Lung valve treatment for emphysema
Part of Lungs & breathing clinical trials.
This trial tests a small silicone valve placed in your airways to help you breathe better if you have emphysema. It may be an option if you have severe breathing problems and are not getting enough relief from medicine alone.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been diagnosed with emphysema (damaged air sacs in the lungs) based on scans and symptoms.
- You have not smoked for at least 4 months before joining the study.
- Your body mass index (BMI) is under 35, meaning you are not severely obese.
- Your breathing medicine routine has been steady and working well for you.
- Your lung function test (FEV1) shows severe damage, between 15% and 45% of what is normal for your age and height.
- You have very little air trapped in your lungs (residual volume less than 175% of normal) and no extra air channels in the treated area.

This study tests whether placing tiny valves in the airways can help people with severe COPD breathe easier. It is for people who still have trouble breathing despite quitting smoking and completing pulmonary rehab.
This trial compares two methods to find the most affected area of your lungs for placing endobronchial valves, which can help you breathe easier. It is for people with severe emphysema who have quit smoking and meet specific lung function measurements.
This study compares two ways to reduce lung “overinflation” in people with severe emphysema: surgery (LVRS) or a bronchoscopy procedure (BLVR). It aims to see which approach works best and is safest for eligible patients.
This registry study follows adults with severe emphysema who have shortness of breath and low natural “backup” airflow between parts of the lung. It may help better understand how a specific FDA-approved treatment works for the right patients over time.
This trial tests an implantable artificial bronchus to help people with severe emphysema breathe easier. It's for those who have stable COPD, can walk 100–400 meters in 6 minutes, and haven't smoked for at least 4 months.
This study tests a bronchoscopic treatment to release trapped air in severely hyperinflated lungs caused by emphysema. It may help you breathe easier if you have advanced COPD and meet specific lung function and imaging criteria.
