A Study to Evaluate the Safety of Xolair in Moderate to Severe Persistent Asthma Patients (ALTO)

Study Overview
=================
Brief Summary
-----------------
This was a multicenter, open label, randomized, controlled, safety trial in subjects aged 6-75 years with a diagnosis of moderate to severe, persistent asthma. A total of 1899 subjects were randomized (2:1) to either the active treatment group or the control group. Upon successful completion of the screening period ( 2 weeks), each subject entered the 24 week study.
