Title: A Prospective, Randomized, Open-label Study Evaluating the Viral Kinetics and Pharmacokinetics of Pegasys® Plus Copegus® and PEG-Intron® Plus Rebetol® in Interferon-naïve Patients With Chronic Hepatitis C.
Brief Summary: This study will examine the viral kinetics and pharmacokinetics of Pegasys plus ribavirin and PEG-Intron plus ribavirin in interferon-naive patients with CHC. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
