Once the hemoglobin has been stabilized, MIRCERA, If the hemoglobin level exceeds 10 g/dL, reduce or interrupt the dose of MIRCERA. Packaging Type: Injection. 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 Do not pool unused portions from the prefilled syringes. Methoxy polyethylene glycol-epoetin beta, the active substance of MIRCERA, is a continuous erythropoietin receptor activator that shows a different activity at the receptor level characterized by a slower association to and faster dissociation from the receptor, a reduced specific activity in vitro with an increased activity in vivo, as well as an increased half-life, in contrast to . The long-acting r-HuEPO methoxy polyethylene glycol-epoetin beta (Mircera) has been associated with a risk of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) following a. Following administration, remove the needle from the injection site and then release the plunger to allow the needle guard to move up until the entire needle is covered.

PMC The primary outcome measure, the geometric mean maintenance DCR, was calculated to be 1.17 (95% CI 1.05, 1.29). Treatment: Treat to anemia in people with chronic kidney disease. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. Box 1557, 6301, Zug, Switzerland, Amgen (UK) Limited, 240 Cambridge Science Park, Milton Road, Cambridge, UK, You can also search for this author in Would you like email updates of new search results? Google Scholar. 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. Action Stimulates erythropoesis (production of red blood cells). 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. 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. See Instructions for Use for complete instructions on the preparation and administration of Mircera. Conversion from Epoetin alfa or Darbepoetin alfa to Mircera in Pediatric Patients with CKD Treated with Hemodialysis Administer Mircera intravenously once every 4 weeks to pediatric patients (ages 5 to 17 years) whose hemoglobin level has been stabilized by treatment with an ESA. 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.

Disclaimer. Aranesp (darbepoetin alfa) is indicated for the treatment of anemia due to chronic kidney disease (CKD), including patients on dialysis and patients not on dialysis. 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. 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. It is not known if Mircera is safe and effective in children younger than 5 years of age. NCI CPTC Antibody Characterization Program, Astor BC, Muntner P, Levin A, Eustace JA, Coresh J. 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).

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. 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. If severe anemia and low reticulocyte count develop during treatment with Aranesp or EPOGEN, withhold Aranesp or EPOGEN and evaluate patients for neutralizing antibodies to erythropoietin. 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. 2012;59:444451. For administration using the prefilled syringe, the plunger must be fully depressed during injection in order for the needle guard to activate. When adjusting therapy consider hemoglobin rate of rise, rate of decline, ESA responsiveness and hemoglobin variability. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Anemia of chronic kidney disease (CKD) becomes increasingly prevalent and severe as kidney function declines [1], with over 90% of patients who require renal replacement therapy becoming anemic [2]. This has been reported predominantly in patients with CKD receiving ESAs by subcutaneous administration.

There were 16 transfusions and 34 units transfused in the pre-switch period, versus 48 transfusions and 95 units transfused post-switch. 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. 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. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks. 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.
