Researchers are studying the safety and effectiveness of brenipatide, given alongside standard treatment, compared to a placebo with standard treatment, to see if it can delay the return of symptoms in adults with major depressive disorder. This is a Phase 3, randomized, double-blind study involving adult participants aged 18 to 75 years. The trial is designed to assess how long it takes for depression symptoms to relapse after starting the adjunctive treatment. Participants will receive either brenipatide or placebo, both administered by subcutaneous injection, in addition to their stable standard of care medication. The study has three main periods: a screening period lasting about one month, followed by a treatment phase of at least 12 months where participants receive the assigned injections, and finally a follow-up period of roughly two months. The total time in the study can be shorter if symptoms worsen or if a participant withdraws. During the trial, participants will need to attend scheduled visits, self-inject the study drug, maintain study diaries, and complete questionnaires. Researchers will monitor participants closely to determine the time until relapse of major depressive disorder symptoms occurs. Safety and adherence to study procedures will be tracked throughout the trial, with the primary outcome measuring the number of days from randomization until relapse.

Researchers are evaluating how well vortioxetine tablets at doses of 10 mg/day or 20 mg/day work compared to placebo tablets for treating depression symptoms in Japanese teenagers aged 12 to 17 years who have been diagnosed with Major Depressive Disorder (MDD). This phase 3 clinical trial aims to assess the drug's effectiveness, safety, and how the body processes the medication in this pediatric population. Participants will be randomly assigned to receive either vortioxetine or a placebo once daily for 14 weeks. The study includes an initial screening period of up to 15 days to determine eligibility, followed by the 14-week treatment phase. After completing treatment, there is a 4-week period dedicated to monitoring any side effects. Throughout the study, participants will visit the clinic 13 times for assessments and medication administration. During the study, participants will undergo evaluations including the Children Depression Rating Scale Revised version (CDRS-R) to measure changes in depression symptoms from baseline to week 14. Other assessments include safety monitoring and pharmacokinetics. Researchers will also collect information on side effects during and after treatment. The total time commitment for participants is about 20 weeks, including screening, treatment, and follow-up periods.
