About this study

Official title: An Open-Label, Flexible-Dose Trial of the Safety and Efficacy of Geodon in Non-Rapid-Cycling Bipolar II Patients With Major Depression

The purpose of this study is to evaluate the antidepressant effectiveness of Geodon for the treatment of patients diagnosed with Bipolar II disorder who are currently experiencing a major depressive episode.

Read the detailed description

Bipolar II disorder is largely unstudied, with much less known about its treatment in comparison to Bipolar I disorder. While established mood stabilizers treat and prevent subsequent episodes of hypomania, chronic or recurrent depressions are harder to treat or prevent. In general the treatment of depression in Bipolar II patients is often complicated and there is no clinical unanimity on what approaches to follow. Administration of proven antidepressants would seem most appropriate and are most often used, but their use often involves a number of difficulties. Among these are:

  • antidepressant efficacy is established for unipolar patients and extrapolation to Bipolar II patients is done without empirical support
  • Bipolar II patients can have switches into hypomanic behavior in response to antidepressant treatment given as monotherapy
  • even when mood stabilizers are concomitantly given, switches to hypomanic states still occur when antidepressants are added
  • antidepressants can cause cycle acceleration or induce rapid cycling when given to Bipolar II patients
  • non-response and loss of response are common reactions to antidepressants in Bipolar II patients

This study will also assess the tolerability of Geodon in the treatment of patients diagnosed with Bipolar II disorder who currently meet criteria for a Major Depressive Episode by examining the incidence of adverse events and the withdrawal rate due to adverse events.

This will be an open-label study. Subjects will be treated for 8 weeks with Geodon, starting at a dose of 20 mg twice per day. The maximum dose will be 60 mg twice per day. Subjects will have a physical exam, electrocardiogram (ECG), standard laboratory tests and a urine drug screen at the screen visit.

Efficacy evaluations will include 17-item Hamilton Depression Scale, Hamilton Anxiety Scale (HAM-D), Montgomery-Asberg Depression Rating Scale, and the Young Mania Rating Scale. Social outcome will be measured with a quality-of-life scale (the Q-LES-Q). Overall efficacy will be rated using the Clinical Global Severity and Improvement Scales.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Primary Efficacy Endpoint is the Comparison of Baseline and Week 8 Endpoint in the 17-item HAM-D Total Scores

    Hamilton Depression Rating Scale, measuring depression symptoms; possible total scores ranging from 0-54, with higher scores indicating greater severity of symptoms.

    Measured: Week 8

Secondary outcomes (6)
  1. Mean Change From Baseline in the Hamilton Anxiety Scale (HAM-A)

    Hamilton Anxiety Rating Scale, measuring anxiety symptoms; possible total scores ranging from 0-30, with higher scores indicating greater severity of anxiety.

    Measured: Week 8

  2. Mean Change From Baseline in the Montgomery-Asberg Depression Rating Scale

    Montgomery-Åsberg Depression Rating Scale, measuring depression symptoms; possible total scores ranging from 0-60, with higher scores indicating greater severity of depression.

    Measured: Week 8

  3. Percentage of Subjects With Clinical Global Inventory (CGI) Global Improvement Score of 1 or 2

    Clinical Global Impression of Improvement scale: one item, measuring overall improvement of illness; possible scores range from 1-7, with lower scores representing greater improvement.

    18 subjects (60%) were responders (defined as having a CGI-I scores of 1 or 2 at Week 8/study endpoint) by the end of the trial.

    Measured: Week 8

  4. Mean Change From Baseline in the CGI-Severity of Illness (CGI-S) Score at Study Endpoint

    Clinical Global Impression of Severity scale: one item, measuring overall severity of illness; possible scores range from 1-7, with higher scores representing greater severity of illness.

    Measured: Week 8

  5. Mean Change From Baseline in the Total Score of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q)

    Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) scale consists of 14 items; possible scores range from 14-70 with higher scores indicating greater quality of life and satisfaction.

    Measured: Week 8

  6. Mean Change From Baseline in the Total Score of the Beck Depression Inventory (BDI)

    Beck Depression Inventory, self-rated scale measuring depression symptoms; possible total scores ranging from 0-63, with higher scores indicating greater severity of depression.

    Measured: Week 8

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ziprasidone in people with Bipolar II Disorder and Major Depressive Episode, run by The Medical Research Network at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jun 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Primary Efficacy Endpoint is the Comparison of Baseline and Week 8 Endpoint in the 17-item HAM-D Total Scores (time frame: Week 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jun 2013.
