Abstract: The invention relates to new identified mutations in the epidermal growth factor receptor gene, leading to amino acidic changes which highly correlate with the resistance to a therapy regimen comprising cetuximab. The invention includes peptide sequences and primers to detect the mutations, as well as kits for predicting the response of a subject to a therapy regime comprising cetuximab. In particular, the invention is useful in the therapy regimen applicable to metastasic colorectal cancer.

Abstract: Provided herein are methods of treating an epidermal growth factor receptor (EGFR) extracellular domain (ECD) mutant cancer in a human patient by administering to the patient an oligoclonal anti-epidermal growth factor receptor (anti-EGFR) antibody combination (e.g., MM-151, comprising a first monoclonal antibody (P1X), a second monoclonal antibody (P2X), and a third monoclonal antibody (P3X), wherein P1X, P2X and P3X are in a 2:2:1 molar ratio). In one embodiment, the cancer comprises at least one mutation in the extracellular domain of EGFR selected from the group consisting of EGFR R451C, S464L, K467T, G465R, G465E, I491M, and S492R.

Abstract: Isogenic human cell lines comprising at least one mutated cancer allele under the control of the cell line endogenous promoter, which corresponds to the wild-type cancer allele promoter are disclosed, as well as an in vitro process for determining sensitivity/resistance of a patient suffering from a tumor to a pharmacological agent comprising the following steps: a) identifying at least one mutated cancer allele in a tissue affected by a tumor of said patient; b) providing an isogenic human cell line representative of the tissue, wherein the cell line comprises at least the identified mutated cancer allele, which is under the control of the cell line endogenous promoter corresponding to the wild-type cancer allele promoter; c) putting in contact said cell line with the pharmacological agent; d) determining a variation of proliferation, apoptosis or cytotoxicity of the cell line in presence of the pharmacological agent; wherein the variation of proliferation, apoptosis car cytotoxicity indicative of the sensit
