| Change From Baseline in Weighted Mean FEV1 Over 0-4 Hours (h) Post-dose at Day 168 | Baseline (BL) to Day 168 | Co-Primary Endpoint: Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled from the lungs in one second. Serial FEV1 measurements were taken electronically by spirometry at BL, weeks 2, 8, 12, and 84 (Day 168). Weighted mean (WM) was calculated using the 0 - 4 h post-dose FEV1 measurements that included the pre-dose (Day 1: 30 minutes \[min\] and 5 min prior to dosing; other serial visits:23 and 24 h after previous morning dose) and post-dose (5, 15, and 30 min and 1, 2, and 4 h) assessments. BL FEV1 is the mean of the two assessments made 30 and 5 min pre-dose at Day 1. WM change from BL was the WM at the visit minus the BL value. Analysis was performed using a repeated measures model with covariates of treatment, smoking status at screening (stratum), BL- mean of the two assessments made 30 and 5 min pre-dose on Day 1, centre grouping, Day, Day by BL and Day by treatment interactions. |
| Change From Baseline in Clinic Visit Trough (Pre-bronchodilator and Pre-dose) FEV1 at Day 169 | Baseline to Day 169 | Co-Primary Endpoint: Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled from the lungs in one second. Trough FEV1 measurements were taken electronically by spirometry on Days 2, 7, 14, 28, 56, 84, 112, 140, 168, and 169. BL was defined as the mean of the assessments made 30 minutes pre-dose and 5 minutes pre-dose on Treatment Day 1.Trough FEV1 was defined as the mean of the FEV1 values obtained 23 and 24 hours after previous morning's dosing. Change from BL was calculated as the average at each visit minus the BL value. Analysis was performed using a repeated measures model with covariates of treatment, smoking status at screening (stratum), BL - mean of the two assessments made 30 minutes pre-dose and immediately pre-dose on Day 1, centre grouping, Day, Day by BL and Day by treatment interactions. |

| Change From Baseline in Chronic Respiratory Disease Questionnaire Self-administered Standardized (CRQ-SAS) Dyspnea Score at Day 168 | Baseline to Day 168 | Considered an 'Other' endpoint by FDA. CRQ-SAS measures 4 domains (mastery, fatigue, emotional function, and dyspnea) of functioning of participants with COPD: mastery (amount of control the participant feels he/she has over COPD symptoms); fatigue (how tired the participant feels); emotional function (how anxious/depressed the participant feels); and dyspnea (how short of breath the participant feels during physical activities). Each domain is measured on a scale of 1-7 (1=maximum impairment; 7=no impairment). Each domain score is calculated separately. Current assessment was done only for dyspnea domain. BL scores are the derived scores for each domain and total at Day 1 pre-dose. Change from BL was calculated as the average at each visit minus the BL value. Analysis performed used a repeated measures model with covariates of treatment, smoking status at screening (stratum), BL (derived scores at Day 1 pre-dose), centre grouping, Day, Day by BL and Day by treatment interactions. |
| Change From Baseline in Peak Post-dose FEV1 (0-4 Hour) on Day 1 | Baseline and Day 1 | Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled from the lungs in one second. BL FEV1 is defined as the mean of the assessments made 30 minutes pre-dose and immediately pre-dose on Day 1. If one of these two assessments was missing then BL was defined as the single pre-dose FEV1 value on Day 1. Peak post-dose FEV1 (0-4 hours) is the maximum post-dose FEV1 recorded over the nominal timepoints of 5, 15 and 30 min, 1, 2 and 4 hours post the Day 1 dose. Change from BL is calculated as the peak post-dose FEV1 (0-4 hour) on Day 1 minus BL FEV1. Analysis performed used an Analysis of Covariance (ANCOVA) model with covariates of treatment, smoking status at screening (stratum), BL - mean of the two assessments made 30 minutes pre-dose and immediately pre-dose on Day 1, and centre grouping. |
| Time to Onset (Increase of 100 Milliliter [mL] From Baseline in 0-4 Hours Post-dose FEV1) on Treatment Day 1 | Baseline and Day 1 | Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled from the lungs in one second. Baseline FEV1 is defined as the mean of the two assessments made 30 minutes pre-dose and immediately pre-dose on Day 1. Time to onset on Treatment Day 1 is defined as a 100 mL increase from Baseline in FEV1. Time to increase of 100 mL from Baseline was calculated over the 5, 15, 30 minutes, and 1, 2, and 4 hours time points. A participant who had at least one post-dose FEV1 on Day 1, but did not achieve a 100 mL or more increase from Baseline at any scheduled time-point at which FEV1 was assessed up to and including 4 hours was censored. |

Trough FEV1 measurements were taken electronically by spirometry on Days 2, 7, 14, 28, 56, 84, 112, 140, 168, and 169. BL was defined as the mean of the assessments made 30 minutes pre-dose and 5 minutes pre-dose on Treatment Day 1.Trough FEV1 was defined as the mean of the FEV1 values obtained 23 and 24 hours after previous morning's dosing. Change from BL was calculated as the average at each visit minus the BL value. Analysis was performed using a repeated measures model with covariates of treatment, smoking status at screening (stratum), BL - mean of the two assessments made 30 minutes pre-dose and immediately pre-dose on Day 1, centre grouping, Day, Day by BL and Day by treatment interactions.

Time to Onset (Increase of 100 Milliliter [mL] From Baseline in 0-4 Hours Post-dose FEV1) on Treatment Day 1
Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcefully exhaled from the lungs in one second. Baseline FEV1 is defined as the mean of the two assessments made 30 minutes pre-dose and immediately pre-dose on Day 1. Time to onset on Treatment Day 1 is defined as a 100 mL increase from Baseline in FEV1. Time to increase of 100 mL from Baseline was calculated over the 5, 15, 30 minutes, and 1, 2, and 4 hours time points. A participant who had at least one post-dose FEV1 on Day 1, but did not achieve a 100 mL or more increase from Baseline at any scheduled time-point at which FEV1 was assessed up to and including 4 hours was censored.
