Annualized Rate of Severe Exacerbation Events During the 52-Week Treatment Period: Baseline Blood Eosinophils >=300 Cells Per Microliter Population |
A severe asthma exacerbation event was defined as a deterioration of asthma during the 52-week treatment period requiring: use of systemic corticosteroids for >=3 days; and/or hospitalization or emergency room visit because of asthma requiring systemic corticosteroid treatment. Annualized event rate was defined as the total number of severe exacerbation events that occurred during the 52-week treatment period divided by the total number of participant-years followed in the 52-week treatment period. |

ACQ-7-IA had 7 questions, assessed: frequency of nocturnal awakenings, severity of asthma symptoms in the mornings, limitation of daily activities, shortness of breath due to asthma and wheeze, reliever medication use, and FEV1 (% predicted). Participants recalled their previous week asthma and answered 5 symptom questions on 7-point scale ranging from 0 (no impairment) to 6 (maximum impairment). Total score:mean of scores of all 7 questions; ranging from 0 (totally controlled) to 6 (severely uncontrolled), higher score indicated lower asthma control. LS means and SE were derived from MMRM model with change from baseline in ACQ-7-IA values up to Week 52 as response variable and treatment, age, baseline weight group, region, baseline eosinophil level, baseline FeNO level, baseline ICS dose level, visit, treatment by-visit interaction, baseline ACQ-7-IA value and baseline-by-visit interaction as covariates. |

Change From Baseline in Pediatric Asthma Quality of Life (QoL) Questionnaire With Standardized Activities-Interviewer Administered (PAQLQ[S] IA) Scores at Weeks 12, 24, 36, and 52: Type 2 Inflammatory Asthma Phenotype Population |
PAQLQ(S)-IA, a disease-specific, interviewer-administered QoL questionnaire designed to measure functional impairments that are most important to children >=7 years with asthma. The PAQLQ(S)-IA comprises of 23 items in 3 domains: symptoms (10 items), activity limitation (5 items) and emotional function (8 items). Each item was scored on a 7-point likert scale (1=maximal impairment to 7=no impairment). 23 items of questionnaire were averaged to produce 1 overall quality of life score ranging from 1 (severely impaired) to 7 (not impaired at all), higher scores indicated better quality of life. LS means and SE were derived from MMRM model with change from baseline in PAQLQ(S)-IA global score values up to Week 52 as the response variable, and treatment, age, baseline weight group, region, baseline eosinophil level, baseline FeNO level, baseline ICS dose level, visit, treatment by-visit interaction, baseline PAQLQ(S)-IA global score value and baseline-by-visit interaction as covariates. |

Adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and did not necessary have to had a causal relationship with treatment.TEAEs were defined as AEs that developed or worsened in grade or became serious during TEAE period which was defined as the period from the time of first dose of study drug to the end of post-treatment period. A serious adverse events (SAE) was any untoward medical occurrence that at any dose resulted in: death; or life-threatening experience; or required inpatient hospitalization or prolongation of existing hospitalization; or resulted in persistent or significant disability/incapacity; or was a congenital anomaly/birth defect or a medically important event.

ADA response was categorized as: treatment emergent and treatment boosted response. 1) Treatment emergent was defined as an ADA positive response in the assay post first dose, when baseline results were negative or missing. 2) Treatment boosted was defined as: an ADA positive response in the assay post first dose that was greater-than or equal to 4-fold over baseline titer levels, when baseline results were positive. The criteria for positive was defined as "30 to > 10,000", where low titer (< 1,000); moderate (1,000 <= titer <= 10,000) and high titer (> 10,000). |
