A Study of the Influence of Ribavirin on the Initial Viral Response in Patients With Chronic Hepatitis C (CHC)
Status: Recruiting
Protocol number: ML19301
Sponsor: Hoffmann-La Roche AG
Company division: Pharmaceutical
Official Scientific Title: Randomized, multicentric, partially double-blinded placebo-controlled phase II study for examining the influence of Ribavirin on the initial virological response with treatment of Peginterferon alfa-2a (40KD) and Ribavirin with a six week pretreatment-phase of Ribavirin/placebo or PEG-Interferon mo
Brief summary: This study will examine the influence of ribavirin on the initial virological response in treatment-naive patients with chronic hepatitis C, genotype 1. Patients will be randomized to one of three treatment groups to receive placebo, ribavirin monotherapy 1000mg to 1200mg po daily or PEGASYS (peginterferon alfa-2a (40KD)) 180 micrograms sc weekly, for 6 weeks. Following the initial 6 weeks, all patients will receive combination therapy with PEGASYS plus ribavirin (COPEGUS) for 12 weeks. If there is an initial virological response after 12 weeks of combination therapy, treatment may be continued for a further 36 weeks. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals. Target sample size is 60.
