while she or her partner is participating in this study, she should inform her
treating physician immediately. Men treated or enrolled on this protocol must also
agree to use adequate contraception prior to the study, for the duration of study
participation, and for 90 days after completion of study drug administration.

bladder are not allowed.

hepatitis B surface antigen [Bag] test at screening) or active hepatitis C
- Patients with past HBV infection or resolved HBV infection (defined as the presence of
hepatitis B core antibody (HBcAb) and absence of HBsAg) are eligible. HBV DNA must be
obtained in these patients prior to Cycle 1, Day 1, but detection of HBV DNA in these
patients will not exclude study participation.
- Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase
chain reaction is negative for HCV RNA.

hospitalization for complications of infection, bacteremia, or severe pneumonia

the opinion of the treating investigator, should preclude study entry.
