Soquelitinib for ALPS-FAS-related swelling and low blood counts
This trial tests an investigational drug called soquelitinib to see if it can shrink enlarged lymph nodes and improve low blood cell counts in people with ALPS-FAS. It may offer a new treatment option for those who have active symptoms.
Bethesda, MarylandAges 16–120 - NCT06732414Recruiting
Long-term study of multiple allergic diseases
This study creates a biorepository to collect and store samples (blood, nasal fluid, skin swabs) from people with allergies, asthma, sinus disorders, or immune dysregulation. It aims to better understand these conditions over time, which may help develop better treatments.
Bethesda, MarylandAges 3–100 - NCT06607003RecruitingPhase 1
Testing a malaria infection in healthy adults
This study gives healthy adults who have never had malaria a controlled infection with the parasite that causes malaria, to see if it is safe and if mosquitoes can pick up the parasite from them. It may help develop new ways to prevent malaria.
Bethesda, MarylandAges 18–54 - NCT00001230Recruiting
Understanding How Your Body Responds to Filarial Infection
This study looks at how the body's immune system reacts to filarial infections—parasitic worms that affect millions worldwide. Researchers will observe your infection and response to treatment to better understand the disease and improve future care.
Bethesda, MarylandAges 3–100 - 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 - 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 - NCT00018044Recruiting
Study of mycobacterial infections and immune system
This study looks at how the body fights mycobacterial infections (a type of bacteria) and aims to find immune problems that make some people more prone to these infections. It may help us understand why some people get sick and could lead to better treatments.
Bethesda, MarylandAges Up to 100 years - NCT05652478RecruitingPhase 2
How HIV prevention drugs affect metabolism in healthy people
This study tests how certain HIV prevention drugs affect the body's metabolism (how it uses energy) in healthy people. It aims to understand side effects before these drugs are used more widely, which could help make future treatments safer.
Bethesda, MarylandAges 18–55 - NCT00557726Recruiting
Evaluation and care for inflammatory or infectious illnesses
This trial helps doctors evaluate possible infection or inflammation and decide on the best management plan. You may be able to receive specialized care at the NIH if the study team thinks your situation fits.
Bethesda, MarylandAges 3–100 - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
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+ - NCT00344188Recruiting
Study of Leishmania infections
This trial studies people with Leishmania infections (a parasitic disease often from sand fly bites). Researchers aim to better understand and treat the infection, and you may benefit from expert care.
Bethesda, MarylandAges 3–100 - 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 - 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 - NCT00867269Recruiting
Study of causes and progression of low CD4 blood cells
This study looks for what causes and how idiopathic low CD4 cells happen over time, using blood and tissue samples. It may help doctors learn why this occurs and how to better track people with it.
Bethesda, MarylandAges 18 years+ - 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+ - 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+ - NCT00091871Recruiting
Understanding familial high eosinophil disease in families
This study follows families with a genetic condition that causes high levels of white blood cells called eosinophils. Researchers want to understand how the disease develops and changes over time to help predict who may get worse and how to treat it better.

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.
