4/ Implications: 🔹Demonstrates feasibility of gene-editing intracellular checkpoints to overcome T cell exhaustion in solid tumors 🔹May be particularly promising cold tumor phenotypes resistant to PD-1 blockade 🔹First step toward "designer TILs" for refractory cancers

Clinical outcomes: 🔹1 pt with MSI-stable, PD-1 refractory CRC achieved CR lasting >21 months. 🔸3 pts had SD with tumor shrinkage (per RECIST v1.1). 🔹Persistence of edited T cell clones detected by bulk and scRNAseq post-infusion.

BASICS: 🔸13 pts treated after lymphodepleting chemo (cyclophosphamide/fludarabine). 🔹Infused with autologous CRISPR-edited TILs (median CISH KO 94%). 🔸No CRS, neurotoxicity, GVHD, or serious gene editing-related AEs observed.

1/ 🚨 First-in-human study of CRISPR-Cas9-edited TILs targeting the intracellular checkpoint CISH in metastatic CRC, led by my friend Dr. Emil Lou @cancerassassin1.bsky.social, presented at #AACR24 thelancet.com/journals/lan... #oncology #crc Key findings from this landmark phase 1 trial 🧵:

Targeting the intracellular immune checkpoint CISH with CRISPR-Cas9-edited T cells in patients with metastatic colorectal cancer: a first-in-human, single-centre, phase 1 trial
These results support the safety and potential antitumour activity of inhibiting the immune checkpoint CISH through the administration of neoantigen-reactive CISH-knockout TILs, with implications for ...
