Recruiting studies
- NCT06376279Enrolling by invitation
Genetic testing for metabolic diseases
This trial uses genetic testing to find the cause of suspected metabolic diseases, including some cases of epilepsy. It may help you get a clearer diagnosis and guide treatment.
Ages Any age - NCT06294964Enrolling by invitation
Sleep and heart health study for older adults
This study looks at how sleep patterns affect the risk of heart disease and stroke in older adults. It aims to help improve heart health through better sleep.
ShanghaiAges 60–120 - NCT06253507Enrolling by invitationPhase 1/Phase 2
Gene therapy for p47 chronic granulomatous disease
This trial tests a new gene therapy for people with a specific type of chronic granulomatous disease (p47 CGD). The treatment uses your own blood stem cells, which are modified in a lab to help your body fight infections better. It is for people who do not have a matched stem cell donor and have had serious infections.
Bethesda, MarylandAges 3–65 - NCT05979870Enrolling by invitation
AI-enhanced heart MRI for valve disease
This study uses artificial intelligence to improve MRI scans for people with aortic or pulmonary valve disease who are scheduled for valve surgery or a non-surgical valve procedure. It aims to help doctors better assess heart function before treatment.
Gothenburg, GothenburgAges 1 week–18 years - NCT05932615Enrolling by invitation
Testing a new transcatheter valve for aortic valve narrowing
This trial studies how safe and effective the NAVITOR valve is for treating narrowed aortic valves placed through a catheter (no open-heart surgery). It may be an option if you’re at intermediate-to-low surgical risk and meet heart ultrasound/CT measurements.
Birmingham, AlabamaAges 18 years+ - NCT05870007Enrolling by invitationPhase 2
Atorvastatin and alkalizing treatment for autosomal dominant PKD
This Phase 2 study tests whether atorvastatin plus an “alkalizing” treatment (sodium bicarbonate) can slow or improve disease effects in people with autosomal dominant polycystic kidney disease (ADPKD). It specifically targets metabolic acidosis (when the body becomes “too acidic”), which may worsen kidney health.
New Taipei CityAges 18 years+ - NCT05775354Enrolling by invitation
Early heart disease check-in in adults age 50–80
This study aims to improve early detection of heart and blood vessel problems by adding further research after routine care. It may help you by making sure your heart risk is monitored more closely, if you’re eligible and agree to the additional steps.
UtrechtAges 50–80 - NCT05727852Enrolling by invitation
Breath and heart tests to study lung disease stiffness
This study uses breath analysis and heart/electrical heart testing to look at how stiff the arteries are in people with long-term lung conditions. It may help researchers better understand lung disease effects on the cardiovascular system.
MoscowAges 18 years+ - NCT05514184Enrolling by invitation
Diet coaching for diabetes and kidney disease to delay dialysis
This study tests a plant-focused diet plan to help people with diabetes and moderately to severely reduced kidney function avoid or delay needing dialysis. You would get diet instructions based on your random group and have several follow-up visits and check-ins over 6 months.
Orange, CaliforniaAges 18 years+ - NCT05368038Enrolling by invitation
Newborn screening program for babies up to 4 weeks old
This trial tests a flexible newborn screening process that looks for certain conditions early in life. It may help by catching problems sooner, when treatment can be started earlier.
Brooklyn, New YorkAges Up to 4 weeks - NCT05216133Enrolling by invitation
Study WTC lung and reflux markers using noninvasive tests
This study looks at blood “biomarkers” and breathing/acid-reflux measurements in FDNY workers exposed to the 9/11 site to understand airway disease, Barrett’s esophagus, and reflux. It may help identify which people have hidden (underdiagnosed) reflux or lung involvement after 9/11.
New York, New YorkAges 37–90 - NCT05084937Enrolling by invitation
Study on celiac disease from teens into adulthood
This trial looks at how people with celiac disease transition from childhood into adulthood, using questionnaires. It also includes people without celiac disease for comparison, to help researchers understand similarities and differences during these teen years.
KuopioAges 13–19 - NCT04896138Enrolling by invitation
Natural history study for lung scarring patients
This study follows people who are being seen for lung scarring (also called ILD) and compares them with family members without lung scarring. It helps researchers better understand how this condition changes over time and what to look for in the future.
Charlottesville, VirginiaAges 18 years+ - NCT04770571Enrolling by invitation
Study of posterior neck and upper-back spine fixation systems
This trial studies specific surgical hardware used to stabilize the back of the neck and upper back during spine surgery. It may help surgeons compare outcomes for people needing fixation for trauma, instability, failed prior fusion, tumors, or certain degenerative conditions.
Orange, CaliforniaAges 18 years+ - NCT04701177Enrolling by invitation
Smartphone-based study of brain biomarkers in memory clinic patients
This observational study follows people with (or at risk for) Alzheimer’s-related brain changes and a comparison group without them. It uses clinic visits, cognitive testing, questionnaires, and possibly a spinal fluid test to better understand brain biomarkers and how they relate to thinking and daily life.
Corfu, CorfuAges 45 years+ - NCT04646187Enrolling by invitationPhase 4
Lowering biologic doses for Crohn’s and ulcerative colitis
This trial tests whether people with Crohn’s disease or ulcerative colitis who are currently well-controlled can safely use less-frequent anti-TNF medicine. It may help reduce treatment intensity while keeping inflammation under control.
GhentAges 12–25 - NCT04208529Enrolling by invitationPhase 3
Long-term follow-up after receiving CTX001 infusion
This study follows people for a long time after they received CTX001 in an earlier (parent) study. It helps researchers learn about long-term safety and outcomes of the treatment.
Palo Alto, CaliforniaAges 2 years+ - NCT03369353Enrolling by invitation
Personalized immune testing study for bowel and transplant patients
This study looks at whether a precise lab test can help understand inflammatory bowel disease, functional gut disorders, and immune changes after stem cell transplant or cell therapy. It may help doctors choose better monitoring and treatments based on your immune and gut test results.
Boston, MassachusettsAges Any age - NCT03136731Enrolling by invitation
Screening strategies for celiac disease in families and patients
This study tests practical, evidence-based screening approaches for celiac disease—either for family members of people with celiac disease or for people who already have it diagnosed. It may help improve how celiac disease is checked earlier and more accurately.
TampereAges 6 months–100 years - NCT07800247Recruiting

Comparing blood thinners after a heart attack
This study compares two ways to lower the chances of another heart attack: taking the standard medicine (clopidogrel) versus taking a combination of aspirin and a lower dose of a blood thinner (rivaroxaban). If you join, you'll be assigned to one of these options to see which works better for people like you.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,803 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.
