Psoriatic Arthritis: EULAR 2026 Recap

Jack Cush, MD

Years of IL-17 vs. IL-23 debate in PsA finally got tested head-to-head: bimekizumab outperformed risankizumab on joint outcomes in the BE BOLD trial, while a GLP-1 combination study suggests weight and metabolic status are active drivers of PsA — not just comorbidities. This recap also digs into early signals that biologic choice may influence whether psoriasis progresses to PsA, and why some well-controlled patients are still in pain.

#TB Infection or reactivation is Psoriasis or Psoriatic Arthritis pts taking IL-23 inhibitors is rare, rare. Literature review showed 34 studies of IL-23i in PsO had no new TB, but 1 case of LTBI reactivation. In 8 IL-23i PsA studies there were NO new TB or LTBI reactivations https://t.co/h0oe3WksK1

#EULAR2026 LB0001 BOLD results in #PsA. First H2H RCT showing superiority of Bimekizumab (IL17A- & F-i) vs Risankizumab (IL-23-i) in primary endpoint, ACR50 49% vs 38% at WK16. The difference was seen from WK4 & sustained to WK24. May help inform choice of Tx @RheumNow #EULARBest https://t.co/s4zbFiepuP

First head-to-head trial to show #PsA joint outcome superiority BE BOLD: Bimekizumab (BKZ; IL-17A/F dual blockade) beat Risankizumab (RZB: IL-23i) on ACR50 at wk 16 (49.1% vs 38.4%, p=0.0078). BKZ also faster: ACR50 at wk 4 already 19.9% vs 7.2%. @RheumNow #EULAR2026 LB0001 https://t.co/YMQCpom5xD

22% of psoriasis patients developed #PsAover 17 years of follow-up. PsA occurred in 44% of TNFi-treated vs only 9–14% of those on IL-23i or IL-12/23i. Time to discuss "preventive biologics" in PsO? Prospective controlled trials are needed Abstr#072 @RheumNow #EULAR2026

In a 17-year real-world psoriasis cohort, patients on IL-17i had 75% lower odds and IL-23i patients had 84% lower odds of developing #PsA vs TNF inhibitors. Is biologic class selection a PsA interception strategy? Prospective controlled trials are needed Abstr#072 @RheumNow https://t.co/jpdZjGK7VV
