Brief Summary

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

\* Adding Amantadine to standard anti-viral treatment can improve sustained response rates in patients with chronic hepatitis C

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CIRA-study is a double blind, placebo controlled, randomised, multicentre study in previously untreated patients suffering from chronic hepatitis C comparing double therapy, consisting of (PEG-)interferon alpha 2b ((PEG)Intron-A®) and ribavirin (Rebetol®), with triple therapy, consisting of (PEG-)interferon alpha 2b, ribavirin and amantadine, for 52 weeks. Follow-up is completed at week 104. 150 Subjects per treatment group will be included. Patients will be stratified before randomisation according to genotype (1 versus non-1). Viral load will not be a discriminating factor.

The aim is to investigate the efficacy of the adjunct amantadine to the currently used combination therapy with interferon alpha and ribavirin.
