Comprehensive physicochemical characterization and biological assays are essential parts in assessing quality attributes of biologicals. Here, we compared the quality of different marketed recombinant human erythropoietin (epoetin) products: originators, Eprex and NeoRecormon as well as 2 biosimilars, Retacrit and Binocrit. In addition, assessment of batch-to-batch variability was included by collecting 2 or more batches of each product. Common assays which included sodium dodecyl sulfate-polyacrylamide gel electrophoresis, high-performance size-exclusion chromatography, asymmetrical flow field-flow fractionation, capillary zone electrophoresis, and potency testing were used...

The zebrafish (Danio rerio) is a very popular vertebrate model system, especially embryos represent a valuable tool for in vivo pharmacological assays. This is mainly due to the zebrafish advantages when compared to other animal models. Erythropoietin is a glycoprotein hormone that acts principally on erythroid progenitors, stimulating their survival, proliferation and differentiation. Recombinant human erythropoietin (rhEPO) has been widely used in medicine to treat anemia and it is one of the best-selling biotherapeutics worldwide...

The myelodysplastic syndromes (MDS) are a group of clonal hematopoietic disorders characterized by bone marrow failure and a risk of progression to acute myeloid leukemia (AML). Anemia affects the course of disease, quality of life (QOL), and cognitive function of MDS patients. Erythroid-stimulating agents (ESAs) are effective; however, not all patients respond to ESAs. To evaluate the effectiveness of a biosimilar epoetin α (Binocrit) for the treatment of anemia in low-/intermediate-1 risk MDS patients and to evaluate the impact of ESAs on QOL and on cognitive function, 24 consecutive patients aged over 65 years were treated with Binocrit at 40,000 IU once a week for 12 weeks and were followed for at least 3 months...

All prescribers will be familiar with the issues associated with the use of branded and generic 'chemical' medicines.(1) For biological products (e.g. epoetin, filgrastim), a biosmilar medicine is a new biological product that is similar to a medicine that has already been authorised to be marketed in the EU (the biological reference medicine).(2) Six biosimilar medicinal products are currently marketed in the UK-three versions of filgrastim (▾Nivestim, ▾Tevagrastim and Zarzio),(3-5) two versions of epoetin (Binocrit and Retacrit)(6,7) and one version of somatropin (Omnitrope)...

INTRODUCTION: A "biosimilar" or "similar biological medicinal product" is a biological agent that is similar in terms of quality, safety, and efficacy to an authorized reference biological medicine. Since the expiration of the epoetin alfa patent in Europe, three agents have received marketing authorization from the European Medicines Agency: Binocrit (epoetin alfa; aka Abseamed and Epoetin Alfa Hexal), Retacrit (epoetin zeta; aka Silapo), and Eporatio (epoetin theta; aka Biopoin and Ratioepo)...

OBJECTIVES: To evaluate the comparative cost efficiency across the European Union G5 countries of the erythropoiesis-stimulating agents (ESAs) epoetin α (originator [Eprex®] and biosimilar [Binocrit®]; once weekly), epoetin β (NeoRecormon®; once weekly), and darbepoetin α (Aranesp®; once weekly or once every 3 weeks) under different scenarios of fixed and weight-based dosing in the management of chemotherapy-induced anemia. METHODS: Direct costs of ESA treatment were calculated for one patient with cancer undergoing chemotherapy (six cycles at 3-week intervals) with ESA initiated at week 4 and continued for 15 weeks...

AIM: To evaluate the effectiveness of a biosimilar erythropoiesis-stimulating agent (Binocrit) for the treatment of patients with cancer and chemotherapy-induced anemia in real-life clinical practice. MATERIALS & METHODS: Data were collected retrospectively from patients at five European centers (in France, Italy, The Netherlands, Romania and Spain) who received treatment with Binocrit. Hemoglobin (Hb) levels were recorded at regular intervals during Binocrit therapy for up to 26 weeks...

The aim of this study was to develop an integrated pharmacokinetic and pharmacodynamic (PK/PD) model and assess the comparability between epoetin alfa HEXAL/Binocrit (HX575) and a comparator epoetin alfa by a model-based approach. PK/PD data-including serum drug concentrations, reticulocyte counts, red blood cells, and hemoglobin levels-were obtained from 2 clinical studies. In sum, 149 healthy men received multiple intravenous or subcutaneous doses of HX575 (100 IU/kg) and the comparator 3 times a week for 4 weeks...

REVIEW
Alexander Berghout
Similar biotherapeutic products (SBPs) or biosimilars are biologics developed by pharmaceutical manufacturers to match originator biologics that have been on the market for a long time and lost their exclusivity (patent and market protection). The recently issued WHO guidelines on evaluation of SBPs provide clear guidance for manufacturers and regulators on how to develop and gain approval for these products. The present contribution illustrates the rationale for and general principles of the clinical programs used in the development of SBPs, taking the example of the three biosimilar products developed and marketed in Europe by Sandoz, namely growth hormone (Omnitrope®, the first ever EU biosimilar approval), erythropoietin α (Binocrit®), and filgrastim (Zarzio®)...

BACKGROUND: HX575, licensed under the brand names Binocrit®, Epoetin Alfa Hexal®, and Abseamed®, was approved in 2007 as the first biosimilar recombinant human erythropoietin alfa (epoetin alfa) in the EU using Erypo®/Eprex® as reference product. OBJECTIVES: The aim of this study was to investigate the bioequivalence and potency of registered epoetin alfa products that have not been compared before in a randomized controlled clinical study. METHODS: The study was conducted in two parts: part A compared the European-marketed HX575 and the US-marketed Epogen®; part B compared the European-marketed Erypo®/Eprex® and HX575 manufactured at two different drug substance production sites (HX575-TT denoting the already-approved technology-transfer product from an additional manufacturing site)...

PURPOSE: To compare the quality of therapeutic erythropoietin (EPO) products, including two biosimilars, with respect to content, aggregation, isoform profile and potency. METHODS: Two original products, Eprex (epoetin alpha) and Dynepo (epoetin delta), and two biosimilar products, Binocrit (epoetin alpha) and Retacrit (epoetin zeta), were compared using (1) high performance size exclusion chromatography, (2) ELISA, (3) SDS-PAGE, (4) capillary zone electrophoresis and (5) in-vivo potency...

OBJECTIVE: To compare the steady-state pharmacokinetics and pharmacodynamics following multiple subcutaneous administration of a new erythropoiesis stimulating agent (HX575, Binocrit, Sandoz GmbH, Holzkirchen, Germany) with that of epoetin beta (NeoRecormon, Roche Ltd., Welwyn Garden City, UK). METHODS: An open, randomized, parallel group study was conducted in 80 healthy adult males.
