MK-3682B-037-00A: Phase 3 Clinical Trial to Study the Efficacy and Safety of the Combination Regimen of MK-3682B (Grazoprevir/Ruzasvir/Uprifosbuvir) in Participants with Chronic Hepatitis C Virus Genotype 3 Infection

Investigator: Anne Luetkemeyer, MD
Sponsor: Merck Sharp & Dohme Corp

Location(s): United States


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.
