Participants with CrCl 30 to 50 mL/min will receive 12 weeks of peginterferon alfa-2a, 180 micrograms (mcg) via subcutaneous (SC) injection once weekly, in combination with ribavirin, 600 milligrams (mg) orally (PO) daily in two divided doses. Those with Genotype 2 or 3 disease may receive an additional 12 weeks of the same regimen, and those with another genotype may receive an additional 36 weeks.
Participants with CrCl <30 mL/min will receive 12 weeks of peginterferon alfa-2a, 180 mcg via SC injection once weekly, in combination with ribavirin, 400 mg PO daily in two divided doses. Those with Genotype 2 or 3 disease may receive an additional 12 weeks of the same regimen, and those with another genotype may receive an additional 36 weeks.
Participants requiring hemodialysis will receive 12 weeks of peginterferon alfa-2a, 135 mcg via SC injection once weekly, in combination with ribavirin, 200 mg PO every morning. Those with Genotype 2 or 3 disease may receive an additional 12 weeks of the same regimen, and those with another genotype may receive an additional 36 weeks.
Participants with CrCl >80 mL/min will receive 12 weeks of peginterferon alfa-2a, 180 mcg via SC injection once weekly, in combination with ribavirin, 800 to 1200 mg PO daily in two divided doses. Those with Genotype 2 or 3 disease may receive an additional 12 weeks of the same regimen, and those with another genotype may receive an additional 36 weeks.
