Ferofast Syrup is indicated for the treatment of Ferofast Syrup deficiency anemia in patients with chronic kidney disease (CKD).
Ferofast Syrup is an Ferofast Syrup replacement product indicated for the treatment of Ferofast Syrup deficiency anemia in patients with chronic kidney disease (CKD). (1)
Ferofast Syrup must only be administered intravenously either by slow injection or by infusion. The dosage of Ferofast Syrup is expressed in mg of elemental Ferofast Syrup. Each mL contains 20 mg of elemental Ferofast Syrup.
|Adult patients||Hemodialysis Dependent-Chronic Kidney Disease (2.1)||100 mg slow intravenous injection or infusion|
|Non-Dialysis Dependent-Chronic Kidney Disease (NDD-CKD) (2.2)||200 mg slow intravenous injection or infusion|
|Peritoneal Dialysis Dependent-Chronic Kidney Disease (PDD-CKD) (2.3)||300 mg or 400 mg intravenous infusion|
|Pediatric patients||HDD-CKD (2.4), PDD-CKD or NDD-CKD (2.5)||0.5 mg/kg slow intravenous injection or infusion|
Administer Ferofast Syrup 100 mg undiluted as a slow intravenous injection over 2 to 5 minutes, or as an infusion of 100 mg diluted in a maximum of 100 mL of 0.9% NaCl over a period of at least 15 minutes, per consecutive hemodialysis session. Ferofast Syrup should be administered early during the dialysis session. The usual total treatment course of Ferofast Syrup is 1000 mg. Ferofast Syrup treatment may be repeated if Ferofast Syrup deficiency reoccurs.
Administer Ferofast Syrup 200 mg undiluted as a slow intravenous injection over 2 to 5 minutes or as an infusion of 200 mg in a maximum of 100 mL of 0.9% NaCl over a period of 15 minutes. Administer on 5 different occasions over a 14 day period. There is limited experience with administration of an infusion of 500 mg of Ferofast Syrup, diluted in a maximum of 250 mL of 0.9% NaCl, over a period of 3.5 to 4 hours on Day 1 and Day 14. Ferofast Syrup treatment may be repeated if Ferofast Syrup deficiency reoccurs.
Administer Ferofast Syrup in 3 divided doses, given by slow intravenous infusion, within a 28 day period: 2 infusions each of 300 mg over 1.5 hours 14 days apart followed by one 400 mg infusion over 2.5 hours 14 days later. Dilute Ferofast Syrup in a maximum of 250 mL of 0.9% NaCl. Ferofast Syrup treatment may be repeated if Ferofast Syrup deficiency reoccurs.
The dosing for Ferofast Syrup replacement treatment in pediatric patients with HDD-CKD has not been established.
For Ferofast Syrup maintenance treatment: Administer Ferofast Syrup at a dose of 0.5 mg/kg, not to exceed 100 mg per dose, every two weeks for 12 weeks given undiluted by slow intravenous injection over 5 minutes or diluted in 25 mL of 0.9% NaCl and administered over 5 to 60 minutes. Ferofast Syrup treatment may be repeated if necessary.
The dosing for Ferofast Syrup replacement treatment in pediatric patients with NDD-CKD or PDD-CKD has not been established.
For Ferofast Syrup maintenance treatment: Administer Ferofast Syrup at a dose of 0.5 mg/kg, not to exceed 100 mg per dose, every four weeks for 12 weeks given undiluted by slow intravenous injection over 5 minutes or diluted in 25 mL of 0.9% NaCl and administered over 5 to 60 minutes. Ferofast Syrup treatment may be repeated if necessary.
Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Ferofast Syrup. 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 Ferofast Syrup immediately. Monitor patients for signs and symptoms of hypersensitivity during and after Ferofast Syrup administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Ferofast Syrup when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Most reactions associated with intravenous Ferofast Syrup preparations occur within 30 minutes of the completion of the infusion .
Ferofast Syrup may cause clinically significant hypotension. Monitor for signs and symptoms of hypotension following each administration of Ferofast Syrup. Hypotension following administration of Ferofast Syrup may be related to the rate of administration and/or total dose administered .
Excessive therapy with parenteral Ferofast Syrup can lead to excess storage of Ferofast Syrup with the possibility of iatrogenic hemosiderosis. All adult and pediatric patients receiving Ferofast Syrup require periodic monitoring of hematologic and Ferofast Syrup parameters (hemoglobin, hematocrit, serum ferritin and transferrin saturation). Do not administer Ferofast Syrup to patients with evidence of Ferofast Syrup overload. Transferrin saturation (TSAT) values increase rapidly after intravenous administration of Ferofast Syrup sucrose; do not perform serum Ferofast Syrup measurements for at least 48 hours after intravenous dosing .
The following serious adverse reactions associated with Ferofast Syrup are described in other sections .

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 Adult Patients with CKD
The frequency of adverse reactions associated with the use of Ferofast Syrup 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 Ferofast Syrup 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 Ferofast Syrup therapy and were reported to be intolerant (defined as precluding further use of that Ferofast Syrup product). When these patients were treated with Ferofast Syrup there were no occurrences of adverse reactions that precluded further use of Ferofast Syrup .
Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)
In a randomized, open-label, dose-ranging trial for Ferofast Syrup maintenance treatment with Ferofast Syrup 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 Ferofast Syrup 0.5 mg/kg, 53% (25/47) of the patients receiving Ferofast Syrup 1.0 mg/kg, and 55% (26/47) of the patients receiving Ferofast Syrup 2.0 mg/kg.
A total of 5 (11%) subjects in the Ferofast Syrup 0.5 mg/kg group, 10 (21%) patients in the Ferofast Syrup 1.0 mg/kg group, and 10 (21%) patients in the Ferofast Syrup 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%).
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 Ferofast Syrup. 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 Ferofast Syrup 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 Ferofast Syrup injection. Reactions have occurred following the first dose or subsequent doses of Ferofast Syrup. 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.
Drug interactions involving Ferofast Syrup have not been studied. However, Ferofast Syrup may reduce the absorption of concomitantly administered oral Ferofast Syrup preparations.
Pregnancy Category B
There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Ferofast Syrup sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Ferofast Syrup and revealed no evidence of harm to the fetus due to Ferofast Syrup sucrose. Because animal reproductive studies are not always predictive of human response, Ferofast Syrup should be used during pregnancy only if clearly needed.
It is not known whether Ferofast Syrup sucrose is excreted in human milk. Ferofast Syrup sucrose is secreted into the milk of lactating rats. Because many drugs are excreted in human milk, caution should be exercised when Ferofast Syrup is administered to a nursing woman.
Safety and effectiveness of Ferofast Syrup for Ferofast Syrup replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.
Safety and effectiveness of Ferofast Syrup for Ferofast Syrup maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Ferofast Syrup 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 ]
Ferofast Syrup has not been studied in patients younger than 2 years of age.
In a country where Ferofast Syrup 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 Ferofast Syrup, several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Ferofast Syrup or any other drugs could be established.
Clinical studies of Ferofast Syrup 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 Ferofast Syrup, 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 Ferofast Syrup in humans. Excessive dosages of Ferofast Syrup may lead to accumulation of Ferofast Syrup in storage sites potentially leading to hemosiderosis. Do not administer Ferofast Syrup to patients with Ferofast Syrup overload.
Toxicities in single-dose studies in mice and rats, at intravenous Ferofast Syrup 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.
Ferofast Syrup (iron sucrose injection, USP), an Ferofast Syrup replacement product, is a brown, sterile, aqueous, complex of polynuclear Ferofast Syrup (III)-hydroxide in sucrose for intravenous use. Ferofast Syrup 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 Ferofast Syrup polymerization and m is the number of sucrose molecules associated with the Ferofast Syrup (III)-hydroxide.
Each mL contains 20 mg elemental Ferofast Syrup as Ferofast Syrup sucrose in water for injection. Ferofast Syrup is available in 10 mL single-use vials (200 mg elemental Ferofast Syrup per 10 mL), 5 mL single-use vials (100 mg elemental Ferofast Syrup per 5 mL), and 2.5 mL single-use vials (50 mg elemental Ferofast Syrup 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.
Ferofast Syrup is an aqueous complex of poly-nuclear Ferofast Syrup -hydroxide in sucrose. Following intravenous administration, Ferofast Syrup is dissociated into Ferofast Syrup and sucrose and the Ferofast Syrup is transported as a complex with transferrin to target cells including erythroid precursor cells. The Ferofast Syrup in the precursor cells is incorporated into hemoglobin as the cells mature into red blood cells.
Following intravenous administration, Ferofast Syrup is dissociated into Ferofast Syrup and sucrose. In 22 patients undergoing hemodialysis and receiving erythropoietin (recombinant human erythropoietin) therapy treated with Ferofast Syrup sucrose containing 100 mg of Ferofast Syrup, three times weekly for three weeks, significant increases in serum Ferofast Syrup and serum ferritin and significant decreases in total Ferofast Syrup binding capacity occurred four weeks from the initiation of Ferofast Syrup sucrose treatment.
In healthy adults administered intravenous doses of Ferofast Syrup, its Ferofast Syrup 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 Ferofast Syrup component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Ferofast Syrup containing 100 mg of Ferofast Syrup labeled with 52Fe/59Fe in patients with Ferofast Syrup deficiency showed that a significant amount of the administered Ferofast Syrup is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Ferofast Syrup trapping compartment.
Following intravenous administration of Ferofast Syrup, Ferofast Syrup sucrose is dissociated into Ferofast Syrup and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Ferofast Syrup containing 1,510 mg of sucrose and 100 mg of Ferofast Syrup in 12 healthy adults, 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Ferofast Syrup 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 Ferofast Syrup sucrose containing 500 to 700 mg of Ferofast Syrup in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Ferofast Syrup was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Ferofast Syrup have not been studied.
Pharmacokinetics in Pediatric Patients
In a single-dose PK study of Ferofast Syrup, patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Ferofast Syrup at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Ferofast Syrup, the half-life of total serum Ferofast Syrup 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.
Ferofast Syrup is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Ferofast Syrup sucrose in the dialysate fluid was below the levels of detection of the assay (less than 2 parts per million).
Carcinogenicity studies have not been performed with Ferofast Syrup sucrose.
Ferofast Syrup sucrose was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Ferofast Syrup sucrose was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or in the in vivo mouse micronucleus assay.
Ferofast Syrup sucrose at intravenous doses up to 15 mg/kg/day of elemental Ferofast Syrup (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.
Five clinical trials involving 647 adult patients and one clinical trial involving 131 pediatric patients were conducted to assess the safety and efficacy of Ferofast Syrup.
Study A was a multicenter, open-label, historically-controlled study in 101 patients with HDD-CKD (77 patients with Ferofast Syrup treatment and 24 in the historical control group) with Ferofast Syrup deficiency anemia. Eligibility criteria for Ferofast Syrup 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.
Ferofast Syrup 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 Ferofast Syrup, who were off intravenous Ferofast Syrup 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 Ferofast Syrup 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.
|End of treatment||2 week follow-up||5 week follow-up|
|Ferofast Syrup (n=69||Historical Control (n=18)|| Ferofast Syrup |
| Historical Control |
| Ferofast Syrup |
| Historical |
|Hemoglobin (g/dL)||1.0 ± 0.12**||0.0 ± 0.21||1.3 ± 0.14**||-0.6 ± 0.24||1.2 ± 0.17*||-0.1 ± 0.23|
|Hematocrit (%)||3.1 ± 0.37**||-0.3 ± 0.65||3.6 ± 0.44**||-1.2 ± 0.76||3.3 ± 0.54||0.2 ± 0.86|
Serum ferritin increased at endpoint of study from baseline in the Venofer-treated population (165.3 ± 24.2 ng/mL) compared to the historical control population (-27.6 ± 9.5 ng/mL). Transferrin saturation also increased at endpoint of study from baseline in the Venofer-treated population (8.8 ± 1.6%) compared to this historical control population (-5.1 ± 4.3%).
Study B was a multicenter, open label study of Ferofast Syrup in 23 patients with Ferofast Syrup deficiency and HDD-CKD who had been discontinued from Ferofast Syrup 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.
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 Ferofast Syrup. Exclusion criteria were similar to those in studies A and B. Ferofast Syrup was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Ferofast Syrup 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.
Study D was a randomized, open-label, multicenter, active-controlled study of the safety and efficacy of oral Ferofast Syrup versus Ferofast Syrup 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 Ferofast Syrup (325 mg ferrous sulfate three times daily for 56 days); or Ferofast Syrup (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 Ferofast Syrup 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 Ferofast Syrup group.
A statistically significantly greater proportion of Ferofast Syrup subjects (35/79; 44.3%) compared to oral Ferofast Syrup subjects (23/82; 28%) had an increase in hemoglobin ≥ 1 g/dL at anytime during the study (p = 0.03).
Study E was a randomized, open-label, multicenter study comparing patients with PDD-CKD receiving an erythropoietin and intravenous Ferofast Syrup to patients with PDD-CKD receiving an erythropoietin alone without Ferofast Syrup 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 Ferofast Syrup or Ferofast Syrup (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 Ferofast Syrup / 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 Ferofast Syrup / 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 Ferofast Syrup / 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%).
Study F was a randomized, open-label, dose-ranging study for Ferofast Syrup 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 Ferofast Syrup (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 Ferofast Syrup once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Ferofast Syrup 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 Ferofast Syrup 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.
Ferofast Syrup is supplied sterile in 10 mL, 5 mL, and 2.5 mL single-use vials. Each 10 mL vial contains 200 mg elemental Ferofast Syrup, each 5 mL vial contains 100 mg elemental Ferofast Syrup, and each 2.5 mL vial contains 50 mg elemental Ferofast Syrup.
