Boxed warning. WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS Risk Associated with Intrathecal Use Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. EOVIST is not approved for intrathecal use [see Warnings and Precautions (5.1) ]. Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of EOVIST in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. The risk for NSF appears highest among patients with: Chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ), or Acute kidney injury. Screen…

Uses

1 INDICATIONS AND USAGE EOVIST is indicated for use in magnetic resonance imaging (MRI) of the liver to detect and characterize lesions in adult and pediatric patients, including term neonates, with known or suspected focal liver disease. EOVIST is a gadolinium-based contrast agent indicated for use in magnetic resonance imaging (MRI) of the liver to detect and characterize lesions in adult and pediatric patients, including term neonates, with known or suspected focal liver disease. ( 1 )

Dosage and administration

Recommended dose is 0.025 mmol/kg actual body weight (equivalent to 0.1 mL/kg) administered by intravenous injection at 1 mL/sec to 2 mL/sec. ( 2.1 ) See Full Prescribing Information for administration and imaging instructions. ( 2.2 , 2.3 ) 2.1 Recommended Dose The recommended dose of EOVIST for adult and pediatric patients, including term neonates, is 0.025 mmol/kg actual body weight (equivalent to 0.1 mL/kg) administered intravenously at a recommended rate of 1 mL/sec to 2 mL/sec. 2.2 Administration and Drug Handling EOVIST is for intravenous use only and must not be administered intrathecally [see Warnings and Precautions (5.1) ]. Use aseptic technique when preparing and administering EOVIST. Visually inspect EOVIST for particulate matter and discoloration prior to administration. Do not use the solution if it is discolored or if particulate matter is present. Use EOVIST immediately after obtaining appropriate dose from vial. Pierce the rubber stopper only once. Discard any unused portion of an EOVIST vial. Do not mix EOVIST with other medications and do not administer EOVIST in the same intravenous line simultaneously with other medications. Flush the intravenous cannula with 0.9% Sodium Chloride Injection after EOVIST injection. 2.3 Imaging Liver lesions are detected and characterized with pre-contrast MRI and EOVIST MRI obtained during dynamic and hepatocyte imaging phases. Perform a pre-contrast MRI, inject EOVIST, and begin dynamic imaging approximately 15 seconds to 25 seconds after completion of the injection. Dynamic imaging consists of the arterial, the porto-venous (approximately 60 seconds post-injection), and the blood equilibrium (approximately 120 seconds) phases. Begin the hepatocyte imaging phase approximately 20 minutes post-injection. Hepatocyte phase imaging may be performed up to 120 minutes post-injection. Elevated intrinsic levels of bilirubin (>3 mg/dL) or ferritin can reduce the hepatic contrast effect of EOVIST. Perform MR imaging no later than 60 minutes following EOVIST administration to patients with these laboratory abnormalities, including patients who have elevated ferritin levels due to hemodialysis [see Warnings and Precautions (5.8) and Use in Specific Populations (8.6 , 8.7) ]. Lesions with no or minimal hepatocyte function (cysts, metastases, and the majority of hepatocellular carcinomas) generally will not accumulate EOVIST. Well-differentiated hepatocellular carcinoma may contain functioning hepatocytes and can show some enhancement in the hepatocyte imaging phase. Additional clinical information is therefore needed to support a diagnosis of hepatocellular carcinoma.

Contraindications

4 CONTRAINDICATIONS EOVIST is contraindicated in patients with history of severe hypersensitivity reactions to EOVIST [see Warnings and Precautions (5.3) ] . History of severe hypersensitivity reaction to EOVIST ( 4 )

Warnings and precautions

Hypersensitivity Reactions: Anaphylactic and other hypersensitivity reactions with cardiovascular, respiratory and cutaneous manifestations, ranging from mild to severe reactions including shock can occur. Monitor patients closely for need of emergency cardiorespiratory support ( 5.3 ) Gadolinium Retention: Gadolinium is retained for months or years in brain, bone, and other organs. ( 5.4 ) 5.1 Risk Associated with Intrathecal Use Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of EOVIST have not been established with intrathecal use. EOVIST is not approved for intrathecal use [see Dosage and Administration (2.2) ]. 5.2 Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of EOVIST among these patients unless the diagnostic information is essential and not available with non-contrast enhanced MRI or other modalities. The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ) as well as patients with acute kidney injury. The risk appears lower for patients with chronic, moderate kidney disease (GFR 30 to 59 mL/min/1.73m 2 ) and little, if any, for patients with chronic, mild kidney disease (GFR 60 to 89 mL/min/1.73m 2 ). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. Report any diagnosis of NSF following EOVIST administration to Bayer HealthCare (1-888-842-2937) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Screen patients for acute kidney injury and other conditions that may reduce renal function. Features of acute kidney injury consist of rapid (over hours to days) and usually reversible decrease in kidney function, commonly in the setting of surgery, severe infection, injury or drug-induced kidney toxicity. Serum creatinine levels and estimated GFR may not reliably assess renal function in the setting of acute kidney injury. For patients at risk for chronically reduced renal function (for example, age > 60 years, diabetes mellitus or chronic hypertension), estimate the GFR through laboratory testing. Among the factors that may increase the risk for NSF are repeated or higher than recommended doses of a GBCA and degree of renal impairment at the time of exposure. Record the specific GBCA and the dose administrated to a patient. For patients at highest risk for NSF, do not exceed the recommended EOVIST dose and allow a sufficient period of time for elimination of the drug prior to any re-administration. For patients receiving hemodialysis, consider the prompt initiation of hemodialysis following the administration of a GBCA in order to enhance the contrast agent's elimination [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ]. The usefulness of hemodialysis in the prevention of NSF is unknown. 5.3 Hypersensitivity Reactions Anaphylactic and other hypersensitivity reactions with cardiovascular, respiratory and cutaneous manifestations, ranging from mild to severe, including shock have occurred following EOVIST administration. Most hypersensitivity reactions to EOVIST have occurred within half an hour after administration. Delayed reactions can occur up to several days after EOVIST administration [see Adverse Reactions (6.2) ] . Before EOVIST administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to EOVIST. EOVIST is contraindicated in patients with history of hypersensitivity reactions to EOVIST [see Contraindications (4) ]. Administer EOVIST only in situations where trained personnel and therapies are promptly available for the treatment of hypersensitivity reactions, including personnel trained in resuscitation. Observe patients for signs and symptoms of hypersensitivity reactions during and following EOVIST administration. 5.4 Gadolinium Retention Gadolinium is retained for months or years in several organs. The highest concentrations (nanomoles per gram of tissue) have been identified in the bone, followed by other organs (for example, brain, skin, kidney, liver, and spleen). The duration of retention also varies by tissue and is longest in bone. Linear GBCAs cause more retention than macrocyclic GBCAs. At equivalent doses, gadolinium retention varies among the linear agents with gadodiamide causing greater retention than other linear agents such as gadoxetate disodium and gadobenate dimeglumine. Retention is lowest and similar among the macrocyclic GBCAs such as gadoterate meglumine, gadobutrol, gadoteridol, and gadopiclenol. Consequences of gadolinium retention in the brain have not been established. Pathologic and clinical consequences of GBCA administration and retention in skin and other organs have been established in patients with impaired renal function [see Warnings and Precautions (5.2) ] . There are rare reports of pathologic skin changes in patients with normal renal function. Adverse events involving multiple organ systems have been reported in patients with normal renal function without an established causal link to gadolinium retention [see Adverse Reactions (6.2) ] . While clinical consequences of gadolinium retention have not been established in patients with normal renal function, certain patients might be at higher risk. These include patients requiring multiple lifetime doses, pregnant and pediatric patients, and patients with inflammatory conditions. Consider the retention characteristics of the agent when choosing a GBCA for these patients. Minimize repetitive GBCA imaging studies particularly closely spaced studies, when possible.

Side effects

The following clinically significant adverse reactions are discussed elsewhere in the labeling: Nephrogenic systemic fibrosis [see Warnings and Precautions (5.2) ] Hypersensitivity reactions [see Contraindications (4) and Warnings and Precautions (5.3) ] Most common adverse reactions (incidence ≥ 0.5%) are nausea, headache, feeling hot, dizziness, and back pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bayer HealthCare Pharmaceuticals Inc. at 1-888-84-BAYER (1-888-842-2937) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Adverse Reactions in Adults The safety of EOVIST was evaluated in 1,989 adult subjects who received EOVIST in clinical trials. Overall, 59% of the subjects were male, and the racial and ethnic distribution was 64% White, 22% Asian, 3% Hispanic or Latino, 2% Black or African American, and 0.5% other ethnic groups. The average age was 57 years (age range from 19 to 84 years). Table 1 lists adverse reactions that occurred in ≥ 0.1% of subjects who received the recommended dose of EOVIST in clinical trials. Table 1: Adverse Reactions Reported in ≥ 0.1% of Adult Subjects who Received EOVIST in Clinical Trials Adverse Reaction EOVIST n = 1,581 Rate (%) Nausea 1.1 Headache 1.1 Feeling hot 0.8 Dizziness 0.6 Back pain 0.6 Vomiting 0.4 Blood pressure increased 0.4 Injection site reactions (pain, burning, coldness, extravasation, irritation) 0.4 Dysgeusia 0.4 Paresthesia 0.3 Flushing 0.3 Parosmia 0.3 Pruritus (generalized, eye) 0.3 Rash 0.3 Respiratory disorders (dyspnea, respiratory distress) 0.2 Fatigue 0.2 Chest pain 0.1 Vertigo 0.1 Dry mouth 0.1 Chills 0.1 Feeling abnormal 0.1 Adverse reactions that occurred with a frequency of < 0.1% in subjects who received EOVIST include: tremor, akathisia, bundle branch block, palpitation, oral discomfort, salivary hypersecretion, maculopapular rash, hyperhidrosis, discomfort, and malaise. Elevation of serum iron values and serum bilirubin laboratory values were reported in < 1% of subjects after administration of EOVIST. The values did not exceed more than 3 times the baseline values and returned to baseline within 1 to 4 days. Adverse Reactions in Pediatric Patients In a study of EOVIST in 52 pediatric patients between 2 months of age and 18 years of age, no new safety signals were observed [see Use in Specific Populations (8.4) ]. 6.2 Postmarketing Experience The following additional adverse reactions have been identified during the postmarketing use of EOVIST or other GBCAs. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiac Disorders: Tachycardia Gastrointestinal Disorders: Acute pancreatitis with onset within 48 hours after GBCA administration General Disorders and Administration Site Conditions: Fatigue, asthenia, pain syndromes, and heterogeneous clusters of symptoms in the neurological, cutaneous, and musculoskeletal systems with variable onset and duration after GBCA administration [see Warnings and Precautions (5.4) ] Immune System Disorders: Hypersensitivity reactions (anaphylactic shock, hypotension, pharyngolaryngeal edema, urticaria, face edema, rhinitis, conjunctivitis, abdominal pain, hypoesthesia, sneezing, cough and pallor) Psychiatric Disorders: Restlessness Renal Disorders: Nephrogenic systemic fibrosis Respiratory, Thoracic, and Mediastinal Disorders: Acute respiratory distress syndrome, pulmonary edema Skin Disorders: Gadolinium associated plaques

Drug interactions

Serum Iron Test EOVIST contains caloxetate trisodium that can interfere with serum iron determination using complexometric methods (for example, ferrocene complexation method) and may result in falsely high or low values for up to 24 hours after the administration of EOVIST. Conduct serum iron tests either before or at least 24 hours following administration of EOVIST. Serum iron determination using complexometric methods (for example, ferrocene complexation method) may result in falsely high or low values for up to 24 hours. Conduct serum iron tests either before or at least 24 hours following administration. ( 7 )

Use in specific populations

Pregnancy: Use only if imaging is essential during pregnancy and cannot be delayed. ( 8.1 ) 8.1 Pregnancy Risk Summary GBCAs cross the placenta and result in fetal exposure. In human placental imaging studies, contrast was visualized in the placenta and fetal tissues after maternal GBCA administration. Based on animal studies, use of GBCAs during pregnancy may result in fetal gadolinium retention. Published epidemiological studies on the association between GBCAs and adverse fetal outcomes have reported inconsistent findings and have important methodological limitations (see Data ). In animal reproduction studies, no teratogenicity was observed with repeated daily intravenous administration of gadoxetate disodium to rats during organogenesis at doses up to 32 times the recommended single human dose; however, an increase in preimplantation loss was noted at doses 3.2 times the single human dose. Post implantation loss was observed with repeated daily intravenous administration of gadoxetate disodium to rabbits on gestation days 6 through 18 at doses 26 times the recommended single human dose (see Data ) . Because of the potential risks of gadolinium to the fetus, use EOVIST only if imaging is essential during pregnancy and cannot be delayed. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data Available data regarding exposure to GBCAs during pregnancy from published epidemiological studies are not sufficient to assess the risk of adverse fetal and neonatal effects that may be associated with GBCAs. A retrospective cohort study of over 1.4 million pregnancies in Ontario, Canada, comparing pregnant women who had a GBCA MRI to pregnant women who did not have an MRI, reported a higher occurrence of stillbirths and neonatal deaths in the group receiving GBCA MRI. Limitations of this study include a lack of comparison with non-contrast MRI and lack of information about the maternal indication for MRI. Another retrospective cohort study of over 11 million pregnancies in the Medicaid database found no increased risk of fetal or neonatal death or Neonatal Intensive Care Unit admission when comparing pregnancies exposed to GBCA MRI versus non-contrast MRI. These two retrospective studies assessed a limited number of potential pregnancy outcomes and did not evaluate the full spectrum of potential fetal risk. Animal Data Gadolinium Retention GBCAs administered to pregnant non-human primates (0.1 mmol/kg on gestational days 85 and 135) result in measurable gadolinium concentration in the offspring in bone, brain, skin, liver, kidney, and spleen for at least 7 months. GBCAs administered to pregnant mice (2 mmol/kg daily on gestational days 16 through 19) result in measurable gadolinium concentrations in the pups in bone, brain, kidney, liver, blood, muscle, and spleen at one month postnatal age. Reproductive Toxicology Animal reproductive and developmental toxicity studies were done in rats and rabbits. Gadoxetate disodium was not teratogenic when given intravenously during organogenesis to pregnant rats at doses up to 32 times the recommended single human dose (mmol/m 2 basis). However, an increase in preimplantation loss was noted at 3.2 times the human dose (mmol/m 2 basis). Compared to untreated controls, rates of post implantation loss and absorption increased and litter size decreased when pregnant rabbits received gadoxetate disodium at doses 26 times the recommended human single dose (mmol/m 2 basis). This occurred without evidence of maternal toxicity. Because pregnant animals received repeated daily doses of gadoxetate disodium, their overall exposure was significantly higher than that achieved with the standard single dose administered to humans. 8.2 Lactation Risk Summary There is no information regarding the presence of gadoxetate disodium in human milk, the effects of the drug in a breastfed infant, or the effects of the drug on milk production. However, published lactation data on other GBCAs report that 0.01 to 0.04% of the maternal gadolinium dose is present in breast milk and there is limited GBCA gastrointestinal absorption in the breastfed infant. In rat lactation studies with [ 153 Gd] gadoxetate disodium, less than 0.5% of the total administered radioactivity was transferred to the nursing pup (see Data ). Clinical Considerations A lactating woman may consider interrupting breastfeeding and pumping and discarding breast milk for up to 10 hours after EOVIST administration in order to minimize exposure to a breastfed infant. Data In lactating rats given 0.1 mmol/kg [ 153 Gd] gadoxetate disodium, less than 0.5% of the total administered radioactivity was transferred to the neonates via maternal milk, mostly within 2 hours. 8.4 Pediatric Use The safety and effectiveness of EOVIST for magnetic resonance imaging (MRI) of the liver to detect and characterize lesions have been established in pediatric patients, including term neonates. Use of EOVIST in this age group is supported by evidence from adequate and well-controlled studies in adults and an observational study in 52 pediatric patients between 2 months of age and 18 years of age who were referred for evaluation of suspected or known focal liver lesions. In this observational study, EOVIST improved border delineation and increased contrast of the primary lesion in the majority of patients when compared to non-contrast images [see Adverse Reactions (6.1) and Clinical Studies (14) ] . The safety and effectiveness of EOVIST have not been established in preterm neonates.

Pediatric use

8.4 Pediatric Use The safety and effectiveness of EOVIST for magnetic resonance imaging (MRI) of the liver to detect and characterize lesions have been established in pediatric patients, including term neonates. Use of EOVIST in this age group is supported by evidence from adequate and well-controlled studies in adults and an observational study in 52 pediatric patients between 2 months of age and 18 years of age who were referred for evaluation of suspected or known focal liver lesions. In this observational study, EOVIST improved border delineation and increased contrast of the primary lesion in the majority of patients when compared to non-contrast images [see Adverse Reactions (6.1) and Clinical Studies (14) ] . The safety and effectiveness of EOVIST have not been established in preterm neonates.

Geriatric use

8.5 Geriatric Use In clinical studies of EOVIST, 674 (34%) patients were 65 years of age and over, while 20 (1%) were 80 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences between the elderly and younger patients. In general, use of EOVIST in 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.

Overdosage

In case of inadvertent overdosage in patients with severely impaired renal and/or hepatic function, EOVIST can be partially removed by hemodialysis [see Clinical Pharmacology (12.3) ]. For additional overdose management recommendations, consider contacting the Poison Help line at 1-800-222-1222 or consulting a medical toxicologist.

Description

(gadoxetate disodium) injection is a paramagnetic gadolinium-based contrast agent for intravenous use. Gadoxetate disodium (Gd-EOB-DTPA) is a highly water-soluble, hydrophilic compound with a lipophilic moiety, the ethoxybenzyl group (EOB). EOB-DTPA forms a stable complex with the paramagnetic gadolinium ion with a thermodynamic stability of log KGdL=-23.46. The chemical name for gadoxetate disodium is (4S)-4-(4-Ethoxybenzyl)-3,6,9-tris(carboxylatomethyl)-3,6,9-triazaundecanedioic acid, gadolinium complex, disodium salt. Gadoxetate disodium has a molecular weight of 725.72 and an empirical formula of GdC 23 H 28 N 3 O 11 Na 2 . The structural formula of gadoxetate disodium is: EOVIST is a sterile, clear, colorless to pale yellow solution. Each mL contains 181.43 mg (0.25 mmol) of gadoxetate disodium (containing 0.25 mmol of gadolinium) and the following inactive ingredients: 1 mg of caloxetate trisodium, 1.21 mg of trometamol, hydrochloric acid and/or sodium hydroxide (for pH adjustment), and water for injection. EOVIST contains no antimicrobial preservative. Pertinent physiochemical properties of EOVIST are provided in Table 2. Table 2: Physicochemical Properties of EOVIST Parameter Value Osmolality at 37°C (Osm/kg H 2 O) 0.688 Viscosity at 37°C (cP) 1.19 Density at 37°C (g/mL) 1.088 pH 6.8-8 Chemical Structure

Mechanism of action

12.1 Mechanism of Action Gadoxetate is a paramagnetic molecule that develops a magnetic moment when placed in a magnetic field. The magnetic moment alters the relaxation rates of water protons in its vicinity in the body, leading to an increase in signal intensity (brightness) of tissues. Gadoxetate is selectively taken up by hepatocytes, resulting in increased signal intensity in liver tissue.

How supplied

How Supplied EOVIST (gadoxetate disodium) injection is supplied at a concentration of 0.25 mmol/mL of gadoxetate disodium as a clear and colorless to pale yellow solution available in the following strengths: 2.5 mmol/10 mL (2.5 mmol/mL) in single-dose vials, boxes of 5 (NDC 50419-320-05) 3.75 mmol/15 mL (2.5 mmol/mL) in single-dose vials, boxes of 5 (NDC 50419-320-15) Storage and Handling Store at 20°C to 25° C (68°F to 77° F); excursions permitted to 15°C to 30° C (59°F to 86°F) [see USP Controlled Room Temperature].

Storage

Storage and Handling Store at 20°C to 25° C (68°F to 77° F); excursions permitted to 15°C to 30° C (59°F to 86°F) [see USP Controlled Room Temperature].

Patient information

Advise the patient to read the FDA-approved patient labeling (Medication Guide). Nephrogenic Systemic Fibrosis Inform the patient that EOVIST may increase the risk for NSF among patients with impaired elimination of the drug and that NSF may result in fatal or debilitating fibrosis affecting the skin, muscle, and internal organs. Instruct the patients to contact their physician if they develop signs or symptoms of NSF following EOVIST administration, such as burning, itching, swelling, scaling, hardening and tightening of the skin; red or dark patches on the skin; stiffness in joints with trouble moving, bending or straightening the arms, hands, legs or feet; pain in the hip bones or ribs; or muscle weakness [see Warnings and Precautions (5.2) ] . Gadolinium Retention Advise patients that gadolinium is retained for months or years in brain, bone, skin, and other organs following EOVIST administration even in patients with normal renal function. The clinical consequences of retention are unknown. Retention depends on multiple factors and is greater following administration of linear GBCAs than following administration of macrocyclic GBCAs [see Warnings and Precautions (5.4) ]. Pregnancy Advise pregnant women of the potential risk of fetal exposure to EOVIST [see Use in Specific Populations (8.1) ] .
