NCT04037592

Brief Summary

This study evaluates an association between different dosage and the antidepressant efficacy of theta burst stimulation in patients with treatment-resistant depression. In a double-blind design, All patients are randomized to three groups, i.e. standardized dosage intermittent theta-burst stimulation treatment, high dosage intermittent theta-burst stimulation treatment or sham treatment.

Outcome Measures

Primary Outcomes (1)

  • Percentage change in 17-item Hamilton Depression Rating Scale

    the altered percentage of 17-item Hamilton Depression Rating Scale (range, 0 to 52, with higher scores indicating more depression)

    Baseline, Week 1, Week 2, Week 3, Week 15(three-month after brain stimulation), Week 27(Six-month after brain stimulation)

Secondary Outcomes (15)

  • Response rate after 3-week treatment at the end of iTBS sessions and three and six month after.

    Baseline, Week 1, Week 2, Week 3, Week 15(three-month after brain stimulation), Week 27(Six-month after brain stimulation)

  • Remission rate after 3-week treatment

    Baseline, Week 1, Week 2, Week 3, Week 15(three-month after brain stimulation), Week 27(Six-month after brain stimulation)

  • Changes in Clinical Global Index

    Baseline, Week 1, Week 2, Week 3

  • Changes in depression severity, rated by self-reported

    Baseline, Week 1, Week 2, Week 3

  • Changes in Young Mania Rating Scale

    Baseline, Week 1, Week 2, Week 3

  • +10 more secondary outcomes

Study Arms (3)

Active standardized iTBS-DMPFC

EXPERIMENTAL

This active group will receive standardized dosage of intermittent theta-burst on dorsomedial prefrontal cortex(DMPFC)

Device: Active standardized iTBS-DMPFC

Active high-dosage iTBS-DMPFC

EXPERIMENTAL

This active group will receive high dosage of intermittent theta-burst on dorsomedial prefrontal cortex(DMPFC)

Device: Active high-dosage iTBS-DMPFC

Sham standardized iTBS-DMPFC or high-dosage iTBS-DMPFC

SHAM COMPARATOR

Patients in the sham group will receive the same standardized or high-dosage iTBS performing by a sham coil

Device: Sham standardized iTBS-DMPFC or high-dosage iTBS-DMPFC

Interventions

Participants in the standardized dosage(600 pulse) of intermittent TBS(iTBS) active stimulation group will receive 3-week three-pulse 50-Hz bursts administered every 200 milliseconds (at 5 Hz) at an intensity of 80% active motor threshold (MT) to bilateral DMPF, twice a day. Bilateral side DMPFC will be targeted by MRI-neuronavigation system. Stimulation will be delivered to the DMPFC using a Magstim stimulator.

Active standardized iTBS-DMPFC

Participants in the standardized dosage(1800pulse) of intermittent TBS(iTBS) active stimulation group will receive 3-week three-pulse 50-Hz bursts administered every 200 milliseconds (at 5 Hz) at an intensity of 80% active motor threshold (MT) to bilateral DMPF, twice a day. Bilateral side DMPFC will be targeted by MRI-neuronavigation system. Stimulation will be delivered to the DMPFC using a Magstim stimulator.

Active high-dosage iTBS-DMPFC

Half of the patients in the sham group received 3-week the same standardized iTBS parameter stimulation (standardized sham-iTBS), and the other half received the same high dosage iTBS parameter stimulation using a sham coil (high dosage sham-rTMS), which also improved the blinding process

Sham standardized iTBS-DMPFC or high-dosage iTBS-DMPFC

Eligibility Criteria

Age21 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female, 21 to 70 years of age.
  • Diagnosed with the recurrent Major depressive disorder (MDD) and currently having a Major Depressive Episode (MDE)
  • Participants failed to respond to at least one adequate antidepressant treatment in their current episode
  • Participants have a Clinical Global Impression - Severity score of at least 4 and a total score of at least 18 on the Hamilton Depression Rating Scale (HDRS-17) at both screening and baseline visits ( Day -14 and Day 0)
  • Participants must discontinue their antidepressant medications at least for one week ( at least two weeks if Fluoxetine) prior to the TMS intervention and keep antidepressant-free during the study duration.
  • Participants also failed to respond to one complete left-sided DLPFC 10Hz rTMS/piTBS treatment course.

You may not qualify if:

  • a lifetime psychiatric history of bipolar disorder, schizophrenia, psychotic disorders, or organic mental disorder including substance abuse and dependence (based on DSM-IV criteria)
  • Participants with a lifetime medical history of major systemic illness and clinically significantly abnormal screening examination that might affect safety, study participation, or confound interpretation of study results.
  • Participants with a lifetime medical history of neurological disorder records (e.g., stroke, seizure, traumatic brain injury, post brain surgery), brain implants (neurostimulators), cardiac pacemakers
  • Women with breastfeeding or pregnancy
  • Participants with a current strong suicidal risk (i.e., a score of 4 on item 3 of the HDRS-17)
