Study Arms:
- Indacaterol 150 μg (Type: EXPERIMENTAL): Indacaterol 150 μg once daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI). Placebo to Salmeterol delivered twice daily via a proprietary dry powder inhaler in the morning and in the evening.~Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.
- Placebo (Type: PLACEBO_COMPARATOR): Placebo to Indacaterol once daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI). Placebo to Salmeterol delivered twice daily via a proprietary dry powder inhaler in the morning and in the evening.~Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.
- Salmeterol 50 μg (Type: ACTIVE_COMPARATOR): Salmeterol 50 μg twice daily delivered via a proprietary dry powder inhaler in the morning and in the evening. Placebo to Indacaterol daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI).~Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.
