Idiopathic inflammatory myopathies (IIM) are a heterogenous group of autoimmune conditions with substantial morbidity. EULAR in collaboration with the American College of Rheumatology (ACR) introduced classification criteria for the major subgroups in 2017,1 but there is a need for contemporary real-world data to understand the burden – and well as new ways of assessing disease activity.

Presented at EULAR 2026 London, Brepocitinib dual TYK2/JAK1 inhibitor with successful Phase 3 VALOR trial demonstrating significant improvement in skin and muscle symptoms in dermatomyositis (DM).

Glucocorticoids are the cornerstone of initial vasculitis treatment, used to rapidly control inflammation and protect vital organs. EULAR has recommendations that cover glucocorticoid use in ANCA associated vasculitides (AAV) and large vessel vasculitis, including giant cell arteritis (GCA).1,2 But the evidence base continues to grow about their use – especially over the long term.
