NEW YORK, Oct. 10, 2012 (GLOBE NEWSWIRE) -- NeoStem, Inc. (NYSE:NBS), an emerging leader in the fast growing cell therapy market, announced today that a new article published by the International Scholarly Research Network provides further evidence that AMR-001, NeoStem's lead product candidate through its Amorcyte subsidiary, appears capable of preserving heart muscle function following a large myocardial infarction. Amorcyte demonstrated in its Phase 1 trial that AMR-001 preserved heart muscle function when a therapeutic dose of cells was administered. No patient experienced a deterioration in heart muscle function who received 10 million cells or more whereas 30 to 40 percent of patients not receiving a therapeutic dose did. The new study shows that cardiac muscle function sparing effects are evident even earlier after treatment than previously shown.
The article titled " Assessment of myocardial contractile function using global and segmental circumferential strain following intracoronary stem cell infusion after myocardial infarction: MRI Feature Tracking Feasibility Study" by Sabha Bhatti, MD, et al. appears in ISRN Radiology Volume 2013, Article ID 371028 and is published online at http://www.isrn.com/journals/radiology/2013/371028 . The publication by Dr. Bhatti and colleagues, including Dr. Andrew Pecora, Chief Medical Officer of NeoStem, supports the finding that AMR-001 preserves heart function. Previously, Amorcyte, a NeoStem subsidiary, showed that six months after STEMI AMR-001 improved blood flow to the heart and preserved heart muscle. By using cardiac magnetic resonance imaging, specifically measuring circumferential strain of the left ventricle, the authors show that AMR-001's effects are evident by three months after STEMI.
AMR-001's angiogenic and anti-apoptotic mechanisms of action indicate that preservation of heart muscle function should start within weeks and be evident in fewer than 6 months. This publication, based on blinded analysis of Amorcyte's Phase 1 data, confirms the expected time course for AMR-001's mechanism of action. In the context of previously published results, these effects are durable.
