What this Trial Is About

Researchers are evaluating rilzabrutinib in adult participants aged 18 to 75 years with Graves' disease, including those with and without Graves' orbitopathy. This open-label Phase 2 study aims to measure the treatment effects and safety of two different doses of rilzabrutinib. The study is sponsored by Sanofi and focuses on participants with active hyperthyroidism related to Graves' disease. Participants are randomly assigned to receive one of two oral doses of rilzabrutinib tablets. The study includes a screening period of up to 4 weeks, followed by a treatment period lasting up to 16 weeks. After treatment, there is a 4-week follow-up period. Throughout these phases, participants will attend up to 13 visits to monitor their response and safety. During the study, researchers will assess changes in thyroid hormone levels, specifically the percent change from baseline in free thyroxine (FT4) and free triiodothyronine (FT3) at Week 16. They will also evaluate how many participants achieve normal FT4 and FT3 levels. Safety will be monitored by tracking any adverse events and withdrawals related to treatment. Participants will undergo clinical evaluations and ophthalmic exams as needed during their involvement, which lasts about 24 weeks in total including screening and follow-up.
