MilanAges 18 years+ - NCT03394313Recruiting
Registry study for people with new heart disease and type 2 diabetes
This study records health information to understand how type 2 diabetes and newly diagnosed heart disease affect people over time. It may help doctors learn what to watch for and how to plan care, though it is mainly an observational registry.
DohaAges 18 years+ - NCT03418441Recruiting
Study infections of the brain and spinal fluid in Denmark
This trial focuses on people in Denmark who may have an infection in the brain or the fluid around the brain and spinal cord. Researchers aim to collect and compare diagnostic results for different infection types (viral meningitis, bacterial meningitis, encephalitis, and others) to help confirm the cause and guide care.
AalborgAges 18 years+ - NCT03428048Recruiting
NEXUS Registry for coronary artery disease or Afib patients
This is a research registry that collects health information about people with coronary artery disease or Afib. It may help doctors and researchers better understand these heart conditions and improve future care.
Glenwood Springs, ColoradoAges 18 years+ - NCT03434548Recruiting
Imaging study for early and late Huntington’s disease changes
This study uses repeat brain scans (including PET and MRI) to track changes in the brain caused by Huntington’s disease over time. It may help researchers understand disease progress and test how well the scans reflect early vs later disease.
London, EnglandAges 21–75 - NCT03443999Recruiting
Registry to follow patients with a sirolimus stent
This study is a follow-up registry that tracks how people do after doctors place a specific type of drug-eluting coronary stent. It may help doctors understand safety and outcomes of the Supraflex stent in real-world care.
Breda, North BrabantAges 18 years+ - NCT03445585Recruiting
Biobank study for primary sclerosing and primary biliary cholangitis
This study collects and stores samples from people with PSC (primary sclerosing cholangitis), PBC (primary biliary cholangitis), and some related liver conditions. Researchers use these samples to better understand these diseases and support future research.
Rochester, MinnesotaAges 18–85 - NCT03455478Recruiting
Study of adult vision health in Shanghai residents
This study looks at the eye health of adults who live in Shanghai. It may help researchers understand vision problems in the local population and improve future eye care.
Shanghai, Shanghai MunicipalityAges 18–100 - NCT03470246Recruiting
Wearable activity coaching after heart surgery
This study tests a personalized activity program and coaching after heart surgery, using wearable sensors to track movement. It may help you recover more safely and move in a goal-directed way during rehabilitation.
KuopioAges 30–90 - NCT03473912Recruiting
Rheumatoid disease biobank study for adults
This study asks adults with a rheumatoid condition to join a biobank, which is a safe place to store health information and biological samples for future research. It may help researchers better understand rheumatoid conditions and develop better treatments.
Kfar SabaAges 18–120 - NCT03474029RecruitingPhase 2/Phase 3
Daily rifapentine treatment test for latent tuberculosis infection
This trial studies whether taking rifapentine every day is safe and helps prevent active tuberculosis (TB) in people who have latent TB infection. It aims to find the best way to stop TB from becoming a serious illness later.
Denver, ColoradoAges Any age - NCT03480568RecruitingPhase 3
A cholesterol injection study for people on dialysis
This study tests whether a cholesterol-lowering injection (alirocumab) helps people who are on regular dialysis. It aims to improve cholesterol control in a carefully selected group and tracks safety during treatment.

- Yes. Clin2 currently lists 10,808 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.
