A Study of the Pharmacokinetics And Pharmacodynamics of Intravenously Administered Pegasys (Peginterferon Alfa-2a) in Patients With Chronic Hepatitis C And Previous Non-Response to Pegylated Interferon And Ribavirin Combination Therapy

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01337375

Brief Summary:
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.

Arm Intervention/treatment
Experimental: A/B Drug: peginterferon alfa 2a [Pegasys]
sc weekly

Drug: peginterferon alfa-2a [Pegasys]
iv weekly

Experimental: C/D Drug: peginterferon alfa-2a [Pegasys]
sc twice weekly

Drug: peginterferon alfa-2a [Pegasys]

Secondary Outcome Measures :
  1. Evaluation of predictors of response to i.v. treatment [ Time Frame: 11 months ]
  2. Effect of waist to hip ratio on pharmacokinetics [ Time Frame: 11 months ]
  3. Effect of waist to hip ratio on viral response [ Time Frame: 11 months ]
  4. Incidence of adverse events [ Time Frame: 11 months ]
