Safety and efficacy of a fixed-dose combination regimen of grazoprevir, ruzasvir, and uprifosbuvir with or without ribavirin in participants with and without cirrhosis with chronic hepatitis C virus genotype 1, 2, or 3 infection (C-CREST-1 and C-CREST-2, part B): two randomised, phase 2, open-label trials
Background There is a need for hepatitis C virus (HCV) therapies with excellent efficacy across genotypes and in diverse populations. Part A of the C-CREST-1 and C-CREST-2 trials led to the selection of a three-drug regimen of grazoprevir (MK-5172; an HCV NS3/4A protease inhibitor; 100 mg/day) plus ruzasvir (MK-8408; an NS5A inhibitor; 60 mg/day) plus uprifosbuvir (MK-3682; an HCV NS5B polymerase inhibitor; 450 mg/day). Part B of the studies tested this combination as a single formulation in different treatment durations in a broader population. Methods Part B of these randomised, phase 2, open-label clinical trials enrolled individuals from 15 countries who were chronically infected with H…
Direct-acting antivirals ombitasvir/paritaprevir/rotonavir+dasabuvir with or without ribavirin in hepatitis C virus (HCV) genotype 1-infected treatment-naive or treatment-experienced patients with or without cirrhosis: real-life experience in Lithuania and Latvia
Background: The current international multicentre open-label, uncontrolled, real-world retrospective study aimed at evaluating the effectiveness and safety of ombitasvir / paritaprevir / ritonavir + dasabuvir ± ribavirin (3D therapy) in treatment-naive and treatment-experienced hepatitis C virus (HCV) genotype 1-infected (GT1) patients. Methods: Adult patients with chronic HCV GT1 infection, scheduled for 3D therapy according to therapeutic guidelines, were eligible. Demographic and clinical data were collected retrospectively by reviewing individuals health records. The primary effectiveness endpoint was the sustained virological response at 12 weeks following the end of treatment (SVR12).…
