Arm Intervention/treatment
Experimental: Open Drug: Ziprasidone oral capsules
Study medications will include oral ziprasidone capsules of 20 mg, 40 mg, 60 mg, and 80 mg strength. Subjects will be dosed daily for 26 weeks using a flexible dose design with a minimal dose range of 20mg bid to a maximum dose range of 80 mg bid .



Primary Outcome Measures :
  1. Young Mania Rating Scale (YMRS) Total Score Change From Baseline [ Time Frame: baseline and 26 Weeks; 26 Weeks Last Observation Carried Forward (LOCF) ]
    YMRS: 11-item instrument with scales 0 (normal) to 4 (highest abnormal)for 7 items and 0 (normal) to 8 (highest abnormal) for 4 items. Total possible 0 - 60. Baseline is from parent study A1281132.

  2. Clinical Global Impression of Severity (CGI-S) Change From Baseline [ Time Frame: baseline and 26 Weeks; 26 Weeks LOCF ]
    CGI-S Scale:standardized assessment tool to rate severity of subject's illness; assesses investigator's impression of subject's current illness state. Change: score at observation minus score at baseline. Score: 1 (not ill at all) to 7 (among most extremely ill). Baseline = last available observation from parent double-blind study(A1281132).

  3. Incidence of Lab Abnormalities [ Time Frame: Week 26 ]
    number of subjects with an abnormal lab value for those parameters with 5% or greater incidence of abnormality.

  4. Change in Low-Density Lipoprotein (LDL) Cholesterol and Fasting Cholesterol [ Time Frame: Week 6, Week 26 ]
    Mean Change: lab value at observation minus lab value at baseline.

  5. Change in Hormones [ Time Frame: Week 6, Week 26 ]
    Mean Change: lab value at observation minus lab value at baseline

  6. Mean Change From Baseline in Supine Systolic Blood Pressure [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  7. Mean Change From Baseline in Supine Diastolic Blood Pressure [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  8. Mean Change From Baseline in Supine Pulse Rates [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  9. Mean Change From Baseline in Standing Systolic Blood Pressure [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  10. Mean Change From Baseline in Standing Diastolic Blood Pressure [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  11. Mean Change From Baseline in Standing Pulse Rates [ Time Frame: Week 1 through Week 26 ]
    Mean Change: vital sign value at observation minus vital sign value at baseline

  12. Mean Change From Baseline for Body Weight [ Time Frame: Week 6, Week 26 ]
    Mean change; body weight value at observation minus body weight value at baseline.

  13. Mean Change From Baseline for Body Mass Index (BMI) Z-Score [ Time Frame: Week 6, 26, early termination ]
    mean change in body weight BMI -Z score calculated by subtracting median reference value of the population from observed value and dividing by standard deviation of reference population (kg/m squared). 0=no change

  14. Body Mass Index (BMI) Z-score Frequency [ Time Frame: Week 6 ]
    change in body weight BMI -Z score calculated by subtracting median reference value of the population from observed value and dividing by standard deviation of reference population (kg/m squared). 0=no change

  15. Body Mass Index (BMI) Z-score Frequency [ Time Frame: Week 26 ]
    change in body weight BMI -Z score calculated by subtracting median reference value of the population from observed value and dividing by standard deviation of reference population (kg/m squared). 0=no change

  16. Mean Change From Baseline for QTcF Intervals [ Time Frame: Baseline to Week 26 (end of study) ]
    QT intervals (observed in an electrocardiogram)corrected using Fridericia's formula (QTcF). Mean change: mean change of observation minus baseline. Baseline: last available observation in the parent double-blind study.

  17. Frequency of Largest Categorical Increases in QTcF for Males [ Time Frame: Week 26 (end of study) ]
    QT intervals (observed in an electrocardiogram) corrected with Fridericia's Formula (QTcF). Number of subjects with corresponding categorical increase in QTcF.

  18. Frequency of Largest Categorical Increases in QTcF for Females [ Time Frame: Week 26 (end of study) ]
    QT interval (observed in an electrocardiogram) corrected using Fridericia Formula (QTcF). Number of subjects with corresponding categorical increase in QTcF.

  19. Frequency of Largest Categorical Increases in QTcF - All Subjects [ Time Frame: Week 26 (end of study) ]
    QT intervals (observed in an electrocardiogram)corrected using Fridericia Formula (QTcF). Number of subjects with corresponding categorical increase in QTcF.
