Abstract: The invention relates to the field of recombinant antibodies for use in human cancer therapy. More specifically the invention provides the use of an antibody composition with two distinct non-overlapping binding specificities to human EGFR. The antibody composition is effecting in treating cancer following treatment with other anti-EGFR antibodies, whether the cancer shows progression during or following the prior treatment or not. The antibody composition can also be used for repeated treatment of recurrent tumors following first-line therapy with the antibody composition of the invention, as the composition does not lead to selection of resistant tumors. A further therapeutic use is the use of an antibody composition of the invention for treatment of cancer that is resistant to known anti-EGFR antibodies.
