Clinical trials
Asthma clinical trials
A condition where the airways narrow and swell, making breathing difficult. We’re tracking 385 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT00576069Recruiting
Study airflow limits in moderate asthma
This trial looks at why airflow is limited in people with moderate-to-severe persistent asthma who are already on stable treatment. It may help researchers better understand what drives breathing trouble and how to target it.
Lakewood, CaliforniaAges 10–95 - NCT06126692Recruiting
Asthma study comparing different biologic treatments
This study looks at how well different biologic treatments work for people with severe or mild-to-moderate asthma, and compares them to healthy volunteers. It aims to find which treatments work best for different asthma types.
CopenhagenAges Any age - NCT05761028RecruitingPhase 2/Phase 3
CM310 for moderate to severe asthma despite current inhalers
This study tests CM310 to see if it can improve asthma in people with moderate to severe asthma who are still having uncontrolled symptoms and severe flare-ups despite regular inhaler treatment. You may be eligible if your lung function and asthma control tests fit the study limits and you’ve had a recent severe exacerbation.
Beijing, BeijinAges 12–75 - NCT07869043RecruitingPhase 3
Study of tilrekimig for people with severe asthma
This study tests an investigational medicine called tilrekimig for people with severe asthma that is not well controlled. The goal is to see if it can reduce asthma attacks and improve breathing.
Pittsburgh, PennsylvaniaAges 12–80 - NCT06230458Recruiting
FeNO breath test to help diagnose asthma
This trial is testing whether a simple breath test called FeNO can help doctors diagnose asthma more accurately. It's for people who have symptoms that might be asthma, but haven't been diagnosed yet.
Rotterdam, South HollandAges 18 years+ - NCT05708300Recruiting
Testing how mepolizumab works for people with nasal polyps
This study looks at blood and other measures (biomarkers) to understand how well mepolizumab helps people with nasal polyps, with or without asthma. It aims to find response clues that could help personalize treatment in the future.
Thessaloniki, ExochiAges 18 years+ - 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 - 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.
Changsha, HunanAges 14–75 - NCT07851623RecruitingPhase 1
Inhaled study drug for healthy adults and adults with asthma
This early-phase study tests an inhaled medication (CHF10136) to see if it's safe and how the body handles it. It includes both healthy adults and people with asthma, and participants will be monitored closely throughout.
LeedsAges 18–65 - NCT06535087Recruiting
How airway allergies affect children and parents' quality of life
This study looks at how airway allergies (like asthma and hay fever) affect the daily life of children and their parents. By filling out a questionnaire, you can help researchers understand these challenges and find better ways to support families.
Shanghai, Shanghai MunicipalityAges 5–16 - NCT07788534Recruiting
FeNO monitoring for children with asthma
This study compares asthma control in children who use a breathing test called FeNO to guide treatment versus a similar group that doesn't. It aims to see if FeNO monitoring helps improve asthma control.
Jeddah, Mecca RegionAges 6–14 - NCT06552013Recruiting
Asthma study for kids in Georgetown and South Park
This study tests whether reducing air pollution can help control asthma in children living in the Duwamish Valley. Kids with poorly controlled asthma who live in specified Seattle neighborhoods may benefit from cleaner air.
Seattle, WashingtonAges 6–17 - NCT06385236RecruitingPhase 4
Asthma genetics study to find better treatments
This study looks at how your genes affect your asthma medications. It tests if knowing your DNA can help predict which treatment works best for you and why.
Scottsdale, ArizonaAges 18–75 - NCT07772921RecruitingPhase 3
New study medicine for severe asthma
This study tests an investigational medicine called tilrekimig for people with severe asthma that isn't well controlled. It aims to reduce asthma attacks and improve breathing.
Bakersfield, CaliforniaAges 12–80 - NCT07768891RecruitingPhase 3
Asthma treatment with combination inhaler
This study tests a new combination inhaler for people with asthma. It may help control symptoms and improve breathing. Participants will either get the study inhaler or a standard treatment, and their asthma will be monitored closely.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT02496468Recruiting
Study for children with wheezing or asthma symptoms
This study follows children with wheezing (in younger kids) or doctor-diagnosed asthma (in older kids). It aims to better understand asthma and related breathing problems and how they develop over time.
CologneAges 6 months–18 years - 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 - NCT07746921Recruiting
Smart inhaler and remote asthma care for teens with intellectual disabilities
This study tests a smart inhaler and a phone app to help teenagers with mild-to-moderate intellectual or developmental disabilities manage their asthma at home. It aims to see if this technology improves asthma control and makes it easier for families to track medication use.
Los Angeles, CaliforniaAges 10–17 - NCT07735494Recruiting
Physical activity study for people with severe asthma starting tezepelumab
This study tests whether a physical activity program can help people with severe asthma achieve better control and reduce flare-ups when added to a new treatment called tezepelumab.
LeedsAges 18–70 - NCT07732023RecruitingPhase 1
Study of a new asthma medication compared to placebo
This study tests an investigational medication (SKB575) for people with asthma. It aims to see if the drug is safe and works better than a placebo when added to your regular asthma treatments.
Chengdu, SichuanAges 18–70 - NCT07718724Recruiting
Asthma treatment study for people using high-dose inhalers
This study tests if a treatment plan called GDMT can help people whose asthma is not well controlled even with high-dose inhaled steroids and long-acting bronchodilators. It is for adults who have had at least one asthma flare-up in the past year.
ChengduAges Any age - NCT07709754Recruiting
Lung stimulation for hard-to-control asthma
This trial tests a device that stimulates the lung to help people whose asthma is not controlled by standard treatments. It may offer a new option for those who still have symptoms despite using inhalers or biologic medicines.

Common questions
- Are there clinical trials for asthma?
- Yes. Clin2 currently lists 385 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.
