Hepatitis C virus (HCV) genotype 1 is the most prevalent worldwide. Subtype 1a, compared with 1b, shows lower response rates and higher propensity to select for drug resistance to NS3 and selected NS5A and nonnucleoside NS5B inhibitors. Two distinct clades of subtype 1a have been described.
Is HCV genotype 1a curable?
With PEG/ribavirin treatment alone, genotype 1 HCV used to require the longest duration of treatment with the least likelihood of success. With sofosbuvir, genotype 1
is now curable
in more than 95 percent of people treated for only 12 weeks.

For HCV genotype 1a infected, treatment-naïve patients or patients who do not have cirrhosis, or in whom prior INF and RBV treatment has failed, there are three regimens of comparable efficacy: (1) daily fixed-dose combination of Ledipasvir/Sofosbuvir for 12 weeks,
(2) daily fixed-dose combination of Paritaprevir/
