Recruiting studies
- 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 - 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 - 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 - NCT00598351Recruiting
Study tracks changes in NF2 using repeated brain scans
This study follows people with neurofibromatosis type 2 (NF2) over time to learn how the condition changes, using repeat MRI scans. The information may help researchers understand disease patterns and improve future treatments.
Bethesda, MarylandAges 8–75 - 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 - NCT00034216Recruiting
Blood Collection Study for Cancer Patients and Healthy Volunteers
This study collects blood samples from people with cancer and healthy volunteers to help researchers understand cancer better. Your blood will be used for laboratory studies that may improve future cancer treatments.
Bethesda, MarylandAges 18 years+ - NCT00923221Recruiting
Donate blood for people with prostate cancer
This trial collects blood samples from adults with prostate cancer. It may help researchers learn more about the disease or how treatments work, without directly testing a new drug in the eligibility you provided.
Bethesda, MarylandAges 18 years+ - 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 - 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.
Bethesda, MarylandAges 18–120 - 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 - NCT00001539Recruiting
Lyme disease study's treatment and recovery health
This study looks at the health of people who have had Lyme disease, including those with ongoing symptoms after treatment, and those who have recovered or never had it. It aims to understand the disease and find better ways to manage it.
Bethesda, MarylandAges 13–99 - 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 - NCT00026884Recruiting
Blood and tissue sample collection for cancer research
This study collects blood and tissue samples from people with cancer or suspected cancer, or from their blood relatives. Researchers use these samples to better understand cancer and develop new treatments.
Bethesda, MarylandAges 2 years+ - NCT00895271Enrolling by invitation
Making lab cell lines from skin biopsies in immune disorders
This study creates special lab cell lines from skin (or nasal) samples from people with immune system disorders and certain family members. It’s meant to help researchers build tools to better study these conditions using patient cells.
Bethesda, MarylandAges 2–85 - NCT00001351Enrolling by invitation
Long-term study of immune system disorders
This study evaluates and follows patients with inflammatory conditions related to immune system problems. It aims to understand these disorders better and may offer opportunities to participate in other research.
Bethesda, MarylandAges 2 years+ - NCT00071045Enrolling by invitation
Tissue Collection From Cancer and Blood Disorder Patients
This study collects tissue samples from patients with cancer or blood disorders, and from their matching family members who might donate stem cells for transplant. The samples help researchers understand these diseases and develop better treatments.
Bethesda, MarylandAges 2–100 - 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+ - NCT00027326Enrolling by invitation
Blood and Urine Study During Radiation Therapy
This study collects blood and urine samples from patients receiving radiation therapy to understand how the body responds to treatment. It may help researchers improve radiation therapy in the future.
Bethesda, MarylandAges 18–120 - 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+ - NCT01143454Recruiting
Study unusual heart conditions and related genetic traits
This study looks at people with unusual or rare heart problems, or people with a family history of these issues. Doctors and researchers may collect and study your blood or tissue (and possibly store samples) to learn what causes the condition and how it may affect the heart.
Washington D.C., District of ColumbiaAges 1–100 - NCT00083512Recruiting
Blood and Urine Collection in Glioblastoma Radiation Therapy
This study collects blood and urine samples from patients receiving radiation treatment for glioblastoma (a serious brain tumor) to help researchers understand how the body responds to radiation therapy. Participating is straightforward—you provide samples during your regular treatment.
Bethesda, MarylandAges 18–120 - NCT00001778Recruiting
Understanding HTLV Infection and HAM/TSP Disease
This research study evaluates people with HTLV infection, a virus that can cause a nerve disorder called HAM/TSP. Researchers want to better understand who gets this condition and why, which may help develop future treatments.

Common questions
- Are there clinical trials for patient?
- Yes. Clin2 currently lists 14,158 recruiting patient 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 patient 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 patient 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.
