Pharmacokinetics, pharmacodynamics, and safety of peginterferon beta-1a in subjects with normal or impaired renal function.

ABSTRACT: Peginterferon beta-1a was efficacious in a Phase 3 relapsing multiple sclerosis trial, and its safety profile was consistent with other beta interferons. This study evaluated the impact of renal impairment on the pharmacokinetics and pharmacodynamics (neopterin elevation; a biomarker of pharmacological activity induced by interferon beta-1a) of peginterferon beta-1a following a single subcutaneous dose at 63 μg (n = 5) or 125 μg (n = 30). The results showed a fractional increase in area-under-the-concentration-time curve (AUC [30-53%]) and peak serum concentration (Cmax [26-42%]) in subjects with mild, moderate, and severe renal impairment, versus healthy subjects; AUC and Cmax were similar for healthy subjects and end-stage-renal-disease patients receiving hemodialysis.
