Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Age 18 to 65 years at the time of informed consent

Must not have

Active thyroid eye disease (clinical activity score [CAS] ≥3) with functional visual impairment sufficient to cause poor quality of life, or dysthyroid optic neuropathy likely to require immunosuppressive treatment during the 30 weeks of the study

Summary

This trial is testing the withdrawal of Methimazole in people with Graves' disease. Participants will go through different periods, including screening, treatment with Methimazole or placebo, tapering off Methim

Who is the study for?

This trial is for individuals with Graves' disease who are currently taking Methimazole. Participants must have stable thyroid levels to join and will be grouped based on the size of their goiter. People cannot participate if they don't meet specific health criteria that aren't listed here.

What is being tested?

The study tests WP1302's ability to prevent relapse in Graves' disease after stopping Methimazole. It compares different doses of WP1302 (400, 800, or 1200 μg) against a placebo, alongside a tapering dose of Methimazole over several months.

What are the potential side effects?

Potential side effects are not specified but may include reactions similar to other immune-modulating drugs such as fatigue, digestive issues, skin reactions, or potential impact on thyroid hormone levels.

Group I: WP1302 400μgActive Control2 Interventions

After screening, eligible subjects will be randomized to treatment at a ratio (stratified by size of goiter \[grade 0 or 1; grade 2\], WHO classification) of 1:1:1:1 to either any group of MMI with WP1302 at a dose of 400 μg, 800 μg, or 1200 μg, or the group of MMI with placebo. The study consists of up to 5 periods: a screening period of up to 2 weeks; a WP1302 or placebo titration with MMI period of 12 weeks; a Full dose of WP1302 or placebo with MMI tapering period of 26 weeks; a follow-up period of 4 weeks; and an extended follow-up period of 6 months.
