- 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.

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 - NCT00001406Recruiting
Understanding eosinophil behavior in rare blood and tissue conditions
This research study examines how eosinophils (a type of white blood cell) behave and function when they become abnormally high in the blood or tissues. Researchers want to understand these conditions better to potentially improve treatment options.
Bethesda, MarylandAges 1–100 - NCT00032513Recruiting
Genetic study of chronic active Epstein-Barr virus disease
This research study looks for genetic factors that may explain why some people develop severe, long-lasting Epstein-Barr virus (EBV) infection. Researchers will study blood and tissue samples from patients with this rare condition, their healthy relatives, and unrelated volunteers to understand the disease better.
Bethesda, MarylandAges 1–120 - NCT02190266Recruiting
Study genetics and cause of hard-to-treat Valley fever
This study looks at why “Valley fever” is difficult to treat or has spread beyond the lungs, and how a person’s genetics may be involved. You may be asked for blood or other samples for genetic testing and for storing samples for future research.
Bethesda, MarylandAges 2–100 - NCT06959771RecruitingPhase 1/Phase 2
Gene therapy for CD40L deficiency (Hyper-IgM syndrome) - single patient study
This trial tests a new gene therapy that uses a person's own blood stem cells and T cells, which are corrected with a gene-editing tool called base editing. It is designed for people with a specific CD40L gene mutation who also have liver problems and portal hypertension. The goal is to see if this treatment can improve their immune system and liver health.
Bethesda, MarylandAges 37–120 - NCT00001467Recruiting
Study of genes in immune disorders
This research looks at how inherited (genetic) changes may affect the immune system in people with immune problems. It may help by improving understanding of these conditions and, in some cases, guiding faster care for a baby after birth.
Bethesda, MarylandAges 1 day–101 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 - NCT03835767RecruitingPhase 2
Predicting food allergy from blood IgE levels in eczema patients
This study looks for blood test patterns that may predict whether a child with eczema (atopic dermatitis) is likely to have a food allergy. If you join, you may do supervised oral food challenges with a placebo and the suspected foods to see what triggers symptoms.
Bethesda, MarylandAges 3–21 - NCT00246857Recruiting
Screening study for inherited immune system conditions
This study screens people who may have an inherited immune system condition (like problems with immune cell growth or death) and their blood relatives. The goal is to understand the condition better by collecting blood samples for testing.
Bethesda, MarylandAges 1 month–100 years - NCT03878121RecruitingPhase 1
Ad4-HIV vaccine study for healthy adults and partners
This Phase 1 study tests whether an experimental HIV vaccine (made from a harmless viral vector) is safe and helps the body build immune defenses. It includes healthy volunteers and, in some groups, their close partners, with careful screening and follow-up visits.
Bethesda, MarylandAges 18–65 - NCT00029445Recruiting
Blood and Cell Collection Study for HIV Research
