Abstract
PURPOSE: To present a rare, to our knowledge previously undescribed, case of successful AFRS management using stapokibart (CM310). PATIENTS AND METHODS: The laboratory, immunological, symptom scores and imaging datas before and after stapokibart treatment were evaluated to determine the effect of stapokibart on AFRS. RESULTS: After four weeks of treatment, the patient showed significant clinical improvement, including a marked reduction in nasal polyp size and the near-complete return of normal olfaction. By week 16, lab tests confirmed a substantial drop in eosinophils and IgE, and a follow-up CT scan showed complete resolution of sinus inflammation. The patient reported high satisfaction due to a major improvement in quality of life. CONCLUSION: This pioneering case demonstrates that stapokibart, a novel anti-IL-4Rα antibody, is a promising and effective treatment for refractory AFRS, showing a rapid onset of action and sustained control of type 2 inflammation.
