Catalyst Pharmaceutical Partners Signs Definitive Agreement With the National Institute on Drug Abuse (NIDA) To Conduct U.S. Phase II(B) Clinical Trial for Cocaine Addiction

Published: Apr 13, 2010

CORAL GABLES, Fla., April 13 /PRNewswire-FirstCall/ -- Catalyst Pharmaceutical Partners, Inc. (NasdaqCM: CPRX) announced today that it has signed a definitive Clinical Trial Agreement (CTA) with the National Institute on Drug Abuse (NIDA) to jointly conduct a U.S. Phase II(b) clinical trial evaluating CPP-109, Catalyst's formulation of vigabatrin, for the treatment of cocaine addiction. As part of the CTA, NIDA, under their agreement with Veteran's Administration Cooperative Studies Program, will provide substantial resources for the estimated $10 million trial cost. Catalyst will contribute approximately $2.8 million in resources.

"Currently, there are no FDA-approved medications to battle cocaine addiction," said Dr. David McCann, Associate Director, Division of Pharmacotherapies and Medical Consequences of Drug Abuse, NIDA. "We are involved because we are encouraged by findings from prior animal and human studies that suggest promise for this medication as a treatment for the nation's estimated 2.1 million cocaine abusers."

About Catalyst Pharmaceutical Partners

Catalyst Pharmaceutical Partners, Inc. is a development-stage biopharmaceutical company focused on the development and commercialization of prescription drugs targeting diseases of the central nervous system with a focus on the treatment of drug addiction and epilepsy. Catalyst has two products in development, and is currently evaluating the lead product candidate, CPP-109 (vigabatrin, a GABA aminotransferase inhibitor) for the treatment of cocaine addiction. CPP-109 has been granted "Fast Track" status by the U.S. Food & Drug Administration (FDA) for the treatment of cocaine addiction, which indicates that the FDA has recognized that CPP-109 is intended for the treatment of a serious or life-threatening condition for which there is no effective treatment and which demonstrates the potential to address an unmet medical need. Catalyst also expects to evaluate CPP-109 for the treatment of other addictions and obsessive-compulsive disorders. Catalyst is also in the early stages of developing CPP-115, another GABA aminotransferase inhibitor that could be more potent than vigabatrin but may have reduced side effects (e.g., visual field defects, or VFDs) from those associated with vigabatrin. Catalyst is planning to develop CPP-115 for several indications, including epilepsy and drug addiction. Catalyst believes that it controls all current intellectual property for drugs that have a mechanism of action related to GABA aminotransferase. For more information about the Company, go to
