About this study

Official title: Biological Predictors of Response to Antidepressants

This study will use pre-treatment positron emission topography and functional magnetic resonance imaging scans of the brain to predict the most effective antidepressant treatment for people with major depressive disorder.

Read the detailed description

Major depressive disorder (MDD) is characterized by a combination of symptoms that can interfere with a person's ability to work, study, sleep, eat, and enjoy activities that were once pleasurable. Studies have shown that as little as 50% to 60% of individuals with MDD may respond to the first antidepressant medication prescribed. Currently psychiatrists lack tools that allow them to select the treatment plan that is most likely to benefit a particular individual. Some of the chemical abnormalities in the brains of people with MDD are detectable on positron emission topography (PET) scans. There are distinct differences in the PET scans of people with MDD who respond to treatment with a selective serotonin reuptake inhibitor (SSRI), people with MDD who do not respond to SSRI treatment, and people who do not have MDD. This study will use pretreatment PET and functional magnetic resonance imaging (fMRI) scans of the brain to predict which antidepressants will be most effective in people with MDD. This may help to reduce the trial and error currently associated with antidepressant treatment.

We will perform pretreatment PET scans to quantify serotonin transporter (5-HTT) and serotonin 1A (5-HT1A) receptor in patients with major depressive disorder (MDD). All patients will then receive a standardized treatment protocol with a selective serotonin reuptake inhibitor (SSRI), escitalopram. If the patient does not remit, he or she will receive a selective norepinephrine reuptake inhibitor (NRI), desipramine. We hypothesize those patients with high pre and postsynaptic 5-HT1A BP and low 5-HTT BP in specific brain regions will not remit to a SSRI and will remit to a selective NRI. Finally, we will generate a predictive model of remission based on brain imaging outcome measures. Our overall goal is to reduce the trial and error associated with antidepressant treatment by using data from pre-treatment quantification of 5-HT1A receptors and 5-HTT to guide antidepressant treatment selection.

What participants receive

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

  • EscitalopramDrug

    Also called Lexapro

    Escitalopram will be administered at a dose of 10 mg daily for 4 weeks. If participants have not achieved response (greater than 50 % improvement in Hamilton Depression Rating Scale) by 4 weeks, the dose will be increased to 20 mg. Remission status is determined after an 8-week trial.

  • DesipramineDrug

    Also called Norpramin

    Subsequent to escitalopram trial, non-remitters will be offered pharmacotherapy with desipramine. Desipramine will be initiated at a dose of 50 mg and titrated according to a treatment manual, with monitoring of therapeutic blood levels. Remission status is determined after an 8-week trial.

What is being measured

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

  1. Remission of Depressive Symptoms

    Remission in this study is defined as both a ≥50% decrease in the 24-item Hamilton Depression Rating Scale (HDRS) Score and a final 24-item HDRS score <10. Remission of depressive symptoms was calculated for the 28 completers of the SSRI phase.

    Measured: Measured at Week 8

Secondary outcomes (2)
  1. Remission of Depressive Symptoms - Tricyclic Phase

    Participants who did not achieve remission during the SSRI phase advanced to the tricyclic phase of the study. Participants were treated with either desipramine or nortriptyline. Seven participants started the tricyclic phase. Four completed the tricyclic phase. The completers (n=4) were analyzed for remission status.

    Measured: Measured over 8 weeks

  2. Improvement in Scores on the Hamilton Depression Rating Scale - SSRI Phase

    Mean % improvement from baseline to end of treatment trial using the 24-item Hamilton Depression Rating Scale. Percent improvement of depressive symptoms was calculated for the 28 completers of the SSRI phase. The higher the score on the 24-item HDRS, the greater the depression severity. Minimum score on the scale is 0, and maximum score is 74. Subscales are not used for this analysis.

    Measured: Measured at Week 8

Questions about this trial

What is this clinical trial studying?

A study testing Escitalopram and Desipramine in people with Depression, 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 7 inclusion and 15 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 Mar 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jun 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?

Remission of Depressive Symptoms (time frame: Measured at Week 8). 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 NCT00456014, which also lists 1 linked publication.

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 Mar 2019.
