Brief Summary:
The purpose of this study is to test the safety and efficacy of Civacir® to prevent the recurrence of Hepatitis C Virus (HCV) after liver transplant.

Hepatitis C Infection Viruses Hepatocellular Carcinoma Hepatitis, Viral, Human Liver Cirrhosis Biological: Civacir® 10% Phase 3

Detailed Description:

Civacir® 10%, Hepatitis C Immune Globulin Intravenous (Human) is a high-titer human polyclonal immune globulin (IgG) containing a diversity of antibodies that target and bind the hepatitis C virus (HCV) to prevent infection. Subjects who reduce their viral load to less than 100 IU/ml HCV RNA through up to 24 weeks of antiviral therapy prior to liver transplant are enrolled in the study. There is no requirement to reach undetectable virus prior to transplant as the function of Civacir® is to neutralize any remaining virus in circulation.

Subjects randomized to Civacir® treatment arms receive study drug infusions starting on the day of liver transplant followed by 15 doses over a 10 week period to prevent the recurrence of quantifiable Hepatitis C Virus (HCV) after liver transplant. The study will evaluate dosing arms ranging from 200 mg/kg to 300 mg/kg compared to a control arm. For the primary endpoint, efficacy is defined as persistent viral load suppression maintaining HCV RNA levels below the lower limit of quantitation as determined by central laboratory Polymerase Chain Reaction (PCR) at 22 weeks post-liver transplant and then at 34 weeks post-liver transplant to demonstrate durability of effect.

Arm Intervention/treatment
No Intervention: Observational Control
Subjects who attain HCV RNA <100 IU/ml and are randomized to the control arm will receive standard post-transplant immunosuppressant therapy and be followed for a 34 week period.
Experimental: Civacir® 10% at 200 mg/kg dose
Subjects who attain HCV RNA <100 IU/ml and are randomized to the Civacir 200 mg/kg treatment arm will receive Civacir® before liver transplant, followed by 15 infusions over a 10 week regimen, with standard post-transplant immunosuppressant therapy. Civacir® treated subjects will be followed up to 34 weeks post-transplant.
Biological: Civacir® 10%
The active ingredient is Human Immunoglobulin G (IgG) which is a normal constituent purified from human source plasma containing a diversity of antibodies targeting the Hepatitis C Virus.

Primary Outcome Measures :
  1. Determine the efficacy of Civacir® in preventing post-transplant HCV recurrence at 22 weeks post transplant [ Time Frame: 22 weeks ]
    The primary objective is to assess the effect of administering Civacir® anti-HCV immunoglobulin therapy on prevention of orthotopic liver transplant (OLT) HCV recurrence, as measured by the proportion of subjects with unquantifiable HCV RNA levels at 22 weeks post-OLT, compared to the control group (not treated with Civacir® and considered standard of care).


Secondary Outcome Measures :
  1. Determine the efficacy of Civacir® in preventing post-transplant HCV recurrence at 4 and 34 weeks post transplant [ Time Frame: 34 weeks ]
    Evaluate the proportion of subjects with unquantifiable HCV RNA, as measured quantitatively by PCR at 4 and 34 weeks post-OLT, for assessing the durability of effect.


Other Outcome Measures:
  1. Determine the biochemical response of Civacir® in preventing post-transplant HCV recurrence at 22 and 34 weeks post transplant [ Time Frame: 34 weeks ]
    Evaluate the biochemical response at 22 and 34 weeks post-transplant: the proportions of subjects with normal ALT, AST, total bilirubin and alkaline phosphates at 22 and 34 weeks.

  2. Evaluate the safety of Civacir® in preventing post-transplant HCV recurrence up to 34 weeks post transplant [ Time Frame: 34 weeks ]
    Evaluate the safety of Civacir® in the treatment of subjects with HCV undergoing liver transplantation by the number of adverse events including safety laboratory parameters.

  3. Evaluate the pharmacokinetics of Civacir® up to 34 weeks post transplant [ Time Frame: 34 weeks ]
    Evaluate the pharmacokinetics of Civacir® following intravenous infusion(s).
