Summary:

      In this study Peg-Intron will be tested to see if it will give better results than
      Colchicine. At this time, there is currently no recommended maintenance treatment for
      patients who have failed to respond to Interferon/Rebetron/Peg Intron and have advanced
      fibrosis. The purpose of this study is to compare two treatments to slow down the progression
      of liver disease and to prevent liver failure and liver cancer. The treatment will not cure
      Hepatitis C, but is being evaluated to see if it can slow down disease progression.
    

Eligibility criteria:

        Inclusion Criteria:

          -  *Adult male or female, age 18 to 75 years

               -  HCV RNA positive by PCR

               -  Previous treatment with at least three months of interferon or interferon /
                  Ribavirin. Patients should have had no interferon for at least 2 months prior to
                  enrollment.

                    1. Non-responders are identified by failure to clear virus by PCR after a
                       minimum 3-month course of treatment and who have been off treatment for at
                       least 2 months with a positive PCR for HCV prior to entry into the current
                       study, 2) Partial responders have a reduction of 1 long in HCV RNA, but the
                       virus is still detectable, 3) Breakthrough patients have been negative on
                       treatment, but virus appeared while still on treatment, 4) Relapsers are
                       defined as negative PCR at some point during treatment, but virus reoccurred
                       or was detectable by HCV PCR when treatment stopped.

        Patients should have had a liver biopsy showing at least Stage 3 disease prior to being
        considered for this study. A baseline liver biopsy is necessary for inclusion in the study.
        Baseline liver biopsies can be performed within six months of entering the study.

        In patients with cirrhosis and endoscopic evidence of portal hypertension, a biopsy within
        the last 2 years is acceptable as the baseline biopsy. For patients with established
        cirrhosis on liver biopsy and no portal hypertension, a biopsy within 12 months can be used
        as the baseline biopsy if it is available for evaluation by the Pathology core. All these
        patients will still require liver biopsy at 2 years and 4 years. The decision to biopsy at
        2 and 4 years is also a clinical decision and in the presence of clinical progression or
        coagulopathy, or where there may be a risk from liver biopsy, the Investigator should call
        the PI, Dr. Afdhal for a waiver of biopsy. Patients with Ishak Stage 3 and 4 require a
        biopsy within 6 months of randomization.

          -  Hemoglobin >= 11 g/dl in males and 10 g/dl in females

          -  Neutrophil count > 1,500/mm3

        Platelet count: For standard dose of PEG-Intron 0.5mcg/kg platelet count must be greater
        than 70,000. Patients with platelet count 50 - 70,000 can start at 0.25mcg/kg for weeks 0 -
        4. If platelets fall to less than 30,000, stop treatment. If platelets remain > 50,000 at
        week 4, PEG-Intron can be increased to 0.5mcg/kg. Patients randomized to Colchicine with
        platelets 50,000 - 70,000 can be started at standard dose 0.6mg bid po with standard dose
        reduction.
