Abstract: The human anti-epidermal growth factor receptor (EGFR) monoclonal antibody, panitumumab, represents a significant advance in the treatment of colorectal cancer. The strategy to target this receptor is based on sound cancer biology demonstrating its essential role in colorectal carcinogenesis. Panitumumab, unlike its predecessor, cetuximab, is fully human and thus reduces the incidence of hypersensitivity reactions. But, in several clinical trials, unexpected toxicities have become more apparent, raising concerns of how readily panitumumab can succeed cetuximab. This paper reviews the development of this agent and the pivotal clinical trials that help our understanding of its optimal use in colorectal cancer treatment.
