Reduction in AER on Subpopulations at Week 52
Délai: Week 52
Asthma exacerbation is defined as worsening of asthma that leads to any of the following: use of systemic corticosteroids for at least 3 days, an emergency department visit due to asthma that required systemic corticosteroids, and an inpatient hospitalization due to asthma. Reduction in AER was evaluated in pre-specified subpopulations (blood eosinophil count [eosinophilic and non-eosinophilic], T helper cell 2 [Th2] status [high and low], Fraction of exhaled nitric oxide [FENO] [high and low], serum periostin [high and low], current post bronchodilator forced expiratory volume in 1 second [Post-BD FEV1] reversibility- yes, allergic and non-allergic) of asthma. The annual AER was presented as the total number of exacerbations for the treatment group divided by the total duration of person follow-up. Also, the high or low was determined using median value.

Baseline (Week 0 [Day 1]) to Week 52
Change From Baseline in FEV1 on Subpopulations at Week 52
Délai: Baseline and up to Week 52
Forced expiratory volume in one second (FEV1) was evaluated in pre-specified subpopulations of asthma. The data presented in the below table for this outcome measure is for pre-bronchodilator FEV1.
Baseline and up to Week 52
Change From Baseline in Post-bronchodilator (Post-BD) FEV1 and FVC at Week 52

Baseline (Week 0 [Day 1]) to Week 52
Change From Baseline in Overall Symptoms Score on Subpopulations at Week 52
Délai: Baseline and up to Week 52
Asthma symptoms during night time and daytime are recorded by the participant in the asthma daily diary. Overall symptom score is the average of scores of daytime severity, daytime frequency, and nighttime severity symptoms. The daytime frequency and severity items are scored from 0 to 4, where a higher score indicates greater frequency/severity and nighttime severity item is scored from 0 to 4 , where a higher score indicates greater severity. Overall symptom score ranges from 0 to 4, where lower score indicates better asthma symptom while, higher score indicates worse asthma symptom.
Baseline and up to Week 52
Change From Baseline in Asthma Symptoms Measured by Asthma Daily Diary at Week 52
Délai: Baseline (Week 0 [Day 1]) and Week 52
Asthma symptoms during night time and daytime are recorded by the participant in the asthma daily diary. Symptom score values for night time assessment is 0 (no asthma symptom) to 3 (unable to sleep because of asthma) and symptom score values for day time assessment is 0 (no asthma symptom) to 3 (unable to do normal activities due to asthma). Total asthma symptom score is the sum of the daytime and night time score (0 to 6). Lower score (0) is indicating better asthma symptom, while higher score (6) is indicating worse asthma symptom.
Baseline (Week 0 [Day 1]) and Week 52
Change From Baseline in Asthma Symptoms Measured by Asthma Control Questionnaire (ACQ-6) Score at Week 52
Délai: Baseline (Week 0 [Day 1]) and Week 52
The ACQ is a patient-reported questionnaire assessing asthma symptoms (ie, night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing) and daily rescue bronchodilator use and FEV1. The ACQ-6 is a shortened version of the ACQ that omits the FEV1 measurement from the original ACQ score. Questions are weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled).

Délai: Baseline (Week 0 [Day 1]) and Week 52
The AQLQ(S) +12 is a 32-item questionnaire that measures the health-related quality of life experienced by asthma participants.

Change From Baseline in European Quality of Life-5 Dimensions 5 Level Version (EQ-5D-5L) Health State Evaluation at Week 52
Délai: Baseline (Week 0 [Day 1]) and Week 52
European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) is a standardized measure of health status of the participant. The first component is a descriptive system of the respondent's health comprised of the following 5 participant-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive the health state index scores using the United Kingdom (UK) algorithm, with scores ranging from -0.594 to 1. A higher score indicates better health state. The second component is a self-perceived health score which is assessed using a visual analogue scale (VAS) that ranged from 0 to 100, where 0 indicated the worst health you can imagine and 100 indicated the best health you can imagine.
