Introduction: Thyroid eye disease (TED) is an autoimmune disease characterized by inflammation of orbital and extraocular muscles. It induces proptosis and diplopia, leading to a worsening of quality of life (QoL) because of its impact on physical appearance, and visual function. The natural history involves an 'active TED,' which is an autoimmune inflammatory response targeting orbital soft tissues, and 'inactive TED,' where there is tissue expansion remodeling. To date, glucocorticoids represent the main medical therapy, even if often ineffective and associated with side effects. Areas covered: In TED, the autoimmune process leads to production of TSH-R and IGF-1 R autoantibodies. This induces inflammatory changes in the orbital tissue, and activation of fibroblasts with accumulation of glycosaminoglycans, leading to consequent proptosis, and diplopia. In two previous randomized, double-masked, placebo-controlled, parallel-group, multicenter trials, teprotumumab has been shown to be effective in improving proptosis, inflammation, diplopia, and QoL. More recently, it has been shown that teprotumumab is also effective in chronic-inactive TED. Teprotumumab was approved by the FDA on 21 January 2020 for the treatment of TED. Expert opinion: For the above-mentioned reasons teprotumumab represents a potential first line therapy for TED that could replace the use of steroids in the next future.

Abstract

Introduction: Thyroid eye disease (TED) is an autoimmune disease characterized by inflammation of orbital and extraocular muscles. It induces proptosis and diplopia, leading to a worsening of quality of life (QoL) because of its impact on physical appearance, and visual function. The natural history involves an 'active TED,' which is an autoimmune inflammatory response targeting orbital soft tissues, and 'inactive TED,' where there is tissue expansion remodeling. To date, glucocorticoids represent the main medical therapy, even if often ineffective and associated with side effects. Areas covered: In TED, the autoimmune process leads to production of TSH-R and IGF-1 R autoantibodies. This induces inflammatory changes in the orbital tissue, and activation of fibroblasts with accumulation of glycosaminoglycans, leading to consequent proptosis, and diplopia. In two previous randomized, double-masked, placebo-controlled, parallel-group, multicenter trials, teprotumumab has been shown to be effective in improving proptosis, inflammation, diplopia, and QoL. More recently, it has been shown that teprotumumab is also effective in chronic-inactive TED. Teprotumumab was approved by the FDA on 21 January 2020 for the treatment of TED. Expert opinion: For the above-mentioned reasons teprotumumab represents a potential first line therapy for TED that could replace the use of steroids in the next future.
