Brief Summary

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

This study will evaluate the addition of a higher-dose induction treatment period with peginterferon (PEG-IFN) alfa-2a (Pegasys) and ribavirin prior to standard-dose treatment with PEG-IFN alfa-2a and ribavirin, compared to standard-dose treatment, in treatment-naive participants with CHC, genotype 1 infection.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PEG-IFN alfa-2a+Ribavirin - Induction Treatment

Participants will receive 12 weeks of induction therapy with PEG-IFN alfa-2a (Pegasys), 360 micrograms (mcg) subcutaneous (SC) once weekly, along with ribavirin, 1000 or 1200 milligrams (mg) orally daily in divided doses. Thereafter, the dose of PEG-IFN alfa-2a will be reduced to 180 mcg SC once weekly and the ribavirin dose maintained for the remaining 36 weeks of treatment.

Group Type EXPERIMENTAL

PEG-IFN alfa-2a

Intervention Type DRUG

PEG-IFN alfa-2a will be administered once weekly for 48 weeks, at doses specified in respective arms.

Ribavirin

Intervention Type DRUG

Ribavirin 1000 or 1200 mg orally daily in divided doses, with the dose determined based on body weight, for 48 weeks.

PEG-IFN alfa-2a+Ribavirin - Standard Treatment

Participants will receive 48 weeks of standard therapy with PEG-IFN alfa-2a, 180 mcg SC once weekly, along with ribavirin, 1000 or 1200 mg orally daily in divided doses.

Group Type EXPERIMENTAL

PEG-IFN alfa-2a

Intervention Type DRUG

PEG-IFN alfa-2a will be administered once weekly for 48 weeks, at doses specified in respective arms.

Ribavirin

Intervention Type DRUG

Ribavirin 1000 or 1200 mg orally daily in divided doses, with the dose determined based on body weight, for 48 weeks.

* Compensated liver disease
* Naive to interferon-based therapy for CHC infection

Exclusion Criteria

* Systemic antiviral, antineoplastic, or immunomodulatory treatment within 6 months of study drug
* Coinfection with active hepatitis A or B virus, or with human immunodeficiency virus (HIV)
