About Thyroid Eye Disease
Thyroid eye disease (TED) is a rare autoimmune disease that is active for up to three years. During active TED the insulin-like growth factor receptor (IGF-1R) is overexpressed on orbital fibroblasts, resulting in local inflammation and tissue expansion, which can in turn lead to proptosis, or bulging of the eye. This can result in stiffness of the muscles, displacement of the eyes so they are no longer in line with each other, and/or the eyelids are unable to close. The inability for people living with active TED to close their eyelids can lead to corneal ulcerations and potential blindness, and many also endure challenges with double vision, known as diplopia.
About Teprotumumab
Teprotumumab is a fully human monoclonal antibody (mAb) and a targeted inhibitor of the insulin-like growth factor 1 receptor (IGF-1R). Teprotumumab has received Breakthrough Therapy, Orphan Drug and Fast Track designations from the U.S. Food and Drug Administration (FDA). A Phase 3 confirmatory study was launched in October 2017 after results from the randomized double-blind, placebo controlled Phase 2 study. Results from this study were published in the May 4, 2017, issue of The New England Journal of Medicine.
The Phase 2 study was designed to evaluate the efficacy and safety of teprotumumab in patients with recent onset, moderate-to-severe active TED. The primary endpoint was response in the study eye defined as a reduction in Clinical Activity Score of ≥ 2 points and reduction of proptosis of ≥ 2 mm at week 24. In the intent-to-treat population, 29 of 42 (69%) patients receiving teprotumumab and 9 of 45 (20%) patients receiving placebo were responders at week 24 (p˂0.001). The most frequent adverse events reported (≥ 5 percent) were nausea, muscle spasms, dysgeusia, diarrhea, alopecia, hyperglycemia, dry skin, headache, paresthesia, hearing impairment and weight loss. Teprotumumab is an investigational medicine and its safety and efficacy have not been established.
