The standardized Area Under the Curve (AUC) for Forced Expiratory Volume in one second (FEV1) post dosing (FEV1 AUC) at week 12 of treatment. Serial lung function measurements are taken at various time points following dosing at week 12 to calculate the AUC.

The full analysis set (FAS): all randomized patients who received at least one dose of trial drug, patients were analyzed according to the treatment they were assigned to at randomization. analyzed participants had values at both baseline and the corresponding time frame, i.e. week 12

Trough Forced Expiratory Volume in one second (FEV1) is the mean of FEV1 at 23h 15min and 23h 45min after the morning dose of the previous day. Pre-dose trough FEV1 is the mean of FEV1 at -45min and -15min before morning dose

However, for a given time frame, analyzed participants had values at both baseline and the corresponding time frame.

The standardized Area Under the Curve (AUC) for Forced Expiratory Volume in one second (FEV1) is assessed for different time spans within the overall serial measurement post dosing (FEV1 AUCs Time Spans), at day 1 and at week 12 of treatment. Serial lung function measurements are taken at various time points post dosing on day 1 and at week 12 to calculate the AUC for these different time spans.

However, for a given time frame, analyzed participants had values at both baseline and the corresponding time frame, i.e. Day 1and Week 12

The health status, as reported by the patients, is assessed using the St. George's Respiratory Questionnaire (SGRQ). The SGRQ is a 50 item scale assessing symptoms, patient activities and impact of the disease. Scores range from 0 to 100 units, with higher scores indicating more limitations. The assessment is based on total score as well as the percentage of patients with clinically significant improvement at week 12 versus day 1. A clinically meaningful improvement (MCID) in SGRQ is defined as a decrease of 4 or more units of the SGRQ scale in the total score, as compared to baseline (change from baseline).

The health status, as reported by the patients, is assessed using the St. George's Respiratory Questionnaire (SGRQ). The assessment is based on total score as well as the percentage of patients with clinically significant improvement at week 12 versus day 1. A clinically significant improvement in SGRQ is defined as less than or equal to -4 change from baseline.

However, for a given time frame, analyzed participants had values at both baseline and the corresponding time frame.

Breathlessness at week 12 is measured using the Transition Dyspnea Index (TDI). On day 1, breathlessness is assessed by the Baseline Dyspnea Index (BDI). Patients are considered to have clinically significant improvement with the TDI score change versus BDI being equal to or greater than 1. TDI focal score is based on three domains: functional impairment, magnitude of task and magnitude of effort. Each domain is scored from -3 (major deterioration) to 3 (major improvement) to give an overall TDI focal score of -9 to 9. Higher numbers indicate a better score.

However, for a given time frame, analyzed participants had values at both baseline and the corresponding time frame, i.e. Week 12

Patients reported symptoms using an electronic diary.The diary has 9 symptom questions each am and each pm. Each question can be answered w/1 of 4 pre-defined answers, with a unit value of 0-3, 0 is least & 3 is most severe symptom.Symptom scores are calculated as the mean of combined daily symptom scores(combined from am & pm)for each patient over 12 weeks. The baseline is calculated from the run-in epoch prior to randomization.The change from baseline is in LS mean daily symptom scores over the 12 weeks. If the mean score over the 12 weeks is lower than the baseline, result is (-).A neg. result indicates an improvement in COPD symptom severity. Patients may have met the min. response requirements for the night scores(am questions),but not for the day scores(pm questions)or vice versa, the # of patients analyzed can vary between both day & night scores. Therefore, the # of patients analyzed for the combined daily symptom score can vary from the #s for individual day & night scores.

Participants from the full analysis set (FAS), who had outcome measure data with applicable fixed effects/covariates according to the analysis model, were analyzed only and included all randomized patients who received at least one dose of study drug.

Patients are reporting symptoms by using an electronic diary. A night with "no nighttime awakening" is defined from diary data as any night where the patient did not wake up due to symptoms. Percentage of no nighttime awakenings from Baseline up to 12 weeks.

Patients are reporting symptoms by using an electronic diary. A day with "no daytime symptoms" is defined from diary data as any day where the patient has recorded in the evening no cough, no wheeze, no production of sputum, and no feeling of breathlessness (other than when running) during the past approximately 12 hours. The percentage of days is calculated by the number of days with no daytime symptoms/total number of days with evaluable data X 100.
