Telaprevir user's guide

Abstract

For a decade, standard therapy for patients with genotype 1 chronic HCV (HCV G1) consisted of pegylated interferon (Peg-IFN) alfa-2a or Peg-IFN alfa-2b, combined with ribavirin. Despite the improved efficacy of this therapy over others, the overall sustained virologic response rate in patients with HCV G1 was still low. This article discusses phase I, II, and III trials examining telaprevir's role in treating patients with HCV. We have now entered an era of combination therapy utilizing direct acting anti-virals, the start of which was marked by the FDA approval of HCV protease inhibitors.
