Primary Outcome Measures :
  1. FEV1 area under the curve for the time period of 0 to 12 hours (FEV1 AUC0-12) [ Time Frame: 12 weeks ]
  2. peak FEV1 [ Time Frame: 12 weeks ]

Secondary Outcome Measures :
  1. Trough FEV1: Trough FEV1 was the FEV1 measured prior to dosing [ Time Frame: 12 weeks ]
  2. Trough and peak FVC and FVC AUC0-12 measured at the same times as FEV1 on each test day [ Time Frame: 12 weeks ]
  3. Individual FEV1 and FVC measurements at each timepoint [ Time Frame: 12 weeks ]
  4. Number (%) of patients with at least one exacerbation of COPD [ Time Frame: 12 weeks ]
  5. time to first exacerbation [ Time Frame: 12 weeks ]
  6. number of exacerbations [ Time Frame: 12 weeks ]
  7. number of exacerbation days [ Time Frame: 12 weeks ]
  8. Average daily occasions of rescue medication [albuterol (salbutamol)] use each week [ Time Frame: 12 weeks ]
  9. All adverse events [ Time Frame: 12 weeks ]
  10. Pulse rate measured in conjunction with spirometry [ Time Frame: 12 weeks ]
  11. Blood pressure (seated) measured in conjunction with spirometry [ Time Frame: 12 weeks ]
