🩺 Clinical
Cinacalcet is used to treat hyperparathyroidism (a condition in which the body produces too much parathyroid hormone [a natural substance needed to control the amount of calcium in the blood] which can cause serious problems with the bones, heart, blood vessels, and lungs) in people with chronic kidney disease (condition in which the kidneys stop working slowly and gradually) who are being treated with dialysis. Cinacalcet is also used to treat high levels of calcium in the blood of patients who have parathyroid cancer (cancer of the glands in the neck that make parathyroid hormone). Cinacalce...

Hypercalcemia in adult patients with Parathyroid Carcinoma (PC). (1.2) Severe hypercalcemia in adult patients with primary HPT who are unable to undergo parathyroidectomy.
(1.3)
1.1Secondary Hyperparathyroidism Cinacalcet are indicated for the treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on dialysis [see Clinical Studies ( 14.1 )]. Limitations of Use: Cinacalcet is not indicated for use in adult patients with CKD who are not on dialysis because of an increased risk of hypocalcemia [see Warnings and Precautions ( 5.1 )].
1.2Parathyroid Carcinoma Cinacalcet is indicated for the treatment of hypercalcemia in adult patients with Parathyroid Carcinoma [see Clinical Studies ( 14.2) ] .
1.3Primary Hyperparathyroidism Cinacalcet are indicated for the treatment of severe hypercalcemia in adult patients with primary HPT who are unable to undergo parathyroidectomy [ see Clinical Studies (14.3) ].
⏱️ Dosage and Administration ▾
2 DOSAGE & ADMINISTRATION Cinacalcet tablets should be taken with food or shortly after a meal (2.1). Tablets should always be taken whole and not divided (2.1) Secondary HPT in patients with CKD on dialysis (2.2) : Starting dose is 30 mg once daily. Titrate dose no more frequently than every 2 to 4 weeks through sequential doses of 30, 60, 90, 120, and 180 mg once daily as necessary to achieve targeted intact parathyroid hormone (iPTH) levels. iPTH levels should be measured no earlier than 12 hours after most recent dose.
Hypercalcemia in Patients with PC or severe hypercalcemia in patients with primary HPT (2.3). Starting dose is 30 mg twice daily. Titrate dose every 2 to 4 weeks through sequential doses of 30 mg twice daily, 60 mg twice daily, 90 mg twice daily, and 90 mg three or four times daily as necessary to normalize serum calcium levels.
Once the maintenance dose has been established, monitor serum calcium approximately monthly for patients with secondary HPT and every 2 months for patients with PC or primary HPT (2.4)
2.1Administration Cinacalcet Tablets should be taken with food or shortly after a meal. Cinacalcet Tablets are administered orally and should always be taken whole and not chewed, crushed, or divided.
2.2Secondary Hyperparathyroidism in Patients with Chronic Kidney Disease on Dialysis The recommended starting oral dose of cinacalcet is 30 mg once daily. Serum calcium and serum phosphorus should be measured within 1 week and intact parathyroid hormone (iPTH) should be measured 1 to 4 weeks after initiation or dose adjustment of cinacalcet [see Dosage and Administration (2.3)] . Cinacalcet should be titrated no more frequently than every 2 to 4 weeks through sequential doses of 30, 60, 90, 120, and 180 mg once daily to target iPTH levels of 150 to 300 pg/mL.
Serum iPTH levels should be assessed no earlier than 12 hours after dosing with cinacalcet . Cinacalcet can be used alone or in combination with vitamin D sterols and/or phosphate binders. During dose titration, serum calcium levels should be monitored frequently and if levels decrease below the normal range, appropriate steps should be taken to increase serum calcium levels, such as by providing supplemental calcium, initiating or increasing the dose of calcium-based phosphate binder, initiating or increasing the dose of vitamin D sterols, or temporarily withholding treatment with cinacalcet [see Dosage and Administration ( 2.4 ) and Warnings and Precautions (5.1)] .
2.3Patients with Parathyroid Carcinoma and Primary Hyperparathyroidism The recommended starting oral dose of cinacalcet is 30 mg twice daily. The dose of cinacalcet should be titrated every 2 to 4 weeks through sequential doses of 30 mg twice daily, 60 mg twice daily, and 90 mg twice daily, and 90 mg 3 or 4 times daily as necessary to normalize serum calcium levels. Serum calcium should be measured within 1 week after initiation or dose adjustment of cinacalcet [ see Dosage and Administration (2.4) and Warnings and Precautions (5.1)].
2.4Switching from Parsabiv (etelcalcetide) to cinacalcet Discontinue etelcalcetide for at least 4 weeks prior to starting cinacalcet. Ensure corrected serum calcium is at or above the lower limit of normal prior to cinacalcet initiation [see Warnings and Precautions (5.1)] . Initiate cinacalcet treatment at a starting dose of 30 mg once daily.
2.5Monitoring for Hypocalcemia Once the maintenance dose has been established, serum calcium should be measured approximately monthly for patients with secondary hyperparathyroidism with CKD on dialysis, and every 2 months for patients with parathyroid carcinoma or primary hyperparathyroidism [ see Dosage and Administration (2.2 , 2.3)] . For secondary hyperparathyroidism patients with CKD on dialysis, if serum calcium falls below 8.4 mg/dL but remains above 7.5 mg/dL, or if symptoms of hypocalcemia occur, calcium-containing phosphate binders and/or vitamin D sterols can be used to raise serum calcium.

Cinacalcet treatment initiation is contraindicated if serum calcium is less than the lower limit of the normal range. ( 4 , 5.1 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypocalcemia: Life threatening events and fatal outcomes were reported. Hypocalcemia can prolong QT interval, lower the threshold for seizures, and cause hypotension, worsening heart failure, and/or arrhythmia. Monitor serum calcium carefully for the occurrence of hypocalcemia during treatment (2.4, 5.1) Upper Gastrointestinal (GI) Bleeding: Patients with risk factors for upper GI bleeding may be at increased risk.
Monitor patients and promptly evaluate and treat any suspected GI bleeding. (5.2) Hypotension, Worsening Heart Failure and/or Arrhythmias: In postmarketing safety surveillance, isolated, idiosyncratic cases of hypotension, worsening heart failure, and/or arrhythmia have been reported in patients with impaired cardiac function. (5.3) Adynamic Bone Disease: May develop if iPTH levels are suppressed below 100 pg/mL.
(5.4)
5.1Hypocalcemia Cinacalcet lowers serum calcium and can lead to hypocalcemia [see Adverse Reactions (6.1)] . Significant lowering of serum calcium can cause paresthesias, myalgias, muscle spasms, tetany, seizures, QT interval prolongation and ventricular arrhythmia. Life threatening events and fatal outcomes associated with hypocalcemia have been reported in patients treated with cinacalcet, including in pediatric patients.
The safety and effectiveness of cinacalcet have not been established in pediatric patients [see Pediatric Use (8.4)]. Cinacalcet is not indicated for patients with CKD not on dialysis [see Indications and Usage (1)] . In patients with secondary HPT and CKD not on dialysis, the long term safety and efficacy of cinacalcet have not been established.
Clinical studies indicate that cinacalcet-treated patients with CKD not on dialysis have an increased risk for hypocalcemia compared with cinacalcet-treated patients with CKD on dialysis, which may be due to lower baseline calcium levels. In a phase 3 study of 32 weeks duration and including 404 patients with CKD not on dialysis (302 cinacalcet, 102 placebo), in which the median dose for cinacalcet was 60 mg per day at the completion of the study, 80% of cinacalcet-treated patients experienced at least one serum calcium value < 8.4 mg/dL compared with 5% of patients receiving placebo.
QT Interval Prolongation and Ventricular Arrhythmia Decreases in serum calcium can also prolong the QT interval, potentially resulting in ventricular arrhythmia. Cases of QT prolongation and ventricular arrhythmia have been reported in patients treated with cinacalcet. Patients with congenital long QT syndrome, history of QT interval prolongation, family history of long QT syndrome or sudden cardiac death, and other conditions that predispose to QT interval prolongation and ventricular arrhythmia may be at increased risk for QT interval prolongation and ventricular arrhythmias if they develop hypocalcemia due to cinacalcet.
Closely monitor corrected serum calcium and QT interval in patients at risk receiving cinacalcet. Seizures In clinical studies, seizures (primarily generalized or tonic-clonic) were observed in 1.4% (43/3049) of cinacalcet-treated patients and 0.7% (5/687) of placebo-treated patients. While the basis for the reported difference in seizure rate is not clear, the threshold for seizures is lowered by significant reductions in serum calcium levels.
Monitor serum calcium levels in patients with seizure disorders receiving cinacalcet. Concurrent Administration with Other Calcium-Lowering Drug Products Concurrent administration of cinacalcet with calcium-lowering drugs including other calcium-sensing receptor agonists could result in severe hypocalcemia. Closely monitor serum calcium in patients receiving cinacalcet and concomitant therapies known to lower serum calcium levels.
Patient Education and Hypocalcemia Treatment Educate patients on the symptoms of hypocalcemia and advise them to contact a healthcare provider if they occur. If corrected serum calcium falls below the lower limit of normal or symptoms of hypocal…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Secondary Hyperparathyroidism in Patients with Chronic Kidney Disease on Dialysis In three double-blind, placebo-controlled clinical trials, 1126 patients with CKD on dialysis received study drug (656 cinacalcet, 470 placebo) for up to 6 months.
The most frequently reported adverse reactions are listed in Table 1. Seizures were observed in 1.4% (13/910) of cinacalcet-treated patients and 0.7% (5/641) of placebo-treated patients across all completed placebo controlled trials. Table 1.

Patients with Parathyroid Carcinoma and Primary Hyperparathyroidism The safety profile of cinacalcet in these patient populations is generally consistent with that seen in patients with CKD on dialysis. Forty six patients were treated with cinacalcet in a single arm study, 29 with Parathyroid Carcinoma and 17 with intractable pHPT. Nine (20%) of the patients withdrew from the study due to adverse events.
The most frequent adverse reactions and the most frequent cause of withdrawal in these patient populations were nausea and vomiting. Severe or prolonged cases o…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Co-administration with a strong CYP3A4 inhibitor may increase serum levels of cinacalcet. Dose adjustment and monitoring of iPTH serum phosphorous and serum calcium may be required. ( 7.1 ) Cinacalcet is a strong inhibitor of CYP2D6. Dose adjustments may be required for concomitant medications that are predominantly metabolized by CYP2D6. ( 7.2 )
7.1Strong CYP3A4 Inhibitors Cinacalcet is partially metabolized by CYP3A4. Dose adjustment of cinacalcet may be required if a patient initiates or discontinues therapy with a strong CYP3A4 inhibitor (e.g., ketoconazole, itraconazole). The iPTH and serum calcium concentrations should be closely monitored in these patients [see Clinical Pharmacology (12.3)] .
7.2CYP2D6 Substrates Cinacalcet is a strong inhibitor of CYP2D6. Dose adjustments may be required for concomitant medications that are predominantly metabolized by CYP2D6 (e.g., desipramine, metoprolol, and carvedilol) and particularly those with a narrow therapeutic index (e.g., flecainide and most tricyclic antidepressants) [see Clinical Pharmacology ( 12.3) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pediatric Use: A fatal outcome was reported in a pediatric clinical trial patient with severe hypocalcemia. Cinacalcet is not indicated for use in pediatric patients ( 8.4 ).
8.1Pregnancy Risk Summary Limited case reports of cinacalcet use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. In animal reproduction studies, when female rats were exposed to cinacalcet during the period of organogenesis through to weaning at 2-3 times the systemic drug levels (based on AUC) at the maximum recommended human dose (MRHD) of 180 mg/day, peripartum and early postnatal pup loss and reduced pup body weight gain were observed in the presence of maternal hypocalcemia [see Data].
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In pregnant female rats given oral gavage doses of 2, 25, 50 mg/kg/day cinacalcet during gestation, no teratogenicity was observed at doses up to 50 mg/kg/day (exposure 4 times those resulting with a human oral dose of 180 mg/day based on AUC comparison).
Decreased fetal body weights were observed at all doses (less than 1 to 4 times a human oral dose of 180 mg/day based on AUC comparison) in conjunction with maternal toxicity (decreased food consumption and body weight gain). In pregnant female rabbits given oral gavage doses of 2, 12, 25 mg/kg/day cinacalcet during gestation, no adverse fetal effects were observed (exposures less than with a human oral dose of 180 mg/day based on AUC comparisons). Reductions in maternal food consumption and body weight gain were seen at doses of 12 and 25 mg/kg/day.
Cinacalcet has been shown to cross the placental barrier in rabbits. In pregnant rats given oral gavage doses of 5, 15, 25 mg/kg/day cinacalcet during gestation through lactation, no adverse fetal or pup (post-weaning) effects were observed at 5 mg/kg/day (exposures less than with a human therapeutic dose of 180 mg/day based on AUC comparisons). Higher doses of 15 and 25 mg/kg/day cinacalcet (exposures 2 to 3 times a human oral dose of 180 mg/day based on AUC comparisons) were accompanied by maternal signs of hypocalcemia (periparturient mortality and early postnatal pup loss), and reductions in postnatal maternal and pup body-weight gain.
8.2Lactation Risk Summary There are no data regarding the presence of cinacalcet in human milk or effects on the breastfed infant or on milk production. Studies in rats showed that cinacalcet was excreted in the milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for cinacalcet and any potential adverse effects on the breastfed infant from cinacalcet or from the underlying maternal condition.
8.4Pediatric Use The safety and efficacy of cinacalcet have not been established in pediatric patients. The use of cinacalcet for the treatment of secondary HPT in pediatric patients with CKD on dialysis was evaluated in two randomized, controlled studies (Pediatric Study 1 and Study 2) where 47 pediatric patients aged 6 years to less than 18 years received at least one dose of cinacalcet and in one single-arm study (Pediatric Study 3) where 17 pediatric patients aged 28 days to less than 6 years received at least one dose of cinacalcet.

🤰 Pregnancy ▾
8.1Pregnancy Risk Summary Limited case reports of cinacalcet use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. In animal reproduction studies, when female rats were exposed to cinacalcet during the period of organogenesis through to weaning at 2-3 times the systemic drug levels (based on AUC) at the maximum recommended human dose (MRHD) of 180 mg/day, peripartum and early postnatal pup loss and reduced pup body weight gain were observed in the presence of maternal hypocalcemia [see Data].
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In pregnant female rats given oral gavage doses of 2, 25, 50 mg/kg/day cinacalcet during gestation, no teratogenicity was observed at doses up to 50 mg/kg/day (exposure 4 times those resulting with a human oral dose of 180 mg/day based on AUC comparison).
Decreased fetal body weights were observed at all doses (less than 1 to 4 times a human oral dose of 180 mg/day based on AUC comparison) in conjunction with maternal toxicity (decreased food consumption and body weight gain). In pregnant female rabbits given oral gavage doses of 2, 12, 25 mg/kg/day cinacalcet during gestation, no adverse fetal effects were observed (exposures less than with a human oral dose of 180 mg/day based on AUC comparisons). Reductions in maternal food consumption and body weight gain were seen at doses of 12 and 25 mg/kg/day.
Cinacalcet has been shown to cross the placental barrier in rabbits. In pregnant rats given oral gavage doses of 5, 15, 25 mg/kg/day cinacalcet during gestation through lactation, no adverse fetal or pup (post-weaning) effects were observed at 5 mg/kg/day (exposures less than with a human therapeutic dose of 180 mg/day based on AUC comparisons). Higher doses of 15 and 25 mg/kg/day cinacalcet (exposures 2 to 3 times a human oral dose of 180 mg/day based on AUC comparisons) were accompanied by maternal signs of hypocalcemia (periparturient mortality and early postnatal pup loss), and reductions in postnatal maternal and pup body-weight gain.
🧒 Pediatric Use ▾
8.4Pediatric Use The safety and efficacy of cinacalcet have not been established in pediatric patients. The use of cinacalcet for the treatment of secondary HPT in pediatric patients with CKD on dialysis was evaluated in two randomized, controlled studies (Pediatric Study 1 and Study 2) where 47 pediatric patients aged 6 years to less than 18 years received at least one dose of cinacalcet and in one single-arm study (Pediatric Study 3) where 17 pediatric patients aged 28 days to less than 6 years received at least one dose of cinacalcet.
Dosing with cinacalcet in pediatric study 1 was stopped because of a fatality in a cinacalcet-treated individual. The individual was noted to be severely hypocalcemic at the time of death. The cause of death was multifactorial and a contribution of cinacalcet to the death could not be excluded [see Warnings and Precautions (5.1) ].
Study 1 was terminated and changes to cinacalcet dosing after the fatality were implemented in Pediatric Study 2 and Study 3 to minimize the risk of severe hypocalcemia. The data in Pediatric Studies 2 and 3 were insufficient to establish the safety and efficacy of cinacalcet for the treatment of secondary HPT in pediatric patients with CKD on dialysis. In aggregate, the pediatric studies did not establish a safe and effective cinacalcet dosing regimen for the pediatric population.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of subjects (n=1136) in clinical studies of cinacalcet, 26 percent were 65 and over, and 9 percent were 75 and over. No overall differences in the safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Studies ( 14 ) and Clinical Pharmacology ( 12.3 )] .
🆘 Overdosage ▾
10 OVERDOSAGE Overdosage of cinacalcet may lead to hypocalcemia. In the event of overdosage, patients should be monitored for signs and symptoms of hypocalcemia and appropriate measures taken to correct serum calcium levels [see Warnings and Precautions (5.1)]. Since cinacalcet is highly protein bound, hemodialysis is not an effective treatment for overdosage of cinacalcet .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The calcium-sensing receptor on the surface of the chief cell of the parathyroid gland is the principal regulator of PTH synthesis and secretion. Cinacalcet, the active ingredient in cinacalcet tablets, is a calcimimetic agent that directly lowers PTH levels by increasing the sensitivity of the calcium-sensing receptor to activation by extracellular calcium. The reduction in PTH is associated with a concomitant decrease in serum calcium levels.
12.2Pharmacodynamics Reduction in iPTH levels correlated with the plasma cinacalcet concentrations in patients with CKD. The nadir in iPTH level occurs approximately 2 to 6 hours post dose, corresponding with the maximum plasma concentration (C max ) of cinacalcet. After steady-state cinacalcet concentrations are reached (which occurs within 7 days of dose change), serum calcium concentrations remain constant over the dosing interval in patients with CKD.
Reductions in PTH are associated with a decrease in bone turnover and bone fibrosis in patients with CKD on dialysis and uncontrolled secondary HPT.
12.3Pharmacokinetics Absorption and Distribution After oral administration of cinacalcet, C max is achieved in approximately 2 to 6 hours. Cinacalcet C max and AUC( 0-infinite ) were increased by 82% and 68%, respectively, following administration with a high-fat meal compared with fasting in healthy volunteers. The C max and AUC( 0-infinite ) of cinacalcet were increased by 65% and 50%, respectively, when cinacalcet was administered with a low-fat meal compared with fasting.
After absorption, cinacalcet concentrations decline in a biphasic fashion with an initial half-life of approximately 6 hours and terminal half-life of 30 to 40 hours. Steady-state drug levels are achieved within 7 days, and the mean accumulation ratio is approximately 2 with once daily oral administration. The median accumulation ratio is approximately 2 to 5 with twice daily oral administration.
The AUC and C max of cinacalcet increase proportionally over the dose range of 30 to 180 mg once daily. The pharmacokinetic profile of cinacalcet does not change over time with once daily dosing of 30 to 180 mg. The volume of distribution is approximately 1000 L, indicating extensive distribution.
Cinacalcet is approximately 93% to 97% bound to plasma protein(s). The ratio of blood cinacalcet concentration to plasma cinacalcet concentration is 0.80 at a blood cinacalcet concentration of 10 ng/mL. Metabolism and Excretion Cinacalcet is metabolized by multiple enzymes, primarily CYP3A4, CYP2D6, and CYP1A2.
After administration of a 75 mg radiolabeled dose to healthy volunteers, cinacalcet was metabolized via: 1) oxidative N-dealkylation to hydrocinnamic acid and hydroxy-hydrocinnamic acid, which are further metabolized via β-oxidation and glycine conjugation; the oxidative N-dealkylation process also generates metabolites that contain the naphthalene ring; and 2) oxidation of the naphthalene ring on the parent drug forming dihydrodiols, which are further conjugated with glucuronic acid. The plasma concentrations of the major circulating metabolites, including the cinnamic acid derivatives and glucuronidated dihydrodiols, markedly exceed the parent drug concentrations.
The hydrocinnamic acid metabolite and glucuronide conjugates have minimal or no calcimimetic activity. Renal excretion of metabolites was the primary route of elimination of radioactivity. Approximately 80% of the dose was recovered in the urine and 15% in the feces.
Specific Populations Age: Geriatric Population The pharmacokinetic profile of cinacalcet in geriatric patients (age ≥ 65 years, n = 12) is similar to that for patients who are < 65 years of age (n = 268) [see Use in Specific Populations ( 8.5) ] . Hepatic Impairment The disposition of a 50 mg cinacalcet single dose was compared between patients with hepatic impairment and patients with normal hepatic function. Cinacalcet exposure (AUC( 0-infinite ))…
