FEV1 Trough Value (Assay Sensitivity)
Change from baseline in trough (pre-dose) FEV1 at Day 29 was based on 2 pre-dose FEV1 assessments performed 30 minutes apart on Day 29. Baseline was calculated by taking the mean of \[prebronchodilator FEV1 measured at a run-in visit and the mean of 2 predose FEV1 measures taken at Day 1\]. To confirm assay sensitivity, both active treatments (MGR001 and Advair Diskus) had to be significantly superior to placebo.
