Introduction: The initial clinical trials for teprotumumab excluded patients with previous orbital irradiation, surgery, glucocorticoid use (cumulative dose > 1gm), or biologic treatment. Therefore, information on the use of teprotumumab for patients who failed prior therapy is limited. Our purpose is to characterize the efficacy of teprotumumab for the treatment of recalcitrant TED.Methods: This is a multicenter retrospective study of all patients t...

Objectives: The insulin-like growth factor I receptor (IGF-1R) plays a significant role in the pathology of thyroid eye disease (TED), an autoimmune disorder characterized by orbital inflammation. Teprotumumab, a human monoclonal antibody targeting IGF-1R, has demonstrated efficacy in treating moderate-to-severe TED. A significant proportion of patients experienced adverse events (AEs), with 74% and 85% reporting an AE and 12% and 5% reporting serious AEs in Phase 2 and 3 tria...
