Primary Outcome Measures
NameTimeMethod
Proportion of Participants Who Experience Worsening of Asthma by Week 24up to Week 24

Proportion of participants who experience worsening of asthma by Week 24 as defined by at least 1 of the following:

* On 2 consecutive days, morning (AM) peak expiratory flow (PEF) ≤ 75% of mean AM PEF measured over the last 7 days of the Run-in

* Forced expiratory volume in 1 second (FEV1) \< 80% of baseline

* Increase in rescue medication use of ≥ 6 puffs/day on 2 consecutive days compared to mean use over the last 7 days of the Run-in

* Increase in Asthma Control Questionnaire 5 (ACQ-5; see Outcome Measure 2 for description) score of ≥ 0.5 compared to baseline

* The occurrence of a severe asthma exacerbation (asthma attack) defined as deterioration of asthma that leads to the use of systemic corticosteroids for at least 3 days, hospitalization, or an Emergency Department visit.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline to Week 24 in Morning Peak Expiratory Flow (AM PEF)Baseline, Week 24

AM PEF was measured by participants using an electronic diary.

Change From Baseline to Week 24 in Asthma Control Questionnaire - 5 (ACQ-5) ScoreBaseline, Week 24

The ACQ-5 is a 5-item questionnaire which has been developed as a measure of the participant's asthma control that can be quickly and easily completed. The questions are designed to be self-completed by the participant. The 5 questions enquire about the frequency and/or severity of symptoms in the prior week (nocturnal awakening, activity limitation, shortness of breath, wheeze). The response options for each of these questions consists of a zero (no impairment/limitation) to 6 (total impairment/limitation) scale.

Annualized Rate of Severe Asthma Exacerbationsup to Week 24

A severe asthma exacerbation is defined as deterioration of asthma that leads to the use of systemic corticosteroids for at least 3 days, hospitalization, or an Emergency Department visit.

Change From Baseline to Week 24 in Pre-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1)Baseline, Week 24

Pre-albuterol/salbutamol morning FEV1 was measured using electronic spirometry.

Time to First Asthma Worseningup to Week 24

Time to first asthma worsening is defined as the time from the date of the first dose of study treatment to the first date that any of the components of asthma worsening endpoint is met. See Outcome Measure 1 for the definition of asthma worsening.

Change From Baseline to Week 24 in Post-Bronchodilator FEV1Baseline, Week 24

Post-albuterol/salbutamol morning FEV1 was measured using electronic spirometry.

Percentage of Participants With a Treatment-Emergent Adverse Event (AE)From first dose of study treatment through Week 28

An adverse event (AE) is any untoward medical occurrence in a participant, whether or not considered related to study treatment. Abnormal laboratory test results or other safety assessments, including those that worsened from baseline, that were considered clinically significant in the medical and scientific judgment of the investigator were to be reported as AEs.
