A 6-month, Open Label, Randomised, Efficacy Study to Evaluate Fluticasone Furoate (FF, GW685698)/Vilanterol (VI, GW642444) Inhalation Powder Delivered Once Daily Via the Dry Powder Inhaler ELLIPTA™ Compared With Usual ICS/LABA Maintenance Therapy Delivered by Dry Powder Inhaler in Subjects With Persistent Asthma

Detailed Summary

The combination of FF, an ICS and VI, an orally inhaled LABA has been developed as a once-daily combination therapy for the long-term maintenance treatment of asthma in adults and children \>=12 years of age. Pivotal phase III studies have demonstrated the safety and efficacy of FF/VI in asthma. However, it is increasingly acknowledged that randomised clinical trials tend to be highly controlled and enrol a more highly selected subject population than is expected to be prescribed the medication post-approval. There is a need for data in a more representative population in close to a 'real life' conditions, where physicians have the ability to choose the best treatment in their view for any individual subject and adapt treatments to subjects' characteristics and response. This multi-center, open-label, randomized, parallel group study will evaluate the efficacy and safety of FF/VI compared with two usual ICS/LABA fixed combination (fluticasone propionate/salmeterol \[FP/S\] or budesonide/formoterol \[BUD/F\]) in subjects with persistent asthma, in a "close to real life" settings. FF/VI will be administered once-daily (QD) via ELLIPTA dry powder inhaler (DPI) and FP/S or BUD/F will be administered twice daily (BID) via DISKUS™ and TURBUHALER™ DPI respectively. ELLIPTA is a new powder inhaler designed to be easy to use. The total duration of subject participation will be approximately 6 months (24 weeks).
