Study type
Interventional
Description of intervention(s) / exposure
The intervention is inhaled budesonide/eformoterol (Vannair (Registered Trademark) 200/6 micrograms) two actuations taken twice daily and as required for asthma symptom relief as per the "SMART" (Single combination inhaler as Maintenance And Reliever Therapy) regime. The duration of the intervention is 24 weeks. There is no subsequent follow-up period planned.

Treatment: Drugs
Comparator / control treatment
The control is inhaled budesonide/eformoterol (Vannair (Registered Trademark) 200/6 micrograms) two actuations taken twice daily along with a salbutamol inhaler (Ventolin (Registered Trademark) 100 micrograms) taken as required for asthma symptom relief (the "Standard" treatment regime). The duration of the control treatment is 24 weeks. There is no subsequent follow-up period planned.

Outcomes
Primary outcome [1] 257710 0
The proportion of high beta-agonist use episodes in the SMART group compared with the Standard Group as defined by the proportion of patients in the SMART group who at any point within the 24 week study period used greater than 8 actuations of Vannair as a reliever per 24 hour period compared to the proportion of patients in the Standard group who used greater than 16 actuations of Ventolin in a 24 hour period, as recorded by the electronic monitoring devices.
Timepoint [1] 257710 0
As assessed after the 24 week study period on the data from the electronic monitoring devices.
Secondary outcome [1] 263057 0
Asthma Control Questionnaire (ACQ) Score
Timepoint [1] 263057 0
As assessed after 24 weeks of treatment and compared with the baseline score.
Secondary outcome [2] 263058 0
The proportion of patients in the SMART group who markedly overuse Vannair as a reliever (defined as greater than 12 and 16 reliever actuations per 24 hour period) compared with Standard group patients who markedly overuse salbutamol as a reliever (defined as greater than 24 and 32 Ventolin actuations per 24 hour period respectively), as recorded by the electronic monitoring devices.
Timepoint [2] 263058 0
As assessed after the 24 week study period on the data from the electronic monitoring devices.
Secondary outcome [3] 263059 0
The proportion of patients who underuse their maintenance Vannair treatment in the SMART versus Standard groups, defined as 0 or 1 inhalations within a 24 hour period, as recorded by the electronic monitoring devices.
Timepoint [3] 263059 0
As assessed after the 24 week study period on the data from the electronic monitoring devices.
Secondary outcome [4] 263060 0
Patterns of use of reliever Vannair and salbutamol around the time of exacerbations. Exacerbation data will be recorded from patients at study visits and patterns of use of reliever medication will be obtained from the electronic monitoring devices.
Timepoint [4] 263060 0
As assessed from data collected at the time of study visits over the 24 weeks of treatment.
Secondary outcome [5] 263061 0
Number of severe exacerbations in the SMART versus Standard groups. Exacerbation data will be recorded from patients at study visits.
Timepoint [5] 263061 0
As assessed from data collected at the time of study visits over the 24 weeks of treatment.
