结局指标
主要结局
Forced Expiratory Volume in 1 Second (FEV1) - Post Dose
时间窗: 60 minutes post-dose in clinic visits at baseline, and week 0, 3, 7, 12 and Trt Avg
Descriptive statistics for post-dose FEV1 (L) by visit; Baseline defined as the last pre-dose value prior to 1st dose of randomized therapy. Trt Avg = Mean of all available valid values after randomization.
Forced Expiratory Volume in 1 Second (FEV1) - Pre Dose
时间窗: Pre AM dose in clinic visits at baseline, and week 3, 7, 12 and Trt Avg
Descriptive statistics for predose FEV1(L) by visit; Baseline defined as the last pre-dose value prior to 1st dose of randomized therapy. Trt Avg = Mean of all available valid values after randomization.
