New Independent Data Monitoring Committee Established by Hemispherx to Accelerate Global Drug Development
PHILADELPHIA, May 3, 2010 (GLOBE NEWSWIRE) -- Hemispherx Biopharma, Inc. (NYSE AMEX:HEB) (the "Company") announced today the formation of an Independent Data Monitoring Committee (DMC) which will oversee the Company's various drug development programs. The principal role of an independent DMC is to perform interim analyses of the clinical outcome data and to insure the safety of patients in clinical trials. The DMC also plays a critical role in studies that may use Adaptive Design wherein trial design modifications can be made after patient enrollment has started. Adaptive Design will enable Hemispherx to respond to data collected during the trial which may include dropping a treatment arm, modifying the sample size, etc, to increase statistical probability of reaching the desired therapeutic outcome.

The three members of the DMC are Thomas R. Zimmerman Jr., MD, F.A.A.N., Philip R. Roane, Jr., Ph.D. and Anita F. Das, Ph.D. Dr. Zimmerman will act as chairman. They will be the core members of the DMC and, from time to time, their skills and knowledge may be supplemented by experts who bring knowledge of a given indication, geographic familiarity, etc. to the Committee for particular studies.

Dr. Zimmerman has over 12 years of medical monitoring experience for all phases of clinical trials, including safety reporting and narrative writing for NDA's and is a Clinical Associate Professor of Neurology at Robert Wood Johnson Medical School. Dr. Roane is an Associate Professor and Vice Chairman of the Department of Microbiology at Howard University and has served on numerous scientific review panels for the National Institutes of Health and the Department of Defense. Dr. Das is President and Principal Biostatistician of AxiStat, Inc. She serves on the Data and Safety Monitoring Committee established by the Best Pharmaceuticals for Children Act which seeks to improve pediatric therapeutics.

By having a formal independent DMC, the Company puts in place a cumulative and broad knowledge gained by DMC members over the course of multiple clinical studies in multiple treatment indications thus further accruing to the benefit and safety of patients suffering from serious diseases without adequate present therapies. The Company has in the planning stages a number of studies for Ampligen® , an investigational therapeutic, and Alferon N Injection®, both in the U.S. and abroad, including the recently announced initiative in India with Alferon N Injection® for the treatment of seriously ill patients hospitalized with influenza, scheduled to begin in the upcoming monsoon season.
