The following minimal hematologic and biochemical criteria: Hemoglobin for males and females >11g/dl Absolute Neutrophil count >1500 cells/mm3 Platelets >75'000/mm3 HBs Ag negative. ANA <1:320, and no evidence for autoimmune hepatitis. α-Fetoprotein <50μg/l (when between upper limit of normal and 50μg/l, ultrasonographical exclusion of hepatocellular carcinoma (HCC) is needed). Fasting blood glucose within normal limits, if history of diabetes or hypertension, a pre-therapy ocular examination is indicated. TSH within normal limits or adequately controlled. Negative urine or blood pregnancy test (for women of childbearing potential) documented within the 2-3 week period prior to the first dose of study drug.

Hypersensitivity to study drugs. Participation in any other clinical trial within 30 days of entry into this protocol. Treatment with any investigational drug within 30 days of entry into this protocol. History or evidence of decompensated liver disease (Child-Pugh B/C) and a Child-Pugh score >5. Ascites, coagulopathy, hyperbilirubinemia, hepatic encephalopathy, or hypoalbuminemia and a Child-Pugh score >5 are conditions consistent with decompensated liver disease.

Any known preexisting medical condition that could interfere with the patient's participation in and completion of the study such as: Preexisting psychiatric condition, especially depression, or a history of severe psychiatric disorder, such as major psychosis, suicidal ideation and/or suicidal attempts (based on a mandatory psychiatric advice). CNS trauma or active seizure disorders requiring medication. Significant cardiovascular dysfunction. Poorly controlled diabetes mellitus. Renal dysfunction, i.e. serum creatinine levels >1.5 times upper limit of normal. Autoimmune diseases. Evidence of severe retinopathy (e.g. CMV retinitis, macular degeneration).
