Randomized Controlled Trial
Oral roxadustat three times weekly in ESA-naïve and ESA-converted patients with anemia of chronic kidney disease on hemodialysis: Results from two phase 3 studies.
Roxadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor approved in China for anemia of dialysis-dependent chronic kidney disease (CKD). Japanese hemodialysis patients with anemia of CKD previously naïve to, or converted from, erythropoiesis-stimulating agents (ESAs) were enrolled in two open-label, noncomparative studies of titrated oral roxadustat administered three times weekly. ESA-naïve patients (n = 75) were randomized to roxadustat (initial dose, 50 or 70 mg) for 24 weeks; ESA-converted patients (n = 164) were assigned to roxadustat (initial dose, 70 or 100 mg based on prior ESA dose) for 52 weeks. ⋯ Nasopharyngitis was the most common TEAE. Two deaths, considered unrelated to roxadustat, occurred in the ESA-Converted Study. Roxadustat effectively corrected and maintained Hb, regardless of previous ESA treatment, in Japanese anemic CKD patients on hemodialysis.

Iron and erythropoietin deficiencies are determinants of anemia in chronic kidney disease. In hemodialysis (HD) patients, intravenous (IV) iron is associated with a greater hemoglobin (Hb) production and better erythropoietin response but may be associated to hypersensitivity reaction. After the 2013 European Medicines Agency report regarding early detection/management of iron allergic reactions, IV iron administration dramatically reduced in Italian Hemodialysis-Limited-Assistance-Centre (HD-CAL) where a physician is present only once a week. ⋯ Six months of FCM IV treatment once a week increased ferritin and Hb compared to sodium ferric gluconate once a week leading to decreased erythropoietin consumption from 24 000 to 15 000 U/patient/week with an erythropoietin annual expense reduction. No blood transfusions, gastrointestinal intolerance or other adverse effects were reported. The FCM IV administration protocol for our HD-CAL patients was safe and no adverse events were reported, resulting in significantly increased ferritin, transferrin saturation, and Hb levels, reduction of erythropoietin requirements, and consequently reduction of erythropoietin expenses.
