Background: Molidustat, a novel hypoxia-inducible factor-prolyl hydroxylase inhibitor, is being investigated for the treatment of anemia associated with chronic kidney disease (CKD). The efficacy and safety of molidustat were recently evaluated in three 16-week phase 2b studies. Here, we report the results of two long-term extension studies of molidustat. Methods: Both studies were parallel-group, open-label, multicenter studies of ≤36 months’ duration, in patients with anemia due to CKD, and included an erythropoiesis-stimulating agent as active control. One study enrolled patients not receiving dialysis (n = 164), and the other enrolled patients receiving hemodialysis (n = 88). The primary efficacy variable for both studies was change in blood hemoglobin (Hb) level from baseline to each post-baseline visit, and safety outcomes included adverse events (AEs). Results: In patients not on dialysis, the mean ± SD Hb concentrations at baseline were 11.28 ± 0.55 g/dL for molidustat and 11.08 ± 0.51 g/dL for darbepoetin. The mean ± SD blood Hb concentrations throughout the study (defined as mean of each patient’s overall study Hb levels) were 11.10 ± 0.508 and 10.98 ± 0.571 g/dL in patients treated with molidustat and darbepoetin, respectively. Similar proportions of patients reported at least one AE in the molidustat (85.6%) and darbepoetin (85.7%) groups. In patients on dialysis, mean ± SD Hb levels at baseline were 10.40 ± 0.70 and 10.52 ± 0.53 g/dL in the molidustat and epoetin groups, respectively. The mean ± SD blood Hb concentrations during the study were 10.37 ± 0.56 g/dL in the molidustat group and 10.52 ± 0.47 g/dL in the epoetin group. Proportions of patients who reported at least one AE were 91.2% in the molidustat group and 93.3% in the epoetin group. Conclusions: Molidustat was well tolerated for up to 36 months and appears to be an effective alternative to darbepoetin and epoetin in the long-term management of anemia associated with CKD.

Abstract Background and Aims Hyperphosphatemia in chronic kidney disease (CKD) patients is associated with adverse outcomes, including vascular calcification, increasing risks of disease progression and even death. Sevelamer carbonate have been approved in Europe for phosphate lowering treatment in pre-dialysis CKD patient, its efficacy and safety in Chinese CKD hyperphosphatemia patients are not previously reported. Method This was a phase III, multi-center, randomized, double blind, placebo-controlled, balanced (1:1, sevelamer: placebo) parallel-group study to evaluate the efficacy and safety of sevelamer carbonate versus placebo over 8 weeks’ duration in hyperphosphatemic CKD patients not on dialysis in China (Registration number NCT03001011). The primary objective of this study is to demonstrate efficacy of sevelamer carbonate tablets in the reduction of serum phosphorus in hyperphosphatemia in patients with chronic kidney disease (CKD) not on dialysis. Results In all, 202 patients were randomized (sevelamer, n=101; placebo, n=101); mean age was 50.7 years, 53.5% were male and the mean time of CKD diagnosis was 3.4 years with mean eGFR 7.5 ml/min/1.73 m2. The baseline phosphorous were 2.13±0.35 mmol/L and 2.12±0.37 mmol/L in sevelamer and placebo group, respectively. The mean serum phosphorous decreased significantly in patients treated with sevelamer carbonate (-0.22±0.47 mmol/L) compared with placebo (0.05±0.44 mmol/L) (mean difference between sevelamer carbonate and placebo was -0.26 mmol/L, P<0.0001). When compared with placebo, sevelamer carbonate significantly reduced serum total cholesterol (-0.90±0.85 vs. -0.06±0.68 mmol/L, P<0.0001), low-density lipoprotein cholesterol (-0.94±0.72 vs. -0.04±0.58 mmol/L, P<0.0001) and calcium-phosphorous product (-0.48±0.97 vs. 0.05±0.81 mmol2/L2) from baseline to week 8. Serum iPTH was not significantly changed in sevelamer carbonate group compared with placebo group (-9.60±136.00 vs. 7.61±141.92 ng/L, P=0.83). Sevelamer carbonate was well tolerated with 83.27% compliance compared with 82.19% compliance in placebo arm. Average dose of sevelamer carbonate was 7.51 g/d at the end of study and 4.52 g/d across the study. Adverse events experienced by patients in sevelamer carbonate and placebo group were similar. Conclusion This study demonstrated that sevelamer carbonate has produced a significant reduction of serum phosphorous, and is safe and tolerated in Chinese pre-dialysis CKD patients with hyperphosphatemia.

<b><i>Introduction:</i></b> Ferric citrate (FC) is indicated as an oral iron replacement for iron deficiency anemia in adult patients with chronic kidney disease (CKD) not on dialysis. The recommended starting dose is one 1-g tablet three times daily (TID). This study investigated long-term efficacy and safety of different FC dosing regimens for treating anemia in nondialysis-dependent CKD (NDD-CKD). <b><i>Methods:</i></b> In this phase 4, randomized, open-label, multicenter study, patients with anemia with NDD-CKD (estimated glomerular filtration rate, ≥20 mL/min and &#x3c;60 mL/min) were randomized 1:1 to one FC tablet (1-g equivalent to 210 mg ferric iron) TID (3 g/day) or 2 tablets twice daily (BID; 4 g/day). At week 12, dosage was increased to 2 tablets TID (6 g/day) or 3 tablets BID (6 g/day) in patients whose hemoglobin (Hb) levels increased &#x3c;0.5 g/dL or were &#x3c;10 g/dL. Primary endpoint was mean change in Hb from baseline to week 24. <b><i>Results:</i></b> Of 484 patients screened, 206 were randomized and 205 received FC. Mean (standard deviation) changes from baseline in Hb at week 24 were 0.77 (0.84) g/dL with FC TID 3 g/day and 0.70 (0.98) g/dL with FC BID 4 g/day. <b><i>Discussion/Conclusions:</i></b> FC administered BID and TID for 48 weeks was safe and effective for treating anemia in this population, supporting potentially increased dosing flexibility.

♦BackgroundPeginesatide is a novel, synthetic, peptide-based pegylated erythropoiesis-stimulating agent that is designed specifically to stimulate the erythropoietin receptor. The purpose of the present study was to assess, for the first time, the efficacy and safety of peginesatide in chronic kidney disease (CKD) patients receiving peritoneal dialysis (PD) and previously on epoetin treatment.♦MethodsIn this open-label multicenter study, 59 PD patients with CKD were converted from epoetin (alfa or beta) to once-monthly peginesatide. Doses were titrated to maintain hemoglobin levels between 10 g/dL and 12 g/dL during the 25 weeks of the study. The primary endpoint was change from baseline in mean hemoglobin values during the evaluation period (weeks 20 – 25).♦ResultsThe mean hemoglobin value during the evaluation period was 11.3 ± 1.07 g/dL, and the mean change from baseline was 0.10 ± 1.15 g/dL (95% confidence limits: –0.24, 0.44 g/dL). During the evaluation period, most patients maintained hemoglobin levels between 10 g/dL and 12 g/dL (63.0%) and within ±1.0 g/dL of baseline (60.9%). The median weekly epoetin dose at baseline was 96.0 U/kg, and the median starting peginesatide dose was 0.047 mg/kg. Forty-three patients (72.9%) completed the study. Six patients (10.2%) received red blood cell transfusions. The observed adverse event profile was consistent with underlying conditions in the PD patient population. The most common adverse event was peritonitis (20.3%), a complication commonly associated with PD. Four deaths occurred during the study (2 related to septic shock, and 1 each to myocardial ischemia and myasthenia gravis).♦ConclusionsIn this study, once-monthly peginesatide maintained hemoglobin levels in PD patients after conversion from epoetin.

Abstract Background Renin–angiotensin–aldosterone system (RAAS) inhibitors provide significant cardiorenal benefits with improved long-term outcomes for patients. This is most significant for patients receiving maximal RAAS inhibition, but some patients are unable to tolerate this therapy because of hyperkalaemia. Recently published National Institute for Health and Care Excellence (NICE) technology appraisal guidance recommended using sodium zirconium cyclosilicate (SZC) and patiromer for patients with chronic kidney disease (CKD) stage 3b to 5 or heart failure with reduced ejection fraction, who are not taking an optimised dosage of RAAS inhibitor because of hyperkalaemia. Objective Determine the impact of a locally produced guideline on effective implementation of NICE recommendation for use of SZC or patiromer to help maximise inhibition of the renin–angiotensin–aldosterone system within the general nephrology clinic. Methods A local guideline to practically support the implementation of recommendations made by NICE in the chronic use of new potassium binders was produced. One hundred sequential patients in a general nephrology clinic with non-immune chronic kidney disease (CKD 3 to 5) had their electronic records reviewed. Those with an indication for RAAS inhibition were identified. Results Of the 100 consecutive patients audited, 46 were female and 54 were male. The mean age of these patients was 64 and the mean estimated glomerular filtration rate (eGFR) was 33. Sixty-eight patients had an indication for being on RAAS inhibition with only 10 on maximal doses. Of the remaining 58 patients, 26 (45%) were limited by hyperkalaemia. Of these 26 patients, 12 of these patients (46%) had hyperkalaemia associated with an episode of acute kidney injury (AKI). Therefore, 14% of patients attending a general nephrology clinic were identified suitable for SZC and patiromer. Conclusions A significant proportion (14%) of unselected patients attending a general nephrology clinic were not on optimum RAAS inhibition due to hyperkalaemia. These patients would meet the criteria established within a working guideline for the implementation of the chronic use of SZC or patiromer and are likely to attain prognostic long-term benefit by using these new potassium binders to maximise RAAS inhibition. This analysis has implications for renal centres across the UK.

Abstract Background Intravenous (IV) iron is frequently used to treat iron deficiency/anemia in patients who are unable to tolerate oral iron or the oral iron is not sufficient toreplete iron requirements. However, safety concerns regarding the potential increase in oxidative stress and other adverse effects persist and it remains unclear whether all iron preparations are equivalent. Indeed, the comparative risk of adverse events with IV iron preparations has not been extensively assessed. We hypothesize that IV iron leads to changes in oxidative stress, endothelial function, and potential renal damage depending on the iron formulation (related to the generation of “free” or catalytic labile iron) and this may result in more tubular and glomerular injury manifested as increased proteinuria and raised neutrophil gelatinase–associated lipocalin (NGAL) levels in patients with chronic kidney disease (CKD). Methods IRON-CKD is a prospective, open-label, explorative, randomized, single-center study designed to compare the safety and efficacy of three parenteral iron preparations: low-molecular-weight iron dextran–Cosmofer, iron sucrose–Venofer, and iron isomaltoside–Monofer. The study includes 40 adults who have established CKD stages 3–5 and serum ferritin (SF) of less than 200 μg/L or transferrin saturation (TS) of less than 20% (or both); they were randomly assigned in a 1:1:1:1 ratio to 200 mg iron dextran, 200 mg iron sucrose, 200 mg iron isomaltoside, or 1000 mg iron isomaltoside. After randomization, participants undergo baseline assessments and then an iron infusion. Each participant is followed up at 2 h, day 1, week 1, and months 1 and 3. At each follow-up visit, patients undergo clinical review, measurement of pulse wave velocity (PWV), blood tests for renal function, and collection of serum/plasma samples for oxidative stress and inflammatory markers. The primary outcomes are measures of oxidative stress, inflammatory markers, and markers of acute renal injury in comparison with baseline measures of each iron preparation and between each of the iron preparations. Secondary objectives include effects on hematinic profiles and hemoglobin concentrations, changes in arterial stiffness, incidence of significant side effects, and change in patients’ quality of life. Results Between October 2015 and April 2018, 521 individuals were identified as potential participants; 216 were contacted, 56 expressed an interest, 49 attended a screening visit, and 40 were confirmed to meet the eligibility criteria and were randomly assigned. The mean age was 58.3 (standard error of the mean 4.4) years, and 23 (58%) were male. All patients were white and English-speaking. The mean SF was 66.6 μg/L, TS was 21.2%, and hemoglobin was 121.6 g/L at randomization for the whole group. The mean estimated glomerular filtration rate was 27.8 mL/min, the urinary protein/creatinine ratio was 104.3 mg/mmol, and CRP was 6.65 mg/L. Discussion IRON-CKD will provide important information on the short-term effects of three preparations of IV iron in CKD patients with biochemical functional or absolute iron deficiency on measures of oxidative stress, inflammation, endothelial function, and renal injury.
