Study Endpoints
Primary Endpoints
Rate of Clinically Significant Exacerbations of Asthma
Up to Week 52

Clinically significant exacerbation is defined as worsening of asthma which requires use of systemic corticosteroids and/or hospitalizations and/or Emergency Department (ED) visits. Analysis of the number of exacerbations was performed using a negative binomial model with covariates of treatment group, baseline maintenance Oral Corticosteroids (OCS) therapy (OCS vs. no OCS), region, exacerbations in the year prior to the study (as an ordinal variable) and baseline % predicted Forced Expiratory Volume in 1 second (FEV1), and with logarithm of time on treatment as an offset variable.

Secondary Endpoints
Percent Probability of First Clinically Significant Exacerbations at Week 16, Week 32, and Week 52
