The purpose of the study is to assess the safety and effectiveness of risperidone (an antipsychotic medication) in adolescents with schizophrenia over 6 months of treatment.

Official Title: | The Efficacy And Safety Of Risperidone In The Treatment Of Adolescents With Schizophrenia: A Six-Month Open-Label Study. |
Estimated Enrollment: | 560 |
Study Start Date: | April 2001 |
Study Completion Date: | December 2006 |
Although the safety and effectiveness of antipsychotic medications is well-established in adults with schizophrenia, these drugs have not been examined rigorously in adolescents with this disorder. Preliminary experience suggests that risperidone may hold promise for the treatment of these younger subjects. This is an open-label, multicenter trial of risperidone, formulated as an oral solution and tablets, in the treatment of adolescents with schizophrenia. It is an open-label, 6-month extension of two previous double-blind studies that assessed the safety and effectiveness of risperidone in the treatment of schizophrenia in an adolescent population. Patients may also enroll directly in this open-label trial. During the first week of the study, patients will receive increasing doses of risperidone to reach an optimal daily dose (2 to 6 mg/day), which will be maintained throughout the 6 months of the study. Assessments of effectiveness include the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), a scale measuring the symptoms of schizophrenia, the Clinical Global Impression-Severity of Illness subscale (CGI-Severity), a scale measuring the severity of illness, the Clinical Global Impression-Improvement subscale (CGI-Improvement), a scale measuring clinical improvement, and the Children's Global Assessment Scale. Safety evaluations include the incidence of adverse events throughout the study, clinical laboratory tests (hematology, biochemistry, and urinalysis), vital signs (blood pressure, pulse, and temperature), weight, and electrocardiogram (ECG) recordings at specified intervals. The study hypothesis is that risperidone with be effective in the treatment of adolescents with schizophrenia, and well tolerated.
Risperidone, oral solution (1 mg/ml) once daily; dose increasing from 0.01 mg/kg body weight (Day 1) to a range from 2 to 6 mg/day for 6 months. Oral tablets (0.5, 1, 2, 3, and 4 mg) once daily; dose increasing from 0.5 mg (Day 1) to a range of 2 to 6 mg/day for 6 months.
