| Safety and Maintenance of Effect of Ziprasidone Plus a Mood Stabilizer in Bipolar I Disorder (Manic or Mixed) |
| 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 |
| 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. |

| Phase 3 |
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment |
- Bipolar Mania
- Bipolar Disorder
|
- 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.
- 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.
