Percentage of Participants With Sustained Virologic Response (SVR)
Časové okno: 24 weeks after completion of study treatment (up to Week 72 for "Peg-IFN-Alpha-2A+Ribavirin - 48 Weeks" arm and up to Week 96 for "Peg-IFN-Alpha-2A+Ribavirin - 72 Weeks" arm)
|
SVR was defined as having un-detectable hepatitis C virus (HCV) ribonucleic acid (RNA) levels 24 weeks after completion of study treatment.
HCV RNA levels were measured using Roche COBAS AMPLICOR HCV Test (limit of detection: 50 International Units per milliliter [IU/mL]).
Participants with detectable HCV RNA or without measurement at the end of the 24 week after completion of study treatment were considered as non-responders.
