Trial overview
Official title: A randomised, double-blind, double dummy, 3 way cross-over study evaluating the effects of ADOAIR 50/250mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg alone and ADOAIR 50/250mcg alone) in the treatment of Japanese subjects with COPD
Trial description: The purpose of this study is to evaluate the effects on lung function of a combination of ADOAIR 50/250mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg once daily alone and ADOAIR 50/250mcg twice daily alone) in Japanese subjects with COPD. The study will utilize a three-way cross-over design with a 2-week wash-out period between each 4-week consecutive treatment period. The aim is to support the rationale for “triple combination” therapy by demonstrating that treatment with both ADOAIR and tiotropium can potentially produce improved, clinically relevant effects compared with either treatment alone. This study will utilize a range of lung function measures in order to fully assess the benefits of triple therapy. The primary endpoint will be based on airways conductance measured using plethysmography (sGaw measured over 4hours post dose (AUC 0-4hr) on Day 28). Secondary endpoints will include lung function measures based on plethysmography and spirometry. The lung function measures will be supported by measurement of the use of relief salbutamol .

- Had any changes in COPD medication in the 4 weeks prior to Visit 1
Inclusion and exclusion criteria
Inclusion criteria:
- Male or female aged 40
- 80 years inclusive
- Has an established clinical history of COPD (defined as per the GOLD definition)
- A signed and dated written informed consent is obtained from the subject prior to study participation
- The subject has a post-bronchodilator FEV1 of >=30% to =<75% of predicted normal at Visit 1
- The subject has a post-bronchodilator FEV1/ FVC ratio <70% at Visit 1
- The subject achieves a score of 1 on the Modified Medical Research Council (mMRC) Dyspnoea Scale at Visit 1

Ex-smokers are required to have stopped smoking for at least 6 months prior to visit 1. Ex-smokers who stopped smoking less than 6 months ago will be defined as current smokers.
