What this trial studies

This study involves a randomized, multi-center, open-label approach where patients with depression who previously responded to intermittent theta burst stimulation (iTBS) will receive this treatment as maintenance therapy. Participants will be divided into two groups based on the frequency of stimulation: one group will receive standard iTBS over a week, while the other will receive accelerated iTBS in one day. An interim analysis will be conducted after half of the patients have been treated to estimate the effect size.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with a diagnosis of a depressive episode, recurrent depressive disorder, or bipolar disorder who have responded positively to prior iTBS treatment.

Not a fit: Patients with severe neurological diseases or those with contraindications for TMS, such as electrical implants, will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel maintenance therapy option for patients with depression, potentially improving their long-term outcomes.

How similar studies have performed: While the use of iTBS has shown promise in treating depression, this specific approach as maintenance therapy is relatively novel and has not been extensively tested in prior studies.
