研究概览
简要总结
Erythropoietin (EPO) is a hormone produced in the kidney. Its function is to stimulate the production of red cells in the bone marrow. The purpose of this research study is to demonstrate that the administration EPO to critically ill subjects in the intensive care unit (ICU) reduces the number of patients requiring red blood cell (RBC) transfusion as compared with placebo (a liquid without active medicine).
详细描述
In this study the amount of drug and frequency of dosing is under investigation. Erythropoietin (EPO) will be given by subcutaneous injection (a small needle prick placed underneath the skin). The maximum number of injections a patient may receive is 3. The total expected length of time of patient participation in the study is about 140 days (about 5months).
This study consists of a screening period, treatment period and post treatment period. The study doctor will determine whether the patient is suitable for the study. Safety evaluations will be performed at specified intervals throughout the study and will consist of laboratory tests, vital signs (such as blood pressure), physical examinations and the occurrence and severity of adverse events as well as other study specific procedures.
Eligible patients will be assigned by chance (like flipping a coin) to one of two treatment groups; 40,000 units of EPO or Placebo. Unless the need arises, neither the patient nor the study staff, will know which treatment the patient receives.
The patient will receive an injection of study drug on Study Days 1, 8 and 15 as long as they remain in the same hospital and their hemoglobin (Hb) level is less than 12g/dL. If the patient's hemoglobin level is greater than 12g/dL on any scheduled medication day, study medication will not be given. However the patient will remain in the study and a re-assessment will be done at the next dosing time point. The patient will also receive iron therapy (at least 150 mg) from Study Day 1 (if tolerated) through Study Day 29 or until the patient is discharge from the hospital or withdraws from the study (whichever comes first).
Treatment with study drug will be stopped if the patient become pregnant, or the study doctor feels that it is in the patient's best interest. If treatment is stopped before Study Day 15, the patient will be required to return for scheduled study assessments through Study Day 140.
