Real-world bimekizumab in SpA/#PsA (BIMPACT, n=223): 76% retention at 12mo, even with 54% having prior IL-17i exposure. Effective after IL-17Ai failure. Oral candidiasis higher in PsA (16.5%) vs SpA (3.3%); led to discontinuation in ~25%. @RheumNow #EULAR2026 POS0798/POS0810

After failure of a first TNFi in axSpA, #OP0235 from ROC-SpA trial found no superiority of switching to an IL-17A inhibitor over cycling to second TNFi. ASAS40 responses at Week 24 similar with both strategies, supporting individualised treatment decisions. #EULAR2026 @RheumNow

Roc-SpA study
Active axSpA dse + inad response to TNFi ➡️switch or cycled
No significant diff in ASDAS40 at wk24 bet IL-17i & 2nd TNFi
Switching to IL-17i not superior to cycling to 2nd TNFi after inad. response to 1st TNFi
Shared decision is key

Biopsy-guided treatment in PsA: match the drug to the tissue pathotype with 68% in LDA/remission vs 48% standard of care at 6 months. In myeloid CD117+ patients, mean DAPSA reduction at 6 months: IL-17i: −13.5, IL-23i: −12.8, TNFi: −7.5. Synovial biopsy with myeloid CD117+

It's unclear whether GLP-1agonists inmpvove PsA from weight loss or other MoA
74 PsA patients on GLP-1RA vs 74 matched controls (BMI + disease activity matched)
After adjusting for BMI change PROs still improve cDAPSA (-0.4/mo) DAPSA (-0.6/mo) and pain but not SJC, TJC or CRP https://t.co/dcaU2jwbKJ

Izokibep IL-17A Affibody PsA
343 pts RCT PBO crossover wk16
52 wks data
ACR50 50–57% ACR70 36–42% PASI100 64% MDA 47–52%
No diff between QW vs Q2W
AE Injection-site reactions, URTIs most common
No new safety signals
Looks like any other IL17Ai to me

Can we intercept PsA?
Retro study 394 PSO pts 17 yrs follow-up 86 PsA
TNFi linked to higher PsA incidence vs IL- MoA
TNFi 45% vs IL-17i 14% vs IL-23i 10% vs IL-12/23i 11%
After adjustment IL-17i HR 0.35 IL-23i HR 0.17
Needs prospective confirmation!

At Week 52 with izokibep in #PsA PASI90: 63–69%; PASI100: 55–64%; MDA: 47–52%. The small-molecule format may enable deeper tissue penetration. Novel anti-IL-17 approach. Abstr#073 @RheumNow #EULAR2026 #Biologics https://t.co/IaJ1gyECZu

Izokibep (novel small IL-17A inhibitor, 18.6 kDa) maintained efficacy to Week 52 in active #PsA with ~50% of patients achieving ACR50 and nearly half reaching MDA. Sustained durable response with no new safety signals Abstr#OP073 @RheumNow #EULAR2026 https://t.co/Y6fTirE886

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

Small interventional synovial biopsy precision medicine study
CD117 high pts n=15 = better response to IL17i or IL23i inhibition vs. TNFi w/
-DAPSA -13.5, -12.8 vs. -7.5 respectively

Nail #PsA, hard to treat and often overlooked. APEX trial: guselkumab achieved 43% ↓ in nail severity score (mNAPSI) vs 16% worsening on placebo at wk 24, plus PASI 100 in ~39% vs 11%. IL-23 inhibition delivering where pts often struggle most. @RheumNow #EULAR2026 POS0471
