About this trial
Asthma management has been revolutionised by the development of biological therapies. Dupilumab is an anti-interleukin4 receptor marketed in 2020 for severe asthmatic patients with 2 exacerbations or more within the last 12 months. Although data showed that safety and efficacy of dupilumab are sustained when treatment is extended up to 3 years, no study has emerged regarding dupilumab discontinuation. This study aims to demonstrate the non-inferiority regarding strategy failure at 24 months of stopping dupilumab (intervention group) compared with its continuation (control group) in controlled asthma patients receiving this drug for at least 3 years.
Eligibility criteria

Patients with Forced expiratory volume in one second ≤ 30% of predicted values
Patients treated by an oral corticosteroid dose ≥ 10 mg/day (in prednisone equivalent)
Patients who have to discontinue dupilumab for a reason other than controlled asthma, such as an adverse drug reaction, a planned or current pregnancy, or a planned switch to another biologic indicated in severe asthma
