Brief summary

This study assessed the efficacy and safety of indacaterol (150 µg once daily \[od\]) when combined with tiotropium (18 µg od) versus tiotropium (18 µg od) treatment alone in patients with chronic obstructive pulmonary disease (COPD)

Measurements were made at 5 and 30 minutes; and 1, 2, 3, 4, 6, and 8 hours post-dose at the end of the study (Week 12, Day 84). Standardized FEV1 AUC was calculated by the trapezoidal rule. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

Indacaterol 150 μg and Tiotropium 18 μg
Patients inhaled indacaterol 150 μg and tiotropium 18 μg once daily in the morning between 8:00 AM and 11:00 AM for 12 weeks. Indacaterol was delivered blinded via a single dose dry powder inhaler (SDDPI). Tiotropium was delivered open-label via the manufacturer's proprietary inhalation device (HandiHaler®). 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.
