AN OPEN TRIAL OF CLOZAPINE IN 11 ADOLESCENTS WITH CHILDHOOD-ONSET SCHIZOPHRENIA

To review the response of 11 adolescents with childhood-onset schizophrenia to a 6-week open clozapine trial. Method: Eleven children meeting DSM-III-R criteria for schizophrenia had a 6-week open trial of clozapine (mean sixth week daily dose 370 mg). Behavioral ratings included the Brief Psychiatric Rating Scale and Children's Global Assessment Scale. Results: More than half showed marked improvement in Brief Psychiatric Rating Scale ratings by 6 weeks of clozapine therapy compared to admission drug rating and compared to a systematic 6-week trial of haloperidol. Conclusions: This open trial indicates that clozapine may be a promising treatment for children and adolescents with schizophrenia who do not respond well to typical neuroleptics. A double-blind placebo-controlled study is ongoing.
