Pivotal Trial

Summary

This trial looks at the effect of 3 inhalers on lung capacity and exercise endurance.

Who is the study for?
This trial is for adults aged 40-80 with moderate to severe COPD who are current or former smokers. They must have a BMI < 40 kg/m2, stable on COPD treatment for at least 6 weeks, and not be using oxygen therapy or have certain health conditions like untreated glaucoma, significant cancers, or recent drug abuse.
What is being tested?
The study tests the effects of two inhalers: one with Budesonide, Glycopyrronium, and Formoterol Fumarate (BGF), another with just Budesonide and Formoterol Fumarate (BFF), against a placebo. It measures how these treatments impact breathing capacity and exercise endurance in COPD patients.
What are the potential side effects?
Possible side effects include respiratory infections, throat irritation or pain, coughing, dry mouth from glycopyrronium; potential pneumonia risk from budesonide; tremors or heart palpitations from formoterol fumarate.
