3 DOSAGE FORMS AND STRENGTHS
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 Fera. 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 Fera immediately. Monitor patients for signs and symptoms of hypersensitivity during and after Fera administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Fera when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Most reactions associated with intravenous Fera preparations occur within 30 minutes of the completion of the infusion .
Fera may cause clinically significant hypotension. Monitor for signs and symptoms of hypotension following each administration of Fera. Hypotension following administration of Fera may be related to the rate of administration and/or total dose administered .
5.3 Fera Overload
Excessive therapy with parenteral Fera can lead to excess storage of Fera with the possibility of iatrogenic hemosiderosis. All adult and pediatric patients receiving Fera require periodic monitoring of hematologic and Fera parameters (hemoglobin, hematocrit, serum ferritin and transferrin saturation). Do not administer Fera to patients with evidence of Fera overload. Transferrin saturation (TSAT) values increase rapidly after intravenous administration of Fera sucrose; do not perform serum Fera measurements for at least 48 hours after intravenous dosing .
6 ADVERSE REACTIONS
The following serious adverse reactions associated with Fera are described in other sections .

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 Fera 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 Fera 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 Fera therapy and were reported to be intolerant (defined as precluding further use of that Fera product). When these patients were treated with Fera there were no occurrences of adverse reactions that precluded further use of Fera .
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 Fera maintenance treatment with Fera 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 Fera 0.5 mg/kg, 53% (25/47) of the patients receiving Fera 1.0 mg/kg, and 55% (26/47) of the patients receiving Fera 2.0 mg/kg.
A total of 5 (11%) subjects in the Fera 0.5 mg/kg group, 10 (21%) patients in the Fera 1.0 mg/kg group, and 10 (21%) patients in the Fera 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 Fera. 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 Fera 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 Fera injection. Reactions have occurred following the first dose or subsequent doses of Fera. 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 Fera have not been studied. However, Fera may reduce the absorption of concomitantly administered oral Fera preparations.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category B
Pregnancy Category B
There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Fera sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Fera and revealed no evidence of harm to the fetus due to Fera sucrose. Because animal reproductive studies are not always predictive of human response, Fera should be used during pregnancy only if clearly needed.
8.3 Nursing Mothers
It is not known whether Fera sucrose is excreted in human milk. Fera sucrose is secreted into the milk of lactating rats. Because many drugs are excreted in human milk, caution should be exercised when Fera is administered to a nursing woman.
8.4 Pediatric Use
Safety and effectiveness of Fera for Fera replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.
Safety and effectiveness of Fera for Fera maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Fera 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 ]
Fera has not been studied in patients younger than 2 years of age.
In a country where Fera 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 Fera, several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Fera or any other drugs could be established.
8.5 Geriatric Use
Clinical studies of Fera 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 Fera, 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.
No data are available regarding overdosage of Fera in humans. Excessive dosages of Fera may lead to accumulation of Fera in storage sites potentially leading to hemosiderosis. Do not administer Fera to patients with Fera overload.
Toxicities in single-dose studies in mice and rats, at intravenous Fera 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.
Fera (iron sucrose injection, USP), an Fera replacement product, is a brown, sterile, aqueous, complex of polynuclear Fera (III)-hydroxide in sucrose for intravenous use. Fera 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 Fera polymerization and m is the number of sucrose molecules associated with the Fera (III)-hydroxide.
Each mL contains 20 mg elemental Fera as Fera sucrose in water for injection. Fera is available in 10 mL single-use vials (200 mg elemental Fera per 10 mL), 5 mL single-use vials (100 mg elemental Fera per 5 mL), and 2.5 mL single-use vials (50 mg elemental Fera 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
Fera is an aqueous complex of poly-nuclear Fera -hydroxide in sucrose. Following intravenous administration, Fera is dissociated into Fera and sucrose and the Fera is transported as a complex with transferrin to target cells including erythroid precursor cells. The Fera in the precursor cells is incorporated into hemoglobin as the cells mature into red blood cells.
Following intravenous administration, Fera is dissociated into Fera and sucrose. In 22 patients undergoing hemodialysis and receiving erythropoietin (recombinant human erythropoietin) therapy treated with Fera sucrose containing 100 mg of Fera, three times weekly for three weeks, significant increases in serum Fera and serum ferritin and significant decreases in total Fera binding capacity occurred four weeks from the initiation of Fera sucrose treatment.
In healthy adults administered intravenous doses of Fera, its Fera 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 Fera component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Fera containing 100 mg of Fera labeled with 52Fe/59Fe in patients with Fera deficiency showed that a significant amount of the administered Fera is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Fera trapping compartment.
Following intravenous administration of Fera, Fera sucrose is dissociated into Fera and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Fera containing 1,510 mg of sucrose and 100 mg of Fera in 12 healthy adults, 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Fera 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 Fera sucrose containing 500 to 700 mg of Fera in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Fera was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Fera have not been studied.
Pharmacokinetics in Pediatric Patients
Pharmacokinetics in Pediatric Patients
In a single-dose PK study of Fera, patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Fera at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Fera, the half-life of total serum Fera 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.
Fera is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Fera 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 Fera sucrose.
Fera sucrose was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Fera sucrose was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or in the in vivo mouse micronucleus assay.
Fera sucrose at intravenous doses up to 15 mg/kg/day of elemental Fera (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 Fera.
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 Fera treatment and 24 in the historical control group) with Fera deficiency anemia. Eligibility criteria for Fera 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.
Fera 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 Fera, who were off intravenous Fera 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 Fera 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 Fera in 23 patients with Fera deficiency and HDD-CKD who had been discontinued from Fera 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 Fera. Exclusion criteria were similar to those in studies A and B. Fera was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Fera 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 Fera versus Fera 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 Fera (325 mg ferrous sulfate three times daily for 56 days); or Fera (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 Fera 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 Fera group.
A statistically significantly greater proportion of Fera subjects (35/79; 44.3%) compared to oral Fera 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 Fera to patients with PDD-CKD receiving an erythropoietin alone without Fera 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 Fera or Fera (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 Fera / 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 Fera / 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 Fera / 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: Fera 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 Fera 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 Fera (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 Fera once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Fera 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 Fera 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.
