The Mean Change From Baseline to 24 Hour Post-dose (Trough) Forced Expiratory Volume in 1 Second (FEV1)
FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. Change from baseline to 24 hour post dose trough FEV1 after 14 days of treatment was analyzed using Analysis of Covariance (ANCOVA) adjusting for treatment and region with baseline FEV1 as a covariate.
Time frame: Baseline (prior to first dose) and Day 15 (24 hours after last dose)
Population: The intent-to-treat population (ITT) population consisted of all randomized patients who had a baseline and at least one post-dose FEV1 measurement. The analysis only includes patients with non-missing data.
