Severe exacerbations through Week 52
No biomarker requirementTrial 2

No statistically significant differences were observed during the 52-week treatment period in patients with baseline blood eosinophils <150 cells/μL taking DUPIXENT 200 mg or 300 mg + SOC and in the ≥150 to <300 cells/μL eosinophil subgroup treated with DUPIXENT 200 mg + SOC vs matching placebo + SOC.1

  • a ITT population was unrestricted by minimum baseline eosinophils or other Type 2 biomarkers (eg, FeNO or IgE).3
  • b For inclusion in the study, all patients were required to have had ≥1 severe asthma exacerbation in the prior year. Placebo-treated patients with greater numbers of prior exacerbations had greater numbers of exacerbations during the treatment period. A severe asthma exacerbation was defined as deterioration of asthma requiring the use of systemic corticosteroids for ≥3 days or asthma-related hospitalization or emergency department visit requiring systemic corticosteroids between the first dose and last dose plus 14 days. Subjects with baseline eosinophil levels >1500 cells/μL (<1.3%) were excluded.1,4
