Healthy volunteers: no

Brief summary:
The purpose of this study is to assess efficacy of a human monoclonal antibody against Hepatitis C (MBL-HCV1) combined with telaprevir \[part 1: an HCV protease inhibitor\] or sofosbuvir \[part 2: an Hepatitis C virus NS5B polymerase inhibitor\] in a 56 day treatment duration in patients undergoing liver transplantation due to chronic HCV infection. There is an option for extended study treatment through 84 days if viral load is undetectable at day 56.

Detailed description:
Administration of Intravenous infusions of MBL-HCV1 (50mg/kg) human monoclonal antibody during the first 14 days post-transplantation: three infusions on day 0 (1-4 hours prior to the anhepatic phase, during the anhepatic phase, and 4-12 hours post-reperfusion). Daily infusions on days 1 through 7, weekly infusions on day 14 ± 2, day 21 ± 3, and day 28 ± 3, followed by biweekly infusions on day 42 ± 3 and on day 56 ± 3 if criteria for the stopping rule are not met. For those subjects electing extended treatment, the administration of additional infusions on day 70 ± 3 and day 84 ± 3 will be performed. Subjects receive an oral direct-acting antiviral (telaprevir in Part 1 and sofosbuvir in Part 2) starting no earlier than day 3 post-transplant and no later than day 7; dosing continuing through day 56 unless criteria for the stopping rule are met. Subjects who elect to receive extended study treatment for a total of 12 weeks continue telaprevir in Part 1 or sofosbuvir in Part 2 through day 84 ± 3.
