Verona, VenetoAges 18 years+ - NCT07348640RecruitingPhase 3
Study of new MRI dye for blocked blood vessels
This trial tests a new MRI contrast dye (gadopiclenol) to see if it works as well as the standard dye for finding blocked or narrowed blood vessels. If you have symptoms of vascular disease, you may be able to join and help compare the two dyes.

Study of EBV-positive T/NK-cell lymphoma and related diseases
This study collects medical information and blood samples from people with Epstein-Barr virus-positive T/NK-cell lymphoproliferative diseases to better understand how these conditions progress and respond to treatment. It includes a retrospective part (looking back at medical records) and a prospective part (following people forward in time).
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT00344188Recruiting
Study of Leishmania infections
This trial studies people with Leishmania infections (a parasitic disease often from sand fly bites). Researchers aim to better understand and treat the infection, and you may benefit from expert care.
Bethesda, MarylandAges 3–100 - NCT07570316RecruitingPhase 3
Testing efgartigimod for Graves' disease hyperthyroidism
This study tests whether efgartigimod, an injectable medication given under the skin, can help control overactive thyroid (Graves' disease) in adults already taking methimazole or carbimazole. The goal is to see if it reduces thyroid antibodies and improves thyroid hormone levels.
Orange, CaliforniaAges 18 years+ - NCT07535008Recruiting
Dental Cleaning to Prevent Graft-Versus-Host Disease
This study tests whether professional dental cleaning after a stem cell transplant can help prevent chronic graft-versus-host disease (GVHD), a condition where transplanted immune cells attack your body. You'll receive dental cleanings and be followed for one year to see if this simple preventive step reduces GVHD complications.
Seattle, WashingtonAges 18 years+ - NCT07754097Recruiting
Tracking your health at home for chronic kidney disease
This study tests if regularly tracking your blood pressure, diet, and medications through a mobile app can help monitor kidney disease progression. It aims to see if this self-management approach helps you stay healthier.
Daejeon, DJAges 19–84 - NCT03884075RecruitingPhase 2
Semaglutide study for fatty liver and how sugar affects the liver
This Phase 2 study tests how semaglutide (a diabetes medication also used for weight) affects fatty liver and the liver’s response to sugar. It may help people with non-alcoholic fatty liver disease understand whether the drug improves liver fat and related changes.
Bethesda, MarylandAges 18–100 - NCT04703179Enrolling by invitation
Rare disease and undiagnosed case research blood and tissue biobank
This study collects and stores samples and related medical information for people with rare diseases or suspected genetic conditions. It may help researchers better understand these conditions and develop future testing and treatments.
Scottsdale, ArizonaAges Any age - NCT05656378Recruiting
Storing samples to study how the body interacts with microbes
This study creates a storage bank of biological samples like blood, stool, and tissue. Researchers will use these samples to learn how the body interacts with the natural microbes that live in and on us, which may help improve treatments for many diseases.

Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT07748858Recruiting

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 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.
