Sotorasib (AMG-510) is a first-in-class, orally bioavailable, and selective KRAS G12C covalent inhibitor. Sotorasib irreversibly inhibits KRAS G12C by locking it in an inactive GDP-bound state. Sotorasib is the first KRAS G12C inhibitor in clinical development and leads to the regression of KRAS G12C tumors[1][2].
In cellular assays, Sotorasib (AMG-510) covalently modifies KRAS G12C and inhibits KRAS G12C signaling as measured by phosphorylation of ERK1/2 (p-ERK) in all KRAS p.G12C-mutant cell lines[2].Sotorasib (AMG-510; 1-10 μM; 72 hours) also potently impairs cellular viability in both NCI-H358 and MIA PaCa-2 with IC50≈0.006 μM and 0.009 μM, respectively. Non-KRASG12C lines are insensitive to Sotorasib (IC50>7.5 μM)[3].
In preclinical tumor models, Sotorasib (AMG-510) rapidly and irreversibly binds to KRAS G12C, providing durable suppression of the mitogen-activated protein kinase (MAPK) signaling pathway. Sotorasib (orally; once daily) is capable of inducing tumor regression in mouse models of KRAS G12C cancer[3].
