  Purpose

The effects of treatment with different doses of PEGASYS in combination with different doses of ribavirin will be evaluated in patients with CHC genotype 1 who have a high viral titer, body weight greater than 85kg (187lbs) and no prior treatment with interferon. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
