Comparison of Pharmacokinetic, Pharmacodynamic and Tolerability Profiles of CKD-11101, Darbepoetin Alfa (NESP^®) Biosimilar, to Those of NESP^® After a Single Subcutaneous or Intravenous Administration to Healthy Subjects.

ABSTRACT:

Introduction

Darbepoetin alfa (NESP^® and ARANESP^®) has a sustained erythropoietic activity with a longer half-life than conventional recombinant human erythropoietin. CKD-11101 is under clinical development as a biosimilar of darbepoetin alfa. The purpose of this study was to compare the pharmacokinetic (PK), pharmacodynamic (PD), and tolerability profiles of CKD-11101 with those of reference drug in healthy subjects.

Methods

This study was performed in two parts for healthy subjects. In each period, CKD-11101 and reference, both at 60 μg, were administered via intravenous (IV) or subcutaneous (SC) route of administration.

Results

After both IV or SC dose, the geometric mean ratio (GMR) of CKD-11101 to reference drug and its 90% confidence intervals (CIs) for C_max, AUC_0-last and AUC_0-∞ were all within 0.8-1.25. No statistically significant differences were noted in the maximum baseline adjusted reticulocyte count or the area under the baseline adjusted reticulocyte count-time between the CKD-11101 and reference drug after IV or SC dose (all p-value>0.05). Both CKD-11101 and reference drug were generally well tolerated.

Discussion

After a single IV or SC dose, the CKD-11101 was well tolerated and showed comparable PK and PD characteristics with reference drug.
