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 - 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 - NCT00001539Recruiting
Lyme disease study's treatment and recovery health

Bethesda, MarylandAges 18–65 - 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 - NCT04052022Recruiting
Study of TB flare-ups in people without HIV
This study looks at why some people with tuberculosis (TB) get worse or develop new inflammation after they initially start improving on treatment—called a “paradoxical reaction.” It collects blood and tissue samples to better understand these flare-ups and guide future care.
Bethesda, MarylandAges 18–99 - NCT03937817Recruiting
Donate samples to study globin gene variants
This study collects common body samples to learn how different globin gene variants work and how they relate to health. Your samples may also be used later for new research, including genetic testing.
Bethesda, MarylandAges 18–70 - NCT06974877RecruitingPhase 1
PET/CT Imaging for Amyloid in CAPS on Anakinra
This trial uses a special PET/CT scan to see if a radioactive tracer can measure changes in amyloid buildup in people with CAPS who have developed a skin reaction to anakinra. It may help doctors understand how the disease is affecting your organs.
Bethesda, MarylandAges 18–120 - NCT04097561RecruitingPhase 1
Belimumab safety study for low CD4 counts and autoantibodies
This Phase 1 study tests how safe belimumab is for people with idiopathic CD4 lymphopenia (low protective white blood cells) and signs of autoantibodies. It aims to learn whether the treatment is tolerable and could be a future option for people with this immune condition.
Bethesda, MarylandAges 18–70 - 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 - NCT05026138Recruiting
Study of severe HPV disease and why it keeps coming back
This study follows people with severe or hard-to-treat HPV-related conditions (and some closely related partners/household contacts) to learn how the virus causes illness and how the immune system responds. It may help doctors better predict who will develop severe disease and guide future treatments.
Bethesda, MarylandAges 3–100 - NCT05398809RecruitingPhase 2
Ruxolitinib for hair regrowth in APECED-related alopecia areata
This Phase 2 study tests ruxolitinib to see if it safely helps regrow hair in people whose alopecia areata is linked to APECED (a rare immune condition). You may qualify if you have significant scalp hair loss for at least 6 months and haven’t had regrowth with other treatments.

String test for eosinophilic esophagitis in African patients
This study tests a new, less invasive way (the Esophageal String Test) to look for signs of eosinophilic esophagitis—an allergic condition that can make swallowing painful or difficult. It is for people of African descent who have trouble swallowing and are already having an endoscopy.
Bethesda, MarylandAges 18–65 - NCT05580458RecruitingPhase 1/Phase 2
Shingles vaccine study for adults with well-controlled HIV
This Phase 1/2 study tests how safe and how well a shingles (varicella zoster) vaccine works in adults living with HIV whose immune status is measured by CD4 count, plus a healthy comparison group. It may help researchers understand whether the vaccine can safely boost protection in people with HIV.
Bethesda, MarylandAges 18 years+ - NCT05463133RecruitingPhase 1/Phase 2
Stem cell transplant for chronic granulomatous disease
This study tests a stem cell transplant using a special conditioning regimen to treat chronic granulomatous disease (CGD), a condition that causes repeated infections and inflammation. The transplant aims to replace faulty immune cells with healthy ones from a donor, potentially reducing infections and improving quality of life.

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 - NCT06477653RecruitingPhase 2
Dupilumab for hypereosinophilic syndrome with ongoing symptoms
This trial tests if dupilumab, added to your current treatment, can help with remaining symptoms of hypereosinophilic syndrome (HES) like asthma, eczema, nasal polyps, or eosinophilic esophagitis. You may qualify if you're already on a biologic therapy that lowers eosinophils but still have bothersome symptoms.
Bethesda, MarylandAges 18–99 - 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 - NCT07111078RecruitingPhase 1
New Flu Vaccine (Stem) with or without Booster
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.
