Teprotumumab, sold under the brand name Tepezza, is a medication used to treat adults with thyroid eye disease, a rare condition where the muscles and fatty tissues behind the eye become inflamed, causing the eyes to bulge outwards.[2][3]

The most common side effects are muscle spasm, nausea, hair loss, diarrhea, fatigue, high blood sugar, hearing loss, dry skin, altered sense of taste, and headache.[3] Teprotumumab should not be used if pregnant, and women of child-bearing potential should have their pregnancy status verified prior to beginning treatment and should be counseled on pregnancy prevention during treatment and for six months following the last dose.[3]

It is a human monoclonal antibody developed by Genmab and Roche[4] for tumour treatment but was later researched by River Vision Development Corporation and Horizon Therapeutics to be used for ophthalmic uses.[5] It binds to IGF-1R.[1]

Teprotumumab was approved for use in the United States in January 2020.[3][6][7][8] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[9]
