Recruiting studies
- NCT04864886Recruiting
Study how immune-related conditions affect metabolism
This study collects blood and other samples to see how the immune system changes “metabolism” (how your body uses energy) in people with immune-related conditions. Your samples may also be stored for future research and could help researchers better understand immune health.
Bethesda, MarylandAges 18–75 - NCT04891237RecruitingPhase 3
Grass and olive allergy vaccine trial for teens to older adults
This Phase 3 trial tests whether an allergy treatment can reduce symptoms caused by grass and olive pollen. It also checks safety, especially for breathing and allergic reactions, in people with confirmed grass/olive allergy.
Tarancón, CuencaAges 12–65 - NCT04898283RecruitingPhase 3
Allergy shot study for grass and cypress pollen symptoms
This phase 3 trial tests a specific allergy treatment (an “immunotherapy” shot) for people whose symptoms are triggered by grass and cypress tree pollen. It aims to see if the treatment is safer and more effective at reducing allergy symptoms over time, especially for nose/eye symptoms and some people with asthma.
Valladolid, Castille and LeónAges 12–65 - NCT07536308RecruitingPhase 1

Bethesda, MarylandAges 18–99 - NCT05042830Recruiting
Tests how birch allergy in the nose affects allergy signals in blood
This study looks at people with a birch pollen allergy to see how exposure in the nose can change allergy-related blood signals. The results may help explain why symptoms can “boost” throughout the body after nasal allergen contact.
Vienna, State of ViennaAges 18–60 - NCT05201469RecruitingPhase 2
VIB4920 for lupus kidney inflammation not responding well enough
This Phase 2 study tests VIB4920 to treat active lupus nephritis, a type of kidney disease caused by lupus. It may help reduce kidney inflammation and improve kidney outcomes in people with active disease despite standard care.
La Jolla, CaliforniaAges 18 years+ - NCT05266222Recruiting
Collecting respiratory virus samples for a research library
This study collects samples from people who have or might have a cold/respiratory virus, then stores them for future research. It may help researchers better understand respiratory germs and develop better treatments.
Bethesda, MarylandAges 3 years+ - NCT05272241Recruiting
Asthma registry that helps researchers learn about asthma
This study enrolls people in specific cities to collect health information that helps researchers better understand asthma and how to recruit future studies. It may help by improving knowledge about asthma types and care in real-world settings.
Aurora, ColoradoAges Any age - NCT05323357Recruiting
Study using gut samples to understand germs and your immune system
This study collects gut tissue (biopsies) and blood to learn how gut germs (microbes) and the immune system interact. It may help researchers understand why gut infections or immune problems happen and improve future treatments.
BernAges 18–80 - NCT05331170RecruitingPhase 2
Re-training the nose to change how allergies behave
This Phase 2 study tests a “viral” treatment meant to reprogram the lining of your nose to reduce allergy-like immune responses. It is testing whether this approach is safe and can help people with cat allergy (with or without asthma) or compare against healthy people.
Galveston, TexasAges 18–60 - 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 - NCT05383742RecruitingPhase 2
Compare 6- vs 9-month treatment for tuberculous meningitis
This Phase 2 study tests whether a shorter, stronger 6-month set of medicines works as well as the usual 9-month regimen for tuberculous meningitis (TB infection in the covering of the brain/spinal cord). The goal is to improve outcomes while reducing treatment time and exposure.
Porto AlegreAges 15 years+ - NCT05394363Recruiting
Victoria children birth-cohort study with parent/guardian consent
This study follows children born in a specific 2-year window and their parents or guardians over time. It helps researchers understand how children and families change as they grow, which can guide future health supports in Victoria.
Parkville, VictoriaAges 1 day+ - NCT05395689RecruitingPhase 3
Dust mite allergy vaccine for ongoing runny nose and asthma
This Phase 3 study tests Beltavac®, a treatment aimed at dust mite allergies, to see if it can improve persistent nasal allergy symptoms and help people whose asthma is also affected. You may be a good match if you have confirmed dust mite sensitization and ongoing moderate-to-severe symptoms.
