Accelerated TMS for Depression and OCD

Study Overview
=================
Brief Summary
-----------------
Repetitive transcranial magnetic stimulation (rTMS) is a FDA-approved treatment for depression and Obsessive Compulsive Disorder (OCD). The goal of the study is to learn how to optimize the treatment to improve symptoms of depression and OCD. This research project will test a new accelerated 5-day accelerated rTMS protocol for treating symptoms of depression and OCD. A second goal of this study is to identify biomarkers of depression and OCD in the brain using functional magnetic resonance imaging (fMRI). This approach will predict who will benefit from TMS, determine the optimal treatment target, and improve treatment outcomes. Subjects will receive a clinical assessment of symptoms and an fMRI brain scan before and after each treatment course to measure the effect of treatment on symptom severity and on fMRI measures of functional connectivity. Participants will be randomized to receive rTMS targeting either the lateral prefrontal cortex (LPFC) or the dorsomedial prefrontal cortex (DMPFC). Participants will complete a 5-day course of rTMS delivered hourly for 10 hours per day. Participants who show a partial response to treatment but not a full response will then receive a second 5-day course. Treatment non-responders will be crossed over to receive rTMS targeting the opposite brain area. The primary hypothesis is that accelerated rTMS treatment will yield rapid improvement in symptoms for patients with depression and OCD in just 5 days, and that response rates can be further improved by adding a second 5-day treatment course.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: Subjects will be randomized to receive rTMS targeting the DMPFC or the LPFC. The treatment course will be 10 sessions per day hourly for 5 days. Participants may have the option to be crossed over to receive rTMS targeting the opposite brain area, enabling us to test whether participants who do not respond well to one target might respond to stimulation of another target. The option to offer a second course of treatment will be based on clinical judgement and re-evaluation of the participant.
Masking: None (Open Label)
