A Study to Evaluate the Effectiveness and Safety of Epoetin Alfa During the Period When One is Donating One's Own Blood Before Surgery. - Full Text View

ClinicalTrials.gov Identifier:	NCT00270179

Purpose

The purpose of this study is to evaluate the whether epoetin alfa stimulates the bone marrow to produce red blood cells and therefore increases a patient's ability to self-donate blood prior to major surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.

Primary Outcome Measures:

Units of blood that can be obtained per patient; Change from pre-study to post-study in hemoglobin and hematocrit; Transfusions required around the time of surgery

Secondary Outcome Measures:

Safety (clinical laboratory tests, vital signs, incidence and severity of any adverse or unusual experiences associated with drug administration)

Estimated Enrollment:	154
Estimated Study Completion Date:	May 1988

Detailed Description:

Major surgical procedures may require several units of blood. Blood transfusions from other people may be associated with transfusion reactions that cause fever or uncommonly, blood-borne infections. However, self-blood collections may cause anemia in a patient who will be undergoing surgery a few weeks later. Previous research with epoetin alfa suggests that it increases the rate of red blood cell production and has a beneficial effect on anemia. This randomized, double-blind, placebo-controlled 21-day study is designed to determine whether intravenous epoetin alfa will stimulate a patient'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 disease. Patients will be randomly assigned to receive either epoetin alfa 600 units per kilogram of body weight or a matching volume of placebo injected into a vein on the first study day and every 3 to 4 days thereafter for 21 days, for a total of 6 doses. The primary measures of effectiveness will be determined by the number of units of blood that can be obtained from patients during the study, the change in hemoglobin and hematocrit from pre-study to post-study, and the number of transfusions required around the time of surgery. Safety will be evaluated based on laboratory tests, vital signs, and the incidence and severity of any adverse or unusual experiences associated with drug administration. The study hypothesis is that patients treated with epoetin alfa will be able to donate more units of blood for their own surgery while receiving epoetin alfa than patients receiving placebo.

Epoetin alfa 600 units per kilogram or an equal volume of placebo injected into a vein on the first day of the study, and every 3 to 4 days thereafter until day 21, for a total of 6 doses.
