Brief summary

The purpose of this study is to assess the effect of telaprevir on early hepatitis (inflammation of the liver) C virus (HCV) viral kinetics in treatment-naive participants who are chronically (lasting a long time) infected with genotype 2 or 3 HCV.

Detailed description

This is a Phase 2a multicenter (when more than one hospital or medical school team work on a medical research study), partially blinded, randomized (study drug assigned by chance) stratified (arrange in groups for analysis of results e.g., stratify by age, sex, etc.) for genotype, multiple dose study. The trial will consist of Screening period (6 weeks), Treatment period (24 or 26 weeks) and Follow-up period (24 weeks). The Treatment period will include 2 weeks investigational treatment phase and a 24 week standard treatment phase. All the eligible participants who were never treated for HCV will be enrolled for the trial and will receive the investigational treatment regimen to which they have been randomly assigned for 2 weeks. After this in the standard treatment phase participants will receive the standard treatment of care consisting of pegylated interferon (Peg-IFN)-alfa-2a 180 microgram once weekly and ribavirin (RBV) 400 milligram twice per day. Efficacy will primarily be evaluated by HCV viral load quantification. Participant's safety will be monitored throughout the study.

Interventions

DRUGTelaprevir

Telaprevir 750 mg tablet will be administered three times a day orally for 2 weeks.

DRUGPeg-IFN-alfa-2a + Ribavirin (Standard Treatment)

Standard treatment of Peg-IFN-alfa-2a (180 mcg subcutaneous injection, once weekly) and ribavirin (400 mg as oral tablet twice daily) will be administered from Day 15 to Week 24 or 26 in the T2 & PR24 - genotype 2 and 3 group and from Day 1 to Week 24 or 26 in the T2/PR24 - genotype 2 and 3 group.

Median Time to Virological Response (HCV RNA Level < 10 IU/ml)

Virological response was defined as having HCV RNA level less than a particular threshold which is either less than 10 IU/ml (undetectable) or less than 25 IU/ml (unquantifiable).Time to virological response was defined as the number of days from the start of medication intake necessary to go for the first time below the threshold value. The EOT for group T2 & PR24 was 26 weeks and for groups T2/PR24 and Pbo/PR24 was 24 weeks.

Time frame: Baseline up to EOT

Population: The FAS population included all randomly assigned participants who received at least 1 dose of TVR or placebo.

Relapse was defined as confirmed detectable HCV RNA (\>=10 IU/ml) during the follow-up period up to 24 weeks after last medication intake and after previous undetectable HCV RNA (\< 10 IU/ml) at EOT. No relapse was defined as having no confirmed detectable HCV RNA (\>=10 IU/ml) during the follow-up period and after previous undetectable HCV RNA (\< 10 IU/ml) at EOT. Missing follow-up means no HCV RNA measurements during the follow-up period and after previous undetectable HCV RNA (\< 10 IU/ml) at EOT.

Viral breakthrough was defined as an increase in HCV RNA levels by more than 1 log10 in HCV RNA level from the lowest level reached, or a value of HCV RNA \> 100 IU/ml in participants whose HCV RNA had previously become undetectable (\< 10 IU/ml) or unquantifiable (\< 25 IU/ml) during the considered treatment phase. It was considered as confirmed when the criterion for viral breakthrough is fulfilled at two or more consecutive time points or at the last observed time point in case of trial termination.
