  Purpose
The results of antiviral therapy in patients with recurrent hepatitis C after liver transplantation are lower than standard. Ribavirin has immune-modulating effects and seems to be crucial to optimize viral treatment. The aim of this multicenter controlled study is to examine the effect of Ribavirin pre-treatment preceding the combination therapy with peginterferon plus ribavirin on the sustained virological response.

Condition Intervention Phase
Hepatitis C Drug: ribavirin pre-treatment Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase 2 Randomized Multicenter Controlled Study of Ribavirin Pre-treatment (8 Weeks) Followed by Standard Therapy With Ribavirin and Pegylated Interferon (48 Weeks) in Transplanted Patients With Recurrence of Chronic Hepatitis C
