The incidence and prevalence of the long-term use of omalizumab for chronic idiopathic urticaria.

The objective of the drug utilization study is to determine real-world omalizumab use patterns in patients with chronic idiopathic urticaria (CIU). The focus is on identifying the incidence and prevalence of use beyond 24 weeks. 

A companion systematic review (RE0043) will determine the efficacy, effectiveness, and safety of omalizumab administered for 24 weeks or longer in patients with CIU. The review will also identify the characteristics of patients who use omalizumab for longer than 24 weeks.
