How a three-part inhaler helps people with severe lung disease

This is a real-world study watching how Breztri/Trixeo works in everyday life for people with moderate to severe COPD. The study will follow about 1,400 patients across multiple countries who are already being prescribed this three-part inhaler (which combines a steroid, a long-acting muscle relaxant, and a long-acting bronchodilator) to see how it affects their symptoms, how often they have flare-ups, and how it impacts their quality of life.

COPD is a serious lung disease that causes progressive difficulty breathing and can lead to life-threatening flare-ups. While this medication has been approved by regulators, researchers want to understand how well it actually works for different patients in real-world medical settings, especially in parts of the world with fewer healthcare resources.
