Liège, LiegeAges 18–65 - NCT04307667Recruiting
Brain cell activity in mild asthma and allergies
This study looks at brain inflammation in people with mild asthma who are also allergic to common triggers like cats, dust mites, or ragweed. It uses MRI scans to see if a certain brain cell activity is different, which may help us understand asthma better and lead to new treatments.
Madison, WisconsinAges 18–75 - NCT04160910RecruitingPhase 2
Studying 5HTP to manage asthma symptoms in kids
This Phase 2 study tests whether 5HTP can help regulate asthma in children and teens who have mild to moderate asthma linked to allergies. It may be an option if your symptoms are allergy-related and you can follow study visits and questionnaires.
Indianapolis, IndianaAges 8–18 - NCT04157361Recruiting
Non-invasive lung testing in asthma and cystic fibrosis
This trial studies how well a non-invasive lung test can show lung involvement in people with asthma (especially IgE-related asthma) and people with cystic fibrosis. You might benefit by getting extra lung assessments without invasive procedures.
OlomoucAges Any age - NCT04045587Recruiting
Registry for severe asthma in adults in Canada
This is a research registry that collects health information from adults with severe asthma to better understand how the condition behaves and how treatments are used. You may be able to take part if your asthma is considered severe and is not well controlled.
Edmonton, AlbertaAges 18 years+ - NCT03889743RecruitingPhase 4
Steroid treatment to help prevent asthma after a first wheezing illness
This trial studies whether an early steroid treatment can lower the chance that children will go on to develop asthma after their first severe “wheezing” episode caused by a rhinovirus (a common cold virus). If you qualify, the goal is to prevent future asthma rather than just treat the current episode.
TurkuAges 3 months–1.9 years - NCT03983603Recruiting
Plant stanols and asthma symptoms prevention
This trial tests whether eating plant stanols (a natural substance found in some foods) can help prevent asthma symptoms in people with stable allergic asthma. You would need to take a daily chew and avoid certain cholesterol-lowering products during the study.
Maastricht, LimburgAges 18–70 - NCT02327897Recruiting
Study of asthma symptoms and air exposures over time
This study follows people with moderate-to-severe asthma and repeatedly checks how their lungs and symptoms relate to environmental exposures over time. It may help researchers better understand what triggers asthma and how exposures affect asthma control.
Research Triangle Park, North CarolinaAges 18–60 - NCT02351141Recruiting
MRI study of lung function in people with asthma
This study uses MRI pictures to learn how asthma affects breathing and lung function. If you have asthma and can do breathing tests, you may be asked to take part to help researchers understand asthma better.
London, OntarioAges 18–60 - NCT02624362Enrolling by invitation
Testing how smells affect asthma symptoms
This trial studies whether different odors change your asthma symptoms. It may help researchers understand triggers and symptom patterns to improve asthma care.
LeuvenAges 18–65 - NCT05147688RecruitingPhase 1
