The present invention relates to anti-cancer therapeutics. In certain aspects, cancers are treated with a combination of an anti-EGFR agent and an agent that increases the activity of the KLF6 tumor suppressor gene and/or an agent that increases activity of the FOXO1 tumor suppressor gene. In a preferred aspect, the anti-EGFR agent erlotinib a tricyclic agent compound, are used in combination to treat non-small cell lung cancer in a patient with primary or acquired drug resistance to erlotinib, and wherein the tricyclic agent is administered in an amount that does not lead to a substantial central nervous system effect. In additional aspects, the invention relates to compositions and kits useful for treating cancers, methods for screening for compounds that enhance the activity of anti-EGFR agent, and methods for determining whether a patient will respond to anti-EGFR therapy. |
