Summary

The goal of REMEDIUM project is to develop personalized stem cell therapy for patients with chronic heart failure due to dilated cardiomyopathy (DCM). The main focus of the project is (1) on repetitive administration of cell therapy that would allow for long-lasting improvements in heart function and outcome in this patient population. In parallel, the investigators aim to (2) develop a standardized patient-specific stem cell product that could be cryopreserved and stored in a stem cell bank for prolonged time periods, and used for therapeutic application when clinically indicated. By using a unique multimodality imaging platform, the goal of this project is also to (3) define standardized clinical criteria that would serve as a guideline for evaluation of the effects of stem cell therapy in future clinical trials and everyday clinical settings. Finally, to improve the clinical implementation of cell therapy,the investigators aim to (4) develop a stem cell delivery technique that could be used to treat both left and right and ventricular failure and could be implemented in a standardized fashion designed for a widespread clinical use.

Conditions

Interventions

BIOLOGICAL

Stem cell therapy

Bone marrow cells will be mobilized into peripheral blood by daily subcutaneous injections of G-CSF (10 µg/kg daily) and collected by leukapheresis. Positive immunomagnetic selection of CD34+ cells will be performed. Electroanatomic mapping of the left ventricle will be performed using the Biosense NOGA system (Biosense-Webster®, Diamond Bar, CA). The target area for cell delivery will be defined as the myocardial segments with unipolar voltage potentials ≥8.3 mV, bipolar amplitudes \>1.9 mV, and linear shortening \<6%. Intramyocardial delivery of cell suspension will be performed with the MyoStar (BiosenseWebster®, Diamond Bar, CA) injection catheter. Each patient will receive 20 injections (0.3 mL each; total volume of 6 mL). All the procedures will be repeated 6 months after baseline.
