Abstract

Methods are provided for targeting cells for depletion, including without limitation cancer cells, in a regimen comprising contacting the targeted cells with a combination of agents, including (i) an agent that blockades CD47 activity; and (ii) an antibody that specifically binds to EGFR. In some embodiments the cancer cells have a mutated form of one or more of KRAS, NRAS or BRAF. The level of depletion of the targeted cell is enhanced relative to a regimen in which a single agent is used; and the effect may be synergistic relative to a regimen in which a single agent is used.
