New biomarkers in RA: Who to treat, Who to watch, Who to taper?

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

CAR-T Reaches the Synovium: COMPARE Phase 1 in ACPA-Positive RA

Save

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.

RA-ILD: Screening risk and genetic susceptibility

Save

RA-ILD remains one of the most serious extra-articular manifestations of RA, contributing substantially to morbidity and mortality. Two abstracts presented at EULAR 2026 add important insights into identifying patients at risk for RA-ILD and understanding the genetic mechanisms that may underpin disease development.

Three Abstracts That May Shape the Future of RA Treatment

Save

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.

CAR-T Cell Therapies in Refractory RMD Current therapies for rheumatoid arthritis rely on sustained immunosuppression rather than restoration of immune tolerance, with off-drug remission remaining rare. Recent anecdotal reports suggest that CD19-directed CAR-T cell therapy may https://t.co/lXX5RjEw6a
