Inhibitors of the vascular endothelial growth factor receptor

The inhibitors of VEGF-mediated signaling continue to wind their way through extensive preclinical and clinical development paths. Whereas the first phase III trial did not meet its endpoints, one hopes that the others will. As we learn more about the VEGF pathways in the laboratory and the clinic, we can interpret with greater certainty what role these drugs or their successors will have in the treatment of human cancers.
