Abstract | BACKGROUND: Biologics have dramatically improved outcomes in severe T2-high asthma. Although the identification of patients with the best response is key to understand the efficacy of these agents and select the best target populations, the definition and predictors of super-response are not fully established yet. METHODS: This study aimed to describe super-response and to identify predictors of super-response to biologics in a French severe eosinophilic asthma cohort followed in a severe asthma tertiary care center between January 2005 and December 2020. Super-response was defined a priori as no oral corticosteroids intake and no exacerbations over 12 months. Collected data at baseline and after 12 months included asthma history, comorbidities, clinical characteristics, lung function, T2-biomarkers, baseline asthma-related treatments, and asthma control. RESULTS: Among 157 patients assessed for eligibility, 108 were included, corresponding to 166 treatments with biologics. Overall response rate was 63.2 % (105/166) and super-response rate was 39.7 % (66/166). In omalizumab group (n = 67), lower dose of oral corticosteroids in maintenance was the only factor associated with super-response (p = 0.008). In the anti-IL-5/anti-IL-5R group (n = 99), absence or lower dose of oral corticosteroids in maintenance and absence of eosinophilic granulomatosis with polyangiitis were statistically associated with super-response (p = 0.009, p = 0.001 and p = 0.02 respectively). CONCLUSION:
