• Measurable or evaluable disease
• No prior chemotherapy for advanced colorectal cancer
• Prior adjuvant therapy allowed for resected stage II, III, or IV disease with any regimen containing fluorouracil with or without irinotecan or with immunotherapy, provided recurrent disease has been documented
