    AbstractObjective: To compare the rates of successfully treated patients (STPs) with vortioxetine versus venlafaxine in major depressive disorder (MDD), using dual endpoints that combine improvement of mood symptoms with optimal tolerability or functional remission, and conduct a simplified cost-effectiveness analysis.Methods: The 8-week SOLUTION study (NCT01571453) assessed the efficacy and safety of vortioxetine (10 mg/day) versus venlafaxine XR (150 mg/day) in adult Asian patients with MDD. Rates were calculated post-hoc of STP Mood and Tolerability (≥50% reduction from baseline in Montgomery-Åsberg Depression Rating Scale [MADRS] total score and no treatment-emergent adverse events) and STP Mood and Functioning (≥50% reduction from baseline in MADRS total score and Sheehan Disability Scale total score ≤6). The incremental costs per STP were assessed using the 2018 pharmacy purchase prices for branded vortioxetine/branded venlafaxine in China as the base case.Results: STP Mood and Tolerability rates were 28.9% for vortioxetine and 19.9% for venlafaxine (p = .028); the corresponding STP Mood and Functioning rates were 28.0% and 23.5% (p = .281). Drug costs for the 8-week treatment period were CN¥1954 for vortioxetine and CN¥700 for venlafaxine. The incremental cost per STP for vortioxetine versus venlafaxine was CN¥13,938 for Mood and Tolerability and CN¥27,876 for Mood and Functioning.Conclusions: Higher rates of dual treatment success were seen with vortioxetine versus venlafaxine. Although vortioxetine was not dominant in the base case, the incremental cost per STP for vortioxetine versus venlafaxine were overall within acceptable ranges. These results support the benefits previously reported with vortioxetine versus other antidepressants in broad efficacy, tolerability profile and cost-effectiveness.
