Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Change in eosinophils in bronchial biopsies (first and last visit) and in sputum (5 times during the 12-month treatment period)

Secondary Outcome Measures:
  • Immunopathology and remodeling in biopsies
  • Immunopathology and mediators in induced sputum
  • Severe asthma exacerbations (number of and time to first)
  • Forced expiratory volume in 1 second (FEV1)
  • As-needed use
  • Safety variables, including adverse events and vital signs
  • All variables assessed over the 12-month treatment period
