Abstract

Blockade of the proangiogenic vascular endothelial growth factor (VEGF) and inhibition of matrix metalloproteinases (MMP) are promising novel treatment strategies for cancer. This study assessed the effects of a neutralizing anti-VEGF antibody (A4.6.1) and a MMP inhibitor (BB-94) on pancreatic cancer (PaCa) in vivo in an orthotopic nude mouse model. Monotherapy with either A4.6.1 and BB-94 significantly reduced tumor size, metastatic spread, and microvessel density in PaCa derived from two cell lines (HPAF-2, AsPC-1), thereby increasing survival. Combined VEGF blockade and MMP inhibition elicited additive effects in tumors derived from moderately differentiated HPAF-2 cells. This study adds further evidence for the therapeutic potential of antiangiogenic VEGF blockade and MMP inhibition in experimental PaCa.
