Recruiting studies
- NCT05704413Recruiting
Biobank study using gut tissue in bowel disease
This study collects and stores digestive (bowel) tissue to better understand how gut bacteria may affect diseases like ulcerative colitis or Crohn’s disease. It may help researchers find future ways to improve care for people with these conditions.

Study drug PRX-102 for Fabry disease in Japanese patients
This trial tests whether PRX-102 is safe and effective for treating Fabry disease in Japanese participants. It also measures how the drug moves through the body and affects body systems, to see if it helps your symptoms and organ function.
Chikushino-shi, FukuokaAges 13–70 - NCT05711888Recruiting
Alzheimer brain study using a memory and recognition task
This study uses a computer task to test thinking and recognition skills in people with or without Alzheimer’s disease. It also includes checking Alzheimer-related biomarkers to help researchers understand how the task connects to the disease.
Beşiktaş, IstanbulAges Any age - NCT05712395Recruiting
Pain-free exercise program for people with leg artery disease
This trial tests a new kind of exercise that is meant to be non-ischemic (not reduce blood flow) and pain-free, to see if it helps people with peripheral artery disease (PAD) who get leg pain when walking. You may be eligible if you have PAD confirmed by specific treadmill and blood-pressure measurements and meet the exercise and health safety requirements.
Oklahoma City, OklahomaAges 40 years+ - NCT05715710Recruiting
MRI and brain vein pattern study for memory and thinking problems
This study looks at whether certain deep brain veins seen on MRI are linked to thinking and memory problems in people with small-vessel brain disease. It compares brain scan findings with cognitive (thinking) testing to better understand what may drive cognitive dysfunction.
Zigong, SichuanAges 50–85 - NCT05722236Recruiting
Peer support program to help people manage stress from IBD
This trial tests a “peer-to-peer” support program to help adults with inflammatory bowel disease (IBD) manage psychological distress (stress and emotional strain). It may help you cope better during major life or treatment changes related to IBD.
Halifax, N.S.Ages 18–99 - NCT05725876RecruitingPhase 1
Imaging ustekinumab medicine movement in Crohn’s and psoriasis
This Phase 1 study uses a special camera to track how ustekinumab (a common biologic medicine) spreads in inflamed tissue. It aims to help researchers understand where the drug goes in Crohn’s disease and psoriasis, especially when standard treatments haven’t worked.
GroningenAges 18 years+ - NCT05728216Recruiting
Using a special eye-scan to study kidney biopsy samples
This study tests whether a noninvasive “eye-scan” during a kidney biopsy can help doctors tell the difference between acute kidney injury and chronic kidney disease. If it works, it may improve how kidney problems are diagnosed in routine practice.
Chalon-sur-Saône, Saône-et-LoireAges 18 years+ - NCT05728697Recruiting
Test a liver ultrasound method to measure fat and stiffness
This trial tests a special ultrasound technique during an endoscopy to see how well it can detect changes in the liver from non-alcoholic fatty liver disease. It may help improve non-invasive assessment before or alongside a follow-up liver biopsy.
Boston, MassachusettsAges 18 years+ - NCT05732727RecruitingPhase 3
Stronger BP lowering using diuretics in kidney disease
This Phase 3 trial compares a plan that uses diuretics (water pills) to lower blood pressure more, versus usual blood pressure care, in people with uncontrolled hypertension and moderate-to-severe chronic kidney disease. It may help your blood pressure control while monitoring safety closely because kidney function changes how medicines work.
AngersAges 18 years+ - NCT05732714Recruiting
Reduce heart event risk after major non-heart surgery
This study looks at ways to lower the chance of heart-related problems after major surgery that is not directly related to the heart. It focuses on people at higher heart risk who are expected to stay in the hospital for at least two days after surgery.
Toronto, OntarioAges 45–75 - NCT05732870Recruiting
Study looks for blood and gene signals that affect bone health
This study collects information and samples around the time of certain bone or joint surgeries (like joint replacement or fracture repair) to learn what factors help or harm bone healing. The results may help find better targets to improve long-term bone health and recovery.
London, Greater LondonAges 18–110 - NCT05733702Recruiting
Study of Crohn’s and ulcerative colitis treatment changes
This study follows adults with Crohn’s disease or ulcerative colitis when their treatment is changed. It collects health information and samples to better understand how treatment changes affect people over time.
LuxembourgAges 18 years+ - NCT05733832Recruiting
Transitional care after hospital discharge for serious liver disease
This trial tests an extra support program after you leave the hospital to help people with advanced liver disease avoid complications and stay on track. It may help by providing structured follow-up soon after discharge.
Chicago, IllinoisAges 18 years+ - NCT05733845Recruiting
Study of why some bowel inflammation treatments don’t work
This study looks at blood and/or tissue “molecular” (cell-level) reasons why treatments don’t fully work in adults with Crohn’s disease or ulcerative colitis. If you are starting a biologic or small-molecule medicine and still have moderate to severe symptoms, you may be able to contribute to research that helps improve future care.
Vandœuvre-lès-Nancy, CHRU de NancyAges 18 years+ - NCT05734378Recruiting
Study aims to predict outcomes in small blood vessel brain disease
This trial is looking at how brain “small blood vessel disease” changes over time and what outcomes to expect. If you have certain symptoms or scan findings from this condition, your care team may compare your prognosis to help guide future treatment planning.
BernAges 16 years+ - NCT05736419RecruitingPhase 2
Immune-suppressing treatment before stem cell transplant for blood disorders
This Phase 2 study tests an immune-suppressing treatment for people with sickle cell disease or beta-thalassemia who are preparing for a stem cell transplant from a donor. It aims to help the transplant work better by changing the immune response.
Basking Ridge, New JerseyAges 2–50 - NCT05738824Recruiting
Study how inflammatory muscle diseases naturally change over time
This study follows people with suspected or confirmed inflammatory muscle disease (and sometimes healthy adults) to better understand how the condition progresses and what changes over time. It may help researchers identify patterns that could guide future treatments.

Testing a nerve target in Parkinson’s disease
This trial is studying the “superior cervical ganglion” as a possible treatment approach for Parkinson’s disease. It may help people whose symptoms are truly caused by Parkinson’s, not by another condition.
RomeAges 30–80 - NCT05741853Recruiting
Speech therapy study for bilingual people with primary progressive aphasia
This study looks at how well speech-language therapy works in bilingual people with primary progressive aphasia, a condition that gradually affects language. It also tests whether different language skills (Spanish/Catalan or Spanish/English) affect response to treatment.
Austin, TexasAges 40 years+ - NCT05742776Recruiting
Ultrasound and sleep quality check in carpal tunnel
This trial studies whether ultrasound exam findings match how well you sleep if you have carpal tunnel syndrome. It may help doctors better understand which ultrasound results go along with worse sleep and symptoms.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 recruiting general population (no specific condition or 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 general population (no specific condition or 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 general population (no specific condition or 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.
