Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Indacaterol 150 µg
Salmeterol 50 µg
Patients inhaled indacaterol 150 μg once daily in the morning between 8:00 and 11:00 AM via a single-dose dry-powder inhaler (SDDPI) for 12 weeks. Patients also inhaled placebo to salmeterol twice daily, once in the morning between 8:00 and 11:00 AM and once in the evening between 8:00 and 11:00 PM via the manufacturer's proprietary multi-dose dry-powder inhaler (MDDPI, [DISKUS]) 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.
