Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. 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 [ Time Frame: From Baseline up to Week 8 ]
    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.

  2. Mean Change From Baseline in Daily Morning PEF Averaged Over the 8-week Treatment Period [ Time Frame: From Baseline up to Week 8 ]
    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.

  3. Mean Change From Baseline in the Percentage of Symptom-free 24-hour (hr) Periods During the 8-week Treatment Period [ Time Frame: From Baseline up to Week 8 ]
    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.

  4. Mean Change From Baseline in the Percentage of Rescue Free 24-hour (hr) Periods During the 8-week Treatment Period [ Time Frame: From Baseline up to Week 8 ]
    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.

  5. Number of Participants Who Withdrew Due to Lack of Efficacy During the 8-Week Treatment Period [ Time Frame: From the first dose of study medication up to Week 8/Early Withdrawal ]
    The number of participants whose primary reason for withdrawal was lack of efficacy was analyzed.

  6. Number of Participants With Any On-treatment Adverse Events or Serious Adverse Events Throughout the 8-week Treatment Period [ Time Frame: From the first dose of study medication up to Week 8/Early Withdrawal ]
    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.

  17. Number of Participants With the Indicated Result for the Indicated Urinalysis Parameters Tested by Dipstick at Baseline and Week 8/Early Withdrawal [ Time Frame: 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).

    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.

    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).

  20. 24-hour Urinary Cortisol Excretion at Baseline and Week 8 [ Time Frame: Baseline and Week 8 ]
    A 24-hour urine sample was collected for the measurement of 24-hour urinary cortisol excretion at the following scheduled time points: within 7 days prior to Study Visit 3 (Baseline; Week 0) and Study Visit 8 (Week 8). The Baseline value for 24-hour urinary cortisol was taken from Visit 3.

  21. Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at Week 8 [ Time Frame: Baseline and Week 8 ]
    Change from Baseline was calculated as the Week 8 value minus the Baseline value.

  22. Change From Baseline in Heart Rate at Week 8 [ Time Frame: Baseline and Week 8 ]
    Change from Baseline was calculated as the Week 8 value minus the Baseline value.

  3. Occurrence of a culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear during the run-in period that led to a change in asthma management, or in the opinion of the Investigator is expected to affect the subjects asthma status or the subjects ability to participate in the study.
  4. Asthma exacerbation, defined as any worsening of asthma requiring any treatment other than rescue albuterol/salbutamol or regular inhaled corticosteroid use. This includes requiring the use of systemic corticosteroids and / or emergency room visit or hospitalization or a change in subject's regular inhaled corticosteroid dose.
