CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Feraheme consists of superparamagnetic iron oxide that is coated with carbohydrate shell, which helps to isolate the bioactive iron from plasma components until the iron-carbohydrate complex enters the reticuloendothelial system macrophages of the liver, spleen and bone marrow. The iron is released from the iron-carbohydrate complex within vesicles in the macrophages. Iron then either enters the intracellular storage iron pool (e.g., ferritin) or is transferred to plasma transferrin for transport to erythroid precursor cells for incorporation into hemoglobin.. 12.2 Pharmacodynamics. Cardiac ElectrophysiologyIn randomized, positive- and placebo-controlled, parallel-group study, healthy subjects received supratherapeutic regimen of Feraheme (1.02 given as two 510 mg doses within 24 hours), placebo or single dose of 400 mg moxifloxacin (positive control). Results demonstrated no effect of Feraheme on QT interval durations. No clinically meaningful effect of Feraheme on heart rate was observed.. 12.3 Pharmacokinetics. The pharmacokinetic (PK) behavior of Feraheme has been examined in healthy subjects and in patients with CKD stage 5D on hemodialysis. Feraheme exhibited dose-dependent, capacity-limited elimination from plasma with half-life of approximately 15 hours in humans. The clearance (CL) was decreased by increasing the dose of Feraheme. Volume of distribution (Vd) was consistent with plasma volume, and the mean maximum observed plasma concentration (Cmax) and terminal half-life (t1/2) values increased with dose. The estimated values of CL and Vd following two 510 mg doses of Feraheme administered intravenously within 24 hours were 69.1 mL/hr and 3.16 L, respectively. The Cmax and time of maximum concentration (tmax) were 206 mcg/mL and 0.32 hr, respectively. Rate of infusion had no influence on Feraheme PK parameters. No gender differences in Feraheme PK parameters were observed. Feraheme is not removed by hemodialysis.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1Iron Deficiency Anemia in Patients Who Are Intolerant to Oral Iron or Have Had Unsatisfactory Response to Oral Iron IDA-301 Trial (referred to as IDA Trial 1) (NCT 01114139), IDA-302 Trial (referred to as IDA Trial 2) (NCT 01114204) and IDA-304 Trial (referred to as IDA Trial 3) (NCT 02694978)The safety and efficacy of Feraheme in patients with iron deficiency anemia, regardless of etiology and history of unsatisfactory oral iron therapy or in whom oral iron could not be used, were assessed in two randomized, controlled clinical trials (IDA Trial and 2) with Feraheme administered as rapid intravenous injection (prior method of administration no longer approved). In IDA Trial 1, patients were randomized to treatment with Feraheme or placebo. In IDA Trial 2, patients were randomized to treatment with Feraheme or iron sucrose. Feraheme (510 mg) and placebo were administered as two intravenous single dose injections over 3-8 days, and iron sucrose (200 mg) was administered as intravenous injections or infusions over period of 14 days.In IDA Trial 1, the mean age of patients was 45 years (range, 18 to 91); 89% were female; 56% were Caucasian, 25% were Black, 16% were Asian, and 3% were other races. In IDA Trial 2, the mean age of patients was 48 years (range, 18 to 89); 83% were female; 84% were Caucasian, 11% were Asian, 1% were Black, and 4% were other races.Table shows changes from baseline to Week in hemoglobin and transferrin saturation in IDA Trial and 2.Table 3:Changes from Baseline to Week in Hemoglobin (Hgb) and Transferrin Saturation in IDA Trial and (Intent to Treat Population) p<=0.001 for main efficacy endpointENDPOINTIDA Trial 1IDA Trial 2FerahemeN 608PlaceboN 200FerahemeN 406Iron SucroseN 199Baseline Hgbmean (SD), g/dL8.9 (0.9)8.8 (0.9)8.9 (0.9)8.8 (1.0)Proportion of patients with Hgb Increase of >=2.0 g/dL at any time from Baseline toWeek 5, %81.15.584.081.4 Treatment Difference (%, 95% CI)75.6 (71.2, 80.0)2.6(-3.9, 9.1)Mean change in Hgb from Baseline to Week 5mean (SD), g/dL2.6 (1.5)0.1 (0.9)2.9 (1.6)2.7 (1.3)Proportion of patients with Hgb >=12 g/dL at any time from Baseline to Week 5, %50.53.066.748.2Baseline TSATmean (SD) %7.0 (12.9)5.4 (4.9)6.1 (9.9)5.5 (10.3)Mean change in TSAT from Baseline to Week 5mean (SD), 11.4 (15.1)0.4 (5.8)15.7 (16.8)11.9 (14.4)In IDA Trial 1, fatigue-related symptoms and impacts were assessed using patient reported outcome instrument, FACIT-Fatigue (score range from to 52 with higher scores indicating less fatigue). After weeks, Feraheme-treated patients reported greater improvement from baseline in the fatigue score (+11.7 +- 11.73 points) than did patients in the placebo arm (+6.8 +- 9.51 points) with treatment difference of 4.9 (95% CI: 3.08-6.71) points.The safety of Feraheme in IDA patients with history of unsatisfactory oral iron therapy or in whom oral iron could not be used was also assessed in another randomized, multicenter, double-blind safety clinical trial (IDA Trial 3). Patients were randomized in 1:1 ratio to either two infusions of 510 mg (1.020 g) of Feraheme (n=997) or two infusions of 750 mg (1.500 g) of ferric carboxymaltose (FCM) (n=1000). Both IV irons were infused over period of at least 15 minutes. Most patients received their second infusion of Feraheme or FCM 7(+1) days after the first infusion. This study included patients with any etiology of IDA including CKD excluding dialysis-dependent CKD.In IDA Trial 3, the mean age of patients was 55 years (range, 18 to 96); 76% were female; 71% were Caucasian, 24% were Black, 3% were Asian, and 2% were other races. The study met the primary endpoint to demonstrate non-inferiority to FCM with respect to the percentage of patients who experienced moderate-to-severe hypersensitivity reactions (including anaphylaxis) or moderate-to-severe hypotension (Feraheme: 0.6%; FCM: 0.7%; treatment difference: -0.1%; exact 95% confidence interval: -0.91% to +0.70%).Table shows the mean increase from baseline to week in hemoglobin (Hgb) per treatment (Feraheme x 510 mg; FCM x 750 mg) and per gram of iron administered (Feraheme 1.020 g; FCM 1.500 g) in IDA Trial 3.

These trials also included an uncontrolled, follow-up phase in which patients with persistent iron deficiency anemia could receive two additional 510 mg intravenous injections of Feraheme. The major efficacy results from the controlled phase of each study are shown in Table 5.In all three trials, patients with CKD and iron deficiency anemia were randomized to treatment with Feraheme or oral iron. Feraheme was administered as two 510 mg undiluted intravenous injections and oral iron (ferrous fumarate) was administered as total daily dose of 200 mg elemental iron daily for 21 days. The major trial outcomes assessed the change in hemoglobin from baseline to Day 35. CKD Trial and enrolled patients with non-dialysis dependent CKD and CKD Trial enrolled patients who were undergoing hemodialysis. In CKD Trial 1, the mean age of patients was 66 years (range, 23 to 95); 60% were female; 65% were Caucasian, 32% were Black, and 2% were other races. In the Feraheme and oral iron groups, 42% and 44% of patients, respectively, were receiving erythropoiesis stimulating agents (ESAs) at baseline. In CKD Trial 2, the mean age of patients was 65 years (range, 31 to 96); 61% were female; 58% were Caucasian, 35% were Black, and 7% were other races. In the Feraheme and oral iron groups, 36% and 43% of patients, respectively, were receiving ESAs at baseline.In CKD Trial 3, the mean age of patients was 60 years (range, 24 to 87); 43% were female; 34% were Caucasian, 59% were Black, and 7% were other races. All patients were receiving ESAs.Table shows the Baseline and mean change to Day 35 in hemoglobin (Hgb, g/dL), transferrin saturation (TSAT, %) and ferritin (ng/mL) in each treatment group for Trial 1, 2, and 3.Table 5:Changes from Baseline to Day 35 in Hemoglobin (Hgb), Transferrin Saturation and Ferritin (Intent to Treat Population) in CKD Trials 1, and p<=0.001 for main efficacy endpointENDPOINTCKD Trial 1Non-DialysisCKD Trial 2Non-DialysisCKD Trial 3DialysisFeraheme = 226 Oral IronN 77Feraheme = 228 Oral IronN 76 Feraheme = 114 Oral IronN 116 Baseline Hgbmean (SD), g/dL9.9 (0.8)9.9 (0.7)10.0 (0.7)10.0 (0.8)10.6 (0.7)10.7(0.6)Hgb change from Baseline at Day 35 mean (SD), g/dL1.2 (1.3)0.5(1.0)0.8 (1.2)0.2 (1.0)1.0(1.1)0.5 (1.1)Baseline TSAT mean (SD), 9.8 (5.4)10.4 (5.2)11.3 (6.1)10.1 (5.5)15.7(7.2)15.9 (6.3)TSAT change from Baseline at Day 35 mean (SD), %9.2 (9.4)0.3 (4.7)9.8 (9.2)1.3 (6.4)6.4 (12.6)0.6 (8.3)Baseline ferritin mean (SD), ng/mL 123.7 (125.4)146.2 (136.3)146.1 (173.6)143.5 (144.9)340.5 (159.1) 357.6 (171.7) Ferritin change from Baseline at Day 35 mean (SD), ng/mL 300.7 (214.9) 0.3 (82.0)381.7 (278.6)6.9 (60.1)233.9 (207.0) -59.2 (106.2)Following completion of the controlled phase of each of the Phase trials, patients who were iron deficient and anemic could receive two additional 510 mg intravenous injections of Feraheme for total cumulative dose of 2.04 g. Overall, 69 patients received two additional 510 mg intravenous injections of Feraheme, and on Day 35 following these additional injections, the majority of these patients (70%) experienced an increase in hemoglobin and iron parameters (TSAT and ferritin). The mean change (+-SD) in hemoglobin level from the retreatment baseline for patients with an increase in hemoglobin was 0.86 (+- 0.68) g/dL and was 0.5 (+- 0.8) g/dL for all patients.In randomized, controlled clinical trial of 162 IDA patients with CKD (92 Non-Dialysis and 70 on Dialysis), mean change in hemoglobin from Baseline to Week was 0.71 +-1.03 g/dL for Feraheme-treated patients and 0.61 +-0.97 g/dL for iron sucrose-treated patients.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.In clinical studies, 3,968 subjects were exposed to Feraheme. Of these subjects 31% were male and the median age was 54 years (range of 18 to 96 years).The data described below reflect exposure to Feraheme in 997 patients exposed to 1.02 course of ferumoxytol administered as two 510 mg intravenous (IV) doses: 992 subjects (99.5%) received at least complete dose of ferumoxytol and 946 subjects (94.9%) received complete doses. The mean cumulative IV Iron exposure was 993.80 +-119.085 mg.The safety of Feraheme was studied in randomized, multicenter, double-blind clinical trial in patients with IDA (IDA Trial 3), [see Clinical Studies (14.1)]. In this trial, patients were randomized to two intravenous infusions of 510 mg (1.02 g) of Feraheme (n=997), or two intravenous infusions of 750 mg (1.500 g) of ferric carboxymaltose (FCM) (n=1000). Both intravenous irons were infused over period of at least 15 minutes. Most patients received their second infusion of Feraheme and FCM 7(+1) days after Dose 1.The mean (SD) age of the study population (N=1997) was 55.2 (17.16) years. The majority of patients were female (76.1%), white (71.4%) and non-Hispanic (81.8%). The mean (SD) hemoglobin at baseline for all patients was 10.4 (1.5) g/dl.Serious adverse events were reported in 3.6% (71/1997) of ferumoxytol- and FCM- treated patients. The most common (>=2 subjects) serious AEs reported in Feraheme-treated patients were syncope, gastroenteritis, seizure, pneumonia, hemorrhagic anemia, and acute kidney injury. In FCM-treated patients the most common (>=2 subjects) serious AEs were syncope, cardiac failure congestive, angina pectoris, and atrial fibrillation.Adverse reactions related to Feraheme and reported by >=1% of Feraheme-treated patients in IDA Trial are listed in Table 1.

Most patients received their second Feraheme injection to days after the first injection. Adverse reactions related to Feraheme and reported by >= 1% of Feraheme-treated patients in these trials were similar to those seen in Trial 3.In Trials and 2, adverse reactions leading to treatment discontinuation and occurring in >= Feraheme-treated patients included hypersensitivity (0.6%), hypotension (0.3%), and rash (0.2%).In addition, total of 634 subjects enrolled in and completed participation in Phase open label extension study. Of these, 337 subjects met IDA treatment criteria and received Feraheme. Adverse reactions following this repeat Feraheme dosing were generally similar in type and frequency to those observed after the first two intravenous injections.Across three randomized clinical trials in patients with IDA and CKD (CKD Trials 1, 2, and 3), [see Clinical Studies (14.2)], total of 605 patients were exposed to two injections of 510 mg of Feraheme and total of 280 patients were exposed to 200 mg/day of oral iron for 21 days. Most patients received their second Feraheme injection to days after the first injection.Adverse reactions related to Feraheme and reported by >= 1% of Feraheme-treated patients in the CKD randomized clinical trials are listed in Table . Diarrhea (4%), constipation (2.1%) and hypertension (1%) have also been reported in Feraheme-treated patients.Table 2:Adverse Reactions to Feraheme Reported in >=1% of Patients with IDA and CKD Trials 1, and 3Adverse ReactionsFeraheme2 510 mg(n 605)%Oral Iron (n 280)%Nausea3.17.5Dizziness2.61.8Hypotension2.50.4Peripheral Edema23.2Headache1.82.1Edema1.51.4Vomiting1.55Abdominal Pain1.31.4Chest Pain1.30.7Cough1.31.4Pruritus1.20.4Pyrexia10.7Back Pain10Muscle Spasms11.4Dyspnea11.1Rash10.4In these clinical trials in patients with IDA and CKD, adverse reactions leading to treatment discontinuation and occurring in >= Feraheme-treated patients included hypotension (0.4%), chest pain (0.3%), and dizziness (0.3%).Following completion of the controlled phase of the trials, 69 patients received two additional 510 mg intravenous injections of Feraheme (for total cumulative dose of 2.04 g). Adverse reactions following this repeat Feraheme dosing were similar in character and frequency to those observed following the first two intravenous injections.. 6.2 Postmarketing Experience. Because adverse reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.The following serious adverse reactions have been reported from the post-marketing experience with Feraheme: fatal, life-threatening, and serious anaphylactic-type reactions, cardiac/cardiorespiratory arrest, clinically significant hypotension, syncope, unresponsiveness, loss of consciousness, tachycardia/rhythm abnormalities, angioedema, ischemic myocardial events, congestive heart failure, pulse absent, and cyanosis. These adverse reactions have usually occurred within 30 minutes after the administration of Feraheme. Reactions have occurred following the first dose or subsequent doses of Feraheme.

DOSAGE & ADMINISTRATION SECTION.

2 DOSAGE AND ADMINISTRATION. The recommended dose of Feraheme is an initial 510 mg dose followed by second 510 mg dose to days later. Administer Feraheme as an intravenous infusion in 50-200 mL 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP over at least 15 minutes. Administer while the patient is in reclined or semi-reclined position.Feraheme does not contain antimicrobial preservatives. Discard unused portion. Feraheme, when added to intravenous infusion bags containing either 0.9% Sodium Chloride Injection, USP (normal saline), or 5% Dextrose Injection, USP, at concentrations of 2-8 mg elemental iron per mL, should be used immediately but may be stored at controlled room temperature (25C +- 2C) for up to hours or refrigerated (2-8 C) for up to 48 hours.The dosage is expressed in terms of mg of elemental iron, with each mL of Feraheme containing 30 mg of elemental iron. Evaluate the hematologic response (hemoglobin, ferritin, iron and transferrin saturation) at least one month following the second Feraheme infusion. The recommended Feraheme dose may be readministered to patients with persistent or recurrent iron deficiency anemia.For patients receiving hemodialysis, administer Feraheme once the blood pressure is stable and the patient has completed at least one hour of hemodialysis. Monitor for signs and symptoms of hypotension following each Feraheme infusion.Allow at least 30 minutes between administration of Feraheme and administration of other medications that could potentially cause serious hypersensitivity reactions and/or hypotension, such as chemotherapeutic agents or monoclonal antibodies.Inspect parenteral drug products visually for the absence of particulate matter and discoloration prior to administration.. The recommended dose of Feraheme is an initial 510 mg dose followed by second 510 mg dose to days later. (2)Administer Feraheme as an intravenous infusion in 50-200 mL 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP over at least 15 minutes (2). The recommended dose of Feraheme is an initial 510 mg dose followed by second 510 mg dose to days later. (2). Administer Feraheme as an intravenous infusion in 50-200 mL 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP over at least 15 minutes (2).

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryLimited available data with ferumoxytol use in pregnant women are insufficient to inform drug associated risk of adverse developmental outcomes. There are risks to the mother and fetus associated with untreated iron deficiency anemia (IDA) in pregnancy as well as risks to the fetus associated with maternal severe hypersensitivity reactions (see Clinical Considerations ). In animal studies, administration of ferumoxytol to pregnant rabbits during organogenesis caused adverse developmental outcomes including fetal malformations and decreased fetal weights at maternally toxic doses of times the estimated human daily dose.The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.Clinical ConsiderationsDisease-associated maternal and/or embryo/fetal riskUntreated iron deficiency anemia (IDA) in pregnancy is associated with adverse maternal outcomes such as post-partum anemia. Adverse pregnancy outcomes associated with IDA include increased risk for preterm delivery and low birth weight.Fetal/Neonatal adverse reactionsSevere adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with parenteral iron products (such as Feraheme) which may cause fetal bradycardia, especially during the second and third trimester.DataAnimal DataAdministration of ferumoxytol during organogenesis, at doses of 31.6 mg Fe/kg/day in rats and 16.5 mg Fe/kg/day in rabbits, did not result in maternal or fetal effects. These doses are approximately times the estimated human daily dose based on body surface area. In rats, administration of ferumoxytol during organogenesis at maternally toxic dose of 100 mg Fe/kg/day, approximately times the estimated human daily dose based on body surface area, caused decrease in fetal weights. In rabbits, administration of ferumoxytol during organogenesis at maternally toxic dose of 45 mg Fe/kg/day, approximately times the estimated human daily dose based on body surface area, was associated with external and soft tissue fetal malformations and decreased fetal weights.

SPL UNCLASSIFIED SECTION.

5.1 Serious Hypersensitivity Reactions. Fatal and serious hypersensitivity reactions including anaphylaxis, presenting with cardiac/ cardiorespiratory arrest, clinically significant hypotension, syncope, or unresponsiveness have occurred in patients receiving Feraheme. Other adverse reactions potentially associated with hypersensitivity have occurred (pruritus, rash, urticaria, and wheezing). These reactions have occurred following the first dose or subsequent doses in patients in whom previous Feraheme dose was tolerated.Patients with history of multiple drug allergies may have greater risk of anaphylaxis with parenteral iron products. Carefully consider the potential risks and benefits before administering Feraheme to these patients. Only administer Feraheme as an intravenous infusion over at least 15 minutes and only when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions. Closely observe patients for signs and symptoms of hypersensitivity including monitoring of blood pressure and pulse during and after Feraheme administration for at least 30 minutes and until clinically stable following completion of each infusion [see Adverse Reactions (6.2)]. In clinical study in patients with IDA, regardless of etiology, hypersensitivity reactions were reported in 0.4% (4/997) of subjects receiving Feraheme administered as intravenous infusion over at least 15 minutes. These included one patient with severe hypersensitivity reaction and three patients with moderate hypersensitivity reactions.In clinical studies predominantly in patients with IDA and CKD, serious hypersensitivity reactions were reported in 0.2% (4/1,806) of subjects receiving Feraheme (administered as rapid intravenous injection prior method of administration no longer approved). Other adverse reactions potentially associated with hypersensitivity (e.g., pruritus, rash, urticaria or wheezing) were reported in 3.5% (63/1,806) of these subjects.In the post-marketing experience, fatal and serious anaphylactic type reactions presenting with cardiac/ cardiorespiratory arrest, clinically significant hypotension, syncope, and unresponsiveness have been reported. Elderly patients with multiple or serious co-morbidities who experience hypersensitivity reactions and/or hypotension following administration of Feraheme may have more severe outcomes [see Boxed Warning, Adverse Reactions (6.2) and Use in Specific Populations (8.5) ].

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Risk SummaryLimited available data with ferumoxytol use in pregnant women are insufficient to inform drug associated risk of adverse developmental outcomes. There are risks to the mother and fetus associated with untreated iron deficiency anemia (IDA) in pregnancy as well as risks to the fetus associated with maternal severe hypersensitivity reactions (see Clinical Considerations ). In animal studies, administration of ferumoxytol to pregnant rabbits during organogenesis caused adverse developmental outcomes including fetal malformations and decreased fetal weights at maternally toxic doses of times the estimated human daily dose.The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.Clinical ConsiderationsDisease-associated maternal and/or embryo/fetal riskUntreated iron deficiency anemia (IDA) in pregnancy is associated with adverse maternal outcomes such as post-partum anemia. Adverse pregnancy outcomes associated with IDA include increased risk for preterm delivery and low birth weight.Fetal/Neonatal adverse reactionsSevere adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with parenteral iron products (such as Feraheme) which may cause fetal bradycardia, especially during the second and third trimester.DataAnimal DataAdministration of ferumoxytol during organogenesis, at doses of 31.6 mg Fe/kg/day in rats and 16.5 mg Fe/kg/day in rabbits, did not result in maternal or fetal effects. These doses are approximately times the estimated human daily dose based on body surface area. In rats, administration of ferumoxytol during organogenesis at maternally toxic dose of 100 mg Fe/kg/day, approximately times the estimated human daily dose based on body surface area, caused decrease in fetal weights. In rabbits, administration of ferumoxytol during organogenesis at maternally toxic dose of 45 mg Fe/kg/day, approximately times the estimated human daily dose based on body surface area, was associated with external and soft tissue fetal malformations and decreased fetal weights. 8.2 Lactation. Risk SummaryThere are no data on the presence of ferumoxytol in human milk, the effects on the breastfed child, or the effects on milk production. Ferumoxytol has been detected in the milk of lactating rats. However, due to species-specific differences in lactation physiology, the clinical relevance of these data are not clear. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Feraheme and any potential adverse effects on the breastfed child from Feraheme or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and effectiveness of Feraheme in pediatric patients (less than 18 years old) have not been established.. 8.5 Geriatric Use. In controlled clinical trials, 833 patients >= 65 years of age were treated with Feraheme. No overall differences in safety and efficacy were observed between older and younger patients in these trials, but greater sensitivity of 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. Elderly patients with multiple or serious co-morbidities who experience hypersensitivity reactions and/or hypotension following administration of Feraheme may have more severe outcomes. The potential risks and benefits of Feraheme administration should be carefully considered in these patients [see Dosage and Administration (2), Warnings and Precautions (5.1), and Clinical Studies (14)].

Elderly patients with multiple or serious co-morbidities who experience hypersensitivity reactions and/or hypotension following administration of Feraheme may have more severe outcomes [see Boxed Warning, Adverse Reactions (6.2) and Use in Specific Populations (8.5) ].. 5.2 Hypotension. Feraheme may cause clinically significant hypotension. In clinical study with Feraheme in patients with IDA, regardless of etiology, moderate hypotension was reported in 0.2% (2/997) of subjects receiving Feraheme administered as intravenous infusion over at least 15 minutes.In clinical studies in patients with IDA and CKD, hypotension was reported in 1.9% (35/1,806) of subjects, including three patients with serious hypotensive reactions, who had received Feraheme as rapid intravenous injection (prior method of administration no longer approved).Hypotension has also been reported in the post-marketing experience [see Adverse Reactions (6.2)]. Monitor patients for signs and symptoms of hypotension following each Feraheme administration [see Dosage and Administration (2) and Warnings and Precautions (5.1)].. 5.3 Iron Overload. Excessive therapy with parenteral iron can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Regularly monitor the hematologic response during parenteral iron therapy [see Dosage and Administration (2)]. Do not administer Feraheme to patients with iron overload.In the 24 hours following administration of Feraheme, laboratory assays may overestimate serum iron and transferrin bound iron by also measuring the iron in the Feraheme complex.. 5.4 Magnetic Resonance (MR) Imaging Test Interference. Administration of Feraheme may transiently affect the diagnostic ability of MR imaging. Conduct anticipated MR imaging studies prior to the administration of Feraheme. Alteration of MR imaging studies may persist for up to months following the last Feraheme dose. If MR imaging is required within months after Feraheme administration, use T1- or proton density-weighted MR pulse sequences to minimize the Feraheme effects; MR imaging using T2-weighted pulse sequences should not be performed earlier than weeks after the administration of Feraheme. Maximum alteration of vascular MR imaging is anticipated to be evident for - days following Feraheme administration [see Clinical Pharmacology (12.3)].Feraheme will not interfere with X-ray, computed tomography (CT), positron emission tomography (PET), single photon emission computed tomography (SPECT), ultrasound or nuclear medicine imaging.
