A Randomized Study, Comparing Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC /VI) Single Inhaler Triple Therapy, Versus Multiple Inhaler Therapy (Budesonide/Formoterol Plus Tiotropium) in Subjects With Chronic Obstructive Pulmonary Disease (COPD)

The primary purpose of this study is to evaluate lung function and health related quality of life (HRQoL) after 84 days of treatment with a single inhaler triple therapy combination of FF/UMEC /VI \[100/62.5/25 microgram (mcg)\] once daily via ELLIPTA® compared with a multiple inhaler combination therapy of Symbicort Metered Dose Inhaler (MDI) (budesonide/formoterol 320/9 mcg) twice daily plus Spiriva HandiHaler (tiotropium 18 mcg) once daily. The study will inform healthcare providers that subjects can be effectively and safely switched to FF/UMEC /VI single inhaler therapy from a multiple inhaler triple therapy regimen of Symbicort MDI and Spiriva Handihaler. Eligible subjects will enter a 4-week run-in period during which they will be administered budesonide/formoterol (320/9 mcg) twice daily plus tiotropium (18 mcg) once daily plus placebo via ELLIPTA. Following the run-in period, subjects will be randomized to receive one of the following study treatments for 84 days: 1) FF/UMEC /VI 100/62.5/25 mcg via ELLIPTA once daily in the morning plus two inhalations of placebo to match budesonide/formoterol via MDI, twice daily plus placebo to match tiotropium via HandiHaler once daily in the morning or 2) Budesonide/formoterol 320/9 mcg via MDI, twice daily plus tiotropium 18 mcg via HandiHaler once daily in the morning plus placebo via ELLIPTA once daily in the morning. Subjects will then enter a one week follow-up period. The total duration for a subject in the study will be approximately 17 weeks.
