NCT ID NCT06969573

First seen Jun 27, 2026 · Last updated Jul 09, 2026 · Updated 2 times

Summary

This small pilot study tests whether an inhaled medication called Treprostinil can reduce breathlessness and improve exercise ability in people with mild COPD. Twenty participants will take either the drug or a placebo and undergo lung function tests, exercise tests, and imaging. The goal is to see if this approach is worth studying further.
