Civacir® Polyclonal Immune Globulin (IgG) to Prevent Hepatitis C Virus (HCV) Recurrence in Liver Transplant Patients.

Hepatocellular Carcinoma Clinical Trial

Official title: A Multi-Center, Randomized, Prospective, Open-Label Phase III Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Hepatitis C Immune Globulin Intravenous (Human), Civacir®, in Orthotopic Liver Transplant Recipients

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;
