Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
