  1. Data are mean (SD) unless otherwise stated
  2. *Age is derived using the date of the pre-screening visit. Only year of birth is collected. Day and month of birth are imputed as 30 June. Calculated based on age and duration of asthma at pre-screening. Baseline value was defined as score recorded at the Randomisation visit (Visit 2/Day 1).
  3. §ACQ-6 score 0.75 to <1.5: partially controlled; ACQ-6 score ≥1.5: inadequately controlled. ±Baseline value was defined as the mean over the last 14 days during the run-in period prior to study treatment start date (Randomisation).
