Clinical Validation Study for Optimization of Anemia MAnagement in Hemodialysis Patients With End Stage Kidney Disease Using the Dialysis Anemia TReatmenT Model
- Conditions
- Dialysis
- Interventions
- Procedure: Standard of careProcedure: Algorithm model-based Aranesp doses
- Registration Number
- NCT05936021
- Lead Sponsor
- Intermountain Health Care, Inc.
- Brief Summary
This is a human subject research study conducted in patients undergoing dialysis treatment with darbepoetin alfa at Intermountain Utah Dialysis and Intermountain Medical Center Dialysis Services. The purpose is to test a dose recommendation algorithm that may reduce hemoglobin variability and drug cost.
- Detailed Description
Hemoglobin cycling is an outcome of treating long-term dialysis patients for anemia using erythropoiesis-stimulating agents (ESAs), and represents a conundrum for practitioners. While patients with low hemoglobin levels suffer from anemia, high hemoglobin levels may lead to blood clots and subsequent health risks. The current protocol for ESA dosing often results in suboptimal dosing that leads to hemoglobin cycling, which can have a negative impact on patient survival. To this end, we have developed a personalized method for ESA dosing that controls anemia in dialysis patients that is similar to the commercial product sold by PhySoft. Our method, the Dialysis Anemia Treatment Model, uses a mathematical model for erythropoiesis that takes each patient's physiology into account, predicting the optimal dose of ESA for that patient to prevent hemoglobin cycling. The goal of this computer-aided approach is to reduce hemoglobin cycling and the amount of drug used by predicting optimal doses to keep the patient's hemoglobin within the desired range. This is a human subject research study to validate the model in the clinic and demonstrate that it is able to minimize hemoglobin cycling in patients and reduce the amount of ESA drug administered.

Group Intervention Description Standard of care Standard of care All patients placed on dialysis receive standard of care Model-based Aranesp doses Algorithm model-based Aranesp doses On entering the study cohort, patients will begin receiving doses calculated by the algorithm instead of by the standard of care procedures. Model-based Aranesp doses will be computed at the same time that doses based on the dialysis anemia protocol are determined. The model-based doses will be administered instead of the protocol-based doses and in the same way and at the same time as the protocol-based doses would have been.
