Comments

Targeted immunotherapy-only trial that admits patients with advanced/ metastatic colorectal cancer with a KRAS G12V mutation. For both, MSS and MSI-H patients.
Trial with engineered TCR T-cells.
AFNT-211: cellular therapy; autologous CD4+ and CD8+ T cells engineered to express a HLA-A*11:01-restricted KRAS G12V-specific transgenic T cell receptor (TCR), the wildtype CD8α/β coreceptor, and a FAS-41BB switch receptor (see Helpful Links for Publications).

Prior immunotherapy allowed, as well as other therapies, after a 14 days wash-out period.
No need to exhaust standard of care: patients are allowed if they progressed on or are intolerant of at least one prior line of standard systemic
