Study Endpoints

Primary Endpoints

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Area Under the Curve 0 to 3 Hours (AUC0-3) at Week 12
At Week 12

Change from baseline in forced expiratory volume in 1 second (FEV1) area under the curve 0 to 3 hours (AUC0-3) at Week 12. FEV1 AUC0-3 is calculated from 0-3 hours post-dose using the trapezoidal rule, divided by the observation time to report the result in liters. Treatment policy is implemented to handle all intercurrent events with the exception of initiation of new asthma therapy or administration of prohibited medications thought to impact efficacy in conjunction with premature discontinuation of randomised study intervention, for which the composite strategy is implemented.
