A Double-Blinded, Randomized, Crossover Trial of Stereoencephalography- Guided Multi-Lead Deep Brain Stimulation for Treatment-Refractory Obsessive- Compulsive Disorder (SEEG-Guided DBS for OCD)
Katherine Scangos
Summary
This is a multi-site, double-blinded, randomized, crossover study design for SEEG-guided 4-lead DBS for treatment-refractory OCD, followed by open label stimulation for an additional 6 months. The study will be conducted in 3 stages: Stage 1 will consist of SEEG brain mapping and optimization of stimulation parameters. Stage 2 will consist of DBS surgery and further optimization of stimulation parameters. Stage 3 will be randomized, crossover treatment, followed by open label treatment.

Inclusion Criteria: 1. ≥ 22 years and ≤ 75 years of age, at the time of screening 2. Chronic (\> five years preceding the date of enrollment) OCD, diagnosed as per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition guidelines (DSM-5) 1. Presence of obsessions, compulsions, or both 2.

Interventions
- DevicePMT Stereoencephalography (SEEG)
For Stage 1 of this study, we will be implanting depth electrodes to record stereoencephalography across a network of brain regions.
- DeviceVercise Genus™ Deep Brain Stimulation (DBS) System or Percept™ PC Neurostimulation System
For Stages 2 and 3 of this study, we intend to use the DBS system to treat patients with severe symptoms of chronic, treatment-refractory OCD by targeting stimulation to sites that have been determined to have therapeutic benefit during our SEEG Invasive Monitoring phase.
