The ACT is a validated self-administered questionnaire utilizing 5 questions to assess asthma control during the past 4 weeks on a 5-point categorical scale (1 to 5). By answering all 5 questions, participants with asthma obtained an ACT score ranging between 5 and 25. Higher scores indicated better control of asthma. An ACT score of <=15 showed poorly controlled asthma; 16 to 19 showed partly controlled asthma and >=20 showed well controlled asthma. The total score was calculated as the sum of the scores from all 5 questions. The primary efficacy analysis (PEA) Population is defined as all Intent-to-Treat (ITT) participants (that is, all participants who were randomized and received at least one prescription of study medication) who have an ACT total score of <20 at Baseline (Day 0). The percentage of responders that is participants with an ACT total score >=20 or an increase from Baseline of >=3 has been presented

A secondary care contact is defined as an inpatient admission or a specialist outpatient visit or an A&E contact. A participant with an A&E contact and subsequent inpatient admission was considered to have had two healthcare contacts. The inpatient admissions recorded at two hospitals on the same day, were counted as a single (inpatient admission) secondary care contact. In the situation where inpatient admission periods overlapped (example, a new inpatient admission was recorded within the dates of an existing inpatient admission period), it was counted as a single (inpatient admission) healthcare contact with start date defined as the earliest inpatient admission date for either of the overlapping admissions and end date defined as the latest discharge date for either of the overlapping admissions. The least square mean annual rate of all on-treatment secondary care contacts along with 95% confidence interval has been summarized.

ITT Population

A severe asthma exacerbation is defined as deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) or antibiotics, and inpatient hospitalization, or emergency department visit due to asthma that required systemic corticosteroids or antibiotics. The date of a severe asthma exacerbation was defined as the exacerbation onset date. Participants who completed the study without a severe asthma exacerbation were censored. Time to first severe asthma exacerbation was measured from the date of randomization (that is, study treatment start date) to the onset date of first severe asthma exacerbation, or study treatment stop date for participants who completed the study without any severe asthma exacerbations (censored). Analyses of time to first severe asthma exacerbation was censored at Day 364. The number of participants with severe asthma exacerbation has been presented.

ITT Population

Salbutamol was prescribed as a rescue medication to be used as and when necessary throughout the study. The number of salbutamol inhalers used by each participant during the study was calculated based on the total number of inhalers (adjusted to an equivalence of 200 metered actuations) prescribed. Number of salbutamol inhalers prescribed during the study was derived taking the participants time on study medication into account so it corresponds to 12 months on treatment. The least square mean number of salbutamol inhalers prescribed per participant during the study has been presented. Only participants exposed to study drug for at least 30 days were included in the analysis.

ITT Population

Initial therapy is defined as the treatment that the participant was prescribed at randomization. Modification of initial therapy included any change in brand, dose or frequency of inhaler, that is, stepping up in class, dose or frequency, stepping down in class, dose or frequency, switching to another brand of inhaler, switching treatment arm or withdrawal from the study. Time to modification of initial therapy was measured from the date of randomization (that is, exposure start date) to the date of modification of initial therapy or date of treatment termination for participants who completed the study without modifiying initial therapy (censored). The number of participants with modification of initial therapy has been presented.

ITT Population

The AQLQ(S) contained 32 items under the following four domains: activity limitation (11 items), symptoms (12 items), emotional function (5 items) and environmental stimuli (4 items). The response format consisted of a seven-point scale where a value of 1 indicated "total impairment" and a value of 7 indicated "no impairment". The total AQLQ(S) score is the mean of all 32 items in the questionnaire and each individual domain score was calculated as the mean of the items within that domain. Hence, the total and domain scores were each defined on a range from 1 to 7 with higher scores indicating a higher quality of life. Baseline value is the value at Day 0 assessment. Change from Baseline is post dose visit value minus Baseline. The percentage of responders that is, participants with an increase from Baseline of >=0.5 in AQLQ(S) total score has been presented. Only those participants available at the specified time point was analyzed.

A serious advent event (SAE) of pneumonia was defined as any SAE in the adverse event special interest (AESI) group of "pneumonia". The incidence of the SAEs of pneumonia for each treatment group is defined as the percentage of participants in that group who have experienced at least one SAE of pneumonia from start date of study treatment to the stop date of exposure + 28 days or date of study discontinuation, whichever is earliest. The percentage of participants with SAE of pneumonia has been presented.

ITT Population

An SAE of pneumonia was defined as any SAE in the AESI group of "pneumonia". The date of an event for an SAE of pneumonia was the AE onset date. Participants who do not have an SAE of pneumonia during the first 364 days of the treatment period (start date of exposure to min [end date of exposure + 28 days, date of study discontinuation, start date of exposure + 363]) were censored. Time to first SAE of pneumonia was measured from the date of randomization (that is, study treatment start date) to the onset date of first SAE of pneumonia. The number of participants with first on-treatment SAE of pneumonia has been presented.
