FDA Approves Avastin for Second-Line Treatment of Metastatic Published on Cancer Network (http://www.cancernetwork.com) FDA Approves Avastin for Second-Line Treatment of Metastatic Colon Ca July 01, 2006 | Colorectal Cancer [1] Avastin (bevacizumab, Genentech), in combination with FOLFOX4-oxaliplatin (Eloxatin)/5-FU/leucovorinhas received FDA approval for the second-line treatment of metastatic colorectal cancer. ROCKVILLE, MarylandAvastin (bevacizumab, Genentech), in combination with FOLFOX4-oxaliplatin (Eloxatin)/5-FU/leucovorinhas received FDA approval for the second-line treatment of metastatic colorectal cancer. The Avastin/FOLFOX4 combination was initially approved for the first-line treatment of metastatic colorectal cancer in February 2004. Avastin is a recombinant, humanized, monoclonal IgG1 antibody that binds to human vascular endothelial growth factor (VEGF) and inhibits its biological activity, resulting in antiangiogenesis E3200 Results The drug's new indication is based on a randomized, controlled, multicenter phase III trial (E3200) that enrolled 829 patients with advanced or metastatic colorectal cancer who had previously received irinotecan (Camptosar) and 5-FU as their initial treatment for metastatic disease or as an adjuvant therapy. The open-label, three-arm, active-controlled trial randomized patients to receive Avastin alone, Avastin plus FOLFOX4, or FOLFOX4 alone. Accrual to the Avastin-alone arm was closed after a planned interim analysis found patients in that arm had a decreased survival, compared to those receiving FOLFOX4 alone. In the two arms with full accrual, the Avastin/FOLFOX4 group had a significant 25% reduction in the risk of death, compared with the FOLFOX4-alone arm. This translated into a 33% improvement in overall survival. The median survival for patients receiving the combination therapy was 13.0 months vs 10.8 months for the FOLFOX4-alone arm.
