A Study to Investigate the Efficacy, Safety, and Tolerability of IMVT-1402 in adult participants with Graves' disease (GD) who are hyperthyroid despite antithyroid drug (ATD) treatment.
Trial Details
Brief Summary: 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. Mainly 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.
The investigational treatment being examined in the FORWARD program clinical studies, IMVT-1402, is thought to work in a different way than currently available antithyroid drugs. It is designed to target the underlying cause of Graves’ disease.
