Background: Limited prospective data are available on the long-term safety of darbepoetin alfa (DA) for treating anemia in children with chronic kidney disease (CKD). Methods: In this prospective, phase IV, observational registry study, children ≤16 years of age with CKD anemia and receiving DA were observed for ≤2 years. Adverse events (AEs), DA dosing, hemoglobin (Hb) concentrations, and transfusions were recorded. Results: A total of 319 patients were included in the analysis (mean age, 9.1 years), 158 (49.5 %) of whom were on dialysis at study entry. Of 434 serious AEs reported in 162 children, the most common were peritonitis (10.0 %), gastroenteritis (6.0 %), and hypertension (4.1 %). Six patients (1.9 %) died (unrelated to DA). Four patients (1.3 %) experienced six serious adverse drug reactions. The geometric mean DA dose range was 1.4-2.0 μg/kg/month. Mean baseline Hb concentration was 11.1 g/dl; mean values for children receiving and not receiving dialysis at baseline ranged between 10.9 and 11.5 g/dl and 11.2-11.7 g/dl, respectively. Overall, 48 patients (15.0 %) received ≥1 transfusion. Conclusions: No new safety signals for DA were identified in children receiving DA for CKD anemia for ≤2 years. Based on Hb concentrations and transfusion requirements, DA was effective at managing anemia in these patients. [ABSTRACT FROM AUTHOR]
