First seen Jan 05, 2026 · Last updated May 16, 2026 · Updated 20 times
Summary
This study tests whether tolcapone, a drug currently used for Parkinson's disease, can safely reduce symptoms in adults with moderate to severe obsessive-compulsive disorder (OCD). About 49 participants will receive either tolcapone or a placebo to see if it improves OCD severity, thinking skills, and quality of life. The goal is to find a new treatment option for people whose OCD is not well controlled.
