AEE788 inhibited the cell growth more effectively than erlotinib in the three NSCLC cell lines examined; In the EGFR-TKI resistant cell line harboring T790M resistant mutation, cell growth inhibition by AEE788 was only mild; In H1975, AEE788 induced significant cell growth inhibition when combined with RAD001 compared to when used alone; This cooperative effect was not seen in the combination of erlotinib with RAD001
