Published Studies Related to Renagel (Sevelamer)
Sevelamer carbonate lowers serum phosphorus effectively in haemodialysis
patients: a randomized, double-blind, placebo-controlled, dose-titration study. 
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. 
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 Renagel (Sevelamer)
Study to Demonstrate Equivalence of Sevelamer Carbonate Powder and Sevelamer Hydrochloride Tablets in Haemodialysis Patients [Completed]
The purpose of this study is to determine if sevelamer carbonate powder is an effective
treatment for the control of serum phosphorous levels in patients on dialysis when compared
to sevelamer hydrochloride tablets.
Study to Compare Sevelamer Carbonate Powder to Sevelamer Hydrochloride Tablets in Patients With Chronic Kidney Disease on Hemodialysis [Completed]
Approximately 207 patients with chronic kidney disease (CKD) on hemodialysis will be entered
into this study at approximately 26 centers in the United States. This study aims to
evaluate the safety and efficacy of sevelamer carbonate powder dosed once-a-day (QD) with the
largest meal compared to sevelamer hydrochloride tablets dosed three-times-per-day (TID) with
meals. The total length of participation is approximately 24 weeks.
CARE-2 (Calcium Acetate [PhosLoŽ]/Sevelamer[RenagelŽ] Evaluation Study 2) for Heart Calcification in Dialysis Patients [Completed]
The purpose of the study is to evaluate the effects of two phosphate binders, PhosLo and
sevelamer, on heart calcification in dialysis patients. The study will use a non-invasive
technique, electron beam computed tomography (CT) scanning, to measure calcium in the
coronary arteries, the aortic valve, and the mitral valve.
Cross-Over Study of Sevelamer Hydrochloride and Sevelamer Carbonate [Completed]
This is a double-blind, randomized, cross-over study conducted at centers within the United
States. The study consists of five periods: an up to two-week Screening Period, a 5-week
Run-In Period, two eight-week study treatment periods and a two-week Washout Period.
Patients are assigned randomly (1: 1) to one of two treatment sequences: sevelamer carbonate
for eight weeks followed by sevelamer hydrochloride for eight weeks or sevelamer
hydrochloride for eight weeks followed by sevelamer carbonate for eight weeks
Study of Safety and Efficacy of RenagelŽ Compared With Calcium Acetate in Patients With Peritoneal Dialysis [Completed]
The purpose of this study is to determine if RenagelŽ is more effective as a treatment for
patients with peritoneal dialysis compared to calcium acetate.
