About this study

This is multicenter, randomized, double-blind, double-dummy, placebo-controlled, three-way cross-over, incomplete block design study to evaluation of 5 doses of GSK573719 administered once-daily and 3 doses of GSK573719 administered twice-daily over 14 days in subjects with COPD and will include tiotropium as an open-label active control. The pharmacokinetic profile of GSK573719 will also be evaluated.

Primary outcomes

  1. Change From Baseline in Trough Forced Expiratory Volume in One Second (FEV1) at Day 15 of Each Treatment Period

    Time frame: Baseline and Day 15 of each treatment period (up to Study Day 71)

    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.

Secondary outcomes

  1. Change From Baseline (BL) in Weighted Mean FEV1 Over 0 to 24 Hours Obtained Post-dose on Day 14 of Each Treatment Period

    Time frame: Baseline and Day 14 of each treatment period (TP; up to Study Day 70)

    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 weighted mean 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 weighted mean FEV1 was calculated using 0-24 hour (h) post-dose measurements at Day 14 of each treatment period, which included pre-dose and post-dose 1, 3, 6, 9, 12, 13, 15, 18, 21 and 24 hours. Analysis performed using a mixed model with covariates mean BL, period BL, treatment and period as fixed effects and participant as a random effect. BL is the FEV1 value recorded 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 trough FEV1 at Day 15 minus the BL value for that TP.

  2. Change From Baseline (BL) in Serial FEV1 Over 0-28 Hours After the Morning Dose at Day 14 of Each Treatment Period

    Time frame: Baseline and Day (D) 14 of each treatment period (TP; up to Study Day 70)

    Serial FEV1 for OQ dosing is recorded at the pre-AM dose (time 0 h) and at 1, 3, 6, 9, 12,13, 15, 18, 21, 24 and 28 hs after the AM dose on D 14. For BID dosing, the 12 h AM dose corresponds to the pre-PM dose, 13 h AM dose corresponds to the 1 h PM dose, 15 h AM dose corresponds to the 3 h PM dose, 18 h AM corresponds to the 6 h PM dose, 21 h AM dose corresponds to 9 h PM dose, 24 h AM dose corresponds to the 12 h PM dose and 28 h AM dose corresponds to the 16 h PM dose in the table. Analysis performed using a mixed model with covariates of mean BL, period BL, trt, period, time, time by period BL interaction, time by mean BL interaction and time by trt interaction as fixed effects and par. as a random effect. BL is the FEV1 value recorded pre-dose on D 1 of each TP; mean BL is the mean of the BLs for each par. and period BL is the difference between the BL and the mean BL in each TP for each par. Change from BL for each TP is the trough FEV1 at Day 15 minus the BL value for that TP.
