Introduction Subjects with severe Th2-high endotype usually respond to oral corticosteroids (OCS). However, they often require high dosages with incremental side effects and healthcare costs. The advent of biological therapies provides an effective strategy to improve asthma control, as well as reduce OCS use. Various molecules have been developed, each targeting different pathways. We analyzed the two anti IL-5 strategies, benralizumab and mepolizumab, based on pivotal trials (RCTs), mechanisms of action and their possible role on the steroid-sparing effect. Areas covered This review analyzes the data from the benralizumab and mepolizumab RCTs, focusing on the advantages of each drugs on clinically efficacy and the steroid-sparing effect. Expert opinion Benralizumab may represent a promising therapeutic option in the treatment of eosinophilic asthma, due to its mechanism of action, which rapidly allows a reduction in the eosinophils' number, and a greater steroid-sparing effect.
