Study of Long-term Peg Intron vs. Colchicine in Non-responders.

Completed · Phase 4

Conditions studied: Hepatitis C Virus, Advanced Fibrosis, Cirrhosis

In brief

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.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• *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.
• 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
• Total bilirubin < 3gm/dL
• Fasting blood sugar <= 115 mg/dl or within 20% of the upper limit of normal for non-diabetic patients
• Albumin (> 2.8mg/dl)
• Serum creatinine < 1.4 mg/dL
• TSH within the normal range (Patients with thyroid disease who are well controlled are eligible if the remainder of the inclusion/exclusion criteria are met)
• HIV negative.
• HBsAg negative
• Childs Pugh score of less than or equal to 7
• Serum positive for anti-hepatitis C antibodies or HCV RNA.
• Alpha-fetoprotein < 100ng/ml with ultrasound negative for focal mass or HCC. For 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
• Ultrasound with no evidence of focal mass suggestive of hepatoma (within 6 months of informed consent).
• Documentation that sexually active female patients of childbearing potential are 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.
• Written informed consent specific for this protocol has been obtained prior to entry.

You may not qualify if…

• Any cause of liver disease based on patient history and biopsy (where applicable) other than chronic hepatitis C including but not limited to:
• Co-infection with hepatitis B or HIV
• Hemochromatosis (confirmed by genetic testing)
• Alpha-1 antitrypsin deficiency
• Wilson's disease
• Renal or liver transplant patients
• Autoimmune hepatitis
• Alcoholic liver disease
• Obesity induced liver disease
• Drug related liver disease
• In addition:
• Evidence of decompensated liver disease such as a history or presence of ascites, and spontaneous encephalopathy. Patients with past bleeding esophageal varices that have not bled for more than 1 year can be included.
• Hypersensitivity to alpha interferon
• Drug related liver disease
• Hemoglobinopathies (e.g. Thalassaemia, sickle cell disease).
• Patients with clinically significant retinal abnormalities.
• Substance abuse, such as alcohol (·> 80 gm/day), I.V. drugs and inhaled drugs. If the patient has a history of substance abuse, to be considered for inclusion into the protocol, the patient must have abstained from using the abused substance for at least 6 months. Patients on methadone will be allowed in the study with no restrictions as is now standard of care in HCV therapy.
• Patients with a history of organ transplantation will be excluded.
• Preexisting psychiatric conditions, especially depression, or a history of severe psychiatric disorder, such as major psychoses, suicidal ideation and/or suicidal attempt are excluded. Patients with a history of mild depression may enter the protocol if they meet the following eligibility criterion and are monitored more intensively.
• Mild depression: to include either situational depression of a limited period or depressive symptoms, which do not significantly interfere with the patient's work or daily functions.
• Any patient with an active manic element to his/her previous symptom complex will be excluded.
• Any known pre-existing medical condition that could interfere with the patient's participation in and completion of the study such as:
• Pre-existing psychiatric condition, especially severe depression, or a history of severe psychiatric disorder
• CNS trauma or seizure disorder requiring therapy
• Significant cardiac dysfunction in the previous 6 months e.g. angina, CCF, hypertension or arrhythmia Patients on treatment are eligible as long as they have been symptom free for the previous 6 months.
