This study uses special kidney imaging to look for patterns that can predict how diabetic kidney disease may progress. It may help researchers find better ways to identify people at higher risk using noninvasive (and possibly biopsy-related) tests.
TurkuAges 18–80 - NCT01384721Recruiting
CT scan study for heart artery disease risk
This study uses a CT heart scan (with a calcium score) to better understand risk in people with suspected coronary artery disease. You may be asked to have scan-based measurements and then be followed for at least a year.
Milan, MIAges 18 years+ - NCT04220047Recruiting

Guangzhou, GuangdongAges 18–80 - NCT02800395Recruiting
Study links brain changes to diet and blood markers in Alzheimer’s
This study looks at how diet-related and blood “stress” markers relate to how thinking and memory decline over time in people with Alzheimer’s. It may help researchers find useful biomarkers to better track progression and guide future care.
Pierre-BéniteAges 55 years+ - NCT04617184Recruiting
Join an inflammatory bowel disease registry and sample bank
This study asks people with known or suspected inflammatory bowel disease to enroll in a registry and biorepository. It helps researchers better understand the condition using health information and stored biological samples.
Austin, TexasAges 18–100 - NCT04903912Recruiting
Study of people with blocked blood vessels or aneurysms
This registry study follows people with peripheral artery disease (blocked leg arteries), certain carotid artery narrowing, or an abdominal aortic aneurysm. It may help doctors better understand these conditions and improve care over time.
NaplesAges 18–90 - NCT04954404Recruiting
Mitral valve procedure registry for Chinese patients in one center
This study is a registry (a way to track real-world outcomes) for people with mitral valve disease who receive a mitral valve procedure. It helps doctors understand how well these procedures work and what complications happen in patients like you.
Hangzhou, ZhejiangAges 18 years+ - NCT04962295Recruiting
Brain MRI study for small blood vessel changes
This study builds a brain imaging biobank for people with “small blood vessel disease” seen on MRI. Your MRI results can help researchers better understand these changes and track new events over time.
BeijingAges 18 years+ - NCT03011697Recruiting
Heart valve disease registry for adults
This study enrolls adults in the hospital with certain heart valve problems to track their health over time. It may help doctors better understand how valve disease behaves and what outcomes look like in real life.
Hangzhou, ZhejiangAges 18 years+ - NCT04965545Recruiting
Tests for diagnosing Wilson disease using special lab findings
This trial is for people who already have a genetic diagnosis of Wilson disease. It looks at whether specific lab tests and a physical eye finding can help confirm and support the diagnosis.
Hangzhou, ZhejiangAges 6–65 - NCT01403402Recruiting
Study of congenital muscle disease patients and their families
This trial collects health information from patients with certain inherited (genetic) muscle diseases and from their families. It may help researchers better understand the disease and improve care by learning what symptoms and treatments patients experience over time.
Lakewood, CaliforniaAges Any age - NCT05002166Recruiting
Study of children with inflammatory bowel disease risks
This study looks at the typical features and risk factors in children diagnosed with inflammatory bowel disease (IBD). It may help families understand what affects IBD in kids, even if it is not testing a new treatment.
AsyutAges Up to 18 years - NCT05025254Recruiting
Online thinking tests for people with Parkinson’s disease
This study tests online “thinking” (cognitive) abilities in people with Parkinson’s disease. It may help researchers better understand how thinking changes over time and how tests can be done from home.
Montreal, QuebecAges 45–90 - NCT05078814Recruiting
Survey of a heart and leg condition’s gene differences
This study collects information to understand how often certain genetic variants (ALDH gene family) show up in people with blocked leg arteries or an acute heart condition. The results may help researchers better understand the biology behind these illnesses.
TainanAges 20 years+ - NCT04529629Recruiting
Tests and tracks treatment for adrenal hormone tumor diseases
This trial studies how adrenal hormone tumor diseases should be diagnosed, treated, and followed over time. It may help people get more precise care and better prediction of outcomes, but it has specific health and medication requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT03788512Recruiting
Registry study for recent stroke/TIA with heart artery disease
This study enrolls people who recently had an ischemic stroke or a TIA (a “mini-stroke”) and also have evidence of narrowed heart arteries. It collects information to better understand how brain and heart artery disease occur together and may guide future care.
Beijing, BJAges 18–85 - NCT02808572Recruiting
Blood and urine tests to study heart risk in kidney disease
This study looks for new markers in blood or urine that may help explain heart (cardiovascular) risk in people with chronic kidney disease. It may help doctors better predict risk, especially in those not yet on dialysis.
MontpellierAges 18–95 - NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.
ÖrebroAges 18–65 - NCT04544527Recruiting
Study risks for heart disease in older people with diabetes
This study follows older adults with diabetes to understand what factors may raise the risk of heart disease. It may help doctors spot risks earlier in people like you.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,565 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.
