Montgomery Asberg Depression Rating Scale (MADRS) Change From Baseline to Week 3

MADRS is a clinician-rated scale measuring depression symptom severity, consisting of 10 items, each scored from 0 (normal) to 6 (severe), for a total possible score of between 0 to 60; higher scores denote greater severity. Response >= 50% decrease and remission <= 10 total score.
