- Conditions
- Hepatitis C, Chronic
- Interventions
- Registration Number
- NCT02864199
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This study will evaluate the pharmacokinetics (area under the curve \[AUC\], maximum concentration \[Cmax\], and other parameters) and tolerability of peginterferon alfa-2a and ribavirin combination therapy following single and multiple doses in participants with CHC infection and moderate to severe renal impairment or end-stage renal disease (ESRD) receiving hemodialysis. The anticipated time on study treatment is up to 48 weeks, and the target sample size is 48 individuals.

Group Intervention Description Group C: Hemodialysis/ESRD Ribavirin 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. Group D: Normal Renal Function Peginterferon alfa-2a 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. Group A: Moderate Renal Impairment Peginterferon alfa-2a 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. Group B: Severe Renal Impairment Ribavirin 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. Group A: Moderate Renal Impairment Ribavirin 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. Group B: Severe Renal Impairment Peginterferon alfa-2a 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.
