Intermittent Theta Burst Stimulation for Maintenance Therapy in Depression

Summary

This is a randomized, multi-center, open-label study in which patients with depression who responded to an open-label treatment with intermittent theta burst stimulation (iTBS) will receive this procedure as maintenance therapy. The patients will be randomized to two study arms. The arms differ in the frequency of stimulation (standard iTBS (5 treatments every working day for one week) vs. accelerated iTBS (5 treatments in one day)). For purposes of effect size estimation an interim analysis will be done after half of the patients.
