This study will test the safety and tolerability of HCV Entry Inhibitor ITX 5061 in Liver Transplant Recipients with Hepatitis C infection. The investigators hypothesize that ITX 5061 oral monotherapy will be safe in adults during and after liver transplantation and that therapy will also inhibit HCV infection of newly transplanted livers in adults with prior HCV infection.

All subjects will receive 28 days of ITX 5061 beginning at the time of transplant.

Dosing of ITX 5061 is as follows:

Day of Transplant prior to surgery: ITX 5061 300 mg Day of Transplant following surgery: ITX 5061 300 mg Post-Operative Days 1-6: ITX 5061 300 mg Post-Operative Days 7-27: ITX 5061 150 mg

Subjects will be monitored for HCV RNA levels, HDL cholesterol and ITX 5061 drug concentration levels.

A liver biopsy will be performed at 6 months post-transplant to assess for histological signs of HCV recurrence.

Inclusion Criteria:

• Age 18-72
• Patients accepted onto waiting list for liver transplantation for HCV related liver disease and receiving a deceased donor liver allograft
• HCV RNA (+) at time of listing for transplantation. All HCV genotypes will be eligible
• Patients with HCC and those receiving hepatitis B core (+) donor livers will be eligible
• Standard immunosuppression protocol with tacrolimus, corticosteroid taper, and mycophenolate mofetil

Exclusion Criteria:

• Viral co-infection (HBV/HIV)
• Receipt of a HCV (+) donor allograft
• Patients undergoing retransplantation for recurrent HCV
• Multivisceral transplantation
• Patients receiving anti-viral therapy at the time of LT
• Live donor liver transplantation
