Here's a list of #AACR23 abstract titles I compiled last week. Includes all those I could find for the EU bios, plus other important ones, and various that more reflect my personal interest/curiosity.

mentioned
$SGEN $ROG $RHHBY $MRK $NVS $LLY $REGN $AZN

mentioned (cont'd)
$MRUS $AMGN $GMNX $ZLAB $ERAS $AMAM $ABBV $ARVN $CRSP $RVMD $REPL $GSK $IGMS $XNCR $CRBU $HARP $ZYME $BCYC $ABCL $AFMD $ROIV $NKTX $RCUS $INCY $SANA $ALLO $SUMM #Servier #Akeso #ProfoundBio #DaiichiSankyo #HaiheBio #AvistoneBio #Innovent #JianguHengrui
on what I could notice from browsing these ~5700+ titles
* a lot of presentations/assets on YAP/TEAD pathway
* still a lot of thing IL-12, the industry hasn't given up in it (various approaches)
who knew $REGN was evaluating cell therapies? here CAR vs TCR

1780 / 14 - TCR-T and CAR-T cells targeting HLA-A2/MAGEA4 demonstrate differential tumor control, reflecting co-stimulatory signaling requirements
abstractsonline.com/pp8/#!/10828/p…
that one is also very surprising, since $AZN is listed along this Chinese academia CAR-T in solids!

CT097 / 5 - First report of preliminary safety, efficacy, and pharmacokinetics of C-CAR031 (GPC3-specific TGFβRIIDN CAR-T) in patients with advanced HCC
abstractsonline.com/pp8/#!/10828/p…
* Also a lof of FRα-tgting compounds, with a nice list there

* almost absent: former hot IO targets
some #AACR23 abstracts with nice tables:

918 / 1 - Real-world clinical characteristics and treatment (tx) outcomes by co-mutation status in patients (pts) with #KRAS #G12C-mutated NSCLC #STK11 #KEAP1 #TP53

Obviously, Shingrix is the main driver, but Menveo also did well (+ve policy in FR), and immuno-inflammation/respiratory/others thanks to Benlysta & Benlysta. Onco also but that's such a small franchise at GSK.
