The purpose of this study is to evaluate the safety and effectiveness of epoetin alfa at doses of 150, 300, or 600 units per kilogram of body weight versus placebo in facilitating presurgical collection of blood for self-donation during surgery of the knee, hip or spine. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.

Primary Outcome Measures:
  • Number of units of units of blood donated by the patient; Number of units of donor blood transfused during surgery; Total red cell volume and percentage in self-donated blood; Percentage of sub-standard units of blood self-donated

Secondary Outcome Measures:
  • Percentage in each treatment group of patients requiring blood donated by others; Safety evaluations including the incidence of adverse events

Enrollment: 17
Study Start Date: September 1989
Study Completion Date: August 1991
Detailed Description:
Major surgical procedures may require transfusion of several units of blood. Blood transfusions from other people may be associated with transfusion reactions that cause fever or with viral infections that can be carried (and donated) in blood. However, self-donations of blood may cause anemia in a patient who will be undergoing surgery a few weeks later. Previous research with epoetin alfa suggests that epoetin alfa speeds up the rate of red blood cell production and has a beneficial effect on anemia. This randomized, double-blind, placebo-controlled, multicenter study is designed to determine whether treating patients with epoetin alfa will stimulate a person's bone marrow to produce red blood cells and therefore increase a patient's ability to self-donate blood prior to major surgery for joint diseases. Patients will be randomly assigned to receive 150, 300, or 600 units of epoetin alfa per kilogram of body weight, or matching placebo, injected into a vein on the first study day, and every 3 to 4 days thereafter for 21 days. Effectiveness will be determined by the number of units of blood that can be donated by patients during the study, the number of units of non-self-donated blood used during surgery, the total red cell volume of the self-donated blood, the total red cell production, and the percentage of sub-standard units of blood that are self-donated. Safety evaluations including the incidence of adverse events, physical examinations, and clinical laboratory tests will be performed throughout the study. The study hypothesis is that patients treated with epoetin alfa will be able to donate more units of blood than those patients who receive placebo. Epoetin alfa, 150, 300, or 600 units per kilogram of body weight, or placebo, injected into a vein every three to four days for 21 days (6 doses) during the period before surgery.
