| | DUBLIN, March 4, 2020 /PRNewswire/ -- Alkermes plc (Nasdaq: ALKS) today announced the publication of results from the phase 3 ENLIGHTEN-1 clinical trial of ALKS 3831 (olanzapine/samidorphan) in the peer-reviewed publication, Journal of Clinical Psychiatry. ENLIGHTEN-1 was a four-week study evaluating the efficacy, safety and tolerability of ALKS 3831 compared to placebo in 403 patients experiencing an acute exacerbation of schizophrenia. Positive topline data from the ENLIGHTEN-1 study were first reported in June 2017. A New Drug Application (NDA) for ALKS 3831 is currently under U.S. Food and Drug Administration (FDA) review, with a Prescription Drug User Fee Act (PDUFA) target action date of Nov. 15, 2020. “Despite the availability of many therapeutic options for schizophrenia and bipolar I disorder, there remains a persistent unmet need for new and effective antipsychotic medicines,” said Jelena Kunovac, M.D., M.S., Founder and President of Altea Research, and publication co-author. “If approved, ALKS 3831 has the potential to be a compelling addition to the treatment landscape for these serious and chronic diseases.” “The ALKS 3831 development program is an example of Alkermes’ commitment to developing new treatment options that may help people living with serious mental illness,” said Craig Hopkinson, M.D., Executive Vice President, Research & Development and Chief Medical Officer at Alkermes. “We look forward to continuing to work with the FDA as it reviews the NDA for ALKS 3831, with the goal of helping to bring this potential new medicine to patients and their families.” ENLIGHTEN-1 is one of two key studies included in the ALKS 3831 ENLIGHTEN clinical development program. ENLIGHTEN-2, the second phase 3 study, assessed weight gain with ALKS 3831 compared to olanzapine over six months. Positive topline data from the ENLIGHTEN-2 study were reported in November 2018.

About Bipolar I Disorder
Bipolar disorder is a brain disorder that causes unusual shifts in a person’s mood, energy and ability to function.
