Methods of treating patients having mutations in the extracellular domain of epidermal growth factor receptor (EGFR) with a combination of three fully human monoclonal anti-EGFR antibodies
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, 1491M, and S492R.
