  Purpose
The purpose of this study is to determine if ziprasidone plus a mood stabilizer will continue to be a safe and effective treatment regimen for adults with Bipolar I Disorder (manic or mixed symptoms) after they have achieved 8 consecutive weeks of symptom improvement on the regimen.

Condition Intervention Phase
Bipolar Mania Bipolar Disorder Drug: Placebo Drug: Ziprasidone Oral Capsule Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3, Randomized, 6-Month, Double-Blind Trial in Subjects With Bipolar I Disorder to Evaluate the Continued Safety and Maintenance of Effect of Ziprasidone Plus a Mood Stabilizer (vs Placebo Plus a Mood Stabilizer) Following a Minimum of 2 Months of Response to Open-Label Treatment With Both Agents

Primary Outcome Measures:
  • Time to Intervention for a Mood Episode During Double Blind Period [ Time Frame: Period 2: 24 weeks or time of early termination ]

Secondary Outcome Measures:
  • Time to Discontinuation for Any Reason During Double Blind Period 2 [ Time Frame: Period 2: 24 weeks or time of early termination ]
  • Modified Time to Intervention for a Mood Episode (TIME) [ Time Frame: Period 2: Week 24 or time of early termination ]
  • Change From Baseline in Mania Rating Scale (MRS) by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 1 - 24 or time of early termination ]
  • Change From Baseline in Clinical Global Impression Severity (CGI-S) Score by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 1 - 24 or time of early termination ]
  • Clinical Global Impression - Improvement (CGI-I) Score by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 1 - 24 or time of early termination ]
  • Change From Baseline in Montgomery-Asberg Rating Scale (MADRS) Score by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 1 - 24 or time of early termination ]
  • Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 4 - 24 or time of early termination ]
  • Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Postive Scale by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 4 - 24 or time of early termination ]
  • Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Negative Scale by Visit During Double Blind Period [ Time Frame: Period 2: Weeks 4 - 24 or time of early termination ]

Arms Assigned Interventions
Experimental: Ziprasidone
Active treatment, double-blind, randomized arm
Drug: Ziprasidone Oral Capsule
Oral capsule formulation: Patients will be treated initially with open-label ziprasidone in the range of 40-80 mg BID for at least 10 weeks and up to 16 weeks. Patients who achieve a stable treatment regimen and whose symptoms stabilize for 8 consecutive weeks by Week 16 (Week 10 at the earliest) will be randomized. Patients randomized to ziprasidone will continue to receive the same stable treatment regimen achieved during the open-label treatment, ie, either 40 mg BID, 60 mg BID or 80 mg BID for up to 24 weeks of double-blind treatment.
Other Name: Geodon, Zeldox
Placebo Comparator: Placebo
Placebo treatment, double-blind, randomized arm
Drug: Placebo
Oral capsule formulation: Patients will be treated initially with open-label ziprasidone in the range of 40-80 mg BID (twice a day) for at least 10 weeks and up to 16 weeks. Patients who achieve a stable treatment regimen and whose symptoms stabilize for 8 consecutive weeks by Week 16 (Week 10 at the earliest) will be randomized. Patients randomized to placebo will be tapered off the open-label ziprasidone by 20 mg BID every 2 days (in a double-blinded manner) until they are completely off ziprasidone and are on matching placebo capsules for up to 24 weeks of double-blind treatment.
