Brief Summary:
This is a randomized, multicenter, 2-part, open-label trial of the combination regimen of grazoprevir (GZR \[MK-5172\]; 100mg), uprifosbuvir (UPR \[MK-3682\]; 450 mg) and ruzasvir (RZR \[MK-8408\]; 60 mg) with and without Ribavirin (RBV) in cirrhotic (C) or non-cirrhotic (NC) participants infected with hepatitis C virus (HCV) previously failing a direct-acting antiviral regimen (DAA). The combination regimen, referred to as MK-3682B, will be administered as two fixed-dose combination (FDC) tablets, given once-daily. The study will evaluate the efficacy of MK-3682B with or without RBV as assessed by the proportion of participants achieving Sustained Virologic Response 12 weeks (SVR12) after the end of all study therapy.
Detailed Description:
This trial was divided into Part A and Part B. In Part A, comprised of 4 treatment arms, C or NC participants with HCV genotype (GT) 1 infection previously failing a DAA regimen of either sofosbuvir (SOF)/ledipasvir (LDV) \[Arms 1 and 2\] or elbasvir (EBR)/GZR \[Arms 3 and 4\] were randomized to receive either one of the following: 1) MK-3682B + RBV for 16 weeks \[Arms 1 and 3\]; or 2) MK-3682B for 24 weeks \[Arms 2 and 4\]. Study Part A was completed as planned per study protocol. In Part B, C or NC participants with GT1 through GT6 infection previously failing any all-oral DAA regimen (GT1-6) or SOF/pegylated interferon and ribavirin (PR) regimen (GT 3 only) were to receive MK-3682B for 16 weeks. However, the trial was terminated prior to participant enrollment for study Part B.
Participants in MK-5172-017 (NCT01667081) were eligible for enrollment in the study.
