Stem Cell Study for Patients With Heart Disease

Status Completed

Clinical Trial Summary

The purpose of this study is to determine if cell therapy with your own cells (autologous cells) delivered with a catheter to regions of the heart with poor blood flow will be safe and if it will relieve your chest pain and/or your ability to exercise.

Clinical Trial Description

The goal of this study is to determine the safety of various doses of autologous (one's own) stem cells, delivered with a catheter into the regions of the heart with poor blood flow. Stem cells are primitive cells produced by bone marrow that can develop into blood cells or other types of cells. In addition to determining whether this new approach is safe, the diagnostic tests may offer preliminary insights into the usefulness of this approach for treating myocardial ischemia (the condition where areas in the heart are lacking enough oxygen and blood flow to keep the heart muscle working well).

This is a blinded, randomized study to compare a certain type of stem cell called CD34-positive versus a placebo agent (normal saline). You will have a 3:1 chance of receiving your CD34-positive stem cells versus the placebo agent (normal saline). You will not know whether you received the CD34-positive cells or the placebo agent (normal saline). If you are randomized to receive placebo (normal saline), you will undergo all of the pre-treatment phases of this study (including the stem cell mobilization phase and the apheresis procedure), but rather than receiving injections of CD34-positive cells, you will receive injections of the placebo agent (normal saline). There is some research evidence that suggests CD34-positive cells may help develop new blood vessels or improve blood flow when injected directly into the heart muscle. ;
