About this study
Official title: A Double-Blind, Placebo-Controlled Study to Determine Whether R-HuEPO Can Facilitate Presurgical Autologous Blood Donation in Patients With Low Hematocrit Levels
The purpose of this study is to evaluate the safety of epoetin alfa and its effectiveness in facilitating the presurgical collection of blood from anemic patients for possible self-transfusion during and after scheduled joint surgery and its effectiveness in reducing surgery-related transfusion requirements. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
Read the 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 infections such as hepatitis or AIDS that are 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 increases the rate of red blood cell production and decreases anemia. This randomized, double-blind, placebo-controlled, multicenter study is designed to determine whether epoetin alfa in patients with low hematocrit (red blood cell percentage <39 percent) will stimulate the 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 either 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 self-donated blood collected, the number of units of donor blood used at the time of surgery, and the red blood cell percentages just before surgery. 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 during the 3 weeks prior to surgery, will need fewer donor-donated units of blood, and will have a higher level of red blood cells than patients who receive placebo. 600 units of epoetin alfa per kilogram of body weight, or an equivalent volume of placebo, injected into a vein every 3 to 4 days for 21 days (6 doses) during the period before surgery.

A Phase 3 study testing epoetin alfa in people with Anemia, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 May 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of units of blood self-donated; Number of donor-donated units of blood used; Total red blood cell volume; Total red blood cell production; Change in hemoglobin from baseline to after the final dose of study medication, but before surgery. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2011.
