WALTHAM, Mass., April 30, 2019 /PRNewswire/ -- Renal Research Institute (RRI), a division of Fresenius Medical Care North America (FMCNA), announced that its novel concept for "displacer-enhanced dialysis" has been selected as a winner of the KidneyX Redesign Dialysis competition. The proposal aims to develop a new displacer substance that can rid the blood of protein-bound uremic toxins that are notoriously difficult to remove by hemodialysis and negatively impact patient health.

"In the past decade there has been far too little progress in our ability to remove these toxins during hemodialysis," said Dr. Peter Kotanko, Research Director at RRI. "We are excited to be recognized for our research and this new effort to find a practical solution that would help improve the quality of life for patients requiring life-sustaining hemodialysis treatment."

The Kidney Innovation Accelerator (KidneyX) is a public-private partnership between the U.S. Department of Health and Human Services and the American Society of Nephrology to accelerate innovation in the prevention, diagnosis and treatment of kidney diseases. RRI is one of 15 winners for this first phase of the Redesign Dialysis competition.

"This competition is a new opportunity to advance innovations that will hopefully improve outcomes for all patients with renal disease," said Dr. Robert Kossmann, Chief Medical Officer at Fresenius Medical Care North America. "This award to the RRI team further demonstrates our ongoing commitment to turning research into practical solutions and new technologies."

As described in RRI's proposal, higher levels of protein-bound uremic toxins are associated with poorer outcomes in chronic kidney disease. These toxins are bound to a protein called albumin which is too large to be removed with conventional hemodialysis. Through "displacer-enhanced dialysis," a displacer substance is infused into the dialysis machine's blood tubing upstream of the artificial kidney, outside of the patient's body. This displacer binds to the same binding sites on albumin as the toxins, displaces them from the albumin molecule and allows them to be easily removed in the artificial kidney.

While laboratory experiments and a recent patient study published in the Clinical Journal of American Society of Nephrology confirmed this effect, current proof of concept displacers are not suitable for longer-term use. The goal of RRI's winning proposal is to advance the search for ideal displacer substances that can be used routinely in chronic hemodialysis and study the effects of longer-term use of those displacers.

In March, the FDA granted breakthrough device designation to FMCNA's computer-assisted ultrafiltration control software in development to improve fluid management during hemodialysis. The software will be designed to work with newer Fresenius Medical Care hemodialysis machines using the CLiC™ device.
