This trial tests a new type of flu vaccine that targets a part of the virus that doesn't change much (the stem). It is given with or without a special booster, and researchers want to see if it provides broader protection against different flu strains.
Bethesda, MarylandAges 18–50 - NCT06851767Enrolling by invitationPhase 1/Phase 2
Gene therapy for X-linked severe combined immunodeficiency
This study tests a gene therapy to treat X-linked severe combined immunodeficiency (X-SCID) without a stem cell transplant from a matched sibling. It aims to improve immune function and reduce infections using your own stem cells modified to carry the correct gene.
Bethesda, MarylandAges 3–99 - NCT05600920RecruitingPhase 1/Phase 2
Long-acting IL-7 drug trial for low CD4 immune cells
This Phase 1/2 study tests a long-acting IL-7 medicine to raise low CD4 immune cells in people with idiopathic CD4 lymphopenia. Because this is a dose-escalation study, the goal is to check safety and see if the treatment affects immune cell levels.
Bethesda, MarylandAges 18–75 - NCT07416201Recruiting
Study of Immune System Aging in Down Syndrome
This study is looking at how the immune system changes over time in people with Down syndrome, and how it may be affected by removal of the thymus gland. The goal is to understand why people with Down syndrome may age faster or have different immune health.
Bethesda, MarylandAges 1–120 - NCT05266222Recruiting

Bethesda, MarylandAges 3 years+ - NCT07113743Enrolling by invitationPhase 1/Phase 2
Gene therapy for x-linked chronic granulomatous disease
This trial tests a new gene therapy for X-linked chronic granulomatous disease (CGD), a condition where the immune system cannot fight certain infections. The treatment uses your own blood stem cells, which are modified in the lab to help your body produce working immune cells.
Bethesda, MarylandAges 3–60 - NCT01306084Recruiting
Study of viral infections in healthy and immune-compromised people
This trial studies how viruses affect the body, and how the immune system responds, in both healthy people and people with weakened immunity. It may include people who currently have a suspected or recent viral infection, close contacts, people around the time of a viral vaccine, and healthy adults used for comparison.
Bethesda, MarylandAges 6 months–120 years - NCT06479837Recruiting
Study using tonsil tissue to understand infections
This study uses tonsil tissue that is removed during a routine tonsillectomy to grow tiny 'organoids' in the lab. Researchers will study how germs interact with human cells, which could lead to better treatments for infections.
Bethesda, MarylandAges 2–120 - NCT03895645Enrolling by invitation
Research study using stored human samples
This study uses stored blood or other human samples that were saved from earlier medical research or care. It helps researchers answer new questions without needing you to give a new sample right now.
Bethesda, MarylandAges 18–116 - NCT02015013RecruitingPhase 2
Blood cell collection study for immune system disorders
This study collects blood-forming cells from people with low CD4 counts and healthy volunteers to learn how the immune system works. It may help researchers better understand and treat conditions like idiopathic CD4 lymphocytopenia.
Bethesda, MarylandAges 18–65 - NCT00044122Recruiting
Study of mast cell growth in people with mastocytosis
This study looks at what causes mast cells to grow too much in people with mastocytosis. It may help researchers find better ways to diagnose or treat this condition. You can take part in person or by telehealth.
Bethesda, MarylandAges 1 day–80 years - NCT02511002Enrolling by invitation
Long-term follow-up after an influenza challenge study
This study keeps track of how your body’s immune responses change over time after an influenza exposure. Researchers may use stored blood samples to study specific antibody levels, which could help improve future flu vaccines or treatments.
Bethesda, MarylandAges 18–120 - NCT01386437Recruiting
Study immune problems and fungal infections
This study looks at how immune system problems relate to fungal infections, using medical records and lab tests on blood and tissue. It may help researchers understand the cause of these infections—especially for people with inherited immune conditions—and improve future care.
Bethesda, MarylandAges 1 day–99 years - NCT07215871Enrolling by invitationPhase 1
Second H10N7 flu challenge for prior participants
This study tests whether people who have already been exposed to a lab-made H10N7 flu virus can be safely exposed again. It checks how their immune system responds and how long they shed the virus, in a controlled, isolated setting.
Bethesda, MarylandAges 18–55 - NCT00090662Recruiting
Healthy volunteer sample collection for research
This study collects blood, urine, stool, and other samples from healthy people to help researchers learn more about diseases and develop better treatments. If you join, you might donate samples like blood or, in some cases, bone marrow or skin, depending on your health and the study's needs.
Bethesda, MarylandAges 18–85 - NCT00006150Recruiting
Understanding Hyper-IgE Syndrome: Natural History and Genetics
This study follows people with or suspected Hyper-IgE syndrome (a rare immune disorder causing repeated infections and skin problems) to understand how the condition develops, how best to manage it, and which genes are involved. Researchers also welcome healthy relatives of patients to help identify genetic patterns.
Bethesda, MarylandAges 1 month–120 years - NCT06863142RecruitingPhase 1
Testing a new flu vaccine with or without adjuvant
This study tests a new investigational flu vaccine (FluMos-v2) with or without an adjuvant (ALFQ) to see how safe, tolerable, and effective it is. It may help protect against multiple flu strains.
Bethesda, MarylandAges 18–50 - NCT03610802Recruiting
Send blood samples to study genetic and immune differences
This study collects blood (and sometimes related samples) to learn how genes and the immune system work in people with primary immunodeficiency (PID) or in family members who may not have it. The goal is to improve understanding of rare immune conditions and help guide future care.
Bethesda, MarylandAges 1 day–99 years - NCT07706686RecruitingPhase 1
Dengue challenge study in people with prior infection
This study tests how the body responds to a mild, lab-made dengue virus in people who have had dengue before. It looks at how the immune system reacts to a second infection, which may help improve future vaccines and treatments.
Bethesda, MarylandAges 18–50 - NCT06908083Enrolling by invitationPhase 1
Stopping HIV treatment with antibody therapy
This trial tests whether a combination of powerful antibodies (bNAbs) can help control HIV after stopping standard HIV treatment. Participants will pause their daily HIV medications while receiving these antibodies, and doctors will closely monitor their immune system and virus levels. It's for people who are already well-controlled on HIV treatment and have participated in a specific earlier study.
Bethesda, MarylandAges 18–70 - NCT07262983RecruitingPhase 1
Baricitinib for Job syndrome with lupus or eczema
This study tests if baricitinib, a pill that changes how your immune system works, is safe and tolerable for people with Job syndrome who also have lupus-like disease or severe eczema. It might offer a new treatment option for these skin and immune problems.
Bethesda, MarylandAges 12–120 - NCT05333471RecruitingPhase 1/Phase 2
Fecal transplant for chronic bowel inflammation in CGD
This study tests whether transplanting stool microbiome (fecal microbiota transplant) can improve chronic colitis in people with chronic granulomatous disease (CGD). It aims to reduce bowel inflammation and symptoms by changing gut bacteria.
Bethesda, MarylandAges 10–60 - NCT06908096RecruitingPhase 1
EBV nanoparticle vaccine study for healthy adults
This study tests two experimental vaccines against Epstein-Barr virus (EBV), the germ that causes mono. You may be able to join if you are a healthy adult aged 18–29 and haven't had an EBV vaccine before. The trial will check if the vaccines are safe and trigger an immune response.
Bethesda, MarylandAges 18–29 - NCT06253507Enrolling by invitationPhase 1/Phase 2
Gene Therapy for Chronic Granulomatous Disease
This study tests a new gene therapy for people with a rare immune disorder called chronic granulomatous disease (CGD), which causes repeated infections. The treatment uses a modified virus to deliver a healthy gene to your blood stem cells, potentially helping your immune system fight off bacteria and fungi. The goal is to reduce the risk of severe infections and improve overall health.
