• Study description:
  Severe asthma, affects for 5 to 10% of asthma patients.Biologic therapies have emerged as effective treatments for severe asthma, and five monoclonal antibodies (mAbs) are now available in France to target different subtypes of severe asthma. Intensity of clinical response varies from patient to patient: therefore, for patients with insufficient response, a switch to another drug is possible, since most of the biologics target similar populations of patients with severe asthma. Although response to a biologic given as a second or third line of treatment has been documented, the best strategy to switch from a molecule to another one has not been evaluated yet. In case of failure of anti-IL5 or anti IL5R drugs, two main strategies are used: switching to dupilumab, an anti IL4/13R mAb that also targets eosinophilic asthma or switching to another anti IL5 drug. This study aimed to compare the efficacy of the two switching strategies on asthma control in patients with severe eosinophilic asthma with insufficient clinical response to a first-line anti-IL5/5R mAb treatment. We planned an emuation of a target trial using the data of the Research on severe asthma cohort (RAMSES-cohort). We planned to use a propensity score framework to deal with potential cofounders to the observational nature of the data.
