General information about the trial
|
|||
Main objective of the trial |
To assess the efficacy of oral ziprasidone compared with placebo in the treatment of children and adolescents aged 10-17 with Bipolar I Disorder (current or most recent episode manic) as measured by the change from baseline to Week 4 in the Young Mania Rating Scale (YMRS) total score. To evaluate the safety and tolerability of oral ziprasidone over 4 weeks in the treatment of children and adolescents with Bipolar I Disorder (current or most recent episode manic).
|
||

Arm description |
Subjects were randomised to receive ziprasidone capsules orally once daily for 4 weeks. Dose was titrated over the first 7-14 days of treatment, and the stable dose was maintained for remaining treatment period. Subjects with body weight less than 45 kilogram (kg) received 60 to 80 milligram per day (mg/day) and subjects with body weight greater than or equal to (>=) 45 kg received 120-160 mg/day, as per investigator discretion. Subjects after completion or discontinuation of treatment were eligible to enroll in open label extension study A1281201 or were followed-up to 35 days (5 weeks) after last dose in this study. | |||||||||||||||||||||||||||||||||||||||

Change From Baseline in Young Mania Rating Scale (YMRS) Total Score at Week 4 | ||||||||||||
End point description |
YMRS: an 11-item scale that measured the severity of manic episodes. Four items (irritability, speech, thought content, and disruptive/ aggressive behavior) were rated on a scale from 0 (symptom absent) to 8 (symptom extremely severe). The remaining items were rated on a scale from 0 (symptom absent) to 4 (symptom extremely severe). YMRS total score was sum of score of all 11 items and ranged from 0 (no symptoms) to 60 (extreme severity of symptoms), higher score indicated higher severity of mania. Intent-to-treat (ITT): all randomised subjects who had baseline measurements, took at least 1 dose of study medication (ziprasidone or placebo) and with at least 1 post-baseline visit.

An AE was any untoward medical occurrence in a subject who received study medication without regard to possibility of causal relationship to it. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalisation; life-threatening experience (immediate risk of dying); persistent or significant disability/ incapacity; congenital anomaly. AEs included both serious and all non-serious AEs. The safety analysis set included all subjects who were randomised and took at least 1 dose of study medication (ziprasidone or placebo).

End point description |
C-SSRS: a measure used to identify and assess subjects at risk for suicide. It is a semi-structured interview that captures the occurrence, severity, and frequency of suicide-related thoughts and behaviors. C-SSRS items were mapped to the following C-CASA categories: completed suicide, attempted suicide (actual attempt; aborted attempt; interrupted attempt), non-suicidal self-injurious behavior (SIB), preparatory acts, suicidal ideation (wish to be dead; non-specific active suicidal thoughts [AST]; active suicidal ideation [ASI] with any methods [not plan], without intent to act; ASI with some intent to act, without specific plan; ASI with specific plan and intent; SIB, no suicidal intent). ITT population included all randomised subjects who had baseline measurements, took at least 1 dose of study medication (ziprasidone or placebo) and with at least 1 post-baseline visit. “n” = number of subjects evaluable for specified categories.

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 (maximum impairment). Higher scores indicated greater impairment. Total score calculated as sum of the 17 items ranged from 1 (no impairment) to 119 (maximum impairment); higher score indicated greater impairment. ITT population included all randomised subjects who had baseline measurements, took at least 1 dose of study medication (ziprasidone or placebo) and with at least 1 post-baseline visit.

AIMS: clinician rated 12-item scale to document occurrences of dyskinesia in subjects, specifically tardive dyskinesia. Items 1 to 10, scored as 0 (none) to 4 (severe); higher score indicates greater severity. Items 11 to 14 are questions with No or Yes response. Only the sum of the first 7 items were calculated to evaluate AIMS movement cluster score with a core range of 0 (none) to 28 (extreme severity); higher score indicates greater severity. ITT population included all randomised subjects who had baseline measurements, took at least 1 dose of study medication (ziprasidone or placebo) and with at least 1 post-baseline visit.

Reporting group description |
Subjects were randomised to receive ziprasidone capsules orally once daily for 4 weeks. Dose was titrated over the first 7-14 days of treatment, and the stable dose was maintained for remaining treatment period. Subjects with body weight less than 45 kg received 60 to 80 mg/day and subjects with body weight >=45 kg received 120-160 mg/day, as per investigator discretion. Subjects after completion or discontinuation of treatment were eligible to enroll in open label extension study A1281201 or were followed-up to 35 days (5 weeks) after last dose in this study. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
