Outcomes
Primary Outcome Measures
Change From Baseline in Neutrophil Count in Induced Sputum at Week 12
Induced sputum samples were collected at Baseline and at Week 12. The neutrophil count in induced sputum was measured with the use of a cytological specimen of inflammatory cells in the induced sputum. Change from Baseline in neutrophil count was calculated as the Week 12 value minus the Baseline value (percentage of neutrophil of total cells in induced sputum at Week 12 minus the Baseline value).
Secondary Outcome Measures
Change From Baseline in All Inflammatory Cell Count in Induced Sputum at Week 12
Induced sputum samples were collected at Baseline and at Week 12. All inflammatory cells in induced sputum were counted with the use of a cytological specimen of cells in the induced sputum. Change from Baseline in all inflammatory cell count was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in Interferon (INF)-Gamma-positive Cells and Perforin-positive Cells in Sputum at Week 12
INF-gamma-positive cells and perforin-positive cells were not detected in samples collected in this study due to the conditions of the samples and/or antibodies. No re-assays were performed, "no result"/"no data" was entered into the case report forms, and no statistical analysis or data summarization was performed.
Change From Baseline in Interleukin (IL)-8 Levels in Sputum Supernatant at Week 12
Induced sputum samples were collected at Baseline and at Week 12. The levels of IL-8 in the supernatant of an induced sputum sample were measured at the same time using the multiplex assay system. Change from Baseline in IL-8 levels was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in High-sensitivity C-reactive Protein (hsCRP) Levels in Sputum Supernatant at Week 12
Data cannot be reported because hsCRP was under the lower limit of detection in all samples.
Change From Baseline in Myeloperoxidase (MPO) and Pulmonary Surfactant Protein (SP)-D Levels in Sputum Supernatant at Week 12
Induced sputum samples were collected at Baseline and at Week 12. The levels of MPO and SP-D in the supernatant of an induced sputum sample were measured at the same time using the multiplex assay system. Change from Baseline in MPO and SP-D levels was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in IL-6 and IL-8 Levels in Serum at Week 12
Serum samples were collected at Baseline and at Week 12. The levels of IL-6 and IL-8 in serum samples were measured at the same time using the multiplex assay system. Change from Baseline in IL-6 and IL-8 levels was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in hsCRP, SP-D, and Clara Cell Protein 16 (CC 16) Levels in Serum at Week 12
Serum samples were collected at Baseline and at Week 12. The levels of hsCRP, SP-D, and CC16 in serum samples were measured at the same time using the multiplex assay system. Change from Baseline in hsCRP, SP-D, and CC16 was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in Fibrinogen Levels in Serum at Week 12
Per Protocol Amendment 4, the measurement of fibrinogen levels in serum was removed from the analysis plan because fibrinogen levels were found to be too low and too difficult to measure.
Change From Baseline in Forced Expiratory Volume in One Second (FEV1) and Forced Vital Capacity (FVC) at Week 12
FEV1 and FVC are measures of lung function. FEV1 is defined as the maximal amount of air that can be forcefully exhaled in one second. FVC is defined as the amount of air that can be forcibly exhaled from the lungs after taking the deepest breath possible. Respiratory function tests were performed for the measurement of FEV1 and FVC at Baseline and at Week 12. The values were measured at 15 to 60 minutes following the use of a pressurized metered-dose inhaler. Three technically acceptable values were obtained, and the highest value was recorded. Change from Baseline in FEV1 and FVC was calculated as the Week 12 value minus the Baseline value.
Change From Baseline in the COPD Assessment Test (CAT) Question 1 Score at Week 12
Participants completed the CAT questionnaire before undergoing respiratory function tests at Baseline and at Week 12. The CAT questionnaire is an 8-item questionnaire (comprised of Question [Q] 1 to Q8) designed to assess the health status of participants with COPD. In Question 1, participants were asked to rate how much they cough on a scale of 0 to 5: 0, "I never cough"; 5, "I cough all the time." Change from Baseline was calculated as the Week 12 score minus the Baseline score.
Change From Baseline in the COPD Assessment Test (CAT) Question 2 Score at Week 12

Change from Baseline was calculated as the Week 12 score minus the Baseline score.
Change From Baseline in the COPD Assessment Test (CAT) Question 4 Score at Week 12
Participants completed the CAT questionnaire before undergoing respiratory function tests at Baseline and at Week 12. The CAT questionnaire is an 8-item questionnaire (comprised of Question [Q] 1 to Q8) designed to assess the health status of participants with COPD. In Question 4, participants were asked to rate how breathless they feel when walking up a flight of stairs or a hill on a scale of 0 to 5: 0, "When I walk up a hill or one flight of stairs I am not breathless"; 5, "When I walk up a hill or one flight of stairs I am very breathless." Change from Baseline was calculated as the Week 12 score minus the Baseline score.
Change From Baseline in the COPD Assessment Test (CAT) Question 5 Score at Week 12

The CAT questionnaire is an 8-item questionnaire (comprised of Question [Q] 1 to Q8; each question scored from 0 to 5) designed to assess the health status of participants with COPD. The total score is calculated as the sum of the scores from Questions 1 to 8, for a range of possible scores of 0 to 40. A higher total score represents a lower quality of life, and vice versa. Change from Baseline was calculated as the Week 12 score minus the Baseline score.
Number of Participants Who Experienced the Indicated Number of COPD Exacerbations During the Treatment Period
The occurrence of a COPD exacerbation was assessed on each day of evaluation during the treatment period per the defined severity classifications. COPD exacerbations were classified based on severity as a mild exacerbation (exacerbation of COPD symptoms were manageable by the participant, not requiring systemic corticosteroid or antimicrobial therapy), a moderate exacerbation (exacerbation of COPD symptoms required systemic corticosteroid or antimicrobial therapy), or a severe exacerbation (exacerbation of COPD symptoms required hospitalization). The number of participants who experienced 0, 1, 2, and >=3 exacerbation(s) was summarized.

Brief Summary
The study will be conducted in a respiratory specialist institute in Japan, with standardized techniques and data assurance checks to optimize data quality. The licensed dosage and administration of Adoair in Japan will be applied in this study. Each subject will receive treatment options in a randomized blinded fashion. Subjects will be randomized following a 4-week wash-out phase to take either Adoair 50/250mcg twice daily or placebo twice daily for 12 weeks.
Detailed Description
This is a randomised, double-blind, placebo-controlled, two-arm, parallel-group, 12-week-treatment study in Japanese patients with COPD.
At Visit 1, patients confirmed to be fulfilling all the inclusion criteria and not meeting any of the exclusion criteria will start the 4-week run-in period. During the entire study period, including the run-in period, the only drug allowed to use in addition to the study drug will be oxitropium (short-acting anticholinergic drug) as relief medication. At the end of the run-in period (Visit 2), subjects eligible for randomisation will be evenly randomised to one of the following two treatment groups and start the 12-week treatment period.
ADOAIR®250 one inhalation twice daily from the DISKUS inhaler
Placebo one inhalation twice daily from the DISKUS inhaler
Study completers will be defined as subjects who have completed all examinations, assessments, and study procedures in the study period, including the run-in period and the follow-up period. At completion/discontinuation of the treatment period, subjects will be switched to appropriate COPD treatment at the discretion of the investigator (or subinvestigator).
