Study of complication risks in adults without a spleen
This study looks at what factors can predict complications in people who do not have a functioning spleen, and how often those complications happen over time. It may help clinicians better identify higher-risk patients and improve care.
AngoulêmeAges 18 years+ - NCT04101188Recruiting
Study how extra potassium affects blood vessels
This study looks at how eating more potassium may protect blood vessels in healthy people. You may be eligible if you have normal blood pressure and a normal heart rhythm test, and you do not have certain health conditions.
Newark, DelawareAges 18–45 - NCT04075162Recruiting
Free heart calcium scan program at University Hospitals
This study is looking at people who already received a free coronary artery calcium (CAC) CT scan through a community screening program at University Hospitals. It may help the hospital understand who benefits from offering these no-cost scans.
Cleveland, OhioAges 18–100 - NCT03635541Recruiting
Liver health changes in fatty liver disease
This study tracks how liver scarring (fibrosis) and fat buildup (steatosis) change over time in people with nonalcoholic fatty liver disease (NAFLD). It helps doctors understand risk factors so they can better predict and manage the disease.
Beijing, Beijing MunicipalityAges 18–70 - NCT03480633Recruiting
Heart failure precision medicine registry
This registry collects health and heart-related information to better understand heart failure (with preserved or reduced pumping strength) and guide more precise care. You may be asked to share tests and results, and help researchers learn which patterns match different types of heart failure.
Boston, MassachusettsAges 18 years+ - NCT03450603Recruiting
Predicting COPD flare-up risk in adults
This study looks at factors that can predict when chronic obstructive pulmonary disease (COPD) will flare up. It may help doctors identify people at higher risk sooner and tailor care to prevent flare-ups.
ShanghaiAges 40 years+ - NCT03089827Enrolling by invitation
Tests how a brain imaging tracer spreads in Alzheimer’s risk
This trial uses a radioactive imaging tracer to see how it moves and settles in the brain in people with risk factors for Alzheimer’s disease. It may help researchers understand which people show tracer patterns linked to Alzheimer’s changes.
Winston-Salem, North CarolinaAges 55 years+ - NCT03206372Recruiting
Study of blood clot risk during hormone use in families
This study looks at what increases the risk of deep vein thrombosis or a lung blood clot (venous thromboembolism) in women who are using hormones. Researchers compare close family members to understand inherited risk and hormone-related triggers, which may help with prevention in the future.
BrestAges 16 years+ - NCT03083405Enrolling by invitation
Study of tooth grinding during sleep
This study is for adults who have been diagnosed with sleep bruxism (tooth grinding during sleep). Researchers want to understand it better using sleep testing, and it may help refine how this condition is evaluated.

Common questions
- Are there clinical trials for risk factors?
- Yes. Clin2 currently lists 344 recruiting risk factors 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 risk factors 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 risk factors 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.
