Catalyst Pharmaceutical Partners to continue development of CPP-109 drug

Oct 1 2009

Catalyst Pharmaceutical Partners, Inc. (Nasdaq: CPRX) today announced that the Company will continue to develop CPP-109 (Catalyst's version of vigabatrin) for the treatment of cocaine and methamphetamine addiction. The Company's decision was made after, and based upon, an in-depth review of the results obtained from its 186-patient Phase II clinical trial evaluating the use of CPP-109 for the treatment of cocaine addiction (CPP-01004) and the top-line results obtained from its 57-patient proof-of-concept study evaluating the use of CPP-109 for the treatment of methamphetamine addiction (CPP-02001).

Catalyst's decision to continue the development of the drug for both indications was supported by a panel of experts who recently met and agreed with the Company's conclusion that there was sufficient evidence of safety and efficacy to justify further development of CPP-109, based upon these trial data and previously published studies of vigabatrin to treat addiction.
