Ardelyx Sets Specialty Pharmacy Limited Distribution Network for XPHOZAH®

Ardelyx, Inc., a biopharmaceutical company founded with a mission to discover, develop and commercialize innovative, first-in-class medicines that meet significant unmet medical needs, announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to XPHOZAH® (tenapanor) for the treatment of pediatric hyperphosphatemia.

Previously, Ardelyx announced that the  FDA approved XPHOZAH® (tenapanor), the first and only phosphate absorption inhibitor, indicated 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 is a single tablet taken twice daily that offers a first-in-class mechanism of action that blocks phosphate absorption through its primary pathway. Ardelyx has identified 550,000+ patients with CKD on dialysis in U.S., 80% of which require Rx treatment for hyperphosphatemia.

Ardelyx has selected 11 specialty pharmacies as limited distribution partners for XPHOZAH. National partners include:
