Abstract
Hyperphosphatemia is an electrolyte disorder highly prevalent in patients with chronic kidney disease undergoing hemodialysis (HD) that usually requires treatment with oral phosphate binders (PBs). Sucroferric oxyhydroxide (SO) is a calcium-free, iron-based PB indicated for the control of serum phosphorus. In the real-world setting, SO has shown clinical effectiveness with a lower pill burden and has also been associated with reduced hospital admission rates. This study aims to assess the potential economic benefits resulting from the introduction of SO to the health-care setting of the Kingdom of Saudi Arabia (KSA). An economic analysis using data from a retrospective real-world study that compared HD patients with uninterrupted SO prescriptions with patients who discontinued SO and switched to other PBs (oPBs). Annual drug costs for the estimated PB-eligible population in KSA were quantified. Costs per responder were estimated for all treatments. Hospital admissions' incidence rates were converted into annual inpatient cost savings and were deducted from drug costs to estimate the annual economic effect of SO versus oPBs. Sensitivity and breakeven analyses were also conducted. The eligible population for PB therapy in KSA was estimated at n = 14,748. Treating therapy-eligible populations exclusively with SO was estimated to generate annual inpatient cost-savings of SAR 107.4-119.4 million compared to treating the population with oPBs. The estimated economic effect signified overall annual savings ranging from SAR 82.8 to SAR 94.8 million when the population is treated with SO. Sensitivity analyses showed persistent cost savings. The estimated benefit-cost ratios showed that for every SAR 1 spent on SO, the expected return on investment was SAR 4.4-4.9. SO is an effective therapy that may result in substantial cost savings from reducing hospital admission costs that are attributable to hyperphosphatemia among HD patients.

Abstract
BACKGROUND Uncontrolled hyperphosphatemia in chronic kidney disease (CKD) patients commonly results in vascular calcification leading to increased risk of cardiovascular disease. Phosphate binders (PBs) are used for hyperphosphatemia and can be calcium-based (CBPBs) or non-calcium-based (NCBPBs), the latter being more expensive than CBPBs. In this study, we used meta-analysis approaches to assess the cost-utility of PBs for hyperphosphatemia in CKD patients. METHODS Relevant studies published prior to June 2019 were identified from PubMed, Scopus, the Cochrane Library, the National Health Service Economic Evaluation Database, and the Cost-Effectiveness Analysis Registry. Studies were eligible if they included CKD patients with hyperphosphatemia, compared any PBs and reported economic outcomes. Meta-analysis was applied to pool incremental net benefit (INB) across studies stratified by country income. RESULTS A total of 25 studies encompassing 32 comparisons were eligible. Lanthanum carbonate, a NCBPB, was a more cost-effective option than CBPBs in high-income countries (HICs), with a pooled INB of $3984.4 (599.5-7369.4), especially in pre-dialysis patients and used as a second-line option with INBs of $4860.2 (641.5-9078.8), $4011.0 (533.7-7488.3), respectively. Sevelamer, also a NCBPB, was not more cost-effective as a first-line option compared to CBPBs with a pooled INB of $6045.8 (- 23,453.0 to 35,522.6) and $34,168.9 (- 638.0 to 68,975.7) in HICs and upper middle-income countries, respectively. CONCLUSIONS Lanthanum carbonate was significantly more cost-effective than CBPBs as a second-line option for hyperphosphatemia in pre-dialysis patients in HICs. However, the use of sevelamer is not more cost-effective as a first-line option compared to CBPBs.

Abstract
UNLABELLED Alterations in bone and mineral metabolism are very common in chronic kidney disease (CKD). The increase in phosphate levels leads to bone disease, risk of calcification and greater mortality, so any strategy aimed at reducing them should be welcomed. The latest drug incorporated into the therapeutic arsenal to treat hyperphosphataemia in CKD is Sucroferric Oxyhydroxide (SFO). OBJECTIVE To analyse the efficacy and safety of OSF in three cohorts of patients, one with advanced chronic kidney disease not on dialysis (CKD-NoD), another on peritoneal dialysis (PD) and the last on haemodialysis (HD), followed for six months. METHODS A prospective, observational, multicentre study in clinical practice. Clinical and epidemiological variables were analysed. The evolution of parameters relating to alterations in bone and mineral metabolism and anaemia was analysed. RESULTS Eighty-five patients were included in the study (62 ± 12 years, 64% male, 34% diabetic), 25 with CKD-NoD, 25 on PD and lastly, 35 on HD. In 66 patients (78%), SFO was the first phosphate binder; in the other 19, SFO replaced a previous phosphate binder due to poor tolerance or efficacy. The initial dose of SFO was 964 ± 323 mg/day. Overall, serum phosphate levels saw a significant reduction at three months of treatment (19.6%, P < 0.001). There were no differences in the efficacy of the drug when the different populations analysed were compared. Over the course of the study, there were no changes to levels of calcium, PTHi, ferritin, or the transferrin and haemoglobin saturation indices, although there was a tendency for the last two to increase. Twelve patients (14%) withdrew from follow-up, ten due to gastrointestinal adverse effects (primarily diarrhoea) and two were lost to follow-up (kidney transplant). The mean dose of the drug that the patients received increased over time, up to 1147 ± 371 mg/day. CONCLUSIONS SFO is an effective option for the treatment of hyperphosphataemia in patients with CKD both in the advanced phases of the disease and on dialysis. We found similar efficacy across the three groups analysed. The higher their baseline phosphate level, the greater the reduction in the serum levels. A notable reduction in phosphate levels can be achieved with doses of around 1000 mg/day. Diarrhoea was the most common side effect, although it generally was not significant.

Abstract
AIMS Hyperphosphatemia is common among patients with advanced chronic kidney disease (CKD) undergoing dialysis. The iron-based phosphate binder (PB), sucroferric oxyhydroxide (SO), has a low daily pill burden and is indicated for the control of serum phosphorus in these patients. In a retrospective database study, hemodialysis patients switched to long-term SO therapy had fewer hospitalizations compared with patients switched to other PB therapies. This economic analysis aimed to quantify potential cost-savings of reduced hospitalizations associated with SO for healthcare systems in five European countries. MATERIALS AND METHODS All-cause hospital admissions incidence data were sourced from a real-world retrospective database study comparing adult, in-center hemodialysis patients maintained on 2 years of SO therapy (mSO) versus patients who discontinued SO (dSO) within 90 days of their first prescription and switched to other PBs. A literature search was conducted to determine the cost per hospital admission for dialysis patients in the healthcare setting of each European country. A cost-model combined the incidence rate of all-cause hospital admissions and the cost per admission to estimate the country-specific inpatient costs for the mSO and dSO groups. RESULTS Annual inpatient cost-savings per patient in the mSO group versus the dSO group were €1,201, €2,097, €2,059, €1,512, and €3,068 in France, Germany, Italy, Spain, and the UK, respectively. When annual PB drug costs per patient were considered, the net annual economic cost-savings per patient were €327, €1,585, €1,022, €1,100, and €2,204, respectively. LIMITATIONS Hospital admissions data used in the analysis were observational in nature and derived from a US hemodialysis patient population; the effect of SO therapy on hospitalization rates for US and European hemodialysis patients may differ. The analysis did not consider indirect healthcare costs associated with hospitalizations. CONCLUSION SO therapy may offer substantial inpatient cost-savings by reducing all-cause hospital admissions attributable to uncontrolled hyperphosphatemia.

Abstract
INTRODUCTION Despite a better management of hyperphosphatemia in haemodialysis patients observed during the past years, most of them remain insufficiently treated and exposed to bone and cardiovascular complications that are associated with this biological abnormality. The availability of calcium-free phosphate binders among therapeutical options is confirmed to significantly reduce serum phosphate levels without the risk of excess exposure to calcium. Currently sucroferric oxyhydroxyde (SO) is the only iron-based phosphate binder available in France. METHODS A cohort of patients prescribed OHS has been extracted from the EUCLID 5 database between June 2016 and December 2017. The effects on bone mineral metabolism and ferritin have been retrospectively studied. RESULTS Two hundred and sixty-two patients with OHS prescription have been identified. The OHS treatment duration median was 4.3 months (1.84-10.99). The average midweek phosphatemia decreased significantly after OHS prescription (from 1.99 to 1.83 mmol/L ; P<0.0001) with a significant increase of the proportion of patients (12.1 to 25.7% ; P<0.0001) reaching the phosphate target of 1.5 mmol/L, without significant change in calcemia and PTH. Ferritinemia significantly increased from 362 to 427 μg/L in 3 months (P=0.0049). OHS therapy has been stopped and replaced in 18% of the cases. DISCUSSION Among the NephroCare cohort, OHS therapy was efficient to decrease phosphatemia and to increase significantly the proportion of patients in target. There were no short term changes in calcemia and PTH. The slight increase in ferritin confirms the findings of the phase III study and its extension. The effects on the pills count and the OHS side-effects are analyzed from literature. The risk of iron overload and the impact on the anemia management including EPO sparing are currently under study. CONCLUSION OHS therapy appears to be a new efficient alternative to non-calcium phosphate binders. A better knowledge of its side effects will help the patients and the physician to optimize the phosphate balance management. The slight increase in ferritin can be considered as an epiphenomenon because of the important iron needs and frequent check of this parameter in the anemia management.

Abstract
INTRODUCTION Etelcalcetide is a novel intravenous calcimimetic for the treatment of secondary hyperparathyroidism (SHPT) in haemodialysis patients. The clinical efficacy and safety of etelcalcetide (in addition to phosphate binders and vitamin D and/or analogues [PB/VD]) was evaluated in three phase III studies, including two placebo-controlled trials and a head-to-head study versus the oral calcimimetic cinacalcet. OBJECTIVE The objective of this study was to develop a decision-analytic model for economic evaluation of etelcalcetide compared with cinacalcet. METHODS We developed a life-time Markov model including potential treatment effects on mortality, cardiovascular events, fractures, and subjects' persistence. Long-term efficacy of etelcalcetide was extrapolated from the reduction in parathyroid hormone (PTH) in the phase III trials and the available data from the outcomes study in cinacalcet (EVOLVE trial). Etelcalcetide was compared with cinacalcet, both in addition to PB/VD. We applied unit costs averaged from five European countries and a range of potential etelcalcetide pricing options assuming parity price to weekly use of cinacalcet and varying it by a 15 or 30% increase. RESULTS Compared with cinacalcet, the incremental cost-effectiveness ratio of etelcalcetide was €1,355 per QALY, €24,521 per QALY, and €47,687 per QALY for the three prices explored. The results were robust across the probabilistic and deterministic sensitivity analyses. CONCLUSIONS Our modelling approach enabled cost-utility assessment of the novel therapy for SHPT based on the observed and extrapolated data. This model can be used for local adaptations in the context of reimbursement assessment.
