结局指标
主要结局
Change From Period Baseline in FEV1 (L) AUC(0-24h)
时间窗: Day 1 (24 hours)
Forced Expiratory Volume in 1 second (FEV1) is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. FEV1 will be measured pre-dose and over a 24 hours post-dose period.
次要结局
- Change From Period Baseline in FEV1 (L) AUC(0-12h) and FEV1 (L) AUC(12- 24h)(Day 1 (12 hours))
- Change From Period Baseline in Peak FEV1 (L)(Day 1 (24 hours))
- Change From Period Baseline in Trough FEV1 (L)(Day 1 (24 hours))
- Change From Period Baseline in FVC (L) AUC (0-24h)(Day 1 (24 hours))
