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).

Clinical Trial Outcome Measures
- Change From Baseline in Asthma Control Test (ACT) Total Score at Week 12
- Time Frame: Baseline and Week 12
- The ACT is a validated self-completed questionnaire consisting of 5 questions that evaluate asthma control during the past 4 weeks on a 5-point categorical scale. Total scores are calculated from the sum of the scores from the 5 questions and can range from 5 to 25, with higher scores indicating better control. An ACT total score of 5 to 19 suggests that the participant’s asthma is unlikely to be well controlled, whilst a score of 20 to 25 suggests that the participant’s asthma is likely to be well controlled. Baseline value was the last assessment prior to randomization (Day 0). Change from Baseline was post-dose visit value minus the Baseline value. Least square mean change is presented.
- Change From Baseline in ACT Total Score at Week 24

- Percentage of Participants With Correct Use of Device, Defined as Not Making Any Critical or Non-critical Errors, at Week 12, and at Week 24 Independently of the Use at Week 12
- Time Frame: Week 12 and Week 24
- Participants were asked to read the appropriate package insert for their prescribed inhaler and then the investigator (or suitably qualified designee) demonstrated the proper use of the inhaler. The participant was then asked to self-administer their first dose of study treatment under the supervision of the investigator and any critical and non-critical errors were recorded. Individual instruments for assessing correct inhaler use were provided for each of the three devices used in this study.
