A new drug has been approved in the US for thyroid eye disease, a rare condition in which the muscles and fatty tissues behind the eye become inflamed, causing the eyes to bulge. Tepezza (teprotumumab) is a monoclonal antibody that targets the insulin-like growth factor-1 receptor with the goal of modifying the course of the disease. In issuing the approval, the Food and Drug Administration said Tepezza is the first non-surgical treatment for thyroid eye disease, which can cause eye pain, double vision and sensitivity to light.
