Patent No. EP3107575 (titled "Methods For Treating Or Preventing Asthma By Administering An Il-4R Antagonist") was filed by Regeneron Pharmaceuticals on Feb 20, 2015. The application was issued on Sep 1, 2021.

Patent Summary

Reducing asthma exacerbations and improving asthma symptoms in severe asthma patients by using an IL-4 receptor antagonist drug. The IL-4R antagonist is administered to severe asthma patients along with their usual controller medications like inhaled corticosteroids and reliever medications like albuterol. The IL-4R antagonist reduces the incidence of asthma exacerbations compared to controller therapy alone. It also improves asthma parameters like FEV1 lung function. This provides a targeted therapy option for severe asthma patients who have inadequate control despite high corticosteroid doses.
