⭐️C-OPTIMISE: Early, active AxSpA on certilozumab (CZP) 200mg q2w x 48w. Then, if remission, randomized to CZP q2w vs q4w vs PBO x 48w ➡️No flare in PBO BUT w/ ↑: *️⃣ASDAS + BASDAI *️⃣CRP + fecal calprotectin Thus, keep some dose of CZP on! Abst#0916 #ACR21 @RheumNow https://t.co/DT8FKHAhr0

What to do if pt on a TNFi develops cancer? Can you safely restart TNFi later? Depends on cancer, timing - how long ago was cancer, Rx and patient preference. Data diff from RABBIT registry vs British bio registry @RheumNow #ACR21 #ACRBest 7S413 Have a look https://t.co/q9SFKlFJzg

Does concomitant SJS affect tx effectiveness in RA? Abst#0839 suggest yes! ➡️RA+SjS have an inferior response to TNFi than RA patients w/o SjS BUT, RA/SJS pts w/ longer RA dz duration & ↑ DAS28 + HAQ-scores. What's your clinical experience with this? #ACR21 @Rheumnow https://t.co/TIc3raMOSJ

A worthwhile point: despite historic concerns, in the modern era TNFi can used safely & well in HIV pts 18y follow-up, all pts high CD4 (their starting criteria: CD4>200, VL <60,000) no reported opportunistic infx good arthritis response #ACR21 ABST0965 @RheumNow @CCalabreseDO https://t.co/5pbRg63ubr

Post-Hoc of ASCORE trial: ➡️RA w/ mod-high dz on SQ ABAtacept as 1st line tx w/ better retention vs receiving it as 2nd line tx independent of b/l duration of dz ➤Do you use ABA as 1st line treatment for RA, when/if insurance allows?

NORD-STAR Trial: outcomes in tx-naïve, early RA pts after 48w of csDMARDs+GC vs bDMARD (ABAtacept, CerToliZumab, or ToCiluZumab)+MTX ➡️ Superior CDAI remission rates w/ ABA+MTX & CZP+MTX but not TCZ+MTX vs csDMARD+GC ➡️Imaging progression low in all Abst#0825 #ACR21 @RheumNow https://t.co/QaFIF4WNEG
