  Purpose
Patients with HCV genotype 1 and IL28B CC Polymorphism who have a rapid virological response to treatment are randomised to either 24 or 48 weeks HCV treatment. Our hypothesis is that there is no important difference in effect between the two treatment effect.

Chronic Hepatitis C
Drug: Peginterferon alfa2a
Drug: Ribavirin
Phase 3

Primary Outcome Measures:
  • Sustained virological response (SVR) [ Time Frame: 24 weeks after the end of treatment ] [ Designated as safety issue: No ]
    Undetectable HCVRNA in serum(<15IU/ml) 24 weeks after the end of treatment


Secondary Outcome Measures:
  • Change in health related quality as measured by short from 36 (SF-36) from baseline to 24 weeks after the end of treatment [ Time Frame: baseline, 24 weeks after the end of treatment ] [ Designated as safety issue: No ]
  • Sick leave in patients treated for 24 or 48 weeks treatment [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 200
Study Start Date: May 2011
Estimated Study Completion Date: August 2014
Estimated Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 24-Week treatment group
Genotype 1 chronic hepatitis C patients with IL28B CC Polymorphism and rapid virological response(undetectable HCV RNA at weeks 4) in this group will be treated with Peginterferon alfa-2a plus ribavirin for an additional 20 weeks
Drug: Peginterferon alfa2a
patients receive a dose of 180 µg of PEGASYS once a week for 24 weeks
Drug: Ribavirin
patients receive a dose 800 to 1200 mg of ribavirin once a day(according to weight) for 24 weeks
Active Comparator: 48-Week treatment group
Genotype 1 chronic hepatitis C patients with IL28B CC Polymorphism and rapid virological response(undetectable HCV RNA at weeks 4) in this group will be treated with Peginterferon alfa-2a plus ribavirin for an additional 44 weeks
Drug: Peginterferon alfa2a
patients receive a dose of 180 µg of PEGASYS once a week for 48 weeks
Drug: Ribavirin
patients receive a dose 800 to 1200 mg of ribavirin once a day(according to weight) for 48 weeks
