Real-World Characteristics of Patients with Severe Asthma prior to Starting Dupilumab: The ProVENT Study

INTRODUCTION: Dupilumab is approved for the treatment of severe type 2 (T2) asthma; however, the characteristics of patients receiving dupilumab in routine clinical practice are incompletely understood. This study describes the characteristics of patients with severe asthma before dupilumab treatment in a real-world setting. METHODS: This interim analysis of an ongoing real-life study of dupilumab assessed baseline characteristics of the first patient cohort enrolled in the ProVENT study. RESULTS: A total of 99 patients (59% females) were analyzed (17% received another biologic before dupilumab treatment and 15% were on maintenance oral corticosteroid treatment). Adult-onset asthma (>18 years) and an allergic phenotype were documented in 58% and 48% of patients, respectively. Median (interquartile range) age was 54 (40-61) years; the median number of exacerbations in the last 24 months was 1 (0-3); median fractional exhaled nitric oxide (FeNO) value was 38 (23-64) ppb; and median blood eosinophils (bEOS) count was 184 (8-505) cells/µL. According to the United Kingdom Severe Asthma Registry classification, 53% of patients had T2 intermediate asthma (bEOS
