This study is currently recruiting participants.
Verified by Vertex Pharmaceuticals Incorporated, March 2010
Purpose
The purpose of this study is to determine whether the combination of telaprevir, peginterferon alfa-2a, and ribavirin is safe and effective in treating hepatitis C virus (HCV) infection in subjects who are infected with both HCV and human immunodeficiency virus (HIV).
Study Type: Interventional
Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Safety/Efficacy Study
Official Title: A Phase 2a, 2-Part, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study of Telaprevir in Combination With Peginterferon Alfa-2a (Pegasys) and Ribavirin (Copegus) in Subjects Who Have Chronic HCV-1/HIV-1 Co-Infection and Are Treatment-Naïve for Hepatitis C
