Boston, MassachusettsAges 20–79 - NCT07777445Recruiting
Oxygen treatment during exercise for lung and pulmonary vascular disease
This study compares breathing normal air versus low-flow liquid oxygen during exercise to see if oxygen helps improve performance in people with conditions affecting the lungs or the blood vessels in the lungs. You would exercise while using a portable oxygen device and then without it to compare the effects.
Zurich, Canton of ZurichAges 18 years+ - NCT06501222Recruiting
Remote ischemic preconditioning for kidney protection in CKD
This study tests whether a simple, non-invasive treatment called remote ischemic preconditioning (RIC) can help protect the kidneys of people with chronic kidney disease. RIC involves briefly restricting blood flow to one arm using a blood pressure cuff, which may trigger the body's own protective response.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07775235Recruiting
Treatment outcomes for muscle inflammation with rapid lung disease
This study looks at how well treatments work for people with muscle inflammation (myositis) that causes a fast-progressing lung condition. It may help doctors find better ways to manage this serious combination.
SingaporeAges 21 years+ - NCT07754721Recruiting
Diet and lifestyle program for chronic acid reflux
This study tests a comprehensive program that combines diet and lifestyle changes to help people with chronic acid reflux (heartburn, acid regurgitation, or chest pain) feel better. It looks at how these changes can improve your overall health and reduce symptoms.
Hualien City, TaiwanAges 18–79 - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 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.
