CATALYST PHARMACEUTICALS PARTNERS

Catalyst is a specialty pharmaceutical company focused on the development and commercialization of prescription drugs targeting rare (orphan) neuromuscular and neurological diseases, including Lambert-Eaton Myasthenic Syndrome (LEMS), infantile spasms and Tourette's disorder. Catalyst is developing Firdapse™ (Amifampridine Phosphate, or 3,4-diaminopyridine phosphate) for the treatment of LEMS, a rare neuromuscular, autoimmune disorder frequently associated with small cell lung cancer. Catalyst also believes that Firdapse™ has the potential to treat other neuromuscular disorders such as congenital myasthenic syndrome and some cases of myasthenia gravis that are refractory to currently approved therapies.
