Clinical Trial Outcome Measures

Primary Measures

  • Change in induced sputum differential neutrophil count from baseline to Week 12
    • Time Frame: 12 weeks
  • Number of Treatment Emergent Adverse Events (TEAEs) in each treatment group leading to treatment discontinuation.
    • Time Frame: 12 Weeks

Secondary Measures

  • Change in induced sputum neutrophil differential count from baseline
    • Time Frame: 14 weeks
  • Change in St Georges Respiratory Questionnaire (SGRQ) from baseline
    • Time Frame: 14 weeks
    • Questionnaire designed to measure impact of COPD on overall health, daily life and perceived well-being. Scores range from 0 -100 with higher scores indicating more limitations.
