This study looks at the tiny germs in your airways (airway microbiota) to better understand different asthma “types” and what might drive symptoms. It may help researchers find more personalized approaches to asthma care by learning how lung bacteria relate to your asthma features.
ShatinAges 18 years+ - NCT04796844Recruiting
Asthma real-world study for adults in other health studies
This study follows adults with asthma in real life to better understand asthma care and outcomes. You may be invited if you already joined another asthma-related or health-related observational study and don’t have certain major lung or health conditions.

Vitamin D for preventing asthma-like flare-ups in young children
This study tests whether a high-dose vitamin D supplement can help preschool children have fewer acute asthma-like symptoms (coughing, wheezing, or trouble breathing) that require hospital care. It may help by supporting the immune and airway system, but you can only join if the child meets several safety and treatment criteria.
Gentofte Municipality, GentofteAges 1 year–5.9 years - NCT05259904RecruitingPhase 2
L-citrulline supplement for deployment-related asthma symptoms
This trial studies whether an L-citrulline supplement can improve asthma control in people who developed persistent asthma symptoms after military deployment. If you qualify, you may be asked to track symptoms and breathing test results to see if the supplement helps.
Denver, ColoradoAges 18–70 - NCT05632081Recruiting
Testing a new asthma control step-up approach
This trial studies how stepping up asthma treatment affects asthma control in people with mild to moderate asthma. You may be asked to use study inhalers correctly and track symptoms and lung tests to see if control improves.
DammamAges 12–80 - NCT05937334Recruiting
Long-term study of asthma in adults in China
This study follows adults with asthma over about 2 years to learn more about asthma and how people do over time. If you qualify, you’ll be asked to join regular visits and follow the study plan.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05945355Recruiting
Study of breathing training for children with asthma
This study looks at how an asthma-specific breathing training program affects children’s breathing and asthma control. It may help your care team understand who could benefit from inspiratory (breathing-in) training.
Durham, North CarolinaAges 6–17 - NCT05991115Recruiting
Hospital to home study for children with asthma
This study helps families whose child is in the hospital for asthma. It aims to make the transition home smoother and reduce asthma-related health differences.
Washington D.C., District of ColumbiaAges 4–12 - NCT06044051Recruiting
Severe infant asthma and the lung microbiome study
This study looks at the bacteria (microbiome) in the airways of infants under 2 years old with severe asthma. It aims to understand how these bacteria might affect the disease.
RouenAges Up to 2 years - NCT06137040RecruitingEarly Phase 1
Early IV Magnesium for Moderate Asthma in Children
This trial tests whether giving magnesium sulfate through an IV early in the emergency room helps children aged 5–17 who are having a moderate asthma attack. It aims to improve breathing and reduce the need for hospital stays.
Oklahoma City, OklahomaAges 5–17 - NCT06273072RecruitingPhase 2
Metformin for asthma in overweight adults
This trial tests whether the diabetes drug metformin can help people with asthma who are also overweight or obese. The goal is to see if it improves asthma control and reduces the need for rescue medications.
Baltimore, MarylandAges 18 years+ - NCT06314477Recruiting
CPAP treatment for severe uncontrolled asthma with sleep apnea
This trial tests if CPAP (a mask that helps you breathe at night) can improve asthma control in people who have both severe uncontrolled asthma and sleep apnea (a condition where breathing stops and starts during sleep). You should not have been hospitalized for asthma in the last month.
Barcelona, SpainAges 18 years+ - NCT06388460Recruiting
Asthma Link study for children with asthma
This study tests a program called 'Asthma Link' to help children with asthma take their daily medicine more consistently. It is for children ages 5–14 whose asthma is not well controlled and who sometimes forget their medication.

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.
