Zephyr Valve study for severe COPD patients in Japan
Part of Lungs & breathing clinical trials.
This study is tracking the real-world use of the Zephyr Valve, a device that helps people with severe COPD breathe easier. It will check if the valve is safe and works well for people in Japan who have been chosen for this treatment by their doctor.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have completed a breathing rehab program within the last 6 months.
- You must have not smoked for at least 4 months.
- You must have a doctor's order for a test showing your lungs are overinflated and your breathing capacity is between 15% and 45% of normal.
- You must be able to walk between 100 and 500 meters in 6 minutes.
- You must have shortness of breath that limits daily activities (score of 2 or higher on a standard scale).
- You must have a test confirming there is little to no air leakage between the lung lobes where the valve will be placed.

Other trials that look related to this one.
Researchers want to see if a bronchoscopic lung volume reduction procedure with Zephyr valves changes how much oxygen your body uses during simple tasks. You may be eligible if you are scheduled for this valve treatment and do not rely on constant oxygen for daily activities.
This trial tests whether placing ZEPHYR® valves in two stages reduces the risk of a collapsed lung (pneumothorax) compared to the usual one-stage procedure. It is for people with severe emphysema who have already quit smoking and meet specific lung function criteria.
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 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.
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 trial tests a new implant for people with severe emphysema. It aims to see if the implant can help you breathe easier and walk farther.
