This single arm study will evaluate the efficacy and safety of PEGASYS (180 micrograms sc weekly) plus ribavirin (1000-1200mg po daily) in treatment-naive Latino patients versus non-Latino Caucasian patients with chronic hepatitis C- genotype 1. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ patients.
