A Study to Assess the Pharmacokinetics and Safety of Budesonide, Glycopyrronium, & Formoterol (BGF) Metered Dose Inhaler (MDI) With a Next-Generation Propellant (NGP) With a Spacer, BGF MDI Hydrofluoroalkane (HFA) With a Spacer, as Well as BGF MDI NGP Without a Spacer

This study aims to assess the effect on total systemic exposure and to characterize exposure BGF MDI HFO with a spacer compared to without a spacer; also, to demonstrate that total systemic exposure of BGF when administered as MDI HFO with a spacer is not greater than BGF MDI HFA with a spacer.
