Drug-coated balloon treatment registry for narrowed blood vessels
This study records outcomes for people who get a drug-coated balloon used to treat a narrowed blood vessel after a first balloon treatment. It may help doctors understand how well this approach works in everyday care and for different patient needs.
Bucheon-siAges 20 years+ - 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 - NCT01311258Recruiting
Tracking leftover cancer cells in AML or high-risk MDS
This study checks for “minimal residual disease,” meaning tiny numbers of leukemia cells that can remain after treatment. Results may help doctors better monitor your response and risk of relapse in AML or high-risk MDS.
Rochester, New YorkAges 18 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 - NCT01209000Recruiting
Study for children with new kidney protein loss
This study is for children (and some newly diagnosed patients) who have nephrotic syndrome—kidneys leaking a lot of protein. It aims to better understand the kidney condition (sometimes using biopsy) and support future care decisions.
Los Angeles, CaliforniaAges Up to 80 years - 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 - NCT00001350Recruiting
Understanding Autoimmune Lymphoproliferative Syndrome
This research study helps doctors understand ALPS, a rare immune disorder that causes swollen lymph nodes and spleen. Participating means providing blood samples and health information so researchers can learn how the condition develops and how to better care for patients.
Bethesda, MarylandAges Up to 99 years - 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 - NCT00001645Recruiting
Evaluation and treatment of parasitic infections
This study evaluates and treats patients who may have a parasitic infection (an infection caused by parasites—tiny organisms that live in or on the body). Researchers will monitor your condition and provide care to help you get better.
Bethesda, MarylandAges 3 years+ - NCT02060695Recruiting
Study links Parkinson symptom ups and downs over time
This study looks at how changes in movement symptoms and non-movement symptoms happen together in people with early Parkinson disease. It may help doctors better understand what triggers symptom “ups and downs” and how to time treatment or monitoring.
SeoulAges Any age - 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 - NCT01222741Recruiting
Study of people with higher risk of fungal infections
This study looks at immune system differences that can make some people get unusual or frequent fungal (fungus) infections. It may help researchers better understand these conditions, and you may be asked to store blood for future research.
Bethesda, MarylandAges 18–85 - NCT00789009Recruiting
Monitoring people with known or suspected HIV infection
This study tests how well researchers can track HIV-related health and immune changes over time by collecting blood and other samples. It may help you and your care team by creating detailed monitoring, even if your HIV diagnosis is new or still being evaluated.
Bethesda, MarylandAges 18 years+ - NCT01905826Recruiting
Study of GATA2 deficiency causes and health outcomes
This natural history study looks at how GATA2 deficiency (a genetic condition) affects health over time. It may help doctors better understand complications and plan future care, and it includes genetic testing and stored samples.
Bethesda, MarylandAges 2–100 - NCT00243776Recruiting
Study of heart tissue changes during certain heart surgeries
This study collects and analyzes small samples of heart tissue during specific heart operations in babies or children. The goal is to better understand how the heart develops after birth, which could improve future care.
Atlanta, GeorgiaAges Up to 20 years - NCT01011712Recruiting
Study immune causes of severe viral infections
This study looks at why some people have severe or unusual viral infections, even when they do not have a known immune problem. It collects blood and tissue samples to better understand possible inherited immune issues and may help future diagnosis and treatment.
Bethesda, MarylandAges 2–100 - 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.

How Genes Affect Lung Disease Development
This research study examines how genetic factors contribute to various lung diseases, including alpha-1 antitrypsin deficiency, cystic fibrosis, and chronic obstructive pulmonary disease. Researchers want to understand why some people develop lung disease and how genetics plays a role, which may help improve treatment in the future.

Long-term ibrutinib follow-up with or without nivolumab
This study looks at how safe and effective ibrutinib is over the long term, either alone or together with nivolumab. You may join if you are already in an earlier ibrutinib study and your care team feels staying on ibrutinib is worth the risk.
Duarte, CaliforniaAges 18 years+ - NCT00026650Recruiting
Understanding Long-Term Effects After Radiation Therapy
This study follows patients who have received radiation therapy to learn about long-term health effects and how the disease progresses over time. By tracking your health over the years, researchers hope to better understand and help future patients manage side effects.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,506 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.
