Arm Intervention/treatment
Experimental: AXS-05 Drug: AXS-05
AXS-05 taken twice daily for 6 weeks.

Active Comparator: Bupropion Drug: Bupropion
Bupropion taken twice daily for 6 weeks.




Primary Outcome Measures :
  1. MADRS Score - Overall Change From Baseline [ Time Frame: Assessed at week 1, 2, 3, 4, 5 and 6 (averaged over the entire 6-week treatment period) ]
    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.


Other Outcome Measures:
