Target Overview
KRAS is a small GTPase that functions as a molecular switch, cycling between GDP-bound and GTP-bound states to regulate downstream effector pathways controlling cellular proliferation and survival1.
KRAS is a major oncogenic driver and the most frequently mutated member of the RAS family in human cancers. Mutations in KRAS are particularly prevalent in pancreatic, colorectal and lung cancers, making it an important therapeutic target2.
A pan-KRAS inhibitor capable of targeting multiple oncogenic KRAS mutant variants could address a broad range of KRAS-driven tumours. Selectivity for KRAS over NRAS and HRAS may enhance the therapeutic window, support broader combination treatment strategies and expand the number of patients who could benefit from therapy3.
Compound Overview
JAB-23E73 is an allosteric pan-KRAS inhibitor designed to target both the GDP-bound “OFF” state and the GTP-bound “ON” state of KRAS. The compound inhibits multiple oncogenic KRAS mutations as well as wild type KRAS, while maintaining selectivity over NRAS and HRAS.4 It is currently being investigated as a potential treatment for KRAS-driven cancers.
