Administration of Mesenchymal Stem Cells in Patients With Chronic Ischemic Cardiomyopathy (MESAMI2)

Stem cell therapy is an emerging treatment for cardiovascular disease but the best cell type and delivery method remain to be determined. Pre-clinical studies demonstrated improvement of cardiac function by Mesenchymal stem cells (MSC) therapy in particular by their paracrine and immunosuppressive properties. Investigators initiated the MESAMI program by the bicentric pilot phase and highlighted the safety and feasibility of intramyocardial injections of MSCs from bone marrow in patients with chronic ischemic cardiomyopathy and left ventricular dysfunction, guide by the NOGA-XP system. The MESAMI program continues with the phase 2, multicenter, double-blind, randomized, placebo-controlled trial.The aim of this phase 2 study is to demonstrate a functional improvement, measuring peak VO2, at 3 months between the cell therapy group and the placebo group.
