Clinical trials
Asthma clinical trials
A condition where the airways narrow and swell, making breathing difficult. We’re tracking 390 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT04331353Recruiting
Asthma trial to reduce cockroach exposure at home
This study looks at whether reducing cockroaches in a child’s home can improve asthma control and reduce asthma flare-ups. It enrolls children who have ongoing (uncontrolled) asthma and will spend most nights in the study home.
New Orleans, LouisianaAges 5–17 - NCT04334031Recruiting
Hospital follow-up study for immune-related disease
This is a study that follows people with an immune-related illness at Lille University Hospital to better understand their care needs over time. By collecting information regularly, the study may help improve how future patients are monitored and treated.
LilleAges 18 years+ - NCT04435990RecruitingPhase 3
Allergy shots for dust mites in teens and adults
This Phase 3 study tests whether dust-mite allergy treatment (likely allergy shots) can reduce allergy symptoms and improve safety. It focuses on people whose nose/eye allergy is triggered by house dust mites and who may also have controlled asthma.
Santiago de Compostela, A CoruñaAges 12–65 - NCT04538937Recruiting
Study of high eosinophils causing lung/airway damage
This registry study looks at adults with high eosinophils (a type of immune cell) that are believed to be causing damage in the airways or lungs. It aims to better identify these eosinophils and understand what is going on so future treatments can improve.
InnsbruckAges 18 years+ - NCT04578171Recruiting
Mepolizumab for severe asthma flare-ups after treatment
This trial studies whether mepolizumab can reduce ongoing or returning asthma flare-ups in people with severe asthma. If you have severe asthma that still keeps flaring, this may help by targeting a specific inflammation pathway involved in some asthma cases.
Québec, QuebecAges 18–90 - NCT04624490RecruitingPhase 1
Lung function MRI using a special gas in volunteers
This Phase 1 study tests a lung scan that uses a special gas and MRI to measure how well your lungs work. It includes healthy volunteers and people with lung disease to see how well the scan works and how safe it is.
Kansas City, KansasAges 3 years+ - 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 - NCT04919265Recruiting
Mother and baby health study from early pregnancy
This study follows pregnant people and their babies from the first few months of pregnancy through at least one year after birth. It aims to learn how health and development turn out, especially for mothers who can keep coming to the same clinic for follow-up.
Kajang, SelangorAges 18–45 - NCT05009758Recruiting
Asthma and nasal polyps study to match immune patterns
This study looks at different “immune inflammation patterns” in people with asthma and/or nasal polyps. It may help researchers better tailor future treatments by figuring out which patterns go with which symptoms.
ViennaAges 18–99 - NCT05012033Recruiting
Study how high-dose steroids move through the body
This study measures blood levels of high-dose steroid medicines (prednisolone or related steroids) to understand how the body processes them in different real-life situations. It may help improve how steroids are dosed and monitored for people needing short-term or longer-term anti-inflammatory treatment.
LondonAges 18–75 - NCT05042219Recruiting
How lung disease treatment may affect heart function
This study looks at how common long-term lung conditions and their treatments may change heart function. It uses heart imaging (an MRI) to see what’s happening, which could help doctors better monitor heart risks in people with lung disease.
AachenAges 18–99 - NCT05147688RecruitingPhase 1
Safety study of donor stem cell treatment for lung disease
This early study tests whether donor stem cells made from umbilical cord tissue are safe in people with lung diseases. If you qualify, you may be offered the study treatment while the team closely checks for side effects and safety.
St John'sAges Any age - NCT05217810Recruiting
24-week real-world study of Atectura for asthma
This study follows people with asthma who are starting or using Atectura inhalation capsules to see how they do in everyday practice over 24 weeks. It may help your care team learn whether Atectura works well and safely outside a tightly controlled setting.
Daegu, Dalseo guAges 12–100 - 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 - NCT05332067RecruitingPhase 2
Omalizumab to prevent future asthma flare-ups before they start
This trial studies whether starting omalizumab before asthma flare-ups begin can reduce how often children get worsening asthma that needs strong steroid medicine. It is for children with persistent asthma who have signs of allergic/asthma triggers and recent flare-up history.
Washington D.C., District of ColumbiaAges 6–17 - NCT05336890Recruiting
Using past oxygen data to predict risks after premature birth
This study builds a personalized computer model that uses earlier breathing/oxygen information from preterm infants to predict possible health or development outcomes by preschool age. It may help families and doctors better estimate risks and plan support, using information already collected in a previous study.
Chicago, IllinoisAges 7 months–6.9 years - NCT05448066Recruiting
Tests allergen testing to choose allergy shots
This study checks how well a newer, detailed allergy test (using specific allergen components) can guide whether you should get allergy immunotherapy (allergy shots) for things like dust mites or grass pollen. It may help patients get the right treatment plan by improving how doctors confirm what allergens are driving symptoms.
PortoAges 5 years+ - NCT05734261Recruiting
Lung function test in children using metacholine
This trial studies how well a special breathing test (forced oscillations) works during a methacholine challenge in children. It may help doctors better measure breathing sensitivity and guide treatment decisions.
MontpellierAges 6–16 - NCT05989698Recruiting

Common questions
- Are there clinical trials for asthma?
- Yes. Clin2 currently lists 390 recruiting asthma studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a asthma trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a asthma trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
