MIRCERA is an erythropoiesis-stimulating agent (ESA) indicated for the treatment of anemia associated with chronic kidney disease (CKD) in: MIRCERA is not indicated and is not recommended for use: MIRCERA has not been shown to improve quality of life, fatigue, or patient well-being. 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. Mircera is not the same as epoetin alfa (Procrit, Epogen). The AFFIRM study was designed as a retrospective, longitudinal cohort analysis to estimate the DCR in a population of hemodialysis patients achieving comparable Hb after switching from IV DA to IV PEG-Epo in a real-world setting. By Month 7 post-switch, the proportions of patients with Hb in these ranges were 9.7%, 48.1%, and 30.1%, respectively. Clin Kidney J.

The distribution of Hb values reported within the 14days prior to transfusion was described; if multiple Hb values were recorded, the value closest to the transfusion date was utilized. doi: 10.1053/j.ajkd.2011.11.013. 2008;23:365461. Data were collected from 7months before until 7months after switching treatment. Anemia response to Methoxy Polyethylene Glycol-Epoetin Beta (Mircera) versus Epoetin Alfa (Eprex) in patients with chronic Kidney disease on Hemodialysis Published: September 05, 2017 42/47 is common in patients with a GFR below 30 ml/min/1.73m2 and contributes to many of the speciic symptoms of CKD. 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). In controlled clinical trials, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and the risk of deep venous thrombosis (DVT) in patients undergoing orthopedic procedures. 2002;162:14018. W\iA* 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. government site.

Administer MIRCERA intravenously once every 4 More ways to get app. Correct or exclude other causes of anemia (e.g., vitamin deficiency, metabolic or chronic inflammatory conditions, bleeding, etc.) 33 Dose. The conversion rate was 354:1 in patients requiring high (>200 IU/kg/week) doses of epoetin and 291:1 in patients requiring low doses. Methoxy polyethylene glycol-epoetin (Mircera ) will be increased and decreased in 1-step or 2-step increments, based on scale above. Goodkin DA, Zhao J, Cases A, Nangaku M, Karaboyas A. 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]. endobj Most frequent adverse reactions (5%) in adult patients with CKD treated with MIRCERA. Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in These findings were observed in studies of patients with advanced head and neck cancer receiving radiation therapy, in patients receiving chemotherapy for metastatic breast cancer or lymphoid malignancy, and in patients with non-small cell lung cancer or various malignancies who were not receiving chemotherapy or radiotherapy. Excluding patients receiving a transfusion within 90 days of or during either EP, the DCR was 1.21 (95% CI 1.09, 1.35). 5) shows that most transfusions occurred in the first 4months post-switch. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Amgen's two anemia drugs, Epogen and Aranesp, had sales of $6.6 billion last year, nearly half the company's total revenue. More severe cases were recorded with long-acting agents (darbepoetin alfa and methoxy polyethylene glycol-epoetin beta). Pharmacokinetic studies have shown that the meanSD terminal half-life of DA is 217.5h when administered intravenously (IV) [7]. 5). Accounting for the effect of transfusion, the DCR was 1.21 (95% CI 1.09, 1.35). . Secondary outcomes included Hb concentrations and ESA use during the study period, and the incidence of red blood cell (RBC) transfusions. <>/Metadata 444 0 R/ViewerPreferences 445 0 R>> The PATRONUS study, in which stable hemodialysis patients receiving IV DA were randomized either to QM PEG-Epo or to Q2W DA for 26weeks [11], described an increase in post-switch dose requirement.
