Brief summary

Part A: Incidence of AE, SAE (including death), withdrawals due to AE Part A: Change from baseline in safety assessments (ECG, vital signs, spirometry, clinical laboratory results and physical examination) Part B: Change in ppFEV1 from baseline to Day 28 (for either Treatment Period 1 or Treatment Period 2), compared to placebo

Detailed description

Part A: Derived PK parameters in plasma and urine for ETD001 after repeat inhaled dose administration, Relative change in ppFEV1 from baseline to D28, compared to placebo. Absolute change in other lung function endpoints including FVC, FEV1/FVC ratio and FEF25-75 from baseline to D28, compared to placebo.Incidence of AE, SAE (including death), withdrawals due to AE.Change in safety assessments from baseline to D28, compared to placebo.Change in CFQ-R (respiratory domain) from baseline to D28, compared to placebo. Population PK characteristics and model generated individual PK Parameters
