Detailed Description:
This is a randomized, double-blind, double dummy, parallel group, multicenter 24 to 52 week variable length study to assess the efficacy and safety of budesonide, glycopyrronium, and formoterol fumarate metered dose inhaler (MDI) relative to budesonide and formoterol fumarate MDI and Symbicort® pressurized MDI in adult and adolescent participants with inadequately controlled asthma. Approximately 2800 participants will be randomized globally.
