Relapse Rate in Hepatitis C Patients Treated With Peginterferon Alfa-2b Plus Ribavirin in Common Clinical Practice in France (P05484)(Completed) (RE-CHUT)
The objective of this study is to determine the relapse rate in the French patient population with chronic hepatitis C (CHC) previously treated with PegInterferon Alfa-2b (Peg-IFN alfa-2b) plus Ribavirin according to standard clinical practice. Treatment was to be completed prior to the enrollment in the current study. The study will also aim to identify factors that are predictive of relapse. Relapse rate is defined as the percentage of patients with negative viral load at end of treatment who again have positive viral load at 6 months after the end of treatment.

- Number of Participants With Positive Hepatitis C Virus (HCV)-Ribonucleic Acid (RNA) at 24 Weeks Off-treatment [ Time Frame: 24 weeks post end of treatment (EOT) ] [ Designated as safety issue: No ]HCV-RNA virus levels were measured by polymerase chain reaction (PCR) assay 24 weeks post end of treatment (EOT) with Peg-IFN alfa-2b + ribavirin. Participants with positive HCV-RNA were considered relapsers.
- Number of Participants With Rapid Virologic Response (RVR), Early Virologic Response (EVR), or Slow Response Who Relapsed After Treatment [ Time Frame: 24 weeks post EOT ] [ Designated as safety issue: No ]Negative HCV-RNA at Week 4 of treatment with Peg-IFN alfa-2b + ribavirin was considered RVR; negative HCV-RNA at Week 12 of treatment with Peg-IFN alfa-2b + ribavirin was considered EVR; negative HCV-RNA between Week 12 and the end of treatment with Peg-IFN alfa-2b + ribavirin was considered a slow response. For participants who achieved RVR, EVR, or slow response, the relapse rate at 24 Weeks post EOT was to be determined on this observational study; relapse was defined as positive HCV-RNA.
- Assessment of Pre-treatment Risk Factors of Relapse in Participants With Sustained Virologic Response [ Time Frame: Baseline and 24 weeks post EOT ] [ Designated as safety issue: No ]Baseline risk factors included but were not limited to viral load, genotype 1a versus 1b, histology, treatment compliance, gender, age, and substance abuse. Sustained virologic response was defined as having negative HCV-RNA at 24 weeks post EOT. Relapse was defined as positive HCV-RNA.
- Number of Participants With Positive HCV-RNA at 72 Weeks Off-treatment [ Time Frame: 72 weeks post EOT ] [ Designated as safety issue: No ]HCV-RNA virus levels were measured by polymerase chain reaction (PCR) assay 72 weeks post EOT with Peg-IFN alfa-2b + ribavirin. Participants with positive HCV-RNA at Week 72 post EOT were considered late relapsers.

Peg-IFN alfa-2b + ribavirin
Participants with chronic hepatitis C (CHC) treated with Peg-IFN alfa-2b + ribavirin as first treatment, in common clinical practice, who had negative hepatitis-C virus (HCV)-ribonucleic acid (RNA) by the end of treatment (24 or 48 weeks per product labeling).
Biological: Peg-IFN alfa-2b
Peg-IFN alfa-2b administered in accordance with approved labeling
Other Name: SCH 054031Drug: Ribavirin
Ribavirin administered in accordance with approved labeling
Other Name: SCH 018908
Non-probability sampling: The study population consists of adult patients over the age of 18 affected by CHC who were previously treated for the first time with Peg-IFN alfa-2b plus ribavirin and achieved end-of-treatment response. Five hundred ninety patients must be recruited in order to evaluate the objectives of the study. The patients must meet all inclusion criteria and not meet any of the exclusion criteria in order to be included in the study.
