Study Summary

This study will evaluate the efficacy and safety of peginterferon alfa-2a 40KD + ribavirin combination therapy given for 24 weeks versus 48 weeks in patients with chronic hepatitis C, genotype 2/3.

Primary Outcome

Sustained virological response (SVR) is defined as a single last HCV RNA measurement \<15 IU/ml (measured using the Roche COBAS AmpliPrep / COBAS TaqMan HCV Test) 24 weeks after scheduled treatment completion, defined as Week 44 or later for participants randomized to the 24-week treatment period or Week 68 or later for participants randomized to the 48-week treatment period. Participants without measurements at the end of the 24-week untreated follow-up period were considered non-responders in
