Prospective RCT on safety & efficacy of TAC+GC vs. MMF+GC
TAC+GC was comparable to MMF+GC as continuous induction maintenance treatment over 96 wks for LN.
AE rates comparable.
TAC - AKI & tremor
MMF - leucopenia
reassuring data.more tx options.

LB04: Another approach to CAR-T, CD20+/BCMA bispecific CAR-T in refractory proliferative LN:
🔹100% discontinued biologics & IS at follow-up
🔹Renal response ~78%
🔹CRS mostly Grade 1–2 (~70%); ≥Grade 3 AEs = transient & hematologic

Another toxicity signal to watch in the CAR T space: LICATs
Abstract 1537 reports a new immune-related toxicity distinct from CRS or ICANS:
🔹Affects organs prev involved in autoimmune dx: skin (35%) and kidneys (22%)
🔹Mostly mild (Grade 1–2); 3 cases Grade 3

#MTX is NOT the same as TCZ in #GCA in RCT
#TCZ did better
So use an advanced Rx for GCA
ex TCZ, Upa when approved
METOGiA RCT - more relapses in MTX
