This study is being done to find out if the addition of boceprevir to standard of care (SOC) treatment with peginterferon alfa-2b (PegIFN-2b) + ribavirin (RBV) is effective for participants with chronic hepatitis C (CHC) genotype 1 and cirrhosis who were not successfully treated by previous SOC. All participants will receive treatment with SOC alone for 4 weeks and then boceprevir will be added to the treatment regimen for 44 additional weeks of combined treatment.
