Trial Outcomes & Findings for Assessing Symptomatic Clinical Episodes in Depression (NCT NCT03595579)

NCT ID: NCT03595579

Last Updated: 2021-09-24

Results Overview

The primary objective of the study was to assess the effect of AXS-05 versus bupropion as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) for change in severity of depressive symptoms. 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.
