Study Summary

The primary purpose of this study is to assess whether at least 1 dose of LY2216684 (12 milligrams \[mg\] or 18 mg once daily) is superior to placebo once daily in the adjunctive treatment of participants with major depressive disorder (MDD) who were identified as partial responders to an adequate course of treatment with a selective serotonin reuptake inhibitor (SSRI) during an 8-week, double-blind, acute adjunctive treatment phase.

Primary Outcome

The MADRS is a rating scale for severity of depressive mood symptoms. The MADRS had a 10-item checklist. Items were rated on a scale of 0 to 6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). Least Squares (LS) means were calculated using mixed model repeated measures (MMRM) adjusting for treatment, investigator, visit, baseline score, treatment-by-visit and baseline score-by-visit.
