A randomized study to evaluate the efficacy and safety of combining mycophenolate mofetil with methimazole in patients with newly diagnosed Graves' disease.
The remission rate of methimazole standard therapy in patients with newly diagnosed Graves' disease is only around 50%. Main reason for the low remission rate is methimazole therapy is not a drug targeting etiology of Graves' disease. The investigators hypothesize that adding mycophenolate mofetil, an immunosuppressor, to methimazole standard therapy will improve remission rate. The study will evaluate the efficacy and safety of combining mycophenolate mofetil with methimazole in patients with newly diagnosed Graves' disease. 205 eligible patients will be randomized to mycophenolate mofetil combined with methimazole therapy or methimazole standard therapy. The primary outcome is the remission rate at 12 months.
