What is Tepezza (teprotumumab-trbw) for?

Tepezza (teprotumumab-trbw) is an inhibitor of the insulin-like growth factor-1 receptor (IGF-1R) indicated for the treatment of active thyroid eye disease (TED), which is also known as Grave’s eye disease.^[1]

It is available as intravenous powder for injection containing 500 mg teprotumumab-trbw.^[1]

How does Tepezza (teprotumumab-trbw) work?

TED is an autoimmune disease in which the immune cells attack the thyroid gland. As a result, this gland starts producing an excess of thyroid hormone, which causes the fat and muscle tissue of the thyroid gland to become swollen. This can cause symptoms like eye bulging, double vision, eye pain, and redness.^[2]

The insulin-like growth factor-1 receptor (IGF-1R) plays a role in the development of TED, but how exactly is not yet known. Teprotumumab-trbw can bind to IGF-1R and block its activation and signaling, thereby reducing fat and muscle swelling and improving TED symptoms.^[1,2]
