Calcium (Ossein Complex Hydroxyapatite):


1 INDICATIONS AND USAGE

Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate capsule.

- Capsule: 667 mg Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate capsule. (3)

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

- Treat mild hypercalcemia by reducing or interrupting Ossopan ) acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)), including Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate. Avoid the use of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) supplements, including Ossopan (Calcium (Ossein Complex Hydroxyapatite)) based nonprescription antacids, concurrently with Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate.

An overdose of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Ossopan (Calcium (Ossein Complex Hydroxyapatite)) levels twice weekly. Should hypercalcemia develop, reduce the Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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.

7 DRUG INTERACTIONS

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

There are no empirical data on avoiding drug interactions between Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate and most concomitant drugs. When administering an oral medication with Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C:

Ossopan ) acetate capsules contains Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate. Animal reproduction studies have not been conducted with Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate, and there are no adequate and well controlled studies of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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. Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate treatment, as recommended, is not expected to harm a fetus if maternal Ossopan (Calcium (Ossein Complex Hydroxyapatite)) levels are properly monitored during and following treatment.

8.2 Labor and Delivery

The effects of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Ossopan ) Acetate Capsules contains Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate and is excreted in human milk. Human milk feeding by a mother receiving Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate is not expected to harm an infant, provided maternal serum Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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.

Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

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

12.2 Pharmacodynamics

Orally administered Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate.

14 CLINICAL STUDIES

Effectiveness of Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) 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 Ossopan (Calcium (Ossein Complex Hydroxyapatite)) acetate is shown in the Table 3.
