About this trial

The goal of this clinical trial is to compare different forms of 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 three groups: ERP with one of two different active ("real") forms of TMS vs. ERP with sham ("fake") TMS. The main questions this study aims to answer are: 1) whether TMS normalizes functioning in brain circuits that contribute to compulsive behavior, and 2) whether TMS reduces compulsions during ERP. 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)

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Between the ages of 12 and 21 years.

Presence of OCD, as indicated by a score of > 16 on the Children's Yale-Brown Obsessive Compulsive Scale, indicating moderate or greater OCD symptoms.

Presence of motor compulsions on CY-BOCS compulsion checklist

English fluency to ensure comprehension of informed consent and study measures and instructions.

Disqualifiers

Decline to provide informed consent.

Has a personal history, or a family history in a first-born relative, of any medical or psychiatric disorder, disease, condition, injury, symptoms or circumstance that, in the opinion of the principal investigator, may: (1) impact the risk profile of TMS; (2) reduce the subject's ability to fulfill the study requirements as per protocol; or (3) adversely impact the integrity of the data or the validity of the study results." Some examples include: epilepsy or seizure disorder(s), bipolar disorder or any psychiatric disorder associated with a risk of mania, intracranial pathology, traumatic brain injury, brain tumor, stroke, implanted medical devices or metallic objects in the head, or moderate-severe heart disease

Pregnant according to the medical history or a urine pregnancy test; and menstruating females who are heterosexually active and not using a highly effective form of contraception (tubal ligation, FDA-approved hormonal contraceptive, or an IUD)

Inability to undergo MRI.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Transcranial Magnetic Stimulation: intermittent theta burst to dorsolateral prefrontal cortex

    Device

    TMS will be delivered over the dorsolateral prefrontal cortex (dlPFC) using an intermittent bursting pattern

  • Exposure with Response Prevention

    Behavioral

    ERP will be delivered daily, immediately following TMS

  • Transcranial Magnetic Stimulation: Sham

    Device

    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

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

    Device

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

Treatment groups

60 Participants
are divided into 3 treatment groups
Group A: ERP+iTBSExperimental treatment 2 interventions
Group B: ERP+cTBSExperimental treatment 2 interventions
Group C: ERP+ShamActive comparator 2 interventions

Trial outcomes

Primary outcomes

1

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

z-score representing change in resting state connectivity between presupplementary motor area (pSMA) and dorsolateral striatum (DLS)

Time frame
change from baseline at two weeks (post-treatment)
2

Functional Magnetic Resonance Imaging (fMRI): connectivity of the dlPFC-DMS circuit

z-score representing change in resting connectivity between dorsolateral prefrontal cortex and dorsomedial striatum (DMS)

Time frame
change from baseline at two weeks
3

Observed Compulsive Behavior

Mean proportion of time during which compulsions are observed during ERP sessions

Time frame
two weeks

Secondary outcomes

1

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

Time frame
change from baseline at two weeks (post-treatment)
