Geodon in Weight Loss Study for Bipolar Disorders

This study has been completed.

This research study is designed to determine if replacing your current antipsychotic and/or mood stabilizer with ziprasidone (Geodon) will impact weight. This research is being conducted because Geodon has a documented effect on mood. Additionally, we believe Geodon to be an effective medication for overweight or obese patients with bipolar disorder. There will be approximately 25 patients enrolled in this study.

Condition Intervention Phase
Bipolar Disorder Drug: Ziprasidone/Geodon Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: Adjunctive Ziprasidone in Overweight and Obese Patients With Bipolar Disorder

Primary Outcome Measures:
  • The Primary Outcome Measure Was Weight Change From Baseline to Endpoint. [ Time Frame: Baseline, 12 weeks ]
    The primary outcome measure will be the change in weight from baseline to endpoint using a random regression mixed effects model.

Secondary Outcome Measures:
  • Changes From Baseline to Endpoint in Body Mass Index (BMI) [ Time Frame: Baseline, 12 weeks ]
    Secondary outcome measures will include the change from baseline to endpoint in Body Mass Index (BMI).

Enrollment: 25
Study Start Date: January 2007
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
