Study to Compare Sevelamer Carbonate Powder to Sevelamer Hydrochloride Tablets in Patients With CKD on Hemodialysis - Full Text View

Sponsored by:	Genzyme
Information provided by:	Genzyme
ClinicalTrials.gov Identifier:	NCT00268957

Purpose

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.

Primary Outcome Measures:

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 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]
Evaluate the safety and tolerability of sevelamer carbonate powder dosed QD with the largest meal compared to sevelamer hydrochloride tablets dosed TID with meals [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
