Introduction: a Mutually exclusive categories; patients are censored in the following, Analysis of relationship between pre- and post-switch erythropoiesis-stimulating agent dose. Do not use the prefilled syringe more than once. Mircera is administered by subcutaneous (SC) or intravenous (IV) injection (2.2). Randomized clinical studies have reported data on switching from DA to PEG-Epo (Stabilizing haemoglobin TaRgets in dialysis following IV C.E.R.A. A BlandAltman analysis [10] was also performed to assess the agreement between ESA doses in the evaluation periods. Aranesp (darbepoetin alfa) Summary of product characteristics. Brand: Mircera. 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)]. Correct or exclude other causes of anemia (e.g., vitamin deficiency, metabolic or chronic inflammatory conditions, bleeding, etc.) Visit. Mean Hb was 11.5 g/dL in the pre-switch EP and 11.4 g/dL in the post-switch EP.

This paper presents the findings of a retrospective, multi-center, observational study of hemodialysis patients switched from DA to PEG-Epo for the treatment of anemia. The introduction of exogenous erythropoiesis-stimulating agents (ESAs) to clinical practice has transformed the care of patients with CKD, by ameliorating anemia, reducing transfusion requirements, and improving quality of life [4]. Individual patients could contribute multiple transfusions to these analyses. 2012;59:44451. endobj 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. 2022;53(5):333-342. doi: 10.1159/000523947. 2023 Springer Nature Switzerland AG. 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 . St. Gallen, Switzerland: Vifor (International) Inc.; June 2018. Canaud B, Mingardi G, Braun J, et al. Finally, our study indicates that the risk of transfusion was higher in the post-switch compared with the pre-switch period, with an approximate threefold rise observed in the number of transfusions and units transfused post-switch. Locatelli F, Aljama P, Barany P, et al. \ab/`IR 4%jI ^w7qQNA Tq Wz.oVfCVBT{h*>\\3u#P@"wW7|pIMB7 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. This was particularly evident in patients whose pre-switch EP weekly DA dose was higher than 100g. Disposition of patients. 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. Unable to load your collection due to an error, Unable to load your delegates due to an error. The dose of Mircera, given as a single intravenous or subcutaneous injection, should be based on the total weekly ESA dose at the time of conversion. DCR was calculated for patients with Hb and ESA data available in both evaluation periods (EP; Months 1 and 2 were defined as the pre-switch EP, and Months 6 and 7 as the post-switch EP). See Instructions for Use for complete instructions on the preparation and administration of Mircera. Dosing patterns, drug costs, and hematologic outcome in anemic patients with chronic kidney disease switching from darbepoetin alfa to epoetin alfa. Patients included in the analysis were less likely to be diabetic (32% vs. 40%), more likely to be receiving DA at a longer dosing interval (60% vs. 73% at QW; 19% vs. 3% less frequently than Q2W), and received a lower geometric mean weekly dose of DA during the pre-switch EP (24.1 vs. 37.7g). Bookshelf _____ (if . 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 Methoxy polyethylene demonstrated that the dose efficiency after SC and IV ad- glycol-epoetin b (PEG-epoetin b; Mircera; F.

Summary of the last hemoglobin concentrations recorded within 14days prior to red blood cell transfusions pre- and post-switch. Evaluate the iron status in all patients before and during treatment. MIRCERA Classification: Erythropoiesis stimulating protein. Adverse reactions ( 10%) in Aranesp clinical studies in patients with CKD were hypertension, dyspnea, peripheral edema, cough, and procedural hypotension. ?Ij{JVv:oC*#]}V#$M_T.zC>~] L%lq[Tn`QbWB./@ClVgrk)U-j#(0(D MIRCERA Interactions: May require increased anticoagulation (heparin) during hemodialysis. % Article MIRCERA (methoxy polyethylene glycol-epoetin beta) is the first erythropoiesis-stimulating agent (ESA) approved by FDA for once-monthly administration. AFFIRM demonstrated non-linearity of the dose relationship curve, with DCR decreasing as pre-switch DA dose increased. Please click the OK button below to continue. The majority of patients who were transfused during the pre- and post-switch observation periods had Hb 10g/dL within the 14days prior to transfusion; only 1 patient during each period had Hb >11g/dL within the 14-day pre-transfusion interval. This compares with a 35% decline in Epogen sales during the same period to $1.13bn, as competition from Mircera and biosimilars, like by Sandoz' Binocrit, reach the markets. 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]. Patients stable on intravenous (iv) epoetin alfa will be randomized either to receive standard of care therapy (epoetin alfa (iv) 3 times weekly), or to receive Mircera 120-360 micrograms (iv), monthly. aranesp to retacrit conversiontuto amigurumi grenouille au crochet. Treatment for Anaemia [STRIATA] [8] and comPArator sTudy of C.E.R.A. The initial conversion factor was 200:1. Regression analysis indicated a non-linear relationship between pre- and post-switch ESA doses; DCR decreased with increasing pre-switch DA dose.
