  • At least one alanine aminotransferase level greater than the upper limit of normal between three months and twelve months prior to randomization
  • For the duration of treatment with study drug for all subjects and for the duration of treatment with study drug plus an additional six months for subjects who take ribavirin, attenuation of the potential of the subject to become pregnant, or to impregnate a sexual partner, by either:

    1. the use of an approved contraceptive method (e.g., IUD, oral contraceptive, or double-barrier method), or
    2. definitive exclusion by surgery, radiation, menopause or vasectomy
  • For women of childbearing potential, negative serum Beta HCG pregnancy test within 14 days prior to randomization

Exclusion Criteria:

  • A total white blood cell count of less than 3,000 per mm3
  • An absolute neutrophil count of less than 1,500 per mm3
  • Abnormal thyroid function (Subjects requiring thyroid replacement and who have stable, normal thyroid function may be admitted to the study)
  • History of significant renal dysfunction
  • History of significant or unstable cardiac disease
  • Concurrent alcohol abuse or illicit drug use

  • Positive test for illicit drugs
  • A history of malignancy (except for previously cured squamous cell or basal cell carcinoma)
  • Known hypersensitivity to interferons or ribavirin or related compounds
  • A concurrent diagnosis of depression that has not been stable for at least 60 days prior to randomization
  • Usage of an investigational drug within the 30 days prior to randomization; or the planned usage of an investigational drug other than omega interferon during the course of the current study
  • Prior randomization to this study
  • Any condition which, at the discretion of the investigator, would render an individual an inappropriate candidate for this study
