About this study
Official title: Individualized Neuroimaging Biomarkers for Predicting rTMS Response in OCD
This study evaluates an accelerated schedule of theta-burst stimulation using a Transcranial Magnetic Stimulation (TMS) device for treatment-resistant Obsessive Compulsive Disorder (OCD). In a randomized fashion, half the participants will receive accelerated theta-burst stimulation at the dorsomedial prefrontal cortex (DMPFC), while half will receive accelerated theta-burst stimulation at the right orbitofrontal (rOFC) site.
Read the detailed description
Medications (SSRIs and D2 antagonists) and cognitive-behavioral therapy are the mainstays of treating OCD; however, many patients show only a partial response, and more than 25% of patients show no improvement with these treatments. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative, using powerful, focused magnetic field pulses to stimulate target brain areas. So far, at least two stimulation targets have consistent evidence of efficacy in OCD: the dorsomedial prefrontal cortex (DMPFC) and the orbitofrontal cortex (OFC). Patients often show a strong response to one target but not the other. It is not well understood why some patients respond, while others do not.
The investigators previously developed methods for discovering neurophysiological subtypes of depression based on resting state functional Magnetic Resonance Imaging (fMRI) measures of functional connectivity (RSFC) in relevant brain networks; diagnosing them in individual patients; and using them to predict individual differences in rTMS response. Subsequently, motivated by recent studies characterizing individual variability in the topology of these functional networks, the investigators have optimized methods for improving the accuracy of these predictions by accounting for individual variability, stabilizing the selection of treatment-predictive features, and increasing robustness in replication samples through regularization. Here, the investigators propose applying these methods to discover novel network-based subtypes of OCD and develop prognostic neuroimaging biomarkers for predicting differential treatment response to rTMS targeting the DMPFC or OFC, which could subsequently be tested in a randomized clinical trial.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Active bilateral DMPFCDevice
Participants in this arm will receive rTMS to bilateral DMPFC. The DMPFC will be targeted utilizing either Nexstim's eField neuronavigation system or Localite's neuronavigation system. Stimulation intensity will be standardized at 100% of resting motor threshold (RMT).
Active right-sided OFCDevice
Participants in this arm will receive rTMS to the right OFC. The right OFC will be targeted utilizing either Nexstim's eField neuronavigation system or Localite's neuronavigation system. Stimulation intensity will be standardized at 110% of resting motor threshold (RMT).
| Study group | Role | What they receive |
|---|---|---|
| bilateral DMPFC | Active comparator | This arm will receive intermittent theta-burst stimulation to bilateral DMPFC site. Receives: Device: Active bilateral DMPFC |
| right OFC | Active comparator | This arm will receive continuous theta-burst stimulation to the right OFC site. Receives: Device: Active right-sided OFC |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage change in Yale-Brown Obsessive-Compulsive Scale (YBOCS)
The YBOCS is a 10-item clinician-rated questionnaire that assesses the impact and severity of an individual's obsessive thoughts and compulsive behaviors. The minimum and maximum scores are 0 and 36, respectively, with higher score indicating greater severity.
Measured: Baseline (Pretreatment) to immediate post-treatment follow up
Secondary outcomes (1)
Percent change in the Obsessive-Compulsive Inventory-Revised (OCI-R)
The Obsessive-Compulsive Inventory-Revised (OCI-R) has 18 items. Each item can be scored on a 5 point scale from 0 to 4. Total score can range from 0 to 72, with higher scores indicating more severe OCD.
Measured: Baseline (Pretreatment) to immediate post-treatment follow up

This study evaluates an accelerated schedule of theta-burst stimulation using a Transcranial Magnetic Stimulation (TMS) device for treatment-resistant Obsessive Compulsive Disorder (OCD). In a randomized fashion, half the participants will receive accelerated theta-burst stimulation at the dorsomedial prefrontal cortex (DMPFC), while half will receive accelerated theta-burst stimulation at the right orbitofrontal (rOFC) site.

How can a doctor refer a patient or contact the research team?
Contact Nick Bassano, MSW (650-497-3933, nbassano@stanford.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage change in Yale-Brown Obsessive-Compulsive Scale (YBOCS) (time frame: Baseline (Pretreatment) to immediate post-treatment follow up). 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 NCT04286126, 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 18 Apr 2023.
