Outcomes
Primary Outcomes
FEV1 Peak (0-3h) Change From Baseline
Time Frame: 10 minutes before drug administration and 30 minutes, 1 hour (h), 2h and 3h after drug administration at baseline and week 12
Change from baseline in peak Forced expiratory volume in 1 second within the first 3 hours post dosing (FEV1 peak (0-3h)) measured at week 12
Weekly Mean Combined Daytime Asthma Symptom Score
Time Frame: Baseline and 12 weeks
Change from baseline in the weekly mean combined daytime asthma symptom score as assessed by the Paediatric Asthma Caregivers Diary (PACD) in the last week of the 12 week treatment period. The PACD is a diary designed to evaluate daily asthma symptoms in children aged 2-5 years. The diary consists of three questions to be answered each morning, when the child wakes up, and seven questions to be answered each evening, right after the child goes to bed for the night. A week was defined as 7 days. The combined daytime score is the average of scores from questions 4 - 7 in the diary which are questions regarding severity of cough, wheezing, trouble breathing and interference with activities, scores for each question range from 0 (best) to 5 (worst). The week 12 weekly mean is the mean of the responses for each day averaged over the 7 days in week 12, so combined daytime asthma symptom scores also range from 0 (best) to 5 (worst). The measured values presented are adjusted means.
