  Description
Placebo-Ind 150 μg-Ind 300 μg-Ind 600 μg-Salmeterol

In treatment period 1: patients received 2 placebo capsules; in treatment period 2: patients received 1 indacaterol (Ind) 150 μg capsule + 1 placebo capsule; in treatment period 3: patients received 1 indacaterol 300 μg capsule + 1 placebo capsule; and in treatment period 4: patients received 2 indacaterol 300 μg capsules. Two inhalation capsules of study drug were inhaled using a single dose dry powder inhaler (SDDPI) in the morning on day 1 of each treatment period at approximately the same time of day +/- 15 minutes. There was a washout period of 14-28 days between each treatment period. In open label treatment period 5: patients received 100 μg salmeterol (50 μg in the morning, 50 μg twelve hours post initial dose) inhaled via Diskus®, an inhalation device, on Day 1.

Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol was available for rescue use throughout the study.

  Description
Entire Study Population

The entire study population included all 4 treatment groups who received indacaterol 150 µg, 300 µg, and 600 µg and placebo via a single dose dry powder inhaler (SDDPI) in the 4 different sequences of the core phase. Two capsules of study medication were inhaled in the morning on Day 1 of each treatment period. Following the core phase patients continued to the Salmeterol open label phase. Salmeterol was inhaled via a Diskus inhalation device 50 µg in the morning and 50 µg 12 hours post initial dose on Day 1. Patients received each treatment only once.

Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol was available for rescue use throughout the study.
