Recruiting studies
- NCT05264051Recruiting
MRI scan to predict outcomes in liver disease
This study looks at MRI images taken as part of routine care to see if they can help predict future health problems in people with liver disease. If you already have an MRI scheduled for clinical reasons, this may help doctors better estimate risk over time.

CT calcium scan to prevent heart problems in diabetes
This trial studies whether using a heart CT “calcium score” to guide prevention can lower the chance of major heart disease in people with type 2 diabetes who have other heart risk factors. It may help by targeting prevention more personally, based on your calcium score.
YilanAges 40 years+ - NCT05289167RecruitingPhase 1/Phase 2
Medicines to prevent graft-versus-host disease after a transplant
This trial tests a combination of medicines (post-transplant cyclophosphamide, bortezomib, and abatacept) to lower your chance of developing graft-versus-host disease (when transplanted immune cells attack your body) after a transplant. If you qualify, you’ll receive the study medicines as part of your post-transplant care and be followed closely to check safety and prevention of GvHD.

It helps researchers understand the disease and how it progresses, which can support future studies and care improvements.
LeuvenAges 12 years+ - NCT05249634RecruitingPhase 2
Testosterone treatment study for men with chronic kidney disease
This Phase 2 study tests whether testosterone therapy can help men with chronic kidney disease who have low testosterone and related symptoms. It looks to see if treatment is safe and beneficial, while carefully checking heart, blood, prostate, and clotting risks.
St Louis, MissouriAges 18–85 - NCT05208567Recruiting
Testing heart ultrasound in older adults with weak heart pumping
This trial uses a heart ultrasound test to find people who may have weak heart pumping function, especially in a multi-ethnic community. It may help improve how doctors detect this condition earlier using ultrasound images.
LondonAges 65 years+ - NCT05253560Recruiting
Study prodromal Parkinson signs in GBA1 mutation carriers
This study looks at early (before full disease) Parkinson-like symptoms in people who carry a specific genetic change called GBA1. It may help researchers understand who could develop Parkinson’s and how early signs can be tracked.
Jerusalem, Please Select...Ages 40–75 - NCT05251415Recruiting
Study of rare autoimmune diseases with blood and medical samples
This trial collects clinical and lab information (like blood and medical history) from people with rare autoimmune diseases, especially when symptoms are unusual. It aims to better understand what causes these illnesses and how newer treatments may help.
ToulouseAges 6–99 - NCT05231798RecruitingPhase 2
PET and brain scans in adults with Down syndrome
This study looks at how well a brain chemical system works in adults with Down syndrome as they age, including how it relates to Alzheimer’s-type brain changes and thinking skills. It uses brain scans and memory/thinking tests to see whether these measures can help track risk or changes over time.
Nashville, TennesseeAges 18–55 - NCT05204446Enrolling by invitation
Behavior program for teens with celiac disease
This study tests a behavioral (coaching-style) program to help teens manage celiac disease. It may help by supporting teens and their parent/guardian with habits and coping skills.
Washington D.C., District of ColumbiaAges 12–16 - NCT05205980Recruiting
Training practice to help prevent falls in Alzheimer’s
This trial tests whether a specific “training practice” can reduce falls in people with probable Alzheimer’s disease. It may help by improving safe walking and balance after doing the training.
Valdosta, GeorgiaAges 65–90 - NCT05236374Recruiting
Daily beef in a heart-healthy diet to study zinc cells
This study tests whether eating daily beef as part of a heart-healthy diet changes how your body’s cells handle zinc, a mineral important for many functions. It’s designed for older adults and includes strict diet and medication rules to keep results accurate.
Davis, CaliforniaAges 55–70 - NCT05216042Recruiting
Study of genetics and heart/metabolic health in adults
This study looks at how genetic markers (DNA) relate to heart health and “metabolic” health (how your body manages sugar and fat). You may be asked to provide genetic samples and follow study health checks and protocols to help researchers understand who is at higher risk.

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.
