NCT ID NCT07468617
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether it is safe to repeat a procedure called metered cryospray in people with COPD and chronic bronchitis who have already had it once. Only 10 participants will be enrolled. The main goal is to see if the treatment can be fully delivered and to track any serious side effects.

metered cryospray (device)
What this could lead to
If safe, this could offer a repeatable procedure to ease chronic bronchitis symptoms in COPD patients.
