pBFS-guided High-dose TMS Over DMPFC for Treatment-resistant Major Depressive Disorder

Personalized Brain Functional Sectors (pBFS)-Guided DMPFC With High-dose rTMS for Treatment-resistant Depressive Disorder: a Randomized, Double-blind, Sham-controlled Trial

The investigators aim to evaluate the safety and efficacy of pBFS-guided DMPFC target and high-dose rTMS therapy for the treatment of patients with treatment-resistant depression

Study Overview

• Status: Recruiting
• Conditions: Depression; Major Depressive Disorder; Severe Depression
• Intervention / Treatment: Device: active TMS; Device: sham TMS

Detailed Description

Repetitive transcranial magnetic stimulation (rTMS) is an established therapy for treatment-resistant depression. Currently, the FDA cleared the SAINT Neuromodulation System for the treatment of Treatment-Resistant Depression(TRD) over the left dorsolateral prefrontal cortex (DLPFC). This methodology has been effective in a short period of time for treatment-resistant depression. However, some patients may not be able to persist in completing the treatment because they cannot bear the pain during treatment. The dorsomedial prefrontal cortex (DMPFC) region is relatively posterior, and DMPFC as an intervention target has been proven to have antidepressant effects, and patients have better pain tolerance during treatment, which can be used as an alternative to DLPFC target, so it is urgent to explore the effectiveness and safety of high-dose iTBS targeting DMPFC in the treatment of depression.

After being informed about the study and potential risks. All patients giving written informed consent will undergo a screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requirements will be randomized in a blind manner in a 2:1 ratio to the active-rTMS group, and sham-rTMS group. Then all participants will undergo a 5-day rTMS modulation followed by two-week and four-week follow-up visits. Participants will keep a stable treatment regime during treatment and the four-week follow-up.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: active TMS; active iTBS coupled with medical therapy	Device: active TMS; Participants will receive 10 sessions per day of 1800 pulses per session, lasting for 5 days. Individualized target in the DMPFC will be generated using the pBFS method
Sham Comparator: sham TMS; Sham iTBS coupled with medical therapy	Device: sham TMS; The parameters in the sham arm are the same as in the active stimulation group. Stimulation was delivered by the same device as the active group fitted with a sham coil

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
change in Montgomery-Asberg Depression Rating Scale (MADRS)	The MADRS is a validated instrument stratifying the severity of depressive episodes in adults. The MADRS has an overall score ranging from 0 (no depression) to 60 (worst depression).	Baseline, Day 5

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in MADRS	A provider-administered questionnaire was used to assess remission and recovery from depression. The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. The MADRS has an overall score range from 0-60, with higher scores corresponding to higher levels of depression	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
Change in Hamilton Depression Scale (HAMD-17)	A provider-administered questionnaire was used to assess remission and recovery from depression. The Hamilton Depression Rating Scale (HAMD) is the most widely used clinician-administered depression assessment scale. The Ham-17 version consists of 17 items assessing mood, guilt, general somatic symptoms, work and activities, anxiety, and slowness of thought and speech. Each item is scored on a scale of 0 to 4, except for the somatic, sleep, and insight items which are scored 0 to 2. On the HAMD-17 there can be a total score of 52. Higher scores represent higher depression severity.	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
Change in Quick Inventory of Depressive Symptomatology Self-Report (QIDS_SR)	A provider-administered questionnaire was used to assess remission and recovery from depression. The 16-item QIDS_SR is a widely used self-report instrument covering depressive symptoms incorporating nine Diagnostic and Statistical Manual of Mental Disorder-IV (DSM-IV) diagnostic criteria for major depressive disorders. Each item is scored on a scale of 0 to 4. Higher scores represent higher depression severity.	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
cognitive change in Digit Symbol Substitution Test (DSST)	Cognitive scores are measured using Chinese brief cognitive test (C-BCT), the DSST equires a subject to match symbols to numbers according to a key located on the top of the page	Baseline, Day 5 (Immediate Post-treatment)
cognitive change in continuous performance test (CPT)	CPT from the C-BCT measures a person's sustained and selective attention	Baseline, Day 5 (Immediate Post-treatment)
cognitive change in Trail-Making Test (TMT)	The TMT test from the C-BCT can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning	Baseline, Day 5 (Immediate Post-treatment)
cognitive change in Digit Span Test (DST)	DST from the C-BCT is a measure of verbal short term and working memory that can be used in two formats, Forward Digit Span and Reverse Digit Span	Baseline, Day 5 (Immediate Post-treatment)
Safety estimated using SSI	Scale for Suicide Ideation (SSI) measures suicide ideation	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
Safety estimated using YMRS	Young Mania Rating Scale(YMARS) measures mania	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
