Recruiting studies
- 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+ - 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 - 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 - NCT04307667Recruiting
Study brain immune activity in people with mild asthma
This trial studies how immune cells in the brain (called microglia) may be activated in asthma. You may be able to help researchers test whether a specific “immune pathway” differs in certain asthma patients using brain scans and breathing/allergy testing.
Madison, WisconsinAges 18–75 - NCT04380038RecruitingPhase 4
Viral infection study in well-controlled asthma adults
This study looks at how a viral infection affects people with well-controlled asthma. It tests whether specific asthma-related immune signals can predict who reacts more to a virus, which may help guide future asthma care.
Charlottesville, VirginiaAges 18–40 - NCT04442646Recruiting
Asthma education program for better self-management
This study looks at an “Asthma School,” an education and support program, to help adults manage their asthma day to day. It may help you learn practical ways to control symptoms and know what to do when asthma flares.
Tradate, LombardyAges 18–85 - NCT04565483RecruitingPhase 4
Test a blood-test signature to predict benralizumab benefit
This trial studies whether a specific “signature” from asthma tests can predict who will respond to benralizumab (a severe asthma biologic). If you qualify, the researchers will compare your test results to how well benralizumab controls your asthma and prevents flare-ups.
Aix-en-ProvenceAges 18–75 - NCT04639791Recruiting
Managing asthma in adults on GINA steps 4 to 5
This study looks at how well guideline-based asthma treatment works for adults with more severe asthma (GINA steps 4 and 5). It may help improve real-world care for people whose asthma needs stronger medications to stay controlled.
ShatinAges 18 years+ - NCT04763447RecruitingPhase 4
Short omalizumab treatment for severe allergic asthma
This trial tests whether stopping omalizumab for a short time (or using it differently) can be safe for adults with severe allergic asthma who are doing well. It may help some people avoid long-term injections, but only if asthma remains well controlled.
Paris, Île-de-France RegionAges 18 years+ - NCT05028153RecruitingPhase 2
Azithromycin for young children with asthma-like hospital symptoms
This trial tests whether the antibiotic azithromycin can help children in the hospital who are having asthma-like breathing symptoms. If you qualify, your child may get azithromycin as part of the study and will be monitored closely for side effects and breathing improvement.
Gentofte MunicipalityAges 1 year–5.9 years - NCT05140889Recruiting
AI helps predict asthma severity in children
This trial studies an AI (computer) model that uses CT scan images plus health and blood/clinical information to predict how severe asthma is in children. It may help doctors better understand your child’s asthma severity and tailor care.
PaviaAges 6–17 - NCT05192499Recruiting
Study gut-and-lung bacteria in very young children with asthma
This study looks at whether differences in the body’s bacteria (in the gut and/or airways) can help predict which toddlers with asthma may develop a more severe form. It may help doctors identify children at higher risk earlier so they can be monitored more closely.
Brest, FinistèreAges 1–3 - NCT05222529RecruitingPhase 2
Study medicine dosing in children with asthma using inhaler tests
This Phase 2 study checks how glycopyrronium bromide works in children with asthma, including its safety and how well inhaler dosing is tolerated. It also uses breathing tests and inhaler technique checks to confirm your child meets key asthma and lung function requirements.
RousseAges 6–11 - NCT05341726Recruiting
Test a program to improve asthma control in Black adults
This study tests an approach that combines education and support to help adults with uncontrolled asthma manage their symptoms better and use treatments correctly. It focuses on Black adults receiving care at specific community health clinics.
Beacon, New YorkAges 18 years+ - NCT05364632Recruiting
Exercise training to improve activity in people with asthma
This trial compares an aerobic exercise program with a behavioral program to help increase physical activity in people with asthma. It may help you build safer activity habits, especially if your asthma symptoms are not well controlled.
São Paulo, São PauloAges 18–65 - NCT05364957Recruiting
Gastric balloon plus asthma care for uncontrolled asthma and obesity
This study tests whether placing a soft “balloon” inside the stomach (intragastric balloon) can help people who have uncontrolled asthma and obesity. It also checks whether the balloon is safe and can improve asthma control when standard inhaler treatment is already in use.
Toulouse, OccitanieAges 18–65 - NCT05420766Recruiting
Sleep and immune balance study in children with asthma
This study looks at how getting a certain amount of sleep affects the body’s immune system balance in children with asthma. It may help researchers understand whether sleep habits could influence asthma-related health.
Providence, Rhode IslandAges 7–11 - NCT05445583Recruiting
Technology support program for young adults with uncontrolled asthma
This study tests whether a technology-based program can help improve asthma control in young African American adults who are not currently well controlled. It may help you track symptoms and use asthma tools more consistently between clinic visits.
Tallahassee, FloridaAges 18–30 - NCT05496582Recruiting
Study genes linked to asthma using a lab-based approach
This trial looks at how certain proteins (Transgelin-2, Metallothionein-2, and Ezrin) are associated with asthma. It may help researchers better understand asthma biology and potentially guide future treatments.
