Checks for hidden small airways blockage in cystic fibrosis
Part of Lungs & breathing clinical trials.
This trial looks for early, “hidden” breathing test abnormalities in people with cystic fibrosis who have normal routine lung test results. It may help researchers find blockage in smaller airways before it shows up on standard tests.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a diagnosis of cystic fibrosis.
- Your routine breathing test (spirometry) done before a bronchodilator shows normal results.
- Your lung volume/strength measures are normal: FEV1 and FVC.
- Your ratio of airflow (FEV1/FVC) is normal.
- You should not have abnormal spirometry results before using a bronchodilator.

This trial compares physical abilities between children with cystic fibrosis and healthy children. It aims to find differences that could lead to better care and therapies.
This study tests a new method to detect bacteria in the lungs of people with cystic fibrosis (CF) by analyzing mucus samples. It aims to improve how we diagnose and treat lung infections.
This trial studies how well a non-invasive lung test can show lung involvement in people with asthma (especially IgE-related asthma) and people with cystic fibrosis. You might benefit by getting extra lung assessments without invasive procedures.
This study tests a new way to spot early signs of blocked airways in people with COPD during a routine breathing test. The goal is to catch problems sooner and help guide treatment.
This study looks for simple signals (markers) that may show whether cystic fibrosis treatments are working. It includes people who take CF “modulator” medicines like ivacaftor, people who don’t, and people whose cystic fibrosis was ruled out after testing.
This study tracks the natural course of cystic fibrosis in young children (under 6) and healthy babies over time. It aims to understand how the disease changes in the era of modern treatments, which could help improve care and guide future therapies.
