versus 24 weeks), patients with chronic infection due to HCV genotypes 1 and 4 generally have less
favorable sustained virologic response rates (40%-60%) than those infected with genotypes 2 and 3
(>80%). To determine the duration of treatment and monitor the response to anti-HCV therapy, HCV
RNA levels in serum are typically measured in patients at 0 (baseline) 4 weeks (rapid virologic
response, RVR), 8 weeks, 12 weeks (early virologic response: EVR), end-of-treatment (24, 28, or 48
weeks depending on HCV genotype and treatment response), and 24 weeks post-treatment (sustained
virologic response: SVR). -The following algorithms are available in Special Instructions:
