Condition(s) targeted: Hepatitis C, Chronic

Intervention: Copegus (Drug); Copegus (Drug); peginterferon alfa-2a [Pegasys] (Drug); peginterferon alfa-2a [Pegasys] (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Hoffmann-La Roche

Clinical Trials, Study Director, Affiliation: Hoffmann-La Roche


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.
