What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change From Baseline in Trough (Evening Pre-dose and Pre- Rescue Bronchodilator) FEV1 at Week 8
Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled in one second. Pre-dose and pre-rescue bronchodilator (albuterol/salbutamol) trough FEV1 (the measurement of FEV1 performed at the end of the dosing interval) was measured electronically by spirometry in the evening at the Baseline (BL) through Week 8 clinic visits. The highest of 3 technically acceptable measurements was recorded. The Visit 3 FEV1 assessment was used as the Baseline value. Change from Baseline in trough FEV1 was calculated as the value at Week 8 minus the value at Baseline. The analysis was performed using an Analysis of Covariance (ANCOVA) model with covariates of Baseline trough FEV1, country, sex, age, and treatment group.
Measured: Baseline and Week 8
Secondary outcomes (22)
Mean Change From Baseline in Daily Trough (Pre-dose and Pre-rescue Bronchodilator) Evening Peak Expiratory Flow (PEF) Averaged Over the 8-week Treatment Period
PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Trough PEF is defined as the PEF measurement performed at the end of the dosing interval. PEF was measured by the participants using a hand-held electronic peak flow meter each evening prior to the dose of study medication and any rescue albuterol/salbutamol inhalation aerosol use. The best of three attempts was recorded by the participants in a daily diary. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the value of the averaged daily evening PEF over the 8-week treatment period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of Baseline trough evening PEF, country, sex, age, and treatment group.
Measured: From Baseline up to Week 8
Mean Change From Baseline in Daily Morning PEF Averaged Over the 8-week Treatment Period
PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Trough PEF is defined as the PEF measurement performed at the end of the dosing interval. PEF was measured by the participants 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 attempts was recorded by the participants in a daily diary. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the value of the averaged daily morning PEF over the 8-week treatment period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of Baseline trough morning PEF, country, sex, age, and treatment group.
Measured: From Baseline up to Week 8
Mean Change From Baseline in the Percentage of Symptom-free 24-hour (hr) Periods During the 8-week Treatment Period
Asthma symptoms were recorded in a daily dairy by the participants every day in the morning and evening before taking any rescue or study medication and before PEF measurement. A 24-hour period in which a participant's responses to both the morning and evening assessments indicated no symptoms was considered as symptom-free. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the averaged value during the 8-week Treatment Period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of Baseline, country, sex, age, and treatment group.
Measured: From Baseline up to Week 8
Mean Change From Baseline in the Percentage of Rescue Free 24-hour (hr) Periods During the 8-week Treatment Period
The number of inhalations of rescue albuterol/salbutamol inhalation aerosol used during the day and night was recorded by the participants in a daily diary. A 24-hr period in which a participant's responses to both the morning and evening assessments indicated no use of rescue medication was considered as rescue-free. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the averaged value during the 8-week Treatment Period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of baseline, country, sex, age, and treatment group.
Measured: From Baseline up to Week 8
Number of Participants Who Withdrew Due to Lack of Efficacy During the 8-Week Treatment Period
The number of participants whose primary reason for withdrawal was lack of efficacy was analyzed.
Measured: From the first dose of study medication up to Week 8/Early Withdrawal
Number of Participants With Any On-treatment Adverse Events or Serious Adverse Events Throughout the 8-week Treatment Period
An adverse event (AE) is defined as 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. A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in disability/incapacity; or is a congenital anomaly/birth defect. Medical or scientific judgment should have been exercised in other situations. Refer to the general AE/SAE module for a list of AEs (occurring at a frequency threshold >=3%) and SAEs.
Measured: From the first dose of study medication up to Week 8/Early Withdrawal
Number of Participants With Clinical/Visual Evidence of Oropharyngeal Candidiasis
A detailed oropharyngeal examination for visual evidence of oral candidiasis was performed for the entire Treatment Period.
Measured: From Baseline up to Week 8/Early Withdrawal
Percentage of Basophils, Eosinophils, Lymphocytes, Monocytes, and Total Neutrophils in the Blood at Baseline and Week 8
Blood samples were collected for the measurement of basophils, eosinophils, lymphocytes, monocytes, and total neutrophils at Baseline (BL) and Week 8 (W8). The Baseline value was the measurement taken at screening (Visit 1).
Measured: Baseline and Week 8
Hematocrit at Baseline and Week 8
Blood samples were collected for the measurement of Hematocrit at Baseline (BL) and Week 8 (W8). The Baseline value was the measurement taken at screening (Visit 1).
Measured: Baseline and Week 8
Hemoglobin at Baseline and Week 8
Blood samples were collected for the measurement of hemoglobin at Baseline (BL)and Week 8 (W8). The Baseline value was the measurement taken at screening (Visit 1).

Number of Participants With the Indicated Result for the Indicated Urinalysis Parameters Tested by Dipstick at Baseline and Week 8/Early Withdrawal
Urinalysis parameters included: Urine Occult Blood (UOB), Urine Glucose (UG), Urine Ketones (UK), Urine Protein (UP), and Urine Leukocyte Esterase test for detecting White Blood Cell (UWBC). The dipstick was a strip used to detect the presence or absence of these parameters in the urine sample. The dipstick test gives results in a semi-quantitative manner, and results for urinalysis parameters can be read as negative (Neg), Trace, 1+, 2+, 3+ and 4+, and for UG the result can be read as Neg, Trace, Trace or 1/10 grams per deciliter (G/dL), 1+ or 1/4 G/dL, 3+ or 1 G/dL, indicating proportional concentrations in the urine sample. Data are reported as the number of participants who had neg, Trace, 1+, 2+, 3+ and 4+ levels at Baseline (BL) and Week 8 (W8)/Early Withdrawal (WD). The Baseline value was the measurement taken at screening (Visit 1).
Measured: Baseline and Week 8/Early Withdrawal
Urine Specific Gravity at Baseline and Week 8/Early Withdrawal
Urine samples were collected for the measurement of urine specific gravity by dipstick method at Baseline and at Week 8/Early Withdrawal. The Baseline value was the measurement taken at screening (Visit 1). Specific gravity is a measure of the amount of material dissolved in the urine. Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. Normal urine has a specific gravity between 1.010 and 1.020.
Measured: Urine specific gravity at Baseline and Week 8/Early Withdrawal
Urine pH at Baseline and Week 8/Early Withdrawal
Urine samples were collected for the measurement of urine pH by dipstick method at Baseline and at Week 8/Early Withdrawal. The Baseline value was the measurement taken at screening (Visit 1). Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0).
Measured: Baseline and Week 8/Early Withdrawal

Primary outcome
Mean Change From Baseline in Trough (Evening Pre-dose and Pre- Rescue Bronchodilator) FEV1 at Week 8
Time frame: Baseline and Week 8
Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled in one second. Pre-dose and pre-rescue bronchodilator (albuterol/salbutamol) trough FEV1 (the measurement of FEV1 performed at the end of the dosing interval) was measured electronically by spirometry in the evening at the Baseline (BL) through Week 8 clinic visits. The highest of 3 technically acceptable measurements was recorded. The Visit 3 FEV1 assessment was used as the Baseline value. Change from Baseline in trough FEV1 was calculated as the value at Week 8 minus the value at Baseline. The analysis was performed using an Analysis of Covariance (ANCOVA) model with covariates of Baseline trough FEV1, country, sex, age, and treatment group.
