About this study

Official title: Dichotic Listening as a Predictor of Placebo and Medication Response in Depression

Depressed patients will have hearing tests and then be treated with up to three treatments (i.e., Fluoxetine, Imipramine) until remitted, to see whether test results predict specific outcomes.

Read the detailed description

100 depressed patients will be tested with verbal and nonverbal dichotic tests, and then treated sequentially with Fluoxetine and Imipramine until remitted. Preferential hemisphere for auditory processing will be correlated with treatment outcome.

What is being measured

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

  1. Hamilton Depression Scale (HAM-D)

    The HAM-D is a commonly used measure of the severity of depression. While several versions exist consisting of different numbers of items, virtually all include the original 17. Each item is scored from on a 3 or 5 point scale (so, from 0-2 or 0-4), with 0 indicating the item is not present and the highest item score indicating it is present nearly all the time to the severest extent. Item scores are added to obtain a total HAM-D score. Minimum possible score is 0 (indicating none of the 17 items is present), maximal possible score is 52. By convention, scores of <=7 are accepted as indicating "remission" and scores that have decreased >= 50% from pre-treatment indicate positive "response". Higher scores indicate worse depression, while lower scores indicate milder depression or lack of depressive symptoms.

    Measured: 6 weeks

Secondary outcomes (1)
  1. Number of Participants With Positive Response as Assessed by the Clinical Global Impression -Global Improvement Scale (CGI-I)

    The CGI consists of two ratings: 1) Global Severity (CGI-S) and 2) Global Improvement (CGI-I), both having seven possible ratings, each from 1-7. Ratings on the CGI-S are: 1="No psychopathology" 2="Minimal psychopathology" 3="Mild psychopathology 4="Moderate psychopathology" 5="Moderately severe psychopathology" 6="Severe psychopathology" 7 "Extreme psychopathology". CGI-I ratings are rated for how the past week's psychopathology compares to the week immediately prior to start of treatment and includes: 1="Very much improved" 2="much improved" 3="minimally improved" 4="Unchanged" 5="minimally worse" 6="much worse" 7="very much worse". Scores on both thus range from 1-7 with lower scores indicating less psychopathology/greater improvement, respectively, and higher scores indicating more psychopathology/less improvement, respectively. We define "response" as a CGI-I of 1 or 2; "nonresponse" is all other ratings (i.e., CGI-I = 3 or higher.

    Measured: 6 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Fluoxetine and Imipramine in people with Major Depression and Dysthymia, run by New York State Psychiatric Institute at 1 site 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 2 inclusion and 12 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 30 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 15 May 2019). 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?

Hamilton Depression Scale (HAM-D) (time frame: 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00296725, which also lists 6 linked publications.

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 30 May 2019.
