About this study
This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In a double-blind, randomized, sham-controlled fashion, half the participants will receive accelerated theta-burst stimulation while half will receive sham treatment.
Read the detailed description
Repetitive transcranial magnetic stimulation (rTMS) is an established therapy for treatment-resistant depression. The approved method for treatment is 10Hz stimulation for 40 min over the left dorsolateral prefrontal cortex (L-DLPFC). This methodology has been effective in real world situations. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session, 5 days per week, for 4-8 weeks). Recently, we have pursued modifying the treatment parameters to reduce treatment times with an accelerated treatment paradigm with great preliminary success. This study aims to further study our accelerated protocol and examine changes in neuroimaging biomarkers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Active TBS-DLPFCDevice
Participants in the active stimulation group will receive intermittent TBS to left DLPFC. The L-DLPFC will be targeted utilizing the Soterix Neural Navigator neuronavigation system. Stimulation intensity will be standardized at 90% of RMT and adjusted to the skull to cortical surface distance (see Nahas 2004).
Stimulation will be delivered to the L-DLPFC using a MagPro TMS system (MagVenture, Denmark).
Sham TBS-DLPFCDevice
The parameters in the sham arm will be as above with the internal randomization of the device internally switching to sham in a blinded fashion.
| Study group | Role | What they receive |
|---|---|---|
| Active TBS-DLPFC | Active comparator | The active group will receive theta-burst TMS stimulation. Receives: Device: Active TBS-DLPFC |
| Sham TBS-DLPFC | Sham comparator | The sham group will receive sham theta-burst TMS stimulation. Receives: Device: Sham TBS-DLPFC |
What is being measured
The primary outcome is the main question the study is designed to answer.
Rates of remission one month after treatment in the Montgomery-Åsberg Depression Rating Scale (MADRS) score.
The Montgomery-Åsberg Depression Rating Scale (MADRS), is a ten item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60.
Remission is defined as MADRS ≤10.
Measured: Baseline, 1-month.
Secondary outcomes (1)
Rates of response one month after treatment in the Montgomery-Åsberg Depression Rating Scale (MADRS) score.
The Montgomery-Åsberg Depression Rating Scale (MADRS), is a ten item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60.
Response is defined as a reduction of >/=50% of MADRS baseline score.
Measured: Baseline, 1-month.

Questions about this trial
What is this clinical trial studying?
A study testing Active TBS-DLPFC in people with Treatment Resistant 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 18 inclusion and 18 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: under way, not looking for participants, as of the sponsor's last update on 6 May 2025. 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. Some participants in this study may receive a placebo. 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?
This study is still under way. Results are not available in the source record yet.
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?
Rates of remission one month after treatment in the Montgomery-Åsberg Depression Rating Scale (MADRS) score. (time frame: Baseline, 1-month.). 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 NCT04739969, which also lists 16 linked publications.
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 6 May 2025.
