Outcome Measures
Primary Outcome Measures
- Proportion of subjects exhibiting no Airflow Obstruction on average over 26 weeks of treatment in the study sub-population with Airflow Obstruction status at screening [Over 26 weeks of treatment]
Proportion of subjects exhibiting on average Airflow Obstruction negative (AO-) status over 26 weeks of treatment in the study sub-population with Airflow Obstruction positive (AO+) status at screening. A subject is defined as AO+ at screening if post-bronchodilator (salbutamol) FEV1/FVC ratio is < 0.7. A subject is defined as AO- during the treatment period if the mean of their 3 hour post-dose FEV1/FVC ratio collected during the treatment period is ≥ 0.7
Secondary Outcome Measures
- Change from baseline in pre-dose FEV1 at Week 26 [Over 26 weeks of treatment]
