• measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension(histological confirmation of adenocarcinoma of the colon or rectum.

ECOG performance status of 0, 1, or 2 Estimated life expectancy of at least 12 weeks.

• chemotherapy prior to the diagnosis of metastatic disease. The chemotherapy regimen must not have included oxaliplatin or bevacizumab. No prior therapy for metastatic disease is permitted.
• Evidence of adequate organ function, including:
• Evidence of adequate hepatic function,
• Evidence of adequate renal function INR 18 yrs.

Exclusion Criteria
