TLDR
Sofosbuvir plus ribavirin for 12 weeks may be effective in previously untreated patients with HCV genotype 1, 2, or 3 infection, and the rate of sustained virologic response 24 weeks after therapy is reported.Abstract:
BACKGROUND The standard treatment for hepatitis C virus (HCV) infection is interferon, which is administered subcutaneously and can have troublesome side effects. We evaluated so fos bu vir, an oral nucleotide inhibitor of HCV polymerase, in interferon-sparing and interferon-free regimens for the treatment of HCV infection. METHODSread more

Optimal therapy of genotype-2 chronic hepatitis C: what's new?
TL;DR: The standard of care for the treatment of HCV genotype 2 (HCV‐2) was pegylated interferon alpha plus ribavirin (PEG‐IFN/RBV) at weight‐based doses for a response‐guided duration but the launches of sofosbuvir and daclatasvir in 2014 have resulted in new, better tolerated and shorter treatment.

TL;DR: It is reported that a genetic polymorphism near the IL28B gene, encoding interferon-λ-3 (IFN-α-2a) is associated with an approximately twofold change in response to treatment, both among patients of European ancestry and African-Americans.

TL;DR: Phosphoramidate prodrugs of the 5'-phosphate derivative of the β-d- 2'-deoxy-2'-α-fluoro-2-β-C-methyluridine nucleoside showed significant potency in the HCV subgenomic replicon assay and produced high levels of triphosphates 6 in primary hepatocytes and in the livers of rats, dogs, and monkeys when administered in vivo.

TL;DR: Naturally occurring dominant STAT‐C resistance mutations are common in treatment‐naïve patients infected with HCV genotype 1, and their influence on treatment outcome should be characterized to evaluate possible benefits of drug resistance testing for individual tailoring of drug combinations when treatment options are limited due to previous nonresponse to peginterferon and ribavirin.
