PG - 1533-40 LID - 10.1542/peds.2008-3782 [doi] AB - OBJECTIVE: The objective of this study was to evaluate short-term efficacy and safety of aripiprazole in the treatment of irritability in children and adolescents with autistic disorder who were manifesting behaviors such as tantrums, aggression, self-injurious behavior, or a combination of these. METHODS: This 8-week, double-blind, randomized, placebo-controlled, parallel-group study was conducted of children and adolescents (aged 6-17 years) with autistic disorder. Patients were randomly assigned (1:1) to flexibly dosed aripiprazole (target dosage: 5, 10, or 15 mg/day) or placebo. Efficacy outcome measures included the Aberrant Behavior Checklist irritability subscale and the Clinical Global Impression-Improvement score (CGI-I). Safety and tolerability were also assessed. RESULTS: Ninety-eight patients were randomly assigned to receive placebo (n = 51) or aripiprazole (n = 47). Mean improvement in Aberrant Behavior Checklist irritability subscale score was significantly greater with aripiprazole than with placebo from week 1 through week 8. Aripiprazole demonstrated significantly greater global improvements than placebo, as assessed by the mean CGI-I score from week 1 through week 8; however, clinically significant residual symptoms may still persist for some patients. Discontinuation rates as a result of adverse events (AEs) were 10.6% for aripiprazole and 5.9% for placebo. Extrapyramidal symptom-related AE rates were 14.9% for aripiprazole and 8.0% for placebo. No serious AEs were reported. Mean weight gain was 2.0 kg on aripiprazole and 0.8 kg on placebo at week 8. CONCLUSIONS: Aripiprazole was efficacious in children and adolescents with irritability associated with autistic disorder and was generally safe and well tolerated.
