• Subjects with a history of dihydopyrimidine dehydrogenase (DHPD) deficiency or severe and unexpected reactions to fluropyrimidines.
• Subjects with any previously untreated or concurrent cancer that is distinct in primary site or histology except cervical cancer in-situ, treated basal cell carcinoma, or superficial bladder tumor. Subjects surviving a cancer that was curatively treated and without evidence of disease for more than 3 years before randomization are allowed. All relevant cancer treatments must be completed at least 3 years prior to study entry (i.e., signature date of the informed consent form).
