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).
Since the publication of the first data the optimal dosing schedule is investigated
