A Phase 4 interventional study of Copegus and Copegus in Hepatitis C, Chronic, sponsored by Hoffmann-La Roche. Completed at 132 sites in 9 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2016-02-23.
Sponsored by Hoffmann-La Roche · Phase 4, Interventional, and Treatment
This study will evaluate the efficacy and safety of different durations of treatment with PEGASYS combined with ribavirin in patients with CHC genotype 2 or 3 infection who have never previously received interferon (IFN) therapy. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ individuals.
2,709 studies on the registry are indexed under Hepatitis A; 142 are open to participants now.
This study's enrollment of 1,469 is above the median of 100 across 1,886 interventional studies indexed under Hepatitis A.

Percentage of Participants With Sustained Virological Response (SVR)
SVR was defined as the percentage of participants with undetectable HCV RNA at 24 weeks after the completion of the study treatment. The negative assessment was required to be the last one collected at or after week 36 (ie, on or after study Day 253) for the 16-week treatment group or at or after week 44 (ie, on or after study Day 309) for the 24-week treatment group.

Percentage of Participants With Virological Response at The End of Study Treatment
Virological response was defined as the percentage of participants with undetectable HCV RNA at the completion of the study treatment. The negative assessment was required to be the last one collected in the Week 16 time window for the 16-week treatment group or in the Week 24 time window for the 24-week treatment group.

Percentage of Participants Virological Response 12 Weeks Post-Treatment
Virological response 12 weeks post-treatment was defined as the percentage of participants with undetectable HCV RNA 12 weeks after the completion of the study treatment . The negative assessment was required to be the last one collected in the week 28 time window for the 16- week treatment group or in the week 36 time window for the 24-week treatment group.
