Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the efficacy and safety of telaprevir in combination with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV) in treatment-experienced Black/African American and non-Black/African American participants with Genotype 1 Chronic Hepatitis C (CHC), who have not achieved a sustained viral response with a prior course of interferon-based therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-arm, open-label, multicenter study of treatment-experienced participants with Genotype 1 CHC, who self-identified as Black/African American (Group A) or who did not self-identify as Black/African American (Group B). Participants did not achieve a sustained virologic response 24 weeks after at least 1 prior course of Peg-IFN-alfa-2a/RBV therapy of standard duration, and have 1 of the following viral responses:

* Prior relapse: Participant had a documented undetectable hepatitis C virus ribonucleic acid (HCV RNA) level at the planned end of treatment of at least 42 weeks duration (HCV RNA evaluated anytime between 3 weeks before and 6 weeks after the last dose of Peg IFN-alfa-2a or RBV).
* Prior null response: Participant had a \<2-log10 decrease in HCV RNA at 12 weeks, during prior Peg IFN-alfa-2a/RBV treatment, but never achieved undetectable HCV RNA while on treatment.
* Prior partial response: Participant had a \>=2-log10 decrease in HCV RNA at 12 weeks, during prior Peg IFN-alfa-2a/RBV treatment, but never achieved undetectable HCV RNA while on treatment.
