Extension Study Evaluating The Safety And Tolerability Of Flexible Doses Of Oral Ziprasidone In Children And Adolescents With Bipolar I Disorder

Phase 3TerminatedNCT03768726

Pfizer's Upjohn has merged with Mylan to form Viatris Inc.23 enrolled

Overview

This 26-week open-label extension study is designed to provide information on the safety and tolerability of oral ziprasidone (20-80 mg BID (twice daily) with meals) during long-term administration in children and adolescents with Bipolar I Disorder (current or most recent episode manic).

Study A1281201 is a 6 month, open label extension study of the ongoing double blind, randomized, placebo controlled study of ziprasidone in pediatric Bipolar Disorder (Study A1281198). Study A1281201 will enroll adolescents aged 10 to 17 years with Bipolar I Disorder who have participated in double blind Study A1281198. In order to be enrolled in this open label extension trial, subjects must have met the enrollment criteria for Study A1281198, and must meet the inclusion and exclusion criteria for Study A1281201 at the extension study Baseline visit (last visit in the double blind study). The purpose of adding this extension study to the ongoing Geodon pediatric bipolar program is to obtain additional longer term safety data in children and adolescents with Bipolar I disorder treated with ziprasidone.

ZiprasidoneDRUG

All investigational products will be provided by Pfizer and will include oral ziprasidone capsules of 20, 40, 60, and 80 mg strength. Matching placebo capsules will also be supplied for the initial 1-14 day dose transition period. During the transition period all subjects will receive both active ziprasidone and placebo capsules. The placebo capsules are used to maintain the blind to the treatment assignment of the subjects in A1281198 . All medication will be packaged in childproof blister cards with columns for AM and for PM capsules. During the dose transition period (Weeks 1-2, Days 1-14), subjects will receive a study drug blister card for each week of transition dosing. Subjects weighing greater than 45 kg will receive 2 weeks of transition medication, while subjects weighing less than 45 kg will receive 1 week of transition medication.
