Study summary

The purpose of this study is to assess the safety and tolerability of ziprasidone during long-term open-label administration in adolescents (ages 13-17) with schizophrenia.

Read the detailed description

On March 24, 2009, Pfizer Inc. stopped late stage Geodon pediatric clinical trials in schizophrenia (A1281134 - placebo controlled; A1281135 - open label). As recommended by the DSMB, these studies were stopped due to lack of efficacy. No safety concerns were identified.

    Time frame: 26 weeks

Secondary outcomes

  1. Number of Subjects With Change From Baseline to Each Pubertal Stage of Development as Assessed by the Tanner Adolescent Pubertal Self Assessment

    Tanner Adolescent Pubertal Staging Questionnaire: used to document the stage of development of secondary sexual characteristics.

Rated in 5 stages: stage 1 (no development) to 5 (adult-like development in quantity and size).

    Time frame: Baseline, Week 26, Early Termination (ET)

  2. Change From Baseline in Children's Problem Behavior and Aggression Questionnaire (CPBAQ) Total Score

    CPBAQ: 19-item parent or legal guardian completed questionnaire to rate the child's verbal (such as yelling or cursing) and physical aggression (such a fighting with peers or being cruel to an animal) during the past week. Behavior was rated on a 4-point scale; range 0 (behavior did not occur or was not a problem) to 3 (behavior occurred a lot or was severe problem).

  3. Change From Baseline in Child Depression Rating Scale - Revised (CDRS-R): Total Score

    CDRS-R: clinician-rated interview-based scale (with both child and parent or guardian) to assess 17 distinct symptom areas to derive an index of depression severity. Discrepancies between informants' responses were resolved by using most impaired rating given by valid informant. Rated on a 7-point scale; range from 1 (no impairment) to 7 (indicates greater impairment). Total score calculated as sum of the 17 items (range 1 to 119); higher score indicates greater impairment.

SecondaryNumber of Subjects Per Response on the School Placement Questionnaire: School Situation

School placement questionnaire: parent or legal guardian assessed questionnaire to determine whether the child is currently enrolled in school (or planned to be enrolled if on school holiday like summer break), whether attending regularly if enrolled, and how well the child is doing overall in school. Questions were modified from those used in the National Institute of Mental Health (NIMH) funded Treatment of Early Onset Schizophrenia Spectrum (TEOSS) study. Results determine whether subjects are currently attending school and qualitatively describe how well they are doing in school.
