In this randomized, cross-over, open label study the correlation of Pegasys (peginterferon alfa-2a) pharmacokinetics after intravenous (iv) and subcutaneous (sc) administration with viral load and viral kinetics will be investigated in patients with chronic hepatitis C genotype 1 who were non-responders to previous standard combination therapy with pegylated interferon and ribavirin. Patients will be randomized to receive either weekly or twice weekly Pegasys iv or sc for 2 weeks, crossing over to the other mode of administration after a washout period of 6 weeks.

Primary Outcome Measures:
  • HCV RNA levels (IU/ml, COBAS TaqMan HCV Test) in correlation with area under the plasma concentration-time curve (AUC) after sc and iv administration [ Time Frame: 11 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

  • Effect of waist to hip ratio on viral response [ Time Frame: 11 months ] [ Designated as safety issue: No ]
  • Incidence of adverse events [ Time Frame: 11 months ] [ Designated as safety issue: No ]
