ObjectiveThis phase 3, randomized, double-blind, placebo-controlled study evaluated the efficacy and tolerability of fixed-dose levomilnacipran sustained release (SR) compared with placebo in patients with major depressive disorder (MDD); the study was conducted from September 2009-May 2011.MethodOutpatients met DSM-IV-TR criteria for MDD with an ongoing major depressive episode ≥ 8 weeks' duration. After a 1-week placebo lead-in, patients were randomly assigned to receive placebo (n = 179) or levomilnacipran SR 40 mg (n = 181), 80 mg (n = 181), or 120 mg (n = 183) once daily for 8 weeks of double-blind treatment, followed by a 2-week double-blind down-taper. The primary efficacy parameter was change from baseline on the clinician-rated Montgomery-Asberg Depression Rating Scale (MADRS) total score. The prespecified secondary efficacy parameter was change from baseline in Sheehan Disability Scale (SDS) total score. Additional efficacy measures included the 17-item Hamilton Depression Rating Scale (HDRS(17)) and Clinical Global Impressions-Severity of Illness (CGI-S) and -Improvement (CGI-I). Safety and tolerability were also evaluated.ResultsThe least squares mean difference (LSMD) for change from baseline in MADRS total score was significantly superior to placebo for all dose groups: -3.23 (P = .0186), -3.99 (P = .0038), and -4.86 (P = .0005) for levomilnacipran SR 40, 80, and 120 mg, respectively. The LSMD was significantly different for levomilnacipran SR 80 mg and 120 mg versus placebo on the SDS (-2.51 and -2.57, respectively, P < .05 for both doses), HDRS(17) (-2.09 and -2.34, respectively, P < .05 for both doses), CGI-S (-0.43 [P < .01] and -0.35 [P < .05], respectively), and CGI-I (-0.34 and -0.32, respectively, P < .05 for both doses) assessments. The most common treatment-emergent adverse events (≥ 10% of any treatment group) were headache, nausea, constipation, dry mouth, increased heart rate, and hyperhidrosis.ConclusionsLevomilnacipran SR demonstrated significant improvement in depressive symptoms and functioning relative to placebo. In this study, levomilnacipran SR was generally well tolerated.Trial RegistrationClinicalTrials.gov identifier: NCT00969709.© Copyright 2013 Physicians Postgraduate Press, Inc.
