Condition: Depression · Depressive Disorder, Major · Depressive Episode · Sponsor: The Royal Ottawa Mental Health Centre
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.
