Recruiting studies
- NCT00106925Recruiting
Long-term follow-up for people after stem cell transplant
This study follows people who are at least 3 years out from their first stem cell transplant to learn how they are doing long term. It may help improve future transplant care by tracking outcomes over time.
Bethesda, MarylandAges 7–80 - NCT00001620Enrolling by invitation
NIH screening to see which blood studies fit you
This study is a general screening step at the NIH Clinical Center to check whether you might qualify for other NHLBI research protocols. It helps match you (or a donor/healthy volunteer) to the right study and confirms you can consent to participate.
Bethesda, MarylandAges 2–100 - NCT00001987Recruiting
Understanding genetics of insulin resistance and diabetes
This research study looks at the genes and immune system factors that cause severe insulin resistance—a condition where the body doesn't respond well to insulin. Researchers want to understand why some people develop this problem and study family members and healthy volunteers to learn more.
Bethesda, MarylandAges 6 months–120 years - NCT00404560Recruiting
Blood tests to study infection risk and immune problems
This study looks at how the immune system works in people who have—or might have—an increased risk of infections. It also enrolls their healthy blood relatives so researchers can compare immune features; results may help doctors understand who is at higher risk and why.
Bethesda, MarylandAges 1 month–100 years - NCT00081523Recruiting
Understanding How Sickle Cell Disease Develops Over Time
This research study follows people with sickle cell disease to learn how the condition affects their health over many years. By studying patients regularly, researchers hope to better understand the disease and improve care.
Washington D.C., District of ColumbiaAges 2–90 - NCT00767312Enrolling by invitation
Study how HIV multiplies during HIV drug treatment
This study looks at how HIV continues to multiply (or stays suppressed) while you are taking antiretroviral therapy, using blood samples. It may help researchers better understand what HIV is doing during treatment and why some people experience changes like viral rebound.
Bethesda, MarylandAges 18–99 - 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+ - NCT00001244Recruiting
Studying Immune System Disorders and Family Genetics
This research study examines how the immune system malfunctions in patients with common variable immunodeficiency (CVID)—a condition where the body doesn't make enough antibodies to fight infections. Researchers want to understand the genetics and immune patterns to help develop better treatments. Family members may also be asked to participate to help identify genetic causes.
Bethesda, MarylandAges 2–120 - NCT00029445Recruiting
Blood and Cell Collection Study for HIV Research
This research study collects blood cells from adults with HIV and their family members to understand why some people's immune systems control HIV better than others. Researchers will use your cells to study HIV immunity and develop better treatments.
Bethesda, MarylandAges 18–100 - NCT00001355Recruiting
Understanding immune system cell defects and family patterns
This research study investigates problems with immune system cells called phagocytes that help fight infections. Researchers will study patients with suspected immune defects and their blood relatives to better understand these conditions and develop better care.
Bethesda, MarylandAges 1 month–100 years - NCT00001316Recruiting
Study viral levels in blood and lymph node tissue with HIV
This study measures how much HIV is in your blood and lymph node tissue. If you qualify, you would also allow blood and other tests (including genetic and hepatitis screening), which may help researchers better understand how HIV affects the body.
Bethesda, MarylandAges 18–100 - NCT00428987Recruiting
Study of body and behavior traits in weight groups
This study looks at how physical traits and everyday behaviors differ among people who are overweight, obese, or in the normal-weight range. It may help researchers better understand risk factors related to weight and health.
Bethesda, MarylandAges 18–100 - NCT01145196Recruiting
Study drug eye damage and genes in Plaquenil users
This study looks at how Plaquenil (hydroxychloroquine) can harm the retina (the eye’s light-sensing layer) and whether genetics affect who gets affected. You may help by sharing medical details and providing an eye-related blood sample so researchers can compare gene patterns to eye findings.
Bethesda, MarylandAges 18–120 - NCT00339287Recruiting
Healthy adults donate blood to study bacteria-fighting cells
This study looks at how a person’s immune cells interact with bacterial germs. You’d be screened as healthy and may donate blood (and possibly tissue), with samples stored for future research.
Hamilton, MontanaAges 18–120 - NCT00001205Recruiting
Understanding neurocysticercosis outcomes in treated patients
This study follows patients who have been treated for neurocysticercosis—a brain infection caused by a parasite—to learn how they recover over time and what long-term effects they experience. By joining, you'll help doctors better understand this condition and improve care for future patients.
Bethesda, MarylandAges 3–99 - 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 - NCT00001352Recruiting
Understanding Why Some People Get Fungal Infections
This study looks at genetic reasons why some people are susceptible to a serious fungal infection called cryptococcosis. Researchers will collect blood samples and perform genetic testing to understand the immune system differences that make certain individuals more vulnerable to this infection.
Bethesda, MarylandAges 18–99

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,353 recruiting 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 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 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.
