1.1. Adults

Direct acting antivirals (DAA) for hepatitis are FDA-indicated for treatment of chronic infections caused by hepatitis C virus (HCV). Individual agents have varying FDA indications and treatment durations based on genotype (1-6), subtype (1a vs. 1b), liver function, HIV co-infection and/or previous treatment history¹.

Table 1 provides DAA information for treatment naïve patients with or without cirrhosis.

Legend:

HCV = hepatitis C virus;
NS5A inhibitors = Nonstructural protein 5A (NS5A) inhibitors
NS3/4A protease inhibitors = Nonstructural protein 3/4A protease inhibitors
† = For HIV/HCV-coinfected patients, a treatment duration of 12 weeks is recommended with compensated cirrhosis (Child-Pugh A) for genotypes 1-4 and genotypes 5 and 6 regardless of liver status
* = 8 weeks of treatment can be considered in treatment naïve genotype 1 patients without cirrhosis who have pretreatment HCV RNA less than 6 million IU/mL
