Molidustat, an orally administered hypoxia-inducible factor prolyl-hydroxylase inhibitor, is under development for the treatment of anemia of CKD. This 24-week, phase 3, single-arm, multicenter study evaluated the efficacy and safety of molidustat in Japanese patients with renal anemia who were undergoing hemodialysis and who were not receiving an erythropoiesis-stimulating agent. Twenty-five patients received molidustat at a starting dose of 75 mg once daily, which was adjusted to maintain a Hb target of ≥10.0 to <12.0 g/dL. ⋯ No adverse events of special interest were reported. Treatment with dose-titrated molidustat for 24 weeks was well tolerated in Japanese patients undergoing hemodialysis, and no new safety signal was observed. Clinicaltrials.gov identifier: NCT03351166.

Randomized Controlled Trial Multicenter Study
Intermittent Oral Dosing of Roxadustat in Peritoneal Dialysis Chronic Kidney Disease Patients with Anemia: A Randomized, Phase 3, Multicenter, Open-Label Study.
Roxadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor developed to treat anemia in chronic kidney disease (CKD) patients. This Phase 3, randomized, open-label, 24-week study investigated the efficacy and safety of roxadustat in Japanese CKD patients with anemia on peritoneal dialysis (PD) who were previously treated or not treated with erythropoiesis stimulating agents (ESAs). Patients not previously receiving ESA (ESA-Naïve group) were randomized to roxadustat at a starting dose of 50 or 70 mg three times weekly; patients previously receiving ESA (ESA-Converted group) switched from ESA to roxadustat 70 or 100 mg three times weekly depending on the prior ESA dose. ⋯ Average Hb levels (weeks 18-24) were 11.05 g/dL (95% CI: 10.67-11.42; ESA-Naïve) and 10.93 g/dL (95% CI: 10.73-11.13; ESA-Converted). Common TEAEs included nasopharyngitis and back pain. Roxadustat was well tolerated and effective in maintaining target Hb levels in CKD patients on PD who were previously treated or not treated with ESA.

Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor approved in Japan for the treatment of anemia in patients with chronic kidney disease (CKD). This phase 3, open-label, single-arm study evaluated the efficacy and safety of vadadustat in 24 Japanese patients with CKD-associated anemia on hemodialysis who were not receiving erythropoiesis-stimulating agents (ESAs). Patients received vadadustat for 24 weeks; the starting dose was 300 mg/day and doses were adjusted to achieve the target hemoglobin (Hb) range of 10.0-12.0 g/dL. ⋯ The most common adverse event was shunt stenosis (25.0%). Adverse drug reactions (diarrhea and vomiting) occurred in two patients (8.3%) and the severity was mild. Vadadustat increased and maintained Hb levels within the target range and was generally well-tolerated in Japanese patients with anemia on hemodialysis not receiving ESAs.

Comparative Study
In Vitro Evaluation of Resistance and Warming Performance of a Small Blood Warmer on a Continuous Renal Replacement Therapy Circuit.
Children on extracorporeal devices are at increased risk of hypothermia and require circuits with lower extracorporeal volume to avoid blood priming. We performed an in vitro study of the enFlow blood warmer to assess its warming performance and impact on circuit resistance at a high blood flow rate. The enFlow was added on the return line of a continuous renal replacement therapy circuit in a closed circuit primed with expired packed red blood cells (40% Hct). ⋯ Combining both warmers achieved a higher post-warmer temperature between 35.1 and 36.5°C. The enFlow can warm blood at high flow rates with minimal extracorporeal volume increase (~5 mL) and improve hypothermia prevention but may have resistance issues at the highest flows. The use of this device could benefit pediatric practice where smaller extracorporeal volumes are needed and patients are at increased risk of hypothermia.
