Phase 4
Completed
Conditions

Interventions
Drug: Peginterferon alfa-2a plus ribavirin for HCV genotype 1
Drug: Peginterferon alfa-2a plus ribavirin for HCV genotype 2/3
Registration Number
NCT01596517

Brief Summary

The purpose of this study is to investigate the efficacy and effectiveness of peginterferon alfa-2a and ribavirin therapy in Korean chronic hepatitis C patients.

Detailed Description

A retrospective analysis of a prospective, multicenter, industry-sponsored, open-label, uncontrolled, community-based clinical trial of combination of peginterferon alfa-2a and ribavirin (Pegasys Expanded Access Program) conducted at 6 tertiary referral centers in Korea between 2003 and 2004 and a cohort of hepatitis C patients who were treated in a single tertiary referral hospital (Asan Medical Center, Seoul, Korea) between 2004 and 2008

One is CHC patients who are treated with combination of peginterferon alfa-2a and ribavirin in a prospective, multicenter, industry-sponsored, open-label, uncontrolled, community-based clinical trial (Pegasys Expanded Access Program) conducted at 6 tertiary referral centers in Korea between 2003 and 2004.

Primary Outcome Measures
NameTimeMethod
The proportion of patients achieving sustained virological response (SVR)at 24 weeks after cessation of treatment

SVR is defined as a documented undetectable serum HCV RNA by PCR at 24 weeks after cessation of treatment

Secondary Outcome Measures
NameTimeMethod
The proportion of patients achieving early virological response (EVR)at 12 weeks of treatment

EVR is defined as reduction of HCV RNA level by 2 log or more at 12 weeks of treatment

the proportion of patients achieving complete EVR (cEVR)at 12 weeks of treatment

cEVR is defined as HCV RNA undetectable by PCR at 12 weeks of treatment

The proportion of patients achieving end-of-treatment response (ETR)at week 48 for HCV genotype 1 and at week 24 for HCV genotype 2/3

ETR is defined as HCV RNA undetectable at the end of treatment.
