Multinational Drug Survival Study of Omalizumab in Patients With Chronic Urticaria and Potential Predictors for Discontinuation

Abstract

This multinational omalizumab drug survival cohort study demonstrated that treatment of chronic urticaria with omalizumab in a clinical setting is effective and safe, and well-controlled disease is the main reason for treatment discontinuation. These findings on omalizumab drug survival rates and reasons and potential predictors for discontinuation may guide patients and physicians in clinical decision-making and expectation management. These results may call for the identification of biomarkers for chronic urticaria remission in complete responders to omalizumab treatment.
