A Study to Evaluate the Safety and Effectiveness of Epoetin Alfa Versus Placebo in Patients With Persistent Anemia as a Result of Cancer Treatment With Cisplatin, a Platinum-containing Chemotherapy Drug

Overview

The purpose of this study is to evaluate the safety and effectiveness of epoetin alfa versus placebo in the treatment of persistent anemia caused by advanced cancer and aggressive cisplatin chemotherapy. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.

Patients undergoing treatment with cisplatin-containing chemotherapy frequently develop significant anemia (hemoglobin \<= 10.5 grams/deciliter). Agents that can increase the amount of hemoglobin in cancer patients undergoing treatment with cisplatin-containing cyclic chemotherapy may improve the patients' reduced physical strength and reduced stamina resulting from anemia, increase the patients' ability to continue chemotherapy, and improve the patients' overall qualify of life. Epoetin alfa is a genetically engineered form of a natural hormone (erythropoietin) that is used to treat anemia by stimulating red blood cell production. This is a randomized, double-blind, placebo-controlled, parallel group, multicenter study. This study evaluates the safety and effectiveness of epoetin alfa in treating patients who develop persistent anemia as a result of treatment with aggressive cisplatin-containing cyclic chemotherapy (every 3 to 4 weeks) for any cancer type (except rapid and severe onset of leukemias and malignancies of the bone marrow and spleen). The study consists of a \<= 7 day screening period when patients' eligibility is determined, a 12-week double-blind treatment period, and an optional open-label treatment period. Eligible patients will be randomly assigned to one of two treatment groups: epoetin alfa 150 units/kilogram or a comparable volume of placebo, given by injection beneath the skin. Patients will be treated with study medication 3 times weekly for 12 weeks. Two of the 3 weekly doses of study medication may be self-administered by the patient at home; the patient is visited by a health professional at least once weekly to administer the other dose(s). The dose of study medication may be increased or decreased at the discretion of the physician, based on the results of blood tests. Depending on the patient's chemotherapy cycle, he or she will return to the study site every 3 or 4 weeks for administration of study medication. During the open-label treatment period, patients who choose to continue will receive 3 injections per week of epoetin alfa under the skin, until the completion of his or her chemotherapy treatments. Safety evaluations, including laboratory tests, vital signs, reporting of adverse events, physical examination, and electrocardiograms, are performed throughout the study. Effectiveness of the study drug will be determined by the number of transfusions patients require and by changes in blood test results (hemoglobin, hematocrit, and immature red blood cells) from before the start of the study to the end of the study. The study hypothesis is that epoetin alfa will, more effectively than placebo, stimulate adequate production of red blood cells to elevate the hemoglobin level in cancer patients who are anemic as a result of undergoing treatment with aggressive cisplatin-containing cyclic chemotherapy. Double-blind: Epoetin alfa 150 units/kilogram, or matching volume of placebo, injected beneath the skin 3 times weekly for 12 weeks. Open-label: Epoetin alfa at the dose received at the end of the double-blind study injected beneath the skin 3 times weekly for any remaining cycles of chemotherapy.
