NCT ID NCT06969573
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Treprostinil (inhaled)
What this could lead to
If it works, this could point toward a new way to help people with mild COPD feel less breathless during activity and exercise more comfortably.
What could go wrong
This is a very small, early pilot study with only 20 people. It is designed mainly to test feasibility, not to prove effectiveness. The drug may not improve symptoms significantly.
