SAN DIEGO–(BUSINESS WIRE)–Jan. 29, 2016– ACADIA Pharmaceuticals Inc. (NASDAQ: ACAD), a biopharmaceutical company focused on the development and commercialization of innovative medicines to address unmet medical needs in central nervous system (CNS) disorders, today announced that the Psychopharmacologic Drugs Advisory Committee of the U.S. Food and Drug Administration (FDA) will review data included in ACADIA’s New Drug Application (NDA) for NUPLAZID™ (pimavanserin) for the treatment of psychosis associated with Parkinson’s disease. The Advisory Committee Meeting is scheduled for March 29, 2016.

“Parkinson’s disease psychosis is a debilitating condition for which there are no FDA-approved treatment options available to patients,” said Steve Davis, ACADIA’s President and Chief Executive Officer. “We look forward to discussing our data from the NUPLAZID clinical program with the members of the Committee.”

The Prescription Drug User Fee Act (PDUFA) action date for completion of FDA review of the NUPLAZID NDA is May 1, 2016. The FDA has granted the NUPLAZID NDA Priority Review status and designated NUPLAZID for the treatment of psychosis associated with Parkinson’s disease as a Breakthrough Therapy.
