Viral Resistance in Hepatitis C Genotype-1 Infected Patients

Telaprevir activity in treatment-naive patients infected hepatitis C virus genotype 4: a randomized trial.

BACKGROUND This partially blinded, randomized, phase 2a C210 study evaluated the antiviral activity of telaprevir-based regimens in treatment-naive patients with chronic hepatitis C virus (HCV) genotype 4 infection. METHODS Twenty-four patients received telaprevir 750 mg every 8 hours for 15 days (T; n = 8), telaprevir in combination with pegylated interferon alfa-2a and ribavirin (Peg-IFN/RB...

Real-world effectiveness of ledipasvir/sofosbuvir in 4,365 treatment-naive, genotype 1 hepatitis C-infected patients.

UNLABELLED Real-world effectiveness data are needed to inform hepatitis C virus (HCV) treatment decisions. The uptake of ledipasvir/sofosbuvir (LDV/SOF) regimens across health care settings has been rapid, but variations often occur in clinical practice. The aim of this study was to assess sustained virologic response (SVR) of LDV/SOF±ribavirin (RBV) in routine medical practice. This observatio...

Reducing treatment duration in patients infected with hepatitis C genotype 1: any need for further studies?

The recommended treatment duration with pegylated interferon-alpha plus ribavirin for patients infected with hepatitis C virus (HCV) genotype 1 is 48 weeks. Interestingly, a subpopulation of genotype 1 patients experience rapid decreases in HCV RNA levels once treatment is initiated and attain rapid virological response, defined as undetectable HCV RNA at week 4 of therapy. Several studies have...

NS5A inhibitor resistance-associated polymorphisms in Brazilian treatment-naive patients infected with genotype 1 hepatitis C virus.

OBJECTIVES Several promising NS5A protein inhibitors for hepatitis C virus (HCV) treatment, showing good antiviral activity, are currently being evaluated in clinical trials. However, viral breakthroughs associated with resistant variants have been observed, especially in patients infected with HCV-1a. We aimed to evaluate the occurrence of potential resistance mutations in the NS5A gene of HCV...
