Sirolimus-coated balloon for heart artery branch blockages
This trial tests a new balloon coated with sirolimus (a drug that helps prevent re-blockage) for treating blocked arteries at branch points (bifurcations) in the heart. If you have a blocked artery at a branch point, this study may offer a way to treat the side branch without placing a stent there.

Study of HSK31858 tablets for lung mucus conditions
This trial tests an investigational tablet for people with chronic lung diseases like bronchiectasis, COPD, or asthma who produce at least 10 mL of sputum (mucus coughed up from the lungs) each day. The goal is to see if the drug safely reduces excess airway mucus.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06819917Recruiting
Liver fibrosis test study for fatty liver disease
This study is looking for new ways to detect liver scarring (fibrosis) in people with fatty liver disease (NAFLD, NASH, MASLD, or MASH). If you qualify, you will give a blood sample to help identify biomarkers that could replace biopsies.
CopenhagenAges 18–75 - NCT06816485Recruiting

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,577 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.
