Description

MRTX849 is a KRAS inhibitor developed by Mirati and is currently undergoing trials for KRAS G12C mutant cancers. This mutation makes up >50% of all KRAS mutations.2

The drug AMG-510 is also currently being developed and has the same target.1

Mechanism of action

Normally GTP binds to KRAS, activating the protein and promoting effectors to the MAP kinase pathway.3 GTP is hydrolyzed to GDP, and KRAS is inactivated.2 KRAS G12C mutations impair hydrolysis of GTP, leaving it in the active form.2

MRTX849 inhibits KRAS in these types of cancers.2 This mutation is present in 13% of non small cell lung cancer, 3% of colorectal and appendix cancer, and 1-3% of solid tumors.1
