Dataset from A 12 Week Study to Evaluate the Effect of Fluticasone Furoate (FF, GW685698)/Vilanterol (VI, GW642444) 100/25 mcg Inhalation Powder Delivered Once Daily Via a Novel Dry Powder Inhaler (NDPI) on Arterial Stiffness Compared With Tiotropium Bromide 18 mcg Delivered Once Daily Via a HandiHaler in Subjects With Chronic Obstructive Pulmonary Disease (COPD).

This study is designed to evaluate the effect of fluticasone furoate (FF, GW685698)/vilanterol (VI, GW642444) Inhalation Powder once daily (QD) on arterial stiffness compared with Tiotropium QD over 12 week treatment period in subjects with COPD and aortic pulse wave velocity (aPWV) > 12.0 m/s at Visit 1. Arterial stiffness will be measured as aPWV. This is a comparator, randomised, double-blind, double-dummy, parallel group, multi-centre study. Subjects who meet the eligibility criteria at Screening and meet the randomization criteria at the end of a 2-week Run-In period will enter a 12-week treatment period. There will be an approximate 7-day Follow-up period after the treatment period.
