Percentage of Participants With Extended Rapid Virologic Response (eRVR) - Part APrimary· Assessed at Week 4 and Week 12, week 12 reported
eRVR was defined as Hepatitis C virus (HCV) RNA level below the lower limit of quantitation, target not detected at Weeks 4 and 12 of treatment. HCV RNA level was measured using the Roche COBAS® TaqMan HCV Test v.2.0 (lower limit of quantitation =25 IU/mL; limit of detection \~ 10 IU/mL).

The purpose of this study is to determine whether Peginterferon Lambda-1a (Lambda) combined with Ribavirin (RBV) and Telaprevir (TVR) is effective in the treatment of chronic Hepatitis C (CHC) compared to Peginterferon Alfa-2a (alfa-2a) combined with RBV and Telaprevir.
