NCT ID NCT05008198

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is testing whether an EEG (a simple brain wave recording) can predict which veterans with treatment-resistant depression will improve with transcranial magnetic stimulation (TMS). About 266 veterans will get EEG scans before, during, and after TMS treatment. The goal is to find a reliable brain signal that tells doctors early on if TMS is working for a particular person.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Transcranial Magnetic Stimulation (TMS)
What this could lead to
If successful, this could help doctors predict who will respond to TMS for depression, saving time and improving treatment choices.
What could go wrong
This is an observational study, not a treatment trial. It aims to find a biomarker, not to prove TMS works. Results may not apply to all patients.

Participants

266 people

The number who actually took part.

Started

Aug 2021

Expected to finish

Sep 2026

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Veterans with major depressive disorder (MDD) participating in the VA Clinical TMS Pilot Program. Given the complex nature of the Veteran population, the primary diagnosis of MDD may be comorbid with other disorders, including post-traumatic stress disorder (PTSD).

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Veterans participating in the VA TMS Pilot Program age 18 years or older * Able to provide written informed consent to participate in the EEG portion of this study and to allow linking such data to data collected as part of the TMS Pilot Program * Diagnosis of MDD based on DSM-5 criteria and be currently depressed despite prior treatment with at least one adequate antidepressant treatment * Receiving stable doses of psychiatric medications (no dose changes for \>4 weeks prior to study entry), in stable psychotherapy, or receiving no psychiatric medications and/or psychotherapy Exclusion Criteria: * History of seizure disorder * Known structural or neurologic abnormalities present or close to the treatment site that would increase risk of seizure * History of brain surgery * History of recent traumatic brain injury (within 6 months) or any history of moderate to severe traumatic brain injury * Clinical evidence of severe or uncontrolled alcohol or substance use disorders within three months * Active withdrawal from alcohol or other substances of abuse * Implanted metal device in the head that would increase the risk of TMS * Metal in the head that would increase the risk of TMS * Current psychosis
