About this study

Official title: Evaluation of Active Emotional State on the Efficacy of Transcranial Magnetic Stimulation

The primary goal of this study is to elucidate the impact of disorder provocation on the efficacy of TMS for the treatment of BED. In order to meet this objective, the investigators propose to evaluate this relationship in using a crossover study. Secondary objectives of this study include determining whether TMS with or without BED symptom provocation has effects in altering neurophysiology as detected by fMRI.

Read the detailed description

Current literature has demonstrated that transcranial magnetic stimulation (TMS) targeting the dorsolateral prefrontal cortex (DLPFC) has some efficacy in treating binge eating disorder. The investigators believe that TMS may be beneficial in the treatment of binge eating disorder. The purpose of this study is to determine whether TMS has efficacy for binge eating disorder and if symptom provocation affects treatment. This study will be conducted as a pilot study in the Keck Hospital clinics. 32 adult patients with a clinical diagnosis of binge eating disorder will be recruited.

What participants receive

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

  • TMS followed by Sham TMSDevice

    double blinded crossover schedule in which participants will undergo TMS and assessment in one visit, followed by sham-TMS and assessment the next visit.

  • Sham TMS followed by TMSDevice

    double blinded crossover schedule in which participants will undergo sham TMS and assessment in one visit, followed by TMS and assessment the next visit.

What is being measured

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

  1. The effect of symptom provocation on TMS-mediated changes in the blood-oxygen-level-dependent(BOLD) signal

    BOLD signals measure neural activity indirectly via neurovascular coupling

    Changes in BOLD signals from baseline after TMS +/- symptom provocation will be compared after completion of the crossover study (day 33).

    Measured: 33 Days

  2. The effect of symptom provocation on TMS-mediated changes in the functional connectivity (FC) within and between pathophysiologically-relevant networks.

    FC measures correlation in activity between different brain regions.

    Changes in FC from baseline after TMS +/- symptom provocation will be compared after completion of the crossover study (day 33).

    Measured: 33 Days

  3. The effect of symptom provocation on TMS-mediated changes in the behavioral inhibition system (BIS)/behavioral activation system (BAS) scale score

    BIS/BAS scale is a self reported 24 item questionnaire that assesses the BIS, a motivation system for avoiding aversive outcomes, and BAS, a motivation system for approaching goal-oriented outcomes. The total score for BIS scale ranges from 0 to 28 (7 items ranging from 0-4). The total score for BAS ranges from 0 to 52 (13 items ranging from 0-4). Four questions are fillers. Higher score represents greater severity of symptoms.

    Changes in BIS/BAS scale from baseline after TMS+/- symptom provocation will be compared after completion of the crossover study (day 33).

    Measured: 33 Days

  4. The effect of symptom provocation on TMS-mediated changes in the Eating Disorder Examination - Questionnaire (EDE-Q)

    The EDE-Q is a self report questionnaire of ED symptomatology over the preceding 28 days, that encompasses behavioral and attitudinal symptoms across four domains - dietary restraint, eating concern, shape concern, and weight concern. The subscores are calculated as follows:

    Restraint = (Item 1 + Item 2 + Item 3 + Item 4 + Item 5) / 5; Eating Concern = (Item 6 + Item 7 + Item 9 + Item 15 + Item 34) / 5; Weight Concern = (Item 11 + Item 14 + Item 29 + Item 31 + Item 32) / 5; Shape Concern = (Item 10 + Item 11 + Item 12 + Item 13 + Item 30 + Item 33 + Item 35 + Item 36) / 8; Global Score = (Restraint + Eating Concern + Weight Concern + Shape Concern) / 4 Higher score represents greater severity of symptoms.

    Changes in the EDE-Q score from baseline after TMS +/- symptom provocation will be compared after completion of the crossover study (day 33).

    Measured: 33 days

  5. The effect of symptom provocation on TMS-mediated changes in the Eating Disorder (ED 15) questionnaire.

    The ED 15 questionnaire is a measure of eating disorder symptomatology, designed to measure dynamic, session-by-session fluctuations in ED symptom severity. The overall score ranges from 0-6, as it is calculated as the mean of the scores on all ten items, each ranging from 0-6 on symptom severity. Higher score represents greater severity of symptoms.

    Changes in the ED 15 questionnaire score from baseline after TMS +/- symptom provocation will be compared after completion of the crossover study (day 33).

    Measured: 33 days

Questions about this trial

What is this clinical trial studying?

A study of Binge-Eating Disorder, run by University of Southern California.

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 9 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 13 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

Contact Darrin J Lee, MD PhD (9495220866, darrin.lee@med.usc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The effect of symptom provocation on TMS-mediated changes in the blood-oxygen-level-dependent(BOLD) signal (time frame: 33 Days). The study lists 5 primary outcomes in all. 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 13 Dec 2023.
