Primary Outcome Measures:
  • Percentage of Asthma-control Days Over the 6-month Treatment Period [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    An asthma-control day, computed from daily diaries, was any day with no unscheduled visit for asthma care, no use of > than 2 puffs of β-agonist, no use of other asthma rescue medication, and no nocturnal awakening. The percentage of asthma-control days was the number of days with asthma-control divided by the total number of days with non-missing values for this endpoint. The patient diary had questions concerning daytime and nighttime symptoms, morning (AM) and evening (PM) peak expiratory flow rate (PEFR), β-agonist use, asthma attacks and smoking activity.


Secondary Outcome Measures:
  • Change From Baseline in Mean Daytime Symptom Score Over a 6-month Treatment Period [ Time Frame: Baseline and 6 months ] [ Designated as safety issue: No ]
    4 daytime symptoms were evaluated daily on a 7-point scale from 0 (best)- 6 (worst). The on-treatment daytime symptom score was computed by averaging over Period II the mean of the 4 daily symptom scores recorded daily in the diary while the baseline daytime symptom score was obtained by averaging the mean of the 4 daily symptom scores across the daily diary entries of the Baseline period (Period I). The change from baseline in mean daytime symptom score is computed as the difference between the mean on-treatment daytime symptom score & the mean baseline daytime symptom score.

  • Change From Baseline in Average Morning (AM) PEFR (Peak Expiratory Flow Rate) Over a 6-month Treatment Period [ Time Frame: Baseline and 6 months ] [ Designated as safety issue: No ]
    PEFR measurements were performed daily, in the morning before using any medication. The on-treatment AM PEFR was computed by averaging over Period II (treatment period) the AM PEFR recorded daily in the diary, while the baseline AM PEFR was obtained by averaging the AM PEFR across the daily diary entries of the Baseline Period or Period I (placebo run-in period). The change from baseline in average AM PEFR is computed as the difference between mean on-treatment AM PEFR and mean baseline AM PEFR.
