Study breathing limits in overlap asthma-COPD
Part of Lungs & breathing clinical trials.
This trial looks at what causes breathing to become harder when you blow air out in people with asthma-COPD overlap, and in some people with emphysema or bronchiectasis. It may help researchers better understand your condition’s breathing problem and how to target it.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have asthma-COPD overlap (asthma and COPD features together)
- You are a smoker (not a non-smoker)
- You have smoked more than 15 “pack-years” (a way of measuring smoking history)
- You have emphysema from smoking or COPD/bronchitis plus bronchiectasis that is related to smoking
- You do not have other major lung or whole-body illnesses that could explain symptoms
- You do not have pulmonary fibrosis (scarring in the lungs)

This study follows people with COPD over time to better understand their lung health and how it changes. It may help researchers and doctors learn what factors affect breathing and long-term outcomes.
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
This trial tests how well different breathing tests measure relief from shortness of breath in people with asthma or COPD. It may help doctors find better ways to check how well treatments are working.
This trial looks at how long-term health conditions like heart disease, diabetes, or high blood pressure might affect breathing problems. The goal is to better understand and help people with both issues.
This study follows people who currently smoke and people who may have newly found COPD (chronic obstructive lung disease) based on breathing test results. It aims to better understand lung disease in real life and what it means for health over time.
This study looks at chronic airway diseases like asthma and COPD. Researchers want to learn more about how these conditions affect people and may explore treatments. You might join if you have asthma or COPD and no other major health issues.
