Catalyst Pharmaceutical Partners Reports Fourth Quarter and Year-End 2008 Financial Results

CORAL GABLES, Fla., March 27 /PRNewswire-FirstCall/ -- Catalyst Pharmaceutical Partners, Inc. , a biopharmaceutical company that acquires, in-licenses, develops and commercializes prescription drugs for the treatment of drug addiction, today reported financial results for the fourth quarter and year ended December 31, 2008.

"Catalyst made significant progress in 2008," said Patrick J. McEnany, Chief Executive Officer of Catalyst Pharmaceutical Partners. "During the year, we initiated two U.S. multi-center, Phase II, double-blind, placebo-controlled trials evaluating CPP-109 as a potential treatment for cocaine and methamphetamine addiction. In September we executed a successful equity financing for $4.5 million just prior to the deterioration of the capital markets and the economy. This equity raise, combined with the recently announced change in our clinical development program, provides Catalyst with sufficient working capital through 2010. Furthermore, once we report initial top-line results for our U.S. Phase II cocaine trial, our strengthened balance sheet should allow us to engage potential corporate partners and explore a variety of transactions on terms that may prove to be more favorable to our shareholders. Concurrently, we are actively pursuing government funding from agencies that operate under the National Institutes of Health umbrella to further our development plans for large-scale clinical trials using CPP-109 to treat cocaine and methamphetamine addiction, as well as pilot studies for other addictions, such as alcohol and nicotine abuse, and obsessive-compulsive disorders, including binge eating."

Clinical Development Update

In January 2008, Catalyst initiated enrollment of subjects for its U.S. Phase II clinical trial evaluating the use of CPP-109 for the treatment of cocaine addiction. The Phase II trial is designed as a randomized, double-blind, placebo-controlled, intent-to-treat, multi-center trial to evaluate the safety and efficacy of CPP-109 as a treatment for cocaine addiction. Under the trial protocol, subjects will be treated for a period of 12 weeks, with an additional 12 weeks of follow-up. The primary objective of the trial is to demonstrate that a larger proportion of CPP-109-treated subjects than placebo-treated subjects are cocaine-free during their last two weeks of treatment (weeks 11 and 12). Additionally, Catalyst will be measuring a number of secondary endpoints based on reductions of cocaine use and craving. In January 2009, Catalyst completed enrollment for this trial, having enrolled 186 subjects at 11 addiction centers around the United States. Initial top-line results for the cocaine trial are expected at the end of the second quarter of 2009.

In June 2008, Catalyst initiated enrollment of subjects for its randomized, double-blind, placebo-controlled U.S. Phase II clinical trial evaluating CPP-109 for the treatment of methamphetamine addiction using a trial protocol that is almost identical to the cocaine trial. On March 3, 2009, in order to conserve cash and to focus its development efforts on evaluating CPP-109 for the treatment of cocaine addiction, Catalyst announced that it had halted enrollment in the methamphetamine trial. Instead, the methamphetamine trial has been converted into a smaller proof-of-concept study with the 57 subjects who had already been enrolled. Initial results for the methamphetamine proof-of-concept study are expected in the third quarter of 2009.
