BI-0474 is a potent KRASG12C inhibitor with an IC50 value of 7.0 nM for the GDP-KRAS::SOS1 protein-protein interaction. BI-0474 exhibits good anti-proliferative activity against NCI-H358 cells carrying the G12C mutation. BI-0474 also shows good anti-tumour activity in non-small cell lung cancer xenograft models.
BI-0474 (1-10,000 nM; 3 days) shows potent antiproliferative activity of 26 nM on NCI-H358 cells carrying a G12C mutation[1].
BI-0474 (40 mg/kg; i.p.; single daily for 3 days) shows anti-tumor efficacy and pharmacodynamic biomarker modulation in an NCI-H358 cell line-derived non-small cell lung cancer xenograft model[1].
