- Change From Baseline (BL) in Trough Forced Expiratory Volume in One Second (FEV1) on Day 169 (Week 24) [ Time Frame: Baseline and Day 169 ]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 measurements were taken electronically by spirometry on Days 2, 28, 56, 84, 112, 140, 168, and 169. Baseline is defined as the mean of the assessments made 30 minutes (min) pre-dose and 5 min pre-dose on Treatment Day 1. Trough FEV1 is defined as the mean of the FEV1 values obtained at 23 and 24 hours (hr) after the previous morning's dosing (ie., trough FEV1 on Day 169 is the mean of the FEV1 values obtained 23 and 24 hr after the morning dosing on Day 168). Change from Baseline at a particular visit was calculated as the trough FEV1 value at that visit minus the Baseline value. Analysis was performed using a repeated measures model with covariates of treatment, Baseline (mean of the two assessmentsmade 30 min and 5 min pre-dose on Day 1), smoking status, center group, day, and day by Baseline and day by treatment interactions.
- Change From Baseline (BL) in Weighted Mean (WM) 0-6 Hour FEV1 Obtained Post-dose at Day 168 [ Time Frame: Baseline and Day 168 ]FEV1 is a measure of lung function and is defined as 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 was calculated at Days 1, 84, and 168 using the 0-6-hour post-dose FEV1 measurements collected on that day, which included pre-dose (Day 1: 30 minutes [min] and 5 min prior to dosing; other serial visits: 23 and 24 hours after the previous morning dose) and post-dose at 15 min, 30 min, 1 hour, 3 hours, and 6 hours. Change from BL at a particular visit was calculated as the WM value at that visit minus the BL value. Analysis was performed using a repeated measures model with covariates of treatment, BL (mean of the two assessments made 30 min and 5 min pre-dose on Day 1), smoking status, center group, day, and day by BL and day by treatment interactions.

This is a Phase IIIb multicenter, randomized, double-dummy, parallel group study to evaluate the efficacy and safety of UMEC/VI Inhalation Powder (62.5/25 mcg) when administered once-daily via a novel dry powder inhaler (DPI) compared with tiotropium (18 mcg) administered once-daily via the HandiHaler over a treatment period of 24 weeks in subjects with COPD. Eligible subjects will be randomized 1:1 to UMEC/VI Inhalation Powder (62.5/25 mcg), or tiotropium (18 mcg) for 24 weeks.
There will be a total of 10 study clinic visits conducted on an outpatient basis. Subjects who meet the eligibility criteria at Screening (Visit 1) will complete a 7- to 10-day run-in period followed by a 24-week treatment period. Clinic visits will be at Screening, Randomization (Day 1), Day 2 and after 4, 8, 12, 16, 20 and 24 weeks, and 1 day after the Week 24 visit (Visit 1 to Visit 10, respectively). Additionally a safety Follow-Up assessment will be conducted either by phone call or clinic visit where required approximately 7 days after the end of the study treatment (Visit 10 or Early Withdrawal, if applicable). The total duration of subject participation, including the Follow-Up will be approximately 26 weeks.
