Thyroid eye disease is a rare, progressive, autoimmune condition that causes the eyes to bulge (proptosis) and can lead to blindness. Until now, treatment has focused on managing its symptoms – which can include eye pain, double vision, or sensitivity to light – with steroids, and in some cases, multiple invasive surgeries.

The human monoclonal antibody and a targeted inhibitor of the insulinlike growth factor-1 receptor is administered to patients once every 3 weeks, for a total of eight infusions, according to a statement from Horizon Therapeutics, which manufactures the drug.

The approval was based on the findings from two similarly designed, parallel-group studies (Studies 1 and 2) involving 170 patients with thyroid eye disease who were randomized to receive either teprotumumab or placebo. Of those receiving the study drug, 71% in Study 1 and 83% in Study 2 had a reduction of more than 2 mm in eye protrusion, compared with 20% and 10%, respectively, among the placebo participants.

The most common adverse reactions in patients receiving teprotumumab were muscle spasm, nausea, alopecia, diarrhea, fatigue, and hyperglycemia. The treatment is contraindicated for pregnancy.
