Primary Outcome Measures:
  • FEV1 area under the curve for the time period of 0 to 12 hours (FEV1 AUC0-12) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • peak FEV1 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Trough FEV1: Trough FEV1 was the FEV1 measured prior to dosing [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Trough and peak FVC and FVC AUC0-12 measured at the same times as FEV1 on each test day [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Individual FEV1 and FVC measurements at each timepoint [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Number (%) of patients with at least one exacerbation of COPD [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • time to first exacerbation [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • number of exacerbations [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • number of exacerbation days [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Average daily occasions of rescue medication [albuterol (salbutamol)] use each week [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • All adverse events [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • Pulse rate measured in conjunction with spirometry [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Blood pressure (seated) measured in conjunction with spirometry [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
