Brief summary
This study compared the effects of a single dose of indacaterol with that of a single dose of tiotropium on inspiratory capacity.
Interventions
Indacaterol was supplied in powder filled capsules together with a single dose dry powder inhaler (SDDPI) device.
Tiotropium was supplied in powder filled capsules together with a single dose dry powder inhaler (SDDPI) device.
Placebo (matching indacaterol) was supplied in powder filled capsules together with a single dose dry powder inhaler (SDDPI) device.

Outcome results
Peak Inspiratory Capacity Assessed With Spirometry in the 4 Hours After Treatment
During the 4 hours following inhalation of the study treatment, inspiratory capacity (IC) was measured with spirometry conducted according to internationally accepted standards. IC was measured 3 times each at 30, 60, 120, 180, and 240 minutes post-dose and the highest value was reported in liters.
Time frame: 4 hour period following inhalation of study treatment
Population: Per protocol population: All randomized patients who received all the study drugs and had at least 1 post-dose inspiratory capacity measurement within 4 hours after inhalation in each treatment period and who were compliant with the protocol and without any major deviation likely to affect the analysis of pulmonary function measurements.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Indacaterol 150 μg | Peak Inspiratory Capacity Assessed With Spirometry in the 4 Hours After Treatment | 2.705 Liters | Standard Deviation 0.676 |
| Tiotropium 18 μg | Peak Inspiratory Capacity Assessed With Spirometry in the 4 Hours After Treatment | 2.630 Liters | Standard Deviation 0.601 |
| Placebo | Peak Inspiratory Capacity Assessed With Spirometry in the 4 Hours After Treatment | 2.557 Liters | Standard Deviation 0.561 |
Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) in the 4 Hours After Treatment
FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made 30, 60, 120, 180, and 240 minutes post-dose. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time.
Time frame: 4 hour period following inhalation of study treatment
Population: Intent-to-treat population: All randomized patients who received all the study drugs and had at least 1 post-dose inspiratory capacity measurement within 4 hours after inhalation in each treatment period.

Force Vital Capacity (FVC) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) in the 4 Hours After Treatment
FVC was measured with spirometry conducted according to internationally accepted standards. Measurements were made 30, 60, 120, 180, and 240 minutes post-dose. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time.
