Here is my summary of what EULAR 2026 is presenting to us in the field of biomarker-driven personalized care in RA.

At the "What Is New in Psoriatic Arthritis" session at EULAR 2026, Professor Dennis McGonagle (Leeds, UK) took the audience on a whirlwind yet compact tour of the field, touching on three themes: the pathophysiology of PsA, individualization of clinical management, and emerging research and future directions.

Treatment-refractory RA is more common than we sometimes admit. Roughly 11% of patients fail multiple b/tsDMARD classes, and for the ACPA-positive subset, rituximab has long been the fallback. It works, but it rarely produces durable disease-free intervals. CD19 CAR T-cell therapy was always going to be the question that followed the SLE data. Until EULAR 2026, that question had no prospective answer. The plenary session changed that.

Our therapeutic armamentarium in RA keeps on growing. New studies and new molecules, new mechanisms of action or new ways of using old drugs are presented every year at conferences. But which are the ones who can have an impact on our practice? Here is my selection of 3 abstracts presented at EULAR 2026 that identify therapeutic strategies that are well worth keeping on our radar.
