COPD is characterized by an airflow limitation, which is not fully reversible, usually progressive and accompanied by chronic cough, sputum production and dyspnea, which can be a major cause of disability and anxiety associated with the disease. In addition, COPD is associated with poor health-related quality of life (HRQoL). Pharmacologic therapy is used to improve lung function, reduce symptoms, reduce the frequency and severity of exacerbations, and also to improve health status and exercise tolerance. This is a multi-center, randomized, double blind, double dummy, 3-arm parallel group study to compare umeclidinium/vilanterol (62.5/25 microgram \[mcg\], once daily), umeclidinium (62.5 mcg, once daily), and salmeterol (50 mg, twice daily) in male and female subjects with COPD. The primary purpose of this study is to demonstrate improvements in lung function for subjects treated with UMEC/VI compared with UMEC for 24 weeks. Approximately 2424 subjects will be randomized across 3 parallel arms in 1:1:1 ratio. Subjects will be stratified based on long-acting bronchodilator usage during the run-in period (none, one or 2 long-acting bronchodilators per day). Subjects will receive either UMEC/VI inhalation powder (62.5/25 microgram \[mcg\] once daily) administered via the ELLIPTA® dry powder inhaler (DPI) and placebo twice daily via DISKUS® DPI; or UMEC (62.5 mcg once daily) administered via the ELLIPTA DPI and placebo twice daily via DISKUS DPI or salmeterol (50 mcg twice daily \[BID\]) administered via the DISKUS DPI and placebo once daily via ELLIPTA DPI. The duration of the study will be 29 to 31 weeks including a pre-screening period of 2 weeks, run-in period of 4 weeks, treatment period of 24 weeks and follow-up period of 1 week.

ELLIPTA DPI inhaler will contain two individual blister strips with 30 blisters per strip; the first strip contains umeclidinium bromide (62.5 mcg per blister) blended with lactose monohydrate and magnesium stearate and second strip contains vilanterol trifenatae (25 mcg per blister) blended with lactose monohydrate and magnesium stearate.
The ELLIPTA inhaler will contain one blister strip, which will have 30 blisters of umeclidinium bromide (62.5 mcg).
The DISKUS inhaler will contain one blister strip, which will have 60 blisters of salmeterol xinafoate (50 mcg). The DISKUS will provide a total of 60 doses (60 blisters) and will deliver, when actuated, the contents of a single blister strip.
Lactose dry powder will be administered using ELLIPTA for both treatment periods. ELLIPTA DPI inhaler will contain two individual blister strips with 30 blisters per strip; containing lactose dry powder.
Lactose dry powder will be administered using DISKUS for both treatment periods. The DISKUS inhaler will contain one blister strip, which will have 60 blisters of lactose dry powder. The DISKUS will provide a total of 60 doses (60 blisters) and will deliver, when actuated, the contents of a single blister strip.
