Ferric Citrate in ESRD Pilot Project

Running, not enrolling · Phase 4

Conditions studied: End Stage Renal Disease, Chronic Kidney Diseases

In brief

This research study is for participants that have End Stage Renal Disease (ESRD). ESRD is the last stage of chronic kidney disease. Anemia is very common in ESRD patients and require erythropoiesis-stimulating agents (ESAs) for treatment. Anemia happens when there are not enough red blood cells in your body. ESAs work by helping the bone marrow to produce red blood cells. There are two ESAs licensed for the treatment of anemia of Chronic Kidney Disease (CKD) in the Unites States: epoetin alfa and darbopoetin alfa. ESA therapy is considered safe. However, major adverse effects should be acknowledged, including an increased risk of death, thromboembolic complications, stroke, heart attack, aplastic anemia, tumor progression, and others. To minimize risks of these adverse events, careful monitoring of hemoglobin levels, along with adjustment of ESA dosing, to maintain the lowest hemoglobin level clinically needed is recommended. Ferric Citrate, also called Auryxia, is an iron-based phosphate binder that may decrease ESA usage while maintaining hemoglobin levels. Phosphate binders are medications used to reduce the body's absorption of phosphate. In a prior study, it was seen that some laboratory values, such as iron levels, changed positively in response to Auryxia. In this study we want to see if using Auryxia will cause a change in laboratory values and lower the use of ESAs in ESRD patients.
