ListOutcomeTime frameDescription
PrimaryAnnual Asthma Exacerbation Rate in Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma for Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Annual asthma exacerbation rate over the 48-week treatment period among benralizumab and placebo groups
SecondaryChange From Baseline at Week 48 in Pre-bronchodilator FEV1 (L) Value for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Change from baseline at Week 48 in Pre-bronchodilator FEV1 (L)
SecondaryChange From Baseline at Week 48 in Total Asthma Symptom Score for for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48
Daytime and nighttime symptoms are reported using a response scale ranging from 0 to 3 where 0 indicates no asthma symptoms. The total asthma symptom score is the sum of the daytime and nighttime scores and ranges from 0 to 6; a decrease in score indicates symptom improvement.
SecondaryChange From Baseline at Week 48 in Total Asthma Rescue Medication Use for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Change from baseline at week 48 in total rescue medication use (number of puffs/day)
SecondaryChange From Baseline at Week 48 in Morning Peak Expiratory Flow (PEF) for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Change from baseline at week 48 in morning PEF
SecondaryChange From Baseline at Week 48 in Evening Peak Expiratory Flow (PEF) for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Change from baseline at week 48 in evening PEF
Secondary
Change From Baseline at Week 48 in the Proportion of Night Awakening Due to Asthma and Requiring Rescue Medication for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uL
From randomization through Study Week 48Change from baseline at Week 48 in proportion of night awakening due to asthma and requiring rescue medication
SecondaryChange From Baseline at Week 48 in Asthma Control Questionnaire 6 (ACQ-6) for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48ACQ-6 contains one bronchodilator question and 5 symptom questions. Questions are rated from 0 (totally controlled) to 6 (severely uncontrolled). Mean ACQ-6 score is the average of the responses.
SecondaryTime to First Asthma Exacerbation for Patients on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Time to first asthma exacerbation over 48-week treatment period
SecondaryNumber and Percentage of Patients With >=1 Asthma Exacerbations Among Patients Who Were on Medium to High-dose ICS-LABA With Uncontrolled Asthma and Baseline Eosinophils >=300/uLFrom randomization through Study Week 48Number and percentage of patients with at least one exacerbation over 48-week treatment period
