An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs included abnormal clinically significant findings for spirometry, clinical laboratory parameters, standard 12-lead electrocardiograms (ECGs), vital signs and pulse oximetry examinations. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 84 days that were absent before treatment or that worsened relative to pretreatment state. TEAEs included both serious and non-serious TEAEs.

TEAEs included both serious and non-serious TEAEs.
FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. The study baseline is defined as the most recent non-missing measurement (scheduled or unscheduled) collected before the first dose of study drug in the study.
