Abstract
Asthma is a chronic inflammatory condition that affects the lung airways. Chronic use of oral glucocorticoids in patients with severe asthma is associated with several adverse events (AEs). Biologics (omalizumab, benralizumab, mepolizumab, reslizumab, and dupilumab) have been developed as alternative therapies for the treatment of asthma. In this study, we aimed to evaluate the risk of anaphylactic reactions associated with these five biologics based on a large global database. We utilized individual case reports from the Uppsala Monitoring Center from January 1968 to December 29, 2019. A disproportionality analysis was performed over all drugs and monoclonal antibodies.
Anaphylactic reactions were defined according to the "anaphylactic reaction” of the standardized MedDRA queries. Contrary to dupilumab, omalizumab, benralizumab, and mepolizumab demonstrated positive signals related to anaphylactic reactions over all drugs and monoclonal antibodies. Reslizumab, which represented only 315 cases of all AEs, requires more reports to determine its association with anaphylactic reactions. More anaphylactic reactions have been identified than are known, and most cases (96.2%) are reported to be serious. Our findings indicate that omalizumab, benralizumab, and mepolizumab for asthma treatment are associated with a high risk of anaphylactic reactions; thus, more careful monitoring in the post-administration period is recommended.
