摘要
Purpose/Background: Brexpiprazole was approved for adjunctive treatment of major depressive disorder (MDD) in 2015. Because only a small number of randomized controlled trials have investigated the use of brexpiprazole in MDD, we performed a meta-analysis. Methods/Procedures: We systematically searched literatures in PubMed, Cochrane Library database, EMBASE, Google Scholar, and clinicaltrials.gov up to January 2016. The primary efficacy measure was the mean change in total Montgomery-Asberg Depression Rating Scale (MADRS) score from baseline. Secondary efficacy measures were the mean change in total Hamilton Rating Scale for Depression (17 items) score from baseline and the response (>= 50% reduction in MADRS total score) and remission (MADRS total score <= 10 with >= 50% reduction) rates. Findings/Results: Four studies fulfilled the inclusion criteria and were included in the analysis. Brexpiprazole showed superior efficacy over placebo with effect sizes (mean differences) of -1.76 (95% confidence interval [CI], -2.45 to -1.07) for MADRS and -1.21 (95% CI, -1.71 to -0.72) for the 17-item Hamilton Rating Scale for Depression. The risk ratios for response and remission were 1.57 (95% CI, 1.29-1.91) and 1.55 (95% CI, 1.22-1.96), respectively. The incidences of discontinuation due to adverse events, akathisia, and weight increase were higher in the brexpiprazole group than in the placebo group, with risk ratios of 3.44 (95% CI, 1.52-7.80), 3.39 (95% CI, 2.08-5.51), and 4.36 (95% CI, 2.45-7.77), respectively, and the incidence of akathisia was related to the brexpiprazole dose. Implications/Conclusions: Although our results suggest that brexpiprazole could be an effective adjunctive agent for MDD, they should be cautiously translated into clinical practice because the meta-analysis was based on only a handful of randomized controlled trials.
