Study Endpoints

Primary Endpoints

Double-Blind (DB) Induction Phase: Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Day 28
Baseline (Day 1) up to Day 28 (DB phase) induction

MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. Negative change in score indicates improvement.
