QBX258 infusion, a combination of VAK694 and QAX576, was supplied to the Investigator as open label bulk medication. The planned dose of VAK694 (lyophilisate in vial, 150 mg/vial), was 3 mg/kg. The planned dose of QAX576 (lyophilisate in vial, 150 mg/vial), was 6 mg/kg.
The placebo infusion was an equal volume of 5% dextrose for infusion and was provided by the clinical site.

Change From Baseline in Asthma Control Questionnaire (ACQ) Score
The ACQ consists of 7 questions assessing symptoms, rescue medication use and lung function. Except for lung function (FEV1), each question was scored on a 7-point scale where 0 = no impairment and 6 = maximum impairment. Scores ranged between 0 totally controlled to 6 (severely uncontrolled). Participants with a score below 1.0 are considered to have adequately controlled asthma. Participants with a score above 1.0 were considered not to be well controlled. A negative change from baseline indicates improvement.
Time frame: Baseline and 12 weeks
Change in Forced Expiratory Volume in One Second (FEV1)
FEV1 was assessed using central spirometry according to the American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines.
Time frame: Baseline and 12 weeks
Change in Asthma Quality of Life Questionnaire (AQLQ) Score
The AQLQ is a 32-item disease specific questionnaire designed to measure functional impairments that are most important to patients with asthma. It consists of 4 domains: symptoms, emotions., exposure to environmental stimuli and activity limitation. Patients were asked to recall their experiences during the previous 2 weeks and to score each item on a 7-point scale. The scale ranges from 1 to 7. The overall AQLQ score was the mean response to all 32 questions. Higher scores represent better outcomes.
Time frame: Baseline and 12 weeks
Morning and Evening Peak Expiratory Flow (PEF) Rate
Morning and evening PEFs were recorded on an electronic diary (e-diary). PEF was assessed twice daily approximately 12 hours apart and the measurements were recorded in the e-diary.
Time frame: Baseline and 12 weeks
Change From Baseline in Maximum Expiratory Flow
Maximum expiratory flow was assessed using central spirometry according to the American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines.

Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO)
FeNO was assessed as a measure of airway inflammation. An FeNO machine was used to obtain the FeNO measurements. FeNO measurements were obtained prior to the spirometry assessments.
Time frame: baseline, 12 weeks
