Recruiting studies
- NCT00017914Recruiting
Understanding muscle inflammation: adult and juvenile myositis study
This research study helps doctors better understand myositis—a group of rare diseases that cause muscle inflammation and weakness. Researchers collect blood samples, medical history, and sometimes muscle biopsies to learn more about what causes these conditions and how to treat them better.
Atlanta, GeorgiaAges 2–100 - NCT01276470Recruiting
Study of environmental triggers in anti-synthetase syndrome
This study looks for environmental risk factors that may be linked to anti-synthetase syndrome, a type of inflammatory muscle disease. It compares people with the condition to carefully matched people without it, using questionnaires, blood samples, and lung imaging when needed.
Miami, FloridaAges 2–100 - NCT00001360Recruiting
Studying brain blood flow during thinking
This study looks at how blood flow in the brain changes while you are thinking. You will do tasks while having brain scans to help researchers understand normal brain activity.
Bethesda, MarylandAges 18–65 - NCT01143480Recruiting
Testing how the body responds to endotoxin
This study checks how your immune system (your body’s defense system) reacts to a controlled substance that triggers inflammation. It may help researchers understand why some people have stronger or weaker inflammatory responses.
Research Triangle Park, North CarolinaAges 18–100 - NCT00001595Recruiting
Study of pituitary tumors and related hormone gland disorders
This research study investigates tumors and disorders of the pituitary gland (a small gland that controls many body hormones) and related areas of the brain. You may qualify if you have a pituitary tumor or disorder, or if you have a family history of these conditions.
Bethesda, MarylandAges 2–70 - NCT00109174Recruiting
Brain chemical scan for healthy participants
This study uses a special MRI scan to measure natural brain chemicals. It helps researchers understand how the brain works in healthy people, which may inform future treatments.
Bethesda, MarylandAges 18–65 - NCT00102544Enrolling by invitation
Tracking Devices to Find Abnormalities During Medical Procedures
This study tests technology that uses imaging scans to help doctors locate and reach abnormalities during surgical or interventional procedures. The goal is to make these image-guided procedures more accurate and safer for patients.
Bethesda, MarylandAges 18–120 - NCT00001846Recruiting
Blood donation for medical research use
This study collects blood from healthy volunteers to be used in laboratory research. Your blood helps scientists study diseases and test new treatments in the lab.
Bethesda, MarylandAges 18–100 - NCT00018057RecruitingPhase 2
Brain study of pediatric anxiety disorders
This study looks at how the brain works in children and adults with anxiety disorders. It uses brain scans (fMRI) and other safe tests to understand anxiety better.
Bethesda, MarylandAges 8–65 - NCT01132885Recruiting
Brain scans in children with Williams syndrome
This study uses brain testing—often MRI scans—to learn how the brains of children with Williams syndrome are different from typical development. It may help researchers better describe brain patterns and improve future care for people with Williams syndrome.
Bethesda, MarylandAges 5–99 - NCT00344331Recruiting
Testing blood and MRI markers for Niemann-Pick type C
This study measures biochemical (blood/biologic) markers and may use clinical evaluation and MRI to better understand Niemann-Pick disease type C. It could help improve how the condition is tracked and understood over time.
Bethesda, MarylandAges 1 day–120 years - NCT00271622Recruiting
Screening test for child or adult brain and behavior patterns
This study uses a structured check-up to learn about how someone’s thinking, behavior, and development may differ from typical patterns. It involves an interview and possibly medical, nervous-system, and blood or urine tests to understand what kinds of issues might be present.
Bethesda, MarylandAges 1 month+ - NCT00397280Recruiting
Study of how immune cells react to different stimuli
This study measures how immune cells respond when exposed to test “stimuli.” It needs healthy, nonpregnant adults and screens for certain infections and recent illnesses or medicines to help ensure the results aren’t affected by outside factors.
Research Triangle Park, North CarolinaAges 18–65 - NCT00250159Recruiting
Natural history study for hormone-related excess androgen
This study follows people who may have too much “androgen” (a hormone) to learn what causes it and how it changes over time. You may be followed even if the exact cause is not yet known, and your results may help doctors better understand these conditions.
Washington D.C., District of ColumbiaAges 1 day–99 years - NCT00025935Recruiting
Brain function study in children with mood problems
This study looks at how the brain works and how mood disorders change over time in children and teens with severe irritability, anger, and temper outbursts. It includes brain scans and regular check-ins to understand the illness better.
Bethesda, MarylandAges 7–85 - NCT00004847RecruitingPhase 1
Understanding and Diagnosing Pheochromocytoma and Paraganglioma
This study helps doctors better understand and diagnose pheochromocytoma and paraganglioma—rare tumors that release stress hormones and cause high blood pressure and other symptoms. Researchers will study your medical history, blood and urine tests, imaging scans, and genetic information to improve how these conditions are found and understood.
Bethesda, MarylandAges 3–120 - NCT00001252Recruiting
Movement and Motion Study Database
This study builds a database of how people move and walk—both healthy volunteers and those with movement disorders. Researchers use this information to better understand neuromuscular conditions and improve treatment options.
Bethesda, MarylandAges 1 month–99 years - NCT00024635Recruiting
Understanding Mood and Anxiety Disorders Study
This research study evaluates people with mood disorders (like depression or bipolar disorder), anxiety disorders, or people without these conditions to better understand how these conditions develop and affect the brain. Researchers will ask questions and may do other assessments to learn more.
Bethesda, MarylandAges 3–99 - NCT00077909Recruiting
Study of Lung Proteins in Patients With Pneumonia
This research study examines proteins in fluid collected from your lungs during a breathing tube procedure (bronchoscopy) to better understand pneumonia. By studying these proteins, researchers hope to improve how doctors diagnose and treat lung infections.
Bethesda, MarylandAges 3–99 - 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 - NCT01266577Recruiting
MRI study measuring brain and muscle chemical levels
This study uses MRI techniques to measure natural chemical “metabolites” in the brain and muscle. You may be able to join if you’re generally healthy and can safely complete a long MRI scan.
Bethesda, MarylandAges 18–65

Common questions
- Are there clinical trials for health?
- Yes. Clin2 currently lists 5,397 recruiting health 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 health 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 health 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.
