Breathing and blood flow study for adults with asthma
Treatments studied
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study looks at how asthma affects air flow and blood flow in your lungs. You may join if you use daily asthma control medicine and your breathing test shows room for improvement even after using a rescue inhaler.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been told by a doctor that you have asthma
- You are between 18 and 75 years old
- You use a daily inhaled steroid (controller) medication at the same dose for at least 3 months
- Your breathing test (FEV1) is less than 80% of normal, but improves by at least 10% after using a rescue inhaler
- You do not smoke cigarettes or vape nicotine, and you have not smoked more than a pack per day for 10 years

Other trials that look related to this one.
This study looks at airway samples from people with asthma and healthy volunteers. It helps researchers understand what causes airway problems and could lead to better treatments.
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.
This study looks at how weight and blood-sugar/fat changes in the body may affect the airways in people with asthma. You may be asked to complete breathing tests and possibly an airway procedure (bronchoscopy) to help researchers compare groups.
This trial uses special imaging to look at how air moves through your lungs. It may help doctors understand asthma better and could lead to better treatments.
This Phase 4 study looks at what causes breathing airways to narrow during asthma worsening, in people with stable, treated asthma. It may help improve how clinicians understand and manage asthma flare-ups.
This trial uses advanced imaging to study the shape of airways in adults with asthma who have active symptoms and inflammation. It aims to find out if certain airway shapes affect how well treatments work, which could lead to more personalized asthma care.
