Hemoglobin maintenance and dosing strategies using intravenous continuous erythropoietin receptor activator in Japanese hemodialysis patients.

Methoxy polyethylene glycol-epoetin beta, a continuous erythropoietin receptor activator (CERA), is reported to be effective in managing renal anemia but there is little data about CERA in Japan. This study aimed to ascertain the effects of CERA in Japanese hemodialysis patients and the appropriate starting dose of CERA when switching from other erythropoiesis-stimulating agents. We switched 61 stable hemodialysis patients to 4-weekly intravenous CERA, from either epoetin beta (rHuEPO) or darbepoetin alpha (DA).
