Who this trial is looking for
This trial is looking for current or former smokers with COPD, emphysema, and asthma-COPD overlap. Participants will help researchers understand why some people have trouble exhaling air.
Are You a Good Fit for This Trial?
You may be able to join if
- I have asthma-COPD overlap
- I have emphysema and a smoking history of more than 15 pack years
- I have COPD or bronchitis and a smoking history of more than 15 pack years
You may not be able to join if
- I am a non-smoker
- I have another pulmonary diagnosis
- I have pulmonary fibrosis

About This Trial
The purpose of this cross-sectional, observational study is to evaluate the site and mechanism(s) for expiratory airflow limitation in chronic, treated, current or former smokers (\>15 pack years) with COPD, Emphysema, and Asthma-COPD Overlap with mild to severe expiratory airflow limitation. Treatment may include short and long acting inhaled beta2agonists, short and long acting inhaled muscarini…
