Title: A Phase IIa Randomized, Partially Blinded Trial of Telaprevir (VX-950) in Treatment-Naive Subjects With Chronic Genotype 4 Hepatitis C Infection
Brief Summary: The purpose of this study is to evaluate the activity and safety of telaprevir on Hepatitis C Virus (HCV) Genotype 4, alone or in combination with standard therapy, that is, pegylated-interferon-alfa-2a and ribavirin in treatment-naive (never been treated before with antiretroviral therapy) participants.
