Outcomes
Primary Outcomes
Absolute Change From Baseline in Pre-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 12: ITT Population
Time Frame: Baseline, Week 12
FEV1 was the volume of air exhaled in the first second of a forced expiration as measured by spirometer.
Annualized Rate of Severe Exacerbation Events During The 52-Week Treatment Period: Intent-to-Treat (ITT) Population
Time Frame: Baseline to Week 52
A severe exacerbation was defined as a deterioration of asthma requiring: use of systemic corticosteroids for \>=3 days; or hospitalization or emergency room visit because of asthma, requiring systemic corticosteroids. Annualized event rate was the total number of exacerbations that occurred during the treatment period divided by the total number of participant-years treated.
