1 giugno 2015 aggiornato da: Vertex Pharmaceuticals Incorporated

A 2-Part, Open Label Study of Telaprevir in Combination With Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) in Subjects Chronically Infected With Genotype 1 Hepatitis C Virus Following Liver Transplantation

To assess efficacy of telaprevir, pegylated interferon alfa-2a (Peg-IFN-alfa-2a), and ribavirin (RBV) for hepatitis C virus (HCV) in a 48-week total treatment duration regimen following liver transplantation.
