China Refractory Obsessive-Compulsive Disorder Deep Brain Stimulation Study

Phase 2
Withdrawn
Conditions
Obsessive Compulsive Disorder
Interventions
Device: Sham Bilateral Nucleus Accumbens DBS
Device: Bilateral Nucleus Accumbens DBS (Suzhou Sceneray)
Registration Number
NCT02398318
Lead Sponsor
Ruijin Hospital
Brief Summary

Refractory obsessive-compulsive disorder (OCD) is a disabling condition. Deep brain stimulation (DBS) of the nucleus accumbens is the most tested therapeutic avenue for refractory OCD. However, large scale randomized controlled trials to evaluate the effectiveness of this approach are rare.
