B-cell targeting has moved to the centre of IgG4-related disease treatment, with inebilizumab, a CD19 depleter, as the recent benchmark. At EULAR 2026, INDIGO tested whether the disease can be controlled by switching B cells off rather than depleting them.

Systemic sclerosis is a rare connective tissue disorder characterised by autoimmune features with vascular manifestations, causing fibrosis of the skin and internal organs. EULAR is focused on systemic sclerosis as the rheumatic disease with the highest morbidity and mortality. New data presented at the EULAR 2026 Congress underscore key complications, and offer hope for a possible new therapeutic strategy.

CD19-directed CAR T-cell therapy has rapidly moved into autoimmune disease, driven in large part by striking reports in SLE, where sustained drug-free remission has raised the possibility of a true immune reset. In RA, where multiple effective therapeutic classes already exist, the relevance of such deep immune interventions remains uncertain.

ASAS and the SPARTAN have updated their key classification criteria for axial SpA (axSpA). EULAR has also recently revised their recommendations on the role of imaging in the diagnosis and clinical management of spondyloarthritis (SpA). Both were presented at the EULAR 2026 annual Congress in London.
