| Abstract | BACKGROUND AND OBJECTIVES: A new biosimilar human recombinant epoetin alfa product (PDA10) has been developed by PanGen Biotech Inc., Korea. This study was planned to demonstrate the pharmacokinetic and pharmacodynamic comparability of PDA10 to an existing epoetin alfa (Eprex) after a single intravenous administration to healthy adult male volunteers. METHODS: A randomized, double-blinded, single-dose, crossover study was conducted in 30 subjects. The subjects were assigned randomly to one of two sequence groups, and single doses of 100 IU/kg PDA10 or Eprex were administered intravenously on each of 2 treatment days separated by a 4-week washout period. Plasma erythropoietin concentrations were measured using an enzyme-linked immunosorbent assay and the pharmacokinetic parameters of the two treatments were compared. The time course and area under the effect curve (AUEC) of absolute reticulocyte counts were used as surrogate parameters for the pharmacodynamic evaluation. Adverse events (AEs) were recorded. RESULTS: A total of 30 subjects were enrolled, and 27 completed the study. The geometric mean ratios (PDA10/Eprex) of erythropoietin for maximum plasma concentration (C max) and area under the plasma concentration-time curve to the last measurable concentration (AUC0-last) after intravenous administration of 100 IU/kg were 1.00 (90% confidence interval [CI] 0.96-1.05) and 0.96 (90% CI 0.93-1.00). The absolute reticulocyte counts of PDA10 and Eprex were similar, as determined from the maximum reticulocyte count and AUEC0-last values. Treatment-emergent AEs were mild and occurred in seven subjects. CONCLUSION: PDA10 and Eprex met the regulatory criteria for bioequivalence with respect to their pharmacokinetic profiles and pharmacodynamic actions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
