Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the differences in efficacy between transcranial magnetic stimulation (TMS) and intermittent theta burst stimulation (iTBS) treatment in subjects suffering from major depressive disorder.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Up to 30 patients of any gender aged from 18 to 70 years old will be recruited for inclusion once candidacy has been established by screening criteria.

Once recruited, patients will be randomly assigned to the TMS treatment group or the iTBS treatment group. Patients will be blinded to their group assignment, but will be informed of their assignment upon the final outcome measure collection timepoint (e.g., 1 month post-treatment). Patients who failed to respond by 1-month post iTBS or TMS treatment will be allowed to cross-over into the other treatment group and will be re-enrolled into the study.

For patients assigned to the TMS treatment group, the treatment protocol will consist of 20 sessions of TMS treatment. Each TMS session will deliver 5,000 pulses (120-140% MT, continuous temperature of 24C) over an 61 minute, 51 second time period. Patients will have one TMS session per day, five days a week, until their treatment is completed (approximately four weeks). Upon completion, the patient's depressive symptomatology and severity will be assessed using the same outcome measures used at baseline.

For patients assigned to the iTBS treatment group, the treatment protocol will consist of 20 sessions of iTBS treatment. Each iTBS session will deliver 1,800 pulses (120-140% MT, continuous temperature of 24C) over an 9-minute-40-second period. Patients will have up to four iTBS sessions per day, five days a week, until their treatment is completed (approximately 1 week). Upon completion, the patient's depressive symptomatology and severity will be assessed using the same outcome measures used at baseline.

Study Design

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

This is a single-site, randomized, blinded, clinical trial comparing the efficacy of transcranial magnetic stimulation (TMS) and intermittent theta burst stimulation (iTBS) in subjects with treatment refractory depression (trMDD). The study will recruit 30 subjects, all suffering from treatment refractory depression (trMDD). Half of the subjects (15) will be randomized to the TMS treatment group, while the other half will be assigned to the iTBS treatment group. The randomization ratio will be 1:1.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transcranial Magnetic Stimulation

All patients are required to have an advanced MRI of the brain including a structural T1, volume measurements of various brain regions, ASL, and BOLD sequences. Patients will also undergo an in-scanner task designed to activate key neurofunctional regions of interest.

Group Type EXPERIMENTAL

Transcranial Magnetic Stimulation

Intervention Type DEVICE

5,000 pulses (120-140% MT, continuous temperature of 24C) will be delivered per session (see Appendix A for timing parameters). Patients will have one TMS session per day, five days a week, until their treatment is completed (approximately four weeks).

Theta Burst Stimulation

All patients are required to have an advanced MRI of the brain including a structural T1, volume measurements of various brain regions, ASL, and BOLD sequences. Patients will also undergo an in-scanner task designed to activate key neurofunctional regions of interest.

Group Type EXPERIMENTAL

Theta Burst Stimulation

Intervention Type DEVICE

One session of iTBS will deliver 1,800 pulses (120-140% MT, continuous temperature of 22ºC) over an 9-minute-40-second period. The minimum break period between iTBS sessions is 25 minutes.
