About this study

The purpose of this study is to develop repetitive transcranial magnetic stimulation (rTMS) as a potential treatment for pain in individuals on prescription opioid medication. Repetitive TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether 10 days of rTMS over the prefrontal cortex can produce a reduction in perception of pain and the desire to use opiates. TMS has been approved by the FDA as an investigational tool as well a therapy for depression.

Read the detailed description

Individuals between the ages of 18 and 65 with current (past 3 months) prescription opioid use and chronic pain are being recruited. Participants will be screened on the telephone for major inclusion/exclusion criteria. Individuals meeting inclusion criteria based on the screening assessment will be set up for an appointment in the clinic. Participants will be instructed not to use alcohol, prescription opioids, or any other drugs on the day of their appointment. All study procedures will take place at the 30 Bee Street location of the Brain Stimulation Lab (BSL). The protocol contains 1 screening visit, 10 TMS visit, and 2 follow up visits. Individuals that are eligible following the screening visit will be randomized to receive real or sham TMS.

On each TMS visit participants will undergo a single 20-minute session of 10Hz real or sham rTMS (on-time=5 secs, off-time=10 secs) at up to 110% of resting motor threshold using a MagVenture MagPro TMS machine.

Primary outcomes will be:

  1. change in pain sensitivity levels in the pain assessment task and
  2. change in levels of opiate craving.

The investigators will use analysis of variance models with group (real rTMS vs. sham) as the between-subjects factor and time (pre- to post-TMS) as a within-subject factor. The investigators will test the hypothesis that rTMS will result in significantly lower levels of reported pain sensitivity and craving, as compared to sham. Blind interim analyses of the data will be conducted when 50% of the sample has been accrued.

What participants receive

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

  • Real Transcranial Magnetic StimulationDevice

    Also called TMS

    Transcranial magnetic stimulation (TMS) is a minimally invasive brain stimulation technology that can focally stimulate the brain of an awake individual. A localized pulsed magnetic field transmitted through a figure-8 coil (lasting only microseconds) is able to focally stimulate the cortex by depolarizing superficial neurons, which induces electrical currents in the brain. TMS pulses that are delivered repetitively and rhythmically are referred to as repetitive TMS (rTMS). In this study TMS is being delivered with the MagVenture MagPro B60 coil.

  • Sham Transcranial Magnetic StimulationDevice

    The MagVenture MagPro system has an integrated active sham that passes current through two surface electrodes placed on the skin beneath the B60 coil.

What is being measured

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

  1. Thermal pain threshold

    Quantitative Sensory Testing will be used to measure each participant's thresholds for sensory detection of heat, painfulness, and tolerance. The investigators will test the hypothesis that Real TMS has a larger effect on thermal pain threshold following 10 days of TMS than sham TMS.

    Measured: Day 1 versus Day 10

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Real Transcranial Magnetic Stimulation in people with Pain, Chronic and Pain Acute, run by Medical University of South Carolina 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 2 inclusion and 6 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: finished, as of the sponsor's last update on 19 Sep 2024. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Thermal pain threshold (time frame: Day 1 versus Day 10). 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 19 Sep 2024.
