Longer-acting PEG-Epo contains a chemical bond between an amino group present in epoetin beta and methoxy polyethylene glycol (PEG) butanoic acid; the addition of PEG is responsible for an increase in serum half-life of epoetin beta, and in CKD patients on dialysis the terminal half-life of PEG-Epo after IV administration is 134h [6, 8]. The geometric mean DCR was 1.17 (95% CI 1.05, 1.29). After a titration period, average time spent on anemia treatment over a 3 month period will be evaluated.

Anemia of end-stage renal disease (ESRD). For the purposes of this policy, a conversion factor of 3 should be used to estimate hematocrit when only the hemoglobin is measured, e.g., hemoglobin of 10 g/dL is approximately equal to a hematocrit of 30%, a hemoglobin of 11 g/dL is . Excursions of Hb values above and below the range of 1012g/dL [9] were more common in the post-switch compared to the pre-switch period.

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. 2023 Springer Nature Switzerland AG. Due to the skewed nature of the dosing data, mean weekly ESA doses were reported using geometric means; these were derived by calculating the arithmetic mean of the data transformed on the natural logarithmic scale. Cochrane Database Syst Rev. Subscribe to Drugs.com newsletters for the latest medication news, new drug approvals, alerts and updates. Figure4 also displays the mean monthly Hb for those included in the DCR analysis over the study period. Among patients switched from DA to PEG-Epo, the mean monthly PEG-Epo dose was increased from 159g at the switch to 263g at Week 26 and 273g at Month 1112 [11]. RBC transfusions were reported in terms of number of transfusions and number of units transfused, using descriptive statistics. DA can be administered once a week (QW) or once every 2weeks (Q2W) to hemodialysis patients. The number of RBC transfusions and units transfused in the post-switch period was approximately threefold higher compared to the pre-switch period. Control hypertension prior to initiating and during treatment with Aranesp or EPOGEN. This was particularly evident in patients whose pre-switch EP weekly DA dose was higher than 100g.

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 as a substitute for red blood cell transfusions in patients who require immediate correction of anemia. ?z_IxD1&S&L)@g7NI\H |a_,I17KFu[7+n h?b}xqm5Ed]N8+3ei^Rh/0up20]S=NoPAN$Z$L+u'Hp5v;'QyBQT 8}"{=xVqe)gR&yOs^sfT#B cf#xF`=bXMdCV?s&KS|`q9HT=,[='q6s1UE J$KxBE hg*~'ct'p|YTs1c->uLd_614J)q)g>QR`~*B9GewhNBPs j

Vifor (International) Inc. MIRCERA- methoxy polyethylene glycol-epoetin Regardless of possible differences in their clinical characteristics it should be borne in mind that patients were not selected for inclusion in the DCR analysis on the basis of their fulfilling any clinical, Hb or ESA dose requirements: all patients who had Hb measurements in both EPs, a DA dose in the pre-switch EP and a PEG-Epo dose in the post-switch EP were eligible for inclusion. Aranesp (darbepoetin alfa) Epogen (epoetin alfa) Mircera . MIRCERA has an approximate molecular weight of 60 kDa. Hemoglobin level and weekly equivalent erythropoiesis-stimulating agent dose during the 14-month observation period. 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]. 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.
Comparison Among Erythropoietin Stimulating Agents In particular, the likelihood of a transfusion during the post-switch period was significantly higher in patients with a dose ratio below 1 at switch. Accessibility Part of Springer Nature. 2 0 obj
Conversion from Epoetin alfa or Darbepoetin alfa to Mircera in Adult Patients with CKD Mircera can be administered once every two weeks or once monthly to patients whose hemoglobin has been stabilized by treatment with an ESA (see Table 1). 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. The pre-transfusion Hb concentrations were similar for transfusions occurring both pre- and post-switch (Fig. All groups were assessed at the end of the study for safety and efficacy parameters. methoxypolyethylene glycol-epoetin beta (meh-thok-see-pah-lee-eh-thih-leen gly-kol ee-poh-eh-tin bay-ta) , Mircera (trade name) Classification Therapeutic: antianemics Pharmacologic: hormones Pregnancy Category: C Indications Anemia due to chronic renal failure.

Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events. Am J Kidney Dis. Epoetin alfa was the first rhEPO produced and approved for pharmaceutical use, followed by several related products and by newer ESAs with the same mechanism but more prolonged action. 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. 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. The geometric mean weekly ESA doses were 24.1g DA in the pre-switch EP and 28.6g PEG-Epo in the post-switch EP.
