Summary

This study tests whether adding NBI-1065845 to standard antidepressants can better relieve depression symptoms in adults who haven't gotten enough help from their current medication. About 200 participants will receive either the study drug or a placebo for 8 weeks. The main goal is to see if depression scores improve more with the add-on treatment.
