Brief Summary:

Objective: In hyperphosphatemic pediatric participants with chronic kidney disease (CKD) to

  • Evaluate the safety and tolerability of sevelamer carbonate
  • Evaluate the efficacy of sevelamer carbonate on the control of serum phosphorus

Condition or disease Intervention/treatment Phase
Hyperphosphatemia Chronic Kidney Disease Drug: Placebo Drug: Sevelamer carbonate Phase 2

Detailed Description:
The study was divided into 3 periods: a phosphate binder washout Period; a randomized, double-blind, placebo-controlled, Fixed Dose Period; and an open-label, sevelamer carbonate Dose Titration Period.

Arm Intervention/treatment
Placebo Comparator: FDP-Placebo for Sevelamer Carbonate, DTP-Sevelamer Carbonate
Participants received placebo for 2 weeks during the fixed dose period (FDP). Participants received sevelamer carbonate for 26 weeks in dose titration period (DTP).
Drug: Placebo
Placebo for 0.8 g sachets of powder for oral suspension or 800 mg tablets

Drug: Sevelamer carbonate
0.8 g sachets of powder for oral suspension or 800 mg tablets
Other Name: Renvela®

Experimental: FDP-Sevelamer Carbonate, DTP-Sevelamer Carbonate
Participants received sevelamer carbonate for 2 weeks during the FDP of the study. Participants received sevelamer carbonate for an additional 26 weeks in DTP.
Drug: Placebo
Placebo for 0.8 g sachets of powder for oral suspension or 800 mg tablets

Drug: Sevelamer carbonate
0.8 g sachets of powder for oral suspension or 800 mg tablets
Other Name: Renvela®




Primary Outcome Measures :
  1. Change From Baseline (Week 0) to Week 2 in Serum Phosphorus [ Time Frame: Baseline, Week 2 ]
    Full analysis set for fixed dose period (FAS-FDP) participants were analyzed according to their randomized treatment. The change in serum phosphorus (mg/dL) from baseline to week 2 was calculated.

  2. Treatment - Emergent Adverse Events (AEs) [ Time Frame: Up to 32 weeks (up to 4 weeks washout period, 2 weeks FDP and 26 weeks DTP) ]
    A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly/birth defect. AEs from the time of signing the informed consent through the end of the study for all participants. SAEs occurring during the 15 days following study completion or early termination were also to be collected.


Secondary Outcome Measures :
  1. Change From Baseline (Week 0) to Week 28/Early Termination in Serum Phosphorus [ Time Frame: Baseline, Week 28/Early Termination ]
    Full analysis set for dose titration period (FAS-DTP) participants were analyzed according to their randomized treatment. The change in serum phosphorus (mg/dL) from baseline to Week 28/Early Termination was calculated.
