Brief summary
The purpose of this study is to evaluate the lung function response to UMEC/VI, UMEC, and VI in individual patients using a cross-over design. This is a multicenter, randomized, double-blind, 3-way crossover study. Eligible subjects will be randomized to a sequence of UMEC 62.5mcg, VI 25mcg, and UMEC/VI 62.5/25mcg. All subjects will receive each treatment once-daily for 14 days, and each treatment will be separated by a 10-14 day washout period. There will be a 5-7 day run-in period prior to randomization.

The WM FEV1 was calculated using 0-6 hour post-dose measurements at Day 14 of each TP, which included pre-dose (trough value for Day 14 \[mean of the 23 and 24 hour assessments post Day 13 dosing\]) and post-dose 15 minutes (min), 30 min, and 1, 3, and 6 hours. BL is the mean FEV1 values recorded 30 min and 5 min pre-dose on Day 1 of each TP, mean BL is the mean of the BLs for each participant, and period BL is the difference between the BL and the mean BL in each TP for each participant.

Change From Baseline (BL) in Weighted Mean (WM) 0-6 Hour Forced Expiratory Volume in One Second (FEV1) Obtained Post-dose at Day 14 of Each Treatment Period (TP) by Response Type
FEV1 is a measure of lung function and the maximal amount of air that can be forcefully exhaled in one second. The WM FEV1 was derived by calculating the area under the FEV1/time curve (AUC) using the trapezoidal rule, and then dividing the value by the time interval over which the AUC was calculated. The WM FEV1 was calculated using 0-6 hour post-dose measurements at Day 14 of each TP, which included pre-dose (trough value for Day 14 \[mean of the 23 and 24 hour assessments post Day 13 dosing\]) and post-dose 15 minutes (min), 30 min, and 1, 3, and 6 hours. BL is the mean FEV1 values recorded 30 min and 5 min pre-dose on Day 1 of each TP, mean BL is the mean of the BLs for each participant, and period BL is the difference between the BL and the mean BL in each TP for each participant. Change from BL for each TP is the Day 14 value minus the BL value for that TP. Participants could have been classified as responders to both UMEC and VI.

Trough FEV1 on Treatment Day 15 is defined as the mean of the FEV1 values obtained at 23 and 24 hours after dosing on Day 14. Analysis was performed using an ANCOVA model with covariates of treatment, period, mean Baseline (BL), period BL, response type, and treatment by response type interaction. A participant is a reponder to UMEC if they were a responder to UMEC monotherapy or a responder to both UMEC monotherapy and VI monotherapy.

BL is the mean FEV1 recorded 30 min and 5 min pre-dose on Day 1 of each treatment period, mean BL is the mean of the BLs for each participant, and period BL is the difference between BL and the mean BL in each treatment period for each participant.
