WHO HCV Guidelines 2014: Recommendations on HCV Treatment All adults and children with chronic HCV infection, including people who inject drugs, should be assessed for antiviral treatment (strong recommendation; moderate quality of evidence) PegIFN + RBV recommended rather than standard nonpegylated IFN with RBV (strong recommendation; moderate quality of evidence) TVR or BOC, in combination with pegIFN/RBV, suggested for GT1 chronic HCV infection rather than pegIFN/RBV alone (conditional recommendation; moderate quality of evidence) Sofosbuvir, in combination with RBV with or without pegIFN (depending on HCV genotype), recommended for GT1-4 HCV infection rather than pegIFN/RBV alone (and rather than no treatment for persons who cannot tolerate IFN) (strong recommendation; high quality of evidence) Simeprevir, in combination with pegIFN/RBV, recommended for GT1b HCV infection and genotype 1a HCV infection without the Q80K polymorphism, rather than pegIFN/RBV alone (strong recommendation; high quality of evidence) WHO 2014.
