Investigating a treatment for moderate-to-severe active thyroid eye disease
The purpose of this study is to evaluate the efficacy, safety and tolerability of subcutaneous teprotumumab in participants with moderate-to-severe active thyroid eye disease (TED). TED is an autoimmune disease in which the eye muscles and fatty tissue behind the eye become inflamed. This can push the eyes forward (bulging) or cause redness and swelling. Symptoms can range from mild to sight-threatening. Current treatment options for moderate/severe TED are not optimal (lots of side effects), but teprotumumab holds promise and is being tested for treatment of TED in this trial.
