Pharmacology
KRAS G12C inhibitor; sotorasib forms an irreversible, covalent bond with the unique cysteine of KRAS G12C, locking the protein in an inactive state that prevents downstream signaling without affecting wild-type KRAS, thereby blocking tumor cell growth and promoting apoptosis in KRAS G12C tumor cell lines.
LONSURF combines trifluridine, a thymidine-based nucleoside analog that is incorporated into DNA to interfere with DNA synthesis and inhibit cell proliferation, and tipiracil, a thymidine phosphorylase inhibitor that increases trifluridine systemic exposure by blocking its primary metabolic pathway.
