In this triple-blind randomized controlled trial, we ask if targeting intermittent theta burst stimulation (iTBS) based on individual resting state connectivity improves treatment outcomes in major depressive disorder (MDD). For the trial, we will recruit 210 patients with major depressive disorder. Each patient will undergo a 30-40-minute MRI scan, after which they will receive a 6-week standard iTBS treatment. Participants will be randomized to receive iTBS either to the standard neuronavigated target (a technique for treatment location targeting, based on group-average connectivity) or to a personalized connectivity-guided target selected based on individual functional connectivity scans. The main outcome of this trial is response rate as determined by ≥ 50% reduction in Grid HRSD-17 scores. Secondary outcomes include remission rate, change in depression, anxiety and anhedonia symptoms, quality of life, and biological measures of heart rate variability, objective sleep measures and daily activity as a proxy of anhedonia - defined as a reduced ability to experience pleasure.

Exclusion criteria: Participants fulfilling any of the following criteria will be excluded from the study: 1. diagnosis of bipolar I or II disorder, based on the DSM-5 criteria 2. current or past (< 3 months) substance (excluding caffeine or nicotine) or alcohol use disorder, as defined in DSM-5 criteria. Based on the DSM-5 criteria, mild cannabis or alcohol use disorder would be permissible in the past 3 months, moderate to severe would be an exclusion. 3. current use of illegal substances or cannabis (unless medical use, see note below), confirmed by urine drug screen 4. have a concomitant major unstable medical or neurologic illness (e.g. uncontrolled diabetes or renal dysfunction), 5. organic cause to the depressive symptoms (e.g. thyroid dysfunctions), as ruled out by the referring physician 6. acute suicidality or threat to life from self-neglect, 7. are pregnant or breastfeeding, or thinking of becoming pregnant during course of treatment (pregnancy will be assessed by a urine test), 8. have a specific contraindication for TMS (e.g., personal history of epilepsy or seizure, metallic head implant, pacemaker), 9. unwilling to maintain current antidepressant regimen, 10. are taking more than 1 mg of lorazepam per day or equivalent, 11. any other condition that, in the opinion of the investigators, would adversely affect the participant's ability to complete the study, 12. any contraindications for MRI 13. have failed a course of ECT within the current depressive episode due to the lower likelihood of response to rTMS (if they have had failed ECT in the past, this does not exclude them) |
