Washington D.C., District of ColumbiaAges 13–20 - NCT05656378Recruiting
Storing samples to study how the body interacts with microbes
This study creates a storage bank of biological samples like blood, stool, and tissue. Researchers will use these samples to learn how the body interacts with the natural microbes that live in and on us, which may help improve treatments for many diseases.
Bethesda, MarylandAges Any age - NCT00018044Recruiting
Understanding Immune Defects in Mycobacterial Infections
This research study aims to better understand why some people develop unusual bacterial infections (mycobacterial infections) that don't respond well to standard treatments. Researchers will examine your immune system and may study family members to identify genetic factors that increase infection risk.
Bethesda, MarylandAges Up to 100 years - NCT07027826Recruiting
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 - 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 - 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+ - NCT00067054Recruiting

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 - 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.

Adding lenacapavir to disrupt HIV reservoirs in suppressed people
This trial tests whether adding a new long-acting drug, lenacapavir, to your current HIV treatment can reduce the hidden HIV that remains in your body even when standard treatment keeps the virus undetectable. The goal is to see if this can lead to better control of HIV over time.
Bethesda, MarylandAges 18–75 - 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.

What taking part in a allergy study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
