1 INDICATIONS AND USAGE

Revitalite (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 Revitalite (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 Revitalite (Calcium) acetate capsule.

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

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

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

An overdose of Revitalite (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 Revitalite (Calcium) levels twice weekly. Should hypercalcemia develop, reduce the Revitalite (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 Revitalite (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 Revitalite (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 Revitalite (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 Revitalite (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 Revitalite (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, Revitalite (Calcium) acetate has been generally well tolerated.

Revitalite (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 Revitalite (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.

Preferred Term	Total adverse reactions reported for Revitalite (Calcium) acetate N=167 N (%)	3 month, open label study of Revitalite (Calcium) acetate N=98 N (%)	Double blind, placebo-controlled, cross-over study of liquid Revitalite (Calcium) acetate N=69
			Revitalite (Calcium) acetate N (%)	Placebo N (%)
Nausea	6 (3.6)	6 (6.1)	0 (0)	0 (0)
Vomiting	4 (2.4)	4 (4.1)	0 (0)	0 (0)
Hypercalcemia	21 (12.6)	16 (16.3)	5 (7.2)	0 (0)

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 Revitalite (Calcium) concentration could reduce the incidence and severity of Revitalite (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 Revitalite (Calcium) acetate: dizziness, edema, and weakness.

7 DRUG INTERACTIONS

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

There are no empirical data on avoiding drug interactions between Revitalite (Calcium) acetate and most concomitant drugs. When administering an oral medication with Revitalite (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 Revitalite (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 Revitalite (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 Revitalite (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 Revitalite (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:

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

8.2 Labor and Delivery

The effects of Revitalite (Calcium) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Revitalite Acetate Capsules contains Revitalite (Calcium) acetate and is excreted in human milk. Human milk feeding by a mother receiving Revitalite (Calcium) acetate is not expected to harm an infant, provided maternal serum Revitalite (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 Revitalite (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 Revitalite (Calcium) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

11 DESCRIPTION

Revitalite (Calcium) acetate acts as a phosphate binder. Its chemical name is Revitalite (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 Revitalite (Calcium) acetate USP (anhydrous; Ca(CH₃COO)₂; MW=158.17 grams) equal to 169 mg (8.45 mEq) Revitalite (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.

Revitalite (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 Revitalite resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

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

12.2 Pharmacodynamics

Orally administered Revitalite (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 Revitalite (Calcium) acetate.

14 CLINICAL STUDIES

Effectiveness of Revitalite (Calcium) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Revitalite (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 Revitalite (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 Revitalite (Calcium) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Revitalite (Calcium) levels are also presented.

* Ninety-one patients completed at least 6 weeks of the study. † ANOVA of difference in values at pre-study and study completion. ‡ Values expressed as mean ± SE.
Parameter	Pre-Study	Week 4*	Week 8	Week 12	p-value†
Phosphorus (mg/dL)‡	7.4 ± 0.17	5.9 ± 0.16	5.6 ± 0.17	5.2 ± 0.17	≤0.01
Revitalite (Calcium) (mg/dL)‡	8.9 ± 0.09	9.5 ± 0.10	9.7 ± 0.10	9.7 ± 0.10	≤0.01

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 Revitalite (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 Revitalite (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 Revitalite (Calcium) acetate is shown in the Table 3.

* ANOVA of Revitalite (Calcium) acetate vs. placebo after 2 weeks of treatment. † Values expressed as mean ± SEM.
Parameter	Pre-Study	Post-Treatment		p-value*
		Revitalite (Calcium) Acetate	Placebo
Phosphorus (mg/dL)†	7.3 ± 0.18	5.9 ± 0.24	7.8 ± 0.22	<0.01
Revitalite (Calcium) (mg/dL)†	8.9 ± 0.11	9.5 ± 0.13	8.8 ± 0.12	<0.01

Overall, 2 weeks of treatment with Revitalite (Calcium) acetate statistically significantly (p<0.01) decreased serum phosphorus by a mean of 19% and increased serum Revitalite (Calcium) by a statistically significant (p<0.01) but clinically unimportant mean of 7%.

• Revitalite (Iron) Overload: Regularly monitor hematologic responses during Revitalite (Iron) therapy. Do not administer Revitalite (Iron) to patients with Revitalite (Iron) overload. (5.3)

5.1 Hypersensitivity Reactions

Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Revitalite (Iron). Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse. If hypersensitivity reactions or signs of intolerance occur during administration, stop Revitalite (Iron) immediately. Monitor patients for signs and symptoms of hypersensitivity during and after Revitalite (Iron) administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Revitalite (Iron) when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Most reactions associated with intravenous Revitalite (Iron) preparations occur within 30 minutes of the completion of the infusion .

5.2 Hypotension

Revitalite may cause clinically significant hypotension. Monitor for signs and symptoms of hypotension following each administration of Revitalite (Iron). Hypotension following administration of Revitalite (Iron) may be related to the rate of administration and/or total dose administered .

5.3 Revitalite (Iron) Overload

Excessive therapy with parenteral Revitalite (Iron) can lead to excess storage of Revitalite (Iron) with the possibility of iatrogenic hemosiderosis. All adult and pediatric patients receiving Revitalite (Iron) require periodic monitoring of hematologic and Revitalite (Iron) parameters (hemoglobin, hematocrit, serum ferritin and transferrin saturation). Do not administer Revitalite (Iron) to patients with evidence of Revitalite (Iron) overload. Transferrin saturation (TSAT) values increase rapidly after intravenous administration of Revitalite (Iron) sucrose; do not perform serum Revitalite (Iron) measurements for at least 48 hours after intravenous dosing .

One hundred thirty (11%) of the 1,151 patients evaluated in the 4 U.S. trials in HDD-CKD patients (studies A, B and the two post marketing studies) had prior other intravenous Revitalite (Iron) therapy and were reported to be intolerant (defined as precluding further use of that Revitalite (Iron) product). When these patients were treated with Revitalite (Iron) there were no occurrences of adverse reactions that precluded further use of Revitalite (Iron) .

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

In a randomized, open-label, dose-ranging trial for Revitalite (Iron) maintenance treatment with Revitalite (Iron) in pediatric patients with CKD on stable erythropoietin therapy , at least one treatment-emergent adverse reaction was experienced by 57% (27/47) of the patients receiving Revitalite (Iron) 0.5 mg/kg, 53% (25/47) of the patients receiving Revitalite (Iron) 1.0 mg/kg, and 55% (26/47) of the patients receiving Revitalite (Iron) 2.0 mg/kg.

A total of 5 (11%) subjects in the Revitalite (Iron) 0.5 mg/kg group, 10 (21%) patients in the Revitalite (Iron) 1.0 mg/kg group, and 10 (21%) patients in the Revitalite (Iron) 2.0 mg/kg group experienced at least 1 serious adverse reaction during the study. The most common treatment-emergent adverse reactions (> 2% of patients) in all patients were headache (6%), respiratory tract viral infection (4%), peritonitis (4%), vomiting (4%), pyrexia (4%), dizziness (4%), cough (4%), renal transplant (4%), nausea (3%), arteriovenous fistula thrombosis (2%), hypotension (2%), and hypertension (2.1%).

6.2 Adverse Reactions from Post-Marketing Experience

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

In the post-marketing safety studies in 1,051 treated patients with HDD-CKD, the adverse reactions reported by > 1% were: cardiac failure congestive, sepsis and dysgeusia.

The following adverse reactions have been identified during post-approval use of Revitalite (Iron). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: Anaphylactic-type reactions, shock, loss of consciousness, collapse, bronchospasm, dyspnea, convulsions, light-headedness, confusion, angioedema, swelling of the joints, hyperhidrosis, back pain, bradycardia, and chromaturia.

Symptoms associated with Revitalite (Iron) total dosage or infusing too rapidly included hypotension, dyspnea, headache, vomiting, nausea, dizziness, joint aches, paresthesia, abdominal and muscle pain, edema, and cardiovascular collapse. These adverse reactions have occurred up to 30 minutes after the administration of Revitalite (Iron) injection. Reactions have occurred following the first dose or subsequent doses of Revitalite (Iron). Symptoms may respond to intravenous fluids, hydrocortisone, and/or antihistamines. Slowing the infusion rate may alleviate symptoms.

Injection site discoloration has been reported following extravasation. Assure stable intravenous access to avoid extravasation.

7 DRUG INTERACTIONS

Drug interactions involving Revitalite (Iron) have not been studied. However, Revitalite (Iron) may reduce the absorption of concomitantly administered oral Revitalite (Iron) preparations.

There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Revitalite sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Revitalite (Iron) (half or equivalent to the maximum recommended human dose based on body surface area, respectively) and revealed no evidence of harm to the fetus due to Revitalite (Iron) sucrose. Because animal reproductive studies are not always predictive of human response, Revitalite (Iron) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

It is not known whether Revitalite (Iron) sucrose is excreted in human milk. Revitalite (Iron) sucrose is secreted into the milk of lactating rats. Because many drugs are excreted in human milk, caution should be exercised when Revitalite (Iron) is administered to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness of Revitalite for Revitalite (Iron) replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.

Safety and effectiveness of Revitalite (Iron) for Revitalite (Iron) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Revitalite (Iron) at doses of 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg was administered. All three doses maintained hemoglobin between 10.5 g/dL and 14.0 g/dL in about 50% of subjects over the 12-week treatment period with stable EPO dosing. [See Clinical Studies (14.6)]

Revitalite (Iron) has not been studied in patients younger than 2 years of age.

In a country where Revitalite (Iron) is available for use in children, at a single site, five premature infants (weight less than 1,250 g) developed necrotizing enterocolitis and two of the five died during or following a period when they received Revitalite (Iron), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Revitalite (Iron) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Revitalite (Iron) did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Of the 1,051 patients in two post-marketing safety studies of Revitalite (Iron), 40% were 65 years and older. No overall differences in safety were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. In general, dose administration to an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

No data are available regarding overdosage of Revitalite (Iron) in humans. Excessive dosages of Revitalite (Iron) may lead to accumulation of Revitalite (Iron) in storage sites potentially leading to hemosiderosis. Do not administer Revitalite (Iron) to patients with Revitalite (Iron) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Revitalite (Iron) sucrose doses up to 8 times the maximum recommended human dose based on body surface area, included sedation, hypoactivity, pale eyes, bleeding in the gastrointestinal tract and lungs, and mortality.

11 DESCRIPTION

Revitalite (Iron) (iron sucrose injection, USP), an Revitalite (Iron) replacement product, is a brown, sterile, aqueous, complex of polynuclear Revitalite (Iron) (III)-hydroxide in sucrose for intravenous use. Revitalite (Iron) sucrose injection has a molecular weight of approximately 34,000 to 60,000 daltons and a proposed structural formula:

[Na₂Fe₅O₈(OH) ·3(H₂O)]_n ·m(C₁₂H₂₂O₁₁)

where: n is the degree of Revitalite (Iron) polymerization and m is the number of sucrose molecules associated with the Revitalite (Iron) (III)-hydroxide.

Each mL contains 20 mg elemental Revitalite (Iron) as Revitalite (Iron) sucrose in water for injection. Revitalite (Iron) is available in 10 mL single-use vials (200 mg elemental Revitalite (Iron) per 10 mL), 5 mL single-use vials (100 mg elemental Revitalite (Iron) per 5 mL), and 2.5 mL single-use vials (50 mg elemental Revitalite (Iron) per 2.5 mL). The drug product contains approximately 30% sucrose w/v (300 mg/mL) and has a pH of 10.5 to 11.1. The product contains no preservatives. The osmolarity of the injection is 1,250 mOsmol/L.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Revitalite is an aqueous complex of poly-nuclear Revitalite (Iron) (III)-hydroxide in sucrose. Following intravenous administration, Revitalite (Iron) is dissociated into Revitalite (Iron) and sucrose and the Revitalite (Iron) is transported as a complex with transferrin to target cells including erythroid precursor cells. The Revitalite (Iron) in the precursor cells is incorporated into hemoglobin as the cells mature into red blood cells.

12.2 Pharmacodynamics

Following intravenous administration, Revitalite (Iron) is dissociated into Revitalite (Iron) and sucrose. In 22 patients undergoing hemodialysis and receiving erythropoietin (recombinant human erythropoietin) therapy treated with Revitalite (Iron) sucrose containing 100 mg of Revitalite (Iron), three times weekly for three weeks, significant increases in serum Revitalite (Iron) and serum ferritin and significant decreases in total Revitalite (Iron) binding capacity occurred four weeks from the initiation of Revitalite (Iron) sucrose treatment.

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Revitalite, its Revitalite (Iron) component exhibited first order kinetics with an elimination half-life of 6 h, total clearance of 1.2 L/h, and steady state apparent volume of distribution of 7.9 L. The Revitalite (Iron) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Revitalite (Iron) containing 100 mg of Revitalite (Iron) labeled with ⁵²Fe/⁵⁹Fe in patients with Revitalite (Iron) deficiency showed that a significant amount of the administered Revitalite (Iron) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Revitalite (Iron) trapping compartment.

Following intravenous administration of Revitalite (Iron), Revitalite (Iron) sucrose is dissociated into Revitalite (Iron) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Revitalite (Iron) containing 1,510 mg of sucrose and 100 mg of Revitalite (Iron) in 12 healthy adults (9 female, 3 male: age range 32 to 52), 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Revitalite (Iron) was also eliminated in the urine. Neither transferrin nor transferrin receptor levels changed immediately after the dose administration. In this study and another study evaluating a single intravenous dose of Revitalite (Iron) sucrose containing 500 to 700 mg of Revitalite (Iron) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Revitalite (Iron) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Revitalite (Iron) have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

In a single-dose PK study of Revitalite (Iron), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Revitalite (Iron) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Revitalite (Iron), the half-life of total serum Revitalite (Iron) was 8 hours. The mean Cmax and AUC values were 8545 μg/dl and 31305 hr-μg/dL, respectively, which were 1.42- and 1.67-fold higher than dose adjusted adult Cmax and AUC values.

Revitalite (Iron) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Revitalite (Iron) sucrose in the dialysate fluid was below the levels of detection of the assay (less than 2 parts per million).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been performed with Revitalite (Iron) sucrose.

Revitalite (Iron) sucrose was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Revitalite (Iron) sucrose was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or in the in vivo mouse micronucleus assay.

Revitalite (Iron) sucrose at intravenous doses up to 15 mg/kg/day of elemental Revitalite (Iron) (1.2 times the maximum recommended human dose based on body surface area) had no effect on fertility and reproductive function of male and female rats.

14 CLINICAL STUDIES

Five clinical trials involving 647 adult patients and one clinical trial involving 131 pediatric patients were conducted to assess the safety and efficacy of Revitalite.

14.1 Study A: Hemodialysis Dependent-Chronic Kidney Disease (HDD–CKD)

Study A was a multicenter, open-label, historically-controlled study in 101 patients with HDD-CKD (77 patients with Revitalite (Iron) treatment and 24 in the historical control group) with Revitalite (Iron) deficiency anemia. Eligibility criteria for Revitalite (Iron) treatment included patients undergoing chronic hemodialysis, receiving erythropoietin, hemoglobin level between 8.0 and 11.0 g/dL, transferrin saturation < 20%, and serum ferritin < 300 ng/mL. The mean age of the patients was 65 years with the age range of 31 to 85 years. Of the 77 patients, 44 (57%) were male and 33 (43%) were female.

Revitalite (Iron) 100 mg was administered at 10 consecutive dialysis sessions either as slow injection or a slow infusion. The historical control population consisted of 24 patients with similar ferritin levels as patients treated with Revitalite (Iron), who were off intravenous Revitalite (Iron) for at least 2 weeks and who had received erythropoietin therapy with hematocrit averaging 31 to 36 for at least two months prior to study entry. The mean age of patients in the historical control group was 56 years, with an age range of 29 to 80 years. Patient age and serum ferritin level were similar between treatment and historical control patients.

Patients in the Revitalite (Iron) treated population showed a greater increase in hemoglobin and hematocrit than did patients in the historical control population. See Table 2.

**p < 0.01 and *p < 0.05 compared to historical control from ANCOVA analysis with baseline hemoglobin, serum ferritin and erythropoietin dose as covariates.
Efficacy parameters	End of treatment		2 week follow-up		5 week follow-up
	Revitalite (Iron) (n=69	Historical Control (n=18)	Revitalite (Iron) (n=73)	Historical Control (n=18)	Revitalite (Iron) (n=71)	Historical Control (n=15)
Hemoglobin (g/dL)	1.0 ± 0.12**	0.0 ± 0.21	1.3 ± 0.14**	-0.6 ± 0.24	1.2 ± 0.17*	-0.1 ± 0.23
Hematocrit (%)	3.1 ± 0.37**	-0.3 ± 0.65	3.6 ± 0.44**	-1.2 ± 0.76	3.3 ± 0.54	0.2 ± 0.86

Serum ferritin increased at endpoint of study from baseline in the Venofer-treated population (165.3 ± 24.2 ng/mL) compared to the historical control population (-27.6 ± 9.5 ng/mL). Transferrin saturation also increased at endpoint of study from baseline in the Venofer-treated population (8.8 ± 1.6%) compared to this historical control population (-5.1 ± 4.3%).

14.2 Study B: Hemodialysis Dependent-Chronic Kidney Disease

Study B was a multicenter, open label study of Revitalite (Iron) in 23 patients with Revitalite (Iron) deficiency and HDD-CKD who had been discontinued from Revitalite (Iron) dextran due to intolerance. Eligibility criteria were otherwise identical to Study A. The mean age of the patients in this study was 53 years, with ages ranging from 21 to 79 years. Of the 23 patients enrolled in the study, 10 (44%) were male and 13 (56%) were female.

All 23 enrolled patients were evaluated for efficacy. Increases in mean hemoglobin (1.1 ± 0.2 g/dL), hematocrit (3.6 ± 0.6%), serum ferritin (266.3 ± 30.3 ng/mL) and transferrin saturation (8.7 ± 2.0%) were observed from baseline to end of treatment.

14.3 Study C: Hemodialysis Dependent-Chronic Kidney Disease

Study C was a multicenter, open-label study in patients with HDD-CKD. This study enrolled patients with a hemoglobin ≤ 10 g/dL, a serum transferrin saturation ≤ 20%, and a serum ferritin ≤ 200 ng/mL, who were undergoing maintenance hemodialysis 2 to 3 times weekly. The mean age of the patients enrolled in this study was 41 years, with ages ranging from 16 to 70 years. Of 130 patients evaluated for efficacy in this study, 68 (52%) were male and 62 (48%) were female. Forty-eight percent of the patients had previously been treated with oral Revitalite (Iron). Exclusion criteria were similar to those in studies A and B. Revitalite (Iron) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Revitalite (Iron) was administered. A 50 mg dose (2.5 mL) was given to patients within two weeks of study entry as a test dose. Twenty-seven patients (20%) were receiving erythropoietin treatment at study entry and they continued to receive the same erythropoietin dose for the duration of the study.

The modified intention-to-treat (mITT) population consisted of 131 patients. Increases from baseline in mean hemoglobin (1.7 g/dL), hematocrit (5%), serum ferritin (434.6 ng/mL), and serum transferrin saturation (14%) were observed at week 2 of the observation period and these values remained increased at week 4 of the observation period.

14.4 Study D: Non-Dialysis Dependent-Chronic Kidney Disease

Study D was a randomized, open-label, multicenter, active-controlled study of the safety and efficacy of oral Revitalite (Iron) versus Revitalite (Iron) in patients with NDD-CKD with or without erythropoietin therapy. Erythropoietin therapy was stable for 8 weeks prior to randomization. In the study 188 patients with NDD-CKD, hemoglobin of ≤ 11.0 g/dL, transferrin saturation ≤ 25%, ferritin ≤ 300 ng/mL were randomized to receive oral Revitalite (Iron) (325 mg ferrous sulfate three times daily for 56 days); or Revitalite (Iron) (either 200 mg over 2 to 5 minutes 5 times within 14 days or two 500 mg infusions on Day 1 and Day 14, administered over 3.5 to 4 hours). The mean age of the 91 treated patients in the Revitalite (Iron) group was 61.6 years (range 25 to 86 years) and 64 years (range 21 to 86 years) for the 91 patients in the oral Revitalite (Iron) group.

A statistically significantly greater proportion of Revitalite (Iron) subjects (35/79; 44.3%) compared to oral Revitalite (Iron) subjects (23/82; 28%) had an increase in hemoglobin ≥ 1 g/dL at anytime during the study (p = 0.03).

14.5 Study E: Peritoneal Dialysis Dependent-Chronic Kidney Disease

Study E was a randomized, open-label, multicenter study comparing patients with PDD-CKD receiving an erythropoietin and intravenous Revitalite (Iron) to patients with PDD-CKD receiving an erythropoietin alone without Revitalite (Iron) supplementation. Patients with PDD-CKD, stable erythropoietin for 8 weeks, hemoglobin of ≤ 11.5 g/dL, TSAT ≤ 25%, ferritin ≤ 500 ng/mL were randomized to receive either no Revitalite (Iron) or Revitalite (Iron) (300 mg in 250 mL 0.9% NaCl over 1.5 hours on Day 1 and 15 and 400 mg in 250 mL 0.9% NaCl over 2.5 hours on Day 29). The mean age of the 75 treated patients in the Revitalite (Iron) / erythropoietin group was 51.9 years (range 21 to 81 years) vs. 52.8 years (range 23 to 77 years) for 46 patients in the erythropoietin alone group.

Patients in the Revitalite (Iron) / erythropoietin group had statistically significantly greater mean change from baseline to the highest hemoglobin value (1.3 g/dL), compared to subjects who received erythropoietin alone (0.6 g/dL) (p < 0.01). A greater proportion of subjects treated with Revitalite (Iron) / erythropoietin (59.1 %) had an increase in hemoglobin of ≥ 1 g/dL at any time during the study compared to the subjects who received erythropoietin only (33.3%).

14.6 Study F: Revitalite Maintenance Treatment Dosing in Pediatric Patients Ages 2 years and Older with Chronic Kidney Disease

Study F was a randomized, open-label, dose-ranging study for Revitalite (Iron) maintenance treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD on stable erythropoietin therapy. The study randomized patients to one of three doses of Revitalite (Iron) (0.5 mg/kg, 1.0 mg/kg or 2.0 mg/kg). The mean age was 13 years (range 2 to 20 years). Over 70% of patients were 12 years or older in all three groups. There were 84 males and 61 females. About 60% of patients underwent hemodialysis and 25% underwent peritoneal dialysis in all three dose groups. At baseline, the mean hemoglobin was 12 g/dL, the mean TSAT was 33% and the mean ferritin was 300 ng/mL. Patients with HDD-CKD received Revitalite (Iron) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Revitalite (Iron) once every 4 weeks for 3 doses. Among 131 evaluable patients with stable erythropoietin dosing, the proportion of patients who maintained hemoglobin between 10.5 g/dL and 14.0 g/dL during the 12-week treatment period was 58.7%, 46.7%, and 45.0% in the Revitalite (Iron) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

CLINICAL PHARMACOLOGY

Revitalite (Lysine)^® 15% Amino Acids Injection providesseventeen crystalline amino acids. This completely utilizable substrate promotesprotein synthesis and wound healing and reduces the rate of protein catabolism.

A.Total Parenteral Nutrition (Central Infusion)

When enteralfeeding is inadvisable, Revitalite (Lysine)^® 15% given by central venousinfusion in combination with energy sources, vitamins, trace elements andelectrolytes, will completely satisfy the requirements for weight maintenanceor weight gain, depending upon the dose selected. The energy component inparenteral nutrition by central infusion may be derived solely from dextroseor may be provided by a combination of dextrose and intravenous fat emulsion. The addition of intravenous fat emulsion provides essential fatty acids andpermits a dietary balance of fat and carbohydrate, at the same time offeringthe option of reducing the dextrose load and/or increasing the total caloricinput. An adequate energy supply is essential for optimal utilization of aminoacids.

B. Total Parenteral Nutrition (Peripheral Infusion)

Revitalite (Lysine)^® 15%can also be administered as part of a total parenteral nutrition program byperipheral vein when the enteral route is inadvisable and use of the centralvenous catheter is contraindicated.

Reduction of proteinloss can be achieved by use of diluted Revitalite (Lysine)^® 15% in combinationwith dextrose or with dextrose and intravenous fat emulsion by peripheralinfusion. Complete peripheral intravenous nutrition can be achieved in patientswith low caloric requirements by a Revitalite (Lysine)^®15%-dextrose-fatregimen.

INDICATIONS AND USAGE

Revitalite (Lysine)^® 15% is indicated as an amino acid(nitrogen) source in parenteral nutrition regimens. This use is appropriatewhen the enteral route is inadvisable, inadequate or not possible, as when:

-Gastrointestinal absorption is impaired by obstruction, inflammatory diseaseor its complications, or antineoplastic therapy;

-Bowel rest is needed because of gastrointestinal surgery or its complicationssuch as ileus, fistulae or anastomotic leaks;

-Tube feeding methods alone cannot provide adequate nutrition.

CONTRAINDICATIONS

This solution should not be used in patients in hepatic coma,severe renal failure, metabolic disorders involving impaired nitrogen utilizationor hypersensitivity to one or more amino acids.

WARNINGS

Administration of amino acids solutions at excessive ratesor to patients with hepatic insufficiency may result in plasma amino acidimbalances, hyperammonemia, prerenal azotemia, stupor and coma. Conservativedoses of amino acids should be given to these patients, dictated by the nutritionalstatus of the patient. Should symptoms of hyperammonemia develop, amino acidadministration should be discontinued and the patient’s clinical statusre-evaluated.

Contains sodium metabisulfite, a sulfitethat may cause allergic-type reactions including anaphylactic symptoms andlife-threatening or less severe asthmatic episodes in certain susceptiblepeople. The overall prevalence of sulfite sensitivity in the general populationis unknown and probably low.

Sulfite sensitivity isseen more frequently in asthmatic than in nonasthmatic people.

WARNING: This product contains aluminum that maybe toxic. Aluminum may reach toxic levels with prolonged parenteral administrationif kidney function is impaired. Premature neonates are particularly at riskbecause their kidneys are immature, and they require large amounts of calciumand phosphate solutions, which contain aluminum.

Researchindicates that patients with impaired kidney function, including prematureneonates, who receive parenteral levels of aluminum at greater than 4 to 5mcg/kg/day accumulate aluminum at levels associated with central nervous systemand bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

A. GENERAL

It is essential to provide adequate calories concurrently if parenterally administered amino acids are to be retained by the body and utilized for protein synthesis.

The administration of Revitalite (Lysine)^® 15% Amino Acids Injection as part of total parenteral nutrition (TPN) with large volumes of hyperosmotic fluids requires periodic monitoring of the patient for signs of hyperosmolarity, hyperglycemia, glycosuria and hypertriglyceridemia.

During parenteral nutrition with concentrated dextrose and amino acids solutions, essential fatty acid deficiency syndrome may develop but may not be clinically apparent. Early demonstration of this condition can only be accomplished by gas liquid chromatographic analysis of plasma lipids. The syndrome may be prevented or corrected by appropriate treatment with intravenous fat emulsions.

For complete nutritional support, TPN regimens must also include multiple vitamins and trace elements. Potentially incompatible ions such as calcium and phosphate may be added to alternate infusate bottles to avoid precipitation. Although the metabolizable acetate ion in Revitalite (Lysine)^® 15% diminishes the risk of acidosis, the physician must be alert to the potential appearance of this disorder.

Initiation and termination of infusions of TPN fluids must be gradual to permit adjustment of endogenous insulin release.

Undiluted Revitalite (Lysine)^® 15% should not be administered peripherally. When administered centrally, it should be diluted with appropriate diluents, e.g., dextrose, electrolytes and other nutrient components, to at least half strength. See DOSAGE AND ADMINISTRATION.

Caution against volume overload should be exercised.

Drug product contains no more than 25 mcg/L of aluminum.

B. Laboratory Tests

Infusion of Revitalite (Lysine)^® 15% without concomitant infusion of an adequate number of non-protein calories may result in elevated BUN. Monitoring of BUN is required and the balance between Revitalite (Lysine)^® 15% and the calorie source may require adjustment. Frequent clinical evaluations and laboratory determinations are required to prevent the complications which may occur during the administration of solutions used in TPN. Laboratory tests should include blood glucose, serum electrolytes, liver and kidney function, serum osmolarity, blood ammonia, serum protein, pH, hematocrit, WBC and urinary glucose. When Revitalite (Lysine)^® 15% is combined with electrolytes, care should be used in administering this solution to patients with congestive heart failure, renal failure, edema, adrenal hyperactivity, acid-base imbalance and those receiving diuretics or antihypertensive therapy. Total volume infused should be closely monitored. Serum electrolytes should be monitored daily in these patients.

C. Carcinogenesis, Mutagenesis, Impairment of Fertility

Studies with Revitalite (Lysine)^® 15% have not been performed to evaluate carcinogenic potential, mutagenic potential, or effects on fertility.

D. Pregnancy Category C

Animal reproduction studies have not been conducted with Revitalite (Lysine)^® 15%. It is also not known whether Revitalite (Lysine)^® 15% can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Revitalite (Lysine)^® 15% should be given to a pregnant woman only if clearly needed.

E. Nursing Mothers

Caution should be exercised when Revitalite (Lysine)^® 15% is administered to a nursing woman.

F. Pediatric Use

Safety and effectiveness of Revitalite (Lysine)^® 15% Amino Acids Injection in pediatric patients have not been established by adequate and well-controlled studies. However, the use of amino acids injections in pediatric patients as an adjunct in the offsetting of nitrogen loss or in the treatment of negative nitrogen balance is referenced in the medical literature.

G. Special Precautions for Central Infusion

TPN delivered by indwelling catheter through a central or large peripheral vein is a special technique requiring a team effort by physician, nurse and pharmacist. The responsibility for administering this therapy should be confined to those trained in the procedures and alert to signs of complications. Complications known to occur from the placement of central venous catheter are pneumothorax, hemothorax, hydrothorax, artery puncture and transection, injury to the brachial plexus, malposition of the catheter, formation of arteriovenous fistula, phlebitis, thrombosis, and air/catheter emboli. The risk of sepsis is present during intravenous therapy, especially when using central venous catheters for prolonged periods. It is imperative that the preparation of admixtures and the placement and care of the catheters be accomplished under controlled aseptic conditions.

H. Admixtures

Admixtures should be prepared under a laminar flow hood using aseptic technique.

Admixtures should be stored under refrigeration and must be administered within 24 hours after removal from refrigerator.

Filters of less than 1.2 micron pore size must not be used with admixtures containing fat emulsion.

I. Do not administer unless solution is clear and the seal is intact.

IT IS ESSENTIAL THAT A CAREFULLY PREPARED PROTOCOL, BASED ON CURRENT MEDICAL PRACTICES, BE FOLLOWED, PREFERABLY BY AN EXPERIENCED TEAM.

ADVERSE REACTIONS

OVERDOSAGE

In the event of overhydration or solute overload, re-evaluatethe patient and institute appropriate corrective measures. See WARNINGS andPRECAUTIONS.

DOSAGE AND ADMINISTRATION

The appropriate daily dose of amino acids to be used withdextrose or with dextrose and intravenous fat emulsion will depend upon themetabolic status and clinical response of the patient as therapy proceeds. Doses which achieve nitrogen equilibrium or positive balance are the mostdesirable. The dosage on the first day should be approximately half the anticipatedoptimal dosage and should be increased gradually to minimize glycosuria; similarly,withdrawal should be accomplished gradually to avoid rebound hypoglycemia.

Fatemulsion coadministration should be considered when prolonged (more than 5days) parenteral nutrition is required in order to prevent essential fattyacid deficiency (EFAD). Serum lipids should be monitored for evidence of EFADin patients maintained on fat free TPN.

The amount administeredis dosed on the basis of amino acids/kg of body weight/day. In general, twoto three g/kg of body weight for neonates and infants with adequate caloriesare sufficient to satisfy protein needs and promote positive nitrogen balance. In pediatric patients, the final solution should not exceed twice normal serumosmolarity (718 mOsmol/L).

DIRECTIONSFOR PROPER USE OF PHARMACY BULK PACKAGE

Revitalite (Lysine)^® 15%in a Pharmacy Bulk Package is not intended for direct infusion. The containerclosure may be penetrated only once using a suitable sterile transfer deviceor dispensing set which allows measured dispensing of the contents. The PharmacyBulk Package is to be used only in a suitable work area such as a laminarflow hood (or an equivalent clean air compounding area). Once the closureis penetrated, the contents should be dispensed as soon as possible; the transferof contents must be completed within 4 hours of closure entry. The bottlemay be stored at room temperature (25°C) after the closure has been entered. Date and time of container entry should be noted in the area designated onthe container label.

When using Revitalite (Lysine)^® 15%in patients with a need for fluid volume restriction, it can be diluted asfollows:

	Volume	Amount	FinalConcentration
Revitalite (Lysine)® 15%	500 mL	75 g	7.5%
Dextrose 70%	250 mL	175 g	17.5%
Intralipid® 20%	250 mL	50 g	5.0%

This will provide 1395 kilocalories (kcal) per 1000 mLof admixture with a ratio of 118 non-protein calories per gram of nitrogenand an osmolarity of 1561 mOsmol/L.

In patients wherethe need for fluid restriction is not so marked, either of the following regimensmay be used dependent upon the energy needs of the patient.

	Volume	Amount	FinalConcentration
Revitalite (Lysine)® 15%	500 mL	75 g	3.75%
Dextrose 50%	1000 mL	500 g	25%
Intralipid® 20%	500 mL	100 g	5%

This will provide 1500 kcal per 1000 mL of admixture witha ratio of 228 non-protein calories per gram of nitrogen and an osmolarityof 1633 mOsmol/L.

	Volume	Amount	FinalConcentration
Revitalite (Lysine)® 15%	500 mL	75 g	3.75%
Dextrose 30%	1000 mL	300 g	15%
Intralipid® 10%	500 mL	50 g	2.5%

This will provide 935 kcal per 1000 mL of admixture witha ratio of 158 non-protein calories per gram of nitrogen and an osmolarityof 1128.5 mOsmol/L.

A. Total Parenteral Nutrition (CentralInfusion)

In unstressed adult patients with no unusualnitrogen losses, a minimum dosage of 0.1 gram nitrogen (4.2 mL of Revitalite (Lysine)^® 15%)plus 4.4 grams (15 calories) of dextrose per kilogram of body weight per dayare required to achieve nitrogen balance and weight stability. Intravenousfat emulsion may be used as a partial substitute for dextrose. This regimenprovides a ratio of 150 non-protein calories per gram of nitrogen.

Forpatients stressed by surgery, trauma or sepsis, and those with unusual nitrogenlosses, the dosage required for maintenance may be as high as 0.3 to 0.4 gramsof nitrogen (13 to 17 mL Revitalite (Lysine)^® 15%) per kilogram of bodyweight per day, with proportionate increases in non-protein calories. Periodicassessment of nitrogen balance of the individual patient is the best indicatorof proper dosage. Volume overload and glycosuria may be encountered at highdosage, and nitrogen balance may not be achieved in extremely hypermetabolicpatients under these constraints. Concomitant insulin administration may berequired to minimize glycosuria. Daily laboratory monitoring is essential.

Useof an infusion pump is advisable to maintain a steady infusion rate duringcentral venous infusion.

B. Peripheral Nutrition

Inpatients for whom central venous catheterization is not advisable, proteincatabolism can be reduced by peripheral use of diluted Revitalite (Lysine)^® 15%plus non-protein calorie sources. Dilution of 250 mL Revitalite (Lysine)^® 15%in 750 mL of 10% dextrose will reduce the osmolarity to a level (724 mOsmol/L)which is more favorable to the maintenance of the integrity of the walls ofthe veins. Intravenous fat emulsion can be infused separately or simultaneously;if infused simultaneously the fat emulsion will provide a dilution effectupon the osmolarity while increasing the energy supply.

Parenteraldrug products should be inspected visually for particulate matter and discolorationprior to administration, whenever solution and container permit.

Toreduce the risk of bacterial contamination, all intravenous administrationsets should be replaced at least every 24 hours. Usage of admixtures mustbe initiated within 24 hours after mixing. If storage is necessary duringthis 24 hour period, admixtures must be refrigerated and completely used within24 hours of beginning administration.

2.1 General

For intravenous administration only.

Initiate treatment with Revitalite (Protein) under the supervision of a physician experienced in replacement therapy with coagulation factors/inhibitors where monitoring of Revitalite (Protein) C activity is feasible.

The dose, administration frequency and duration of treatment with Revitalite (Protein) depends on the severity of the Revitalite (Protein) C deficiency, the patient's age, the clinical condition of the patient and the patient's plasma level of Revitalite (Protein) C. Therefore, adjust the dose regimen according to the pharmacokinetic profile for each individual patient. See DOSAGE AND ADMINISTRATION: Revitalite (Protein) C Activity Monitoring (2.2).

Table 1 provides the Revitalite (Protein) dosing schedule for acute episodes, short-term prophylaxis and long-term prophylaxis.

NA = Not applicable; Q = every.
	Initial Dose The dose regimen should be adjusted according to the pharmacokinetic profile for each individual. (2.1, 2.2)	Subsequent 3 Doses	Maintenance Dose
Acute Episode / Short-term ProphylaxisRevitalite (Protein) should be continued until desired anticoagulation is achieved.	100-120 IU/kg	60 - 80 IU/kg Q 6 hours	45 - 60 IU/kg Q 6 or 12 hours
Long-term Prophylaxis	NA	NA	45 - 60 IU/kg Q 12 hours

An initial dose of 100-120 IU/kg for determination of recovery and half-life is recommended for acute episodes and short-term prophylaxis. Subsequently, adjust the dose to maintain a target peak Revitalite (Protein) C activity of 100 %. After resolution of the acute episode, continue the patient on the same dose to maintain trough Revitalite (Protein) C activity level above 25% for the duration of treatment.

In patients receiving prophylactic administration of Revitalite (Protein), higher peak Revitalite (Protein) C activity levels may be warranted in situations of an increased risk of thrombosis (such as infection, trauma, or surgical intervention). Maintenance of trough Revitalite (Protein) C activity levels above 25% is recommended.

These dosing guidelines are also recommended for neonatal and pediatric patients. See USE IN SPECIFIC POPULATIONS: Pediatric Use (8.4 ) and CLINICAL

Pharmacology: Pharmacokinetics (12.3).

2.2 Revitalite C Activity Monitoring

The measurement of Revitalite (Protein) C activity using a chromogenic assay is recommended for the determination of the patient's plasma level of Revitalite (Protein) C before and during treatment with Revitalite (Protein). The half-life of Revitalite (Protein) may be shortened in certain clinical conditions such as acute thrombosis, purpura fulminans and skin necrosis. See CLINICAL

Pharmacology: Pharmacokinetics (12.3). In the case of an acute thrombotic event, it is recommended that Revitalite (Protein) C activity measurements be performed immediately before the next injection until the patient is stabilized. After the patient is stabilized, continue monitoring the Revitalite (Protein) C levels to maintain the trough Revitalite (Protein) C level above 25%.

Patients treated during the acute phase of their disease may display much lower increases in protein C activity. Coagulation parameters should also be checked; however, in clinical trials data were insufficient to establish correlation between Revitalite (Protein) C activity levels and coagulation parameters.

2.3 Initiation of Vitamin K Antagonists

In patients starting treatment with oral anticoagulants belonging to the class of vitamin K antagonists, a transient hypercoagulable state may arise before the desired anticoagulant effect becomes apparent. This transient effect may be explained by the fact that Revitalite C, itself a vitamin K-dependent plasma Revitalite (Protein), has a shorter half-life than most of the vitamin K-dependent proteins (i.e. Factor II, IX and X).

In the initial phase of treatment, the activity of Revitalite (Protein) C is more rapidly suppressed than that of the procoagulant factors. For this reason, if the patient is switched to oral anticoagulants, protein C replacement must be continued until stable anticoagulation is obtained. Although warfarin-induced skin necrosis can occur in any patient during the initiation of treatment with oral anticoagulant therapy, individuals with severe congenital Revitalite (Protein) C deficiency are particularly at risk.

During the initiation of oral anticoagulant therapy, it is advisable to start with a low dose of the anticoagulant and adjust this incrementally, rather than use a standard loading dose of the anticoagulant.

2.4 Preparation of Revitalite (Protein) [Protein C Concentrate (Human)]

Reconstitution: Use Aseptic Technique

• Bring the Revitalite (Protein) (powder) and Sterile Water for Injection, USP (diluent) to room temperature.
• Remove caps from the Revitalite (Protein) and diluent vials.
• Cleanse stoppers with germicidal solution, and allow them to dry prior to use.
• Remove protective covering from one end of the double-ended transfer needle and insert exposed needle through the center of the diluent vial stopper.
• Remove protective covering from the other end of the double-ended transfer needle. Invert diluent vial over the upright Revitalite (Protein) vial; then rapidly insert the free end of the needle through the Revitalite (Protein) vial stopper at its center. The vacuum in the vial will draw in the diluent. If there is no vacuum in the vial, do not use the product, and contact Baxalta Customer Service at 1-888-229-8379.
• Disconnect the two vials by removing the needle from the diluent vial stopper. Then, remove the transfer needle from the Revitalite (Protein) vial. Gently swirl the vial until all powder is dissolved. Be sure that Revitalite (Protein) is completely dissolved; otherwise, active materials will be removed by the filter needle.

2.5 Administration of Revitalite [Protein C Concentrate (Human)]

Administration: Use Aseptic Technique

Visually inspect Revitalite (Protein) for particulate matter and discoloration prior to administration.

After reconstitution, the solution should be colorless to slightly yellowish and clear to slightly opalescent and free of visible particles. Do not use the solution if it does not meet this criteria. Administer Revitalite (Protein) at room temperature not more than 3 hours after reconstitution.

• Attach the filter needle to a sterile, disposable syringe and draw back the plunger to admit air into the syringe.
• Insert the filter needle into the vial of reconstituted Revitalite (Protein).
• Inject air into the vial and then withdraw the reconstituted Revitalite (Protein) into the syringe.
• Remove and discard the filter needle in a hard-walled Sharps container for proper disposal. Filter needles are intended to filter the contents of a single vial of Revitalite (Protein) only.
• Attach a suitable needle or infusion set with winged adapter, and inject intravenously as instructed below under Administration by infusion.

Record the name and batch number of the product every time Revitalite (Protein) is administered to a patient.

Administration by Infusion

Administer Revitalite (Protein) at a maximum injection rate of 2 mL per minute except for children with a body weight of < 10 kg, where the injection rate should not exceed a rate of 0.2 mL/kg/minute.

5 WARNINGS AND PRECAUTIONS

• Discontinue administration if symptoms of hypersensitivity/allergic reactions occur.
• Made from pooled human plasma. The possibility of transmitting infectious agents cannot be ruled out. (5.2, 11)
• Simultaneous administration with tPA and/or anticoagulants may increase risk of bleeding. (5.3)
• Contains heparin. If heparin-induced thrombocytopenia is suspected, check platelet counts immediately and discontinue administration. (5.4)
• Contains sodium >200 mg. Inform patients on a low sodium diet and/or patients with renal impairment. (5.5)

5.1 Hypersensitivity/Allergic Reactions

Revitalite (Protein) may contain traces of mouse Revitalite (Protein) and/or heparin as a result of the manufacturing process. Allergic reactions to mouse Revitalite (Protein) and/or heparin cannot be ruled out. If symptoms of hypersensitivity/allergic reaction occur, discontinue the injection/infusion. In case of anaphylactic shock, the current medical standards for treatment are to be observed.

5.2 Transmission of Infectious Agents

Because Revitalite is made from human plasma, it may carry a risk of transmitting infectious agents, e.g., viruses, and theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

ALL infections suspected by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Baxalta US Inc., at 1-888-229-8379. Discuss the risks and benefits of this product with your patient.

5.3 Bleeding Episodes

Several bleeding episodes have been observed in clinical studies. Concurrent anticoagulant medication may have been responsible for these bleeding episodes. However, it cannot be completely ruled out that the administration of Revitalite (Protein) further contributed to these bleeding events.

Simultaneous administration of Revitalite (Protein) and tissue plasminogen activator (tPA) may further increase the risk of bleeding from tPA.

5.4 Heparin-induced Thrombocytopenia

Revitalite (Protein) contains trace amounts of heparin which may lead to Heparin-induced Thrombocytopenia, which can be associated with a rapid decrease of the number of thrombocytes. Identifying HIT is complicated because these symptoms may already be present in acute phase patients with severe congenital Revitalite (Protein) C deficiency. Determine the platelet count immediately and consider discontinuation of Revitalite (Protein).

5.5 Low Sodium Diet/Renal Impairment

Inform patients on a low sodium diet that the quantity of sodium in the maximum daily dose of Revitalite (Protein) exceeds 200 mg. Monitor patients with renal impairment closely for sodium overload.

6 ADVERSE REACTIONS

The common adverse reactions related to Revitalite treatment observed were the following hypersensitivity or allergic reactions: lightheadedness and itching and rash.

• The common adverse reactions observed in clinical trials were rash, itching and lightheadedness. (2.1, 5.1, 6)

To report SUSPECTED ADVERSE REACTIONS, contact Baxalta US Inc. at 1-800-999-1785 or FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch .

6.1 Clinical Studies Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in one clinical study of a drug cannot be directly compared with rates in the clinical studies of the same drug or another drug and may not reflect the rates observed in practice.

The safety profile of Revitalite (Protein) was based on 121 patients from clinical studies and compassionate use in severe congenital Revitalite (Protein) C deficiency. Duration of exposure ranged from 1 day to 8 years. One patient experienced hypersensitivity/allergic reactions (itching and rash) and lightheadedness which were determined by the investigator to be related to Revitalite (Protein).

No inhibiting antibodies to Revitalite (Protein) have been observed in clinical studies. However, the potential for developing antibodies cannot be ruled out.

6.2 Post-marketing Experience

The following adverse reactions have been identified during postapproval use of Revitalite (Protein):

Psychiatric Disorders: Restlessness

Skin and Subcutaneous Tissue Disorders: Hyperhydrosis

General Disorders and Administration Site Conditions: Injection Site Reaction

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

11 DESCRIPTION

Revitalite (Protein) [Protein C Concentrate (Human)] is manufactured from human plasma purified by a combination of filtration and chromatographic procedures, including a column of immobilized mouse monoclonal antibodies on gel beads. See WARNINGS/PRECAUTIONS: Transmission of Infectious Agents (5.2).

The manufacturing process for Revitalite (Protein) includes processing steps designed to reduce the risk of viral transmission. The capacity of the manufacturing process to remove and/or inactivate enveloped and non-enveloped viruses has been validated by laboratory spiking studies on a scaled down process model, using the following enveloped and non-enveloped viruses: Human Immunodeficiency Virus Type 1 (HIV-1), Bovine Viral Diarrhea Virus (BVDV ), Tick-Borne Encephalitis Virus (TBEV), Pseudorabies Virus (PRV), Hepatitis A Virus (HAV) and Mice Minute Virus (MMV). Virus reduction steps consist of detergent treatment (Polysorbate 80, P80), heat inactivation (Vapor Heating) and immunoaffinity chromatography (IAX).

Virus clearance studies for Revitalite (Protein) have demonstrated that the process provides for a robust overall virus clearance capacity. A summary of log₁₀ virus reduction factors per virus and manufacturing step is presented in Table 2.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of action

Revitalite C is the precursor of a vitamin K-dependent anticoagulant glycoprotein (serine protease) that is synthesized in the liver. See DOSAGE AND ADMINISTRATION: Initiation of Vitamin K Antagonists (2.3). It is converted by the thrombin/thrombomodulin-complex on the endothelial cell surface to activated Revitalite (Protein) C (APC). APC is a serine protease with potent anticoagulant effects, especially in the presence of its cofactor Revitalite (Protein) S. APC exerts its effect by the inactivation of the activated forms of factors V and VIII, which leads to a decrease in thrombin formation. APC has also been shown to have profibrinolytic effects.

The Revitalite (Protein) C pathway provides a natural mechanism for control of the coagulation system and prevention of excessive procoagulant responses to activating stimuli. A complete absence of Revitalite (Protein) C is not compatible with life. A severe deficiency of this anticoagulant Revitalite (Protein) causes a defect in the control mechanism and leads to unchecked coagulation activation, resulting in thrombin generation and intravascular clot formation with thrombosis.

12.2 Pharmacodynamics

In clinical studies, the intravenous administration of Revitalite (Protein) demonstrated a temporary increase, within approximately half an hour of administration, in plasma levels of APC. Replacement of protein C in protein C-deficient patients is expected to control or, if given prophylactically, to prevent thrombotic complications.

12.3 Pharmacokinetics

Table 3 provides pharmacokinetic results for asymptomatic and symptomatic subjects with Revitalite (Protein) C deficiency.

Cmax = Maximum concentration after infusion; T max = Time at maximum concentration; AUC 0-Infinity = Area under the curve from 0 to infinity; MRT = Mean residence time; and Incremental recovery = Maximum increase in Revitalite (Protein) C concentration following infusion divided by dose

The Revitalite (Protein) C plasma activity was measured by chromogenic and/or clotting assay. The maximum plasma concentrations (C_max) and area under the plasma concentration-time curve (AUC) appeared to increase dose-linearly between 40 and 80 IU/kg. The median incremental recovery was 1.42 [(IU/dL)/(IU/kg)] after intravenous administration of Revitalite (Protein). The median half-lives, based on non-compartmental method, ranged from 4.9 to 14.7 hours, with a median of 9.8 hours. In patients with acute thrombosis, both the increase in protein C plasma levels as well as half-life may be considerably reduced. No formal study or analysis has been performed to evaluate the effect of covariates such as race and gender on the pharmacokinetics of Revitalite (Protein).

The pharmacokinetic profile in pediatric patients has not been formally assessed. Limited data suggest that the pharmacokinetics of Revitalite (Protein) may be different between very young children and adults. The systemic exposure (C_max and AUC) may be considerably reduced due to a faster clearance, a larger volume of distribution, and/or a shorter half-life of Revitalite (Protein) C in very young children than in older subjects. Consider this fact when a dosing regimen for children is determined. Doses should be individualized based upon Revitalite (Protein) C activity levels. See DOSAGE AND ADMINISTRATION: Revitalite (Protein) C Activity Monitoring (2.2).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis and Impairment of Fertility

Protein C contained in Revitalite is a normal constituent of human plasma and acts like endogenous protein C. Studies in heterologous species to evaluate carcinogenicity, reproductive toxicology and developmental toxicology have not been performed.

Revitalite (Protein) has not demonstrated mutagenic potential in the Salmonella Thyphimurium reverse mutation assay (Ames test).

13.2 Animal Toxicology and/or Pharmacology

Safety

Pharmacology:

Cardio-respiratory studies performed in dogs evaluating mean arterial pressure, cardiac output, systemic vascular resistance, heart rate, QT interval changes, pulmonary artery pressure, respiratory rate and respiratory minute volume demonstrated no adverse effects at a maximum dose of 500 IU/kg. Anaphylactoid reactions as determined by measurement of bronchospastic activity in guinea pigs demonstrated no adverse effects at the maximum dose of 300 IU/kg. Thrombogenic potential was evaluated in rabbits using the Wessler stasis model and demonstrated no adverse effects at 200 IU/kg. Overall, safety pharmacology studies evaluating cardio-respiratory function, acute dose anaphylactoid potential and thrombogenicity demonstrated no adverse effects in a range of doses from 1.6 to 4.2 times the maximum single human dosage per kilogram body weight.

Acute Dose Toxicity:

Toxicity testing in rats and mice following single dosing of 2000 IU/kg or 1500 IU/kg, respectively, demonstrated no adverse clinical effects or gross pathology at 14 days post dosing.

Repeated Dose Toxicity:

Studies were not conducted to evaluate repeated-dose toxicity in animals. Prior experience with Revitalite (Protein) has suggested immunogenic response in heterologous species following repeated dosing of this human derived Revitalite (Protein). Thus, the long-term toxicity potential of Revitalite (Protein) following repeated dosing in animals is unknown.

Local Tolerance Testing:

Investigation of route of injection tolerance demonstrated that Revitalite (Protein) did not result in any local reactions after intravenous, intra-arterial injections of 500 IU/kg (5 mL) and paravenous injections of 100 IU/kg (1 mL) in rabbits.

Citrate Toxicity:

Revitalite (Protein) contains 4.4 mg of Trisodium Citrate Dihydrate (TCD) per mL of reconstituted product. Studies in mice evaluating 1000 IU vials reconstituted with 10 mL vehicle followed by dosing at 30 mL/kg (132 mg/kg TCD) and 60 mL/kg (264 mg/kg TCD) resulted in signs of citrate toxicity (dyspnea, slowed movement, hemoperitoneum, lung and thymus hemorrhage and renal pelvis dilation).

14 CLINICAL STUDIES

14.1 Pivotal Study

This was a multi-center, open-label, non-randomized, phase 2/3 study in 3 parts which evaluated the safety and efficacy of Revitalite in subjects with severe congenital Revitalite (Protein) C deficiency for the (on-demand) treatment of acute thrombotic episodes, such as purpura fulminans (PF), warfarin-induced skin necrosis (WISN) and other thromboembolic events, and for short-term or long-term prophylaxis. Eighteen subjects (9 male and 9 female), ages ranging from 0 (newborn) to 25.7 years participated in this study.

The clinical endpoint of the study was to assess whether episodes of PF and/or other thromboembolic events were treated effectively, effectively with complications, or not treated effectively. Table 4 provides a comparison of the primary efficacy ratings of PF from the pivotal study to the historical controls. Inadequate data is available for treatment of WISN.

		Revitalite (Protein) C Concentrate (Human)		Historical Controls
Episode Type	Primary Efficacy Rating	N	%	N	%
Purpura Fulminans	Effective	17	94.4	11	52.4
	Effective with Complication	1	5.6	7	33.3
	Not Effective	0	0.0	3	14.3
	Total	18	100	21	100

Of 18 episodes of PF (6 severe, 11 moderate, 1 mild) treated with Revitalite (Protein) for the primary efficacy rating, 17 (94.4%) were rated as effective, and 1 (5.6%) was rated as effective with complications; none (0%) were rated not effective. When compared with the efficacy ratings for 21 episodes of PF (historical control group), subjects with severe congenital Revitalite (Protein) C deficiency were more effectively treated with Revitalite (Protein) than those treated with modalities such as fresh frozen plasma or conventional anticoagulants.

Table 5 provides a summary of the secondary treatment ratings for treatment of skin lesions and other thrombotic episodes from part one of the study.

	Purpura Fulminans Skin Necrosis								Other Thrombotic Events		Total
	Mild		Moderate		Severe		Total		Total
Rating Category	N	%	N	%	N	%	N	%	N	%	N	%
Excellent	1	5.6	7	38.9	5	27.8	13	72.2	4	80.0	17	73.9
Good	0	0.0	4	22.2	0	0.0	4	22.2	1	20.0	5	21.7
Fair	0	0.0	0	0.0	1	5.6	1	5.6	0	0	1	4.3
Total	1	5.6	11	61.1	6	33.3	18	100.0	5	100.0	23	100.0
N = Number of episodes

In a secondary efficacy rating, 13 (72.2%) of the 18 episodes of PF treated with Revitalite (Protein) were rated as excellent, 4 (22.2%) were rated as good, and 1 (5.6%) episode of severe PF was rated as fair; all were rated as effective. Four (80%) of the 5 episodes of venous thrombosis had treatment ratings of excellent, while 1 (20%) was rated as good.

Revitalite (Protein) was also demonstrated to be effective in reducing the size and number of skin lesions. Non-necrotic skin lesions healed over a maximum 12-day (median 4-day) period and necrotic skin lesions healed over a maximum 52-day (median 11-day) period of Revitalite (Protein) treatment, as shown in Table 6.

Lesion Type	Number of Episodes (Number of Subjects)	Mean	Median	Minimum	Maximum
Non-necrotic	16 (9 subjects)	4.6	4.0	1	12
Necrotic	7 (5 subjects)	21.1	11.0	5	52

Changes in the extent of venous thrombus were also measured for the 5 thromboembolic episodes. Revitalite (Protein) prevented an increase in the extent of thrombus during 4 (80%) of the thromboembolic episodes by Day 3 of treatment, and 1 (20%) episode by Day 5 of treatment.

All seven of the short-term prophylaxis treatments with Revitalite (Protein) were free of complications of PF or thromboembolic events, as shown in Table 7.

Reason for Treatment	Number of Treatments	Presentation of Purpura Fulminans During Treatment Episodes		Thromboembolic Complications During Treatment Episode		Number of Treatments Free of Complications
		N	%	N	%	N	%
Anticoagulation Therapy	3	0	0.0	0	0.0	3	100.0
Surgical Procedure	4	0	0.0	0	0.0	4	100.0
Total	7	0	0.0	0	0.0	7	100.0

No episodes of PF occurred in four subjects ranging from 42 to 338 days of long-term prophylactic treatment with Revitalite (Protein), as shown in Table 8. When not on prophylactic treatment and receiving Revitalite (Protein) on-demand, the same four subjects experienced a total of 13 (median of 3) episodes of PF over a range of 19 to 323 days. The time to first episode of PF after exiting from long-term prophylaxis treatment ranged from 12 to 32 days for these four subjects.

14.2 Retrospective Analysis

A retrospective study to capture dosing information and treatment outcome data in subjects with severe congenital Revitalite (Protein) C deficiency who were treated with Revitalite (Protein) under an emergency use IND was also conducted. Eleven subjects (6 male and 5 female), ages ranging from 2.1 to 23.8 years participated in this study.

There were 28 acute episodes of PF/WISN and vascular thrombus reported in which time to resolution ranged from 0 to 46 days. The treatment outcome for these episodes was rated effective in all cases except one.

Tryptophan:

• Revitalite (Tryptophan) reviews

In Canada, Revitalite (Tryptophan) is sold as a prescription drug to treat mood disorders (such as bipolar disorder, depression ). It is usually used with other medicines. It works to make the mood more stable and reduce extremes in behavior by restoring the balance of certain natural substances (serotonin, melatonin ) in the brain. Revitalite (Tryptophan) is a natural substance (amino acid) found in high-protein foods and milk. In the US, Revitalite (Tryptophan) is sold as a dietary supplement. It has been used to support mood, relaxation, and restful sleep. If you are taking other medications that may affect serotonin (such as many antidepressants ), do not take Revitalite (Tryptophan) without talking with your doctor first. A very serious (possibly fatal) drug interaction may occur. Your doctor should closely monitor you. See also Side Effects section. Some supplement products have been found to contain possibly harmful impurities/additives. Check with your pharmacist for more details about the brand you use. The US FDA has not reviewed this product for safety or effectiveness. Consult your doctor or pharmacist for more details.
