Researchers are evaluating the safety and effectiveness of brenipatide alongside standard care compared to a placebo plus standard care in adult participants with major depressive disorder. This study aims to see if brenipatide can delay the return of major depressive symptoms. It is a Phase 3, randomized, double-blind trial sponsored by Eli Lilly and Company. Participants receive brenipatide or placebo through subcutaneous injections combined with their regular treatment. The study includes three periods a screening period lasting about 1 month, a treatment period of at least 12 months, and a follow-up period of about 2 months. The study duration may be shortened if depressive symptoms worsen or if participants withdraw. During the trial, participants will attend regular visits where various assessments will be conducted, including depression rating scales, functional impairment scores, and quality of life questionnaires. Researchers will monitor body weight changes, anxiety levels, and blood samples to measure drug levels and immune responses. The primary outcome is the time until relapse of major depressive disorder symptoms. Safety and adherence to self-injection and study procedures will be closely followed throughout participation.
