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 test the safety and antiviral effects of PEG-rIL-29 (a man-made form of IL-29) when it is given either by itself at different doses or in combination with the approved dose of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease or who have relapsed following previous treatment with PEGylated interferon alpha (PEG-IFN-α), or other form of IFN-α, and ribavirin.

Condition Intervention Phase
Hepatitis C, Chronic
Drug: PEGylated recombinant interleukin 29 (PEG-rIL-29)
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Primary Outcome Measures:
  • Adverse events and standard clinical laboratory abnormalities [ Time Frame: Day 59 ]

Secondary Outcome Measures:
  • HCV RNA levels, serum concentrations of PEG-rIL-29, serum beta2-microglobulin (B2M) levels, serum 2'5' oligoadenylate synthetase (OAS) levels, the presence of anti-PEG-rIL-29 antibodies [ Time Frame: Day 59 ]

Enrollment: 56
Study Start Date: December 2007
Study Completion Date: October 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: PEGylated recombinant interleukin 29 (PEG-rIL-29)
    subcutaneous administration either weekly or every other week
    Other Name: PEGylated interferon lambda (PEG-IFN lambda)
Detailed Description:
This is a 3-part study of PEG-rIL-29 in subjects with chronic genotype 1 hepatitis C virus infection who have either received no prior treatment with a PEGylated IFN-α (or other form of IFN-α) or who have relapsed following prior treatment with a PEGylated IFN-α (or other form of IFN-α) and ribavirin. Part 1 of the study will evaluate the safety and tolerability of escalating doses of PEG-rIL-29 when given as a single agent either every other week or weekly over a 4-week period to treatment-relapsed subjects. Part 2 of the study will evaluate dose levels and/or schedules of PEG-rIL-29 in combination with daily oral ribavirin administered over a 4-week period to treatment-relapsed subjects. Part 3 of the study will evaluate dose levels and/or schedules of PEG-rIL-29 in combination with daily oral ribavirin administered over a 4-week period to subjects who have received no prior treatment.

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
