BACKGROUND: There are no prospective studies comparing how biological therapies affect nonsteroidal anti-inflammatory drug (NSAID) tolerance in NSAID-exacerbated respiratory disease. OBJECTIVE: To study the induction of NSAID tolerance after biological therapy in patients with NSAID-exacerbated respiratory disease. METHODS: A prospective pilot study in a real-world clinic setting was conducted among subjects with severe asthma and type 2 inflammation. A random allocation of therapy was carried out: benralizumab, dupilumab, mepolizumab, or omalizumab. NSAID intolerance was confirmed by an oral challenge test (OCT) using acetyl-salicylic acid (ASA-OCT). The principal outcome was NSAID tolerance according to OCT before and after 6 months of each biological therapy (intragroup comparisons). As exploratory outcomes, we compared NSAID tolerance between biological therapies (intergroup comparisons). RESULTS: A total of 38 subjects were included; 9 received benralizumab, 10 dupilumab, 9 mepolizumab, and 10 omalizumab. There was an increase in the concentration needed to produce a reaction during ASA-OCT with omalizumab (P < .001) and dupilumab (P = .004) but not with mepolizumab and benralizumab. Omalizumab and dupilumab achieved the highest frequency of NSAID tolerance (omalizumab 60%, dupilumab 40%, mepolizumab 22%, and benralizumab 22%). CONCLUSIONS: Biological therapies for asthma are useful for inducing NSAID tolerance; however, in patients with type 2 inflammation and high levels of total IgE, atopy, and eosinophils, anti-IgE or anti-IL4/13 seem to be more effective than antieosinophilic therapies. Omalizumab and dupilumab increased ASA tolerance, whereas mepolizumab and benralizumab did not. Future trials will be able to clarify this finding.
