Biomarker-guided rTMS for Treatment Resistant Depression (BioTMS)

February 24, 2026 updated by: Weill Medical College of Cornell University

Efficacy of Biomarker-guided rTMS for Treatment Resistant Depression

Repetitive transcranial magnetic stimulation (rTMS) is a treatment for depression. The investigators are continuing to learn how to optimize outcomes from rTMS treatment. The purpose of this research project is to use brain network connectivity patterns as measured by resting state functional magnetic resonance imaging (fMRI) to confirm a way to optimize the use of rTMS to treat depression. In addition, the study aims to gain a better understanding of how rTMS influences brain networks.

Detailed Description

Major depressive disorder (MDD) is a leading cause of global disability, and approximately 30% of MDD patients are resistant to antidepressant pharmacotherapy. Repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) is an FDA-cleared intervention with proven efficacy in treatment-resistant depression, but only 30-40% of these patients achieve remission after a single course. Other studies have shown that rTMS targeting the dorsomedial prefrontal cortex (DMPFC) is comparably effective, but biomarkers for informing target site selection do not exist. Diagnostic heterogeneity has been an obstacle to biomarker discovery efforts. Recently, we developed and validated an approach to diagnose four novel MDD subtypes or "biotypes' defined by resting state functional connectivity (RSFC) patterns and predicting differing antidepressant responses at the individual level to rTMS. This pivotal trial will test a novel, biotype-guided treatment selection strategy motivated by the hypothesis that an individual patient's likelihood of responding to left DLFPC vs.DMPFC rTMS is determined in part by individual differences in 1) the degree to which their symptoms are driven by dysfunction in specific cerebral network targets comprising Valence Systems; and 2) the degree to which dysfunction in those targets can be modulated by stimulating the left DLPFC or DMPFC. Subjects (N=348; 174 from this site) will be randomized to receive a) biotype-guided rTMS targeting the DMPFC or left DLPFC; b) to a disconfirmation arm receiving rTMS targeting the opposite site; and c) to a third arm receiving FDA-cleared, standard-of-care rTMS targeting the left DLFPC, regardless of biotype. The dosage and method of delivery of rTMS for all arms are as follows: intermittent theta burst stimulation (iTBS) will be delivered at 120% of the resting motor threshold. It will be administered in triplet 50 Hz bursts, repeated at 5 Hz with a duty cycle of 2 s on and 8 s off, for a total of 600 pulses per session and a total duration of 3 min 9 s. All patients will be assessed before and after treatment on a battery of fMRI, behavioral, and clinical assessments. The primary goal is to confirm the efficacy of a novel RSFC biomarker-guided approach to differential treatment selection in treatment resistant depression.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

In accordance with NIH policy we will share our data via the National Database for Clinical Trials related to Mental Illness (NDCT). NDCT is a secure data platform that will allow us to share research data and tools from our analysis of resting-state fMRI data, task-based fMRI data, and fMRI-guided rTMS data. Specifically, data to be shared will include de-identified neuroimaging scans and rTMS targeting data, in addition to phenotypic data such as demographics, diagnosis, treatment history, and anonymized, item-level responses to clinical and cognitive assessments. These data will then be made available through the NDCT, and NIH-funded repository that ensures that data are secure and shared in accord with applicable NIH regulations.

IPD Sharing Time Frame

Raw data (e.g., MRI data and assessment responses) will be deposited on the NDCT every six months (January 15 and June 15 of each year of the award period), in accordance with NIH policy for use of the NDCT in clinical trials research. Curated data will be uploaded annually beginning in the third year of the project.

IPD Sharing Access Criteria

The data may be shared with researchers at institutions with a Federal Wide Assurance, who will be able to gain access to NDCT data by submitting a data access request, in line with NDCT policies.
