Generic name: Methoxy polyethylene glycol-epoetin beta 30ug in 0.3mL 6); the mean (SD) Hb within 14days prior to transfusion in these periods was 8.8 (1.41) and 8.3 (1.26), respectively. Conversion from Another ESA: dosed once monthly or once every two weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion (2.2). Data on clinical and laboratory parameters relating to CKD management were abstracted from patient records and entered into an anonymized study-specific central database by study center staff. An additional analysis was performed to explore the effect of transfusions on the DCR, by exclusion of patients with a transfusion within 90days prior to or during either EP from the analysis.

DA, launched in 2001 [5, 7], contains 5 N-linked oligosaccharide chains, rather than the 3 contained in short-acting epoetins, which confer an approximately threefold longer serum half-life and mean residence time, allowing extended inter-dosing intervals [6]. Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events [see Boxed Warning and Clinical Studies (14)]. 2002;162:14011408. Action Stimulates erythropoesis (production of red blood cells). Matsumura K, Okumiya T, Sugiura T, Takahashi N, Yamamoto Y, Kikuchi S, Fujii K, Otagaki M, Shiojima I. BMC Nephrol. 2012 Jun;27(6):2303-11. doi: 10.1093/ndt/gfr677. Mircera is used to treat anemia caused by chronic kidney disease in adults, or in children at least 5 years old who are on hemodialysis. After a titration period, average time spent on anemia treatment over a 3 month period will be evaluated. . Further exploration of the relationship between DA and PEG-Epo doses using the BlandAltman method [10], which circumvents the limitations of the regression method in this type of investigation, indicated that the variability in the dose differences increased as doses increased, while the level of concordance decreased with increasing ESA dose. Over the last 25years, several originator and biosimilar ESAs have been introduced for the management of CKD anemia, starting with the first generation short-acting recombinant erythropoietin agents (epoetin alfa and beta) and latterly with two longer-acting molecules, darbepoetin alfa (DA) and methoxy polyethylene glycol-epoetin beta (PEG-Epo), which combine a significantly increased half-life and lower binding affinity for the EPO receptor, allowing them to stimulate erythropoiesis for longer periods and to be administered less frequently [5, 6]. Secondary outcomes included Hb concentrations and ESA use during the study period, and the incidence of red blood cell (RBC) transfusions. Empirical methods to calculate an erythropoiesis-stimulating agent dose conversion ratio in nondialyzed patients with chronic kidney disease.

In these hemodialysis patients switched from DA to PEG-Epo the DCR was 1.17 and 1.21 after accounting for the effect of transfusions. Epub 2014 Nov 1. Do not increase the dose more frequently than once every 4 weeks. AFFIRM (Aranesp Efficiency Relative to Mircera) was a retrospective, multi-site, observational study designed to estimate the population mean maintenance dose conversion ratio [DCR; dose ratio achieving comparable hemoglobin level (Hb) between two evaluation periods] in European hemodialysis patients whose treatment was switched from DA to PEG-Epo.

The remaining enrolment was at four sites divided between three other countries. By definition, the DCR could not be calculated for patients ineligible for the DCR analysis as these did not have the necessary parameters recorded in both EPs. Reasons for exclusion of 96 enrolled patients from the DCR analysis are presented in Fig. 1:1 reference line, BlandAltman analysis of agreement between, BlandAltman analysis of agreement between pre- and post-switch erythropoiesis-stimulating agent dose ( n, Hemoglobin level and weekly equivalent erythropoiesis-stimulating agent dose during the 14-month observation period., Red blood cell transfusions pre- and post-switch, Summary of the last hemoglobin concentrations recorded within 14 days prior to red, MeSH NCI CPTC Antibody Characterization Program, Astor BC, Muntner P, Levin A, Eustace JA, Coresh J. In the month immediately prior to switch, the proportions of patients who had Hb below 10, 1012, and above 12g/dL were 7.3%, 54.4%, and 25.7%, respectively, with 12.6% missing. Methoxy polyethylene glycol-epoetin beta, sold under the brand name Mircera, is a long-acting erythropoietin receptor activator (CERA) used for the treatment of anaemia associated with chronic kidney disease.

The geometric mean DCR of PEG-Epo to DA was 1.17, rising to 1.21 when the effect of RBC transfusions was taken into account. There were 16 transfusion events in the pre-switch period and 48 post-switch, with a total of 34 units transfused pre-switch and 95 units in the post-switch period (Fig. Months 7 to 1 constituted the pre-switch period, with switch defined as the date of first administration of PEG-Epo, and Months +1 to +7 constituted the post-switch period. Do you wish to proceed? A single hemoglobin excursion may not require a dosing change. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks. Introduction: In recent years, the trend has been to use higher doses of epoetin alfa (eg, 60,000 U once per week), recognizing that MDS RBC precursors may have relative intrinsic resistance to EPO. AFFIRM demonstrated non-linearity of the dose relationship curve, with DCR decreasing as pre-switch DA dose increased. This medicine is not used to treat anemia caused by cancer medicines.

There were 16 transfusions and 34 units transfused in the pre-switch period, versus 48 transfusions and 95 units transfused post-switch. The distribution of transfusions (Fig. Article Use caution in patients with coexistent cardiovascular disease and stroke. Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality than other patients. At the moment forecasts for Mircera are $345m in 2015 rising to $552m in 2020, reflecting sales made outside the US. Last updated on Jul 26, 2022. Palmer SC, Saglimbene V, Mavridis D, Salanti G, Craig JC, Tonelli M, Wiebe N, Strippoli GF. Regression analysis indicated a non-linear relationship between pre- and post-switch ESA doses; DCR decreased with increasing pre-switch DA dose. aMutually exclusive categories; patients are censored in the following order: first at death post-switch, then at loss to follow-up post-switch, then at receipt of an ESA other than PEG-Epo, and finally lack of an Hb measurement in either or both EPs. Learn about Mircera, potential side effects, proper use and dosing, and popular alternatives. Do not use the prefilled syringe more than once. The number of transfusions and units transfused increased approximately threefold from the pre-switch to the post-switch period. No difference in conversion dosage could be determined between patients who were epoetin sensitive (<200 units/kg per week) or resistant (>200 units/kg per week, P = NS). 1:1 reference line indicates equal PEG-Epo and darbepoetin alfa doses.

All groups were assessed at the end of the study for safety and efficacy parameters. Drug class: Recombinant human erythropoietins. There is limited information published on switching erythropoiesis-stimulating agent (ESA) treatment for anemia associated with chronic kidney disease (CKD) from darbepoetin alfa (DA) to methoxy polyethylene glycol-epoetin beta (PEG-Epo) outside the protocol of interventional clinical studies. Excluding patients receiving a transfusion within 90days of or during either EP, the DCR was 1.21 (95% CI 1.09, 1.35). MIRCERA Classification: Erythropoiesis stimulating protein. ONLY administer MIRCERA intravenously in pediatric patients. Dialysis centers were expected to adhere to European Best Practice Guidelines for iron repletion [9]. Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit. 600 Units/kg subcutaneously in 4 doses administered 21, 14, and 7 days before surgery and on the day of surgery. 1 0 obj Dose by Weight Chart - Resourcehub Epogen Dosage Guide - Drugs.com Epogen, Procrit (epoetin alfa) dosing, indications, interactions ARANESP single-dose strengths can be combined 4,* You can more .

[3] It is the first approved, chemically modified erythropoiesis-stimulating agent (ESA). AFFIRM may therefore help to guide expectations around potential differences in ESA dose requirements when switching hemodialysis patients from DA to PEG-Epo, although the reported mean maintenance DCR is not intended to predict the dose conversion ratio at the individual patient level. If Hb exceeds a level needed to avoid RBC transfusions, withhold dose until Hb approaches a level where RBC transfusions may be required and reinitiate at a dose 40% below the previous dose. government site.
