• Introduction: Teprotumumab is a fully human IgG1 monoclonal antibody directed against the human insulin-like growth factor-1 receptor. Following a clinical trial in which its efficacy in the treatment of thyroid eye disease (TED) was assessed, it received "breakthrough therapy" designation from the FDA in 2016 and was approved by the FDA in January 2020 for the treatment of TED. Thyroid eye disease is a potentially debilitating complication of Graves' Disease involving inflammation and tissue remodeling behind the eye, and previous treatment options typically involved multiple invasive surgeries-teprotumumab is the first drug ever approved for the treatment of TED and therefore represents a significant step forward in the treatment this disease.

Pharmaceutical Information

• Pharmacodynamics: Teprotumumab inhibits the downstream effects of IGF-1R signaling, namely tissue inflammation and remodeling, which are responsible for the various symptoms of thyroid eye disease. Teprotumumab may cause disease flares in patients with pre-existing inflammatory bowel disease (IBD)-patients experiencing an exacerbation should discontinue therapy with teprotumumab. Significant hyperglycemia has been observed in patients receiving treatment with teprotumumab which may require antihyperglycemic medications. Based on its Mechanism of action, it is likely that teprotumumab will cause fetal harm in pregnant woman-for this reason, females of child-bearing age should use effective contraception prior to initiation, during therapy, and for 6 months following the last dose of teprotumumab.
• Targets: Insulin-like growth factor 1 receptor
