Effectiveness of Pegylated Interferon Plus Ribavirin in the Treatment of Active and Past Intravenous Drug Users Infected With Hepatitis C


We plan to examine how successful treatment with the current standard treatment of pegylated
interferon and ribavirin is in those who continue to use injection drugs. Our goal is to
determine whether reasonable success rates can be achieved in active drug users that would
then further justify their routine treatment.


Inclusion Criteria:



1. Men or women age 18 to 75 years.

2. Chronic hepatitis C infection based on a history of positive anti-HCV antibody and/or
HCV RNA at least 6 months prior to study entry.

3. Positive HCV-RNA by Roche Amplicor HCV test at screening

4. Serum ALT > 1.5 times upper limit of normal

5. Active or past use of injection drugs or crack cocaine by self-report. Active use is
defined as injection drug use at least 1/month and within 3 months of the date of
randomization. Past use is defined as no injection drug use or crack cocaine use
within the past 5 years.

6. Compensated liver disease

7. Negative urine or blood pregnancy tests (for women of childbearing potential)
documented within 24-hours prior to first dose of study drug.

8. All fertile males and females must use effective contraception during treatment and
during the 6 months after treatment end if sexually active (This will be provided
free of charge to active IDUs).

Exclusion Criteria:

1. Presence of clinically evident ascites requiring active diuretic therapy, history of
or therapy for hepatic encephalopathy, or history of variceal bleeding within the
last two years.

2. Platelet count < 60,000/mm3

3. Serum ALT level > 10 times upper limit of normal

4. Serum creatinine level > 1.5 times the upper limit of normal (Deleted February 27,
2007, Protocol Amendment #4, Ethics approval March 28, 2007)

5. Hematology outside of specified limits: neutrophil count < 1000/mm3, hemoglobin < 10
g/L in males and < 9 g/L in females

7. Unstable or uncontrolled thyroid disease 8. Treatment with interferon- and/or ribavirin
within the previous 12 months 9. Presence of clinically significant cryoglobulinemia
vasculitis (e.g. skin rash, arthritis, or renal insufficiency due to cryoglobulinemia) 10.
Presence or history of autoimmune hepatitis, alpha-1-anti-trypsin deficiency, genetic
hemochromatosis, Wilson disease, drug- or toxin-induced liver disease, alcohol-related
liver disease, primary biliary cirrhosis, or sclerosing cholangitis.

11. Chronic hepatitis B infection or positive HbsAg at screening 12. Known history of HIV
infection or positive HIV antibody test by Western Blot.

13. A disease known to cause significant alteration in immunologic function, including
hematological malignancy or autoimmune disorder.

14. Concurrent therapy with immunosuppressive drugs or cytotoxic agents, such as
prednisone, cyclosporine, azathioprine or chemotherapeutic agents.

15. History of unstable or deteriorating cardiac, pulmonary or renal disease. 16.
Preexisting (within last two years) or active psychiatric condition including severe
untreated depression, major psychoses, suicidal ideation or suicidal attempts.

17. Severe or poorly controlled diabetes mellitus 18. Any serious or chronic disease that
may affect the assessment of safety or efficacy parameters.

19. Patients who have had a liver transplant 20. Patients infected with HCV genotypes 4, 5
or 6 (< 1% of infected current/past IDUs)
