FDA approves Zaltrap ( Regeneron/Sanofi) for treatment of metastatic Colorectal Cancer - 05-Aug-2012

The FDA has approved Zaltrap (ziv-aflibercept) from Regeneron/ Sanofi for use in combination with a FOLFIRI (folinic acid, fluorouracil and irinotecan) chemotherapy regimen to treat adults with Colorectal Cancer. Zaltrap is an angiogenesis inhibitor that inhibits the blood supply to tumors. It is intended for patients whose cancer has spread to other parts of the body (metastatic) and whose tumors are resistant to or progressed after an oxaliplatin-containing chemotherapy regimen.

Zaltrap’s safety and effectiveness was evaluated in a randomized clinical study of 1,226 patients with metastatic colorectal cancer Patients who were assigned to receive the Zaltrap plus FOLFIRI combination lived an average of 13.5 months compared to an average of 12 months for those receiving FOLFIRI plus placebo. A reduction in tumor size occurred in 20 percent of patients receiving the Zaltrap plus FOLFIRI combination versus 11 percent for those receiving FOLFIRI plus placebo. In addition, the clinical trial demonstrated an improvement in progression-free survival, or the time a patient lived without the cancer progressing. The progression-free survival for patients receiving the Zaltrap plus FOLFIRI combination was 6.9 months compared with 4.7 months for those receiving FOLFIRI plus placebo.
