A Study to Assess the Efficacy, Safety, and Tolerability of IMVT-1402 as Treatment for Adult Participants With Graves' Disease

Purpose

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.
