Baseline-adjusted Forced Expiratory Volume in 1 Second (FEV1) Area Under the Curve (AUC 0-6) Over the 12-week Treatment Period
기간: Day 1, Day 8 and Day 85

FEV1 AUC 0-6 is the area under the effect-time curve from time 0 (pre-dose) up to 6 hours post-dose. It represents the weighted average (by the trapezoidal rule) of FEV1 AUC 0-6 measures adjusted for the baseline measure (i.e., change from baseline at each timepoint) recorded on days 1, 8 and 85 of the treatment period. The baseline for each study day was the average of the 2 pre-dose FEV1 measurements on that study day.

FEV1 was measured using spirometry. Spirometry assessments were obtained predose at -30 ± 5, and - 5 minutes, then post dose at 5 ± 2, 15 ± 5, 30 ± 5, 45 ± 5 minutes, and at 1hr ± 5 min, 2hr ± 5 min, 3hr ± 5 min, 4hr ± 5 min, 5hr ± 5 min, and 6hr ± 5 min.

Day 85
Participants With Adverse Events
기간: Day 1 to Day 92
Adverse events (AEs) summarized in this table are those that began or worsened after treatment with study drug (treatment-emergent AEs). An adverse event was defined in the protocol as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily activities. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
Day 1 to Day 92
Physical Examination Findings Shifts From Baseline to Endpoint by Treatment Group
기간: Day 1 (Baseline), Day 85
Physical exam was recorded as normal or abnormal based on physician assessment. Format for results is: Test Baseline/Endpoint HEENT = head, eyes, ears, nose, throat
Day 1 (Baseline), Day 85
Participants With Clinically Significant Vital Sign Assessments
기간: Day 8, Day 85

For both standard and serial vital signs, participants were seated for at least 5 minutes before vital signs were assessed. Heart rate was obtained prior to the blood pressure measurement. Serial heart rate and blood pressure were conducted in the sitting position prior to the spirometry assessment; baseline measures were taken pre-dose at -30 ± 5 and -5 minutes on Day 1. Day 85 serial vital sign measures were taken in the sitting position prior to spirometry assessments pre-dose at -30 ± 5 and -5 minutes, then post-dose at 30 (±5) minutes, 1hr (± 10 min), 2hr (± 10 min), 3hr (± 10 min), 4hr (± 10 min), 5hr (± 10 min) and 6 hr (± 10 min).

Serial heart rate and blood pressure measurements that were elevated to the following criteria were considered clinically significant:

Systolic blood pressure: > 160 beats/minute Diastolic blood pressure: >100 beats/minute Heart rate: >120 beats/minute
