简要总结
The purpose of the study is to investigate the effect of fluticasone furoate/vilanterol Inhalation Powder on arterial stiffness compared with placebo and vilanterol over a 24-week treatment period in subjects with COPD and aortic pulse wave velocity of 11.0 m/s or above.

结局指标
主要结局
Mean Change From Baseline (BL) in Aortic Pulse Wave Velocity (aPWV) at the End of the 24-week Treatment Period (Day 168)
时间窗: BL to Day 168
PWV is defined as the speed of travel of the pressure pulse along an arterial segment and can be obtained for any arterial segment accessible to palpation. aPWV is measured with tonometers positioned transcutaneously at the base of the common carotid artery and over the femoral artery. PWV increases with arterial stiffness and is defined by the Moens-Korteweg equation: PWV=square root of (Eh/2ρR), where E is Young's modulus of the arterial wall, h is the wall thickness, R is the arterial radius at the end of diastole, and ρ is the blood density. Change from BL was calculated as the Day 168 value minus the BL value. The analysis was performed using a repeated measures model with covariates of treatment, visit, age, gender, smoking history, history of exacerbation strata, geographical region, BL aPWV and interaction terms of BL by visit and treatment by visit.
次要结局
- Change From BL in Clinic Visit Trough (Pre-bronchodilator and Pre-dose) FEV1 at Day 168(BL to Day 168)
- Mean Number of Occasions Rescue Medication [Albuterol (Salbutamol)] Used During a 24-hour Period Averaged Over the Entire 24-week Treatment Period(BL (Week -1), Week 1 to Week 24)
