This is a research study for people with high blood phosphorus levels who are on dialysis. This medical condition can cause weakening of the bones and damage other organs. This can lead to many health problems, and sometimes death. Phosphorus is in much of the food we eat, and is helpful to us in small amounts. Patients with kidney failure have trouble getting rid of the phosphorus eaten in food. Dialysis can help remove some of the phosphorus, but often patients must take a phosphate binder like PhosLo®, Renagel®, or Renvela® to bring the blood phosphorus levels back to normal. The purpose of this study is to see if KRX-0502 (ferric citrate) is safe and effective as a phosphate binder.
There will be a screening visit about 4 weeks receiving study drug. Upon qualifying for the study after the screening visit, patients will then be asked to stop taking their current phosphate binder for about 2 weeks. Then, if patients continue to qualify for the study, they will be entered in the study that lasts about 28 days. Study visits will happen every week during the patient's usual dialysis appointments. There will be a total of up to 9 visits for this study, and total participation time could last up to 8 weeks.
Allocation: Randomized, Control: Dose Comparison, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Transition to Ferric Citrate among Hemodialysis and Peritoneal Dialysis Patients: A Phase 4 "Real World" Experience Study from Kaiser Permanente Southern California
The purpose of this study is to evaluate the safety and tolerability of Zerenex™ (ferric citrate) as a treatment for hyperphosphatemia in patients with End-Stage Renal Disease. These pat...
The risk of cardiovascular mortality in patients with end stage renal disease on hemodialysis is 10-100 times higher than the normal population. This is due in part to high levels of infla...
The main objective of the study is to compare the impact of oral ferric citrate compared to standard of care oral ferrous sulfate on serum iron, percent transferrin saturation, ferritin, h...
To assess the long-term safety and effectiveness of Nephoxil® for the treatment of hyperphosphatemia in patients with ESRD undergoing dialysis.
Ferric hydroxide precipitation and flocculation is the most commonly used method for the removal of arsenic in water treatment. However, citrate often interrupts the precipitation of ferric hydroxides...
Serum phosphate and vitamin D receptor activator regulate fibroblast growth factor 23 (FGF23), and iron may modulate FGF23 metabolism. The aim of the present study was to elucidate the effects of ferr...
Amyloid beta (Aβ) aggregation and oxidative stress are two of the central events in Alzheimer's Disease (AD). Both these phenomena can be caused by the interaction of Aβ with metal ions. In the last...
Blood contains a poorly characterized pool of labile iron called non-transferrin-bound iron (NTBI). In patients with iron-overload diseases such as hemochromatosis, NTBI accumulates in the liver, hear...
Regional citrate anticoagulation has been associated with enhanced biocompatibility in hemodialysis, but the optimal dose of citrate remains to be established. Here, we compared parameters related to ...
A species of gram-positive, aerobic bacteria that causes granulomatous or ulcerating skin lesions in immunosuppressed persons. This organism owes its name to its requirement for growth of high levels of iron, conveniently supplied as blood, heme, or ferric ammonium citrate.
The reaction of potassium ferrocyanide with ferric iron to yield a dark blue precipitate at the sites of the ferric iron. Used to determine ferric iron in tissues, particularly in the diagnosis of disorders of iron metabolism.
An enzyme that, in the presence of ATP and COENZYME A, catalyzes the cleavage of citrate to yield acetyl CoA, oxaloacetate, ADP, and ORTHOPHOSPHATE. This reaction represents an important step in fatty acid biosynthesis. This enzyme was formerly listed as EC 22.214.171.124.
Enzyme that catalyzes the first step of the tricarboxylic acid cycle (CITRIC ACID CYCLE). It catalyzes the reaction of oxaloacetate and acetyl CoA to form citrate and coenzyme A. This enzyme was formerly listed as EC 126.96.36.199.
A polymeric amine that binds phosphate and is used to treat HYPERPHOSPHATEMIA in patients with kidney disease.
In medicine, dialysis is a process for removing waste and excess water from the blood, and is primarily used to provide an artificial replacement for lost kidney function in people with renal failure. Dialysis may be used for those with an acute disturba...
Arthroplasty Joint Disorders Orthopedics Spinal Cord Disorders Orthopedics is the science or practice of correcting deformities caused by disease or damage to the bones and joints of the skeleton. This specialized branch of surgery may ...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
