Abstract

Aflibercept, an intravenously administered anti-VEGF and antiplacental growth factor (PlGF) agent, has recently been approved by the U.S. Food and Drug Administration in combination with 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) for the treatment of patients with metastatic colorectal cancer who have previously received an oxaliplatin-containing chemotherapy regimen. In the phase III VELOUR trial, aflibercept plus FOLFIRI statistically significantly prolonged both progression-free survival (PFS; median PFS for the aflibercept plus FOLFIRI arm was 6.90 vs. 4.67 months for the placebo-plus-FOLFIRI arm) and overall survival (median overall survival for the aflibercept-plus-FOLFIRI arm was 13.50 vs. 12.06 months for the placebo plus FOLFIRI arm), but grade 3 or 4 adverse events were more common with the addition of aflibercept. However, the addition of aflibercept to 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) in the phase II AFFIRM trial of first-line treatment of mCRC failed to improve PFS or response rate. As a decoy VEGF receptor, aflibercept (VEGF-Trap) has binding affinity for VEGF-A, VEGF-B, PlGF-1, and PlGF-2, and this is a mechanism of significant interest. Optimal strategies for incorporating aflibercept into treatment regimens that include other anti-VEGF and cytotoxic chemotherapeutic agents, as well as development of predictive biomarkers for treatment response, have yet to be defined.
