The goal of this clinical trial is to learn if AP301 could work in the patients receiving maintenance dialysis with elevated blood phosphate. The main questions it aims to answer are: * Does AP301 lower blood phosphate levels? * Does AP301 works on serum calcium level, calcium times phosphate level, and intact parathyroid hormone level? * What discomfort or medical problem do the patients have when taking AP301? * Does AP301 improve quality of life in Chinese patients? The researchers will compare AP301 to an ineffective comparator (a look-alike substance that contains low dose AP301) to see if AP301 works to treat elevated blood phosphate. In the study, the patients will experience the following stages in a chronicle order: * Stop all using blood phosphate-lowering drugs, * Take AP301 or the comparator three times a day for 8 weeks, * Take AP301 three times a day for 24 weeks, and * Take AP301 or the comparator three times a day for 3 weeks. In the first 32 weeks, the dose of AP301 will be adjusted upwards or downwards based on the patient's blood phosphate level and the study doctor's judgment. If the participant has a blood phosphate level above or below a certain level, they may receive additional treatment to lower the blood phosphate level.

NCT05085275
A 9-month randomized, double-blind, placebo-controlled study to compare the effect of fixed dose ferric citrate versus placebo in patients with advanced chronic kidney disease (eGFR ≤20 ml/min/1.73m2) on the composite endpoint of time to initiation of maintenance dialysis or all-cause mortality.
NCT03573089
During end-stage kidney disease, clinical guidelines suggest reducing elevated phosphate levels in the blood. However, the effect of lowering blood phosphate levels on important patient-centred outcomes has never been tested. This trial will evaluate whether compared to high levels, lowering blood phosphate levels would reduce death or major events due to heart disease, improve physical health, and be cost-effective.
NCT05699239
A phase 2, randomized, placebo-controlled, double-blind, dose-finding study of TS-172 in hyperphosphatemia patients on hemodialysis
NCT04456803
To evaluate the efficacy and safety of ferric citrate tablet in the control of serum phosphorus levels in patients with chronic kidney disease undergoing hemodialysis.
NCT04579315
As Chronic Kidney Disease (CKD) progresses normophosphatemia is maintained by increasing the per nephron urinary phosphorus excretion. Clinically, hyperphosphatemia is associated with high mortality, vascular calcification, endothelial dysfunction and progression of left ventricular hypertrophy. Currently the treatment of hyperphosphatemia is first being initiated in stage 5 and consists of dietetic guidance to avoid dietary phosphate and treatment with oral phosphate binders. However, studies have shown important side effects to phosphate binders in terms of progression of vascular calcifications. Therefore, it might be beneficial to start the dietetic treatment with a reduction of dietary phosphate earlier in the disease stage. The aim of this project is to develop a New Nordic Renal Diet (NNRD) for CKD patients' stage 3-4 and to examine the long-term effects in a period of 26-weeks. NNRD has a high content of vegetable foods, less animal products and more local food items with a lesser content of phosphorus.

NCT04256369
Introduction: Various commercial premixed parenteral nutrition (PN) solutions have been introduced to clinical practice in 3-compartment large volume bags. Olimel N9E is the formulary premixed PN formula at King Faisal Specialist Hospital and Research Centre (KFSH \& RC). The commercial premixed PN was associated with a significant cost reduction compared to the compounded PN, with lower incidence of infectious complications, compared to the compounded PN formula. Electrolyte irregularities are commonly encountered with PN use. Patients who develop high serum potassium, magnesium or phosphate levels while receiving premixed PN are shifted to a compounded PN with lower electrolyte content. This study aims to describe the incidence of shifting of premixed PN to a compounded PN secondary to high serum electrolytes in surgical patients receiving commercial premixed PN. Methods: This is a prospective, cohort, study, to be conducted at KFSH \& RC, Riyadh. This study is proposed to commence after obtaining the approval of the Research Ethical Committee at KFSH \& RC. Patients enrolment will start after the approval at KFSH \& RC, by data collection phase, that might extend for a suspected 6-month until achieving the target sample size of 55 patients. The analysis phase will follow and elapse for 2 months. This is followed by 2 months to get the initial abstract. All patients will have their potassium, magnesium, calcium and phosphorus levels assessed daily in the morning for the first 7 days of PN initiation. After the first week of PN support, according to the routine laboratories, electrolytes will be assessed at a minimum of three times a week thereafter while on PN. There will be no extra laboratory work obtained for the study purpose. The incidence of shifting from premixed PN to compounded PN will be assessed and reported. A description of the characteristics of patients who develop high serum level of electrolytes will be undertaken using regression analysis.
NCT00557323
Patients enrolled in a previous study (SPD405-309), who were exposed to lanthanum carbonate (Fosrenol), were eligible to continue on any prescribed treatment for hyperphosphatemia, including lanthanum carbonate (Fosrenol), for an additional 5 years. Patients were being observed for any bone adverse events or other serious adverse events, as well as the collection of mortality data.
NCT01069692
This study will compare placebo to 4 different doses of SBR759 to assess the phosphate lowering efficacy in dialysis patients.
NCT00660530
Patients with end-stage renal disease (ESRD) commonly develop hyperphosphatemia due to the loss of excretory function of the kidney. This in turn may lead to the development of secondary hyperparathyroidism (SHPT) and renal osteodystrophy. Lanthanum carbonate, a phosphate binding agent, works by releasing lanthanum ions in the gastrointestinal tract to bind dietary phosphate and is effective in the management of hyperphosphatemia and in preventing secondary hyperparathyroidism. Patients taking lanthanum carbonate as part of their phosphate binder therapy are counseled to chew the tablets completely before swallowing, with or immediately after meals. However, ESRD patients who are intubated or are receiving enteral tube feedings are unable to chew the lanthanum carbonate tablets. For such patients, medications are commonly crushed and administered through a gastrostomy tube (G-tube). Some patients may also prefer to crush the lanthanum carbonate tablets and mix it with food instead of chewing. To date, it is not known if crushing the lanthanum carbonate tablets prior to administration and taking it with food will be as efficacious as chewing it. The objective of this study is to compare the efficacy of phosphate binding between chewed and crushed lanthanum carbonate in patients undergoing hemodialysis.

Randomized. double blind, placebo controlled, parallel arms dose finding study with a 4 weeks treatment period
NCT03146923
Based on new evidence renal dietitians in Ireland are revising the diet sheet that is used to teach patients about reducing blood phosphate. Changes that renal dietitians plan to make to the dietary phosphorus prescription * Inclusion of some nuts and pulses * More detailed education re phosphate additives * More accurate protein prescription * Inclusion of more whole grains * Encouraging the use of foods with a low phosphorus to protein ratio The investigators want to test the two diet prescription to find out, which one is better at reducing blood phosphate and which one is more acceptable to patients. The investigators also want to make sure it is safe.
NCT00458289
Patients with end-stage renal disease (ESRD) commonly have high concentrations of phosphorous, a mineral, in the blood (hyperphosphatemia). This is a result of their inability to excrete phosphorous by the kidneys. This in turn may result in the development of a condition known as secondary hyperparathyroidism and renal osteodystrophy or bone disease. As such, these patients often receive medications known as phosphate binders such as calcium carbonate or acetate, sevelamer, aluminum hydroxide and lanthanum carbonate to manage and treat hyperphosphatemia. Lanthanum carbonate is a newly available phosphate binding agent that is effective in the management of hyperphosphatemia and preventing secondary hyperparathyroidism. It works in the gastrointestinal tract by binding to the phosphorus in the diet. ESRD patients taking lanthanum carbonate are counseled to chew the tablets completely before swallowing, with or immediately after meals. However, patients who are intubated or receiving nutrition via feeding tubes are unable to chew the tablets. For these patients, medications are commonly crushed and administered via the tube. Moreover, some patients prefer to crush the tablets and mix it with food instead of chewing. To date, it is not known if crushing the lanthanum carbonate tablets prior to administration and taking it with food would be as effective as chewing them. The purpose of this study is to compare the efficacy of phosphate binding between chewed and crushed lanthanum carbonate tablets.
