SECONDARY outcome

Timeframe: Day 14 of each of the three treatment periods

Population: The PK analysis set included all patients with at least one available valid (i.e. not flagged for exclusion) PK concentration measurement, who received any study drug and experienced no major protocol deviations with relevant impact on PK data.

AUC 0-24hours of plasma concentrations of indacaterol maleate and indacaterol acetate at steady state.The area under the concentrations-time curve (AUC0-24) was calculated with the measured data points from the time of administration up to 24 h after administration by the trapezoidal formula. The concentration-time curve is the result of time points of blood sampling and its measured concentration in the blood samplings

The FEV1 percent predicted expresses FEV1 as a percentage of the "predicted values" for participants of similar characteristics (height, age, sex, and sometimes race and weight). A positive change from baseline in FEV1 % predicted indicates improvement in lung function. FEV1 % predicted was assessed at each post dose time point after 14 days

Standardized FEV1 AUC from pre-dose to 4 h post-dose. Evaluated the differences in standardized FEV1 AUC0-4h (L) after 14 days of treatment between indacaterol maleate 150 μg and placebo, and between indacaterol acetate 150 μg and placebo. FEV1 was measured with spirometry conducted according to internationally accepted standards. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time over an entire day (AUC 0-4h)

A Peak Expiratory Flow (PEF) meter was distributed to patients at Visit 1, to be used to measure PEF twice-daily as directed. During the Screening and Treatment Periods, PEF was measured in the morning and evening every day. the morning PEF was performed within 15 minutes after waking, and the evening PEF approximately 12 hours later. The highest of 3 values was recorded as the daily personal best. The personal best was used to calculate the mean morning PEF and mean evening PEF value collected between assessment Visits LS Mean of change from baseline in mean morning PEF is calculated with the ANOVA model using treatment, stratification group, dosing schedule, gender, center grouping, smoking status, and baseline mean morning PEF as covariates
