- The number of moderate and severe exacerbations occurring during the planned 52-week treatment period. [ Time Frame: Up to 52 weeks ]
Moderate or severe exacerbation is defined by symptomatic worsening of COPD:
- Moderate : requiring use of systemic corticosteroids (oral/IV/IM corticosteroids), and/or use of antibiotics
- Severe : requiring hospitalisation or resulting in death
- The time to first moderate or severe exacerbation. [ Time Frame: Up to 52 weeks ]
- The annual rate of severe exacerbations. [ Time Frame: Up to 52 weeks ]
- The time to first severe exacerbation. [ Time Frame: Up to 52 weeks ]
- The number of all on-treatment severe exacerbations. [ Time Frame: Up to 52 weeks ]
- The number of all on-treatment exacerbations requiring systemic corticosteroids. [ Time Frame: Up to 52 weeks ]
- Change from baseline (pre-dose Visit 2) in pre-dose FEV1, at week 52. [ Time Frame: At week 52 ]
- Change from baseline in SGRQ total and domain scores at week 52. [ Time Frame: At week 52 ]
- SGRQ response (change from baseline SGRQ total score ≤ -4) at week 52. [ Time Frame: At week 52 ]
- Change from baseline to last inter-visit period (week 40-52) in E-RS Total and subscale scores. [ Time Frame: Up to 52 weeks ]
- E-RS response (change from baseline E-RS Total score ≤ -2) at week 52. [ Time Frame: At week 52 ]
- Change from baseline to last inter-visit period (week 40-52) in the percentage of days without intake of rescue medication and in the average rescue medication use (number of puffs). [ Time Frame: Up to 52 weeks ]
- Time to study medication discontinuation for any reason. [ Time Frame: Up to 52 weeks ]
- Time to moderate or severe exacerbation or study medication discontinuation due to any adverse event, lack of efficacy or death (composite endpoint) and time to study medication discontinuation component. [ Time Frame: Up to 52 weeks ]
- Time to moderate/severe exacerbation or study medication discontinuation due to any class-related AE, lack of efficacy, or death (composite endpoint) and time to study medication discontinuation component. [ Time Frame: Up to 52 weeks ]
