Where possible, information in this table relates to phase 3 trial populations with blood eosinophils ≥300 cells·μL⁻¹ and using current licensed doses. Quality of life relates to AQLQ only. ^#: see Hanania et al. [25]. ^¶: the data presented relate to the subgroup with blood eosinophils ≥300 cells·μL⁻¹; this population had ≥3 exacerbations in the previous 12 months, which is higher than the other phase 3 studies. ⁺: exacerbation rate is difficult to compare across biologics due to differing study populations (e.g. moderate-to-severe asthma), different inclusion criteria (e.g. eosinophil count threshold) and size of placebo responses. ^§: see Normansell et al. [11]. ^ƒ: FEV₁ improvement: +/− indicates unclear or inconsistent results; + indicates improvement of ∼100 mL to <200 mL; ++ indicates improvement of ≥200 mL. ^##: for CRwNP: + indicates significant improvement in SNOT-22 score or severity of disease; ++ indicates improvement in both. ^¶¶: improvement with dupilumab larger magnitude than with mepolizumab/omalizumab. ⁺⁺: this may result in more than one injection to achieve the correct dose.
