Eligibility Criteria
You may qualify if:
- Male or female, at least 18 years of age and no older than 65 years with compensated chronic HCV infection based on a history of positive serum anti-HCV antibody and/or HCV RNA
- Diagnosed with HCV Genotype 1, 4, 5 or 6 as determined during the screening visit
- The starting doses in the initial treatment must have been 1.5 μg/kg/week PEG-Intron or 180 μg/week Pegasys, and 1000/1200 mg/day ribavirin based on body weight. Patients must have been at least 80% compliant during the initial peginterferon/ribavirin therapy, per patient account.
- Liver biopsy indicating F0-F4 must be performed within 3 years prior to screening. Documentation of the results of the biopsy must be available. If documentation is not available, a liver biopsy must be performed during the screening period. (A maximum of 10 patients in each of the three treatment groups will be patients with a fibrosis score of F4)
- Documented partial response after 12 weeks of treatment as a therapy-naive patient with one course of peginterferon alfa-2a (PEGASYS) and Ribavirin or peginterferon alfa-2b (Peg-INTRON) and Ribavirin
You may not qualify if:
- Detectable HCV RNA after 12 weeks if initial peginterferon alfa/ribavirin therapy and \<2 log decrease in HCV RNA at Week 12 from baseline.
- HCV Genotype 2 or 3
- Severe neuropsychiatric disorder.
- History or clinical manifestations of significant metabolic, hematological, pulmonary, ischemic heart disease, significant or unstable heart disease, gastrointestinal, neurological, renal, urological, endocrine, ophthalmologic disorders including severe retinopathy, or immune-mediated disease.
- Known HIV infection or positive HIV at screening.
- Pregnant or breast-feeding patients.
- Underlying autoimmune disease
