Keywords
respiratory, dyspnea, breathlessness, COPD, indacaterol, long-acting β2-agonist
Brief summary
This study compared the safety and efficacy of indacaterol 150 µg taken once daily (o.d.) versus salmeterol 50 µg taken twice daily (b.i.d) in patients 40 years old or older with chronic obstructive pulmonary disease.
Interventions
Indacaterol 150 μg was provided in powder-filled capsules with a single-dose dry-powder inhaler (SDDPI).
Salmeterol 50 μg was provided in the manufacturer's proprietary multi-dose dry-powder inhaler (MDDPI, \[DISKUS\]).
Placebo to indacaterol was provided in powder-filled capsules with a single-dose dry-powder inhaler (SDDPI).
Placebo to salmeterol was provided in the manufacturer's proprietary multi-dose dry-powder inhaler (MDDPI, \[DISKUS\]).

Standardized FEV1 AUC was calculated by the trapezoidal rule. The analysis included baseline FEV1 and FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening as covariates. |

| Indacaterol 150 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. | 559 |
