Prospective Randomized Study of Mesenchymal Stem Cell Therapy in Patients Undergoing Cardiac Surgery (PROMETHEUS)
PROMETHEUS
A Phase I/II, Randomized, Double-Blinded, Placebo-Controlled Study of the Safety and Efficacy of Intramyocardial Injection of Autologous Human Mesenchymal Stem Cells (MSCs) in Patients With Chronic Ischemic Left Ventricular Dysfunction Secondary to Myocardial Infarction (MI) Undergoing Cardiac Surgery for Coronary Artery Bypass Grafting (CABG)

Brief Summary
Heart attacks are a leading cause of death in both men and women in the United States. When a person has a heart attack, blood is unable to reach a certain area of the heart, and if the blood supply is not re-established quickly, that area of the heart can suffer permanent damage. While recovery from a heart attack can be managed through medications and lifestyle changes, these treatments can not reverse the original damage to the heart. Current research is focusing on the development of cell-based therapies using stem cells to repair organs that have been irreversibly damaged by disease. A specific form of stem cells, called adult mesenchymal stem cells (MSCs), has shown promise for heart repair. This study will evaluate the safety and effectiveness of injecting MSCs into the heart to repair and restore heart function in people who have had a heart attack and who are having heart surgery for coronary artery bypass grafting (CABG).

Study Arms (3)
Lower dose mesenchymal stem cell (MSC) injection
EXPERIMENTALParticipants will receive lower dose mesenchymal stem cell injections for a total of 2 x 10\^7 cells
Higher dose MSC injection
EXPERIMENTALParticipants will receive higher dose of mesenchymal stem cell injections for a total of 2 x 10\^8 cells
(3) Placebo
PLACEBO COMPARATORParticipants will receive placebo injections
Interventions
Participants will receive between 10 and 20 intramyocardial injections of 2 million MSCs per 0.25-0.5 cubic centimeter (cc) for a total of 2 x 10\^7 cells. The injections will be administered following completion of CABG surgery.
Participants will receive between 10 and 20 placebo injections that consist of phosphate buffered saline (PBS) and 1% human serum albumin (HSA).
Participants will receive between 10 and 20 intramyocardial injections of 20 million MSCs per 0.25-0.5 cc for a total of 2 x 10\^8 cells. The injections will be administered following completion of CABG surgery.
Eligibility Criteria
You may qualify if:
- Diagnosis of chronic ischemic heart failure caused by a heart attack
