain iron that is needed to carry oxygen to the tissues. It is not yet known whether epoetin alfa or epoetin beta are more effective when given with or without iron infusion in treating anemia in patients with cancer.

PURPOSE: This randomized phase III trial is studying epoetin alfa or epoetin beta to compare how well they work with or without iron infusion in treating anemia in patients with cancer.

Full description

OBJECTIVES:

• Compare the efficacy of recombinant epoetin alfa or epoetin beta with vs without parenteral iron in anemic, iron-replete patients with nonmyeloid malignancies.

OUTLINE: This is a randomized, controlled, open-label, prospective study. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive recombinant erythropoietic stimulatory activity (ESA) therapy comprising epoetin alfa or epoetin beta subcutaneously (SC) on day 1.
• Arm II: Patients receive ESA therapy as in arm I and parenteral iron (i.e., low molecular weight iron dextran complex IV over 5-10 minutes or iron sucrose injection IV over 10-30 minutes) on day 1.

In both arms, treatment repeats weekly for up to 10 weeks or until hemoglobin reaches 13 g/dL, whichever comes first.

Enrollment: 80 estimated patients

Sex: All

Ages: 16+ years old

Volunteers: No Healthy Volunteers
