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

Inclusion Criteria: * Participant must be ≥ 18 years of age at the time of signing the ICF. * Participants who have physician diagnosed asthma as defined by GINA for at least 12 months prior to Visit 1. * Eligible participants are on either a) no daily inhaled maintenance therapy or b) daily inhaled maintenance therapy with low-dose ICS or low-dose ICS-LABA. Participants who are on low-dose ICS maintenance therapy are required to be stable on therapy for a minimum of 3 months prior to Visit 1; participants using low-dose ICSLABA maintenance regimens are required to be stable on therapy for a minimum of 6 months prior to Visit 1. * Participants with a pre-bronchodilator FEV1 of ≥ 60% and \< 90% predicted normal at Visit 1 or Visit 1a. * Participants with a pre-dose FEV1 of ≥ 60% and \< 90% predicted normal at Visit 2 that is within ± 20% of their Visit 1 pre-bronchodilator FEV1. * Participants who demonstrate bronchodilator responsiveness defined as a \> 12% and \> 200 mL increase in FEV1 relative to baseline following administration of study provided SABA at Visit 1 or Visit 1a. * Participants able to demonstrate acceptable spirometry performance as defined by the acceptability and repeatability criteria in the ATS/ERS Standardization of Spirometry 2019 update * Participants who are willing and, in the opinion of the investigator, able to adjust current asthma therapy, as required by the protocol. * Participants with a body mass index \< 40 kg/m2. * Females must not be of ch…
