Accelerated Versus Standard Intermittent Theta Burst Stimulation for Major Depressive Disorder

Kurzzusammenfassung

This randomized, rater-blinded clinical trial aims to compare the effectiveness, safety, and tolerability of accelerated intermittent theta burst stimulation (iTBS) with standard iTBS in adults with major depressive disorder (MDD). Participants will be randomly assigned in a 1:1 ratio to receive either accelerated or standard iTBS targeting the left dorsolateral prefrontal cortex. Participants may be psychotropic-medication naïve or may continue stable psychotropic medication according to the protocol-defined medication stability criteria. The accelerated iTBS group will receive 45 treatment sessions over approximately 15 treatment days, while the standard iTBS group will receive 20 treatment sessions over 4 weeks. The primary objective is to compare changes in depressive symptom severity, measured using the 17-item Hamilton Depression Rating Scale (HAM-D17), from baseline to the end-of-treatment assessment. Secondary and exploratory assessments include treatment response and remission, sleep quality, quality of life, cognitive measures, safety and tolerability, resting electroencephalography (EEG), and transcranial magnetic stimulation combined with EEG (TMS-EEG).
