A Study to Evaluate the Safety of Xolair in Moderate to Severe Persistent Asthma Patients (ALTO)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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.
