New drug aims to tame Graves' disease Long-Term
NCT ID NCT07286006
First seen Jun 25, 2026 · Last updated Jul 28, 2026 · Updated 3 times
Summary
This study tests a drug called IMVT-1402 in adults with Graves' disease, a condition where the immune system attacks the thyroid. The goal is to see if the drug can help patients stay healthy without needing other treatments. About 372 people who completed earlier studies will take the drug for up to 52 weeks.

- What this could lead to
- If successful, this could point toward a way to keep Graves' disease under control without needing lifelong medication.
- What could go wrong
- This is an early phase 2 extension study, so results are not yet proven. The drug may not work for everyone, and side effects are still being studied.
