#ACR25 Abstr#2695 Inguinal lymph node biopsies pre- and post-OBI, RTX, BLIN & CD19 CAR-T showed complete tissue depletion with CAR-T. B-cells reduced but often incomplete with protein-based depleters; OBI being the best. Still don’t agree with “immune reset” @RheumNow #ACRBest https://t.co/Sq7m9sXlLP

Abstract 2697: Compared to MMF, tacrolimus showed
- similar SRR by week 96 (58.5% vs. 69.2%, OR 0.62; 95% CI 0.29-1.29)
- similar time to renal AE/deaths (HR 0.70; 95% CI 0.37-1.35)
- serious AEs less frequent (12.3% vs. 30.8%)

#2658 In >870k adults with T2DM or obesity, GLP-1 receptor agonists showed no increase in autoimmune or inflammatory disease risk, and were instead linked to lower mortality, heart failure, stroke and dementia. Excellent real-world safety signals. @RheumNow #ACR25

Abstract 2695: Deep dive into B-cell depletion (BCD)
Lymph node biopsy pre/post tx:
🔹 CAR T: complete BCD + disrupted follicular architecture
🔹 RTX, OBI, BLIN: reduced BCD + preserved follicular architecture
✅ Complete LN depletion → drug-free remission

This prospective study from Brazil evaluated the effect of RHZ vax in SSc pts
SSc pts had ⬆️rates of seroconversion
mean titers ⬆️ from BL
Local rxs ⬇️ in SSc pts
Systemic rxns comparable among the 2 grps
interesting data. longterm studies still needed

Autologous CAR-Treg in RA, without any lymphodepletion preRx
Early data from ph1, single dose
Good initial response, stopped RA Rx, but some rebound
Clearly work ongoing but excitement re:
- CAR-Treg
- RA as target dx
- no lymphodepletion

REGULATE RA SBT-77-701
Engineered Treg cell in Refractory RA population
6patients
Safety and tolerability: No DLT, CRS or ICANS
Efficacy
Reduction >50% in TJC and SJC
67% reduction of DAS-CRP >=2
stained up to wk 24
Impressive in pts for whom it works, yet a couple seem to https://t.co/lQAQABPhg0

#ACR25 Abstr#LB23 Phase 1 trial in 5 refractory #RA of SBT777101, a novel autologous CAR-Treg (without the need for lymphodepletion) showed promising efficacy and safety signal. No DLT, CRS or ICANS. Looking forward to larger data and in other RMDs @RheumNow https://t.co/YyGMSHjA3z

#ACR25 Abstr#LB20 At EULAR, data for Phase 3 RCT of Deucravacitinib, Tyk2-i in active #PsA showed ACR20 was met at WK16. Here, data showed sustained response through WK 52 across core domains inc. those who switched PBO->DEU. No major safety assoc. with JAK-i.A few acne @RheumNow https://t.co/tmzQMOtjev

Questions #ACR25 LB20 to Paul Emery on rosnilimab:
Fleischmann: could be induction therapy? (Not intent, but could be)
Choy: Depth of changes with translational data
Tanaka: Safety given peresolimab ph2b here (diff epitope, membrane proximity, targeted depletion PD-1hi)

PD-1 agonist as an induction therapy in refractory RA??
Rosnilimab ph2b:
- still responding 3mo after Rx stopped
- no difference between type of prior b/tsDMARD failure
- safety here looks good *so far*
A lot of cautious excitement in the room for this

A new approach in RA:
Rosnilimab targets & depletes PD-1–high pathogenic T cells, acting upstream of cytokine pathways. In Ph2b, all doses improved DAS28-CRP & ACR responses vs placebo, with durable efficacy & good safety.

#ACR25 Abstr#LB19 New T-cell therapy on the block! In Phase 2b RCT of #RA (~50% b/tsDMARD-IR), Rosnilimab, PD-1 agonist met its endpoint (DAS28-CRP) at WK12. Effective despite type of previous therapy. No safety concern/malignancy/death. To proceed to Phase 3 @RheumNow #ACRBest https://t.co/MecTYMpH0o

We often see patients with MTX lab abnormalities but How frequent is MTX toxicity?
Retrospective study 2500pts

DMARD exposure overall during pregnancy is not associated with severe maternal or neonatal morbidity, in this Ontario cohort.
We’re getting better at finding a balance with DMARDs that is safe for both mother and baby. Blanket resistance is harmful
