Budesonide/Formoterol SPIROMAX

Difference in number of patients who receive treatment with biologics in the intervention arm compared with the control arm

Device mastery was defined as absence of healthcare professional (HCP)-observed errors by the end of Step 3 of a 6-step standardized device training protocol for empty Spiromax compared to empty Turbohaler. The 6 steps of device training protocol were: Step 1 - Intuitive use; Step 2 - Patient information leaflet; Step 3 - Instructional video; Step 4 - HCP tuition; Step 5 - HCP tuition (1st repeat); Step 6 - HCP tuition (2nd repeat).

Maintenance of device mastery was defined as absence of HCP-observed errors after 12 weeks of device use.

PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Baseline trough morning PEF was defined as the average value of recorded (nonmissing) morning assessments 5 out of the last 7 days prior to randomization. The first day before randomization consisted of the electronic patient diary entry at home on the morning of the randomization visit (Baseline \[Day 1\]) and the first day postrandomization consisted of the electronic patient diary entry at home on the morning of the day after the randomization visit (Baseline \[Day 1\]). For postdose weekly average of trough morning PEF measurements, the values were the averages based on the available data for that week. The averages were calculated as the sum of morning PEF values divided by the number of nonmissing assessments. The final value for change from baseline was calculated as the average of the weekly change from baseline averaged over 12 weeks.
