Brief summary

This study was conducted to provide detailed information on the efficacy of indacaterol in terms of its effect on spirometry assessed forced expiratory volume in 1 second (FEV1) over a 24 hour time period.

Interventions

Indacaterol 300 μg was provided in powder filled capsules with a single-dose dry-powder inhaler (SDDPI).

DRUGPlacebo to indacaterol

Placebo to indacaterol was provided in powder filled capsules with a single-dose dry-powder inhaler (SDDPI).

Salmeterol 50 μg was provided in powder filled capsules with a multi-dose dry-powder inhaler (MDDPI).

Entire Study Population
The entire study population included all 6 treatment groups who received indacaterol 300 µg once daily, placebo to indacaterol once daily, and salmeterol 50 µg twice daily via a single-dose (indacaterol and placebo to indacaterol) or multi-dose (salmeterol) dry-powder inhaler in 6 different sequences. Patients received each treatment for 14 days with a 14 day washout between each treatment period. Indacaterol and placebo to indacaterol were administered double-blind; salmeterol was administered open-label. 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. The analysis included baseline FEV1, defined as the average of the FEV1 values measured at 50 and 15 minutes prior to the first study drug administration in that period, as a covariate.

Time frame: 2 hours post-dose at the end of each treatment period (Day 14)

Population: Modified intent-to-treat (modified ITT) population: All randomized patients who received at least 1 dose of study drug.
