Among a panel of KRAS mt NSCLC cell lines, avutometinib + everolimus showed synergistic anti-proliferative activity across KRAS G12C, G12V and G12D variants (mean synergy score of ~18). In the H441 KRAS G12V NSCLC xenograft model, there was a significant reduction in tumor volume and increase in survival with the combination of avutometinib and everolimus (87% TGI; 66 days vs 36.5 days in control group) compared to control....We have shown that avutometinib and everolimus induce synergistic anti-tumor effects preclinically...with KRAS mt NSCLC including non-G12C variants.
