Placebo Controlled Trial of Valproate and Risperidone in Young Children With Bipolar Disorders

• Status: Completed
• Trial end date: 2011-05-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary aim of this proposal is to conduct a preliminary controlled trial of valproate and risperidone in children ages 3-7 yr. with bipolar disorders. A secondary aim is to carefully characterize these subjects using clinical rating scales and develop pilot data on a very young cohort of children with bipolar disorders that can be used to support an application to NIMH for a prospective, longitudinal study that will provide important information about the course, medication response, neurobiology and outcome of these patients.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Children's Hospital Medical Center, Cincinnati
