Cinacalcet HCl reduces iPTH, serum calcium, serum phosphorus, and the calcium-phosphorus product in patients with chronic kidney disease and secondary hyperparathyroidism who are receiving dialysis, and reduces elevated serum calcium associated with primary hyperparathyroidism and parathyroid carcinoma. Cinacalcet is administered orally, and thus concomitant administration with food may affect its bioavailability. The objective of this study was to examine the effect of fat and caloric intake on cinacalcet exposure...

BACKGROUND: Calcimimetic agents have recently been evaluated in the treatment of secondary hyperparathyroidism (SHPT) as add-on therapy to calcitriol and vitamin D analogues and dietary phosphate binders. OBJECTIVES: To evaluate the benefits and harms of calcimimetics for the prevention of secondary hyperparathyroid bone disease (including osteitis fibrosa cystica and adynamic bone disease) in dialysis patients with chronic kidney disease (CKD). SEARCH STRATEGY: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and conference proceedings were searched for randomised controlled trials (RCTs) evaluating any calcimimetic against placebo or another agent in pre-dialysis or dialysis patients with CKD...

Calcimimetics suppress the secretion of parathyroid hormone by sensitizing the parathyroid calcium receptor to serum calcium. Cinacalcet (Sensipar/Mimpara), Amgen Inc., Thousand Oaks, CA), the first-in-class calcimimetic agent approved for treatment of secondary hyperparathyroidism in dialysis patients, is, in association with higher dose of a calcium-based oral phosphate binder, a well-tolerated and effective alternative to standard treatments such as vitamin D derivatives in association with a non-calcium-based oral phosphate binder...

Currently, >300,000 patients with end-stage renal disease require dialysis. Secondary hyperparathyroidism is a serious complication of end-stage renal disease and can lead to renal osteodystrophy and other organ failure. Vitamin D sterols and phosphate binders are used to treat hyperparathyroidism, but they can cause hypercalcemia, which contributes to vascular and soft-tissue calcification. Cinacalcet (Sensipar) is the first agent in its class that treats secondary hyperparathyroidism by increasing the sensitivity of calcium sensing receptors...

As suggested by its American brand name (Sensipar), the calcimimetic cinacalcet sensitizes the parathyroid cells to the extracellular calcium signal, suppressing parathyroid hormone (PTH) release and synthesis and preventing parathyroid cell proliferation. This primary PTH suppression decreases the release of calcium and phosphate from bone without increasing intestinal absorption of calcium and phosphate. Therefore cinacalcet decreases the risk of hypercalcemia and hyperphosphatemia in contrast to 1alpha-OH vitamin D derivatives...

OBJECTIVE: Cinacalcet (cinacalcet HCl; Sensipar/Mimpara) is a calcimimetic that is a treatment for secondary hyperparathyroidism in patients with renal failure. The objective of this study was to assess the effects of renal function and dialysis on the pharmacokinetics and pharmacodynamics of cinacalcet. METHODS: Two open-label, single-dose (75 mg) studies of cinacalcet were performed: study 1 examined 36 subjects who had renal function ranging from normal to requiring haemodialysis, and study 2 examined ten subjects who were receiving continuous ambulatory peritoneal dialysis...

BACKGROUND: Calcitriol treatment of secondary hyperparathyroidism (HPT) in chronic kidney disease (CKD) patients can lead to increased serum calcium and phosphorus, which have been associated as risk factors for vascular calcification. Cinacalcet HCl (Sensipar/Mimpara) {(alphaR)-(-)-alpha-methyl-N-[3-[3-(trifluoromethylphenyl)propyl]-1-napthalenemethanamine hydrochloride} lowers serum parathyroid hormone (PTH), calcium, phosphorus and calcium-phosphorous (CaxP) product in stage 5 CKD dialysis patients; however, its effects on vascular calcification are unknown...

Hyperparathyroidism (HPT) is a significant clinical concern for patients with a variety of diseases, notably the secondary HPT associated with chronic kidney disease requiring dialysis. Secondary HPT is associated with elevated para-thyroid hormone (PTH) levels, decreased levels of 1,25 dihydroxyvitamin D, and disordered mineral levels (usually high calcium and phosphorus). If not controlled, secondary HPT can result in bone disease, vascular calcification, and ultimately, patient mortality. Established, conventional therapies, such as 1,25dihydroxyvitamin D analogues (vitamin D analogues) and phosphate binders, have proven to be inadequate in enabling patients to meet the National Kidney Foundation's-Kidney Disease Outcomes Quality Initiative (NKF-K/DOQI) treatment goals for PTH, calcium and phosphorus levels...

Oral cinacalcet hydrochloride (HCl) [Sensipar, Mimpara] is the first in a new class of therapeutic agents, the calcimimetics, and has a novel mechanism of action. It directly modulates the principal regulator of parathyroid hormone (PTH) secretion, namely the calcium-sensing receptor (CaR) on the chief cells in the parathyroid gland. Cinacalcet HCl reduces circulating PTH levels by increasing the sensitivity of the CaR to extracellular calcium. In three pivotal phase III, 26-week, randomised, double-blind, multicentre trials in chronic kidney disease (CKD) patients (n = 1136) on dialysis with uncontrolled secondary hyperparathyroidism (HPT), a significantly higher proportion of oral cinacalcet HCl 30-180 mg/day than placebo recipients achieved a reduction in intact PTH levels to < or =250 pg/mL...
