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
- NCT05831566RecruitingPhase 3
Digital coaching program for severe asthma control
This Phase 3 study tests whether an asthma care program with digital (phone-based) support helps people with severe asthma stay more stable and manage symptoms better. You may need to meet specific criteria for “severe, refractory” asthma and be willing to use a smartphone for monitoring and coaching.
Rotterdam, South HollandAges 18 years+ - NCT05903001Recruiting
Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT06068335Recruiting

Escitalopram for frequent asthma attacks
This study tests whether the antidepressant escitalopram can reduce asthma attacks in people who have frequent, severe flare-ups despite using their regular inhalers. It may help if you have moderate to severe asthma and have had 3 or more attacks needing steroids in the past year.
Dallas, TexasAges 18–75 - 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+ - NCT06278662Recruiting
Asthma treatment study for children 4 to 18 years old
This trial tests different ways to manage asthma in children. It aims to see which treatment approach works best for your child's symptoms and lung function.
Enschede, OverijsselAges 4–18 - NCT06286007Recruiting
How whooping cough and RSV affect asthma in adults
This study looks at how infections like whooping cough and RSV impact asthma symptoms and control in adults. It aims to understand if these infections make asthma worse, which could help improve future treatment and prevention.
Santiago de Compostela, A CoruñaAges 18–99 - NCT06286085Recruiting
Comparing asthma tests in Portsmouth
This study looks at different ways to test for asthma. It uses data from patients who have already been evaluated at the Portsmouth asthma service, to see which tests work best for diagnosing asthma.

Brain inflammation in severe asthma vs. healthy adults
This study uses brain scans to compare inflammation in the brain between people with severe asthma and healthy volunteers. It aims to understand how asthma may affect the brain.
Madison, WisconsinAges 18–75 - NCT06323213RecruitingPhase 3
Testing a new asthma medicine for severe asthma
This study tests an experimental drug called 610 for people with severe asthma that is not well-controlled with standard medicines. The goal is to see if adding 610 can improve asthma control and reduce flare-ups.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06360393Recruiting
Checking inhaler use with a smart spacer for severe asthma on biologics
This trial tests if a smart spacer can help people with severe asthma use their inhaler correctly and stick to their medication schedule. It’s for adults already taking biologic drugs for asthma.
Zwolle, OverijsselAges 18 years+ - NCT06372249RecruitingPhase 2
Fiber drink for asthma in kids
This trial tests whether a liquid fiber drink can help children with asthma by reducing airway inflammation. Participants will drink either fiber or a placebo and be followed for about 4–6 weeks to see if their asthma improves.
Phoenix, ArizonaAges 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 - NCT06392776Recruiting
Finding untreated asthma or COPD early
This study aims to find people with undiagnosed asthma or COPD by using a simple questionnaire and a breathing test. If you have symptoms like cough or wheeze but no prior diagnosis, you may be able to join and get early treatment.
Hamilton, OntarioAges 18 years+ - NCT06425562Recruiting
A new breathing test for asthma monitoring
This study tests a new way of measuring lung function (called impulse oscillometry) during routine asthma check-ups. It looks at whether this helps doctors decide when to change asthma medicines.
BrusselsAges 18 years+ - NCT06432790Recruiting
In-person vs online healthy living and asthma program for kids
This study compares two programs for helping children with asthma who are overweight or obese — one that is held in person and another that is offered online. It tests whether learning about healthy habits and asthma management works better when done face-to-face or on a computer.

Comparing two asthma rescue inhalers with different propellants
This study compares two versions of the common asthma rescue inhaler (salbutamol/albuterol) that use different propellants (the gas that pushes the medicine out). The goal is to see if the new propellant works as well as the current one. If you have mild asthma and are on a stable treatment plan, you may be able to join.

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.
