Background:

Optimal management of schizophrenia in adolescents is limited by the lack of available therapies. The efficacy and tolerability of aripiprazole was investigated in this patient population.

Methods:

This 6-week, randomized, double-blind, placebo controlled trial was conducted at 101 international centers, with a safety monitoring board. 13-17 year-olds with a DSM-IV diagnosis of schizophrenia were randomized to placebo, or a fixed dose of aripiprazole 10 mg or 30 mg reached after a 5 or 11 day titration, respectively. The primary endpoint was mean change from baseline on the PANSS Total score at week 6. Secondary endpoints included the PANSS Positive and Negative subscales, and CGI Improvement score. Tolerabilility assessements included frequency and severity of adverse events, as well as blood chemistries, metabolic parameters and weight gain.

Results:

Over 85% of 302 patients completed this study. Both 10 mg and 30 mg doses were superior to placebo on the primary endpoint (PANSS total), with significant differences observed as early as Week 1 (30mg). Both doses showed significant improvement on the PANSS Positive and CGI-I scales; and the 10 mg dose group was superior on PANSS Negative score. Approximately 5% of aripiprazole patients discontinued due to AEs. Weight gain and changes in prolactin were minimal.

Conclusions:

10mg and 30mg doses of aripiprazole were superior to placebo in the treatment of adolescents with schizophrenia. Aripiprazole was well tolerated, in general, with few discontinuations due to AEs. EPS was the most common AE. Change in body weight was similar to placebo.
