Study Endpoints

Primary Endpoints

Change From Baseline in Serum Phosphorus at Week 8
Baseline, Week 8

Baseline of serum phosphorus value was the last serum phosphorus level obtained before the first double-blind investigational medicinal product (IMP) dosing. Missing Week 8 data were imputed by last observation carried forward \[LOCF\] method.

The reduction in serum phosphorus from baseline to end of study with Sevelamer carbonate tablets 800 mg and Sevelamer carbonate Powder 2.4 g in chronic kidney disease (CKD) patients both on haemodialysis and not on dialysis
up to 8 weeks
Demonstrate the efficacy of sevelamer carbonate powder dosed QD with the largest meal to sevelamer hydrochloride tablets dosed TID with meals on the control of serum phosphorus
Up to 24 weeks
Evaluate the safety and tolerability of sevelamer carbonate powder dosed QD with the largest meal compared to sevelamer hydrochloride tablets dosed TID with meals
Up to 24 weeks
Change From Baseline (Week 0) to Week 2 in Serum Phosphorus
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.

Treatment - Emergent Adverse Events (AEs)
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.

Frequently asked questions about Sevelamer carbonate

What is Sevelamer carbonate used for?

Sevelamer carbonate is used for hyperphosphatemia, or elevated blood phosphate, in patients with chronic kidney disease, including those with renal failure and those on hemodialysis. It is a small molecule being developed by Sanofi and is currently in Phase 3 clinical development for these kidney-related conditions.

What does Sevelamer carbonate target?

Sevelamer carbonate is a phosphate binder. It works by binding to phosphate in the gastrointestinal tract, reducing its absorption and lowering blood phosphate levels in patients with chronic kidney disease and hyperphosphatemia. This mechanism helps manage the complications of elevated phosphate in these patients.

Who makes Sevelamer carbonate?

Sevelamer carbonate is being developed by Sanofi, a global biopharmaceutical company listed on the stock exchange under the ticker symbol SNY. Sanofi is conducting clinical trials to evaluate the drug for the treatment of hyperphosphatemia in patients with chronic kidney disease.

What phase is Sevelamer carbonate in?

Sevelamer carbonate is in Phase 3 clinical development for chronic kidney disease and hyperphosphatemia. It is an investigational drug and has not been approved by regulatory authorities. Several Phase 3 trials have been completed, but the drug remains under investigation for these indications.

What clinical trials is Sevelamer carbonate in?

Sevelamer carbonate has been studied in several completed clinical trials, including NCT00681941, a Phase 3 open-label dose titration study in hyperphosphatemic CKD patients not on dialysis, and NCT01736150, a Phase 3 dose-titration study in CKD patients on hemodialysis. Both trials enrolled adult patients.

Is Sevelamer carbonate the same as sevelamer hydrochloride?

Sevelamer carbonate is a different salt form of sevelamer compared to sevelamer hydrochloride. A clinical trial, NCT00440648, was conducted as a cross-over study comparing sevelamer hydrochloride and sevelamer carbonate in patients with chronic kidney disease, indicating they are distinct formulations of the same active moiety.
