Clinical Trial Summary

We aim to evaluate the safety and efficacy of pBFS-guided high-dose rTMS therapy with short inter-session interval for patients with treatment-resistant depression

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 (L-DLPFC). This methodology has been effective in a short period of time for treatment-resistant depression. The limitation of this approach includes the long inter-session interval (~50min) of the treatment, patients need to wait about 8 hours for 10 session's intervention per day. Therefore, it is urgent to explore the efficacy and safety of rTMS with a short inter-session interval (e.g. 20 min) that is more acceptable for TRD patients. 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 double-blind manner in a 1:1:1 ratio to the active short-interval rTMS group, active short-interval rTMS group, and active long-interval rTMS group. Then all participants will undergo a 5 day rTMS modulation followed by a four-week follow-up visit.

Intervention

Device:
• Active rTMS with short inter-session interval
Participants in this group will receive ten sessions per day of 1800 pulses per session, at an inter-session interval of 20 min for 5 days. The individualized target will be generated using the personalized Brain Functional Sectors (pBFS) method.
• Sham rTMS with short inter-session interval
Participants in this group will receive ten sessions per day of 1800 pulses per session, at an inter-session interval of 20 min for 5 days, using sham stimulation coils that comprehensively mimic the active condition. The individualized target will be generated using the personalized Brain Functional Sectors (pBFS) method.
• Active rTMS with long inter-session interval
Participants in this group will receive ten sessions per day of 1800 pulses per session, at an inter-session interval of 50 min for 5 days. The individualized target will be generated using the personalized Brain Functional Sectors (pBFS) method.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Montgomery-Asberg Depression Rating Scale (MADRS) scores from baseline to immediate post-treatment	The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Higher scores represent higher depression severity. The MADRS has an overall score ranging from 0 (no depression) to 60 (worst depression).	Baseline, Day 5 (Immediate Post-treatment)
Secondary	Change in MADRS, HAMD-17, and QIDS_SR from baseline to different time points post-treatment	The Hamilton Depression Rating Scale (HAMD) is the most widely used clinician-administered depression assessment scale. The HAMD-17 version consists of 17 items. Higher scores represent higher depression severity. 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. Higher scores represent higher depression severity.	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
Secondary	Remission and response rates estimated using MADRS, HAMD, QIDS_SR	Three questionnaires were used to assess the response rate and remission rate of depression separately. Response is defined as an symptom improvement =50% on these scales; remission was defined as a score< 11 on MADRS, or <8 on HAMD, or <6 on QIDS_SR.	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
Secondary	Safety measures using SSI and YMRS	Scale for Suicide Ideation (SSI) and Young Mania Rating Scale (YMRS) were used to estimated suicide ideation and manic symptoms	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment
