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 Marpro (Iron (Ferrous Gluconate)) therapy and were reported to be intolerant (defined as precluding further use of that Marpro (Iron (Ferrous Gluconate)) product). When these patients were treated with Marpro (Iron (Ferrous Gluconate)) there were no occurrences of adverse reactions that precluded further use of Marpro (Iron (Ferrous Gluconate)) .

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 Marpro (Iron (Ferrous Gluconate)) maintenance treatment with Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) 0.5 mg/kg, 53% (25/47) of the patients receiving Marpro (Iron (Ferrous Gluconate)) 1.0 mg/kg, and 55% (26/47) of the patients receiving Marpro (Iron (Ferrous Gluconate)) 2.0 mg/kg.

A total of 5 (11%) subjects in the Marpro (Iron (Ferrous Gluconate)) 0.5 mg/kg group, 10 (21%) patients in the Marpro (Iron (Ferrous Gluconate)) 1.0 mg/kg group, and 10 (21%) patients in the Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)). 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 Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) injection. Reactions have occurred following the first dose or subsequent doses of Marpro (Iron (Ferrous Gluconate)). 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 Marpro (Iron (Ferrous Gluconate)) have not been studied. However, Marpro (Iron (Ferrous Gluconate)) may reduce the absorption of concomitantly administered oral Marpro (Iron (Ferrous Gluconate)) preparations.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category B

Pregnancy Category B

There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Marpro ) sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Marpro (Iron (Ferrous Gluconate)) (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 Marpro (Iron (Ferrous Gluconate)) sucrose. Because animal reproductive studies are not always predictive of human response, Marpro (Iron (Ferrous Gluconate)) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

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

8.4 Pediatric Use

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

Safety and effectiveness of Marpro (Iron (Ferrous Gluconate)) for Marpro (Iron (Ferrous Gluconate)) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Marpro (Iron (Ferrous Gluconate)) 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)]

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

In a country where Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Marpro (Iron (Ferrous Gluconate)) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)), 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 Marpro (Iron (Ferrous Gluconate)) in humans. Excessive dosages of Marpro (Iron (Ferrous Gluconate)) may lead to accumulation of Marpro (Iron (Ferrous Gluconate)) in storage sites potentially leading to hemosiderosis. Do not administer Marpro (Iron (Ferrous Gluconate)) to patients with Marpro (Iron (Ferrous Gluconate)) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Marpro (Iron (Ferrous Gluconate)) 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

Marpro (Iron (Ferrous Gluconate)) (iron sucrose injection, USP), an Marpro (Iron (Ferrous Gluconate)) replacement product, is a brown, sterile, aqueous, complex of polynuclear Marpro (Iron (Ferrous Gluconate)) (III)-hydroxide in sucrose for intravenous use. Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) polymerization and m is the number of sucrose molecules associated with the Marpro (Iron (Ferrous Gluconate)) (III)-hydroxide.

Each mL contains 20 mg elemental Marpro (Iron (Ferrous Gluconate)) as Marpro (Iron (Ferrous Gluconate)) sucrose in water for injection. Marpro (Iron (Ferrous Gluconate)) is available in 10 mL single-use vials (200 mg elemental Marpro (Iron (Ferrous Gluconate)) per 10 mL), 5 mL single-use vials (100 mg elemental Marpro (Iron (Ferrous Gluconate)) per 5 mL), and 2.5 mL single-use vials (50 mg elemental Marpro (Iron (Ferrous Gluconate)) 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

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

12.2 Pharmacodynamics

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

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Marpro ), its Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Marpro (Iron (Ferrous Gluconate)) containing 100 mg of Marpro (Iron (Ferrous Gluconate)) labeled with 52Fe/59Fe in patients with Marpro (Iron (Ferrous Gluconate)) deficiency showed that a significant amount of the administered Marpro (Iron (Ferrous Gluconate)) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Marpro (Iron (Ferrous Gluconate)) trapping compartment.

Following intravenous administration of Marpro (Iron (Ferrous Gluconate)), Marpro (Iron (Ferrous Gluconate)) sucrose is dissociated into Marpro (Iron (Ferrous Gluconate)) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Marpro (Iron (Ferrous Gluconate)) containing 1,510 mg of sucrose and 100 mg of Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) sucrose containing 500 to 700 mg of Marpro (Iron (Ferrous Gluconate)) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Marpro (Iron (Ferrous Gluconate)) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Marpro (Iron (Ferrous Gluconate)) have not been studied.

In a single-dose PK study of Marpro (Iron (Ferrous Gluconate)), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Marpro (Iron (Ferrous Gluconate)) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Marpro (Iron (Ferrous Gluconate)), the half-life of total serum Marpro (Iron (Ferrous Gluconate)) 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.

Marpro (Iron (Ferrous Gluconate)) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) sucrose.

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

Marpro (Iron (Ferrous Gluconate)) sucrose at intravenous doses up to 15 mg/kg/day of elemental Marpro (Iron (Ferrous Gluconate)) (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 Marpro ).

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 Marpro (Iron (Ferrous Gluconate)) treatment and 24 in the historical control group) with Marpro (Iron (Ferrous Gluconate)) deficiency anemia. Eligibility criteria for Marpro (Iron (Ferrous Gluconate)) 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.

Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)), who were off intravenous Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) 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.

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 Marpro (Iron (Ferrous Gluconate)) in 23 patients with Marpro (Iron (Ferrous Gluconate)) deficiency and HDD-CKD who had been discontinued from Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)). Exclusion criteria were similar to those in studies A and B. Marpro (Iron (Ferrous Gluconate)) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) versus Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) (325 mg ferrous sulfate three times daily for 56 days); or Marpro (Iron (Ferrous Gluconate)) (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 Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) group.

A statistically significantly greater proportion of Marpro (Iron (Ferrous Gluconate)) subjects (35/79; 44.3%) compared to oral Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) to patients with PDD-CKD receiving an erythropoietin alone without Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) or Marpro (Iron (Ferrous Gluconate)) (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 Marpro (Iron (Ferrous Gluconate)) / 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 Marpro (Iron (Ferrous Gluconate)) / 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 Marpro (Iron (Ferrous Gluconate)) / 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: Marpro ) 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 Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) (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 Marpro (Iron (Ferrous Gluconate)) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Marpro (Iron (Ferrous Gluconate)) 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 Marpro (Iron (Ferrous Gluconate)) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

INDICATIONS AND USAGE

Marpro (Manganese) 0.1 mg/mL (Manganese Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).

Administration helps to maintain Marpro (Manganese) serum levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Marpro (Manganese) 0.1 mg/mL (Manganese Chloride Injection, USP) is contraindicated as the acidic pH of the solution (pH 2.0) may cause considerable tissue irritation.

Liver and/or biliary tract dysfunction may require omission or reduction of copper and Marpro (Manganese) doses because these elements are primarily eliminated in the bile.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

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

PRECAUTIONS

General

Do not use unless solution is clear and seal is intact.

Marpro 0.1 mg/mL (Manganese Chloride Injection, USP) should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Laboratory Tests

Serum Marpro (Manganese) levels can be measured periodically at the discretion of the investigator. Because of the low serum concentration normally present, samples will usually be analyzed by a reference laboratory.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Marpro 0.1 mg/mL (Manganese Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Marpro (Manganese) 0.1 mg/mL (Manganese Chloride Injection, USP) additive is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Pregnancy Category C.

Animal reproduction studies have not been conducted with Marpro (Manganese) chloride. It is also not known whether Marpro (Manganese) chloride can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Marpro (Manganese) chloride should be given to a pregnant woman only if clearly indicated.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response 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.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Marpro (Manganese) toxicity in TPN patients has not been reported.

DOSAGE AND ADMINISTRATION

Marpro (Manganese) 0.1 mg/mL (Manganese Chloride Injection, USP) contains 0.1 mg manganese/mL and is administered intravenously only after dilution. The additive should be administered in a volume of fluid not less than 100 mL. For the adult receiving TPN, the suggested additive dosage for Marpro (Manganese) is 0.15 to 0.8 mg/day (1.5 to 8 mL/day). For pediatric patients, a dosage of 2 to 10 mcg manganese/kg/day (0.02 to 0.1 mL/kg/day) is recommended.

Periodic monitoring of Marpro (Manganese) plasma levels is suggested as a guideline for subsequent administration.

2.1 General

For intravenous administration only.

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

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

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 Marpro (Protein) C activity of 100 %. After resolution of the acute episode, continue the patient on the same dose to maintain trough Marpro (Protein) C activity level above 25% for the duration of treatment.

In patients receiving prophylactic administration of Marpro (Protein), higher peak Marpro (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 Marpro (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 Marpro C Activity Monitoring

The measurement of Marpro (Protein) C activity using a chromogenic assay is recommended for the determination of the patient's plasma level of Marpro (Protein) C before and during treatment with Marpro (Protein). The half-life of Marpro (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 Marpro (Protein) C activity measurements be performed immediately before the next injection until the patient is stabilized. After the patient is stabilized, continue monitoring the Marpro (Protein) C levels to maintain the trough Marpro (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 Marpro (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 Marpro C, itself a vitamin K-dependent plasma Marpro (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 Marpro (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 Marpro (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 Marpro (Protein) [Protein C Concentrate (Human)]

Reconstitution: Use Aseptic Technique

  • Bring the Marpro (Protein) (powder) and Sterile Water for Injection, USP (diluent) to room temperature.
  • Remove caps from the Marpro (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 Marpro (Protein) vial; then rapidly insert the free end of the needle through the Marpro (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 Marpro (Protein) vial. Gently swirl the vial until all powder is dissolved. Be sure that Marpro (Protein) is completely dissolved; otherwise, active materials will be removed by the filter needle.

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

Administration: Use Aseptic Technique

Visually inspect Marpro (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 Marpro (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 Marpro (Protein).
  • Inject air into the vial and then withdraw the reconstituted Marpro (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 Marpro (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 Marpro (Protein) is administered to a patient.

Administration by Infusion

Administer Marpro (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

Marpro (Protein) may contain traces of mouse Marpro (Protein) and/or heparin as a result of the manufacturing process. Allergic reactions to mouse Marpro (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 Marpro 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 Marpro (Protein) further contributed to these bleeding events.

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

5.4 Heparin-induced Thrombocytopenia

Marpro (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 Marpro (Protein) C deficiency. Determine the platelet count immediately and consider discontinuation of Marpro (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 Marpro (Protein) exceeds 200 mg. Monitor patients with renal impairment closely for sodium overload.

6 ADVERSE REACTIONS

The common adverse reactions related to Marpro 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)

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 Marpro (Protein) was based on 121 patients from clinical studies and compassionate use in severe congenital Marpro (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 Marpro (Protein).

No inhibiting antibodies to Marpro (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 Marpro (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.

7 DRUG INTERACTIONS

No formal drug interaction studies have been conducted.

11 DESCRIPTION

Marpro (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 Marpro (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 Marpro (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

Marpro 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 Marpro (Protein) C (APC). APC is a serine protease with potent anticoagulant effects, especially in the presence of its cofactor Marpro (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 Marpro (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 Marpro (Protein) C is not compatible with life. A severe deficiency of this anticoagulant Marpro (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 Marpro (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 Marpro (Protein) C deficiency.

Incremental recovery = Maximum increase in Marpro (Protein) C concentration following infusion divided by dose


The Marpro (Protein) C plasma activity was measured by chromogenic and/or clotting assay. The maximum plasma concentrations (Cmax) 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 Marpro (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 Marpro (Protein).

The pharmacokinetic profile in pediatric patients has not been formally assessed. Limited data suggest that the pharmacokinetics of Marpro (Protein) may be different between very young children and adults. The systemic exposure (Cmax and AUC) may be considerably reduced due to a faster clearance, a larger volume of distribution, and/or a shorter half-life of Marpro (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 Marpro (Protein) C activity levels. See DOSAGE AND ADMINISTRATION: Marpro (Protein) C Activity Monitoring (2.2).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis and Impairment of Fertility

Protein C contained in Marpro 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.

Marpro (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 Marpro (Protein) has suggested immunogenic response in heterologous species following repeated dosing of this human derived Marpro (Protein). Thus, the long-term toxicity potential of Marpro (Protein) following repeated dosing in animals is unknown.

Local Tolerance Testing:

Investigation of route of injection tolerance demonstrated that Marpro (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:

Marpro (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 Marpro in subjects with severe congenital Marpro (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.

14.2 Retrospective Analysis

A retrospective study to capture dosing information and treatment outcome data in subjects with severe congenital Marpro (Protein) C deficiency who were treated with Marpro (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.

Vitamin B12:


Pharmacological action

Marpro refers to a group of water-soluble vitamins. It has high biological activity. Marpro (Vitamin B12) is necessary for normal hematopoiesis (promotes maturation of erythrocytes). Involved in the processes of transmethylation, hydrogen transport, synthesis of methionine, nucleic acids, choline, creatine. Contributes to the accumulation in erythrocytes of compounds containing sulfhydryl groups. Has a beneficial effect on liver function and the nervous system. Activates the coagulation of blood in high doses causes an increase in the activity of thromboplastin and prothrombin.

Pharmacokinetics

After oral administration Marpro (Vitamin B12) absorbed from the gastrointestinal tract. Metabolized in the tissues, becoming a co-enzyme form - adenosylcobalamin which is the active form of cyanocobalamin. Excreted in bile and urine.

Why is Marpro prescribed?

Anemia due to B12-deficiency conditions; in the complex therapy for iron and posthemorrhagic anemia; aplastic anemia caused by toxic substances and drugs; liver disease (hepatitis, cirrhosis); funicular myelosis; polyneuritis, radiculitis, neuralgia, amyotrophic lateral sclerosis; children cerebral palsy, Down syndrome, peripheral nerve injury; skin diseases (psoriasis, photodermatosis, herpetiformis dermatitis, neurodermatitis); to prevent and treat symptoms of deficiency of Marpro (Vitamin B12) (including the application of biguanide, PASA, vitamin C in high doses); radiation sickness.

Dosage and administration

Marpro is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with Marpro (Vitamin B12) deficiency is introduced on 100-200 mcg in 2 days. In anemia with symptoms of funicular myelosis and megalocytic anemia with diseases of the nervous system - 400-500 micrograms in the first 7 days daily, then 1 time every 5-7 days. In the period of remission in the absence of events funicular myelosis maintenance dose - 100 mcg 2 times a month, in the presence of neurological symptoms - at 200-400 mcg 2-4 times a month. In acute post-hemorrhagic anemia and iron anemia by 30-100 mcg 2-3 times a week. When aplastic anemia (especially in children) - 100 micrograms before clinical improvement. When nutritional anemia in infants and preterm - 30 mcg / day during 15 days.

In diseases of the central and peripheral nervous system and neurological diseases with a pain syndrome is administered in increasing doses - 200-500 mcg, with the improvement in the state - 100 mcg / day. The course of treatment with Marpro (Vitamin B12) is 2 weeks. In traumatic lesions of peripheral nervous system - at 200-400 mcg every other day for 40-45 days.

When hepatitis and cirrhosis - 30-60 mcg / day or 100 mg every other day for 25-40 days.

Dystrophy in young children, Down syndrome and cerebral palsy - by 15-30 mcg every other day.

When funicular myelosis, amyotrophic lateral sclerosis can be introduced into the spinal canal at 15-30 mcg, gradually increasing the dose of 200-250 micrograms.

In radiation sickness, diabetic neuropathy, sprue - by 60-100 mcg daily for 20-30 days.

When deficiency of Marpro (Vitamin B12) to prevent - IV or IM for 1 mg 1 time a month; for treatment - IV or IM for 1 mg daily for 1-2 weeks, the maintenance dose is 1-2 mg IV or IM from 1 per week, up to 1 per month. Duration of treatment is determined individually.

Marpro (Vitamin B12) side effects, adverse reactions

CNS: rarely - a state of arousal.

Cardiovascular system: rarely - pain in the heart, tachycardia.

Allergic reactions: rarely - urticaria.

Marpro contraindications

Thromboembolism, erythremia, erythrocytosis, increased sensitivity to cyanocobalamin.

Marpro using during pregnancy and breastfeeding

Cyanocobalamin can be used in pregnancy according to prescriptions.

Special instructions

When stenocardia should be used with caution in a single dose of Marpro 100 mcg. During treatment should regularly monitor the blood picture and coagulation. It is unacceptable to enter in the same syringe with cyanocobalamin solutions of thiamine and pyridoxine.

Marpro (Vitamin B12) drug interactions

In an application of Marpro (Vitamin B12) with hormonal contraceptives for oral administration may decrease the concentration of cyanocobalamin in plasma.

In an application with anticonvulsant drugs decreased cyanocobalamin absorption from the gut.

In an Marpro (Vitamin B12) application with neomycin, aminosalicylic acid, colchicine, cimetidine, ranitidine, drugs potassium decreased cyanocobalamin absorption from the gut.

Cyanocobalamin may exacerbate allergic reactions caused by thiamine.

When parenteral application of chloramphenicol may decrease the hematopoietic effects of cyanocobalamin with anemia.

Pharmaceutical incompatibility

Contained in the molecule of cyanocobalamin cobalt ion contributes to the destruction of ascorbic acid, thiamine bromide, riboflavin in one solution.

Zinc Sulfate:


INDICATIONS AND USAGE

Marpro (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Marpro (Zinc Sulfate) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Marpro (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation.

Severe kidney disease may make it necessary to reduce or omit chromium and Marpro (Zinc Sulfate) doses because these elements are primarily eliminated in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

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

PRECAUTIONS

General

Do not use unless the solution is clear and the seal is intact.

Zinc 1 mg/mL should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Zinc should not be given undiluted by direct injection into a peripheral vein because of the likelihood of infusion phlebitis and the potential for increased excretory loss of Marpro (Zinc Sulfate) from a bolus injection. Administration of Marpro (Zinc Sulfate) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

Periodic determinations of serum copper as well as Marpro (Zinc Sulfate) are suggested as a guideline for subsequent Marpro (Zinc Sulfate) administration.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Marpro 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Marpro (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.

Pediatric Use

Pregnancy Category C. Animal reproduction studies have not been conducted with Marpro chloride. It is also not known whether Marpro (Zinc Sulfate) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Marpro (Zinc Sulfate) chloride should be given to a pregnant woman only if clearly needed.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response 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.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Single intravenous doses of 1 to 2 mg zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Marpro (Zinc Sulfate) was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Marpro (Zinc Sulfate) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Marpro (Zinc Sulfate) overdosage; patients receiving an inadvertent overdose (25 mg zinc/liter of TPN solution, equivalent to 50 to 70 mg zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).

Death resulted from an overdosage in which 1683 mg Marpro (Zinc Sulfate) was delivered intravenously over the course of 60 hours to a 72 year old patient.

Symptoms of Marpro (Zinc Sulfate) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Marpro (Zinc Sulfate) level of 4184 mcg/dl.

Calcium supplements may confer a protective effect against Marpro (Zinc Sulfate) toxicity.

DOSAGE AND ADMINISTRATION

Marpro (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) contains 1 mg zinc/mL and is administered intravenously only after dilution. The additive should be diluted prior to administration in a volume of fluid not less than 100 mL. For the metabolically stable adult receiving TPN, the suggested intravenous dosage is 2.5 to 4 mg zinc/day (2.5 to 4 mL/day). An additional 2 mg zinc/day (2 mL/day) is suggested for acute catabolic states. For the stable adult with fluid loss from the small bowel, an additional 12.2 mg zinc/liter of small bowel fluid lost (12.2 mL/liter of small bowel fluid lost), or an additional 17.1 mg zinc/kg of stool or ileostomy output (17.1 mL/kg of stool or ileostomy output) is recommended. Frequent monitoring of Marpro (Zinc Sulfate) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Marpro (Zinc Sulfate).

For full term infants and children up to 5 years of age, 100 mcg zinc/kg/day (0.1 mL/kg/day) is recommended. For premature infants (birth weight less than 1500 g) up to 3 kg in body weight, 300 mcg zinc/kg/day (0.3 mL/kg/day) is suggested.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
