About CPP-115

CPP-115 is a novel GABA aminotransferase inhibitor and vigabatrin analogue that, based on preclinical studies to-date, is greater than 100 times more potent than vigabatrin and may have reduced side effects (e.g., visual field defects, or VFDs and sedation) from those associated with vigabatrin. Catalyst licensed CPP-115 from Northwestern University where it was invented by Dr. Richard B. Silverman, the John Evans Professor of Chemistry, and a team of scientists. Dr. Silverman holds more than 40 patents and is the inventor of Pfizer's drug, pregabalin (Lyrica®). CPP-115 has been granted Orphan Drug Designation for the treatment of infantile spasms by the U.S. Food & Drug Administration (FDA), and has been granted Orphan Medicinal Product Designation for the treatment of West Syndrome by the European Commission. It has also been granted Fast Track status by the FDA for the treatment of cocaine addiction. CPP-115 has successfully completed its initial Phase I(a), first-in-man, single ascending dose safety and tolerance study. Catalyst is planning to develop CPP-115 for several indications, including addiction, epilepsy and other CNS indications.
