Group	Intervention	Description
Indacaterol 75 µg (once a day)	Placebo to Indacaterol	Indacaterol 75 µg once a day (qd) inhaled via Concept1, a single dose dry powder inhaler (SDDPI), in the morning and Placebo to Indacaterol inhaled once daily via Concept1 in the evening for 16 days. All patients had to receive daily treatment with inhaled corticosteroid up to the maximum dose per day in a stable regimen for at least 4-weeks prior to screening and remain stable through out the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.
Indacaterol 150 µg (every other day)	Placebo to Indacaterol	Indacaterol 150 µg every other day (qod) inhaled via Concept1, a single dose dry powder inhaler (SDDPI) for a total of 16 days. Indacaterol 150 µg inhaled via Concept1, a SDDPI, in the morning and Placebo to Indacaterol inhaled via Concept1 in the evening on odd days; and Placebo to Indacaterol inhaled via Concept1 in the morning and in the evening on even days. All patients had to receive daily treatment with inhaled corticosteroid up to the maximum dose per day in a stable regimen for at least 4-weeks prior to screening and remain stable through out the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.
Placebo	Placebo to Indacaterol	Placebo to Indacaterol twice daily (bid) inhaled via Concept1, a single dose dry powder inhaler (SDDPI), in the morning and in the evening for 16 days. All patients had to receive daily treatment with inhaled corticosteroid up to the maximum dose per day in a stable regimen for at least 4-weeks prior to screening and remain stable through out the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in the Trough Forced Expiratory Volume in One Second (FEV1) After Two Weeks of Treatment	Baseline to week 2	Spirometry was conducted according to internationally accepted standards. Trough FEV1 values were calculated as the mean of the 23.17 hours and 23.75 hours post morning dose FEV1 measurements. Analysis of covariance model was used with baseline FEV1 as a continuous covariate.
Change From Baseline in the Forced Expiratory Volume in 1 Second Standardized (With Respect to Time) Area Under the Curve (AUC) From 0 to 24 Hours Post Dose (FEV1 AUC 0-24h) After Two Weeks of Treatment	Baseline, 0-24 hours post dose week 2	Spirometry was conducted according to internationally accepted standards. Standardized area under the curve (AUC 0-24 hours) of FEV1 measurements taken at pre-dose to 24 hours post-dose was calculated based on the trapezoidal rule and was adjusted for the area per time unit using the scheduled time of measurements for FEV1. Analysis of covariance model was used with baseline FEV1 as a continuous covariate.
Change From Baseline in the Forced Expiratory Volume in 1 Second Standardized (With Respect to Time) Area Under the Curve (AUC) From 0 to 48 Hours (FEV1 AUC 0-48h) After Two Weeks of Treatment	Baseline, 0 to 48 hours post dose week 2	Spirometry was conducted according to internationally accepted standards. Standardized area under the curve (AUC 0-48 hours) of FEV1 measurements taken at pre-dose to 48 hours post-dose was calculated based on the trapezoidal rule and was adjusted for the area per time unit by using the scheduled time of measurements for FEV1. Analysis of covariance model was used with baseline FEV1 as a continuous covariate.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in the Forced Expiratory Volume in 1 Second Standardized (With Respect to Time) Area Under the Curve (AUC) From 0 to 12 Hours (FEV1 AUC 0-12h) After Two Weeks of Treatment	Baseline, 0 to 12 hours post dose week 2	Spirometry was conducted according to internationally accepted standards. Standardized area under the curve (AUC 0-12 hours) of FEV1 measurements taken at pre-dose to 12 hours post-dose was calculated based on the trapezoidal rule and was adjusted for the area per time unit by using the scheduled time of measurements for FEV1. Analysis of covariance model was used with baseline FEV1 as a continuous covariate.
