UPLC-MS assessment on the structural similarity of recombinant human erythropoietin (rhEPO) analogues from manufacturers in China for attribute monitoring.
Abstract Recombinant human erythropoietin (rhEPO) is a glycoprotein that acts as the main hormone involved in regulating red blood cell production to treat anemia caused by chronic kidney disease or chemotherapy. Since the expiration of the patent of the innovator epoetin alfa, numerous rhEPO products have emerged in global markets. As described here, multiple complementary analytical approaches are utilized for the extensive characterization of rhEPO molecules, and more importantly for the structural comparison of the rhEPO analogues on the Chinese market. The focus of this study is placed on the overall ...

Oral Hypoxia-Inducible Factor Prolyl Hydroxylase Inhibitor Roxadustat (FG-4592) for Treatment of Anemia in Chronic Kidney Disease: A Placebo-Controlled Study of Pharmacokinetic and Pharmacodynamic Profiles in Hemodialysis Patients.
Abstract Roxadustat (FG-4592), an oral hypoxia-inducible factor prolyl hydroxylase inhibitor that stimulates erythropoiesis, was evaluated in a phase 1b study in patients with end-stage renal disease with anemia on hemodialysis. Seventeen patients, on epoetin-alfa maintenance therapy with stable hemoglobin levels ≥10 g/dL, had epoetin-alfa discontinued on day 3 and were enrolled in this double-blind placebo-controlled study. Two cohorts were randomized 3:1 (roxadustat: placebo). Patients received single doses of roxadustat (1 or 2 mg/kg) or placebo 1 hour after hemodialysis on day 1 and 2 hours before ...

Surgical prescription of epoetin alfa in contemporary total hip arthroplasty: a prospective comparative study
ConclusionsThe amended protocol does not lead to increased peri-operative bleeding. Advances in intra-operative methods to reduce the bleeding allow changing indications of EPO in patients undergoing THA with a low level of Hb. (Source: International Orthopaedics)

Glycan analysis of erythropoiesis-stimulating agents
In this study, a combination of chromatography and mass spectrometry analysis has been used to characterise and compare the glycosylation profiles of five ESA products; Eprex® (epoetin alfa), NeoRecormon® (epoetin beta), Binocrit® (epoetin alfa biosimilar), Silapo (epoetin alfa biosimilar) and Aranesp® (darbepoetin alfa). The methods utilised include mixed-mode anion-exchange/hydrophilic interaction chromatography (AEX/HILIC-MS) for N-glycan identification and quantitation, and HILIC-MS for O-glycan characterisation. The products exhibit notable differences in N- and O-glycosylation, including attributes such as sialic...

Biosimilar Erythropoiesis-Stimulating Agents in Chronic Kidney Disease
Publication date: July 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 4Author(s): Hitesh H. Shah, Steven FishbaneAnemia is a well-known complication of advanced CKD and treatment with erythropoietin analogues (epoetin) remains a key component of management. Although biologic agents, including epoetin, play an extremely important role in the treatment of various medical conditions, their cost can be prohibitive. As a result, several biosimilar agents have now been approved by the U.S. Food and Drug Administration. Biosimilar epoetin has been used in Europe since 2007. In this article, we will review biosim...

Cardiovascular Safety and All-Cause Mortality of Methoxy Polyethylene Glycol-Epoetin Beta and Other Erythropoiesis-Stimulating Agents in Anemia of CKD: A Randomized Noninferiority Trial.
CONCLUSIONS: In patients with anemia of CKD, once-monthly methoxy polyethylene glycol-epoetin beta was noninferior to conventional, shorter-acting erythropoiesis-stimulating agents with respect to rates of major adverse cardiovascular events or all-cause mortality.

Analysis of Pharmacokinetic and Pharmacodynamic Parameters in EU- Versus US-Licensed Reference Biological Products: Are In Vivo Bridging Studies Justified for Biosimilar Development?
ConclusionOur analysis reveals that, in most cases, the reference biological products originated from the EU and those from the USA are almost indistinguishable in terms of PK/PD properties. Additional in vivo bridging studies between reference products from different global regions may not be required if similar physicochemical and structural properties are evident in vitro.

Definition and Validation of a Novel Metric of Erythropoiesis-Stimulating Agent Response in Hemodialysis Patients.
Abstract Erythropoiesis-stimulating agents (eg, epoetin alfa) are the primary treatment for anemia in patients with end-stage renal disease . Hemoglobin variability in and out of a narrow target range is common and associated with higher morbidity and mortality risk. More robust erythropoiesis-stimulating agent response metrics are needed to define optimal dosing and their association with clinical outcomes. In this cross-sectional, single-center, retrospective study, 49 patients with end-stage renal disease on hemodialysis were followed over 12 months. To quantify hemoglobin deviations outside the target ...
