Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second using a standardized calibrated spirometer. Weighted mean FEV1 was derived using the post-dose assessments (after 30 minutes and 1, 2, 3, 4 hours) with their actual times and using the pre-dose assessment as the 0 hour measurement.

ITT population (5-17 years old) included all randomized participants who received at least one dose of study treatment. Only those participants with data available at the specified time point have been analyzed.

PEF was defined as the maximum speed of expiration of a participant. PEF was measured using a hand-held electronic peak flow meter each morning prior to the dose of study medication and any rescue albuterol/salbutamol inhalation aerosol use. The best of three measurements were recorded in the electronic patient diary. The mean morning PEF was calculated for each participant as an averaged mean over weeks 1-12 of the treatment period. Baseline was defined as the average of measurements with a non-missing value from Day -6 to Day 1 of pre-dose.

ITT population (5-11 years old) was a subset of the ITT (5-17 years old) population for participants 11 years old and younger at screening (Visit 1). Only those participants with data available at specified time points have been analyzed.

The number of inhalations of rescue albuterol/salbutamol aerosol used during the day and night were recorded in a daily electronic diary. Percentages of rescue-free 24-hour periods was calculated based on the number of 24-hour periods on which a participant recorded no use of albuterol/salbutamol divided by the length of the time period being assessed (with non-missing values of rescue medication recorded, respectively). A 24-hour period in which the response of participants to both the morning and evening assessments indicated no use of rescue medication was considered as rescue free. Baseline was calculated from the evening (Day -7 to Day -1) and morning (Day -6 to Day 1) measurements. Change from Baseline was calculated as the averaged value during the 12-week treatment period minus the Baseline value.

The symptom-free days were recorded in a daily electronic diary every day in the morning and evening before taking any rescue or study medication and before the PEF measurement. Percentages of symptom-free 24-hour periods was calculated based on the number of 24-hour periods on which a participant recorded no symptoms divided by the length of the time period being assessed (with non-missing values of rescue medication recorded, respectively). A 24-hour period in which the response of participants to both the morning and evening assessments indicated no symptoms was considered as symptom free.

Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second. Morning FEV1 was measured using the pre-dose serial spirometry assessment at the Week 12. Baseline was defined as the pre-dose assessment with a non missing value on Visit 2 (Day -5).

Asthma control as measured by improvements in ACQ-5, a five-item questionnaire with response options for each question rated from 0 to 6 scale. A score of 0 indicates well controlled asthma and a score of 6 indicates extremely poorly controlled asthma. Individual questions (concerning nocturnal awakening, waking in the morning, activity limitation, shortness of breath and wheeze) are equally weighted and the ACQ-5 score is calculated as the mean of these 5 item responses. A lower mean score indicates greater asthma control and higher mean score indicates lesser asthma control. Baseline was defined as the pre-dose assessment with a non-missing value on Visit 3 (Day 1).

An AE is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect and important medical events may jeopardize the participant or may require medical or surgical intervention/SOC to prevent one of the other outcomes mentioned before.
