Study of Bevacizumab Combined With Capecitabine and Either Oxaliplatin or Irinotecan as First Course of Treatment for Patients With Colorectal Cancer That Has Spread Beyond the Colon

Randomized Phase II Clinical Trial of Bevacizumab Combined With Capecitabine and Either Oxaliplatin or Irinotecan as First Line Treatment for Metastatic Colorectal Cancer

Bevacizumab is an angiogenesis inhibitor which means it works to stop blood vessel formation in tumors. Without new blood vessels, the growth of a tumor is slowed. Chemotherapy works to kill cancer cells directly. This study is being done to see how colorectal cancer responds to treatment with the combination of bevacizumab and chemotherapy.

Due to greater patient convenience and favorable toxicity profiles, clinical practice has seen an increased use of the combinations of capecitabine with oxaliplatin (CAPOX) and capecitabine with irinotecan (CAPIRI). Given the data documenting the improved efficacy for 5-FU based chemotherapy in combination with bevacizumab, it is important to investigate the potential advantages of adding this agent to regimens containing capecitabine.
