To further evaluate the anticancer potential of the combination of OTS514, AMG510 and 5-FU, we treated KRASG12C A549 cells with different combination of drugs and examined the cell death and proliferation…when the three agents were applied together (5-FU + OTS514 + AMG510), an even stronger apoptosis induction and anti-proliferation effects were observed (Figure 8A–C). Therefore, the combinatory usage of 5-FU, OTS514 and AMG510 could potentially produce the optimal anticancer effect against NSCLC with KRASG12C mutation.
