About this study

Official title: Longitudinal, Prospective Study to Examine the Brain-based Biomarkers of Response to Transcranial Magnetic Stimulation Treatment in Major Depressive Disorder

The overarching goal of this research program is to elucidate causal and directional neural network- level abnormalities in depression, and how they are modulated by an individually-tailored, circuit-directed intervention. By using concurrent TMS and EEG, the investigators can overcome a major limitation of EEG - the inability to demonstrate causality. Here, we plan to recruit patients with medication-resistant depression undergoing rTMS treatment. At multiple time points, we will perform TMS-EEG to investigate the excitability and connectivity profiles of brain networks and how they are modulated during treatment. This study aims to provide objective brain network measures that can predict and track clinical response to TMS treatment. Findings from this study will be utilized to develop a novel, personalized treatment protocol based on individual brain networks.

Read the detailed description

Goals of the study are as follows:

  • To evaluate the ability to predict and track brain network changes during TMS treatment for medication-resistant depression.
  • To develop quantitative tools that measure the connectivity and excitability of the brain using resting and single pulse TMS-EEG.
  • To determine the feasibility of recording EEG biomarkers in the clinic without disrupting clinical care.

Study groupRoleWhat they receive
rTMSrTMS will be delivered for 20 sessions over 4 weeks. Active 10 Hz rTMS will be delivered to the left DLPFC as assessed by either the 5cm rule or F3 site. Daily treatment regiments will last 36.5 minutes and rTMS will be delivered at 120% of the participant's motor threshold. Participants will be monitored during the rTMS sessions for adverse events and/or side effects.
Receives: Device: TMS

What is being measured

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

  1. TMS-EEG

    From pre- to post-treatment, improvement will be based on enhanced excitability and connectivity

    Measured: Up to 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Major Depressive Disorder and Depression, run by Stanford University 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 8 inclusion and 3 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 23 Jun 2022. 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?

TMS-EEG (time frame: Up to 3 months). 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 23 Jun 2022; AzTrials last refreshed its copy on 6 Nov 2026.
