About this study

Official title: Predictors of Response to Augmentation With Ziprasidone (Geodon®) in Major Depressive Disorder : A 13-week, Double-Blind, Placebo-Controlled, Cross-Over Trial

The primary outcome of this study is to determine if predictors of response can select a population of patients with MDD that is effectively treatable by augmentation with ziprasidone.

Major depressive disorder (MDD) is a broad category, including many forms of depressive illness, including those with only a single major depressive episode, those with episodic recurrence with intervening well states, those with chronic depressive/anxious states without intervening euthymia, and those with manic symptoms that do not meet threshold definitions of full mania/hypomania.

In this heterogenous, large diagnostic definition, important groups of patients do not appear to respond well to antidepressants, and, conversely, based on observational studies, may respond well to neuroleptics. These predictors of response have begun to be identified and may serve to better design studies of neuroleptics in depressive illnesses.

Among these predictors of response in MDD are clinical features that are more similar to bipolar illness than unipolar depression. These include a family history of bipolar disorder, antidepressant-induced mania, highly recurrent depressive episodes (>5), atypical depression, early age of onset of depression (< age 20), failure to respond to antidepressants, and antidepressant tolerance (initial response followed by later loss of response).

The investigators propose to use these predictors to pick out patients that are more likely to respond to Geodon for MDD. This will be the first RCT of these predictors of depressive response applied to neuroleptics.

Read the detailed description

This will be a three-site, block randomized (1:1 ratio) double-blind, placebo-controlled prospective cross-over study with 50 subjects. Patients will be randomized to receiving ziprasidone-washout-placebo or placebo- washout-ziprasidone for 13-weeks.

Primary and Secondary and safety outcomes: The primary outcome measure will be change from baseline Montgomery-Asberg Depression Rating Scale (MADRS) score to end of treatment. Safety outcomes will be determined by spontaneously reported adverse events on the case report form.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ziprasidoneDrug

    Also called Geodon

    Ziprasidone will be administered as a pill. The once-daily total daily dose will be 80-160 mg/d of ziprasidone. Dosing will begin at 20 mg BID with an escalation strategy based on target symptoms and tolerability, with a target dose range of 80-160 mg/d. Dose escalations will occur by increments of 20-40 mg weekly.

  • Sugar pillDrug

    Also called Placebo

    The once-daily total daily dose will be 80-160 mg/d of the sugar pill. Dosing will begin at 20 mg BID with an escalation strategy based on target symptoms and tolerability, with a target dose range of 80-160 mg/d. Dose escalations will occur by increments of 20-40 mg weekly.

What is being measured

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

  1. MADRS Improvement Over 6 Weeks

    Montgomery Asberg Depression scale improvement was assessed in two 6 week crossover periods.

    Minimum score on MADRS is 0, the maximum is 60. Higher scores represent a worse outcome, i.e., greater severity of depressive symptoms.

    Scores of about 20 and above are generally seen as consistent with being in a full major depressive episode.

    No subscales were used or combined.

    Measured: 13 weeks (Two 6 week periods plus a one week washout)

Secondary outcomes (1)
  1. Predictors of Bipolarity to Define the Study Population

    The specific bipolarity predictors in patients with MDD were assessed.

    Measured: 13 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ziprasidone and Sugar pill in people with Depression and Bipolar Disorder, run by Tufts Medical Center.

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 5 inclusion and 8 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 24 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 13 Feb 2017). 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?

MADRS Improvement Over 6 Weeks (time frame: 13 weeks (Two 6 week periods plus a one week washout)). 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 24 Feb 2017.
