An Efficacy Study of GSK2269557 Added to Standard Care in Subjects With an Acute Exacerbation of Chronic Obstructive Pulmonary Disease

The purpose of this study is to evaluate the efficacy of GSK2269557 administered in addition to standard of care in adult subjects diagnosed with an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). Additionally study will also assess safety, tolerability and pharmacokinetic data. The total duration of the study will be 13-14 weeks including screening, treatment period and a follow up visit. Subjects will receive once daily study treatment administration starting on Day 1. Study is planned to recruit approximately 120 subjects such that approximately 100 subjects complete the study.
