Treatment With Aastrom's Ixmyelocel-T Shown to Reduce Incidence of Major Adverse Cardiovascular Events in Patients With Ischemic Dilated Cardiomyopathy

August 22, 2014 at 12:00 AM EDT

ANN ARBOR, Mich., Aug. 22, 2014 (GLOBE NEWSWIRE) -- Aastrom Biosciences, Inc. (Nasdaq:ASTM), the leading developer of patient-specific expanded cellular therapies for the treatment of severe diseases and conditions, today announced that results from the company's Phase 2a clinical studies of ixmyelocel-T for the treatment of advanced heart failure due to ischemic dilated cardiomyopathy (DCM) were published in the peer-reviewed journal Circulation Research. In an article entitled "Safety and Efficacy of Ixmyelocel-T: An Expanded, Autologous Multi-Cellular Therapy, in Dilated Cardiomyopathy," results showed that treatment with ixmyelocel-T reduced the incidence of major adverse cardiovascular events (MACE) in patients with ischemic DCM.

In two separate open-label studies, a total of 61 patients were randomized and 59 were treated or received standard of care. The combined results among ischemic DCM patients demonstrated that patients treated with ixmyelocel-T experienced fewer MACE events during follow up compared to control patients. Heart failure (HF) exacerbation was the most common MACE. Relative to the control patients, ischemic DCM patients treated with ixmyelocel-T also experienced an improvement in symptoms as measured by the New York Heart Association classification system, a six-minute walk test, and the Minnesota Living with Heart Failure Questionnaire. Similar benefits were not observed in the non-ischemic population.

"The publication of results from the two Phase 2a trials in a peer-reviewed journal is further validation that the available evidence supports continued development of ixmyelocel-T as a treatment for patients with ischemic dilated cardiomyopathy. We currently are enrolling a larger, Phase 2b trial and hope to replicate these very promising results. People living with ischemic DCM are often severely compromised and have very limited treatment options available, so these results are especially encouraging," said Dave Recker, M.D., Aastrom's chief medical officer. 

Ixmyelocel-T is a patient-specific, expanded multicellular therapy manufactured from the patient's own bone marrow using Aastrom's proprietary, highly automated, fully closed cell-processing system. This process selectively expands the population of mesenchymal stromal cells and alternatively activated macrophages, which are responsible for production of anti-inflammatory and pro-angiogenic factors known to be important for repair of damaged tissue. 

"Based upon these results, we see great promise in the use of ixmyelocel-T to treat dilated cardiomyopathy and are working aggressively to advance this development program to the final stages of clinical research and regulatory review," Dr. Recker added. "As recently announced, we are on pace to enroll 108 patients by year end in the Phase 2b ixCELL-DCM clinical trial of ixmyelocel-T for the treatment of advanced heart failure due to DCM."
