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)
Effect of gastric acid suppression with pantoprazole on the efficacy of sevelamer
hydrochloride as a phosphate binder in haemodialysis patients: a pilot study. 
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.
Effect of sevelamer and calcium-based phosphate binders on coronary artery calcification and accumulation of circulating advanced glycation end products in hemodialysis patients. [2011.03]
BACKGROUND: Some trials have indicated that coronary artery calcification progresses more slowly in sevelamer-treated dialysis patients than in those using calcium-based binders. Effects of phosphate binders on circulating advanced glycation end products (AGEs) are unknown... CONCLUSIONS: The data suggest that sevelamer treatment slowed the increase in CACS and suppressed AGE accumulation. Copyright (c) 2011 National Kidney Foundation, Inc. Published by Elsevier Inc.

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).
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
Effect of Sevelamer on Glucose Tolerance and Insulin Sensitivity in Patients With Chronic Renal Failure (CKD) [Recruiting]
FGF23 Reduction : Efficacy of a New Phosphate Binder in CHronic Kidney Disease [Recruiting]
The purpose of this study is to evaluate in Chronic Kidney Disease (CKD) patients not on
dialysis and who have an Fibroblast growth factor 23 (FGF23) serum levels elevated, the
effect of non calcic phosphate binder: sevelamer carbonate. This treatment could lead to a
diminution of FGF23 serum levels due to the diminution of intestinal absorption of dietary
phosphate. In addition, the investigators will describe the impact of the FGF23 level
monitoring on the main phosphocalcium metabolism markers as phosphatemia, intact parathyroid
hormone (iPTH), serum calcitriol and phosphaturia.
