Recruiting studies
- NCT07113652Recruiting
Brain stimulation for obsessive-compulsive disorder
This trial tests a new type of noninvasive brain stimulation called temporal interference stimulation for people with OCD. It may help reduce symptoms when standard medications have not worked well enough.
Shanghai, Shanghai MunicipalityAges 18–50 - NCT07103902Recruiting
Exercise for OCD symptoms study
This study tests whether aerobic exercise can help reduce OCD symptoms. You will be asked to exercise regularly while researchers track changes in your symptoms.
New Haven, ConnecticutAges 18–64 - NCT04539951RecruitingPhase 2
Trial for newly treated obsessive-compulsive disorder
This phase 2 study tests an OCD treatment strategy for people who have not yet had OCD medications or recent OCD therapy. It aims to reduce OCD symptoms, especially for those with moderate-to-severe symptom levels.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT07065669Recruiting
TMS for teens with OCD
This study tests if transcranial magnetic stimulation (a non-invasive brain stimulation technique) can help treat obsessive-compulsive disorder in adolescents aged 13-17. It aims to see if this treatment can reduce OCD symptoms when added to stable medications or therapy.
San Francisco, CaliforniaAges 13–17 - NCT07031544Recruiting
Deep brain stimulation for severe OCD
This study tests whether implanting a small device deep in the brain—like a pacemaker for OCD—can help people whose severe OCD hasn't gotten better with standard medications and therapy.
Guangzhou, GuangdongAges 18–65 - NCT06017713Recruiting
Brain stimulation plus exposure for stubborn OCD
This trial tests whether a gentle brain stimulation (tDCS) combined with facing your fears can help people with hard-to-treat OCD. If you've tried multiple treatments without relief, this study may offer a new option.
PoitiersAges 18–70 - NCT05577598Recruiting
Brain scan study of deep brain stimulation in OCD
This trial uses a special PET scan to see how brain sugar use changes during deep brain stimulation for obsessive-compulsive disorder (OCD). It may help researchers understand what brain activity patterns relate to treatment response.
Vienna, State of ViennaAges 18–75 - NCT06942494Recruiting
CBT Self-Help for Teens with OCD (Family-Based)
This study tests a family-based cognitive behavioral therapy (CBT) self-help program for teens with OCD. It's designed to help you and a parent work together to manage OCD symptoms at home.
Xuhui, Shanghai MunicipalityAges 10–17 - NCT06917339Recruiting
A study looking at past treatment records
This trial looks back at medical records in the TrakStar database to understand how treatments were given. It does not test a new drug, but helps researchers learn from past treatment experiences.
Malvern, PennsylvaniaAges 5–120 - NCT05577585Recruiting
Ketamine treatment for obsessive-compulsive disorder symptoms
This study tests whether ketamine can reduce obsessive-compulsive disorder (OCD) symptoms and how it affects stress and thinking. It also compares ketamine to usual care to see if benefits and side effects differ.
Vienna, State of ViennaAges 18 years+ - NCT06882902Enrolling by invitation
Brain wave study for OCD habits
This study uses an EEG (a safe, painless cap that records brain activity) to look for unique brain patterns linked to habit behaviors in people with OCD. Participating could help researchers better understand OCD habits and improve future treatments.
Shanghai, Shanghai MunicipalityAges 18–50 - NCT06834217Recruiting
Brain stimulation and facing fears in OCD
This study is testing a gentle, non-invasive brain stimulation method called tDCS to see if it can help people with OCD reduce their symptoms by practicing facing their fears (a process called extinction). The trial involves wearing a head cap that delivers a mild electrical current while doing computer exercises.
New Haven, ConnecticutAges 18–70 - NCT06816511Enrolling by invitation
Focused ultrasound study for hard-to-treat OCD
This trial tests if a non-invasive ultrasound treatment can help people with obsessive-compulsive disorder (OCD) that hasn't improved with standard therapies. You must have had OCD for at least five years, have severe symptoms, and have tried multiple medications and cognitive-behavioral therapy without enough benefit.
TaipeiAges 18–65 - NCT06804525Recruiting
Adapting a mental health survey in Hong Kong
This study adapts a mental health survey for Hong Kong adults. It is open to adults aged 25 and older who live in randomly selected households and can speak Chinese or English.
Hong KongAges 25 years+ - NCT06763081Recruiting
SSRI side effects genetics study
This study looks at why some people have behavioral side effects when taking SSRI antidepressants like Prozac or Zoloft. It hopes to find a genetic reason to help doctors choose safer treatments in the future.
Winnipeg, ManitobaAges 6–24 - NCT06754319Recruiting
Gut bacteria and brain connection in child OCD
This study looks at how the bacteria in your gut might affect OCD in children and teens. It tests a possible link between your gut, brain, and OCD symptoms.
Shanghai, Shanghai MunicipalityAges 7–17 - NCT06717165Recruiting
Brain stimulation with talk therapy for OCD
This study tests if adding a gentle brain stimulation technique (tACS) to cognitive behavioral therapy (CBT) can help reduce OCD symptoms more than CBT alone. It is for adults with OCD who have not completed a full course of CBT before.
Shanghai, Shanghai MunicipalityAges 18–60 - NCT06720090RecruitingEarly Phase 1
Light therapy for obsessive-compulsive disorder (OCD)
This study tests whether morning light therapy can help people with OCD who have late bedtimes. It aims to improve symptoms by shifting your body's internal clock earlier.
St Louis, MissouriAges 17–35 - NCT06724029Recruiting
Neurosurgery outcomes research for multiple conditions
This study collects data from people having brain or spine surgery for many different conditions. It aims to understand how well different treatments work and how people recover. If you are scheduled for certain brain, spine, or nerve surgeries, you may be able to join.
Bergamo, BGAges 18 years+ - NCT06692114Recruiting
Deep brain stimulation for obsessive-compulsive disorder
This trial tests whether deep transcranial magnetic stimulation (a non-invasive brain stimulation technique) can help treat obsessive-compulsive disorder (OCD) in people who haven't improved enough with standard treatments like medication or therapy.
Shanghai, Shanghai MunicipalityAges 18–50 - NCT06660225Recruiting
Deep brain stimulation for severe OCD
This trial tests if deep brain stimulation (a surgical treatment that uses electrical pulses to adjust brain activity) can help people with severe obsessive-compulsive disorder (OCD) that has not improved with other treatments. It is for adults aged 22 to 75 who have had OCD symptoms for over 5 years.
Dallas, TexasAges 22–75 - NCT06647589Recruiting
Acceptance and commitment therapy for religious ocd

Birmingham, AlabamaAges 18 years+ - NCT06585618Recruiting
Pediatric Deep Brain Stimulation Registry
This study creates a list of children who already have or plan to get Deep Brain Stimulation (DBS) to see how it helps with movement problems. Joining helps doctors learn more about how DBS works in kids.
Boston, MassachusettsAges birth–18 years - NCT03826693RecruitingPhase 2
Nitrous oxide trial for obsessive-compulsive disorder symptoms
This Phase 2 pilot study tests whether breathing nitrous oxide (laughing gas) can reduce symptoms of obsessive-compulsive disorder (OCD). It compares what happens during a treatment-free period and then during the study treatment to see if symptoms improve.

Common questions
- Are there clinical trials for obsessive-compulsive disorder?
- Yes. Clin2 currently lists 104 recruiting obsessive-compulsive disorder studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a obsessive-compulsive disorder trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a obsessive-compulsive disorder trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
