Calcitriol:


INDICATIONS AND USAGE

Predialysis Patients

Calmos-CM capsule is indicated in the management of secondary hyperparathyroidism and resultant metabolic bone disease in patients with moderate to severe chronic renal failure (Ccr 15 to 55 mL/min) not yet on dialysis. In children, the creatinine clearance value must be corrected for a surface area of 1.73 square meters. A serum iPTH level of ≥ 100 pg/mL is strongly suggestive of secondary hyperparathyroidism.

Dialysis Patients

Calmos-CM (Calcitriol) capsule is indicated in the management of hypocalcemia and the resultant metabolic bone disease in patients undergoing chronic renal dialysis. In these patients, Calmos-CM (Calcitriol) administration enhances calcium absorption, reduces serum alkaline phosphatase levels, and may reduce elevated parathyroid hormone levels and the histological manifestations of osteitis fibrosa cystica and defective mineralization.

Hypoparathyroidism Patients

Calmos-CM (Calcitriol) capsule is also indicated in the management of hypocalcemia and its clinical manifestations in patients with postsurgical hypoparathyroidism, idiopathic hypoparathyroidism, and pseudohypoparathyroidism.

CONTRAINDICATIONS

Calmos-CM (Calcitriol) should not be given to patients with hypercalcemia or evidence of vitamin D toxicity. Use of Calmos-CM (Calcitriol) in patients with known hypersensitivity to Calmos-CM (Calcitriol) (or drugs of the same class) or any of the inactive ingredients is contraindicated.

WARNINGS

Overdosage of any form of vitamin D is dangerous (see OVERDOSAGE ). Progressive hypercalcemia due to overdosage of vitamin D and its metabolites may be so severe as to require emergency attention. Chronic hypercalcemia can lead to generalized vascular calcification, nephrocalcinosis and other soft-tissue calcification. The serum calcium times phosphate (Ca x P) product should not be allowed to exceed 70 mg2/dL2. Radiographic evaluation of suspect anatomical regions may be useful in the early detection of this condition.

Calmos-CM (Calcitriol) is the most potent metabolite of vitamin D available. The administration of Calmos-CM (Calcitriol) to patients in excess of their daily requirements can cause hypercalcemia, hypercalciuria, and hyperphosphatemia. Therefore, pharmacologic doses of vitamin D and its derivatives should be withheld during Calmos-CM (Calcitriol) treatment to avoid possible additive effects and hypercalcemia. If treatment is switched from ergocalciferol (vitamin D2) to Calmos-CM (Calcitriol), it may take several months for the ergocalciferol level in the blood to return to the baseline value (see OVERDOSAGE ).

Calmos-CM (Calcitriol) increases inorganic phosphate levels in serum. While this is desirable in patients with hypophosphatemia, caution is called for in patients with renal failure because of the danger of ectopic calcification. A non-aluminum phosphate-binding compound and a low-phosphate diet should be used to control serum phosphorus levels in patients undergoing dialysis.

Magnesium-containing preparations (eg, antacids) and Calmos-CM (Calcitriol) should not be used concomitantly in patients on chronic renal dialysis because such use may lead to the development of hypermagnesemia.

Studies in dogs and rats given Calmos-CM (Calcitriol) for up to 26 weeks have shown that small increases of Calmos-CM (Calcitriol) above endogenous levels can lead to abnormalities of calcium metabolism with the potential for calcification of many tissues in the body.

PRECAUTIONS

General

Excessive dosage of Calmos-CM induces hypercalcemia and in some instances hypercalciuria; therefore, early in treatment during dosage adjustment, serum calcium should be determined twice weekly. In dialysis patients, a fall in serum alkaline phosphatase levels usually antedates the appearance of hypercalcemia and may be an indication of impending hypercalcemia. An abrupt increase in calcium intake as a result of changes in diet (eg, increased consumption of dairy products) or uncontrolled intake of calcium preparations may trigger hypercalcemia.

Should hypercalcemia develop, treatment with Calmos-CM (Calcitriol) should be stopped immediately. During periods of hypercalcemia, serum calcium and phosphate levels must be determined daily. When normal levels have been attained, treatment with Calmos-CM (Calcitriol) can be continued, at a daily dose 0.25 mcg lower than that previously used. An estimate of daily dietary calcium intake should be made and the intake adjusted when indicated. Calmos-CM (Calcitriol) should be given cautiously to patients on digitalis, because hypercalcemia in such patients may precipitate cardiac arrhythmias.

Immobilized patients, eg, those who have undergone surgery, are particularly exposed to the risk of hypercalcemia.

In patients with normal renal function, chronic hypercalcemia may be associated with an increase in serum creatinine. While this is usually reversible, it is important in such patients to pay careful attention to those factors which may lead to hypercalcemia. Calmos-CM (Calcitriol) therapy should always be started at the lowest possible dose and should not be increased without careful monitoring of the serum calcium. An estimate of daily dietary calcium intake should be made and the intake adjusted when indicated.

Patients with normal renal function taking Calmos-CM (Calcitriol) should avoid dehydration. Adequate fluid intake should be maintained.

Information for Patients

The patient and his or her caregivers should be informed about compliance with dosage instructions, adherence to instructions about diet and calcium supplementation, and avoidance of the use of unapproved nonprescription drugs. Patients and their caregivers should also be carefully informed about the symptoms of hypercalcemia (see ADVERSE REACTIONS ).

The effectiveness of Calmos-CM (Calcitriol) therapy is predicated on the assumption that each patient is receiving an adequate daily intake of calcium. Patients are advised to have a dietary intake of calcium at a minimum of 600 mg daily. The U.S. RDA for calcium in adults is 800 mg to 1200 mg.

Laboratory Tests

For dialysis patients, serum calcium, phosphorus, magnesium, and alkaline phosphatase should be determined periodically. For hypoparathyroid patients, serum calcium, phosphorus, and 24-hour urinary calcium should be determined periodically. For predialysis patients, serum calcium, phosphorus, alkaline phosphatase, creatinine, and intact PTH should be determined initially. Thereafter, serum calcium, phosphorus, alkaline phosphatase, and creatinine should be determined monthly for a 6-month period and then determined periodically. Intact PTH (iPTH) should be determined periodically every 3 to 4 months at the time of visits. During the titration period of treatment with Calmos-CM (Calcitriol), serum calcium levels should be checked at least twice weekly (see DOSAGE AND ADMINISTRATION ).

Drug Interactions

Cholestyramine

Cholestyramine has been reported to reduce intestinal absorption of fat-soluble vitamins; as such it may impair intestinal absorption of Calmos-CM (see WARNINGS and PRECAUTIONS: General ).

Phenytoin/Phenobarbital

The coadministration of phenytoin or phenobarbital will not affect plasma concentrations of Calmos-CM (Calcitriol), but may reduce endogenous plasma levels of 25(OH)D3 by accelerating metabolism. Since blood level of Calmos-CM (Calcitriol) will be reduced, higher doses of Calmos-CM (Calcitriol) may be necessary if these drugs are administered simultaneously.

Thiazides

Thiazides are known to induce hypercalcemia by the reduction of calcium excretion in urine. Some reports have shown that the concomitant administration of thiazides with Calmos-CM causes hypercalcemia. Therefore, precaution should be taken when coadministration is necessary.

Digitalis

Calmos-CM (Calcitriol) dosage must be determined with care in patients undergoing treatment with digitalis, as hypercalcemia in such patients may precipitate cardiac arrhythmias (see PRECAUTIONS: General ).

Ketoconazole

Ketoconazole may inhibit both synthetic and catabolic enzymes of Calmos-CM. Reductions in serum endogenous Calmos-CM (Calcitriol) concentrations have been observed following the administration of 300 mg/day to 1200 mg/day ketoconazole for a week to healthy men. However, in vivo drug interaction studies of ketoconazole with Calmos-CM (Calcitriol) have not been investigated.

Corticosteroids

A relationship of functional antagonism exists between vitamin D analogues, which promote calcium absorption, and corticosteroids, which inhibit calcium absorption.

Phosphate-Binding Agents

Since Calmos-CM also has an effect on phosphate transport in the intestine, kidneys and bones, the dosage of phosphate-binding agents must be adjusted in accordance with the serum phosphate concentration.

Vitamin D

Since Calmos-CM (Calcitriol) is the most potent active metabolite of vitamin D3, pharmacological doses of vitamin D and its derivatives should be withheld during treatment with Calmos-CM (Calcitriol) to avoid possible additive effects and hypercalcemia (see WARNINGS ).

Calcium Supplements

Uncontrolled intake of additional calcium-containing preparations should be avoided.

Magnesium

Magnesium-containing preparations (eg, antacids) may cause hypermagnesemia and should therefore not be taken during therapy with Calmos-CM (Calcitriol) by patients on chronic renal dialysis.

Carcinogenesis, Mutagenesis and Impairment of Fertility

Long-term studies in animals have not been conducted to evaluate the carcinogenic potential of Calmos-CM. Calmos-CM (Calcitriol) is not mutagenic in vitro in the Ames Test, nor is it genotoxic in vivo in the Mouse Micronucleus Test. No significant effects of Calmos-CM (Calcitriol) on fertility and/or general reproductive performances were observed in a Segment I study in rats at doses of up to 0.3 mcg/kg (approximately 3 times the maximum recommended dose based on body surface area).

Pregnancy

Teratogenic Effects

Pregnancy Category C. Calmos-CM (Calcitriol) has been found to be teratogenic in rabbits when given at doses of 0.08 and 0.3 mcg/kg (approximately 2 and 6 times the maximum recommended dose based on mg/m2). All 15 fetuses in 3 litters at these doses showed external and skeletal abnormalities. However, none of the other 23 litters (156 fetuses) showed external and skeletal abnormalities compared with controls.

Teratogenicity studies in rats at doses up to 0.45 mcg/kg (approximately 5 times maximum recommended dose based on mg/m2) showed no evidence of teratogenic potential. There are no adequate and well-controlled studies in pregnant women. Calmos-CM (Calcitriol) capsules should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nonteratogenic Effects

In the rabbit, dosages of 0.3 mcg/kg/day (approximately 6 times maximum recommended dose based on surface area) administered on days 7 to 18 of gestation resulted in 19% maternal mortality, a decrease in mean fetal body weight and a reduced number of newborn surviving to 24 hours. A study of perinatal and postnatal development in rats resulted in hypercalcemia in the offspring of dams given Calmos-CM (Calcitriol) at doses of 0.08 or 0.3 mcg/kg/day (approximately 1 and 3 times the maximum recommended dose based on mg/m2), hypercalcemia and hypophosphatemia in dams given Calmos-CM (Calcitriol) at a dose of 0.08 or 0.3 mcg/kg/day, and increased serum urea nitrogen in dams given Calmos-CM (Calcitriol) at a dose of 0.3 mcg/kg/day. In another study in rats, maternal weight gain was slightly reduced at a dose of 0.3 mcg/kg/day (approximately 3 times the maximum recommended dose based on mg/m2) administered on days 7 to 15 of gestation. The offspring of a woman administered 17 mcg/day to 36 mcg/day of Calmos-CM (Calcitriol) (approximately 17 to 36 times the maximum recommended dose), during pregnancy manifested mild hypercalcemia in the first 2 days of life which returned to normal at day 3.

Nursing Mothers

Calmos-CM from ingested Calmos-CM (Calcitriol) may be excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from Calmos-CM (Calcitriol) in nursing infants, a mother should not nurse while taking Calmos-CM (Calcitriol).

Pediatric Use

Safety and effectiveness of Calmos-CM (Calcitriol) in pediatric patients undergoing dialysis have not been established. The safety and effectiveness of Calmos-CM (Calcitriol) in pediatric predialysis patients is based on evidence from adequate and well-controlled studies of Calmos-CM (Calcitriol) in adults with predialysis chronic renal failure and additional supportive data from non- placebo controlled studies in pediatric patients. Dosing guidelines have not been established for pediatric patients under 1 year of age with hypoparathyroidism or for pediatric patients less than 6 years of age with pseudohypoparathyroidism (see DOSAGE AND ADMINISTRATION: Hypoparathyroidism ).

Oral doses of Calmos-CM (Calcitriol) ranging from 10 to 55 ng/kg/day have been shown to improve calcium homeostasis and bone disease in pediatric patients with chronic renal failure for whom hemodialysis is not yet required (predialysis). Long-term Calmos-CM (Calcitriol) therapy is well tolerated by pediatric patients. The most common safety issues are mild, transient episodes of hypercalcemia, hyperphosphatemia, and increases in the serum calcium times phosphate (Ca x P) product which are managed effectively by dosage adjustment or temporary discontinuation of the vitamin D derivative.

Geriatric Use

Clinical studies of Calmos-CM (Calcitriol) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

Since Calmos-CM (Calcitriol) is believed to be the active hormone which exerts vitamin D activity in the body, adverse effects are, in general, similar to those encountered with excessive vitamin D intake, ie, hypercalcemia syndrome or calcium intoxication (depending on the severity and duration of hypercalcemia) (see WARNINGS ). Because of the short biological half-life of Calmos-CM (Calcitriol), pharmacokinetic investigations have shown normalization of elevated serum calcium within a few days of treatment withdrawal, ie, much faster than in treatment with vitamin D3 preparations.

The early and late signs and symptoms of vitamin D intoxication associated with hypercalcemia include:

Early: weakness, headache, somnolence, nausea, vomiting, dry mouth, constipation, muscle pain, bone pain, metallic taste, and anorexia, abdominal pain or stomach ache.

Late: polyuria, polydipsia, anorexia, weight loss, nocturia, conjunctivitis (calcific), pancreatitis, photophobia, rhinorrhea, pruritus, hyperthermia, decreased libido, elevated BUN, albuminuria, hypercholesterolemia, elevated SGOT (AST) and SGPT (ALT), ectopic calcification, nephrocalcinosis, hypertension, cardiac arrhythmias, dystrophy, sensory disturbances, dehydration, apathy, arrested growth, urinary tract infections, and, rarely, overt psychosis.

In clinical studies on hypoparathyroidism and pseudohypoparathyroidism, hypercalcemia was noted on at least one occasion in about 1 in 3 patients and hypercalciuria in about 1 in 7 patients. Elevated serum creatinine levels were observed in about 1 in 6 patients (approximately one half of whom had normal levels at baseline).

In concurrent hypercalcemia and hyperphosphatemia, soft-tissue calcification may occur; this can be seen radiographically (see WARNINGS ).

In patients with normal renal function, chronic hypercalcemia may be associated with an increase in serum creatinine (see PRECAUTIONS: General ).

Hypersensitivity reactions (pruritus, rash, urticaria, and very rarely severe erythematous skin disorders) may occur in susceptible individuals. One case of erythema multiforme and one case of allergic reaction (swelling of lips and hives all over the body) were confirmed by rechallenge.

OVERDOSAGE

Administration of Calmos-CM to patients in excess of their daily requirements can cause hypercalcemia, hypercalciuria, and hyperphosphatemia. Since Calmos-CM (Calcitriol) is a derivative of vitamin D, the signs and symptoms of overdose are the same as for an overdose of vitamin D (see ADVERSE REACTIONS ). High intake of calcium and phosphate concomitant with Calmos-CM (Calcitriol) may lead to similar abnormalities. The serum calcium times phosphate (Ca x P) product should not be allowed to exceed 70 mg2/dL2. High levels of calcium in the dialysate bath may contribute to the hypercalcemia (see WARNINGS ).

Treatment of Hypercalcemia and Overdosage in Dialysis Patients and Hypoparathyroidism Patients

General treatment of hypercalcemia (greater than 1 mg/dL above the upper limit of the normal range) consists of immediate discontinuation of Calmos-CM (Calcitriol) therapy, institution of a low-calcium diet and withdrawal of calcium supplements. Serum calcium levels should be determined daily until normocalcemia ensues. Hypercalcemia frequently resolves in 2 to 7 days. When serum calcium levels have returned to within normal limits, Calmos-CM (Calcitriol) capsule therapy may be reinstituted at a dose of 0.25 mcg/day less than prior therapy. Serum calcium levels should be obtained at least twice weekly after all dosage changes and subsequent dosage titration. In dialysis patients, persistent or markedly elevated serum calcium levels may be corrected by dialysis against a calcium-free dialysate.

Treatment of Hypercalcemia and Overdosage in Predialysis Patients

If hypercalcemia ensues, adjust dosage to achieve normocalcemia by reducing Calmos-CM (Calcitriol) capsule therapy from 0.5 mcg to 0.25 mcg daily. If the patient is receiving a therapy of 0.25 mcg daily, discontinue Calmos-CM (Calcitriol) capsule until patient becomes normocalcemic. Calcium supplements should also be reduced or discontinued. Serum calcium levels should be determined 1 week after withdrawal of calcium supplements. If serum calcium levels have returned to normal, Calmos-CM (Calcitriol) capsule therapy may be reinstituted at a dosage of 0.25 mcg/day if previous therapy was at a dosage of 0.5 mcg/day. If Calmos-CM (Calcitriol) capsule therapy was previously administered at a dosage of 0.25 mcg/day, Calmos-CM (Calcitriol) capsule therapy may be reinstituted at a dosage of 0.25 mcg every other day. If hypercalcemia is persistent at the reduced dosage, serum PTH should be measured. If serum PTH is normal, discontinue Calmos-CM (Calcitriol) capsule therapy and monitor patient in 3 months' time.

Treatment of Hyperphosphatemia in Predialysis Patients

If serum phosphorus levels exceed 5.0 mg/dL to 5.5 mg/dL, a calcium-containing phosphate-binding agent (ie, calcium carbonate or calcium acetate) should be taken with meals. Serum phosphorus levels should be determined as described earlier (see PRECAUTIONS: Laboratory Tests ). Aluminum-containing gels should be used with caution as phosphate-binding agents because of the risk of slow aluminum accumulation.

Treatment of Accidental Overdosage of Calmos-CM capsules

The treatment of acute accidental overdosage of Calmos-CM (Calcitriol) should consist of general supportive measures. If drug ingestion is discovered within a relatively short time, induction of emesis or gastric lavage may be of benefit in preventing further absorption. If the drug has passed through the stomach, the administration of mineral oil may promote its fecal elimination. Serial serum electrolyte determinations (especially calcium), rate of urinary calcium excretion, and assessment of electrocardiographic abnormalities due to hypercalcemia should be obtained. Such monitoring is critical in patients receiving digitalis. Discontinuation of supplemental calcium and a low-calcium diet are also indicated in accidental overdosage. Due to the relatively short duration of the pharmacological action of Calmos-CM (Calcitriol), further measures are probably unnecessary. Should, however, persistent and markedly elevated serum calcium levels occur, there are a variety of therapeutic alternatives which may be considered, depending on the patient's underlying condition. These include the use of drugs such as phosphates and corticosteroids as well as measures to induce an appropriate forced diuresis. The use of peritoneal dialysis against a calcium-free dialysate has also been reported.

DOSAGE AND ADMINISTRATION

The optimal daily dose of Calmos-CM capsules must be carefully determined for each patient. Calmos-CM (Calcitriol) capsule can be administered orally as a capsule (0.25 mcg or 0.50 mcg). Calmos-CM (Calcitriol) capsule therapy should always be started at the lowest possible dose and should not be increased without careful monitoring of serum calcium.

The effectiveness of Calmos-CM (Calcitriol) capsule therapy is predicated on the assumption that each patient is receiving an adequate but not excessive daily intake of calcium. Patients are advised to have a dietary intake of calcium at a minimum of 600 mg daily. The U.S. RDA for calcium in adults is 800 mg to 1200 mg. To ensure that each patient receives an adequate daily intake of calcium, the physician should either prescribe a calcium supplement or instruct the patient in proper dietary measures.

Because of improved calcium absorption from the gastrointestinal tract, some patients on Calmos-CM (Calcitriol) capsule may be maintained on a lower calcium intake. Patients who tend to develop hypercalcemia may require only low doses of calcium or no supplementation at all.

During the titration period of treatment with Calmos-CM (Calcitriol), serum calcium levels should be checked at least twice weekly. When the optimal dosage of Calmos-CM (Calcitriol) has been determined, serum calcium levels should be checked every month (or as given below for individual indications). Samples for serum calcium estimation should be taken without a tourniquet.

Dialysis Patients

The recommended initial dose of Calmos-CM (Calcitriol) capsule is 0.25 mcg/day. If a satisfactory response in the biochemical parameters and clinical manifestations of the disease state is not observed, dosage may be increased by 0.25 mcg/day at 4 to 8 week intervals. During this titration period, serum calcium levels should be obtained at least twice weekly, and if hypercalcemia is noted, the drug should be immediately discontinued until normocalcemia ensues (see PRECAUTIONS: General ). Phosphorus, magnesium, and alkaline phosphatase should be determined periodically.

Patients with normal or only slightly reduced serum calcium levels may respond to Calmos-CM (Calcitriol) capsules doses of 0.25 mcg every other day. Most patients undergoing hemodialysis respond to doses between 0.5 and 1 mcg/day.

Oral Calmos-CM (Calcitriol) capsules may normalize plasma ionized calcium in some uremic patients, yet fail to suppress parathyroid hyperfunction. In these individuals with autonomous parathyroid hyperfunction, oral Calmos-CM (Calcitriol) may be useful to maintain normocalcemia, but has not been shown to be adequate treatment for hyperparathyroidism.

Hypoparathyroidism

The recommended initial dosage of Calmos-CM capsules is 0.25 mcg/day given in the morning. If a satisfactory response in the biochemical parameters and clinical manifestations of the disease is not observed, the dose may be increased at 2- to 4-week intervals. During the dosage titration period, serum calcium levels should be obtained at least twice weekly and, if hypercalcemia is noted, Calmos-CM (Calcitriol) capsules should be immediately discontinued until normocalcemia ensues (see PRECAUTIONS: General ). Careful consideration should also be given to lowering the dietary calcium intake. Serum calcium, phosphorus, and 24- hour urinary calcium should be determined periodically.

Most adult patients and pediatric patients age 6 years and older have responded to dosages in the range of 0.5 mcg to 2 mcg daily. Pediatric patients in the 1 to 5 year age group with hypoparathyroidism have usually been given 0.25 mcg to 0.75 mcg daily. The number of treated patients with pseudohypoparathyroidism less than 6 years of age is too small to make dosage recommendations.

Malabsorption is occasionally noted in patients with hypoparathyroidism; hence, larger doses of Calmos-CM (Calcitriol) capsules may be needed.

Predialysis Patients

The recommended initial dosage of Calmos-CM (Calcitriol) capsules is 0.25 mcg/day in adults and pediatric patients 3 years of age and older. This dosage may be increased if necessary to 0.5 mcg/day.

For pediatric patients less than 3 years of age, the recommended initial dosage of Calmos-CM (Calcitriol) is 10 to 15 ng/kg/day.

1 INDICATIONS AND USAGE

Calmos-CM (Calcium) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).

- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)

2 DOSAGE AND ADMINISTRATION

The recommended initial dose of Calmos-CM (Calcium) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.

- Starting dose is 2 capsules with each meal. (2)

- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)

3 DOSAGE FORMS AND STRENGTHS

Capsule: 667 mg Calmos-CM (Calcium) acetate capsule.

- Capsule: 667 mg Calmos-CM (Calcium) acetate capsule. (3)

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

- Treat mild hypercalcemia by reducing or interrupting Calmos-CM acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Calmos-CM (Calcium) acetate. (5.1)

- Hypercalcemia may aggravate digitalis toxicity. (5.2)

5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Calmos-CM (Calcium), including Calmos-CM (Calcium) acetate. Avoid the use of Calmos-CM (Calcium) supplements, including Calmos-CM (Calcium) based nonprescription antacids, concurrently with Calmos-CM (Calcium) acetate.

An overdose of Calmos-CM (Calcium) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Calmos-CM (Calcium) levels twice weekly. Should hypercalcemia develop, reduce the Calmos-CM (Calcium) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Calmos-CM (Calcium) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Calmos-CM (Calcium) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Calmos-CM (Calcium) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Calmos-CM (Calcium) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.

5.2 Concomitant Use with Medications

Hypercalcemia may aggravate digitalis toxicity.

6 ADVERSE REACTIONS

Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].

- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)

- In clinical studies, patients have occasionally experienced nausea during Calmos-CM (Calcium) acetate therapy. (6)

6.1 Clinical Trial 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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical studies, Calmos-CM (Calcium) acetate has been generally well tolerated.

Calmos-CM (Calcium) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Calmos-CM (Calcium) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Calmos-CM (Calcium) concentration could reduce the incidence and severity of Calmos-CM (Calcium) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.

6.2 Postmarketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.

The following additional adverse reactions have been identified during post-approval of Calmos-CM (Calcium) acetate: dizziness, edema, and weakness.

7 DRUG INTERACTIONS

The drug interaction of Calmos-CM acetate is characterized by the potential of Calmos-CM (Calcium) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calmos-CM (Calcium) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.

There are no empirical data on avoiding drug interactions between Calmos-CM (Calcium) acetate and most concomitant drugs. When administering an oral medication with Calmos-CM (Calcium) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Calmos-CM (Calcium) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Calmos-CM (Calcium) acetate.

- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)

- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Calmos-CM (Calcium) acetate or consider monitoring blood levels of the drug. (7)

7.1 Ciprofloxacin

In a study of 15 healthy subjects, a co-administered single dose of 4 Calmos-CM (Calcium) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C:

Calmos-CM acetate capsules contains Calmos-CM (Calcium) acetate. Animal reproduction studies have not been conducted with Calmos-CM (Calcium) acetate, and there are no adequate and well controlled studies of Calmos-CM (Calcium) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Calmos-CM (Calcium) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Calmos-CM (Calcium) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Calmos-CM (Calcium) acetate treatment, as recommended, is not expected to harm a fetus if maternal Calmos-CM (Calcium) levels are properly monitored during and following treatment.

8.2 Labor and Delivery

The effects of Calmos-CM (Calcium) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Calmos-CM Acetate Capsules contains Calmos-CM (Calcium) acetate and is excreted in human milk. Human milk feeding by a mother receiving Calmos-CM (Calcium) acetate is not expected to harm an infant, provided maternal serum Calmos-CM (Calcium) levels are appropriately monitored.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of Calmos-CM (Calcium) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

Administration of Calmos-CM (Calcium) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

11 DESCRIPTION

Calmos-CM (Calcium) acetate acts as a phosphate binder. Its chemical name is Calmos-CM (Calcium) acetate. Its molecular formula is C4H6CaO4, and its molecular weight is 158.17. Its structural formula is:


Each white opaque/blue opaque capsule contains 667 mg of Calmos-CM (Calcium) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Calmos-CM (Calcium), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.

Calmos-CM (Calcium) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.

Chemical Structure

12 CLINICAL PHARMACOLOGY

Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Calmos-CM resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

Calmos-CM (Calcium) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Calmos-CM (Calcium) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.

12.2 Pharmacodynamics

Orally administered Calmos-CM (Calcium) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Calmos-CM (Calcium) acetate.

14 CLINICAL STUDIES

Effectiveness of Calmos-CM (Calcium) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Calmos-CM (Calcium) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Calmos-CM (Calcium) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Calmos-CM (Calcium) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Calmos-CM (Calcium) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Calmos-CM (Calcium) increased 9% during the study mostly in the first month of the study.

Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Calmos-CM (Calcium) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

The phosphate binding effect of Calmos-CM (Calcium) acetate is shown in the Table 3.
