KRAS G12C is an oncogenic driver mutation in multiple cancer types

KRAS mutations can play a role in some of the most common cancers, including lung, colorectal, and pancreatic cancers. The KRAS G12C mutation is an oncogenic driver occurring in approximately 13% of non-squamous non-small cell lung cancer (NSCLC), and 1-3% of other solid tumors, such as colorectal cancer.1,2,3

Targeting a unique surface groove on KRASG12C

Amgen is investigating ways to target mutant KRAS. Recent scientific advancements have revealed a possible binding site in the inactive state of KRASG12C. The mutant cysteine resides next to a narrow surface pocket, the P2 pocket, providing a potential binding target for covalent inhibitors, such as sotorasib.4,5,6
