Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Indacaterol 75 μg<br>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. | Drug: Indacaterol 75 μg<br>* Indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.<br>|
| Placebo Comparator: Placebo to indacaterol<br>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. | Drug: Placebo to indacaterol<br>* Placebo to indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose at the End of the Study (Week 12 + 1 Day, Day 85) | FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 10 minutes and 23 hours 45 minutes post-dose at the end of treatment. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of albuterol during screening, and FEV1 pre-dose and 50-70 minutes post-dose of ipratropium during screening as covariates. | 24 hours post-dose at the end of the study (Week 12 + 1 day, Day 85) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Transition Dyspnea Index (TDI) Total Score at the End of the Study (Week 12, Day 84) | An independent (where feasible), trained assessor interviewed the patient and rated the degree of impairment due to dyspnea on a scale from -3 (major deterioration) to 3 (major improvement) on 3 domains (functional impairment, magnitude of task, and magnitude of effort) in comparison with baseline. A total score of the 3 domains ranged from -9 to 9; minus scores indicate deterioration. The analysis included baseline dyspnea index, FEV1 pre-dose and 10-15 minutes post-dose of albuterol during screening, and FEV1 pre-dose and 50-70 minutes post-dose of ipratropium during screening as covariates. | End of the study (Week 12, Day 84) |
