Filter by:The primary objective of the study was to evaluate the safety and tolerability of cinacalcet after a single oral dose in children aged 28 days to less than 6 years with chronic kidney disease receiving dialysis.
The purpose of this study is to assess the safety and efficacy of adding cinacalcet to the current treatment of secondary hyperparathyroidism in children currently receiving dialysis compared to a treatment regimen that does not include cinacalcet.
Paricalcitol capsules (Zemplar®) received marketing authorization in Sweden in late 2007 for the prevention and treatment of secondary hyperparathyroidism in patients with Stage 3 & 4 Chronic Kidney Disease (CKD). Accordingly, additional data is needed to evaluate the effectiveness and safety of paricalcitol therapy under conditions of usual clinical care in Sweden. This observational study is designed to collect data to evaluate safety and effectiveness during 6 months of therapy with paricalcitol capsules prescribed for patients with CKD Stages 3-5 not yet on dialysis. Data will also be collected on patient quality of life and costs associated with patient care.
The purpose of this study is to characterize the safety and tolerability and efficacy of multiple ascending doses of KAI-4169 in hemodialysis subjects for the treatment of secondary hyperparathyroidism.
The aims of this post-marketing observational study (PMOS) are to evaluate the time period needed to achieve > 30% decrease of intact parathyroid hormone (iPTH) compared to the initial values and to provide data on the tolerability and compliance of treatment with Zemplar (paricalcitol) capsules in the therapy of secondary hyperparathyroidism (SHPT) in patients with chronic kidney disease (CKD) stage 3 or 4 in conditions of routine clinical practice.
The risk of fracture for kidney transplant recipients is 4 times higher that of the general population. The hyperparathyroidism plays a key role in the maintenance or development of post-transplant alterations of bone remodelling. Renal transplant patients are at high risk of hyperparathyroidism, largely because of long-lasting renal insufficiency before transplant, and of progressive deterioration of kidney function because of chronic allograft nephropathy (a disease of proteinuria and progressive decline of the glomerular filtration rate).In hemodialysis patients, intravenous paricalcitol (19-nor-1,25-dihydroxyvitamin D2), a new vitamin D analogue, achieves a faster and more effective normalization of parathyroid hormone (PTH) levels than calcitriol (1,25-dihydroxyvitamin D3), an effect that is associated with smaller changes in serum calcium and phosphorus levels. Whether oral paricalcitol may help achieving a prompt reduction in serum PTH levels and, secondarily, in urinary protein excretion in renal transplant recipients with secondary hyperparathyroidism is worth investigating.
This study will investigate how the levels of a repeat dose of CTAP101 changes in the body over time (pharmacokinetics, PK) and how CTAP101 affects other mineral and hormonal balances (pharmacodynamics, PD) in patients with chronic kidney disease (CKD, vitamin D insufficiency and secondary hyperparathyroidism (SHPT).
The hypothesis underlying this study is that phosphate interferes with PTH-mediated calcium reabsorption in the distal nephron and thereby necessitates supranormal [PTH]to maintain normocalcemia in chronic kidney disease. This study will examine the hypothesis with measures of phosphate homeostasis and calcium reabsorption. A double-blind trial of the intestinal phosphate binder sevelamer carbonate will be employed to examine whether reductions in phosphate influx alter distal nephron phosphate concentration and the [PTH] required for calcium reabsorption in the expected manner.
The purpose of this study is to determine the efficacy of treatment with cinacalcet to manage plasma parathyroid levels as to compared traditional vitamin D therapy, whether given orally or intravenously, among hemodialysis subjects with secondary hyperparathyroidism when the doses are adjusted appropriately to maintain serum calcium and phosphorous levels with currently recommended ranges.
The hypothesis of this study is that subtotal parathyroidectomy using minimally invasive surgery is superior to cinacalcet for the treatment of persistent secondary hyperparathyroidism (HPT) post renal transplant, with minimal morbidity and significantly reduces the cost of treatment post transplant.
