Transcranial magnetic stimulation combined with therapy for OCD

Precision Medicine for OCD - Biobehavioral Tracking of Transcranial Magnetic Stimulation (TMS) With Exposure and Response Prevention (ERP) for Refractory OCD

NA · University of Southern California · NCT07146438

This trial will test whether combining repetitive transcranial magnetic stimulation (rTMS) with either Exposure and Response Prevention (ERP) or supportive therapy helps adults with OCD.

What this trial studies

This randomized, controlled pilot enrolls adults with OCD to receive daily rTMS targeted to the dorsomedial prefrontal cortex/anterior cingulate cortex five days per week for six weeks while also receiving either virtual ERP or supportive therapy twice weekly. Participants wear a Fitbit and complete daily smartphone check-ins to collect behavior and physiology data, and undergo baseline and repeat resting-state fMRI to study neural predictors and mechanisms of response. The protocol uses an FDA-cleared rTMS treatment approach and collects symptom, functioning, and quality-of-life measures across a 16-week study period. The design tests feasibility, tolerability, preliminary clinical effects, and whether wearable and imaging markers can help predict who benefits.

Who should consider this trial

Good fit: Adults with DSM-5 OCD who live in Southern California, have completed at least ten ERP sessions previously, have tried SRI medication, can attend in-person rTMS five days per week for six weeks, and can keep psychotropic medications stable are the ideal candidates.

Not a fit: People with a primary psychiatric diagnosis other than OCD, active substance use disorder, active suicidality or psychosis, a history of seizures, severe neurological impairment, pregnancy, or prior rTMS are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, the combination could produce larger or faster reductions in OCD symptoms and help personalize treatment using wearable and brain-imaging markers.

How similar studies have performed: Prior trials (and FDA clearance for certain TMS approaches) support rTMS as beneficial for some people with OCD, but combining rTMS with ERP and using wearables plus rsfMRI for prediction is relatively novel and less tested.
