Tenapanor for peritoneal dialysis patients with hyperphosphatemia: a phase 3 trial.

ABSTRACT:

Background

Tenapanor is a novel selective inhibitor of intestinal sodium/hydrogen exchanger 3 transporter. This is the first trial to assess the efficacy and safety of tenapanor in Japanese patients with hyperphosphatemia who are undergoing peritoneal dialysis.

Methods

This phase 3, open-label, multicenter, single-arm clinical trial targeted patients whose serum phosphorus was within 3.5-7.0 mg/dL with phosphate binders at screening. After phosphate binder washout, tenapanor was orally administered twice-daily, stepwise from 5 to 30 mg/dose for 16 weeks.
