Safety and Efficacy of Indacaterol Once Daily Versus Salmeterol Twice Daily in Chronic Obstructive Pulmonary Disease (COPD)

A 12 Week Treatment, Multi-center, Randomized, Parallel Group, Double Blind, Double Dummy Study to Assess the Superiority of Indacaterol (150 µg o.d.) Via a SDDPI in Patients With Moderate to Severe COPD, Using Salmeterol (50 µg b.i.d.) as an Active Comparator Delivered Via a DISKUS Inhaler

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, \[DISKUS\]).

DRUGPlacebo to indacaterol

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.

Participants by arm

ArmCount
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.

FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5 and 30 minutes; 1, 2, 3, 4, and 8 hours; 11 hours 10 minutes and 11 hours 45 minutes 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 and FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening as covariates.
