Efficacy and Safety of Grazoprevir (MK-5172), Elbasvir (MK-8742), and Sofosbuvir for Chronic Infection With Hepatitis C Virus Genotypes 1 and 3 (MK-5172-074)

Hepatitis C Clinical Trial

Official title:
A Phase II Open-Label Clinical Trial to Study the Efficacy and Safety of the Combination Regimen of MK-5172, MK-8742, and Sofosbuvir in Treatment-Naïve Subjects With Chronic HCV GT1 or GT3 Infection

Clinical Trial Summary

This is a study of grazoprevir (MK-5172) + elbasvir (MK-8742) and sofosbuvir (SOF) in treatment-naive participants with chronic hepatitis C (HCV) genotype (GT) 1 or GT3. The objective is to determine the proportion of participants achieving sustained virologic response 12 weeks after ending study treatment (SVR12).

Clinical Trial Description

The study is an open-label, single-center, multiple-arm investigation of a fixed-dose combination [FDC] of grazoprevir 100mg + elbasvir 50mg, and SOF 400mg, in treatment-naive participants with chronic HCV GT1 or GT3. The impact of study treatment regimens of varying duration on SVR12 (undetectable HCV ribonucleic acid [RNA] 12 weeks after ending study treatment) in cirrhotic (C) participants and non-cirrhotic (NC) participants will be determined (Part A). Any HCV GT1 participant from study Arms 1-4 in Part A who experienced virologic relapse will be offered retreatment consisting of 12 additional weeks of treatment with MK-5172/MK-8742 + SOF + ribavirin and 24 weeks of follow-up in Part B. ;
