Clinical Trial Summary

Graves' disease (GD) is the most frequent cause of hyperthyroidism in iodine sufficient countries and Graves' orbitopathy (GO) is its most common extrathyroidal manifestation. Restoration and maintenance of euthyroidism are imperative in Graves' disease patients with GO. The main treatment options for Graves' hyperthyroidism are antithyroid drugs, radioactive iodine (RAI), and surgery. Whether one or the other therapy for Graves' hyperthyroidism offers the best protection against GO is not established. The study is aimed at comparing the effects of a conservative approach (antithyroid drugs, ATDs, experimental arm) vs an ablative approach (radioiodine or total thyroidectomy) of thyroid treatment on the overall outcome of GO in patients with GD and moderate-to-severe and active GO treated with intravenous glucocorticoids.
