HX575 was approved in the European Union in August 2007 as the first-ever biosimilar epoetin-α product. The present study extended the safety database on HX575 by monitoring adverse events (AEs) in clinical practice. Hemoglobin (Hb) levels and HX575 doses were recorded for the assessment of efficacy. This open, 6-month single-arm study was conducted in 10 European countries with a target enrollment of 1,500 patients with anemia due to chronic kidney disease (CKD). HX575 was intravenously (i.v.) administered aiming at an Hb target of 10 - 12 g/dl. Most patients (92.3%) had already received erythropoiesis stimulating agents (ESAs) treatment before enrolment into this study; the recorded treatments mainly comprised i.v. or subcutaneous (s.c.) administration of epoetin-α, epoetin-β or darbepoetin. The study period covered 770 patient years. The observed AE profile was in line with expectations for this patient population. Thrombotic vascular events (TVEs) were reported in 11.9% of patients (0.2612 per patient year). Tumor incidence was 1.4% (0.0299 per patient year). No subject developed anti-epoetin antibodies. Mean Hb levels were effectively maintained between 11.2 and 11.3 g/dl following the conversion from a broad spectrum of pre-study ESA treatments with stable overall mean i.v. HX575 doses. The proportion of patients within the Hb target range increased from 57.5% at baseline to 66.8% at study end.
