Recruiting studies
- NCT05209568Enrolling by invitation
Study of immune reactions after eating gluten
This study looks at how your immune system responds when you eat gluten, including for people with celiac disease. You may be asked to follow a gluten-free diet first and then safely reintroduce gluten so researchers can measure immune changes.

Long-term study of ralinepag for pulmonary hypertension
This study follows people with pulmonary arterial hypertension (PAH) to see how safe and effective ralinepag is over the long term. It may help your care team understand what to expect from continued treatment and monitoring.
Phoenix, ArizonaAges 18 years+ - NCT03233646Recruiting
Retina scans in memory and nerve disorders
This study uses pictures of the back of your eye (retinal imaging) to look for differences in people with neurodegenerative diseases and compares them with people without these conditions. It may help researchers understand eye changes that could connect to brain or nerve health.
Durham, North CarolinaAges 18 years+ - NCT02795052Recruiting
Stem cell treatment trial for nerve injury
This study tests whether bone-marrow stem cells can improve nerve function in people with nerve damage that usually doesn’t recover with current care. It also checks whether the treatment is safe and whether people can be followed over time with repeated nerve exams.
Westport, ConnecticutAges 18 years+ - NCT00001405Recruiting
Blood Cell Collection Study for Immune and Blood Disorders
This study collects blood cells and bone marrow from people with immune system or blood disorders, and from healthy volunteers. Researchers will study these cells and may convert them into special stem cells (iPS cells) to better understand diseases and develop treatments.
Bethesda, MarylandAges 18–70 - NCT00001184Recruiting
Studying the immune system in Crohn's and colitis
This study collects blood and tissue samples to better understand how the immune system behaves in people with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. It aims to advance research rather than test a specific new treatment, and it also enrolls healthy volunteers for comparison.
Bethesda, MarylandAges 1 day–75 years - NCT07619547Recruiting
Bowel disease immune system study
This study is looking at how the immune system works in people with inflammatory bowel disease (IBD), which includes conditions like Crohn's disease and ulcerative colitis. By comparing blood or tissue samples from people with and without IBD, researchers hope to find better ways to treat the disease in the future.
Bethesda, MarylandAges 18–85 - NCT03197363Enrolling by invitation
Long-term study of adults living in Białystok
This study follows adults living in Białystok over time to learn about health and life patterns. If you’re invited to take part and agree, it may help researchers better understand community health.
BialystokAges 20–80 - NCT03019757Recruiting
Testing ways to tell dementia causes apart
This study looks at how to distinguish Alzheimer’s disease, Lewy body dementia, and Parkinson’s disease when someone has memory and thinking problems. It may help doctors choose the most accurate diagnosis and treatment path for the right condition.
Columbus, OhioAges 18 years+ - NCT07835828Recruiting
Optimised heart and kidney protection for chronic kidney disease and heart disease
This study tests a new approach to protect the heart and kidneys in people with both chronic kidney disease and heart or blood vessel problems. By optimising treatment, researchers hope to reduce the risk of further kidney or heart damage.
SvendborgAges 18 years+ - NCT03362164Recruiting
Studying heart involvement in people with Fabry disease
This study looks at how the heart is affected in adults with Fabry disease. It may help doctors better understand heart-related changes in order to guide care.
Würzburg, BavariaAges 18 years+ - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT05834855RecruitingPhase 3
Rituximab versus ocrelizumab for relapsing multiple sclerosis
This Phase 3 trial compares two similar immune therapies—rituximab and ocrelizumab—to see if rituximab works about as well for relapsing multiple sclerosis. It may help you and researchers understand which option is equally effective and safe for preventing relapses and disease activity.
AmsterdamAges 18 years+ - NCT05440240RecruitingPhase 4
Needling and possibly steroid shot for Dupuytren’s hand tightness
This trial tests a minimally invasive procedure that uses a needle to release tight tissue in the hand, and may include a steroid injection. It aims to improve hand finger straightening for people with Dupuytren’s contracture.
SilkeborgAges 45–99 - NCT05886114Recruiting
Lifestyle program to help older adults at risk of memory decline
This trial tests a multi-part lifestyle program to help older adults who may be starting to decline in thinking and memory. It may help slow cognitive decline by combining lifestyle changes over 24 months.
Hangzhou, ZhejiangAges 60–80 - NCT03225586Recruiting
Study of health differences in urban and rural communities
This study enrolls consenting adults to understand how health differs between people living in cities versus rural areas. Your participation may help researchers learn what factors influence health over time.
Rosario, Santa Fe ProvinceAges 35–70 - NCT06310148Recruiting
Preventing chronic disease in Hong Kong adults aged 45+
This study looks at a new program in Hong Kong that helps people without diabetes or hypertension learn how to prevent or manage chronic diseases. One group gets extra support through a local health centre, and the other group follows usual care.
Hong KongAges 45 years+ - NCT06439355Recruiting
Taste test for Parkinson's and Lewy body disease
This study measures how well people with Parkinson's or Lewy body disease can taste, using a special test. It aims to understand if taste problems are linked to these conditions and could help with earlier diagnosis.
DijonAges 18 years+ - NCT06383208Recruiting
Heart and kidney risk study for people with both diseases
This study looks at how well we can predict heart and kidney problems in people who have both coronary heart disease and chronic kidney disease. By analyzing certain markers, researchers hope to create a better risk assessment tool.
Beijing, Beijing MunicipalityAges 18–80 - NCT06083168Recruiting
Heart disease in chronic kidney disease study
This study is looking at the link between kidney disease and heart disease. It aims to understand how heart problems affect people with chronic kidney disease. The trial does not test a new drug, but rather follows patients to learn more about their health.
OlsztynAges 18 years+ - NCT06051253RecruitingPhase 4
Personalized infliximab dosing for active Crohn's fistulas
This study tests whether adjusting the dose of infliximab (a biologic medicine given by IV) based on drug levels in your blood works better for treating draining fistulas caused by Crohn's disease. It is for people who have not tried other biologics and whose fistulas have not healed with usual treatments.
SeoulAges 19–80 - NCT07843004Recruiting
AI screening for undiagnosed heart valve disease
This study tests whether an artificial intelligence (AI) tool can help find people who have undiagnosed heart valve problems by analyzing their electrocardiogram (ECG) results. If you visit the emergency room and have an ECG, the AI might help identify if you need further heart tests.

Visual hallucinations in Lewy body diseases
This study looks at why some people with Lewy body diseases (like Parkinson's or dementia with Lewy bodies) see things that aren't there. It uses brain scans and tests to learn more, which might help improve future care.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,353 recruiting disease 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 disease 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 disease 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.
