This was particularly evident in patients whose pre-switch EP weekly DA dose was higher than 100g. Nephrol Dial Transplant. eCollection 2020 Jun. 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. What is the practical conversion dose when changing from epoetin alfa 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). Patients were required to fulfill the following criteria for study entry: switched from treatment with DA to treatment with PEG-Epo at least 7months before study enrollment; receipt of hemodialysis for at least 12months prior to switching; receipt of IV DA for at least 7months immediately prior to switching; receipt of at least 1 dose of PEG-Epo after switching; and provision of informed consent, according to local requirements. Dose Conversion Ratio in Hemodialysis Patients Switched from Darbepoetin Alfa to PEG-Epoetin Beta: AFFIRM Study. Aranesp (darbepoetin alfa) Epogen (epoetin alfa) Mircera . 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 . 1. 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). m+KqXAXOkS@,1C0VgzXzeWU},4 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. No test of statistical significance was performed on any of the clinical characteristics. 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. PRCA has also been reported in patients receiving ESAs for anemia related to hepatitis C treatment (an indication for which Aranesp and EPOGEN are not approved). Excluding patients receiving a transfusion within 90 days of or during either EP, the DCR was 1.21 (95% CI 1.09, 1.35). Article -, Macdougall IC. The majority of patients with CKD will require supplemental iron during the course of ESA therapy. Switch from epoetin to darbepoetin alfa in hemodialysis: dose For administration using the prefilled syringe, the plunger must be fully depressed during injection in order for the needle guard to activate. 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.

Aranesp Dosing Calculator75 mcg/kg as an IV or SC injection once every 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. Cases of PRCA and of severe anemia, with or without other cytopenias that arise following the development of neutralizing antibodies to erythropoietin have been reported in patients treated with Aranesp or EPOGEN. -, Kazmi WH, Kausz AT, Khan S, et al. Do not use any prefilled syringes exhibiting particulate matter or a coloration other than colorless to slightly yellowish. Patients were excluded if they had participated in any interventional study within 30days before the 7-month period preceding the switch or at any subsequent time up to 7months after the switch. Optimizing the use of erythropoietic agentspharmacokinetic and pharmacodynamic considerations. Individualize dosing and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions [see Warnings and Precautions (5.1)]. Methods: endobj Regression analysis indicated a non-linear relationship between pre- and post-switch ESA doses; DCR decreased with increasing pre-switch DA 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. In the month immediately prior to switch, the proportions of patients who had Hb below 10, 1012, and above 12g/dL were 7.3%, 54.4%, and 25.7%, respectively, with 12.6% missing. 2023Vifor (International) Inc.

Article 1MIRCERA [prescribing information]. Not all pack sizes may be marketed. Logistic regression was used to estimate an odds ratio comparing the number of patients receiving an RBC transfusion in the post-switch period relative to their dose ratio at switch (<1 vs. 1).

Patients were then switched to fortnightly darbepoetin alfa dosing treatments; the existing weekly dose being doubled and Hb levels fell from 125 to 110 g/L (P < 0.0001), despite an increase in the mean dose from 44.9 to 47.5 . The pre-transfusion Hb concentrations were similar for transfusions occurring both pre- and post-switch (Fig. Examine each prefilled syringe for the expiration date. This study and the article processing charges were funded by Amgen Europe GmbH, Zug, Switzerland. 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.

Although the reasons for transfusion were not recorded, the pre-transfusion Hb concentrations within 14days prior to transfusion remained similar for transfusions occurring both pre- and post-switch. If the hemoglobin rises rapidly (e.g., more than 1 g/dL in any 2-week period), reduce the dose of MIRCERA. Anemia of end-stage renal disease (ESRD) Kidney Int.

Mircera may be used alone or with other medications. 5) shows that most transfusions occurred in the first 4months post-switch. 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 Mutually exclusive categories; patients are censored in the following, Analysis of relationship between pre- and post-switch erythropoiesis-stimulating agent dose.
