What You Need to Know Before You Apply

What is the purpose of this trial?

This is a study to assess the efficacy, safety, and tolerability of IMVT-1402 in adult participants with Graves' disease (GD) who are hyperthyroid despite antithyroid drug (ATD) treatment. The primary objective of this study is to evaluate the efficacy of IMVT-1402 versus placebo as assessed by T3 (total triiodothyronine \[T3\] or free triiodothyronine \[FT3\]), free thyroxine (FT4), thyroid-stimulating hormone (TSH), and ATD dose at Week 26.

Will I have to stop taking my current medications?

The trial requires participants to continue taking their antithyroid drugs (ATD) at a stable dose before and during the study. If you are on other medications, the protocol does not specify whether you need to stop them.

Are You a Good Fit for This Trial?

This trial is for adults with Graves' disease who still have hyperthyroidism despite being on antithyroid drugs. Participants must have a confirmed diagnosis, low TSH levels, and been treated with a significant dose of methimazole or equivalent. They should be on a stable ATD dose before the study starts.

Inclusion Criteria

I have been taking a specific dose of thyroid medication for the last 4 weeks.

I have been diagnosed with Gaucher's Disease.

I expect to be on a stable dose of my thyroid medication for the next 4 weeks.
