Optimal therapy in genotype 4 chronic hepatitis C: finally cured?

Abstract

Optimal therapy for patients with hepatitis C virus (HCV) genotype 4 (HCV-4) infection is changing rapidly, and the possibility of a total cure is near. The standard of care has been combination pegylated interferon (PEG-IFN)-ribavirin (RBV), with modest response rates and considerable adverse events. Since the introduction of sofosbuvir (SOF), simeprevir (SIM), and daclatasvir (DCV), the duration of treatment has been significantly shortened and response rates have increased. The recommended treatment for IFN-eligible patients is PEG-IFN/RBV plus SOF, SIM or DCV. In IFN ineligible patients, the optimal regimen is a 24-week course of SOF/RBV, or a 12-week course of SOF-SIM or SOF-DCV with or without RBV. The pipeline for patients with chronic HCV is highly active. IFN-free combinations with paritaprevir-ombitasvir, SOF-ledipasvir, or DCV-asunaprevir (ASV)-beclabuvir (BMS-791325) for 12 weeks or less with close to 100% cure rates will soon become the optimal therapy.
