* HBV DNA \< 500 IU/mL obtained within 28 days prior to initiation of study treatment
* received anti-HBV treatment (per local standard of care; e.g., entecavir) for a minimum of 14 days prior to study entry and willingness to continue treatment for the length of the study
* Patients with a history of HCV infection but who are negative for HCV RNA by PCR will be considered non-infected with HCV
