Methoxy polyethylene glycol-epoetin beta injection is used to treat anemia in adults with chronic kidney disease (CKD) who may or may not be on dialysis or in children with CKD who are on dialysis. Lancet. Do not increase the dose more frequently than once every 4 weeks. The aims of the Aranesp Efficiency Relative to Mircera (AFFIRM) study were primarily to estimate the maintenance dose conversion ratio (DCR) of PEG-Epo to DA in a population of European hemodialysis patients switched from DA to PEG-Epo and with comparable mean hemoglobin (Hb) in the pre- and post-switch periods, and secondarily to investigate The enrolling dialysis centers were situated in France, Germany, Spain and the UK, and each was expected to enroll a minimum of 20 patients into the study.

I certify that I am a healthcare professional in the US. endobj Conclusion: In patients on hemodialysis receiving ESAs, conversion from epoetin alfa to darbepoetin alfa was associated with an approximate and persistent reduction of 65% of the required dose. Following initiation of therapy and after each dose adjustment, monitor hemoglobin weekly until the hemoglobin level is stable and sufficient to minimize the need for RBC transfusion. For patients who do not respond adequately, if the hemoglobin has not increased by more than 1 g/dL after 4 weeks of therapy, increase the dose by 25%. Eschbach JW, Adamson JW. Data sources include IBM Watson Micromedex (updated 5 Feb 2023), Cerner Multum (updated 22 Feb 2023), ASHP (updated 12 Feb 2023) and others. PubMed PMC 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]. Janet Addison is an employee of Amgen with Amgen stock options. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks.

The odds ratio for receiving a transfusion was twice as high in patients switched at a dose ratio less than 1 when compared to those switched at 1:1 or higher. Eligible patients were randomized, either to continue on the previous regimen of Epoetin, or to receive Darbepoetin alfa or continuous erythropoietin receptor activator (C.E.R.A) for a total period of 40 weeks. Descriptions. However, healthcare-resource utilization and cost data were not collected in this study, preventing comparison of these variables between the pre-switch and post-switch periods. Mircera would also have competed with Aranesp and with Procrit . x]r9r}W#k Methods: The MHRA is aware of very rare cases of severe cutaneous adverse reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, in patients treated with erythropoietins; some cases were fatal.

Secondly, the DCR was calculated on a subset of patients which constituted approximately two-thirds of the total enrolled. On June 7, 2018, the Food and Drug Administration approved methoxy polyethylene glycol-epoetin beta (Mircera, Vifor Pharma Inc.) for the treatment of pediatric patients 5 to 17 years of age on. 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. 2022;53(5):333-342. doi: 10.1159/000523947. EPOGEN from multidose vials contains benzyl alcohol and is contraindicated in neonates, infants, pregnant women, and lactating women. The regression analysis that examined the relationship between mean weekly ESA doses in the two evaluation periods indicated that the DCR is not linear; a significant (P=0.008) quadratic term was observed in the regression analysis, indicating that the predicted DCR decreased at higher pre-switch doses of DA (Fig. 3 DOSAGE FORMS AND STRENGTHS. The intravenous route is recommended for patients on hemodialysis because the intravenous route may be less immunogenic. | DOWNLOAD SIZE: The geometric mean weekly ESA doses were 24.1 g DA in the pre-switch EP and 28.6 g PEG-Epo in the post-switch EP. Most frequent adverse reactions (5%) in adult patients with CKD treated with MIRCERA. The WHO has set the daily-defined dose (DDD) for epoetin beta and darbepoetin at 1000 U and 4.5 g respectively, which gives a conversion factor of 222:1 . In controlled clinical trials of patients with CKD comparing higher hemoglobin targets (13 to 14 g/dL) to lower targets (9 to 11.3 g/dL), ESAs increased the risk of death, myocardial infarction, stroke, congestive heart failure, thrombosis of hemodialysis vascular access, and other thromboembolic events in the higher target groups. 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).
