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

What this Trial Is About

Researchers are evaluating azetukalner as a monotherapy in adults diagnosed with Major Depressive Disorder MDD. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study aims to assess the clinical efficacy, safety, and tolerability of azetukalner compared to placebo in adults with moderate-to-severe MDD. Participants are adults aged 18 to 74 years with a current major depressive episode lasting between 6 weeks and 24 months. Participants will be randomly assigned to receive either azetukalner 20 mg or placebo, both taken orally once daily with food, preferably with the evening meal, for 6 weeks. The study uses a parallel design and includes a placebo comparator. Azetukalner and placebo are administered as daily oral doses over the treatment period. During the study, participants will undergo assessments including the Hamilton Depression Rating Scale HAMD-17 at baseline, Week 1, and Week 6, the Snaith-Hamilton Pleasure Scale SHAPS, and the Clinical Global Impression of Severity CGI-S score at Week 6. Safety and tolerability are monitored from screening through 8 weeks after the final dose. The primary outcome is the change from baseline in HAMD-17 at Week 6. Total participation may last several months, including screening, treatment, and follow-up periods.
