Introduction: Considering that the efficacy results of the Japan lurasidone phase 3 trials for acute schizophrenia were inconsistent, we conducted a systematic review and a random-effect model network meta-analysis of those trials to examine whether lurasidone was beneficial for the treatment of Japanese patients with acute schizophrenia. Methods: The study included the double-blind, randomized trial in Japan that included patients with acute schizophrenia. Efficacy outcomes were improvement of the Positive and Negative Syndrome Scale total score (PANSS-T, primary), positive (PANSS-P), negative (PANSS-N), and general (PANSS-G) subscale scores; and Clinical Global Impression-Severity Scale (CGI-S) score and response rate. Other outcomes were discontinuation rates and incidence of individual adverse events. Results: We included four studies (n = 1,608). Although both lurasidone 40 mg/d (LUR40) and 80 mg/d (LUR80) outperformed placebo in PANSS-T [standardized mean difference (95% credible interval): LUR40 = −0.298 (−0.420, −0.176), LUR80 = −0.170 (−0.320, −0.019)], PANSS-P, and CGI-S scores, LUR40 but not LUR80 outperformed placebo in PANSS-N and PANSS-G scores and response rate. LUR40 outperformed LUR80 regarding PANSS-G score. Both LUR40 and LUR80 were associated with a higher incidence of akathisia, somnolence, and increased body weight compared with placebo. Compared with placebo, LUR40 was associated with a higher incidence of weight gain (≥7%), and LUR80 was associated with a higher incidence of dystonia and weight loss (≥7%) and higher Drug-Induced Extrapyramidal Symptoms Scale score. Conclusions: Both LUR40 and LUR80 improved overall symptoms in Japanese patients with acute schizophrenia. However, LUR80 seemed to have a risk of extrapyramidal symptoms.
