Study Summary

This study will compare the efficacy and safety of treatment with pegylated-interferon alfa-2a plus ribavirin in participants with non-genotype 2/3 CHC who, after 12 weeks of study treatment, have undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or a greater than or equal to (\>=) 2 log10 drop in HCV-RNA. Participants will be randomized to receive pegylated-interferon alfa-2a 180 micrograms subcutaneously weekly plus ribavirin (1000-1400 milligram \[mg\]) orally daily for the specified duration, followed by 24 weeks of treatment-free follow-up. Participants with detectable HCV-RNA and less than (\<) 2 log10 drop in HCV-RNA at week 12 will discontinue therapy.

Primary Outcome

SVR was defined as success if the participant had HCV RNA levels \<15 IU/mL as measured by COBAS AmpliPrep/COBAS TaqMan® HCV test at the 24-week untreated follow-up visit (HCV-RNA levels obtained at least 18 weeks after last dose of either pegylated-Interferon alfa-2a or ribavirin were considered if the 24-week untreated follow-up visit data were missing). Percentage of participants with SVR for Groups A and B was reported in this analysis.
