Overview
Brief Summary
The purpose of this 52-week study is to evaluate the long-term safety (in terms of adverse events, COPD exacerbations, laboratory, ECG, and Holter findings, vital signs, use of rescue medication and lung function) of GSK573719/GW642444 Inhalation Powder 125/25mcg in subjects with COPD. The long-term safety of GSK573719 Inhalation Powder 125mcg will also be evaluated. A placebo arm is included to evaluate these products compared to an inactive control.
Detailed Description
Several studies have demonstrated the efficacy and safety of combining an individual LABA compound plus an individual LAMA compound in COPD. These studies have shown the combination of these two products to be superior to either agent alone on a variety of outcomes in COPD. The beneficial effects of this combination regimen are likely due to the different mechanisms of action of the two bronchodilators (smooth bronchial muscle relaxation from activation of beta2 receptors from the LABA product and inhibition of acetylcholine-mediated smooth bronchial muscle contraction via blockade of muscarinic receptors from the LAMA product). The availability of a LABA/LAMA combination in one product instead of two individual products is a technical and therapeutic advancement in the pharmacological armamentarium for COPD and may lead to increased patient compliance due to once-daily administration. The purpose of this 52-week study is to evaluate the long-term safety (in terms of adverse events, COPD exacerbations, laboratory, ECG, and Holter findings, vital signs, use of rescue medication, and lung function) of GSK573719/GW642444 Inhalation Powder 125/25mcg in subjects with COPD. The long-term safety of GSK573719 Inhalation Powder 125mcg will also be evaluated. A placebo arm is included to evaluate these products compared to an inactive control. All treatments will be delivered once-daily via the nDPI. This study will establish the long-term safety profile of GSK573719/GW642444 Inhalation Powder 125/25mcg once-daily in subjects with COPD. The safety profile of GSK573719 Inhalation Powder125mcg once-daily will also be evaluated.

Outcomes
Primary Outcomes
Number of Participants With Any On-treatment Adverse Event (AE) or Any Serious Adverse Event (SAE)
Time Frame: From the start of study drug up to 52 weeks
An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury with hyperbilirubinaemia. Medical or scientific judgment was to have been exercised in other important medical events. AEs with an onset on or after the date of the first dose of study drug and up to 1 day after the date of the last recorded dose of study drug were considered to be on-treatment AEs, Refer to the general AE/SAE module for a complete list of AEs and SAEs.
