About this study

Official title: Transcranial Magnetic Stimulation to Augment Exposure and Response Prevention for Pediatric OCD

The goal of this clinical trial is to test transcranial magnetic stimulation (TMS) for improving the outcomes of Exposure with Response Prevention (ERP) in youth and young adults with Obsessive-Compulsive Disorder (OCD). Researchers will compare two groups: ERP with active ("real") TMS vs. ERP with sham ("fake") TMS. The first phase of this study found that active TMS+ERP normalized functioning in brain circuits that contribute to compulsive behavior. This second phase will test whether TMS-induced brain changes lead to improvements in OCD symptom severity. Participants will:

  • Complete clinical interviews, questionnaires, and computerized tasks
  • Complete two MRIs (brain scans)
  • Receive daily TMS followed by ERP for two weeks (10 sessions)
Read the detailed description

Pediatric OCD is a public health problem and many remain symptomatic even after receiving efficacious treatments. The success of exposure and response prevention (ERP), a first-line behavioral treatment, depends on the ability to refrain from compulsions during exposure tasks. Improving this "therapy critical behavior" is a potentially important strategy for ERP augmentation. Repetitive transcranial magnetic stimulation (rTMS) can be leveraged to stimulate healthier functioning of brain circuits underlying therapy critical behaviors. The overall objective of this project is to test whether augmenting ERP with rTMS over cortical nodes of select cortico-striatal circuits implicated in compulsivity can normalize connectivity and enhance response prevention in youth and young adults with OCD. This project will use a masked RCT design to test whether ERP+TMS engages hypothesized circuits involved in compulsivity and whether this leads to clinical improvement. Youth ages 12-21 years with OCD will complete a full course of ERP plus randomly assigned TMS regimens of sham or continuous theta burst stimulation (cTBS) to the presupplementary motor area (pSMA; n=30 per group).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transcranial Magnetic Stimulation: continuous theta burst to pre supplementary motor areaDevice

    Also called TMS, neuromodulation, cTBS

    TMS will be delivered over the pre supplementary motor area (preSMA) using a continuous bursting pattern

  • Transcranial Magnetic Stimulation: ShamDevice

    Also called TMS, neuromodulation

    Sham stimulation will use the Magstim sham air-cooled coil, which produces auditory signals and appears identical to an active coil but contains a mu-metal shield that diverts the majority of the magnetic flux such that a minimal (<3%) magnetic field is delivered to the cortex

  • Exposure with Response PreventionBehavioural

    Also called ERP, Exposure Therapy, Cognitive Behavioral Therapy, CBT

    ERP will be delivered daily, immediately following TMS

What is being measured

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

  1. Functional Magnetic Resonance Imaging (fMRI): connectivity of the pSMA-DLS circuit

    correlation coefficient representing resting state connectivity between presupplementary motor area (pSMA) and dorsolateral striatum (DLS)

    Measured: two weeks (post-treatment)

  2. Observed Compulsive Behavior

    Duration of time during which compulsions are observed during ERP sessions

    Measured: two weeks

  3. Child/Adult Yale-Brown Obsessive Compulsive Inventory

    Independent-Evaluator (IE) rated measure of OCD symptom severity. Rated on 0 (no symptoms) to 40 (most extreme symptoms) scale

    Measured: six weeks (1-month follow-up)

Secondary outcomes (1)

  1. Clinical Global Impressions Scale-Improvement

    Independent-Evaluator (IE) rated measure of clinical improvement. Rated on 1 (very much improved) to 7 (very much worse) scale

    Measured: six weeks (1-month follow-up)

Questions about this trial

What is this clinical trial studying?

A study testing Transcranial Magnetic Stimulation: continuous theta burst to pre supplementary motor area and Exposure with Response Prevention in people with Obsessive Compulsive Behavior, run by Bradley Hospital at 2 sites 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 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What does the primary outcome measure?

Functional Magnetic Resonance Imaging (fMRI): connectivity of the pSMA-DLS circuit (time frame: two weeks (post-treatment)). The study lists 3 primary outcomes in all. 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 NCT07859683.
