Ketamine study for OCD after prior treatment failed
This Phase 2 study tests how ketamine may work quickly in people with obsessive-compulsive disorder (OCD), especially after at least one standard treatment didn’t help.

What taking part in a opioid use disorder study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
