FDA Advisory Committee Votes in Support of ALKS 3831 for the Treatment of Schizophrenia and Bipolar I Disorder

DUBLIN, Oct. 9, 2020 /PRNewswire/ — Alkermes plc (Nasdaq: ALKS) today announced positive voting outcomes from the joint meeting of the Psychopharmacologic Drugs Advisory Committee and the Drug Safety and Risk Management Advisory Committee, appointed by the U.S. Food and Drug Administration (FDA). The committees met to discuss ALKS 3831 (olanzapine/samidorphan), an investigational, novel, once-daily, oral atypical antipsychotic drug candidate for the treatment of adults with schizophrenia and for the treatment of adults with bipolar I disorder. The committees jointly voted that samidorphan meaningfully mitigates olanzapine-associated weight gain (16 yes, 1 no) and that the safety profile of ALKS 3831 has been adequately characterized (13 yes, 3 no, 1 abstention). 

“The favorable outcome of today’s joint advisory committee meeting represents an important milestone for the patients, clinicians and families who may benefit from new medicines for the treatment of schizophrenia and bipolar I disorder. The personal testimonies shared during today’s open public hearing reinforced the need for treatment approaches that consider patients’ overall mental and physical health,” said Craig Hopkinson, M.D., Chief Medical Officer and Executive Vice President of Research & Development at Alkermes. “The ALKS 3831 development program is part of our ongoing commitment to develop new therapeutic options for adults living with serious mental illness. Today’s outcome marks an important step for this program and we look forward to working with the FDA as it completes its review of the ALKS 3831 New Drug Application.”

In addition, the committees jointly voted that labeling is sufficient to mitigate the risks related to the opioid antagonist action of samidorphan (11 yes, 6 no). Alkermes’ proposed labeling contraindicates the use of ALKS 3831 in patients who are opioid-dependent or chronically using opioids, and the company has proposed a comprehensive education plan, which includes dissemination of information to potential prescribers and pharmacists.

The joint advisory committee’s recommendations, while not binding, will be considered by the FDA in its review of the ALKS 3831 New Drug Application (NDA). The Prescription Drug User Fee Act (PDUFA) target action date for the ALKS 3831 NDA is Nov. 15, 2020.

The NDA submission and clinical development program for ALKS 3831 are supported by data from 27 clinical studies, including 18 studies evaluating ALKS 3831 and nine studies evaluating samidorphan alone.
