Spirometry is conducted according to the global standard. Trough FEV1 is defined as the average of the 23 hour 10 minute and 23 hour 45 minute post dose FEV1 readings.

Spirometry is conducted according to the global standard. FEV1 is measured at pre-dose and post dose up to 1 hours on Day 1 and Day 28; 24 hours post-dose on Day 29 and 85. In a subset of approximately 60 patients, FEV1 is measured up to 20 hours postdose on Day 28 and Day 84.

Spirometry is conducted according to the global standard. FEV1/FVC is measured at pre-dose and post dose up to 4 hour on Day 1, Day 28, and Day 84, at post dose 12 hour, 23 hour 10 minute and 23 hour 45 minutes on Day 2 and Day 29, and at pre-dose 50 min and 15 min on Day 2, Day 28, and Day 84.

Spirometry is conducted according to the global standard. FEV1 AUC (5 min-4 h), Scheduled (not actual) time points are to be used. The standardized AUC(5 min - 4 h) for FEV1 will be summarized by treatment.

Spirometry is conducted according to the global standard. FEV1 AUC (5 min-4 h), (5 min-24 h) is measured after the first dose on Day 1 and on Day 28 and Day 84 in a subset of approximately 60 patients. Scheduled (not actual) time points are to be used. The interpretation of FEV1 at time 0 is the baseline value at the randomization visit and the latest pre-dose value (-50 min or -15 min) at subsequent visits. The standardized AUC(5 min - 4 h) for FEV1 will be summarized by treatment. The same will be repeated for standardized AUC for FEV1 between 5 min and 24 hours post morning dose.

Participants record the number of puffs of rescue medication taken in the previous 12 hours each morning and evening throughout the 12 week treatment period.

This value represents the percent of days in the study where no rescue medication was needed.

A Total and three component scores are calculated: Symptoms; Activity; Impacts. Each component of the questionnaire is scored separately:The score for each component is calculated separately by dividing the summed weights by the maximum possible weight for that component and expressing the result as a percentage: Score = 100 x Summed weights from all positive items in that component divided by Sum of weights for all items in that component The Total score is calculated in similar way: Score = 100 x Summed weights from all positive items in the questionnaire divided by Sum of weights for all items in the questionnaire Sum of maximum possible weights for each component and Total: Symptoms 566.2 Activity 982.9 Impacts 1652.8 Total (sum of maximum for all three components) 3201.9 The proportion of patients who achieve a clinically important improvement of at least 4 units in the total SGRQ will be analyzed. The higher the score the more symptoms of disease are present.

A TDI focal score of ≥1 is considered to be a clinically important improvement from baseline. Analysis of the proportion of subjects with a clinically important improvement of >=1 point in the TDI focal score, by visit

It consists of eight items, each presented as a semantic 6-point differential scale, providing a total score out of 40. A higher score indicates a worse health status. Scores of 0 - 10, 11 - 20, 21 - 30 and 31 - 40 represent a mild, moderate, severe or very severe clinical impact of COPD upon the patient.

Scoring the MOS Sleep Survey is a two-step process:• All items are scored so that a high score reflects more of the attribute implied by the scale name. Each item is converted to a 0 to 100 possible range so that the lowest and highest possible scores are set at 0 and 100, respectively. In this format, scores represent the achieved percentage of the total possible score. For example, a score of 50 represents 50% of the highest possible score.

• Second, items within each scale are averaged together to create the 7 scale scores. Scales with at least one item answered can be used to generate a scale score. Items that are left blank (missing data) are not taken into account when calculating the scale scores. Scores represent the average for all items in the scale that the respondent answered. An additional measure is based on the average number of hours sleep each night during the past 4 weeks and are described in outcome measure 15.

The sleep quantity subscale,which refers to question 2 of the PRO: On average, how many hours did you sleep each night during the past 4 weeks. More hours of sleep indicate better outcome.

The EXACT is a 14-item electronic questionnaire designed to detect the frequency, severity, and duration of exacerbations in patients with COPD.

Time-to-event variables will be analyzed by the Kaplan-Meier estimates and the stratified Cox proportional hazard model by smoking status and COPD severity. The model will include treatment and country as factors, and FEV1 prior to inhalation and FEV1 15 min post inhalation of salbutamol/albuterol as covariates. The reported measure will detail the percentage of participants that were event free of a specified event.

The model will include treatment and country as factors, and FEV1 prior to inhalation and FEV1 15 min post inhalation of salbutamol/albuterol as covariates. The reported measure will detail the percentage of participants that had an exacerbation up to week 12. Less exacerbations reflect a better outcome.
