Primary Outcome Measures:
  • Morning Peak Expiratory Flow (PEF) [ Time Frame: Baseline to 6 weeks ]
    Change in the Morning PEF from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomisation). No imputation of missing data was performed


Secondary Outcome Measures:
  • Evening Peak Expiratory Flow (PEF) [ Time Frame: Baseline to 6 weeks ]
    Change in the Evening PEF from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomisation). No imputation of missing data was performed

  • Asthma Symptom Score, Night [ Time Frame: Baseline to 6 weeks ]
    Change in the Asthma Symptom Score (Night) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Daily scale:0 = No symptoms; 1 = Mild symptoms; 2 = Moderate symptoms; 3 = Severe symptoms.

  • Asthma Symptom Score, Day [ Time Frame: Baseline to 6 weeks ]
    Change in the Asthma Symptom Score (Day) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Daily scale:0 = No symptoms; 1 = Mild symptoms; 2 = Moderate symptoms; 3 = Severe symptoms.

  • Asthma Symptom Score, Total [ Time Frame: Baseline to 6 weeks ]
    Change in the Asthma Symptom Score (Total) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Daily scale:0 = No symptoms; 1 = Mild symptoms; 2 = Moderate symptoms; 3 = Severe symptoms.

  • Percentage of Nights With Awakenings Due to Asthma [ Time Frame: Baseline and 6 weeks ]
    Change in the Percentage of Nights With Awakenings Due to Asthma from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. The participants answered "Yes" or "No" whether she/he woke up during the night due to asthma.

  • Use of Rescue Medication, Night [ Time Frame: Baseline to 6 weeks ]
    Change in the Use of Rescue Medication (Night) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed

  • Use of Rescue Medication, Day [ Time Frame: Baseline to 6 weeks ]
    Change in the Use of Rescue Medication (Day) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed

  • Use of Rescue Medication, Total [ Time Frame: Baseline to 6 weeks ]
    Change in the Use of Rescue Medication (Total) from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed

  • Percentage of Symptom-free Days [ Time Frame: Baseline to 6 weeks ]
    Change in the Percentage of Symptom-free Days from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Symptom-free Day: no symptoms (asthma symptom score=0) night and day, and no awakenings due to asthma.

  • Percentage of Asthma Control Days [ Time Frame: Baseline to 6 weeks ]
    Change in the Percentage of Symptom Control Days from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Asthma Control Day: no symptoms (asthma symptom score=0) night and day, no awakenings due to asthma, no rescue medication.

  • Percentage of Rescue Free Days [ Time Frame: Baseline to 6 weeks ]
    Change in the Percentage of Rescue Free Days from baseline (calculated as a mean using all available data for the 10 last days of run-in period) to week 6 (calculated as a mean using all available data after randomization, with run-in values as covariate). No imputation of missing data was performed. Rescue-free Day defined as day and night with no use of rescue medication.

  • Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: Baseline to 6 weeks ]
    Change in the FEV1from baseline to week 6 (calculated as a mean using all available data after randomization)
