Active clinical trials for "Hyperphosphatemia"

Primary Objective: To demonstrate efficacy of Renvela tablets in the reduction of serum phosphorus in hyperphosphatemia in participants with chronic kidney disease not on dialysis. Secondary Objectives: To document the efficacy of Renvela tablets in the reduction of serum lipids (total cholesterol and low-density lipoprotein cholesterol [LDL-C]). To document the efficacy of Renvela tablets in the reduction of calcium-phosphorus product. To document the efficacy of Renvela tablets in the reduction of intact parathyroid hormone (iPTH). To document the efficacy of Renvela tablets in proportion of participants reaching the target serum phosphorus level 4.6 milligrams per decilitre (mg/dL) (1.47 millimoles per litre [mmol/L], inclusive). To evaluate safety of Renvela tablets.

The purpose of this randomized clinical trial is to evaluate alternative technology-supported behavioral approaches to engaging 42 maintenance hemodialysis (HD) patients with persistent hyperphosphatemia in phosphorus binder adherence and dietary phosphorus restriction. Participants will be randomized to 1 of 3 intervention groups: (1) Education (Edu); (2) Edu + Self-Monitoring (SM); or (3) Edu + SM + Social Cognitive Theory (SCT)-based training program.

This study is a randomized study designed as a 2x2 cross-over in two periods (Period 1 and Period 2) to assess the safety, pharmacokinetics (PK), pharmacodynamics (PD), and efficacy of EOS789 in patients with chronic kidney disease (CKD) and hyperphosphatemia receiving hemodialysis. Period 1 is double-blind and Period 2 is open-label. Period 1 and Period 2 are identical with regard to the design, inclusion/exclusion criteria, and assessments. EOS789 and its combination with sevelamer carbonate are tested in Period 1 and Period 2 respectively.

This study will compare placebo to 4 different doses of SBR759 to assess the phosphate lowering efficacy in dialysis patients.

Cardiovascular disease is a major cause of death in hemodialysis (HD) patients and is associated with widespread vascular calcification. There is a consensus that the chronic overload of calcium and phosphorus is a major factor in vascular calcification. Hyperphosphatemia, deleterious in dialysis patients, is aggressively monitored and treated. Phosphate binders - designed to bind dietary phosphate and thus prevent its absorption, are ubiquitous in the dialysis patient population, and calcium-based phosphate binders are often first line therapy because they are tolerated well by the patients and low in cost. Phosphate Kinetic Modeling (PKM) is a tool to help physicians manage a hemodialysis patient's phosphate level. Once a subject consents to participate in the study, the subject's dietary phosphate intake will be estimated and the appropriate dose of the phosphate binder calcium acetate (PhosLo) will be recommended accordingly. If necessary, the Ca++ concentration of the dialysate will be changed to remove any excess calcium absorbed as the result of an increase in the PhosLo prescription to control phosphorus.Ongoing recommendations regarding oral phosphate binders dialysate calcium will be made using a computer generated algorithm.

This study will evaluate the efficacy of SBR759 compared to sevelamer HCl in lowering serum phosphate levels in Chronic Kidney Disease patients on hemodialysis

A long-term study of BAY77-1931 (lanthanum carbonate) for hyperphosphatemia in patients undergoing hemodialysis

The primary objectives of this study are the following: To demonstrate that AMG 223 will produce a statistically significant reduction in serum phosphorus compared with placebo over a 3 week treatment period in subjects with CKD receiving dialysis To describe a dose response for AMG 223 To evaluate the safety and tolerability of AMG 223

This is a phase III multi-centre study in three periods: the first period is a phosphate binder washout for 4 weeks, the second period is an open-label, randomised, parallel group, flexible dose, the third period is a placebo-controlled withdrawal comparing MCI-196 with placebo for 4 weeks.

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.
