Recruiting studies
- NCT03821857RecruitingPhase 4
Study of hormone disruption effects on aging and Alzheimer’s
This trial studies how hormone (endocrine) disruption may affect aging and Alzheimer’s disease in women. It may help researchers understand why these effects can differ by sex and how to better assess or track risk over time.
Jacksonville, FloridaAges 60 years+ - NCT03867448Recruiting
Study of Hormone Conditions and How the Body Works
This study looks at people with known or suspected hormone (endocrine) conditions. It aims to improve understanding and clinical screening so doctors can better manage these conditions over time.
Bethesda, MarylandAges 18–90 - NCT07247279Recruiting
Study of myasthenia gravis treatments in Russia
This study tracks how generalized myasthenia gravis (a condition that causes muscle weakness) is treated in Russia. By looking at real-world data, researchers hope to learn more about which treatments work best for people like you.
Kazan'Ages 18 years+ - NCT06969807RecruitingPhase 2
Stem cells for diabetic kidney disease
This trial tests whether a type of stem cell called mesenchymal stromal cells (Amimestrocel) can help people with diabetic kidney disease. It aims to see if the treatment is safe and can improve kidney function.
Beijing, Beijing MunicipalityAges 18–80 - NCT05904132Recruiting
Brain stimulation therapy for early Alzheimer’s memory loss
This trial studies a “closed-loop” brain stimulation approach to improve symptoms in people with early Alzheimer’s-related memory problems. It may help by delivering stimulation based on your brain signals, if you meet the safety and diagnosis requirements.
Charlestown, MassachusettsAges 50–80 - NCT04178408Recruiting
IBD family and neighborhood health registry study
This study builds a health registry for people with inflammatory bowel disease (IBD) and compares them with healthy family and neighborhood controls. It may help researchers better understand IBD in sub-Saharan African communities.
HarareAges Any age - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.
Culver City, CaliforniaAges 18 years+ - NCT04774159RecruitingPhase 3
Low-dose colchicine to lower risk in leg artery disease
This trial tests whether low-dose colchicine can reduce “residual” risk—future heart and blood-vessel problems—in people with peripheral artery disease (PAD). It targets PAD symptoms and complications like poor blood flow in the legs, even after certain procedures.
New Haven, ConnecticutAges 18 years+ - NCT04844944Recruiting
Heart registry for adults with heart failure, CAD, or atrial fibrillation
This is a hospital-based study that collects standardized information about adults with specific heart conditions—heart failure, coronary artery disease, or atrial fibrillation. It may help doctors and researchers better understand these diseases and improve future care.
BerlinAges 18 years+ - NCT04873258Recruiting
Test a non-invasive tool to screen for fat-related liver disease
This study looks at a new non-invasive screening method to predict metabolic dysfunction–associated steatotic liver disease (MASLD), a condition where fat builds up in the liver. The goal is to help identify people who may be at risk without needing invasive tests.
London, LondonAges 18–80 - NCT05250557Recruiting
Study heart blood-flow measurements to predict outcomes in coronary disease
This study looks at a specific heart blood-flow measurement taken during a coronary procedure to see how well it predicts future outcomes. If you had a successful pressure measurement called FFR with a tracing, your results may be analyzed to understand risk and prognosis.
SeoulAges 20 years+ - NCT05287750Recruiting
Brain disease study using 7.0T brain MRI scans
This study looks at people with brain conditions using a very strong MRI scanner (7.0T). It may help doctors understand brain diseases better and improve how scans are used, but you must be able to safely have the MRI (and possibly contrast dye).
BeijingAges 18–80 - NCT05389956Recruiting
Study links health screening results to heart and cancer risk
This study follows people who had a routine health check to learn what increases the risk of heart disease and cancer. Your answers and test results may help doctors better understand risk factors in the Korean population.
UlsanAges 19 years+ - NCT05417776RecruitingPhase 2
PET scan test for early lung scarring
This trial uses a special PET/MRI scan to look for early signs of lung scarring and inflammation using a “collagen-targeting” tracer. It may help doctors better identify early interstitial lung disease (IL D) and track it over time.
Boston, MassachusettsAges 40 years+ - NCT05432635RecruitingPhase 1
CAR T-cell and vaccine treatment after stem cell transplant
This Phase 1 study tests a customized immune-cell treatment (CAR T-cells) plus a vaccine given after stem cell transplant for certain aggressive B-cell non-Hodgkin lymphomas. It aims to help your immune system better recognize and attack the lymphoma and to see how safe the approach is.
Duarte, CaliforniaAges 18 years+ - NCT05502965Recruiting
Diet pattern trial for Crohn’s after bowel surgery
This study tests whether a specific diet after Crohn’s surgery can help you recover and stay well. It compares outcomes in people who can follow an exact diet plan after bowel resection.
Hangzhou, ZhejiangAges 14 years+ - NCT05525507RecruitingPhase 1
Test early immune-tolerance treatment for matched kidney transplant patients
This Phase 1 study tests a treatment plan given after a kidney transplant to help the immune system stay calm and reduce the risk of rejection. Participants must have a well-functioning kidney transplant from a closely matched living donor and meet health and safety requirements.
Los Angeles, CaliforniaAges 18 years+ - NCT05549752RecruitingPhase 3
Flecainide vs amiodarone to treat fast heart rhythm in ER
This trial compares two medicines—flecainide and amiodarone—to help restore normal rhythm during an emergency visit for paroxysmal atrial fibrillation (a-fib). It’s aimed at people who also have coronary artery disease but no ongoing (residual) heart ischemia, and who have enough heart pumping strength.
AthensAges 18–85 - NCT05550714Recruiting
Choosing anesthesia type during deep brain stimulation for Parkinson’s
This study compares different anesthesia choices during deep brain stimulation surgery for Parkinson’s disease, using a technique that guides electrode placement. It may help your care team choose the safest and most comfortable anesthesia approach for surgery.
BeijingAges 50–80 - NCT05554224Recruiting
Personalized treatment based on obesity-related fatty liver tests
This study uses multiple types of health data (“multi-omics”) to help choose a personalized treatment plan for people with obesity-related fatty liver disease. It may help match treatment to your biology to improve outcomes.
Reus, TarragonaAges 18 years+ - NCT05578495Recruiting
Track daily movement to predict future health problems
This study looks at how active versus sedentary you are (often using a digital signature from your daily routine) to see how it relates to developing multiple health conditions over time. It may help researchers understand which activity patterns are linked with higher risk, especially in certain long-term illnesses.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,778 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.
