Testing a lung protein in COPD sputum samples
Part of Lungs & breathing clinical trials.
This study looks at a lung protein called MMP12 in sputum (mucus) to better understand COPD. It may help researchers learn which COPD changes are linked to disease severity and lung damage.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re 40 or older
- If you’re in the COPD group: you currently smoke or used to, with a history of more than 10 pack-years
- You have breathing test results showing COPD (post-bronchodilator FEV1/FVC under 70%) and FEV1 at least 30% of what’s expected
- You’ve had a CT scan where a lung imaging specialist confirmed emphysema
- You can do breathing tests (spirometry) and provide sputum for the study

Other trials that look related to this one.
This study looks for new measurable signs (“markers”) that can help detect emphysema earlier and more accurately. You may be asked to have breathing measurements and complete tasks if you have COPD and have had a recent chest CT scan.
This trial uses a special breathing MRI (you breathe a gas mixture) to measure how well your lungs work. It studies healthy kids and people with lung conditions like cystic fibrosis or asthma, and it may help researchers better understand lung function and flare-ups.
This study uses a special gas called xenon to take pictures of your lungs with MRI, a safe imaging method. It aims to improve lung imaging for future patients, and you may participate if you are generally healthy.
This study uses special MRI and CT scans to take very detailed pictures of the lungs in people with mild asthma. The goal is to learn more about how asthma affects the lungs, which could help develop better treatments.
This study uses special MRI scans with a gas you breathe in (xenon) and CT scans to see how well anti-fibrotic treatment is working in people with lung scarring (fibrotic interstitial lung disease). If you have this condition and are planning to start or continue treatment, this study could help doctors understand if the treatment is helping your lungs.
This study compares two ways of seeing how well your lungs work: a special MRI scan and another scan that uses a different gas. It may help researchers find which imaging test best reflects lung function in people with COPD.
