Primary Outcome Measures:
  • Trough FEV1 (L) at 28 Weeks on Treatment [ Time Frame: 28 weeks ] [ Designated as safety issue: No ]
    Trough FEV1 (mean FEV1 value of the two highest FEV1 readings measured at 23 and 24 hours after inhalation) at 28 weeks

  • Trough FEV1 (L) at 12 Weeks on Treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Trough FEV1 (mean FEV1 value of the two highest FEV1 readings measured at 23 and 24 hours after inhalation) at 12 weeks

Secondary Outcome Measures:
  • Time to First Moderate or Severe COPD Exacerbation at 52 Weeks on Treatment [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]

    Time to first moderate or severe exacerbation:

    Increase of COPD symptoms during at least 2 consecutive days, treated with antibiotics and/or systemic corticosteroids or an increase in dose of systemic corticosteroids, or leading to hospitalisation.

  • Percentage of Patients Who Achieved at Least a 4-unit Decrease From Baseline in the SGRQ Total Score at 52 Weeks on Treatment [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
    Percentage of patients who achieved a clinically relevant improvement in health-related quality of life at 52 weeks, as measured by at least a 4-unit decrease from baseline in St George's Respiratory Questionnaire (SGRQ) total score
