-Summary

By chance the investigators found that iv. silibinin has a potent antiviral effect against the hepatitis C virus. Based on the results of the dose finding study (published) te optima dosing schedule is explored.This study will be evaluate whether the highest active dose given for the optimal time combined with standard of care will result in a sustained virologic response (=cure of hepatitis C).

+Arms and interventions

ArmTypeInterventionsDescription
on treatment nonrespondersExperimentalDrug: Silibininnaive patients with null response to peginterferon/ribavirin at week 12 or partial response at week 24
Nonresponders to previous antiviral combination therapyExperimentalDrug: SilibininNonresponders defined by viral status at weeks 4,12, and 24 of previous peginterferon/ribavirin combination therapy
  • Silibinin (Drug), also known as Silibinin infusions (20 mg/kg/d infused over 2 hours)given for 21 (either Monday -Friday or daily) or 28 days, continuation of antiviral combination therapy: comparison of different dosing schedule of Silibinin infusions (20 mg/kg/d infused over 2 hours) A: 3x5days B: 14 days C: 21 days D: 28 days sequential the infusion duration will be shortened - 2 hours, then 1 hr and then 1/2 hr/infusion
  • Silibinin (Drug): 20 mg/kg Silibinin iv /d /21 days, antiviral combination therapy will be continued
