A Study of Adjunctive Treatment to Antidepressant Therapy for Adults With Major Depressive Disorder

Eli Lilly and Company227 enrolled

Overview

The primary purpose is to study the efficacy, safety, and tolerability of LY2216684 as an adjunctive treatment for 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) (as defined by history).

This is a 12 week multi-center, double-blind, placebo-controlled study on the efficacy of LY2216684 augmentation of selective serotonin reuptake inhibitors (SSRIs) in participants with MDD who have a partial response to treatment with an SSRI. While remaining on a steady dose of their SSRI treatment at entry into the study, participants will be randomly assigned to adjunctive treatment with LY2216684 or placebo in a 1:1 ratio for 10 weeks of acute treatment.

Outcomes

Primary Outcomes

Change From Baseline to 8 Weeks in Montgomery-Asberg Depression Rating Scale (MADRS)

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

Time frame: Baseline, 8 weeks

Secondary Outcomes

Change From Baseline to 8 Weeks in 16-Item Quick Inventory of Depressive Symptomatology-Self Rated (QIDS-SR16) Total Score

QIDS-SR16 is a 16-item, participant-rated measure of depressive symptomatology with 4 possible answers per question that are specific to the question. Each question (Q) is scored from 0 (no problems) to 3 (increased symptoms). The total score for each visit is the sum of 9 of the 16 items: the highest number from Q1-4 (sleep), number from Q5 (feeling sad), highest number from Q6-9 (appetite and weight), total for Q10-14 (concentration, view of self, thoughts of death or suicide, general interest and energy level respectively) and the highest number from Q15-16 (psychomotor changes). The total score ranges from 0 to 27 with higher scores indicating greater severity of depression. Least Squares (LS) means are calculated using mixed model repeating measures (MMRM) and adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

Change From Baseline to 8 Weeks in Fatigue Associated With Depression Participant-Reported Outcome (FAsD PRO)

The FAsD PRO is a 16-item participant-rated scale. Seven items ask how often the participants experience different aspects of fatigue with each item rated on a 5-point scale: 1 (Never) to 5 (Always). Nine items ask how often fatigue impacts various aspects of the participants lives with each item rated on a 5-point scale: 1 (Not at all) to 5 (Very much). The Fatigue Experience Score is the mean of Items 1-5, and 7, the Fatigue Impact Score is the mean of Items 8-12, 14, and 16, and the Overall Average Score is the mean of Items 1-5, 7-12, 14 and 16. The Experience, Impact and Overall Mean Scores range from 1 to 5, lower scores indicate less experience/impact. Least Squares (LS) means are calculated using analysis of covariance (ANCOVA) and adjusted for treatment, investigator, and baseline score.

Time frame: Baseline, up to 8 weeks
