Angiogenesis is a multistep process that plays a key role in cancer growth and metastases. It is mediated through multiple vascular endothelial growth factor receptors (VEGFRs) and their ligands. The expression of VEGFR-2 is upregulated in tumor endothelial cells, and it is considered to be the primary receptor driving malignant angiogenesis. Ramucirumab (IMC-1121B, LY3009806) is a fully human monoclonal antibody that directly binds to VEGFR-2 with high affinity and specificity. It is also the most recent addition to our armamentarium of anti-angiogenic drugs approved for the treatment of metastatic colorectal cancer (CRC). The aim of this review is to summarize the pre-clinical and clinical development of ramucirumab and discuss its place in the current treatment paradigm for metastatic CRC.
