Collecting and following up on endocrine disease at MD Anderson
This study gathers medical information from people being seen for thyroid, parathyroid, or adrenal conditions at MD Anderson and checks in over time. It also asks family members of participants who pass away for permission to learn the cause of death, which may help researchers understand links to endocrine disease.
Houston, TexasAges Any age - NCT03626480Recruiting
Nutrition support before and after heart surgery for babies
This trial studies a nutrition plan given around the time of heart surgery for babies with congenital heart disease. It may help improve how babies grow and recover by supporting feeding before and after the operation.
Hangzhou, ZhejiangAges 1 day–1 year - NCT03929887Recruiting
Kidney biopsy patients join a kidney tissue research bank
This study builds a kidney tissue “library” to help researchers analyze kidney disease in newer ways. It may help by improving how glomerular (kidney filter) diseases are understood over time, using samples from people who already had a biopsy.
ChuncheonAges Any age - NCT04340817Recruiting
Study of fatty liver in Nordic countries
This study looks at people with non-alcoholic fatty liver disease (fat buildup in the liver without heavy alcohol use). It may also include healthy volunteers for comparison, helping researchers understand the condition better.
Hvidovre, Capital Region DenmarkAges 18 years+ - NCT04371042Recruiting
Study of liver disease and genes in people with fatty liver
This study collects information about metabolic and unexplained (cryptogenic) liver disease and looks at “omics” tests, which are lab tests that measure patterns in blood or tissue to learn what drives the disease. It may help researchers better understand fatty liver and related serious complications, like liver scarring and liver cancer.
Roma, Rome/lazio/italyAges 18 years+ - NCT04190602Recruiting
Registry study for NeoChord artificial mitral valve chord
This study keeps track of people who had NeoChord treatment to help understand how well it works in everyday care. You may be included if you had a certain type of mitral valve leakage (regurgitation) and the procedure happened after 2016.
BonnAges 18 years+ - NCT03781492Recruiting
Treatment study for stable angina symptoms
This study looks at managing and treating stable angina, a type of chest discomfort that happens predictably with activity or stress. It may help find better ways to control symptoms and improve daily life, but you must not have certain recent heart events to join.

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.
