This was a randomized, multi-center, partially placebo-controlled Phase IV study to compare the efficacy and tolerability of a 48-week combined therapy with pegylated interferon alpha-2a, ribavirin and amantadine sulphate versus placebo in untreated patients with chronic hepatitis C virus-genotype-1-infection. The hypothesis was that there will be an increase in sustained response rate for triple therapy compared to current standard treatment.
Hepatitis C, Chronic
Drug: Amantadine sulphate (in addition to standard treatment)
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Primary Purpose: Treatment
||Randomized, Multi-Center, Partially Placebo-Controlled Phase IV-Study to Compare Efficacy and Tolerability of 48-Week Combined Therapy With Peginterferon Alfa-2a, Ribavirin and Amantadine Sulphate Versus Placebo in Untreated Patients With Chronic Hepatitis C Virus-Genotype-1-Infection
Primary Outcome Measures:
- Proof that peginterferon alfa-2a, ribavirin and amantadine sulphate over a period of 50 weeks improves the permanent virological efficacy by more than 10% compared to peginterferon alfa-2a and ribavirin
Secondary Outcome Measures:
- Verification of the initial virological efficacy up to week 12, defined as negative HCV-RNA test results by means of quantitative proof methods, e.g. Roche AmplicorTM HCV Monitor v.2.0 (sensitivity <600 IE/ml)
- Biochemical efficacy, defined by the serum GPT values 24 weeks after the end of the therapy
- Virological efficacy, measured on the basis of the HCV-RNA values at the end of the therapy
- Biochemical efficacy defined by the serum GPT values at the end of the therapy
| Estimated Enrollment:
| Study Start Date:
| Estimated Study Completion Date:
- Proof that a triple-therapy (peginterferon alfa-2a, ribavirin and amantadine sulphate) dispensed over a period of 50 weeks, improves the permanent virological efficacy by more than 10% as compared to a combination therapy with peginterferon alpha-2a and ribavirin, defined as negative HCV-RNA result obtained by a molecular verification method (e.g. Roche AmplicorTM HCV, v.2.0, sensitivity <50 IE/ml) 24 weeks after the end of the therapy.
- Verification of the initial virological efficacy up to week 12, defined as negative HCV-RNA test results by means of quantitative proof methods, e.g. Roche AmplicorTM HCV Monitor v.2.0 (sensitivity <600 IE/ml).
- Biochemical efficacy, defined by the serum GPT values 24 weeks after the end of the therapy.
- Virological efficacy, measured on the basis of the HCV-RNA values at the end of the therapy.
- Biochemical efficacy defined by the serum GPT values at the end of the therapy.
|Ages Eligible for Study:
||18 Years to 70 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Female and male subjects over 18 years of age and below 70 years of age
- Serological indication of chronic hepatitis C infection with positive anti-HCV test and serum HCV-RNA quantification >600 IE/ml by means of quantitative proof methods, e.g. Roche AmplicorTM HCV Monitor test, v.2.0.
- Untreated patients with HCV-induced chronic infection.
- Indication of a genotype HCV-1 on the basis of the reverse hybridizing assay Inno LiPA from Bayer Versant (Innogenetics).
- Increased GPT serum level on at least one determination date within the 56-day screening phase prior to start of administration of study medication.
- Histological identification of inflammatory activity in the liver, with or without an indication of compensated cirrhosis, during the 24 months prior to start of the study.
- Compensated liver disease (Child-Pugh Grade A).
- Negative urine or serum pregnancy test in fertile female subjects within 24 hours before taking the first dose of study medication.
- During the administration of study medication and for 24 weeks after the treatment has stopped, patients must apply two approved contraception methods, one of which must have a barrier effect on the male, e.g. condom.
