This is a phase III multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of GSK573719/GW642444 Inhalation Powder, GSK573719 Inhalation Powder, GW642444 Inhalation Powder and Placebo when administered once-daily via a Novel Dry Powder Inhaler over a 24-week treatment period in subjects with COPD. Subjects who meet eligibility criteria at Screening (Visit 1) will complete a 7 to14 day run-in period followed by a randomization visit (Visit 2) then a 24-week treatment period. There will be a total of 9 clinic study visits. A follow-up phone contact for adverse event assessment will be conducted approximately one week after the last study visit (Visit 9 or Early Withdrawal). The total duration of subject participation in the study will be approximately 27 weeks. A subset of subjects at selected sites will also perform 24-hour serial spirometry and Holter monitoring during the study and provide serial blood samples for pharmacokinetic analysis. Sparse pharmacokinetic sampling for population pharmacokinetic analyses will be obtained from non-subset subjects. The primary measure of efficacy is clinic visit trough (pre-bronchodilator and pre-dose) FEV1 on Treatment Day 169. Safety will be assessed by adverse events, 12-lead ECGs, vital signs, clinical laboratory tests, and 24 hour Holter monitoring (subset only).

Primary Outcome Measures:
  • Change From Baseline (BL) in Trough Forced Expiratory Volume in One Second (FEV1) on Day 169 (Week 24) [ Time Frame: Baseline and Day 169 ] [ Designated as safety issue: No ]
    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, 168, and 169. Baseline is defined as the mean of the assessments made 30 minutes pre-dose and 5 minutes pre-dose on Treatment Day 1. Trough FEV1 is defined as the mean of the FEV1 values obtained at 23 and 24 hours after the previous morning's dosing (ie., trough FEV1 on Day 169 is the mean of the FEV1 values obtained 23 and 24 hours after the morning dosing on Day 168). Change from Baseline at a particular visit was calculated as the trough FEV1 at that visit minus Baseline. Analysis was performed using a repeated measures model with covariates of treatment, Baseline , smoking status, center group, day, and day by Baseline and day by treatment interactions. ITT=Intent-to-Treat; par.=participants.

Secondary Outcome Measures:
  • Mean Transition Dyspnea Index (TDI) Focal Score at Day 168 (Week 24) [ Time Frame: Day 168 (Week 24) ] [ Designated as safety issue: No ]
    Considered an 'other' endpoint by the FDA. The TDI is an interviewer-administered instrument which measures the changes in the participant's dyspnea from Baseline. This questionnaire was collected on Days 28, 84 and 168. The scores in the TDI evaluate ratings for 3 different categories (functional impairment, magnitude of task in exertional capacity, and magnitude of effort). TDI scores ranged from -3 (major deterioration) to +3 (major improvement); total score = -9 to 9. Analysis was performed using a repeated measures model with covariates of treatment, Baseline dyspnea index (BDI) focal score,smoking status, center group, day, day by BDI focal score and day by treatment interactions.

  • Change From Baseline in Weighted Mean (WM) 0-6 Hour FEV1 Obtained Post-dose at Day 168 [ Time Frame: Baseline and Day 168 ] [ Designated as safety issue: No ]
    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, 28, 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 Baseline at a particular visit was calculated as the WM at that visit minus Baseline. Analysis was performed using a repeated measures model with covariates of treatment, Baseline (mean of the two assessments made 30 min and 5 min pre-dose on Day 1), smoking status, center group, day, and day by Baseline and day by treatment interactions.

Other Outcome Measures:
  • Change From Baseline in the Mean Shortness of Breath With Daily Activities (SOBDA) Score for Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    The newly developed SOBDA questionnaire assesses dyspnea or shortness of breath (SOB) with daily activities. The SOBDA questionnaire is made up of 13 items completed by the participant (par.) each evening prior to bedtime, when the par. is instructed to reflect on the current day's activities. The daily score is computed as the mean of the scores on the 13 items (>=7 items must have non-missing responses for this to be calculated). The par. is assigned a weekly mean SOBDA score ranging from 1 to 4 (greater scores indicate more severe breathlessness with daily activities) based on the mean of 7 days of data (>=4 of 7 days must be completed for a weekly mean to be calculated). Change from BL is the mean weekly SOBDA score minus BL. Analysis was performed using MMRM with covariates of treatment, BL (mean score in the week prior to treatment), smoking status, center group, week, week by BL and week by treatment interactions. This MMRM analysis only included Weeks 4, 8, 12, and 24.
