480 STUDY: Phase 2b Study of Locteron Plus Ribavirin to Treat Hepatitis C Virus (HCV)

Inclusion Criteria: * Male and female subjects 18 through 69 years of age, inclusive * Chronic hepatitis C genotype 1 * HCV ribonucleic acid (RNA) level \> 10,000 IU/mL (by RT-PCR) at screening * Creatine clearance ≥ 50 mL/min * Neutrophil count \> 1500 cells/mm3 * Platelet count \> 90,000/mm3 * Hemoglobin \> 12 g/dL for females and \> 13 g/dL for males * Female subjects of child-bearing potential agreeing to use dual methods for contraception * Male subjects with female sexual partners agreeing to use effective birth control methods * Negative serum pregnancy test for women of child-bearing potential * Compensated liver disease defined as INR \< 1.5, conjugated bilirubin \< 1.5 x ULN, serum albumin \> 3.0 g/dL * Histologic evidence of Chronic Hepatitis C (CHC) (inflammation, fibrosis and/or cirrhosis on a standardized histologic grading system) as shown by biopsy within 2 years of screening or agrees to have a liver biopsy performed prior to randomization. Exclusion Criteria: * Prior antiviral treatment for hepatitis C * Co-infection with HIV or hepatitis B virus * Subjects with a body mass index (BMI) above 32 kg/m2 * Current or prior history of clinical hepatic decompensation * Evidence of HCC * Uncontrolled diabetes mellitus as evidenced by HbA1C ≥ 8.5% at screening * Known hypersensitivity to interferon alfa or ribavirin * Chronic liver disease other than HCV * Clinically significant hemoglobinopathy * History of moderate, severe or uncontrolled psychiatric disease including depression and prior suicide attempts * History of immune-mediated disease * Significant renal or neurological disease * Severe degree (\> GOLD stage III) of chronic pulmonary disease (COPD) or active, severe asthma * Subjects with severe cardiac disease * History of significant central nervous system (including CNS trauma) or seizure disorders * Cancer within the last 5 years, or previous cancer with a high risk of recurrence * History of solid organ or bone marrow transplantation * Clinical or laboratory evidence of uncontrolled thyroid disease, e.g., by thyroid stimulating hormone (TSH) level \> 1.2 x upper limit of normal * Clinically significant retinopathy; this needs to have been excluded by an eye exam performed by an ophthalmologist within the last 6 months prior to screening for subjects with hypertension or diabetes mellitus * Drug abuse or alcohol consumption within the last 6 months which, in the opinion of the investigator, may affect study participation or outcome. Subjects in a supervised methadone treatment program on a stable regimen for \> 6 months may be considered * Taken any experimental agent within 12 weeks prior to screening * More than 30 days of systemic immunosuppressive medication to include steroids in doses equivalent to or greater than 10 mg prednisone per day within 30 days prior to screening (inhaled corticosteroids are allowed) * Nursing mother or male partner of pregnant female.
