'Schizophrenia and bipolar I disorder are complex, chronic diseases and there remains a persistent need for new medications with proven efficacy and safety. Olanzapine, a highly-efficacious atypical antipsychotic, is associated with significant side effects, including weight gain, that may impact patients' treatment experiences and limit its use,' said
'LYBALVI represents an important new treatment option for adults with schizophrenia or bipolar I disorder, their clinicians and caregivers, and reflects Alkermes' commitment to developing new therapies that support patient-centered care,' said
In the ENLIGHTEN clinical development program, LYBALVI demonstrated antipsychotic efficacy, safety and tolerability, including statistically significantly less weight gain than olanzapine in patients with schizophrenia in the ENLIGHTEN-2 study. Results from the ENLIGHTEN program's pivotal ENLIGHTEN-1 efficacy study and ENLIGHTEN-2 weight study have been published in peer-reviewed journals1,2 and are included in the approved labeling for LYBALVI. The FDA approved LYBALVI under the 505(b)(2) regulatory pathway based on data from 27 clinical studies, including 18 studies evaluating LYBALVI and nine studies evaluating samidorphan alone, and the
'People living with schizophrenia or bipolar I disorder must evaluate both efficacy and tolerability when making treatment decisions,' said
Alkermes expects to make LYBALVI available for patients in the fourth quarter of 2021.

About the ENLIGHTEN Clinical Development Program
The ENLIGHTEN clinical development program for LYBALVI includes two key studies in patients with schizophrenia: ENLIGHTEN-1 and ENLIGHTEN-2.
