3 DOSAGE FORMS AND STRENGTHS

4 CONTRAINDICATIONS

5 WARNINGS AND PRECAUTIONS

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 Ferro Sanol Duodenal. 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 Ferro Sanol Duodenal immediately. Monitor patients for signs and symptoms of hypersensitivity during and after Ferro Sanol Duodenal administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Ferro Sanol Duodenal when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Most reactions associated with intravenous Ferro Sanol Duodenal preparations occur within 30 minutes of the completion of the infusion .

5.2 Hypotension

Ferro Sanol Duodenal may cause clinically significant hypotension. Monitor for signs and symptoms of hypotension following each administration of Ferro Sanol Duodenal. Hypotension following administration of Ferro Sanol Duodenal may be related to the rate of administration and/or total dose administered .

5.3 Ferro Sanol Duodenal Overload

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

6.1 Adverse Reactions in Clinical Trials

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in practice.

Adverse Reactions in Adults Patients with CKD

Adverse Reactions in Adult Patients with CKD

The frequency of adverse reactions associated with the use of Ferro Sanol Duodenal has been documented in six clinical trials involving 231 patients with HDD-CKD, 139 patients with NDD-CKD and 75 patients with PDD-CKD. Treatment-emergent adverse reactions reported by ≥ 2% of treated patients in the six clinical trials for which the rate for Ferro Sanol Duodenal exceeds the rate for comparator are listed by indication in Table 1. Patients with HDD-CKD received 100 mg doses at 10 consecutive dialysis sessions until a cumulative dose of 1000 mg was administered. Patients with NDD-CKD received either 5 doses of 200 mg over 2 weeks or 2 doses of 500 mg separated by fourteen days, and patients with PDD-CKD received 2 doses of 300 mg followed by a dose of 400 mg over a period of 4 weeks.

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

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 Ferro Sanol Duodenal maintenance treatment with Ferro Sanol Duodenal 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 Ferro Sanol Duodenal 0.5 mg/kg, 53% (25/47) of the patients receiving Ferro Sanol Duodenal 1.0 mg/kg, and 55% (26/47) of the patients receiving Ferro Sanol Duodenal 2.0 mg/kg.

A total of 5 (11%) subjects in the Ferro Sanol Duodenal 0.5 mg/kg group, 10 (21%) patients in the Ferro Sanol Duodenal 1.0 mg/kg group, and 10 (21%) patients in the Ferro Sanol Duodenal 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 Ferro Sanol Duodenal. 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 Ferro Sanol Duodenal 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 Ferro Sanol Duodenal injection. Reactions have occurred following the first dose or subsequent doses of Ferro Sanol Duodenal. 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 Ferro Sanol Duodenal have not been studied. However, Ferro Sanol Duodenal may reduce the absorption of concomitantly administered oral Ferro Sanol Duodenal 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, Ferro Sanol Duodenal sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Ferro Sanol Duodenal and revealed no evidence of harm to the fetus due to Ferro Sanol Duodenal sucrose. Because animal reproductive studies are not always predictive of human response, Ferro Sanol Duodenal should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

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

8.4 Pediatric Use

Safety and effectiveness of Ferro Sanol Duodenal for Ferro Sanol Duodenal replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.

Safety and effectiveness of Ferro Sanol Duodenal for Ferro Sanol Duodenal maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Ferro Sanol Duodenal 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 ]

Ferro Sanol Duodenal has not been studied in patients younger than 2 years of age.

In a country where Ferro Sanol Duodenal 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 Ferro Sanol Duodenal, several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Ferro Sanol Duodenal or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Ferro Sanol Duodenal 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 Ferro Sanol Duodenal, 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 Ferro Sanol Duodenal in humans. Excessive dosages of Ferro Sanol Duodenal may lead to accumulation of Ferro Sanol Duodenal in storage sites potentially leading to hemosiderosis. Do not administer Ferro Sanol Duodenal to patients with Ferro Sanol Duodenal overload.

Toxicities in single-dose studies in mice and rats, at intravenous Ferro Sanol Duodenal 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

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

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

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

12.2 Pharmacodynamics

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

12.3 Pharmacokinetics

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

Following intravenous administration of Ferro Sanol Duodenal, Ferro Sanol Duodenal sucrose is dissociated into Ferro Sanol Duodenal and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Ferro Sanol Duodenal containing 1,510 mg of sucrose and 100 mg of Ferro Sanol Duodenal in 12 healthy adults, 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Ferro Sanol Duodenal 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 Ferro Sanol Duodenal sucrose containing 500 to 700 mg of Ferro Sanol Duodenal in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Ferro Sanol Duodenal was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Ferro Sanol Duodenal have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

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

Ferro Sanol Duodenal is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Ferro Sanol Duodenal 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 Ferro Sanol Duodenal sucrose.

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

Ferro Sanol Duodenal sucrose at intravenous doses up to 15 mg/kg/day of elemental Ferro Sanol Duodenal (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 Ferro Sanol Duodenal.

14.1 Study A: Hemodialysis Dependent-Chronic Kidney Disease

Study A was a multicenter, open-label, historically-controlled study in 101 patients with HDD-CKD (77 patients with Ferro Sanol Duodenal treatment and 24 in the historical control group) with Ferro Sanol Duodenal deficiency anemia. Eligibility criteria for Ferro Sanol Duodenal 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.

Ferro Sanol Duodenal 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 Ferro Sanol Duodenal, who were off intravenous Ferro Sanol Duodenal 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 Ferro Sanol Duodenal treated population showed a greater increase in hemoglobin and hematocrit than did patients in the historical control population. See Table 2.

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

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