Genetic testing to help identify inherited eye conditions
This study uses whole exome and whole genome genetic tests to look for DNA changes linked to inherited or congenital eye problems. It may help families and doctors better understand the cause of the eye condition and guide future care.
Bethesda, MarylandAges 1 day–120 years - NCT01451502Recruiting
Study uses donor cord blood to restore blood cell production
This study tests giving you donated umbilical cord blood through an IV to help your body rebuild blood-forming cells after chemotherapy. It may help people who need a stem-cell “reset” using a specific type of cord blood unit that meets strict matching and safety rules.
Minneapolis, MinnesotaAges Any age - NCT00920972RecruitingPhase 1/Phase 2
Bone marrow transplant prep for children with non-cancer blood disorders
This early-stage study tests a specific chemotherapy “conditioning” regimen to prepare the body for a bone marrow transplant in children with certain non-cancer blood or immune conditions. It may help the transplant work better, but it also carries risks from the chemotherapy and transplant process.
Phoenix, ArizonaAges Up to 20 years - NCT00950430Enrolling by invitationPhase 4
Brain scan study for amyloid plaques in adults
This study uses brain imaging to look for amyloid plaques (abnormal protein deposits) as people age. It may help researchers better understand how these changes develop over time.
Rochester, MinnesotaAges 30–100 - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT05902351Recruiting
Study of the natural course of Charcot-Marie-Tooth disease
This study looks at how Charcot-Marie-Tooth disease (CMT) or related inherited nerve conditions change over time. It may help researchers better understand what to expect and guide future treatments.
New York, New YorkAges Any age - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.
Sioux Falls, South DakotaAges Any age - NCT04613089Recruiting
Study of Batten disease progress and clinical changes over time
This trial tracks how Batten disease (NCL) affects the body and how symptoms change over time. If you have a confirmed genetic (molecular) diagnosis—especially CLN2 with Brineura treatment—it may help researchers understand disease patterns and care needs.
HamburgAges Any age - NCT06672237RecruitingPhase 3
Study of NTLA-2001 for hereditary ATTR amyloidosis with nerve damage
This study is testing a new gene-silencing treatment called NTLA-2001 for people with hereditary ATTR amyloidosis that causes nerve damage. It works by stopping the body from making a faulty protein that builds up and harms nerves.
Buenos AiresAges 18–85 - NCT03333200Recruiting
Study of genetic brain diseases over time
This trial follows people with genetic neurodegenerative (brain-wasting) disorders over time to better understand how the condition changes. The goal is to learn patterns that could help future treatments or care plans.
Pittsburgh, PennsylvaniaAges Any age - NCT03564483Recruiting
Study for vulvar or anal skin cancer called EMPD
This study is for women with a specific rare skin cancer called extramammary Paget’s disease (EMPD) in the vulvar or perianal area. The goal is to better understand the condition and test an approach for people with primary or returning (recurrent) disease in those locations.
Rochester, MinnesotaAges 18 years+ - NCT06065852Recruiting
National registry for rare kidney diseases
This study creates a registry to collect health information from people with rare kidney diseases. It aims to improve understanding and future treatments by tracking patient experiences.
Bristol, South WestAges Any age - NCT07716488Recruiting
Screening for high cholesterol in children with chronic conditions
This study screens children and teens with certain chronic conditions (like heart defects or inflammatory bowel disease) for early signs of high cholesterol or other lipid problems. The goal is to find and manage these risks sooner.
JenaAges 6–18 - NCT07093346Recruiting
Pectin supplement for fatty liver disease
This study tests whether a pectin supplement (a fiber found in fruits) can reduce inflammation and improve liver and metabolic health in people with fatty liver disease (MASLD). You might be eligible if you have MASLD, a healthy weight range, and can avoid certain medications and foods.
Nottingham, United KingdomAges 18 years+ - NCT06573723Recruiting
Rare disease registry at Hospital Italiano
This study collects information from patients with certain rare diseases to better understand them. If you have one of these conditions and receive care at Hospital Italiano de Buenos Aires, you may be able to join.
Buenos Aires, Buenos AiresAges Any age - NCT06203106Recruiting
NYSCF Scientific Discovery Biobank
This study collects blood, saliva, or skin samples from people with certain neurological conditions and from healthy volunteers to help researchers better understand and find treatments for these diseases.
New York, New YorkAges 4 weeks+ - NCT06610201Recruiting
Study of a new treatment for Von Willebrand disease bleeding
This study is testing a new treatment for people with certain types of Von Willebrand disease (Type 1 or 2A) who have frequent bleeding problems. It aims to see if the treatment can help reduce these bleeding episodes.
Phoenix, ArizonaAges 16 years+ - NCT06235385Recruiting
European study on multiple and mixed valve disease
This study looks at people with multiple or mixed heart valve disease (moderate or severe) using echocardiography. It aims to learn more about how these conditions affect patients and help guide future care.
Paris, Île-de-France RegionAges 18 years+ - NCT07743021Recruiting
Blood sample study for better health screening
This study collects blood samples and health information over time to improve early detection of diseases. It may help researchers find ways to prevent serious conditions.

Risk scores after abdominal surgery for people with health conditions
This study looks at how other health problems affect the chance of postoperative complications after abdominal surgery. It aims to help doctors better predict risk and decide on the safest care for you.
ArkhangelskAges 18 years+ - NCT07217535Recruiting
Studying the genetics of kidney disease
This study collects DNA and health information from people in the U.S. to better understand how genes may affect kidney disease. Your participation could help researchers find new ways to prevent or treat kidney problems.

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.
