Introduction: This analysis assessed the relative efficacy and tolerability of lurasidone versus other atypical antipsychotics in the treatment of pediatric schizophrenia.
Methods: A systematic literature review identified 13 randomized-controlled trials for the treatment of pediatric schizophrenia. A Bayesian network meta-analysis compared the efficacy and tolerability of the following atypical antipsychotics: aripiprazole, asenapine, clozapine, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, and ziprasidone. Patients were 7-17 years old and trial duration ranged from 6-12 weeks. Outcomes included Positive and Negative Syndrome Scale (PANSS), Clinical Global Impressions-Severity (CGI-S), weight gain, all-cause treatment discontinuation, and extrapyramidal symptoms. Results from the fixed effect models were reported as mean differences for continuous outcomes and odds ratios for binary outcomes; each with a 95% credible interval.
Results: Lurasidone had significantly greater improvement compared with placebo for PANSS (-7.95 [-11.76, -4.16]) and CGI-S (-0.44 [-0.67, -0.22]), but did not differ from comparators. The differences in weight gain for lurasidone relative to comparators were as follows: clozapine (-3.81kg [-8.03, 0.42]), olanzapine (-3.62kg [-4.84, -2.41]), quetiapine (-2.13kg [-3.20, -1.08]), risperidone (-1.16kg [-2.14, -0.17]), asenapine (-0.98kg [-1.71, -0.24]), paliperidone (-0.85kg [-1.57, -0.14]), aripiprazole (-0.15kg [-0.88, 0.58]), and ziprasidone (0.38kg [-0.49, 1.24]); all were statistically significant except for clozapine, aripiprazole, and ziprasidone. Rates of all-cause discontinuation and extrapyramidal symptoms were similar for lurasidone and comparators, except aripiprazole and paliperidone, which had higher rates of all-cause discontinuation.
Conclusions: In this network meta-analysis of atypical antipsychotics for the treatment of pediatric schizophrenia, lurasidone was associated with similar efficacy, but less weight gain than active comparators.
