Study genes behind rare, genetic-looking illnesses
This study is trying to find the gene or body-process cause of rare diseases (or rare forms of common diseases) when the reason is not yet understood. If you qualify, you may be asked to give genetic and health information that could help doctors diagnose and understand the condition better.
DijonAges Any age - NCT05619900Recruiting
Register people with lysosomal storage diseases
This study is a registry that collects information from people diagnosed with lysosomal storage diseases. It helps researchers better understand these conditions and support future studies.
San Francisco, CaliforniaAges Up to 64 years - NCT05477563RecruitingPhase 3
One-time gene therapy for severe sickle cell and transfusion anemia
This trial tests a single dose of gene therapy (CTX001) to improve outcomes for people with severe sickle cell disease or transfusion-dependent beta-thalassemia. It aims to see how well it works and whether it is safe, especially after a planned stem cell transplant process.
New York, New YorkAges 12–35 - NCT05473637Recruiting
Study causes of small vessel brain disease in stroke and memory issues
This trial looks at people who may have “small vessel” problems in the brain, which can cause stroke, memory trouble, walking changes, movement symptoms, or headaches. It may help researchers better understand the genetic and non-genetic causes, which could improve future diagnosis and treatment.
TaipeiAges 18 years+ - NCT05357612RecruitingPhase 4
PET scan study for brain serotonin in neurodegenerative diseases
This study uses a special PET brain scan tracer to better understand serotonin receptor activity in people with certain neurodegenerative conditions, especially when they develop hallucinations or delusions. The results may help researchers improve how these brain changes are measured and tracked over time.
Nashville, TennesseeAges 50–85 - NCT05318196Recruiting
Predict kidney disease risk and progression from patient data
This trial looks at ways to predict how kidney disease may develop, change, or cause complications using information from patients. It may help doctors identify people at higher risk and tailor care earlier.
ToulouseAges 18–99 - NCT05213598Recruiting
Biomarker study for liver disease after Fontan surgery
This study looks for blood and/or test markers that can better show how severe liver disease is in people who had the Fontan heart procedure. It also involves medical imaging and/or a liver biopsy or related procedures to help evaluate those markers.
Bethesda, MarylandAges 18–100 - NCT05236595Enrolling by invitation
Personalized study for rare genetic diseases using genetic “target” drugs
This study looks for rare genetic conditions where a personalized genetic medicine (an antisense drug) could potentially work. If the team finds a “targetable” DNA or RNA change in your family, you may be followed to see how the best therapy could be planned.
Scottsdale, ArizonaAges Any age - NCT05044273Recruiting
Study of two new stents and their safety in adults

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,546 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.
