What is Methoxy polyethylene glycol epoetin beta

Methoxy polyethylene glycol epoetin beta (MPG-epoetin beta), also called continuous erythropoietin receptor activator, is a long-acting synthetic erythropoietin protein approved for the treatment of anemia associated with chronic kidney disease.

Studies in patients with chronic kidney disease who were either dialysis-dependent or dialysis-independent have shown similar efficacy in achieving target hemoglobin concentrations and reducing red blood cell transfusion dependence as comparator erythropoiesis-stimulating agents (ESAs).

The primary advantage of MPG-epoetin beta versus other ESAs is that it can be dosed less frequently (up to every 4 weeks) due to its extremely long half-life. MPG-epoetin beta should only be used in patients with chronic kidney disease and should not be used to treat cancer-related anemia.

A dose-ranging study of MPG-epoetin beta in patients with cancer was terminated early because of more deaths in the patients receiving MPG-epoetin beta compared to another ESA.


  • anemia
  • Evaluate the iron status in all patients before and during treatment. Administer supplemental iron when the serum ferritin is less than 100 mcg/L or when serum transferrin saturation is less than 20%.
  • Correct or exclude other causes of anemia such as vitamin deficiency, metabolic or chronic inflammatory conditions, and bleeding before initiating methoxy polyethylene glycol-epoetin beta (MPG-epoetin beta). Monitor hemoglobin (Hgb) weekly until stable and sufficient to minimize the need for red blood cell (RBC) transfusions.
  • MPG-epoetin beta has not been shown to improve symptoms, physical functioning, or health-related quality of life.
  • MPG-epoetin beta is not indicated and is not recommended:
    • In the treatment of anemia due to cancer chemotherapy
    • As a substitute for RBC transfusions in patients who require immediate correction of anemia
  • In adult patients with chronic kidney disease on dialysis, initiate when the Hgb concentration is less than 10 g/dL.
  • In adult patients with chronic kidney disease not on dialysis, initiate when the Hgb is less than 10 g/dL, the rate of Hgb decline indicates the likelihood of requiring a RBC transfusion, and reducing the risk of alloimmunization and/or other RBC transfusion-related risks is a goal.
