Quality-of-life study for treatment-resistant OCD with DBS
This study looks at whether deep brain stimulation (DBS) helps people with long-term, treatment-resistant obsessive-compulsive disorder (OCD), and how it affects quality of life. It involves careful screening because it’s meant for OCD that has not responded to several medication and therapy attempts.
CréteilAges 18–69 - NCT05048251Recruiting
Targeted brain stimulation for OCD with contamination symptoms
This study tests a personalized brain-stimulation approach to help people with obsessive-compulsive disorder (OCD) focused on contamination worries. If you have the “contamination” type of OCD and meet the safety and medication rules, you may be able to join and see whether this targeted treatment reduces symptoms.
Belmont, MassachusettsAges 18–55 - NCT06346301Recruiting

Montreal, QuebecAges 18 years+ - NCT07805200Recruiting
Brain stimulation for obsessive-compulsive disorder
This study tests a new type of brain stimulation called transcranial temporal interference stimulation (tTIS) to see if it helps reduce OCD symptoms. It uses gentle electrical currents to target brain areas linked to OCD, and the researchers will also scan your brain to understand how it works.
Hefei, AnhuiAges 18–65 - NCT06542224Recruiting
Finding Brain Signals to Guide OCD Deep Brain Stimulation
This study is testing whether brain signals measured during deep brain stimulation (DBS) can help doctors better treat Obsessive-Compulsive Disorder. It may offer a new way to personalize treatment for people with severe, treatment-resistant OCD.
Chengdu, SichuanAges 18–65 - NCT06566781Recruiting
OCD and Learning: A Brain Study
This research study uses a computer learning task to understand how the brain's decision-making areas work in people with OCD. It may help improve treatments by showing how your orbitofrontal cortex (a part of the brain involved in learning and choices) responds.
LisbonAges 18–65 - NCT07774481Recruiting
Anxiety skills study for Ohio residents
This study tests an anxiety management program that you can use on your smartphone. It aims to help reduce anxiety symptoms and improve daily functioning.
Columbus, OhioAges 18 years+ - NCT07763977Enrolling by invitation
Vitamin D and iron study for obsessive-compulsive disorder
This study tests whether vitamin D and iron levels affect brain function linked to self-control in people with OCD. It may help find new ways to improve treatment.
Guangzhou, GuangdongAges 14–45 - NCT06494735Recruiting
French self-help book program for OCD symptoms
This study tests a French self-help book program designed to help people with OCD change how they think about their obsessions. If you have OCD and your medication has been stable for 3 months, you may be able to join.
NiceAges 18 years+ - NCT06621381Recruiting
Intensive OCD therapy for children
This study tests whether an intensive, short-term version of exposure and response prevention therapy can help children with OCD. It focuses on providing treatment in fewer, longer sessions.
Uppsala, Region UppsalaAges 6–12 - NCT07725926Recruiting
Combining therapy techniques for tic-like OCD
This study tests a therapy that combines two approaches—one for tics and one for OCD—to help people whose OCD feels like it's linked to tics. The goal is to see if this combined treatment reduces distressing urges and repetitive behaviors.
London, LondonAges 18–65 - NCT06628752Recruiting
Deep brain stimulation for severe OCD
This study tests a treatment called deep brain stimulation (DBS) for people with severe OCD that hasn't improved with standard therapies. DBS uses a device to send small electrical pulses to specific parts of the brain to help control symptoms.
Umeå, Västerbotten CountyAges 18–65 - NCT07704632Recruiting
Focused ultrasound helmet for severe OCD
This study tests whether a special helmet that uses focused ultrasound can safely change brain activity in adults with severe OCD that hasn't improved with other treatments. It may offer a new option for people who have not found relief from medications or therapy.
Toronto, OntarioAges 18–85 - NCT07701616Recruiting
Digital mindfulness therapy for obsessive-compulsive disorder

Istanbul, IstanbulAges 18–65 - NCT07587112Recruiting
TMS treatment for OCD: brain imaging study
This study tests whether repetitive transcranial magnetic stimulation (rTMS) can help people with OCD. You will get rTMS while having brain scans (PET and MRI) to see how it affects your symptoms. It's a chance to learn more about your OCD and possibly find relief.
TaipeiAges 18–65 - NCT07561528Recruiting
Brain Stimulation for Hard-to-Treat Obsessive-Compulsive Disorder

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.
