Researchers are evaluating IMVT-1402 in a global, randomized, double-blind, placebo-controlled Phase 2b study for adults with Graves disease GD who remain hyperthyroid despite antithyroid drug ATD treatment. The study aims to assess the efficacy, safety, and tolerability of IMVT-1402 in this population. Participants will receive one of two doses of IMVT-1402 or a placebo for 26 weeks. The study includes two experimental groups with different doses of IMVT-1402 and a placebo comparator group. Treatments are given over the same 26-week period to evaluate their effects. During the study, participants will be monitored to see if they become euthyroid and are able to stop ATD by Week 26. Researchers will measure thyroid hormone levels such as triiodothyronine T3 and free thyroxine FT4 at various time points, including Weeks 2, 4, and 26. Safety and tolerability will also be assessed throughout the trial, which is expected to complete in May 2027.
