A Study to Investigate the Effect on Lung Function of BDA Formulated With a New Propellant (HFO) Compared With an Approved Asthma Treatment (BDA With HFA Propellant) in Participants With Asthma

The purpose of this study is to assess the PD equivalence of the approved asthma combination therapy, BDA, delivered using the proposed replacement propellant HFO compared with BDA delivered using the currently approved propellant HFA in participants with asthma. The study duration for each participant will be approximately 14 to 15 weeks and will consist of: 1. A screening and placebo run-in period of approximately 2 weeks prior to the first dose of study intervention 2. 3 treatment periods of 4 weeks each 3. A final safety follow-up visit via telephone contact approximately 5 days after the final dose of study intervention Participants will attend in-clinic visits 2 weeks apart during the screening/run-in period (Visits 1 and 2) and then every 4 weeks during the treatment period (Visits 3, 4, and 5).
