Summary

The present investigation will be a Phase II, single center, placebo-controlled, randomized, dose escalation, infusion modality (intracoronary vs transendocardial injection using the Cordis Biosense NOGASTAR TM Mapping Catheter with the Biosense MYOSTAR TM left ventricular injection catheter) transplantation of an autologous (your own stem cells) combination of bone marrow-derived stem cells into myocardium for the treatment of severe coronary ischemia.

The purpose of this research study is to determine if the infusion of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in patients with symptomatic severe coronary ischemia(CI).

In this trial we will determine whether the combination stem cell treatment is safe, feasible and results in the development of mature stable and/or collateral vessels and improvement of cardiac function.

Coronary Ischemia (CI) is intractable angina due to severe coronary artery disease which can seriously decrease blood flow to the heart.

CI needs a comprehensive treatment since the condition will not improve on its own. The overall goal of the treatment is to increase blood flow to the heart and improve symptoms of angina.

The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the heart.

Patients eligible to participate in this study are those suffering from severe blockages of the vessels of the heart and are not candidates for percutaneous revascularization or surgical procedures.

BIOLOGICAL

MESENDO

For the cell product, proper aliquots of each cell type will be taken to fulfill the doses established for this protocol. The two aliquots will be mixed and resuspended to a final volume of 3 ml in the 'Final Suspension Medium' which consists of Dulbecco's Phosphate Buffered Saline (DPBS), containing 5% human serum albumin.

OTHER

placebo

For placebo, 3 ml of the 'Final Suspension Medium' which consists of Dulbecco's Phosphate Buffered Saline (DPBS), containing 5% human serum albumin will be transferred to a 5 ml syringe
