Clinical Trial Name - Study on Chronic Hepatitis C Treatment With Interferon Alpha, Ribavirin and Amantadine in Naive Pa
| Original Study ID : CIRA-study |
| NCT ID : NCT00146016 |
| Brief Title : Study on Chronic Hepatitis C Treatment With Interferon Alpha, Ribavirin and Amantadine in Naive Patients |
| Official Title : Study on Chronic Hepatitis C Treatment With Interferon Alpha, Ribavirin and Amantadine in Naive Patients |
| Brief Summary : - Adding Amantadine to standard anti-viral treatment can improve sustained response rates in patients with chronic hepatitis C |
| Source : UMC Utrecht |
| Detailed Description : 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. |
