- Change in MADRS Total Score From Baseline to Week 6 [ Time Frame: 6 weeks ]The primary objective of the study was to evaluate the efficacy of AXS-05 as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) for change in severity of depressive symptoms from baseline to Week 6. The MADRS is a 10-item scale and items are scored between 0-6 points. For each item, a score of 0 indicates the absence of symptoms, and a score of 6 indicates symptoms of maximum severity. A maximum total score is 60 points.
