Study Arms:
- Indacaterol 75 μg (Type: EXPERIMENTAL): Patients inhaled indacaterol 75 μg once daily in the morning between 8:00 AM and 11:00 AM via a single-dose dry-powder inhaler (SDDPI) for 12 weeks. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
- Placebo to indacaterol (Type: PLACEBO_COMPARATOR): Patients inhaled placebo to indacaterol once daily in the morning between 8:00 AM and 11:00 AM via a single-dose dry-powder inhaler (SDDPI) for 12 weeks. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
