Study summary

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.

Inclusion criteria

Adults meeting (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria for Bipolar I Disorder (currently with manic or mixed symptoms)

Exclusion criteria

Exclusion Criteria:

Ultra rapid cyclers and subjects with significant cardiovascular disease including history of and/or congenital long QT syndrome

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Interventions

  • DrugPlacebo

    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.

  • 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.

What researchers measure

Primary outcomes

  1. Time to Intervention for a Mood Episode During Double Blind Period

    Time to Intervention for Mood Episode (TIME) while on randomized drug after at least 8 weeks of symptom reduction on open-label ziprasidone plus mood stabilizer. Mood episode considered to have occurred and subject discontinued if one or more of the following: Investigator (INV) decides discontinuation is in best interest of subject; loss of effect and/or change to treatment regimen (INV judgment); subject hospitalized for disease under study; Mania Rating Scale (MRS) and/or Montgomery-Asberg Rating Scale (MADRS) rating is ≥18 for 2 consecutive visits scheduled no more than 10 days apart.

    Time frame: Period 2: 24 weeks or time of early termination

Secondary outcomes

  1. Time to Discontinuation for Any Reason During Double Blind Period 2

    Key Secondary endpoint is time to discontinuation for any reason. Profile of patients remaining in the trial over time.

    Time frame: Period 2: 24 weeks or time of early termination

  2. Modified Time to Intervention for a Mood Episode (TIME)

    Time to intervention for a mood episode or time to discontinuation for treatment related adverse events, or death due to drug, or death due to disease. Mood episode considered to have occurred and subject discontinued if one or more of the following: Investigator (INV) decides discontinuation is in best interest of subject; loss of effect and/or change to treatment regimen (INV judgment); subject hospitalized for disease under study; Mania Rating Scale (MRS) and/or Montgomery-Asberg Rating Scale (MADRS) rating is ≥18 for 2 consecutive visits scheduled no more than 10 days apart.

  6. Change From Baseline in Montgomery-Asberg Rating Scale (MADRS) Score by Visit During Double Blind Period

    Baseline for Period 2 is the last observation in Period 1 to the start of Period 2. MADRS is 10-item instrument measuring depression: scales from 0=Normal to 6 = most abnormal.

    Time frame: Period 2: Weeks 1 - 24 or time of early termination

  7. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score by Visit During Double Blind Period

    Baseline for Period 2 is the last observation in Period 1 to the start of Period 2. Positive and Negative Syndrome Scale Total Score is 30-item scale measuring severity of psychopathology (16 items), positive symptoms (7 items) and negative symptoms (7 items); scale from 1 (absent) to 7 (extreme)

    Time frame: Period 2: Weeks 4 - 24 or time of early termination

  8. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Postive Scale by Visit During Double Blind Period

    Baseline for Period 2 is the last observation in Period 1 to the start of Period 2. Positive Scale is 7-items derived from PANSS; 1 (absent), 2 (minimal) to 7 (extreme).

    Time frame: Period 2: Weeks 4 - 24 or time of early termination

  9. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Negative Scale by Visit During Double Blind Period

    Baseline for Period 2 is the last observation in Period 1 to the start of Period 2. Negative Scale is 7 items derived from PANSS; scale is 1 (absent) to 7 (extreme).

Limitations and caveats
This is a maintenance of effect design using a survival analysis methodology. In such a design it may be difficult to interpret timepoint by timepoint treatment group comparisons in MRS, CGI-S, CGI-I, MADRS, and PANSS.

Participant flow

Trial intended to be outpatient trial. Patients hospitalized at the screening visit due to disease under study were to be stable enough for outpatient status within approximately 5 days.
