Teprotumumab is a human monoclonal antibody used to treat adults with active thyroid eye disease (TED). TED is a rare autoimmune disease that causes the muscles and fatty tissues around the eyes to become swollen, which can lead to vision loss, double vision, and other eye problems. By targeting and blocking the activity of the insulin-like growth factor 1 receptor (IGF-1R), teprotumumab prevents the growth of the affected muscles and fat, reducing the symptoms of TED. Teprotumumab is administered via intravenous infusion every three weeks.
Teprotumumab, sold under the brand name Tepezza, is a medication specifically designed to treat thyroid eye disease (TED) [1, 2]. TED, also known as Graves' eye disease, is an autoimmune condition where the immune system attacks the tissues and muscles behind the eye [3]. This leads to inflammation, swelling, and various other symptoms that can significantly impact vision and overall well-being.
Here's a closer look at Teprotumumab:
- Mechanism of Action: Teprotumumab belongs to a class of medications called monoclonal antibodies [2]. It works by targeting a specific protein called the insulin-like growth factor 1 receptor (IGF-1R) [2, 4]. This receptor is involved in the inflammatory processes associated with TED [4]. By binding to IGF-1R, Teprotumumab helps reduce inflammation and swelling behind the eye [2].
- Uses: Teprotumumab is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with moderate to severe active TED [1]. It is typically used in cases where other treatments, such as steroids or immunosuppressive medications, haven't been effective [5].
- Dosage and Administration: Teprotumumab is administered intravenously (through a vein) by a healthcare professional in a clinic setting [5]. The specific dosage and treatment schedule will be determined by your doctor based on your individual needs.
- Important Notes:
- Teprotumumab is a relatively new medication, and long-term side effects are still being studied [5].
- It's crucial to discuss any potential risks and benefits with your doctor before starting treatment with Teprotumumab [5].
- This medication is not suitable for everyone, and some people may not be candidates due to underlying health conditions or other factors [5].
