A Study of Peginterferon Alfa-2a (Pegasys) and Ribavirin (Copegus) Combination Therapy in Participants With Chronic Hepatitis C (CHC) and Various Degrees of Renal Impairment

August 9, 2016 updated by: Hoffmann-La Roche

Non-Randomized, Multicenter Study to Evaluate the Pharmacokinetics and Safety of Peginterferon Alfa-2a and Copegus Combination Therapy After Single and Multiple Doses in Patients With Chronic Hepatitis C and Moderate Renal Impairment, Severe Renal Impairment, or End-Stage Renal Disease Undergoing Hemodialysis

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.
