Lung valve registry shows promise for emphysema patients
NCT ID NCT04517916
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed French registry tracked 155 adults with severe emphysema or COPD who received Zephyr Valves, tiny devices placed in the lungs to help them work better. The goal was to see if the treatment safely improves breathing over 12 months. Researchers measured lung function and used CT scans to check for lung volume reduction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Zephyr Valve (a device placed in the lungs to reduce air trapping)
What this could lead to
If results are positive, this could support continued use of the Zephyr Valve as a safe and effective treatment for severe emphysema/COPD.
What could go wrong
This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may not apply to all patients, and risks like infection or valve movement exist.
