New drug aims to tame overactive thyroid without lifelong pills
NCT ID NCT07018323
First seen Jun 25, 2026 · Last updated Aug 26, 2026 · Updated 8 times
Summary
This trial tests a new drug called IMVT-1402 for adults with Graves' disease, a condition where the thyroid is overactive. The study will include 210 participants who still have high thyroid levels despite taking standard medications. Participants will receive either one of two doses of IMVT-1402 or a placebo for 26 weeks. The main goal is to see if the drug can help patients achieve normal thyroid function and stop taking other thyroid medications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IMVT-1402
- What this could lead to
- If successful, this could offer a new treatment option for Graves' disease that helps patients achieve normal thyroid function without needing ongoing antithyroid drugs.
- What could go wrong
- This is an early Phase 2b trial with only 210 participants, so results may not apply to everyone. The drug may not work better than placebo, and side effects are still being studied.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * Participants with the ability to understand the requirements of the trial, provide written informed consent, and comply with the trial protocol procedures. * Male or female participants aged ≥ 18 years. * Participants with diagnosis of GD who are hyperthyroid despite ATD treatment. * Other, more specific inclusion criteria are defined in the protocol. Exclusion Criteria: * Have previously been successfully treated with radioactive iodine (RAI) therapy or have undergone total thyroidectomy. * Have an autoimmune disease other than GD requiring treatment that, in the Investigator's judgment, puts the participant at undue risk. * Have moderate-to-severe active thyroid eye disease (TED) and are expected to require immediate surgical intervention and/or are planning corrective surgery/irradiation or medical therapy for TED during study participation. * Additional exclusion criteria are defined in the protocol.
