Aastrom to Present Results of Phase 2a Clinical Trial of Ixmyelocel-T in Dilated Cardiomyopathy Patients at SCAI Scientific Sessions

ANN ARBOR, Mich., May 7, 2012 (GLOBE NEWSWIRE) -- Aastrom Biosciences, Inc. (Nasdaq:ASTM), the leading developer of patient-specific, expanded multicellular therapies for the treatment of severe, chronic cardiovascular diseases, today announced that results from the company's Phase 2a clinical trial of ixmyelocel-T in the treatment of dilated cardiomyopathy (DCM) will be presented at the Society for Cardiovascular Angiography and Interventions (SCAI) Scientific Sessions held May 9-12, 2012 in Las Vegas, Nevada. The Aastrom presentation, entitled "Safety and Efficacy of Ixmyelocel-T, An Expanded Patient-Specific Mixed Cell Therapy, in Dilated Cardiomyopathy," will be made on Thursday, May 10, at 12:26 p.m. during the late-breaking clinical trials session. The presentation will be given by Timothy D. Henry, MD, FACC, director of research at the Minneapolis Heart Institute Foundation.

The Phase 2a clinical trial was designed to evaluate the safety and efficacy of intramyocardial delivery of ixmyelocel-T, Aastrom's investigational, patient-specific, multicellular therapy expanded from a patient's own bone marrow. Ixmyelocel-T is comprised of many of the same cell types as those found in the bone marrow and, importantly, expanded populations of CD90+ mesenchymal stromal cells (MSCs) and CD14+auto+ M2 macrophage cells. Ixmyelocel-T provides multiple reparative activities including resolution of chronic inflammation, remodeling of ischemic tissue and promotion of angiogenesis.

In this study, ixmyelocel-T was evaluated in ischemic and non-ischemic DCM patients with class III/IV heart failure as defined by the New York Heart Association and with limited treatment options. The study included 22 patients who were randomized 2 to 1 and followed for 12 months.
