Phase 3 Study of Azetukalner Compared to Placebo for Adults with Moderate-to-Severe Major Depressive Disorder

What this Trial Is About

Researchers are evaluating azetukalner as a treatment for adults diagnosed with moderate-to-severe Major Depressive Disorder MDD. This Phase 3, randomized, double-blind, placebo-controlled study aims to assess the clinical efficacy, safety, and tolerability of azetukalner when taken alone. The study involves participants aged 18 to 74 who have experienced their first major depressive episode before age 50. Participants receive either azetukalner 20 mg or a placebo orally once a day with food, preferably with the evening meal, for a total of 6 weeks. The study includes two groups one taking azetukalner and the other taking placebo, both under blinded conditions to ensure unbiased results. During the study, participants will be regularly monitored through clinical evaluations, including changes in depression severity scores such as the Hamilton Depression Rating Scale HAMD-17 and other scales measuring pleasure and clinical global impression. Safety and tolerability will be observed from screening through 8 weeks after the final dose. The total study duration includes screening, 6 weeks of treatment, and post-treatment safety follow-up.
