To evaluate the efficacy and safety of AXS-05 relative to bupropion in subjects with treatment resistant major depressive disorder (MDD).
This is a randomized, double-blind, active-controlled, 12-week, two-period study consisting of an open-label, bupropion lead-in period, and a double-blind treatment period. The trial is being conducted in subjects with treatment resistant MDD.
Subjects will be considered to have treatment resistant MDD if they have had a historical inadequate response to 1 or 2 antidepressant treatments and a prospective inadequate response to treatment with bupropion during the open-label, lead-in period.
