Brief summary
This study compared the 14-day bronchodilator efficacy of indacaterol with that of placebo and salmeterol.
Interventions
Indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.
Salmeterol was supplied in the manufacturer's proprietary Diskus inhaler device.
Placebo to indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.

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 salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates. |
