Definition

An orally available inhibitor of the oncogenic KRAS substitution mutation G12C, with potential antineoplastic activity. Upon oral administration, KRAS G12C inhibitor MK-1084 selectively targets the KRAS G12C mutant and inhibits KRAS G12C-mediated signaling. This may halt proliferation and metastasis in susceptible tumor cells. KRAS, a member of the RAS family of oncogenes, serves an important role in cell signaling, division and differentiation. Mutations of KRAS may induce constitutive signal transduction leading to tumor cell proliferation, invasion, and metastasis.
