Official Title

A Randomised, Open-Label, Multicenter Study to Evaluate the Effect of Xolair (Omalizumab) as Add-on Therapy to Inhaled Corticosteroid + Long-Acting Beta Agonist in Fixed or Flexible Dosing Compared to Isolated Inhaled Corticosteroid + Long-Acting Beta Agonist in Fixed or Flexible Dosing in the Asthma-Related Quality of Life in Patients With Severe Persistent Allergic Asthma.
