Adult stem cells to repair hearts damaged by severe coronary artery disease investigated

CHICAGO - Rush University Medical Center is one of the first medical centers in the country, and currently the only site in Illinois, participating in a novel clinical trial to determine if a subjects own stem cells can treat a form of severe coronary artery disease.

The Autologous Cellular Therapy CD34-Chronic Myocardial Ischemia (ACT34-CMI) Trial is the first human, Phase II adult stem cell therapy study in the U.S. designed to investigate the efficacy, tolerability, and safety of blood-derived selected CD34+ stem cells to improve symptoms and clinical outcomes in subjects with chronic myocardial ischemia (CMI), a severe form of coronary artery disease.

"What were hoping is that these stem cells will be able to stimulate the growth of new blood vessels to bring more blood and oxygen to the heart muscle, so that these patients will have a better quality of life and less chest pain," said Dr. Gary Schaer, director of the Rush Cardiac Catheterization Lab and study investigator.

Myocardial ischemia is a serious heart condition that involves narrowing of coronary arteries and results in limited blood flow to the heart. The disease affects hundreds of thousands of new people each year. A person who suffers from chronic myocardial ischemia continues to experience insufficient flow of oxygen-rich blood to the heart despite optimum medical intervention.

The study is a randomized, double-blind, placebo-controlled study that involves adult subjects with severe coronary artery disease who are currently on the maximum medical therapy and who are not suitable candidates for conventional procedures to improve blood flow to the heart such as angioplasty, stents, or coronary artery bypass surgery.

Rush is one of 15 to 20 research sites nationwide participating in the study, which is sponsored by the Cellular Therapies business unit of Baxter Healthcare Corporation. Baxter technology is used to select the subjects own CD34+ stem
