The overall time each participant will be in the study is about 20 weeks. This includes up to 15 days (about 2 weeks) to check who can take part, a 14-week period where everyone receives vortioxetine or a placebo, and after that, a 4-week period to check for any side effects after treatment. During the study, participants will visit their clinic 13 times.
