Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

2. Have a diagnosis of COPD (defined as per the COPD guideline)
3. Have a FEV1/FVC ratio \< 0.70 at 15-60 minutes following use of SALTANOL® INHALER
4. Have a FEV1 of \>= 40% to \< 80% of the predicted normal value at 15-60 minutes following use of SALTANOL® INHALER

3. Have a chest X-ray (or CT scan) indicating a diagnosis other than COPD that might interfere with assessments in the study (This must be assessed using last imaging study performed within 6 months prior to Visit 1; or, a chest X-ray must be obtained at Visit 1.)
4. Have chronic respiratory failure
5. Have undergone lung volume reduction and/or lung transplant

11. Have a concurrent serious or uncontrolled disease that might interfere with assessments in the study (including psychiatric disease, unstable liver disease, and heart disease)
12. Have a QTc \> 450 msec (or \> 480 msec in patients with bundle branch block) at Visit 1 (based on average QTc from three consecutive cardiac cycles on ECG)
