About this study

Study TRD subjects' resistance to at least 2 different antidepressants, we hypothesize that because of their significant depression and treatment resistant status they are most likely to exhibit BSMN pathway abnormalities.

Read the detailed description

Potential subjects will be identified during clinical visits. If a patient qualifies to participate in the study they will have to stop any antidepressants that they are taking to prepare for the use of MAOIs. After a two week washout period, subjects will have an fMRI and will be started on a MAOI. They will then be followed up for 8 weeks, which is routine and considered standard care.

What is being measured

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

  1. Brainstem Structural Connectivity (Sc)

    Localize BSMN and measure pathway Sc using diffusion imaging to differentiate between TRD and HC. BSMN can be localized using diffusion imaging, and pathways projecting from BSMN to known targets can be identified. Methods have been developed to localize these nuclei via a combination of diffusion imaging and anatomic imaging. We will identify these nuclei and track their projections to known targets, giving rise to the VTA-NAcc, VTA-AMYG, RN-AM and RN-sgACC pathways. Probabilistic fiber tracking between these nodes will be used to determine a measure of pathway strength.

    Measured: 2 years

  2. Brainstem Functional Connectivity (Fc)

    Measure BSMN pathway Fc to differentiate between TRD and HC. BSMN associated with different neuromodulators, e.g. the VTA and RN, will be associated with distinct functional networks which will be abnormal in TRD compared to HCs.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Treatment Resistant Depression, run by Kathryn O'Connor 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 13 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 18 Jun 2021. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Brainstem Structural Connectivity (Sc) (time frame: 2 years). The study lists 2 primary outcomes in all. 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 18 Jun 2021.
