BLOCK PHOSPHATE


With XPHOZAH as add-on therapy for patients on dialysis in whom a phosphate binder does not work well1

How many of your patients on a phosphate binder have serum phosphorus levels above target?

A different approach is here

A non-binder mechanism of action

Blocks the primary pathway of phosphate absorption1

XPHOZAH works via local inhibition of the sodium/hydrogen exchanger 3 (NHE3) in the gastrointestinal (GI) tract to specifically block paracellular phosphate absorption.1

Driving to efficacy

Reduces serum phosphorus1-4

XPHOZAH met the key efficacy endpoints in three phase 3 trials: two monotherapy trials and one trial as add-on therapy with a phosphate binder.

Driving to safety

Established safety and tolerability profile1

Across three phase 3 clinical trials in 754 XPHOZAH-treated patients with hyperphosphatemia.

Indication

XPHOZAH (tenapanor) 30 mg BID is 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.

Important Safety Information

Contraindications

XPHOZAH is contraindicated in:

  • Pediatric patients under 6 years of age
  • Patients with known or suspected mechanical gastrointestinal obstruction

Warnings and precautions

Diarrhea

Patients may experience severe diarrhea. Treatment with XPHOZAH should be discontinued in patients who develop severe diarrhea.

Most Common Adverse Reactions

Diarrhea, which occurred in 43-53% of patients, was the only adverse reaction reported in at least 5% of XPHOZAH-treated patients with CKD on dialysis across trials. The majority of diarrhea events in XPHOZAH-treated patients were reported to be mild-to-moderate in severity and resolved over time, or with dose reduction. Diarrhea was typically reported soon after initiation but could occur at any time during treatment with XPHOZAH. Severe diarrhea was reported in 5% of XPHOZAH-treated patients in these trials.
