  • Anti-HCV antibody positive.
  • Plasma HCV RNA greater than 10,000 copies/mL.
  • Prior liver biopsy indicating chronic hepatitis.
  • WBC count less than or equal to upper limit of normal.
  • Absolute neutrophil count in normal range for the laboratory.
  • Platelet count greater than 130,000 cells/mm³.
  • Hemoglobin concentration greater than or equal to 11 g/dL.
  • PT in the normal range for the laboratory.
  • Normal aPTT.
  • Bilirubin in the normal range unless due to documented Gilbert's disease.
  • Serum creatinine less than or equal to 1.5 times the upper limit of the normal range.
  • Urinalysis showing no evidence of infection or active renal disease (e.g., proteinuria).
  • Subjects must be able to adhere to the visit schedule set forth in this protocol.
  • Written informed consent prior to the performance of any study related procedures.

Exclusion Criteria:

Patients with any of the following criteria during screening will not be eligible:

  • Human immunodeficiency virus (HIV) infection (Western immunoblot confirmed presence of anti-HIV antibodies or detection of HIV RNA in blood).
  • Chronic hepatitis B virus (HBV) infection (HBV surface antigen or DNA in blood).
  • Antiviral therapy for HCV within 3 months.
  • Immunomodulatory therapy (e.g., systemic corticosteriods or interferon) within 3 months.
  • Advanced or decompensated liver disease (e.g., history of bleeding varices, spontaneous hepatic encephalopathy, ascites) of any etiology such as alcohol, drug, obesity, or hemochromatosis.
  • ALT greater than 5x ULN.
  • Histologic evidence of cirrhosis.
  • Presence of an underlying disease state associated with active bleeding.
  • Undergoing therapeutic anticoagulation with heparin or warfarin.
  • Presence of any other active infection requiring therapy.
  • Presence of malignancy.
  • Presence or history of any significant medical illness that might interfere with this study.
  • Receipt of an investigational new drug, biological or therapeutic device within 30 days of study entry.
  • Alcohol or drug abuse requiring medical intervention within 2 years.
  • History of non-compliance with prescribed medical care.
  • Limited mental capacity or language skills to the extent simple instructions cannot be followed or information regarding adverse events cannot be provided
