Law Offices of Howard G. Smith announces that it is investigating potential claims on behalf of purchasers of the securities of Catalyst Pharmaceutical Partners, Inc. ("Catalyst" or the "Company") (NASDAQ:CPRX) concerning possible violations of federal securities laws. The investigation focuses on allegations that certain statements issued by the Company between October 31, 2012 and October 18, 2013, concerning Catalyst's business and financial prospects were materially false and/or misleading.

Catalyst operates as a development-stage specialty pharmaceutical company, focused on the development and commercialization of novel prescription drugs targeting rare neuromuscular and neurological diseases and disorders. One of the Company's principal products is Firdapse, currently in Phase III clinical trials for treatment of Lambert-Eaton Myasthenic Syndrome (LEMS), a rare and sometimes fatal autoimmune disease characterized by muscle weakness.

The investigation is related to allegations that one of Catalyst's competitors - a private pharmaceutical company - has been manufacturing a drug biologically equivalent to Firdapse, and providing it to patients with LEMS, free of charge, through a compassionate use program. On October 18, 2013, an article published by The Street stated that Catalyst's Firdapse was the same drug that its competitor has been manufacturing and providing in the U.S. for the past 20 years.

If you purchased Catalyst shares, if you have information or would like to learn more about these claims, or if you have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Howard G.
