Chronic spontaneous urticaria (CSU) is a devastating disease and is associated with many co-morbidities and long-lasting suffering. Therefore, patients always look for a most efficient therapeutic approach to achieve a full remission. In many patients, CSU remain refractory to off-label doses of antihistamines and short courses of steroids, and therefore are treated with omalizumab. However, 15–20% of severe CSU patients will stay unresponsive to omalizumab and are defined as being of un-met needs. In this review we will shed light on the many new drugs which are assessed in ongoing clinical trials.
