Teprotumumab

Teprotumumab is a fully human monoclonal antibody targeting the insulin-like growth factor 1 receptor, revolutionizing the medical management of active thyroid eye disease. By blocking receptor signaling on orbital fibroblasts, it reduces inflammation, halts tissue expansion, and drives significant proptosis reduction and soft tissue improvement. Infused every three weeks for eight infusions, it offers an effective alternative to surgical decompression. Clinical monitoring must account for adverse effects, notably hyperglycemia and manageable hearing impairment.
