OBJECTIVE: Scalp-based repetitive transcranial magnetic stimulation targeting the left dorsolateral prefrontal cortex (DLPFC) does not account for interindividual variability. This trial was designed to determine whether individualized connectivity-guided intermittent theta-burst stimulation (iTBS) improves antidepressant outcomes compared with 5-cm targeting. METHODS: In this single-center, randomized, double-blind, three-arm trial (February 2023-March 2025), adults ages 18-65 years with major depressive disorder or bipolar II depression (≥1 antidepressant failure) were randomly assigned to receive 20 sessions of iTBS over 2 weeks using robotic neuronavigation with one of three targeting strategies: 5-cm rule, functional connectivity (FC)-guided targeting showing negative resting-state connectivity with the subgenual anterior cingulate cortex (sgACC), or structural connectivity (SC)-guided sites defined by probabilistic tractography to the sgACC. The primary outcome was percentage reduction in 17-item Hamilton Depression Rating Scale (HAM-D) score at week 2. Secondary outcomes included HAM-D score reduction at weeks 6 and 12, response or remission, self-reported symptoms, performance on a cognitive battery, and adverse events. RESULTS: Of 123 randomized participants, 119 were included in the modified intention-to-treat analyses (5-cm, N=40; SC-guided, N=39; FC-guided, N=40). SC-guided iTBS produced significantly greater HAM-D score reduction than the 5-cm rule at week 2 (l...
