  • Data are presented as mean±SD unless otherwise specified.

  • *Duration of asthma was calculated from the start date of asthma recorded on the eCRF until the date of screening.

  • †The baseline ACQ-7 score was reported at screening, or if missing, at the last visit from run-in.

  • ‡FEV1 reversibility was calculated as increase of FEV1 value after inhalation of bronchodilator (400 µg salbutamol/360 µg albuterol, or equivalent dose) relative to FEV1 value before inhalation of bronchodilator.

  • §The summary of baseline medication is based on randomised set population included in the PALLADIUM and IRIDIUM studies (high-dose MF/IND, n=1063; medium-dose MF/IND, n=1056; high-dose FLU/SAL, n=1064). All other parameters included are based on full analysis set from both the studies.

  • ACQ, Asthma Control Questionnaire; FEV1, forced expiratory volume in 1 s; FLU/SAL, fluticasone propionate/salmeterol xinafoate; ICS, inhaled corticosteroid; LABA, long-acting β2-agonist; MF/IND, mometasone furoate/indacaterol acetate; n, number of patients.
