TMS for Improving Response Inhibition in Adolescents With OCD

January 7, 2025 updated by: Kristen Benito, Bradley Hospital
The study will examine whether inhibition of the pre-supplementary motor area (pSMA) using transcranial magnetic stimulation (TMS) normalizes activity in pSMA-connected circuits, improves response inhibition, and reduces compulsions in adolescents with OCD.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age 13-18 years

  • Right-handed
  • If taking psychotropic medications, these have been stable for > 6 weeks and are expected to remain stable for the approximately 3-week study protocol
  • If currently in psychotherapy, symptom improvement has plateaued (no improvement in the past 6 weeks and symptoms expected to remain stable for the approximately 3-week study protocol)

Exclusion Criteria:

  • • Medical conditions contraindicated for TMS or EEG, including history of intracranial pathology, increased intracranial pressure, epilepsy or seizures, traumatic brain injury, brain tumor, stroke, implanted medical devices, possible pregnancy (female of childbearing age not using effective contraception), or any other serious medical condition (note that medical history will be reviewed by a study physician prior to TMS administration)

    • Patient is a ward of the state
    • Family history of epilepsy
    • History of syncope

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: TMS at visit 1, Sham at visit 2
At visit 1, participants will receive active TMS using continuous theta burst over the preSMA. At Visit 2, participants will receive sham (fake) TMS in the same location.
Device: Transcranial Magnetic Stimulation
All teens will receive active TMS; they will be randomly assigned to receive active TMS at either visit 1 or visit 2 (order counterbalanced)
Other: Sham at visit 1, TMS at visit 2
At visit 2, participants will receive active TMS using continuous theta burst over the preSMA. At Visit 1, participants will receive sham (fake) TMS in the same location.
Device: Transcranial Magnetic Stimulation
All teens will receive active TMS; they will be randomly assigned to receive active TMS at either visit 1 or visit 2 (order counterbalanced)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Response Time on Stop Trials of the Stop Signal Task
Time Frame: Change from pre (within 1 hour before) to post (within 1 hour after) intervention
Computerized task, where shorter response time (in milliseconds) indicates better performance
Change from pre (within 1 hour before) to post (within 1 hour after) intervention
Change in Frontocentral P3 Amplitude on Electroencephalogram (EEG)
Time Frame: Change from pre (within 1 hour before) to post (within 1 hour after) intervention
Electroencephalogram (EEG) measured amplitude on successful stop trials of the stop signal task (SST). Calculated by averaging the epochs of successful stop trials time-locked to the stop signal from the midline electrode (Cz).
Change from pre (within 1 hour before) to post (within 1 hour after) intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Self-report Symptom Question
Time Frame: post (within 1 hour after) intervention
Self-rated compulsions on a single-item 0-5 scale, where higher scores indicate more compulsions
post (within 1 hour after) intervention
