• Must have had screening procedures for cancer appropriate for the patient's age and gender, within the last 12 months; or be willing to obtain such screening before randomization

• Women: are not breastfeeding

• Women: nonchildbearing potential (ie, postmenopausal or surgically sterile) or must use a medically accepted contraceptive regimen for at least 60 days before the baseline visit, and agree to continue such use throughout the duration of the study and for 30 days after the final dose of study drug. Women must be given a pregnancy test unless they are at least 2 years postmenopausal or surgically sterile.

• Have any other known medical or psychiatric condition that may compromise participation in the study

• Have a history of prior malignancy (excluding basal or squamous cell cancer of the skin) within the previous 5 years

• Have an unresolved abnormal cancer screening test result before randomization
