Test whether antibodies relate to food reaction symptoms
This study looks at adults who have symptoms they believe are caused by reactions to foods. Researchers will test immune blood markers (antibodies) to better understand what may be driving these symptoms and whether that information could help people in the future.
MadridAges 18–80 - NCT05528900Recruiting
Study of children with acute food-triggered gut reactions
This study follows children (from birth to age 17) who have been diagnosed with acute food protein–induced enterocolitis syndrome (FPIES). Doctors want to better understand this condition after a suspected reaction to food, using either symptom-based diagnosis or a supervised food challenge when needed.
AngersAges Up to 17 years - NCT05449756Recruiting
Long-term follow-up for children from the TEMPO study
This study checks on children who already took part in the TEMPO study during their first year of life. It helps researchers understand how things turned out over time and uses your child’s earlier study information.
BeekAges 3–10 - NCT06248957Recruiting
Immune system study for people with hard-to-treat immune diseases
This study aims to understand the immune system in people who have immune problems or whose immune-related diseases are not helped by standard treatments. It may lead to better ways to diagnose and treat these conditions.
StockholmAges Any age - NCT06261554Recruiting
Low-dose sesame oral immunotherapy for children
This study tests if a very low daily dose of sesame protein (given as a powder under the tongue) can help children with sesame allergy become less sensitive to sesame. The goal is to reduce the risk of severe allergic reactions from accidental exposure.
Warsaw, Masovian VoivodeshipAges 3–17 - NCT06446232Recruiting
Flu vaccine effectiveness in young children
This trial studies how well the flu vaccine works in young children in Taiwan. To join, your child must have a positive flu test and a known vaccination record.
TaipeiAges 6 months–18 years - NCT06390878Recruiting
Study on natural kindergarten yards
This study looks at how bringing nature back into kindergarten yards might affect children's health. It involves children who attend kindergarten and have not used antibiotics recently.
Helsinki, UusimaaAges 1–5 - NCT07778459Recruiting
Liver transplant study for people with HIV
This study tests whether it's safe and effective for people with HIV to receive a liver transplant from a donor who also has HIV. It aims to expand access to transplants for people with HIV.
Baltimore, MarylandAges 18 years+ - NCT04014413Recruiting
Fecal transplant for gut and immune-related conditions
This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
Hong Kong, ShatinAges Any age - NCT05420935Recruiting
Study of antibodies after operating-room allergic reactions
This study looks at different kinds of allergy-related antibodies in people who had an allergic reaction during surgery. The goal is to better understand what immune signals are involved so future allergy prevention and care can improve.
Paris, ParisAges 18–70 - NCT07757802RecruitingPhase 1
HIV vaccine nanoparticle and mRNA booster for healthy adults
This study tests a new HIV vaccine that uses tiny particles (nanoparticles) and an mRNA booster — similar to some COVID vaccines. The goal is to see if it is safe and helps your body fight HIV. It's for healthy adults who do not have HIV.
San Francisco, CaliforniaAges 18–55 - NCT07732855Recruiting
Treating eye surface inflammation
This study tests a treatment for inflammation on the eye's surface, specifically keratitis (cornea inflammation), to see if it can help calm the redness, pain, or irritation.
Budapest, Pest CountyAges 4–60 - 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 - NCT07701954RecruitingPhase 1
Testing a new drug for people with allergies and high IgE
This early-phase trial tests a new medication, LCA-0061, in healthy people with high IgE levels (a sign of allergies). Part B specifically includes those with a peanut allergy. The study aims to see how safe the drug is and how the body processes it.
Mississauga, OntarioAges 18–55 - NCT07675811RecruitingPhase 3
Study of a new treatment for cat allergy related eye symptoms
This trial tests an injectable treatment that may help manage eye allergy symptoms caused by cat allergies. It aims to see if the treatment is safe and effective for adults and children, and includes a controlled cat exposure challenge.
Andover, MassachusettsAges 8 years+ - NCT05820802Recruiting
Studying immune cells in children during surgery
This study looks closely at immune cells in children while they are having surgery under general anesthesia using a specific muscle-relaxing medicine (rocuronium). It may help researchers understand how immune systems respond around the time of surgery and anesthesia.
