Patients with HCV with undetectable virus after treatment are eligible. Patients with a prior history of HBV are eligible if quantitative polymerase chain reaction (PCR) for HBV DNA is negative. Note that elevated levels of biotin may interfere with viral serology testing.
- Have a serious nonmalignant disease that, in the opinion of the Investigator or the Medical Monitor, could compromise protocol objectives.
