Brief summary

Behcet's syndrome (BS) is a multisystem autoimmune vasculitis. Current clinical treatment primarily includes glucocorticoids, immunosuppressants, and molecularly targeted drugs such as TNF-α and IL-6 inhibitors; however, some patients still respond poorly to existing treatment regimens. The JAK-STAT signaling pathway serves as a common downstream signaling pathway for various cytokines involved in the pathogenesis of Behcet's syndrome. Upon binding to their receptors, cytokines activate JAK kinases, which in turn phosphorylate STAT proteins to regulate the expression of inflammation-related genes. Therefore, blocking the JAK-STAT pathway can simultaneously inhibit the signal transduction of multiple pathogenic cytokines, thereby exerting anti-inflammatory effects. Consequently, Ivarmacitinib-a highly selective JAK1 inhibitor-holds promise for improving the prognosis and quality of life of patients with refractory Behçet's syndrome. This is a multi-center, single-arm trial conducted to evaluate the safety and efficacy of Ivarmacitinib in Behçet's syndrome (BS) . Patients with refractory Behçet's syndrome were enrolled . Patients received Ivarmacitinib for up to 24 weeks, which was added to the glucocorticoid and immunosuppressants. The clinical manifestations, inflammatory indicators, imaging and treatment of patients were recorded by investigators during the follow up.

Interventions

The specific regimen was 4 mg of Ivarmacitinib administered daily for 24 weeks. All patients will undergo 24 weeks of prospective follow-up.
