Outcomes

Primary Outcomes

Trough Forced Expiratory Volume in 1 Second (FEV1) at Week 12

FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 15 minutes and 23 hours 45 minutes post-dose. The analysis included baseline FEV1 measurement, baseline inhaled corticosteroid use (Yes/No), FEV1 prior to inhalation of short-acting β2 agonist (SABA), and FEV1 45 min post-inhalation of SABA as covariates.

Time frame: Week 12

Secondary Outcomes

Transition Dyspnea Index (TDI) at Week 26

The TDI measured changes in dyspnea from baseline during treatment and included 3 domains: Functional impairment (activities of daily living), magnitude of task (intensity of activity), and magnitude of effort (difficulty breathing). Each domain was rated from -3 to 3 (major deterioration-major improvement). The total score ranged from -9 to 9; minus scores indicate deterioration. The analysis included the same covariates as the primary Outcome Measure.

Time frame: Week 26

Health-related Quality of Life (QoL) Assessed With the St. George Respiratory Questionnaire (SGRQ) at Week 52

The SGRQ contained 51 patient-rated items divided into three components: Symptoms (respiratory symptoms, their frequency, and severity), Activity (activities that cause or are limited by breathlessness), and Impacts (social functioning and psychological disturbances resulting from airway disease). A total score for the 3 components was calculated and ranged from 0 to 100. Higher values indicate greater impairment of QoL. The analysis included the same covariates as the primary Outcome Measure.

Time frame: Week 52

Time to First Moderate or Severe Chronic Obstructive Pulmonary Disease (COPD) Exacerbation During the Study (Baseline to Week 52)

Time to first moderate or severe COPD exacerbation was calculated as the number of days from baseline to the day on which the patient experienced the first moderate or severe COPD exacerbation. A COPD exacerbation was considered to be moderate if treatment with systemic corticosteroids and/or antibiotic was required. A COPD exacerbation was considered to be severe if treatment for moderate severity and hospitalization was required.

Change From Baseline in the Mean Daily Number of Puffs of Rescue Medication Taken During the Study (Baseline to Week 52)

The number of puffs of rescue medication taken in the previous 12 hours was recorded in the Patient Diary in the morning and evening. The mean daily number of puffs of rescue medication taken was calculated by dividing the number of puffs of rescue medication per day over the 52 weeks of the study by the number of days with non-missing rescue medication data. Rescue medication data recorded during the 14 day run-in period was used to calculate the baseline. The analysis included the same covariates as the primary Outcome Measure. A positive change score indicates more puffs taken.

Trough Forced Vital Capacity (FVC) at Day 1, Week 12, Week 26, and Week 52

Trough FVC is defined as the average of the post-dose 23 h 15 min and the 23 h 45 min FVC values. Just prior to FVC measurement, patients performed normal tidal breathing. The patient was given a few breaths warning before being told "At the end of the next normal breath out, take a deep breath all the way in"; they were then verbally encouraged to make a maximal effort before relaxing. The analysis included the same covariates as the primary Outcome Measure.

Number of Moderate or Severe Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) Per Year During the Study (Baseline to Week 52)

The number of moderate or severe exacerbations of COPD per year during the study was calculated by dividing the total number of exacerbations during the study by the total number of years of treatment. A COPD exacerbation was considered to be moderate if treatment with systemic corticosteroids and/or antibiotic was required. A COPD exacerbation was considered to be severe if treatment for moderate severity and hospitalization was required.

Time frame: Baseline to Week 52

Percentage of Patients Who Experienced a Moderate or Severe Chronic Obstructive Pulmonary Disease (COPD) Exacerbation During the Study (Baseline to Week 52)

A COPD exacerbation was considered to be moderate if treatment with systemic corticosteroids and/or antibiotic was required. A COPD exacerbation was considered to be severe if treatment for moderate severity and hospitalization was required.

Time frame: Baseline to Week 52

Percentage of Nights With "no Nighttime Awakenings" During the Study (Baseline to Week 52)

A night with "no nighttime awakenings" was defined as any night where the patient did not wake up due to 1 or more of 6 symptoms (respiratory symptoms, cough, wheeze, amount of sputum, color of sputum, and breathlessness). Symptoms occurring during the previous 12 hours were recorded each morning and evening by the patient in an electronic diary. The percentage of nights with 'no nighttime awakenings' was calculated as the total number of nights with "no nighttime awakenings" over the 52 week treatment period divided by the total number of nights where diary recordings were made.

Time frame: Baseline to Week 52

Percentage of Days With "no Daytime Symptoms" During the Study (Baseline to Week 52)

A day with "no daytime symptoms" was defined as any day where the patient recorded no cough, no wheeze, no production of sputum, no feeling of breathlessness (other than when running), and no puffs of rescue medication during the previous 12 hours in evening entry in the electronic patient diary. The percentage of days with "no daytime symptoms" was calculated as the total number of days with "no daytime symptoms" over the 52 week treatment period divided by the total number of days where diary recordings were made.

Time frame: Baseline to Week 52

Percentage of "Days Able to Perform Usual Daily Activities" During the Study (Baseline to Week 52)

A "day able to perform usual daily activities" was defined as any day where the patient recorded in their electronic diary in the evening that they were not prevented from performing their usual daily activities due to respiratory symptoms during the previous 12 hours. The percentage of "days able to perform usual daily activities" was calculated as the total number of "days able to perform usual daily activities" over the 52 week treatment period divided by the total number of days where diary recordings were made.

Time frame: Baseline to Week 52

Change From Baseline in the Mean Daily Total Symptom Score During the Study (Baseline to Week 52)

The daily total symptom score was defined as the sum of the morning and evening patient self-reported diary assessments of 6 symptoms (respiratory symptoms/impact on daily activities, cough, wheeze, amount of sputum, color of sputum, and breathlessness). Means for baseline (14 day maximum run-in period) and the 52 week treatment period were calculated. Mean scores ranged from 0-18, with a higher score indicating worse symptoms. A negative change score indicated improvement.
