 Prior to 2012 sustained response occurs in about 40 – 50 % in people with HCV genotype 1 given 48 weeks of treatment. A sustained response is seen in 70 – 80 % of people with HCV genotypes 2 and 3 with 24 weeks of treatment. A sustained response occurs about 65 % in those with genotype 4 after 48 weeks of treatment. The evidence for treatment in genotype 6 disease is sparse and what evidence there is supports 48 weeks of treatment at the same doses used for genotype 1 disease.
