This is a controlled, randomized, parallel-groups, open-label, multinational study designed to evaluate the efficacy and safety of PEG-Intron® (pegylated interferon alfa-2b) plus Rebetol® (ribavirin) in subjects with chronic hepatitis C. It is designed to evaluate whether 72 weeks of treatment with PEG-Intron plus Rebetol is more effective than 48 weeks of treatment in subjects with Genotype 1 chronic hepatitis C who exhibit a slow response to treatment.

Primary Outcome Measures:
- Sustained Virologic Response, Defined as a Plasma HCV-RNA (Hepatitis C Ribonucleic Acid) Level Below the LLQ (Lower Level of Quantitation) at 24 Weeks Post-treatment. [ Time Frame: 48 or 72 weeks of treatment plus 24 weeks of follow-up. ]LLQ = 30 IU/mL by reverse transcription polymerase chain reaction (RT-PCR) (Taqman Roche)
|Study Start Date:||December 2004|
|Study Completion Date:||May 2008|
|Primary Completion Date:||May 2008 (Final data collection date for primary outcome measure)|
Active Comparator: Standard therapy
Slow responders (defined as being polymerase chain reaction [PCR] positive at Week 12 with at least 2 log reduction in viral load and PCR negative at Week 24) who are randomized at Week 48 to stop treatment at Week 48.
Drug: Combination of pegylated interferon alfa-2b (PEG-Intron®) and ribavirin (Rebetol®)
Experimental: Extended therapy
Slow responders (defined as being PCR positive at Week 12 with at least 2 log reduction in viral load and PCR negative at Week 24) who are randomized at Week 48 to continue treatment to Week 72.
Drug: Combination of pegylated interferon alfa-2b and ribavirin
