Where are we at with PD-1 agonism?
Promising novel mechanisms of action always create excitement, but the immune checkpoint PD-1 has cemented itself in the news far more than most. This fame is primarily from therapeutic inhibition in cancer and rheumatological inflammatory sequelae that emerge, but invoking the inverse and using PD-1 agonism to treat classical autoimmunity has subsequently been making its own mark. Given the evident plausibility, how do we feel about invoking the opposite and agonising PD-1 in classical autoimmunity?

Why are vaccine Abs maintained after CAR-T
-depletion of pathogenic #Abs are dampened/eliminated
Clonal repetoire expansion
Remission=naive B cell pop'n
Reset immune system sparing memory cells
vs ?not all pathogenic cells eliminated in tissue

CAR T
Which cells to target
What patients & what disease
When is right time
In vivo (new) ex vivo
Premeds immune suppression
What to use, ?if anything
Cons
Is it safe
?long term effectiveness
What is failure rate
ICANs and other side effects

Needle in a haystack
What T cell to target for #autoimmune diseases
T cell repetoires (TCR) not all are sequenced and many can exist to present antigens
Diff scales of approaches
Implications CAR-T
CD19
CD20
BCMA
Treg
HLAB27
etc!

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.

So what's been tried for ICANS, knowing that it's unlikely that one therapy will fix all of it?

Toxicity is the big question about CAR-T in RA - what did the CRS/ICANS profile look like in this German ph1 in RA?
Pretty good so far - but obviously will be under enormous scrutiny when we are looking at diseases with good existing therapies

🔹DORIS remission: 5 (wk24), 6 (wk36–48)
🔹Residual proteinuria (n=4); renal bx (n=3) showed resolved IC deposits & inflammation
🔹CRS Grade 1 (n=6); no ICANS
