National Kidney Foundation and Ardelyx, Inc. Survey Finds Dialysis Patients Struggle to Maintain Serum Phosphorus Levels

Majority of survey respondents call for new treatments to help manage phosphorus levels

WALTHAM, Mass. and NEW YORK, Nov. 4, 2022 /PRNewswire/ -- Ardelyx, Inc. (Nasdaq: ARDX) in partnership with the National Kidney Foundation (NKF), today announced results from a survey of patients with chronic kidney disease (CKD) on dialysis conducted to better understand patients' experience managing serum phosphorus levels. The survey found that more than 80% of respondents struggle to manage their serum phosphorus levels, with more than 90% citing a need for new treatment options.

"Despite best efforts with current treatment strategies, a significant proportion of patients have persistent hyperphosphatemia, placing them at an increased risk for mineral and bone disorder complications, including vascular disease," said Joseph Vassalotti, MD, chief medical officer for the National Kidney Foundation. "These survey results point to the difficulty people living with kidney diseases treated with dialysis have coping with low phosphorus diet and current medication schedules."

"We are proud to bring the patient voice to this important conversation," said Laura A. Williams, MD, chief medical officer of Ardelyx. "The idea for this survey, born from the Ardelyx Patient Advisory Council, provides great insight into the challenges patients face managing hyperphosphatemia and supports the need for innovation in this space. As a company committed to putting patients first, and as a CKD patient myself, we are proud of this collaborative effort that truly captures the voice of patients with kidney disease on dialysis."
