Filter by:A long-term study of BAY77-1931 (lanthanum carbonate) for hyperphosphatemia in patients undergoing hemodialysis
To measure lanthanum concentrations in bone in patients with hyperphosphatemia receiving dialysis
To compare the bioequivalence of calcium acetate oral solution vs. calcium acetate gelcaps in healthy volunteers with calcium citrate as a positive control.
This study will evaluate the efficacy of SBR759 compared to sevelamer HCl in lowering serum phosphate levels in Chronic Kidney Disease patients on hemodialysis
Approximately 45 hyperphosphatemic CKD patients not on dialysis will be entered into this study at approximately 20 sites within Europe and 5-10 in Australia. The purpose of this study is to determine if sevelamer carbonate tablets dosed three times a day (TID) is an effective treatment for the control of serum phosphorous levels in hyperphosphatemic CKD patients not on dialysis. Total length of participation is approximately 14 weeks.
Patients with end-stage renal disease (ESRD) commonly develop hyperphosphatemia due to the loss of excretory function of the kidney. This in turn may lead to the development of secondary hyperparathyroidism (SHPT) and renal osteodystrophy. Lanthanum carbonate, a phosphate binding agent, works by releasing lanthanum ions in the gastrointestinal tract to bind dietary phosphate and is effective in the management of hyperphosphatemia and in preventing secondary hyperparathyroidism. Patients taking lanthanum carbonate as part of their phosphate binder therapy are counseled to chew the tablets completely before swallowing, with or immediately after meals. However, ESRD patients who are intubated or are receiving enteral tube feedings are unable to chew the lanthanum carbonate tablets. For such patients, medications are commonly crushed and administered through a gastrostomy tube (G-tube). Some patients may also prefer to crush the lanthanum carbonate tablets and mix it with food instead of chewing. To date, it is not known if crushing the lanthanum carbonate tablets prior to administration and taking it with food will be as efficacious as chewing it. The objective of this study is to compare the efficacy of phosphate binding between chewed and crushed lanthanum carbonate in patients undergoing hemodialysis.
This study is to evaluates the safety and tolerability of Zerenex™ (ferric citrate) as a treatment for hyperphosphatemia in patients with End-Stage Renal Disease.
Specific Aim: To determine the effect of a phosphorus additives educational intervention on serum phosphorus levels. Hypothesis: Educating dialysis patients regarding phosphate containing additives will result in improved serum phosphorus levels.
Patients who have been treated with Fosrenol for a minimum of 12 consecutive weeks and are receiving dialysis will be followed for 5 years to compare mortality, bone fractures and incidence of selected morbidities to patients with no lanthanum exposure and to patients being treated for hyperphosphatemia with any marketed product.
Patients enrolled in a previous study (SPD405-309), who were exposed to lanthanum carbonate (Fosrenol), were eligible to continue on any prescribed treatment for hyperphosphatemia, including lanthanum carbonate (Fosrenol), for an additional 5 years. Patients were being observed for any bone adverse events or other serious adverse events, as well as the collection of mortality data.
