Renvela (Sevelamer Carbonate) - Summary



The active ingredient in Renvela is sevelamer carbonate, a polymeric amine that binds phosphate and is meant for oral administration. It was developed as a pharmaceutical alternative to sevelamer hydrochloride (Renagel). Sevelamer carbonate is an anion exchange resin, with the same polymeric structure as sevelamer hydrochloride, in which carbonate replaces chloride as the counterion. While the counterions differ for the two salts, the polymer itself, the active moiety involved in phosphate binding, is the same.

Renvela (sevelamer carbonate) is indicated for the control of serum phosphorus in patients with chronic kidney disease (CKD) on dialysis.  ®

Published Studies Related to Renvela (Sevelamer)

Sevelamer carbonate lowers serum phosphorus effectively in haemodialysis patients: a randomized, double-blind, placebo-controlled, dose-titration study. [2014]
transitioning from a calcium-based to a polymer-based phosphate binder... CONCLUSIONS: This study demonstrated that hyperphosphataemia developed quickly

Effect of gastric acid suppression with pantoprazole on the efficacy of sevelamer hydrochloride as a phosphate binder in haemodialysis patients: a pilot study. [2012]
Sevelamer hydrochloride (HCL) is thought to require an appropriately acidic environment in order to bind gastrointestinal phosphate. Changes in gastric acidity with acid suppressants may therefore alter the efficacy of sevelamer HCL... Although our study did not find a significant drug interaction, given the high prevalence of acid suppressant use in dialysis patients, physicians should be aware of the potential influence of acid suppression on the efficacy of phosphate binders and regularly assess the clinical need for acid suppression therapy.

Comparison of Calcium Acetate and Sevelamer on Vascular Function and Fibroblast Growth Factor 23 in CKD Patients: A Randomized Clinical Trial. [2011.11.30]
BACKGROUND: Fibroblast growth factor 23 (FGF-23) is a marker of endothelial dysfunction and atherosclerotic complications in patients with chronic kidney disease (CKD). Because previous studies suggested that sevelamer may exert effects on FGF-23 level and endothelial function independently of its phosphate-lowering action, we tested the effect of sevelamer versus calcium acetate on vascular function and FGF-23 levels... CONCLUSIONS: In hyperphosphatemic patients with stage 4 CKD, treatment with phosphate lowering induces measurable improvements in flow-mediated vasodilatation. Furthermore, independently of serum phosphate level, FGF-23 level changes induced by phosphate binders are associated with simultaneous changes in flow-mediated vasodilatation. These observations are compatible with the hypothesis that FGF-23 may contribute to vascular dysfunction in this population. Copyright (c) 2011 National Kidney Foundation, Inc.

Comparison of dietary phosphate absorption after single doses of lanthanum carbonate and sevelamer carbonate in healthy volunteers: a balance study. [2011.05]
BACKGROUND: Lanthanum carbonate and sevelamer carbonate are noncalcium phosphate binders used to treat hyperphosphatemia in patients with chronic kidney disease. This is the first study to compare phosphate absorption from a standardized meal ingested with a typical clinical dose of these binders... CONCLUSIONS: In healthy volunteers, 1,000 mg of lanthanum carbonate decreased phosphate absorption by 45% compared with a 21% decrease with 2,400 mg of sevelamer carbonate.

The effect of sevelamer carbonate and lanthanum carbonate on the pharmacokinetics of oral calcitriol. [2011.05]
BACKGROUND: Lanthanum carbonate and sevelamer carbonate are non-calcium-based phosphate binders used to manage hyperphosphataemia in patients with chronic kidney disease (CKD). Patients with CKD may require intravenous or oral active vitamin D. We investigated the effects of lanthanum carbonate and sevelamer carbonate on the bioavailability of oral calcitriol... CONCLUSIONS: Sevelamer carbonate significantly reduces serum concentrations of exogenous calcitriol when administered concomitantly with oral calcitriol, whereas lanthanum carbonate has no significant effect. This should be considered when treating CKD patients who require phosphate binders and oral vitamin D.

Clinical Trials Related to Renvela (Sevelamer)

Nicotinamide Versus Sevelamer Hydrochloride on Phosphatemia Control on Chronic Hemodialysed Patients [Recruiting]
The comparison between nicotinamide and sevelamer aims to demonstrate, in chronic hemodialysed patients, the non-inferiority of nicotinamide in terms of control of the phosphatemia. Secondary objectives is to compare the two treatments in terms of efficiency in other biological parameters, vascular calcification and bone mass loss and on the clinical and biological tolerance and finally to explore the roles of metabolites of nicotinamide.

The Effect(s) of Sevelamer Carbonate (Renvela) on Atherosclerotic Plaque Inflammation Judged by FDG-PET Scan [Recruiting]
The hypothesis is that switching calcium based phosphate binders to sevelamer carbonate will be associated with less inflammation including less atherosclerotic plaque inflammation (inflammation of the vessel walls).

Sevelamer for Reducing Endotoxemia and Immune Activation [Completed]
HIV-infected people can have an increase in inflammation in their body organs, even after taking anti-HIV medicines. Sevelamer carbonate is used to bind phosphate in dialysis patients. It can also bind endotoxin in the gut and lowers endotoxin levels in the blood of dialysis patients. Sevelamer carbonate decreases the inflammation endotoxin causes in dialysis patients. A5296 is a phase II, single-arm study to evaluate the effect of 8 weeks of sevelamer carbonate administration on markers of microbial translocation and T-cell activation in the blood in chronically HIV-infected subjects not receiving ART.

A Phase 1 Study to Examine the Effect of Renvela on the Pharmacodynamics of AZD1722 [Completed]

Randomized Study Comparing Genz-644470, Placebo, and Sevelamer Carbonate in Chronic Kidney Disease Patients on Hemodialysis [Completed]
The purpose of this clinical study is to compare the effects of Genz-644470 with the effects of placebo and sevelamer carbonate (Renvela) on the reduction of serum phosphorus in hyperphosphatemic chronic kidney disease participants on hemodialysis.
