  Purpose

Interleukin 29 (IL-29) is a substance that is produced in the body to help fight viral infections. The purpose of this study is to evaluate the safety and antiviral effects of several different doses of PEG-rIL-29 (a man-made form of IL-29) when it is given in combination with daily oral doses of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease.

Detailed Description:

PEG-rIL-29 (also known as PEG-interferon lambda) is a unique Type III interferon molecule that has demonstrated antiviral activity when administered weekly for 4 weeks to treatment-relapsed and treatment-naive subjects with genotype 1 hepatitis C virus (HCV) infection. Because PEG-rIL-29 binds to a unique receptor with a more limited distribution than the receptor for interferon (IFN)-α, it may have the potential to treat HCV without some of the treatment-limiting side effects associated with IFN-α-based therapies. The purpose of this Phase 2a/b randomized, controlled, multicenter study is to compare the safety and efficacy of PEG-rIL-29 and peginterferon alfa-2a, both administered subcutaneously weekly for up to 48 weeks in combination with daily oral ribavirin, in treatment-naive subjects with chronic genotype 1, 2, 3, or 4 HCV infection. The initial part of the study (Phase 2a) will be conducted as an open-label study; the second part of the study (Phase 2b) will be conducted as a blinded study. The above information provided in this listing is specific to the Phase 2b portion of the study. In addition, two small open-label substudies will be conducted to evaluate the efficacy of 24-week treatment with PEG-rIL-29 and ribavirin in subjects with HCV genotype 1 who have a particular genetic polymorphism associated with favorable response (n=60) and to evaluate the efficacy of 16-week treatment with PEG-rIL-29 and ribavirin in subjects with HCV genotype 2 or 3 (n=30).
