The multicenter, randomised, double-blind phase 3 study will evaluate the weight gain profile of ALKS 3831 compared to olanzapine, an established atypical antipsychotic agent with proven efficacy but also metabolic liabilities, in patients with stable schizophrenia over a six-month treatment period.
The ENLIGHTEN clinical development programme for ALKS 3831 is comprised of two key studies: a study evaluating the antipsychotic efficacy of ALKS 3831 compared to placebo over four weeks, and a study assessing weight gain with ALKS 3831 compared to olanzapine in patients with schizophrenia over six months.
The program also includes supportive studies to evaluate the pharmacokinetic and metabolic profile of ALKS 3831, and long-term safety.
ALKS 3831 is composed of samidorphan, a novel, new molecular entity, co-formulated with the established antipsychotic agent, olanzapine, in a single bilayer tablet. ALKS 3831 is designed to provide the strong antipsychotic efficacy of olanzapine and a differentiated safety profile with favorable weight and metabolic properties.
