Primary

MeasureTime frameDescription
Change in Asthma Control Questionnaire (ACQ(5)) Score From Baseline at a Regional LevelBaseline and 12 weeksParticipants' levels of asthma control were scored on a 7-point Likert scale from 0 to 6, whereby 0 represents good control and 6 represents poor control of asthma. The regional mean change of overall ACQ(5) score were calculated as change from baseline (Week 0) to the average during the treatment period (mean of scores at Week 4, Week 8, Week 12).
