Abstract

Abstract : Objective: These post hoc analyses evaluate the efficacy, safety, and tolerability of vortioxetine versus placebo in patients aged ≥55 years with major depressive disorder (MDD). Methods: Study-level efficacy data from 12 short-term, fixed-dose, randomized, placebo-controlled trials of vortioxetine 5–20 mg/day were assessed using a random-effects meta-analysis. Adverse events (AEs), vital signs, ECG values, liver enzymes, and body weight were pooled from the same studies. Patients had baseline Montgomery–Åsberg Depression Rating Scale (MADRS) total scores ranging from 22–30. Results: 1508 patients (mean age=62.4 years; range, 55–88 years) were included. Mean differences from placebo in change from baseline to study end (6/8 weeks) in MADRS were –2.56 (5 mg, n=324, P =0.035), –2.87 (10 mg, n=222, P =0.007), –1.32 (15 mg, n=90, P =NS), and –4.65 (20 mg, n=165, P =0.012). Odds ratios for response versus placebo were 1.6 (5 mg, P =NS), 1.8 (10 mg, P =0.002), 1.2 (15 mg, P =NS), and 2.5 (20 mg, P <0.001), and for remission versus placebo were 1.5 (5 mg, P =NS), 1.5 (10 mg, P =NS), 1.4 (15 mg, P =NS), and 2.7 (20 mg, P =0.001). The proportion of patients with AEs for placebo and vortioxetine 5–20 mg was 61.5% and 62.3%, respectively, with no increase at increased doses. Vortioxetine demonstrated a placebo-level incidence of serious AEs (1.2%). AEs occurring in ≥5% of any treatment group were nausea, headache, diarrhea, dizziness, dry mouth, constipation, fatigue, vomiting, and anxiety. No clinically significant mean changes in vital signs, ECG values, liver enzymes, or body weight emerged during treatment. Conclusion: Vortioxetine 5–20 mg/day is efficacious and well tolerated in MDD patients aged ≥55 years, a group that is often comorbid with other conditions and treated with other medications.
