Immune Dimming or Immune Reset in RA: How Far Should We Go?
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.

Risk of Parkinsons? RA patients have 28% lower Parkinson's risk vs general population (HR 0.72); axSpA had HIGHER risk (HR 1.29). Non-TNF biologics in RA reduced PD risk further (HR 0.74). No effect seen in PsA/axSpA. #EULAR2026 Abstr #POS1116 https://t.co/1vZoZGEu5Z

Comorbidities don’t just impact prognosis, remission and treatment in RA- they impact mortality. Comorbidities cannot be treated in a “one size fits all” approach; they should be assessed and managed on an individual basis.

#EULAR2026 LB0009 It’s like opening Pandora’s box! 2 Open Label RCTs Baricitinib vs TNF-i in RA & =>1 VTE risk:
-VTE:Non-inferiority of BARI wasn’t met (in line with JAK profile)
-No increase in MACE/Cancer (opposed to Oral-Surveillance: TOFA & =>1 MACE risk) @RheumNow #EULARBest https://t.co/nNwtJ3LbkD

Abstr LB0003
Off-the-shelf allogeneic NK cell therapy + rituximab in refractory RA, Sjögren disease, and systemic sclerosis. 31 patients. Outpatient administered.
RA at 6 months: 71% ACR50, mean CDAI change −36.8. SSc: 100% rCRISS25 response. SjD: 86% ClinESSDAI responders. https://t.co/60046jgYia

Interesting data on the effect of AB-101 + RTX on refractory RA, SSc and SjD.
Curious about long term results and potential position in tx strategies

CAR-T without the CAR-T risks?
AB-101, an off-the-shelf NK cell therapy + RTX, delivered in refractory RA, Sjögren, and SSc (n=31): RA ACR50 71%, SSc mRSS -9.5, SjD ClinESS DAI -8.6 at 6 mo. Outpatient delivery without CAR-T associated AEs? @RheumNow #EULAR2026 LB0003 https://t.co/xi6ZdLwHcN

#EULAR2026 LB0003 CAR-T is not scalable. In a Phase 2a of off-the-shelf AB-101 allogenic NK + low dose conditioning (Cyclo & Flud) + Rituximab: preliminary efficacy & safety profile in severe-refractory RA (N=15), SjD (11), SSc (5). Longer FU & Comparator is needed @RheumNow https://t.co/gQniufREQC

Baricitinib did not demonstrate non-inferiority w/ TNFi for first VTE in the RA-BRIDGE and RA-BRANCH trials.
Identifying high-risk pts and individualizing tx is paramount.

Abstr LB0009
Baricitinib vs TNFi in RA patients enriched for VTE risk. 3,640 patients. 3.7 years median follow-up.
VTE: HR 1.61 (95% CI 0.97–2.66)
non-inferiority not demonstrated
MACE: HR 1.06 no cardiovascular excess
Serious infections: HR 1.32 (p<0.05)

BARI vs TNFi in VTE-enriched #RA pts (RA-BRIDGE + RA-BRANCH, n=3,640, ~3.7 yrs follow-up): VTE non-inferiority not met (HR 1.61, CI 0.97–2.66).
But absolute rates low (2.5% vs 1.7%) and MACE was similar (HR 1.06). Serious infections ↑ with BARI. @RheumNow #EULAR2026 LB0009

What drives progression to difficult-to-treat RA?
20-year cohort 675pts
-18.8% developed D2T RA
-Younger age, higher HAQ & prior steroid exposure asso w/ D2T RA
-Earlier b/tsDMARD initiation protective
-No diff TNFi vs non-TNFi first-line strategy

Balinatunfib, oral selective TNFR1 inhibitor designed to preserve TNFR2 signalling in RA. Phase 2b trial missed primary ACR20 endpoint, but 200mg QD arm showed signals for higher ACR50, ACR70 and DAS28 low disease activity & reduced IL-6. @RheumNow https://t.co/emxNQy0cPx

#OP0207 #EULAR2026: SUPERFIBRES trial suggests dietary fibre supplementation may enhance MTX response in RA. Inulin improved EULAR responses and Th17/Treg balance over 30 days, with strongest effects seen in MTX-treated patients. Fascinating microbiome-linked signal. @RheumNow https://t.co/nCvZlooamF

#OP0204 #EULAR2026 Shared decision-making in practice! BACH study tested “treat by choice” in RA. Patients preferred oral JAKi over SC TNFi (55% vs 45%)
Importantly, own choice led to higher treatment satisfaction, better drug survival & fewer adverse events. @RheumNow #EULARBest https://t.co/iI1n2OGzqY
