FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 on Treatment Day 15 is defined as the value obtained 24 hours after the morning dose administered on Day 14. Analysis were performed using a mixed model with covariates of mean Baseline, period Baseline, treatment and period as fixed effects and participant as a random effect. Baseline is the FEV1 value recorded pre-dose on Day 1 of each treatment period; mean Baseline is the mean of the Baselines for each participant and period Baseline is the difference between the Baseline and the mean Baseline in each treatment period for each participant. Change from Baseline for each treatment period is the trough FEV1 at Day 15 minus the Baseline value for that treatment period.
