This study looks at how well the pancreas works (both hormone and digestive functions) and what happens to patients after pancreas removal surgery. It may help doctors better predict recovery and long-term health.
Taipei, TaiwanAges 20–75 - NCT01036581Recruiting
Brain MRI study to improve brain imaging for drug research
This study uses advanced MRI brain scans to better show how the brain responds to medicines (drug-related effects). You may also do extra safety screening and non-invasive brain stimulation for some parts of the research.
Baltimore, MarylandAges 18–80 - NCT00001406Recruiting
Understanding eosinophil behavior in rare blood and tissue conditions
This research study examines how eosinophils (a type of white blood cell) behave and function when they become abnormally high in the blood or tissues. Researchers want to understand these conditions better to potentially improve treatment options.
Bethesda, MarylandAges 1–100 - NCT01630421Recruiting
Study genes behind aplasia cutis congenita (ACC)
This study looks at the genes and body effects behind aplasia cutis congenita (ACC). It is mainly for people who have ACC, and it may include unaffected family members only if they are part of a research family group.
Farmington, ConnecticutAges Any age - NCT01630447Recruiting
Study of cherubism genes and how the condition works
This study looks at the genes in people with cherubism to understand how the condition develops. If you have cherubism—or are part of a family where cherubism is being studied—you may be invited to take part.
Farmington, ConnecticutAges Any age - NCT01630460Recruiting
Study of genetics in craniometaphyseal dysplasia (CMD)
This study looks at the genes and related body functions in people with craniometaphyseal dysplasia (CMD). It may help researchers understand the condition better, especially by comparing affected family members to those who are not affected.
Farmington, ConnecticutAges Any age - NCT00128973Recruiting
Study immune system problems in people with unusual infections
This study looks at how the immune system works in people who have abnormal immune function, often shown by unusual or repeated infections or long-lasting inflammation. It may involve tests using blood samples and storage of blood for future research.
Bethesda, MarylandAges Any age - NCT00051857Recruiting
MRI Study of Muscle and Bone Function
This research study uses MRI scans (a safe imaging tool) to understand how bones, muscles, and joints work. Researchers are looking for both people with muscle or bone injuries and healthy volunteers to compare how the body moves and functions.
Bethesda, MarylandAges 5–95 - NCT00230165Recruiting
Genetics and blood testing for inherited bleeding disorders
This study looks at genes and blood function in people with inherited (passed-down) problems with platelets, white blood cells, or blood clotting. It may help improve understanding of the cause of these conditions and how they work in the body.
New York, New YorkAges Any age - NCT00025935Recruiting
Brain Function Studies in Youth With Mood and Attention Disorders
This research study examines how the brains of children and teenagers with mood problems (like persistent irritability or depression) or attention difficulties work differently. Researchers use brain scans and tasks to understand these conditions better and track changes as young people grow up.
Bethesda, MarylandAges 7–60 - NCT01581424Recruiting
Study how kidney findings change in Fabry disease
This study looks at the natural course of Fabry disease in the kidneys and how different kidney test results relate to each other. It may help doctors better understand kidney progression and treatment outcomes, including for people who have or have not had enzyme replacement therapy.
Minneapolis, MinnesotaAges 1–75 - 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 - NCT01929356Recruiting
Breathing therapy test for primary ciliary dyskinesia
This study looks at how chest physiotherapy affects lung function in people with primary ciliary dyskinesia (a lifelong condition affecting mucus movement in the lungs). It may help care teams understand which breathing therapies work best and how your lungs respond.
LeuvenAges 6–50 - NCT01999374Recruiting

Common questions
- Are there clinical trials for functionality?
- Yes. Clin2 currently lists 2,566 recruiting functionality 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 functionality 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 functionality 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.
