Clinical Trial Summary

This Phase 3, 26-week, open label study with a 12-week, placebo-controlled, randomized withdrawal period followed by an open label long term safety extension will evaluate the safety and efficacy of tenapanor to treat hyperphosphatemia in end-stage renal disease (ESRD) on hemodialysis and peritoneal dialysis.


Clinical Trial Description

The study consists of a screening visit, a phosphate binder-free washout period of up to 4 weeks, a 26-week treatment period, an up to 12-week placebo-controlled, randomized withdrawal period, during which patients are randomized 1:1 to either remain on their tenapanor treatment or placebo, followed by an open label safety extension period for a total treatment period of up to 52 weeks. An active control group, for safety analysis only, will receive sevelamer carbonate, open label, for the entire 52-week study period Depending on increase in serum phosphate (s-P) levels, subjects can be randomized 2 or 3 weeks after being taken off their phosphate lowering medication. Subjects who qualify to enroll in the study will be randomized 3:1 to either receive tenapanor at a dose of 30 mg bid or sevelamer carbonate. ;
