Brief Summary
Patients for whom treatment with peginterferon plus ribavirin was unsuccessful represent a category of patients for whom there is currently no worthwhile therapeutic alternative. Several studies have shown that there is a relation between plasma ribavirin concentrations and treatment response. Adequate ribavirin plasma concentrations, especially during the first 12 weeks of treatment, should be associated with a better chance of response to the treatment. The strategy for this study will be to use a loading dose of ribavirin before beginning the treatment with peg-interferon, thereby allowing for optimal ribavirin concentrations to be reached, and possibly improving the effectiveness of the treatment.

Peg-interferon alpha-2a, Ribavirin
EXPERIMENTALAdult patients with chronic hepatitis C and failure of prior treatment with peginterferon plus ribavirin(non-response or relapse). This is a pilot study with no control group.
Interventions
* 4 weeks RBV priming; * 24 or 48 weeks of Pegasys+Ribavirin (RBV) Treatment (depending on genotype); * 24 weeks Follow-Up Patients will receive PEGASYS® 180 µg in 0.5 mL (prefilled syringes) administered sc once weekly. Specific guidelines for adjusting the dose of PEGASYS® are provided in the product monograph.All PEGASYS® administrations will be via the sc route using sterile technique. Ribavirin 200 mg tablets
Eligibility Criteria
You may qualify if:
- Age \> 18 years
- Chronic hepatitis C and failure of prior treatment with peginterferon plus ribavirin (non-response: HCV-RNA decreased less than 2 logs after 3 months of treatment; relapse: HCV-RNA that becomes positive again after treatment is stopped
- Compensated hepatic disease (Child-Pugh ≤ 6)
- Provision by patient of his or her written consent
You may not qualify if:
- Females who are pregnant or lactating will be excluded
- Renal failure (estimated glomerular filtration rate \< 50 ml/min)
- A contraindication to treatment with peginterferon plus ribavirin (uncontrolled psychiatric illness, pregnancy/nursing/non-use of effective contraceptive method, uncontrolled epilepsy for at least 6 months, heart failure, unstable angina, hemoglobin \< 120 g/L, neutrophils \< 1,000/mm3, platelets \< 50 x 109/L, or any other condition that, in the investigator's opinion, contraindicates use of the treatment)
