Ardelyx Announces Publication of Two Plain Language Summaries from XPHOZAH (tenapanor) Clinical Trials in Current Medical Research and Opinion

WALTHAM, Mass., July 31, 2024 (GLOBE NEWSWIRE) -- Ardelyx, Inc. (Nasdaq: ARDX), a biopharmaceutical company founded with a mission to discover, develop and commercialize innovative, first-in-class medicines that meet significant unmet medical needs, today announced the publication of plain language summaries of results from two clinical trials on XPHOZAH (tenapanor), NORMALIZE and OPTIMIZE, in Current Medical Research and Opinion. The plain language summaries were developed by the authors to help adult patients with chronic kidney disease receiving dialysis, and their family members and caregivers, better understand some of the safety and efficacy data related to XPHOZAH.

XPHOZAH, the first and only phosphate absorption inhibitor (PAI), is approved by the U.S. Food and Drug Administration to reduce serum phosphorus in adults with chronic kidney disease (CKD) on dialysis as add-on therapy in patients who have an inadequate response to phosphate binders or who are intolerant of any dose of phosphate binder therapy. XPHOZAH offers a different mechanism of action, blocking phosphate absorption at the primary pathway and is administered as a single tablet taken twice daily.

“We are proud to provide the clinical trials results for both the NORMALIZE and OPTIMIZE studies to patients in a format that is both useful and relevant to their needs. Plain language summaries, like these, help patients and their caregivers better understand their options and the potential impact XPHOZAH may have on lowering their serum phosphorus levels,” said Laura Williams, MD MPH, chief medical officer of Ardelyx. “Our entire Ardelyx team would like to express our gratitude to the patients who participated in these clinical trials, whose contributions are now helping other patients better understand the complications associated with elevated serum phosphorus and this new treatment option. We would also like to recognize the study authors who worked with our partners in the patient advocacy community to ensure that these plain language summaries could be made available to our patients.”

Current Medical Research and Opinion is an international journal that publishes research focused on new and existing drugs and therapies, best practices in patient care, developments in diagnostic medicine and medical technology, and innovations in medical and scientific publishing. The first article, titled “Tenapanor improves long-term control of high phosphate concentrations in the blood in patients receiving maintenance dialysis: a plain language summary of the NORMALIZE study,” describes results from the NORMALIZE study, is available online and can be found here. The second article, titled “Effectiveness of tenapanor for treating hyperphosphatemia in patients receiving dialysis: a plain language summary of the OPTIMIZE study” provides a review of the OPTIMIZE study, is available online and can be found here. Both articles are summaries of data originally published in Kidney360.
