Brief summary

The Purpose of this study is to evaluate the 24-hour spirometry effect Forced Expiratory Volume in One second (FEV1) of 3 doses of Fluticasone Furoate (FF)/GW642444 Inhalation Powder at the end of a 28-day treatment period in subjects with Chronic Obstructive Pulmonary Disease (COPD) compared with placebo. Other objectives are to assess additional efficacy, plus the safety, pharmcodynamics and tolerability of concurrent treatment with Fluticasone Furoate (FF) plus GW642444 when administered at three dose levels for 28 days in subjects with COPD and to assess the steady-state pharmacokinetic profile of Fluticasone Furoatee (FF) and GW642444 at the end of each treatment period.

Inclusion criteria

* Outpatient/Inpatient; Male or female subjects * Subjects must give their signed and dated written informed consent to participate. * A female is eligible to enter and participate in the study if she is of: Non-child bearing potential (i.e. physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being amenorrhoeic, \> 45 years, in the absence of hormone replacement therapy. However in questionable cases, a blood sample with FSH \>40MIU/ml and estradiol \< 40pg/ml (\<140 pmol/L) is confirmatory. OR Child bearing potential, has a negative pregnancy test at screening, and agrees to one of the following acceptable contraceptive methods used consistently and correctly (i.e. in accordance with the approved product label and the instructions of the physician for the duration of the study - screening to follow-up contact): * Complete abstinence from intercourse from screening until the follow-up contact; or * Male partner is sterile (vasectomy with documentation of azoospermia) prior to female subject entry into the study, and this male partner is the sole partner for that subject; or * Implants of levonorgestral inserted for at least 1 month prior to the study medication administration but not beyond the third successive year following insertion; or * Injectable progestogen administered for at least 1 month prior to study medication administration; or * Oral contraceptive (combined or progestogen only) administered for at least one monthly cycle prior to study medication administration; or * Double barrier method: condom or occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository); or * An intrauterine device (IUD), inserted by a qualified physician, with published data showing that the highest expected failure rate is less than 1% per year; or * Estrogenic vaginal ring; or * Percutaneous contraceptive patches. * Age: ≥40 years of age at Screening (Visit 1). * COPD diagnosis: Subjects with a clinical history of COPD in accordance with the following definition by the American Thoracic Society/European Respiratory Society \[Celli, 2004\]: COPD is a preventable and treatable disease characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and is associated with an abnormal inflammatory response of the lungs to noxious particles or gases, primarily caused by cigarette smoking. Although COPD affects the lungs, it also produces significant systemic consequences. * Tobacco use: subjects with a current or prior history of ≥10 pack-years of cigarette smoking at Screening (Visit 1). Former smokers are defined as those who have stopped smoking for at least 6 months prior to Screening (Visit 1). Note: Pipe and/or cigar use cannot be used to calculate pack year history. Number of pack years = (number of cigarettes per day/20)) x number of years smoked * Severity of Disease: * Subject with a measured post-albuterol/salbutamol FEV1/FVC ratio of ≤0.70 at Screening (Visit 1). \[Pelligrino, 2005\] * Subjects with a measured post-albuterol/salbutamol FEV1 ≤ 70% of predicted normal values calculated using NHANES III reference equations \[Hankinson, 1999\] at Screening (Visit 1). Post-bronchodilator spirometry will be performed approximately 10-15 minutes after the subject has self-administered 4 inhalations (i.e. total 400mcg.) of albuterol/salbutamol via an MDI with a valved-holding chamber. The FEV1/FVC ratio and FEV1 percent predicted values will be calculated by the centralized spirometry equipment. * Dyspnea: Achieved a score of ≥2 on the Modified Medical Research Council Dyspnea Scale (mMRC, 0-4 scale) at Screening (Visit 1).

Exclusion criteria

* Pregnancy: Women who are pregnant or lactating or are planning on becoming pregnant during the study. * Asthma: Subjects with a current diagnosis of asthma.

Outcome results

Primary

Time-adjusted Area Under the Curve (AUC) (i.e., Weighted Mean) for 24-hour Serial Forced Expiratory Volume in One Second (FEV1) at the End of Each 28-day Treatment Period

FEV1 is defined as the amount of air that can be forcibly exhaled from the lungs in the first second of a forced exhalation. The weighted mean was calculated from pre-dose FEV1 (calculated as the mean of the -30 and -5 minute measurements) and post-dose FEV1 after 5, 15, 30, and 60 minutes and after 2, 4, 6, 8, 12, 16, 20, 22, 23, and 24 hours. Data are provided as the Least Squares Mean of the weighted mean for all three treatment periods. Analysis was performed using a mixed effects model with covariates of period treatment group, period Baseline, mean Baseline (defined as the mean of all available period Baseline FEV1 values), and period as fixed effects and participant as a random effect.

Time frame: Pre-dose and the end of each 28-day treatment period (up to 19 weeks)

Population: Intent-to-Treat (ITT) Population: all participants who were randomized to and received at least one dose of trial medication in any treatment period. Only those participants available at the indicated time points were assessed.

Change From Period Baseline in Clinic Visit Trough FEV1 at the End of Each 28-day Treatment Period

Trough FEV1 is defined as the mean of the 23- and 24-hour post-dose assessments. For each treatment period, period Baseline is defined as the mean of the -30 and -5 minute measurements taken on Period Day 1. Mean Baseline FEV1 for a given participant is defined as the mean of all available period Baseline FEV1 values. Data are presented as the mean of change from Baseline for all three treatment periods. Change from Baseline was calculated as the value at Period Day 29 minus the value at Baseline. Analysis was performed using a mixed effects model with covariates of period treatment group, period Baseline, mean Baseline, and period as fixed effects and participant as a random effect.

Time frame: From Baseline to the end of each 28-day treatment period (up to 19 weeks)

Population: ITT Population. Only those participants available at the indicated time points were assessed.
