Inclusion criteria

  • Liver transplantation performed at least 6 months and up to 5 years prior randomization and due to HCV cirrhosis, with or without pre-transplant hepatocellular carcinoma (HCC) within Milan or UCSF criteria
  • Immunosuppresive regimen based on tacrolimus b.i.d.- (twice or once daily) for at least 6 months prior randomization
  • Diagnosis of HCV genotypes 1 or 4 infection prior to transplantationconfirmed at screening
  • Indication of treatment with Peg-IFN and ribavirin due to histological evidence of chronic HCV infection defined as a fibrosis stage equal or greater than 1 using the Ishak-Knodell scoring system (IK ≥1) in a liver biopsy performed at screening or up to 4 months prior to randomization.

Exclusion criteria

  • Serum creatinine >150 μmol/L (1.6 7 mg/dL) or eGFR < 50 ml/min (4-variable Modification of Diet in Renal Disease [MDRD Cockcroft-Gault formula])
  • Multi-organ transplant recipients
  • Recent episode of steroid-treated acute rejection (AR) within 3 months prior to randomization, or >1 episode of steroid-treated AR in the last 6 months, or any number of steroid-resistant AR episodes in the last 6 months including evidence of chronic rejection or ductopenia
  • Evidence of conditions that could cause graft dysfunction other than HCV infection
  • Patients with signs of decompensated liver disease, defined as presence of ascites, variceal bleeding, encephalopathy or deteriorated hepatic synthetic function (albumin <3.5g/dL or, total direct bilirubin >1.5mg/dL or, INR >1.5)
  • Co-infection with HIV or Hepatitis B (defined as HBsAg-positive) at screening
  • Use of mTOR inhibitors (everolimus or sirolimus) in the 6 months prior to screening
  • Antiviral treatment for HCV administered at any time after liver transplantation
  • Patients on daily doses of corticosteroids higher than 5 mg/day
  • Patients with fibrosing cholestatic hepatitis
  • Patients with current diagnosis of malignancies, including lymphoproliferative disorders
  • Patients with platelet count <70,000/mm3 or neutrophiles <1,500/mm3
  • History of HCC outside Milan criteria based on radiology or UCSF criteria based on analysis of the explant

Treatment and study plan

cyclosporin (Neoral)

Drug

Neoral capsules bid, Doses were to be adjusted as necessary to achieve and maintain recommended C0 (monitoring of trough levels) or C2 concentration 2 hours post dosing) target ranges

tacrolimus (Prograf)

Drug

Tacrolimus capsules bid, doses were adjusted as necessary to achieve and maintain recommended C0 target ranges.

Primary outcomes

  1. Number of Participants Sustained Virological Response (SVR) Following Treatment of Hepatitis C Virus (HCV) Infection With Peg-IFN and Ribavirin in Liver Transplanted Recipients on Maintenance Therapy With Neoral or Tacrolimus

    Time frame: Week 24

    The achievement of SVR, defined as HCV RNA below limit of detection at the end of AV treatment, 24 weeks after end of AV treatment (W24 post). A dichotomous variable (SVR achieved: Yes/No) was computed. A patient was classified as non-responder (SVR not achieved) if HCV RNA was detectable at the completion of antiviral treatment, at W24post, or at any time between W24 and completion of antiviral treatment. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

Secondary outcomes

  1. Number of Events of the Composite Endpoint of Biopsy Proven Acute Rejections (BPAR), Death or Graft Loss and of the Individual Components

    Time frame: Week 80

    Efficacy failure (biopsy proven acute rejection (BPAR), graft loss, or death

  2. Number of Participants With Fibrosis Progression (Increase in Ishak-Knodell (IK) Score by at Least One Point From the Baseline)

    Time frame: Week 80

    Ishak-Knodell Score: 0=No fibrosis; 01=Fibrous expansion of some portal areas, with or without short fibrous septa; 02=Fibrous expansion of most portal areas, with or without short fibrous septa; 03=Fibrous expansion of most portal areas, with occasional portal to portal (P-P) bridging; 04=Fibrous expansion of portal areas, with marked bridging (portal to portal (P-P) as well as portal to central (P-C)); 05=Marked bridging (P-P and/or P-C) with occasional nodules (incomplete cirrhosis); 06=Cirrhosis, probable or definite, Participants showing an increase of Ishak Knodell fibrosis score by at least one level (increase of ≥1)

  3. Number of Participants of Rapid Viral Response (RVR)

    Time frame: Week 4

    RVR defined as non-detectable HCV RNA 4 weeks after initiation of antiviral treatment. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

  4. Number of Participants of Early Viral Response (EVR)

    Time frame: Week 12

    EVR defined as non-detectable HCV RNA or a ≥2 logs reduction of HCV RNA at 12 weeks after initiation of antiviral treatment. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

  5. Number of Participants for the End of Treatment Response (ETR)

    Time frame: Week 80

    ETR defined as non-detectable HCV RNA at the completion of AV treatment. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

  6. Number of Participants of True Non-responder Rate

    Time frame: Week 80

    Defined as failure to achieve at least a 2 log reduction of Hepatitis C virus (HCV) RNA. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

  7. Number of Participants for Relapse Rate

    Time frame: Week 24

    Defined as reappearance of detectable Hepatitis C Virus (HCV) RNA at 24 weeks after completion of antiviral treatment when HCV RNA was undetectable at the end of treatment. The HCV RNA detection limit was <15 IU/ml (<1.18 log IU/ml)

  8. Number of Participants With Dose Reduction or Discontinuation of Antiviral (AV) Therapy Due to Poor Tolerability at Any Time During the Study for Any Reason

    Time frame: Week 80

    Defined as number of patients with dose reduction or discontinuation of AV therapy due to poor tolerability
