Methacholine challenge test for children with asthma
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study measures how children's airways respond to a substance called methacholine to understand how asthma affects lung function. It compares children with and without asthma to help improve diagnosis and treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your child must be between 7 and 15 years old.
- Your child either has doctor-diagnosed asthma (and using daily inhaled corticosteroid for at least 6 months) or has no asthma and no breathing problems for the past 2 years.
- Your child cannot have been born very prematurely (before 32 weeks) or have other chronic heart, lung, or nerve conditions that affect breathing.
- Your child cannot be taking beta-blocker medication or have a serious illness like cancer or an active immune disease.
- You and your child must both agree to join the study and sign a consent form.

This study tests a new, low-power device worn on the body that may help diagnose asthma. It is for adults who are comfortable using mobile apps.
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.
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 Phase 2 study checks how glycopyrronium bromide works in children with asthma, including its safety and how well inhaler dosing is tolerated. It also uses breathing tests and inhaler technique checks to confirm your child meets key asthma and lung function requirements.
This study tests a new inhaled medicine, ADO-5030, to see if it helps people with mild or moderate asthma when their airways narrow (bronchoconstriction). You will be asked to breathe in a substance that can trigger asthma symptoms, and the study will check if the medicine helps prevent or reduce that reaction.
This study looks for biological “markers” that may help explain why asthma starts and how it changes over time in children. It may help your child’s doctors understand asthma better, especially for diagnosis or tracking.
