Clinical Trial Summary

This study is a multicenter, randomized, double-blind, and sham-controlled trial using the identical protocol as the SNT to replicate the antidepressant efficacy of SNT for TRD. Patients will be recruited and randomly assigned (1:1 ratio) to receive active or sham groups from 5 hospitals in China. The interventions will last for 5 days and both groups will be followed up for 8 weeks on the same time schedules. During the intervention and at least the first 4 weeks of post-treatment, participants will keep a stable antidepressant regimen. The individualized SNT target in the left dorsolateral prefrontal cortex (DLPFC) will be generated from 30 minutes of resting-state functional MRI collected at baseline.

Description:

Repetitive Transcranial Magnetic Training (rTMS) is a non-invasive neuromodulation that has been approved by the Food and Drug Administration (FDA) for treating patients with treatment-resistant depression(TRD). In 2022, the US FDA approved a high-dose intervention called Stanford Neuromodulation Therapy (SNT) to achieve rapid relief of patient symptoms in TRD. This therapy involves 10 1800 pulse Intermittent Theta Burst Stimulation (iTBS) interventions per day for consecutive 5 days on the dorsolateral prefrontal cortex (DLPFC), with 50 minutes inter-session intervals. At the end of the SNT intervention, the response rate reached 71.4% (13.3% in the sham group); At the 4th week follow-up after treatment, the response rate was 69.2% (7.1% in the sham group). This therapy has the advantage of quickly taking effect in the treatment of patients with TRD in a short period. However, there are also some limitations with this therapy, such as the need to undergo 10 high-dose interventions with 1800 pulses per day, which takes about 9 hours and may reduce patient compliance with the treatment. In addition, this study is a single-center small sample trial (14 cases with active and 15 cases with sham stimulation). The SNT therapy brings confidence to TRD patients, its efficacy and safety need to be verified in multicenter, randomized, double-blind, placebo-parallel controlled clinical trials.

Intervention

Device:
• Active iTBS-DLPFC
Participants will receive 10 sessions per day of 1800 pulses per session, lasting for 5 days.
• Sham iTBS-DLPFC
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)	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.	Pretreatment (baseline), 28 days post-treatment
Secondary	Change in MADRS	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), 7 days Post-treatment, 14 days Post-treatment, 21 days Post-treatment, 56 days Post-treatment]
Secondary	Change in the Hamilton Rating Scale for Depression (HAMD-17)	A provider administered questionnaire used to assess remission and recovery from depression. The HAMD-17 is a 17-item questionnaire to assess depression severity. Each item is scored from 0-4, with higher scores representing increasing depression severity.

Secondary	Change in the Hamilton Rating Scale for Depression (HAMD-6) Score	The Hamilton Depression Rating Scale (HDRS, also known as Ham-D) is the most widely used clinician-administered depression assessment scale.; The Ham-6 version consists of 6 items assessing for: 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 symptoms item, which is scored 0 to 2. On the HAM-6 there can be a total score of 22. Higher scores represent higher depression severity. Here, we report a count of participants with an overall increase, decrease or no change in total HAM-6 score.; Participants with an increase in total score (row 3) would signify a worse outcome than participants with a decrease in total score.
