A Study of Induction Dosing With PEGASYS (Peginterferon Alfa-2a (40KD)) Plus Copegus in Treatment-Naive Patients With Chronic Hepatitis C. - Full Text View

Purpose

This 4 arm study will compare the efficacy and safety of PEGASYS induction and maintenance dosing, versus standard fixed dosing in combination with Copegus,and the efficacy and safety of higher dose versus standard dose Copegus in combination with PEGASYS. Patients with chronic hepatitis C genotype 1 infection of high viral titer, and baseline body weight >=85kg, will be randomized to one of 4 groups, to receive a)PEGASYS 180 micrograms sc weekly plus Copegus 1200mg po daily, b)PEGASYS 180 micrograms sc weekly plus Copegus 1400-1600mg po daily, c)PEGASYS 360 micrograms sc weekly (induction) followed by 180 micrograms sc weekly (maintenance) plus Copegus 1200mg po daily or d)PEGASYS 360 micrograms sc weekly (induction) followed by 180 micrograms sc weekly (maintenance) plus Copegus 1400-1600mg po daily. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
