Trial summary

The purpose of this study is to determine whether vilazodone is more effective than citalopram for the treatment of anxious depression. We will use neuroimaging to see whether there are changes in the brains of patients receiving the drug vilazodone that are different from those of citalopram. Read more about this study

About this study

The purpose of this study is to determine whether vilazodone is more effective than citalopram for the treatment of anxious depression. We will use neuroimaging to see whether there are changes in the brains of patients receiving the drug vilazodone that are different from those of citalopram. These changes may show that vilazodone affects the brain differently than most other kinds of standard antidepressant medications.

Read the detailed description

This study proposes to utilize recent advances in magnetic resonance spectroscopy (MRS) techniques that permit reliable measurement of Glu in humans (9) to examine whether Vilazodone and citalopram exert differential effects on Glutamatergic neurotransmission in the ACC of anxious unipolar depressed patients. Functional connectivity as measured by Blood Oxygen Level Dependent (BOLD) MRI will be assessed to determine the relationship between the change in connectivity and the change in Glu levels with treatment. We also propose to examine, in an exploratory fashion, the relative effect of the two drugs on BOLD activation in the insula cortex.

What is being measured

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

  1. Glutamate Levels

    Our hypothesis that Vilazodone will increase ACC glutamate levels more than Citalopram will be addressed using a repeated measures linear regression model with ACC glutamate level as the outcome and drug (Vilazodone or Citalopram) and drug x scan time (baseline or follow-up) interaction as predictors.

    Measured: Week 0 and Week 4

Secondary outcomes (1)
  1. Functional Connectivity

    Our hypothesis that Vilazodone will decrease functional connectivity more than Citalopram will be addressed using a repeated measures linear regression model with functional connectivity correlation as the outcome and drug (Vilazodone or Citalopram) and drug x scan time (baseline or follow-up) interaction as predictors.

    Measured: Week 0 and Week 4

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Vilazodone and Citalopram in people with Major Depressive Disorder and Anxiety, run by Massachusetts General Hospital 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 6 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: withdrawn, as of the sponsor's last update on 8 Nov 2016. 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 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Glutamate Levels (time frame: Week 0 and Week 4). 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 8 Nov 2016.
