Efficacy and Safety of QGE031versus Placebo and Omalizumab in Patients Aged 18-75 Years With Asthma

Change From Baseline in ACQ-7 Score

The ACQ-7 measures asthma symptom control and consisted of 7 items: 5 on symptom assessment, 1 on rescue bronchodilator use and 1 on airway caliber (FEV1 % predicted). All 7 questions of the ACQ were equally weighted. Items 1-6 scored along a 7-point response scale, where 0 = good controlled and 6 = poor controlled. The 7th item on % predicted FEV1 (pre-bronchodilator) was scored by clinic staff on a 7-point scale (0 - \> 95%; 1 - 90-95%; 2 - 80-89%; 3 - 70-79%; 4 - 60-69%; 5 - 50-59%; 6 - \< 50%). The average score of the 7 questions was calculated as the sum of scores divided by the number of questions that were answered by the participants, as long as there were at least 6 questions answered and the missing items were neither question 1 nor question 7. A negative change from baseline indicates improvement.
