Study Arms:
- Group A - 8 weeks therapy (Type: EXPERIMENTAL): 8 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 2 weeks of therapy.
- Group B - 16 weeks therapy (Type: EXPERIMENTAL): 16 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 4 weeks of therapy.
- Group C - 24 weeks therapy (Type: EXPERIMENTAL): 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 6 weeks of therapy.
- Group D - 32 weeks (gt1) or 24 weeks (gt 2/3) (Type: EXPERIMENTAL): 32 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 8 weeks of therapy (genotype 1) or 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 8 weeks of therapy.
- Group E - 48 weeks (gt 1) or 24 weeks (gt 2/3) (Type: EXPERIMENTAL): 48 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 12 weeks of therapy (genotype 1) or 24 weeks total of Pegylated interferon and ribavirin if undetectable HCV RNA after 12 weeks of therapy (genotype 2/3).
- Untreated Group (Type: NO_INTERVENTION): Observation only. No treatment for hepatitis C administered. Subjects who have undetectable HCV RNA at baseline, do not wish to commence treatment or are ineligible for treatment.
