NeoStem Reports Data Safety Monitoring Board Recommends Continuation of PreSERVE AMI Phase 2 Trial

NEW YORK, Aug. 15, 2012 (GLOBE NEWSWIRE) -- Amorcyte, a company of NeoStem, Inc. (NYSE MKT:NBS) ("NeoStem" or the "Company"), a rapidly emerging market leader in the fast growing cell therapy market, today announced that it received on August 9, 2012 approval to continue its PreSERVE AMI Phase 2 clinical trial following its first interim data and safety review by the Data Safety Monitoring Board (DSMB). The PreSERVE trial is a Phase 2, randomized, placebo controlled, double-blind study expected to include 160 patients at more than 40 clinical sites. The trial's product candidate, AMR-001, is designed to prevent major adverse cardiac events following acute myocardial infarction (AMI). Patient enrollment for the PreSERVE trial began in January 2012 and the Company anticipates completing enrollment in 2013 with six months initial data readout near the end of 2013.

"We are pleased that, similar to our Phase 1 trial, the first external review of our Phase 2 trial data confirms that there are no safety signals that would preclude the trial from continuing as planned," said Andrew L. Pecora, M.D. FACP CPE, Chief Medical Officer of NeoStem. "The PreSERVE AMI study to date indicates that multiple National Study sites are capable of acquiring the necessary volume of bone marrow to create the AMR-001 product five to seven days after an AMI in a safe and practical manner, and once created the product can be delivered and administered without a safety signal."

NeoStem management believes that cell therapy is a disruptive technology in the $50 billion worldwide regenerative medicine market. Many key opinion leaders in the scientific, medical and investment communities consider AMR-001 to be best in class. Peak annual worldwide sales of AMR-001 for this indication could exceed $1 billion based upon a conservative market penetration of its qualified target patient population. AMR-001 is protected by two issued and multiple pending U.S. patents with corresponding patent coverage in selected markets around the world. The Amorcyte AMR-001 product development program also extends to congestive heart failure (CHF). The Company is preparing to launch its CHF Phase 1 clinical trials in early 2013. The worldwide CHF patient population is estimated to be four times larger than that of AMI.

About NeoStem, Inc.

NeoStem, Inc. ("we," "NeoStem" or the "Company") continues to develop and build on its core capabilities in cell therapy to capitalize on the paradigm shift that we see occurring in medicine. In particular, we anticipate that cell therapy will have a large role in the fight against chronic disease and in lessening the economic burden that these diseases pose to modern society. Our January 2011 acquisition of Progenitor Cell Therapy, LLC ("PCT") provides NeoStem with a foundation in both manufacturing and regulatory affairs expertise. We believe this expertise, coupled with our existing research capabilities and collaborations, will allow us to achieve our mission of becoming a premier cell therapy company. Our PCT subsidiary's manufacturing base is one of the few current Good Manufacturing Practices ("cGMP") facilities available for contracting in the burgeoning cell therapy industry. Amorcyte, LLC ("Amorcyte"), which we acquired in October 2011, is developing a cell therapy for the treatment of cardiovascular disease. Amorcyte's lead compound, AMR-001, represents NeoStem's most clinically advanced therapeutic and Amorcyte is enrolling patients for a Phase 2 trial to investigate AMR-001's efficacy in preserving heart function after a heart attack. We also expect to begin a Phase 1 clinical trial in 2013 to investigate AMR-001's utility in arresting the progression of congestive heart failure and the associated comorbidities of that disease. Athelos Corporation ("Athelos"), which is approximately 80%-owned by our subsidiary, PCT, is engaged in collaboration with Becton-Dickinson that is exploring the earlier stage clinical development of a T-cell therapy for autoimmune conditions. In addition, our pre-clinical assets include our VSELTM Technology platform as well as our MSC (mesenchymal stem cells) product candidate for regenerative medicine.
