Condition(s) targeted: Hepatitis C Virus; Advanced Fibrosis; Cirrhosis

Intervention: PEG interferon Alfa-2b; Colchicine (Drug)

Phase: Phase 4

Status: Active, not recruiting

Official(s) and/or principal investigator(s):

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.

Clinical Details

Official title: Phase IV Study of Long Term Peg-Intron for Patients Who Have Failed to Respond to Rebetron/Interferon With Advanced Fibrosis and Cirrhosis Secondary to Hepatitis C- The Copilot Trial

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome:

Determination of the effect of PEG-Intron 0.5mg per kg weekly sc versus colchicine 0.6mg bid daily on:

4 year survival or hepatic transplantation

Variceal or portal hypertensive bleeding

Development of jaundice, ascites or encephalopathy with an increase in CPT of > 2 points

Development of hepatoma

Secondary outcome:

Evaluation of safety and tolerability of long term maintenance PEG-Intron in patients with cirrhosis

Evaluation of the effect of long term maintenance PEG-Intron on quality of life

Evaluation of surrogate markers of fibrosis in determining effect of long term maintenance PEG-Intron on prevention of progression of fibrosis and correlation of fibrosis markers with pathology.

Development of portal hypertension

Progression of histological fibrosis

Detailed description: We are proposing a randomized trial of Peg-Intron 0. 5mcg per kg weekly versus colchicine 0. 6mg bid in prior non-responders to Interferon, Rebetron, PegIntron, or PegIntron & Ribavirin or any third agent such as Pegasys, CellCept, Amantadine with advanced fibrosis/cirrhosis. The specific aims of this proposal are to evaluate the role of long term Peg-Intron therapy on the natural history of patients with advanced chronic HCV infection with a primary focus on prevention of hepatic decompensation, progression of fibrosis and hepatoma development. The study design will focus on 3 monthly clinical evaluation for decompensation of liver function, rigorous clinical screening for development of hepatocellular cancer and liver biopsies for determination of progression of liver fibrosis every second year.

Eligibility

Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.

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

- Platelets > 50, 000/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.

- Prothrombin time <= 3secs prolonged compared to control or an equivalent INR < 1. 5

- Fasting blood sugar <= 115 mg/dl or within 20% of the upper limit of normal for

non-diabetic patients

- Albumin (> 2. 8mg/dl)

- HBsAg negative

- Childs Pugh score of less than or equal to 7

- Serum positive for anti-hepatitis C antibodies or HCV RNA.

any patient with an Alpha-fetoprotein >100 ng/ml either a triple phase contrast CT scan or MRI with gadolinium must show no focal mass or evidence of HCC

practicing adequate contraception during the treatment period. A urine pregnancy test obtained at entry prior to the initiation of treatment must be negative. Female patients must not be breast-feeding. Documentation that sexually active male patients are practicing acceptable methods of contraception during the treatment period.
