Primary Outcome Measures:
  • The Percentage of Participants Who Had Experienced Asthma Exacerbation(s) at the End of the Study [ Time Frame: week 52 ] [ Designated as safety issue: No ]
    Asthma exacerbation was defined as deterioration in asthma leading to oral glucocorticosteroid [GCS] treatment, hospitalization, or emergency room [ER] treatment.


Secondary Outcome Measures:
  • Number of Asthma Exacerbations [ Time Frame: up to 52 weeks ] [ Designated as safety issue: No ]
    Asthma exacerbation was defined as deterioration in asthma leading to oral GCS treatment, hospitalization, or ER treatment. Number of asthma exacerbations during 52 weeks treatment was presented here.

  • Morning Peak Expiratory Flow (PEF) [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    The mean value from a 52-week treatment period.

  • Evening PEF [ Time Frame: 2-week run-in period (14 - 18 days before randomization - week 0) and a 52-week treatment period ] [ Designated as safety issue: No ]
    The mean value from a 52-week treatment period.

  • Forced Expiratory Volume in One Second (FEV1) [ Time Frame: 4, 12, 24, 36 and 52 weeks after randomization ] [ Designated as safety issue: No ]
    The mean value for Weeks 4, 12, 24, 36 and 52 was analysed.

  • Use of As-needed Medication [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    The mean value of total daily number of inhalations from the treatment period for use of as-needed medication (daytime, night-time).

  • Asthma Symptom Score [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    The mean value from the treatment period for Total Asthma Symptom Score (total score: 0 is best - no asthma symptoms; 6 is worst).

  • Nights With Awakening(s) Due to Asthma Symptoms [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    The mean value from the treatment period was presented here.

  • The Percentage of Participants Who Had Experienced First Mild Asthma Exacerbations [ Time Frame: up to 52 weeks ] [ Designated as safety issue: No ]
    Mild asthma exacerbation was defined as morning PEF ≥20% below baseline, daily as-needed medication use ≥2 inhalations above baseline, or a night with awakening due to asthma symptoms. The percentage of participants who had experienced mild asthma exacerbation(s) at the end of the study was presented here.

  • Symptom-free Days (no Symptoms and no Awakenings) [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    A symptom-free day was defined as a day without daytime or night-time symptoms and without night-time awakenings due to asthma symptoms. The mean value was presented here.

  • Percentage of As-needed-free Days [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    An as-needed-free day is defined as a night and day with no use of as-needed medication. The mean value from the treatment period was presented here.

  • Percentage of Asthma-control Days (no Asthma Symptoms, no Awakenings, and no As-needed Use) [ Time Frame: 52-week treatment period ] [ Designated as safety issue: No ]
    An asthma-control day was defined as a a night and day with no asthma symptoms, no awakenings due to asthma symptoms, and no as-needed medication use. The mean value from the treatment period was presented here.

  • Asthma Control Questionnaire (ACQ) [ Time Frame: 4, 12, 24, 36 and 52 weeks after randomization ] [ Designated as safety issue: No ]
    The ACQ developed by Juniper and colleagues (Juniper et al 1999) was used without the FEV1 and Beta 2-agonist questions. The Asthma Control Questionnaire has 5 questions that are assessed on a 7-point scale from 0 to 6 where 0 represents good control and 6 represents poor control. The overall score is the mean of the five responses. At least 4 out of the 5 questions must have been answered to provide a value. The mean of the overall score for Weeks 4 to 52 was presented here.
