Background Analysis of efficacy and tolerability of vortioxetine 20 mg/day, and optimal timing of dose adjustment, in patients with major depressive disorder (MDD). Methods Pooled analysis of six randomized, fixed-dose studies of vortioxetine 5 to 20 mg/day. Mean change from baseline in Montgomery-angstrom sberg Depression Rating Scale (MADRS) total score was analyzed by vortioxetine dose using a mixed model for repeated measures. Tolerability was assessed over the 8-week treatment period and from day 8 (ie, following dose increase to 20 mg/day). Data from three randomized, flexible-dose studies were examined for frequency and timing of dose adjustment. Results A clear dose-response relationship for vortioxetine was confirmed in terms of improvement in MADRS total score. Significant differences vs placebo were seen for vortioxetine 20 mg/day from week 2 onwards; vortioxetine 10 mg did not separate from placebo until week 4. At week 8, mean change in MADRS total score from baseline was significantly greater for vortioxetine 20 mg/day vs 10 mg/day (difference, -1.03 points; P < .05). Incidence of adverse events was not increased in patients who received vortioxetine 20 mg/day vs 10 mg/day. In flexible-dose studies, dosage was increased to 20 mg/day after 1 week in 48.0% of patients; final dosage was 20 mg/day in 64.3% of patients. Conclusions Vortioxetine 20 mg is significantly more effective than vortioxetine 10 mg in patients with MDD, with a similar tolerability profile. In flexible-dose studies, almost half of all patients received 20 mg/day after 1 week and two-thirds received 20 mg/day as their final dosage. © The Author(s), 2021.

Abstract
Background Analysis of efficacy and tolerability of vortioxetine 20 mg/day, and optimal timing of dose adjustment, in patients with major depressive disorder (MDD). Methods Pooled analysis of six randomized, fixed-dose studies of vortioxetine 5 to 20 mg/day. Mean change from baseline in Montgomery-angstrom sberg Depression Rating Scale (MADRS) total score was analyzed by vortioxetine dose using a mixed model for repeated measures. Tolerability was assessed over the 8-week treatment period and from day 8 (ie, following dose increase to 20 mg/day). Data from three randomized, flexible-dose studies were examined for frequency and timing of dose adjustment. Results A clear dose-response relationship for vortioxetine was confirmed in terms of improvement in MADRS total score. Significant differences vs placebo were seen for vortioxetine 20 mg/day from week 2 onwards; vortioxetine 10 mg did not separate from placebo until week 4. At week 8, mean change in MADRS total score from baseline was significantly greater for vortioxetine 20 mg/day vs 10 mg/day (difference, -1.03 points; P < .05). Incidence of adverse events was not increased in patients who received vortioxetine 20 mg/day vs 10 mg/day. In flexible-dose studies, dosage was increased to 20 mg/day after 1 week in 48.0% of patients; final dosage was 20 mg/day in 64.3% of patients. Conclusions Vortioxetine 20 mg is significantly more effective than vortioxetine 10 mg in patients with MDD, with a similar tolerability profile.
