• Bilirubin <1.5 x ULN.
• AST and ALT up to 2 x ULN; except in the presence of liver metastases; up to 5 x ULN.

• Myocardial infarction, stroke or congestive heart failure within the previous 3 months
• History of acute or chronic gastrointestinal bleeding within the previous two years, inflammatory bowel disease, any other abnormal bleeding tendency, or patients at risk of bleeding due to open wounds or planned surgery.
• Uncontrolled infection or serious infection within the previous 4 weeks.
• Clinically significant non-malignant disease.
• Known AIDS-related illness or HIV positive.
• Women who were pregnant, breast feeding, or of childbearing potential in whom pregnancy could not be excluded.
