A Randomized Clinical Trial to Evaluate the Effects of Atorvastatin on Graves' Orbitopathy (GO): the STAGO-2 Study

• Status: Not yet recruiting
• Trial end date: 2024-12-31

Summary

Graves' orbitopathy (GO) is the most common extra-thyroidal manifestation of Graves' disease (GD). Based on its clinical signs and symptoms, GO is graded as mild, moderate-to-severe, or severe, and active or inactive, the latter feature being established on a 5/7-scale score named Clinical Activity Score (CAS).

The European Group on Graves Orbitopathy (EUGOGO) has recently formulated and published up-to-date guidelines for the management of GO, according to which high dose intravenous (iv) glucocorticoids (GC) (ivGC) is the first line treatment for moderate-to-severe and active GO. A protective effect of atorvastatin on the development of GO in patients with GD has been reported, based on which we recently conducted a phase II, randomized, open label clinical trial and found that atorvastatin improves the response of GO to ivGCs in hypercholesterolemic patients. The effect was unrelated to cholesterol levels, suggesting that it may be the consequence of a direct action of atorvastatin. To investigate this issue further and to introduce atorvastatin in the clinical practice, we designed the present Phase III, double-blinded, multicenter, randomized, adaptive, superiority, no profit, clinical trial to evaluate the effects of atorvastatin on Graves' Orbitopathy (GO) in patients with moderate-to-severe and active GO subjected to intravenous glucocorticoid therapy, regardless of cholesterol levels.
