Brief Summary:
The study is designed to evaluate the ability of tenapanor alone or in combination with sevelamer to achieve serum phosphorus concentration (sP) within the population reference range (sP \>2.5 and ≤4.5 mg/dL) in patients with end-stage renal disease (ESRD) on dialysis with hyperphosphatemia (\>4.5 mg/dL).
Detailed Description:
Patients who complete the TEN-02-301 study (PHREEDOM) may be eligible to enroll into TEN-02-401 (NORMALIZE).
Patients from the TEN-02-301 tenapanor arm will either receive only tenapanor or be given sevelamer in addition to tenapanor based on their sP. Patients from the TEN-02-301 sevelamer arm will be given tenapanor in addition to their sevelamer dose and the sevelamer dose will then be adjusted based on their sP following a protocol-specified dose titration schedule. Patients will be monitored for safety and efficacy with in-office and telephone visits for up to an additional 18 months.
Laboratory assessments will be measured at every visit (Weeks 1, 2, 3, 4, 6 and 8 and Months 3, 6, 9, 12, 15 and 18) using a central laboratory.
Safety assessments will be performed during the study and will include physical examinations, vital signs (blood pressure and pulse), body weights, clinical laboratory evaluations, 12-lead electrocardiograms (ECGs), and adverse event (AE) monitoring.
