The primary objective of this study was to assess the maintenance of efficacy of LY2216684 compared with placebo as adjunctive therapy to selective serotonin reuptake inhibitors (SSRIs) as measured by the time-to-symptom reemergence among participants with major depressive disorder (MDD) who met randomization criteria with adjunctive LY2216684 during the stabilization period. This trial consists of two distinct periods: an open-label treatment period, which consists of two parts, 8 weeks acute open-label with movement to 12 weeks open-label stabilization if participants are in remission at end of 8 weeks (open-label for 20 weeks total) followed by a randomized, double-blind, placebo-controlled period for 24 weeks.
In order to enter the Stabilization Open-label Period, participants must have met remission criteria, defined as a Montgomery-Asberg Depression Rating Scale (MADRS) total score ≤10 at Week 8. In order to enter the Double-blind Randomization Withdrawal Period, participants must have met randomization criteria, defined as a MADRS total score ≤10 at Weeks 18, 19, and 20.
Participants should have been on their SSRI for at least 8 weeks prior and were to continue on their stable dose throughout the study.
