Rationale: Ixmyelocel-T is associated with a wide range of biological activities relevant to tissue repair and regeneration. Objective: To evaluate the safety and efficacy of ixmyelocel-T in 2 prospective randomized phase 2A Trials administered via minithoracotomy or intramyocardial catheter injections in patients with dilated cardiomyopathy (DCM) stratified by ischemic or nonischemic status. Methods and Results: In IMPACT-DCM, patients were randomized to either ixmyelocel-T or standard-ofcare control in a 3:1 ratio (n=39); ixmyelocel-T was administered intramyocardially via minithoracotomy. In Catheter-DCM, patients were randomized to either ixmyelocel-T or standard of care control in a 2:1 ratio (n=22); ixmyelocel-T was administered intramyocardially using the NOGA Myostar catheter. Only patients randomized to ixmyelocel-T underwent bone marrow aspiration and injections. In the 2 studies, a total of 61 patients were randomized, and 59 were treated or received standard of care. Fewer ischemic patients treated with ixmyelocel-T experienced a major adverse cardiovascular event during follow-up when compared with control patients. A similar benefit was not seen in the nonischemic patients. Heart failure exacerbation was the most common major adverse cardiovascular event. Ixmyelocel-T treatment was associated with improved New York Heart Association class, 6-minute walk distance, and Minnesota Living with Heart Failure Questionnaire scores in the ischemic population relative to control; a similar trend was not observed in the nonischemic population. Conclusions: Intramyocardial injection with ixmyelocel-T reduces major adverse cardiovascular event and improves symptoms in patients with ischemic DCM but not in patients with nonischemic DCM. © 2014 American Heart Association, Inc.
