About the ENLIGHTEN Clinical Development Program
The ENLIGHTEN clinical development program for ALKS 3831 includes two key studies in patients with schizophrenia: the ENLIGHTEN-1 study, which evaluated the antipsychotic efficacy of ALKS 3831 compared to placebo over four weeks, and the ENLIGHTEN-2 study, which assessed weight gain with ALKS 3831 compared to olanzapine over six months. The program also includes supportive studies to evaluate the pharmacokinetic and metabolic profile and long-term safety of ALKS 3831, and pharmacokinetic bridging studies comparing ALKS 3831 and ZYPREXA.
