A study to evaluate the safety and effectiveness of a quadruple drug regimen (VX-222, telaprevir, peginterferon alfa-2a and ribavirin) in treating chronic hepatitis C virus in subjects with cirrhosis who are treatment naive or nonresponders and relapsers to previous Peg-IFN/Ribavirin therapy.

A Multicenter, Open-Label, Phase 2b Pilot Study to Evaluate the Efficacy and Safety of Quadruple Therapy (VX-222, Telaprevir, Peginterferon-Alfa-2 and Ribavirin) in Subjects With Genotype 1 Chronic Hepatitis C With Compensated Cirrhosis

Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the antiviral efficacy of a quadruple drug regimen (VX-222, telaprevir, Peg-IFN and RBV) in subjects with genotype 1 CHC with compensated cirrhosis, who are treatment naive or were nonresponders (partial or null) or relapsers to previous Peg-IFN/RBV therapy.;Secondary Objective: To evaluate the safety and tolerability of the quadruple regimen in subjects with compensated cirrhosis To assess the efficacy of quadruple regimen across interleukin-28B (IL-28B) genotypes To characterize HCV variants in subjects on the quadruple regimen who have treatment failure To characterize the pharmacokinetics (PK) of VX-222 and telaprevir in the quadruple regimen in subjects with compensated cirrhosis;Primary end point(s): The proportion of subjects who have an SVR (i.e., sustain an HCV RNA concentration below the lower limit of quantitation at 12 weeks after last planned dose of treatment (SVR12);Timepoint(s) of evaluation of this end point: 12 weeks

Secondary

MeasureTime frame
Secondary end point(s): -The safety and tolerability as assessed by AEs, vital signs, 12-lead electrocardiograms (ECG), and laboratory assessments (serum chemistry, hematology, and urinalysis) - Proportion of subjects who have an SVR24 weeks after the last planned dose of the study drug (SVR24) - Proportion of subjects who achieve undetectable HCV RNA at Weeks 2,4,8, and 12 and <LLOQ at the end of treatment -Proportion of subjects who have on-treatment virologic failure, defined as subjects who either meet a futility rule or complete assigned treatment duration and have detectable HCV RNA at the end of study drug treatment - Proportion of subjects who relapse at end of treatment - The association of IL-28B genotype with SVR12 - The amino acid sequence of the NS3 and NS5B proteins in subjects who have treatment failure - VX-222, telaprevir, RBV plasma concentrations; and Peg-IFN serum concentrations;Timepoint(s) of evaluation of this end point: up to 52 weeks
