Register people with diagnosed ADPKD to build a kidney data resource
This trial builds a secure database by collecting information from adults who already have autosomal dominant polycystic kidney disease (ADPKD). Your information can help researchers understand the condition better and improve future care.
New York, New YorkAges 18 years+ - NCT03797183Recruiting
Check heart and lung function using a painless chest scan
This study uses a noninvasive scan that measures electrical signals across the chest to better understand breathing and heart-related circulation problems. It may help doctors learn what to monitor and how conditions like lung/airway pressure and vessel narrowing progress.
Aurora, ColoradoAges 2 weeks–40 years - NCT06033924Recruiting

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,612 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.
