Interferon-Gamma With Interferon Alpha and Ribavirin for Hepatitis C Non-Responders
This study is currently recruiting participants.
Verified by Aga Khan University, September 2007
First Received: October 2, 2007   No Changes Posted
Sponsor: Aga Khan University
Information provided by: Aga Khan University
ClinicalTrials.gov Identifier: NCT00538811
  Purpose

When administered simultaneously, interferon-alpha 2b + interferon-gamma result in dramatic antiviral synergy.Ribavirin has shown to enhance interferon-gamma levels in patients with chronic hepatitis C treated with interferon-alpha. Enhancement of immune responses, especially those related to type-1 T helper cell activity, may contribute to better efficacy in combining ribavirin with IFN-alpha for treatment of chronic hepatitis C. The aim of the present study is to evaluate the efficacy and safety of a triple regimen, a combination treatment with Interferon gamma, Interferon alfa-2b plus Ribavirin in patients who have not previously responded to interferon alpha in combination of ribavirin.
