Hepatitis C future or investigational therapies

Introduction

Overview

Overview

Several investigational drugs are being tested for use in hepatitis C such as danoprevir, asunaprevir, vaniprevir, and ledipasvir among others.

Future Or Investigational Therapies

Future Or Investigational Therapies

Several investigational drugs are being tested for use in hepatitis C. These agents focus on proteins essential for viral replication. The table below summarizes the agents currently being investigated.

Name Alternative Mechanism of Action
Danoprevir[1] RG7227/ITMN-191 Inhibitor of the HCV NS3/4A serine protease
Asunaprevir[2] BMS-650032 Inhibitor of the HCV NS3/4A serine protease
Vaniprevir[3] MK-7009 Inhibitor of the HCV NS3/4A serine protease
Daclatasvir[4] BMS-790052 Inhibitor of the HCV non-structural protein NS5A
Mericitabine[5] RG7128 Inhibitor of the HCV NS5B polymerase
Ledipasvir[6] GS-5885 Inhibitor of the HCV non-structural protein NS5A
Faldaprevir[7] BI-2010335 Protease inhibitor
