About this study

Official title: Neurocircuitry of OCD: Effects Of Modulation

The purpose of this study is to test the effects of non-invasive neuromodulation, transcranial magnetic stimulation on brain function in individuals with obsessive-compulsive disorder (OCD). This study is focused on the mechanism(s) by which brain stimulation might change the functioning of regions implicated in OCD, and thereby inform possible future therapeutic uses.

What participants receive

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

  • Transcranial Magentic StimulationDevice

    Also called Continuous Theta Burst Stimulation (cTBS)

    This is a form of mild brain stimulation delivered noninvasively. The device delivers pulses of magnetic energy through a coil placed on the scalp. The treatment takes 41 seconds, and takes place for ten sessions, Monday through Friday, over the course of two weeks

Study groups in NCT02704117
Study groupRoleWhat they receive
Transcranial Magnetic StimulationExperimentalTranscranial Magnetic Stimulation applied over the pre-supplementary motor area (pSMA), for ten sessions, Monday through Friday, over the course of two weeks.
Receives: Device: Transcranial Magentic Stimulation

What is being measured

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

  1. Change in activation of pre-supplementary motor area/dorsal anterior cingulate cortex (pSMA/dACC) on functional magnetic resonance imaging (fMRI) during the Multi-Source Interference task (MSIT)

    Measured: Baseline and 6 months

Secondary outcomes (1)
  1. Change in Yale-Brown Obsessive Compulsive Scale (Y-BOCS)

    Measured: Baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Transcranial Magentic Stimulation in people with Obsessive-Compulsive Disorder, run by Butler Hospital at 1 site 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 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in activation of pre-supplementary motor area/dorsal anterior cingulate cortex (pSMA/dACC) on functional magnetic resonance imaging (fMRI) during the Multi-Source Interference task (MSIT) (time frame: Baseline and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 Dec 2023.
