Brief summary: The purpose of this study is to assess if 12 weeks' treatment with GSK573719 Inhalation Powder is safe and effective compared with placebo or no active drug intake, when administered once-daily in subjects with Chronic Obstructive Pulmonary Disease (COPD).

Detailed description: Inhaled bronchodilators, such as beta 2 agonists and anticholinergics, and inhaled corticosteroids are the mainstays of therapy in patients diagnosed with COPD. Anticholinergic bronchodilators or long acting muscarinic receptor antagonists function by blocking endogenous airway smooth muscle cholinergic tone. Treatment with anticholinergics has been shown to significantly improve forced expiratory volume in 1 second (FEV1), resting and dynamic lung hyperinflation, symptoms, and exercise capacity in patients with COPD. Currently tiotropium is the only approved long acting muscarinic antagonist available for treatment of COPD.This is a multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy and safety of GSK573719 Inhalation Powder of 2 doses when administered once-daily via Novel DPI compared with placebo over a treatment period of 12 weeks in subjects with COPD. There will be a total of 8 study clinic visits conducted on an outpatient basis. Subjects who meet the eligibility criteria at Screening (Visit 1) will complete a 5 to 9 days run-in period followed by a 12-week treatment period. There will be 8 clinic visits during three of which serial spirometry will be performed . The total duration of subject participation in the study will be approximately 14 weeks.

This is a Phase III multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy and safety of GSK573719 Inhalation Powder 62.5 mcg and 125 mcg when administered once-daily via Novel DPI compared with placebo over a treatment period of 12 weeks in subjects with COPD.

Eligible subjects will be randomized 1:1:1 to receive either of the two doses of GSK573719 Inhalation Powder doses or placebo for 12 weeks.

There will be a total of 8 study clinic visits conducted on an outpatient basis. Subjects who meet the eligibility criteria at Screening (Visit 1) will complete a 5 to 9 days run-in period followed by a 12-week treatment period. Clinic visits will be at Screening, Randomization (Visit 2), Day 3 and Weeks 2, 4, 8, and 12, and 1 day after the Week 12 visit (Visits 1 to 8, respectively). A safety follow-up assessment will be conducted by telephone approximately 7 days after the end of the study treatment (FU Phone Contact). The total duration of subject participation, including the follow-up period will be approximately 14 weeks. All subjects will be provided with albuterol/salbutamol for use on an "as-needed" basis throughout the run-in and treatment periods.

Pre-dose spirometry will be conducted at each clinic visit. Six hour post-dose serial spirometry will be conducted at Visit 2 and at Visits 5 and 7. All subjects will be provided with a paper diary for completion everyday throughout the run-in period and 12-week treatment period. Subjects will use the diary to record their daily use of supplemental albuterol/salbutamol and to record any medical problems experienced and any medications used.

At Visit 2 the Baseline Dyspnea Index (BDI) will be administered. The Transition Dyspnea Index (TDI) will be administered at Visits 5, 6, and 7.

Disease specific health status will be evaluated using the St. George's Respiratory Questionnaire (SGRQ) at Visit 2 and Visits 5, 6 and 7. Vital signs (blood pressure and pulse rate), 12-lead ECGs and standard clinical laboratory tests (hematology and blood biochemistry) including pharmacokinetic samples will be obtained at selected clinic visits.

Approximately 198 subjects will be randomized to ensure at least 168 subjects complete the treatment period.
