Trough Forced Expiratory Volume in 1 Second (FEV1) Following 3 Days of Treatment
FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation, measured through spirometry testing. The trough in FEV1 was defined as the mean of two measurements at 23h 10min and 23h 45min post the Day 3 dose.
Time frame: Day 4
Peak Forced Expiratory Volume in 1 Second (FEV1) on Days 1 and 3
Spirometry was conducted according to internationally accepted standards. Peak FEV1 is the maximum FEV1 recorded in the period between 5 minutes and 4 hours post dose on Days 1 and 3.
Time frame: Days 1 and 3
Time to Peak Forced Expiratory Volume in 1 Second (FEV1) on Days 1 and 3
Spirometry was conducted according to internationally accepted standards. Peak FEV1 is the maximum FEV1 recorded in the period between 5 minutes and 4 hours post dose on Days 1 and 3.
Time frame: Days 1 and 3
Forced Vital Capacity (FVC) at Each Time-point on Day 1, 2, 3 and 4
Spirometry was conducted according to internationally accepted standards. FVC was calculated at each time point up to 4 hours post-dose and at 23 hours 10 min and 23 hours 45 min on Days 1/2 and 3/4.
Time frame: Days 1, 2, 3 and 4
Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From pre-dose to 4 hours post dose on Days 1 and 3
FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5, 15, and 30 minutes; and 1, 2, 3 and 4 hours post-dose. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time.
Time frame: Days 1 and 3

Placebo administered via the EPIC Test Fixture.
Peak Expiratory Flow Rate measured daily each morning and evening.
Peak Expiratory Flow (PEF) was measured every morning and evening from screening until study completion using a peak flow meter, and was recorded in the patient diary.
Time frame: Morning and evening from screening to study completion (up to 86 days)
Forced Expiratory Volume in 1 Second (FEV1)
Spirometry was conducted according to internationally accepted standards. Forced expiratory volume in 1 second (FEV1) is the amount of air that can be exhaled in one second. FEV1 was measured at each time point up to 4 hours on Days 1 and 3 and at 23hours 10 mins and 23 hours 45 mins on Days 2 and 4.
Time frame: Days 1, 2, 3 and 4
Ratio of Forced Expiratory Volume in 1 Second (FEV1) and Forced Vital Capacity (FVC) (FEV1/FVC
Spirometry was conducted according to internationally accepted standards. FEV1/FVC represents the proportion of the total amount of air that is exhaled from the lungs during the first second of forced exhalation. FEV1/FVC was measured at each timepoint up to 4 hours on Days 1 and 3 and 23hours 10mins and 23hours 45 mins on Days 2 and 4.
Time frame: Days 1, 2, 3, 4
Forced expiratory Flow 25-75% (FEF25-75%)
The forced expiratory flow (FEF) 25%-75% measurement describes the amount of air expelled from the lungs during the middle half (25% - 75%) of the forced vital capacity test and is measured using spirometry. FEF 25-75% was measured at each timepoint up to 4 hours on Days 1 and 3 and 23hours 10mins and 23hours 45 mins on Days 2 and 4
Time frame: Days 1, 2, 3, 4
Number of puffs of rescue medication used
Participants maintained a diary to record the daily number of puffs of rescue Short-acting B2 agonist (SABA) used to treat asthma symptoms.
Time frame: Everyday from screening to study completion (up to 86 days)
The number of participants with adverse events used as a measure of Safety and Tolerability
Safety and tolerability of indacaterol administered via the EPIC test fixture and the Concept1 was measured by collecting the following safety data: - number and percentage of adverse events reported by participants for the duration of the study - safety laboratory testing - measurement of vital signs (blood pressure and heart rate) - measurement of ECGs
Time frame: Baseline to study completion (up to 59 days)
AUC (0-24) - area under the serum concentration-time curve
The PK parameter AUC0-24 - area under the serum concentration-time curve - was determined from the serum concentration time profile of indacaterol on Days 1 and 3 from time zero to 24 hours post dose using a non-compartmental method
Time frame: Day 1 and Day 3 (pre-dose, 5, 15, 30 mins, 1, 2, 4, 8, 12, 24hours post dose
Cmax - observed maximum serum concentration following drug administration
The PK parameter Cmax - observed maximum serum concentration following drug administration - was determined from the serum concentration time profile of indacaterol on Days 1 and 3 using a non-compartmental method.
Time frame: Day 1 and Day 3 (pre-dose, 5, 15, 30 mins, 1, 2, 4, 8, 12, 24hours post dose
Tmax - time to reach maximum concentration after drug administration
The PK parameter Tmax - time to reach maximum concentration after drug administration - was determined from the serum concentration time profile of indacaterol on Days 1 and 3 using a non-compartmental method.
Time frame: Day 1 and Day 3 (pre-dose, 5, 15, 30 mins, 1, 2, 4, 8, 12, 24hours post dose
Racc - accumulation ratio of exposure (AUC0-24 and Cmax) on Day 3 relative to Day 1
The PK parameter Racc - accumulation ratio of exposure (AUC0-24 and Cmax) on Day 3 relative to Day 1 - was determined from the serum concentration time profile of indacaterol on Days 1 and 3 using a non-compartmental method.
