Real-life Surveillance Study of Patients With Chronic Hepatitis C Treated With PegIntron Injector and Rebetol (Study P04538)(COMPLETED)

Merck Sharp & Dohme LLC2,302 enrolled

Overview

The objective of the study is to assess the safety and efficacy of PegIntron injector and Rebetol administered to participants with chronic hepatitis C. Participants will be treated by general practitioners in clinical practice as part of the post-marketing surveillance study. The study will assess the rates of eradication of the hepatits C virus and the rates of serious adverse events reported with PegIntron (1.5 μg/kg/week) and Rebetol (800-1200 mg/day) in common medical practice in Germany.

Outcomes

Primary Outcomes

Number of Hepatitis C Virus Ribonucleic Acid (HCV-RNA) Negative Participants at End of Therapy (EoT)

HCV-RNA level was measured by polymerase chain reaction (PCR).

Time frame: 24 weeks in genotypes 2 and 3, and 48 weeks in genotypes 1, 4, 5, and 6

Number of Participants With Early Virologic Response (EVR)

EVR was defined as at least a 2 log reduction in HCV-RNA or HCV-RNA negativity from baseline to Week 12

Time frame: Treatment Week 12

Number of Participants With Sustained Virologic Response (SVR)

SVR was defined as HCV-RNA negativity at EoT and at the follow-up 6 months after the EoT

Time frame: 24 weeks post-treatment (Week 48 or 72, depending on genotype)

Number of HCV-RNA Negative Participants at Follow-up

HCV-RNA was measured by PCR.

Time frame: 24 weeks post-treatment (Weeks 48 or 72, depending on genotype)
