Eligibility criteria:

        Inclusion Criteria:

        The subject must meet ALL of the criteria listed below for entry into the study:

          -  Hemoglobin >= 11 g/dL (females); >= 12 g/dL (males)

          -  Platelet count >= 100,000/mm^3

          -  Neutrophil count >= 1,500/mm^3

          -  Adult male or female chronic hepatitis C (CHC) patients (HCV-RNA-positive in serum)
             with compensated liver disease (Child-Pugh Score <7) and indication for treatment
             according on current consensus guidelines (1. NIH Consensus Conference on the
             Management of Hepatitis C, 2002; 2. German Consensus Conference on Hepatitis B and C,
             published in Z Gastro 2004; 42 (8): 677-730).

          -  >= 18 to =< 70 years of age

          -  At least one abnormal ALT value in the last year

          -  HCV genotype 2 or 3

          -  Not previously treated with any interferon or ribavirin alone or in combination

          -  TSH level must be within normal limits

          -  At the Screen Visit, glucose must be 70-140 mg/dL. Results between 116-140 mg/dL
             require repeat fasting glucose to be less than140 mg/dL and HbA1C less than or equal
             to 8.5%. HbA1C must be less than or equal to 8.5% in diabetic subjects (whether on
             medication or diet controlled).

          -  Female subjects cannot be pregnant or breastfeeding and must be either postmenopausal,
             surgically sterile or using 2 methods of birth control. While abstinence from sexual
             activity is the only certain method to prevent pregnancy, female patients of
             childbearing potential who are or who anticipate the possibility of becoming sexually
             active with a male partner must use a combination of the following 2 methods:
             (1)contraceptive pill or IUD or depot hormonal preparation (ring, injection implant);
             and (2) a barrier method of contraception such as diaphragm, sponge with spermicide,
             condom, or a method of birth control considered acceptable by the study physician.
             Contraceptive measures will be reviewed with female subjects at each visit. Dual
             methods of contraception must be used for 6 months after treatment discontinuation.

          -  Sexually active male subjects must be practicing acceptable methods of contraception
             (vasectomy, use of condom plus spermicide, monogamous relationship with a female
             partner who practices an acceptable method of contraception) during the treatment
             period and for 7 months after stopping treatment

          -  Subjects must be willing to give written informed consent and able to adhere to dosing
             and visit schedules.

          -  Confirmation by the principal investigator or a sub-investigator that sexually active
             females of childbearing potential are practicing adequate contraception.

          -  A serum pregnancy test obtained at Screen Visit prior to the initiation of treatment
             must be negative

          -  Confirmation by the principal investigator or a sub-investigator that sexually active
             male subjects are practicing a method of contraception considered acceptable
             (vasectomy, condom plus spermicide, plus relationship with a female partner who
             practices an acceptable method of contraception). Contraception must be used during
             the treatment period and for seven months (or 6 months, according to local label)
             after the completion of therapy, including condom use by male subjects with pregnant
             partners.

          -  For subjects with a history of hypertension or diabetes, written clearance from an
             ophthalmologist has to be obtained prior to treatment start

        Exclusion Criteria:

          -  Patients younger than 18 years

          -  Patients older than 70 years of age.

          -  Patients with severe renal dysfunction or creatinine clearance < 50 mL/min must not be
             treated with PEG-Intron -Rebetol

          -  Pregnant women, women who plan to become pregnant, male subjects whose partner wants
             to become pregnant, and breastfeeding women.

          -  Subjects with organ transplants, except for corneal or hair transplant.

          -  Any known preexisting medical condition that could interfere with the subject's
             participation in and completion of study, such as:

               -  Preexisting psychiatric condition, especially moderate to severe depression, or a
                  history of severe psychiatric disorder, such as psychosis, suicidal ideation, or
                  suicide attempts. Severe depression includes the following: hospitalization for
                  depression; electroconvulsive therapy for depression; or depression causing a
                  prolonged absence from work or significantly altering daily functions. Subjects
                  with mild depression may be considered for entry into the study provided that a
                  pre-treatment assessment demonstrates that the subject's emotional status is
                  clinically stable, in which case a management plan must be formulated for the
                  subject; this management plan will become a part of the subject's medical record.

                  requiring medication.

                  erythematosus, autoimmune hemolytic anemia, scleroderma, severe psoriasis)

               -  Clinical gout

          -  Subject is or was a substance abuser, such as alcohol (80 gm/day or more), methadone,

             subject must have abstained and agree to abstain from using any of the above for at
             least 6 months. Subjects treated with buprenorphine (Subutex) who have been stable for
             6 months may be included

          -  Any other condition that, in the investigator's opinion, could determine that
             subject's participation in the study is not indicated or could interfere with the
             subject's participation in and completion of study.
