Clinical Trial Summary

The aim of this study is to explore the effectiveness and safety of different doses of neural regulation under the guidance of pBFS technology in improving symptoms in patients with moderate to severe depressive disorders.

Description:

In 2022, the FDA cleared a large dosage of repetitive transcranial magnetic stimulation for treatment-resistant depression (TRD), which requires 10 sessions per day of 1,800 pulses per session for a total of 18,000 pulses per day. The inter-session interval is 50 min, and it costs patients 9 hours for the intervention. The investigators assume that patients with moderate to severe depression may not need 10 sessions per day, patients may achieve response or remission with a less amount of dosage, which will save the cost of treatment. Hence, the investigators try to find the optimal treatment dosage for patients with moderate to severe 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 double-blind manner in a 1:1:1:1:1 ratio to each active rTMS group with different pulses (4×1800 pulses, 6×1800 pulses, 8×1800 pulses, 10×1800 pulses) and sham-control group. And then all participants will undergo a 5-day rTMS treatment followed by four- and eight weeks follow-up visits. Participants will keep a stable treatment regime during treatment and the four-week follow-up.

Intervention

Device:
• 4 session rTMS
Participants will receive 4 sessions per day of 1800 pulses per session, lasting for 5 days. Individualized targets will be generated using the pBFS method.
• 6 session rTMS
Participants will receive 6 sessions per day of 1800 pulses per session, lasting for 5 days. Individualized targets will be generated using the pBFS method.
• 8 session rTMS
Participants will receive 8 sessions per day of 1800 pulses per session, lasting for 5 days. Individualized targets will be generated using the pBFS method.
• 10 session rTMS
Participants will receive 10 sessions per day of 1800 pulses per session, lasting for 5 days. Individualized targets will be generated using the pBFS method.
• sham rTMS
The parameters in the sham arms are the same as the active stimulation groups. Stimulation was delivered by the same device as the active group fitted with a sham coil.

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 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(Immediate Post-treatment)
Secondary	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, 56 days Post-treatment
Secondary	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-17) is the most widely used clinician-administered depression assessment scale. The HAMD-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 HAM-17 there can be a total score of 22. Higher scores represent higher depression severity.	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment, 56 days Post-treatment
Secondary	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, 56 days Post-treatment
Secondary	Safety estimated using SSI, YMRS	Scale for Suicide Ideation (SSI) measures suicide ideation, Young Mania Rating Scale(YMARS) measures mania	Baseline, Day 5 (Immediate Post-treatment), 14 days Post-treatment, 28 days Post-treatment, 56 days Post-treatment
Secondary	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
Secondary	cognitive change in continuous performance test (CPT)	CPT from the C-BCT measures a person's sustained and selective attention	Baseline, Day 5
Secondary	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
Secondary	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
