Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The number of moderate and severe COPD 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 corticosteroid (oral/IV/IM corticosteroids), and/or use of antibiotics
    • Severe: requiring hospitalisation or resulting in death


Secondary Outcome Measures :
  1. The time to first moderate or severe exacerbation. [ Time Frame: Up to 52 weeks ]
  2. The annual rate of severe exacerbation. [ Time Frame: Up to 52 weeks ]
  3. The time to first severe exacerbation. [ Time Frame: Up to 52 weeks ]
  4. The number of on-treatment severe exacerbations. [ Time Frame: Up to 52 weeks ]
  5. Change from baseline (pre-dose visit 2) in pre-dose FEV1 at week 52. [ Time Frame: At Week 52 ]
  6. Change from baseline in SGRQ total and domain scores at week 52. [ Time Frame: At week 52 ]
  7. SGRQ response (change from baseline SGRQ total score ≤ -4) at week 52. [ Time Frame: At week 52 ]
  8. Change from baseline to last inter-visit period (week 40-52) in E-RS Total and subscale scores [ Time Frame: Up to 52 weeks ]
  9. E-RS response (change from baseline E-RS Total score ≤ -2) at week 52. [ Time Frame: At week 52 ]
  10. 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 ]
  11. Time to study medication discontinuation for any reason. [ Time Frame: Up to 52 weeks ]
  12. 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 ]
