This study is looking at how well a medicine called **satralizumab** works for people with **Thyroid Eye Disease (TED)**. Satralizumab is a special medicine that blocks a protein called **interleukin-6 (IL-6)**, which can help reduce swelling and pain in the eyes. The study wants to see if it's safe and effective to use. **Pharmacokinetics** means how the body absorbs and processes the medicine, and **pharmacodynamics** means how the medicine affects the body.
- Participants must have TED and meet certain health criteria.
- Those who need immediate eye surgery or have other serious eye problems might not be eligible.
- Pregnant or breastfeeding women cannot join this study.
The study involves taking satralizumab through a small needle under the skin. Participants will be monitored to see how they respond to the treatment. The study will help doctors understand if satralizumab is a good option for treating TED. If you have TED and meet the criteria, you might consider joining to help advance research. Always discuss with your doctor to ensure it's right for you.
