Alkermes Provides Update on FDA Review of ARISTADA™ for the Treatment of Schizophrenia

DUBLIN--(BUSINESS WIRE)--Aug. 21, 2015-- Alkermes plc (NASDAQ: ALKS) today announced that the U.S. Food and Drug Administration (FDA) has advised Alkermes that it will not be able to complete its review of the New Drug Application (NDA) for ARISTADA™ (aripiprazole lauroxil) for the treatment of schizophrenia by the Prescription Drug User Fee Act (PDUFA) action date of Aug. 22, 2015. The FDA indicated that this delay was expected to be brief, measured in terms of weeks, but could not confirm specific timing. The FDA also indicated that no additional data or information is required from Alkermes at this time.

“We are confident in the ARISTADA program and our NDA submission, and we will work closely with the FDA as they complete their review,” said Elliot Ehrich, M.D., Chief Medical Officer of Alkermes. “We look forward to bringing ARISTADA to market as a potential new treatment option to help address the significant unmet medical needs of patients living with schizophrenia.”


ARISTADA is an injectable atypical antipsychotic with one-month and extended-duration formulations in development for the treatment of schizophrenia. Once in the body, ARISTADA converts to aripiprazole. As a long-acting investigational medication based on Alkermes’ proprietary LinkeRx® technology, ARISTADA is designed to have multiple dosing options and to be administered in a ready-to-use, pre-filled product format.
