Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the prescribing information: Nephrogenic systemic fibrosis [see Boxed Warning and Warnings and Precautions ( 5.1 )] Hypersensitivity reactions [see Contraindications ( 4 ) and Warnings and Precautions ( 5.2 )] The most commonly reported adverse reactions are nausea and taste perversion with an incidence ≥ 0.9% ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, Contact Bracco Diagnostics Inc. at 1-800-257-5181 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 practice. The adverse events described in this section were observed in clinical trials involving 3174 subjects (including 2896 adults and 278 pediatric subjects ages 0 to 17 years) exposed to ProHance. Approximately 48% of the subjects were men and ethnic distribution was 78% Caucasian, 6% Black, 3% Hispanic, 6% Asian, and 2% other. In 5% of the subjects, race was not reported. Average age was 47 years (range from 1 day to 91 years) and the exposure ranged from 0.03 to 0.3 mmol/kg. Overall, approximately 5.8% of subjects reported one or more adverse reactions during a follow-up period that ranged from 24 hours to 7 days after ProHance administration. Table 2 lists adverse reactions that occurred in ≥ 0.4% subjects who received ProHance. Table 2: More frequent adverse reactions in clinical trials Reaction Rate (%) N = 3174 Nausea 1.4% Dysgeusia 0.9% Headache 0.7% Dizziness 0.4% Urticaria 0.4% The following additional adverse events occurred in fewer than 0.4% of the subjects: General disorders and administration site conditions: Asthenia; chest discomfort, facial edema, feeling hot, injection site coldness, injection site erythema, injection site pain, injection site warmth, pain, pyrexia Cardiac: Angina pectoris, palpitations, atrio-ventricular block first degree Ear and labyrinth disorders: Ear discomfort, tinnitus Eye disorders: Eye pruritis, lacrimation increased Gastrointestinal disorders: Abdominal discomfort, abdominal pain, diarrhea, dry mouth, gingival pain, oral pruritis, swollen tongue, vomiting Infections and infestations: Gingivitis, rhinitis Investigations: Alanine aminotransferase increased, aspartate aminotransferase increased, blood chloride increased, blood pressure immeasurable, blood urea decreased, hemoglobin decreased, heart rate increased Metabolism and nutrition disorders: Decreased appetite, hypoglycemia Musculoskeletal and connective tissue disorders: Back pain, musculoskeletal stiffness Nervous system disorders: Formication, hypoesthesia, hypokinesia, lethargy, loss of consciousness, migraine, paresthesia, presyncope, seizure, syncope, taste disorder Psychiatric disorders: Anxiety, mental status changes Respiratory, thoracic and mediastinal disorders: Cough, dry throat, dyspnea, nasal discomfort, throat irritation Skin and subcutaneous tissue disorders: Hyperhidrosis, pruritis, rash, rash morbilliform Vascular disorders: Flushing, hypotension, peripheral coldness, vascular rupture, vasodilatation, vasospasm 6.2 Post-marketing Experience The following adverse reactions have been identified during post approval use of ProHance that were not observed in the clinical trials. 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. * Cases of acute renal failure have been reported in patients with pre-existing severe renal impairment. The following adverse drug reactions have also been reported: General Disorders and Administration Site Conditions: Adverse events with variable onset and duration have been reported after GBCA administration [see Warnings and Precautions ( 5.3 )]. These include fatigue, asthenia, pain syndromes, and heterogeneous clusters of symptoms in the neurological, cutaneous, and musculoskeletal systems.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Gadoteridol is a paramagnetic agent and, as such, develops a magnetic moment when placed in a magnetic field. The relatively large magnetic moment produced by the paramagnetic agent results in a relatively large local magnetic field, which can enhance the relaxation rates of water protons in the vicinity of the paramagnetic agent. In MRI, visualization of normal and pathologic brain tissue depends, in part, on variations in the radiofrequency signal intensity that occur with: 1) differences in proton density; 2) differences of the spin-lattice or longitudinal relaxation times (T1); and 3) differences in the spin-spin or transverse relaxation time (T2). When placed in a magnetic field, gadoteridol decreases T1 relaxation times in the target tissues. At recommended doses, the effect is observed with greatest sensitivity in the T1-weighted sequences. 12.2 Pharmacodynamics Gadoteridol affects proton relaxation times and consequently the MR signal. Signal intensity is affected by the dose and relaxivity of the gadoteridol molecule. Consistently, for all gadolinium based contrast agents, the relaxivity of gadoteridol decreases with the increase of the magnetic field strength used in clinical MRI (0.2 – 3.0T). Disruption of the blood-brain barrier or abnormal vascularity allows accumulation of gadoteridol in lesions such as neoplasms, abscesses, and subacute infarcts. The pharmacokinetics of gadoteridol in various lesions is not known. 12.3 Pharmacokinetics The pharmacokinetics of intravenously administered gadoteridol in normal subjects conforms to a two-compartment open model. Distribution After intravenous administration, gadoteridol is rapidly distributed in the extracellular space. The plasma distribution volume (mean ± SD) for the non-renally impaired adults was 0.205 ± 0.025 L/kg. It is unknown if protein binding of gadoteridol occurs in vivo . Following GBCA administration, gadolinium is present for months or years in brain, bone, skin, and other organs [see Warnings and Precautions ( 5.3 )]. Metabolism It is unknown if biotransformation or decomposition of gadoteridol occur in vivo . Elimination Gadoteridol is eliminated unchanged via the kidneys. The elimination half-life (mean ± SD) is about 1.57 ± 0.08 hours. Within 24 hours post-injection, 94.4 ± 4.8% of the dose is excreted in the urine. The renal and plasma clearance rates (1.41 ± 0.33 mL/ min/kg and 1.50 ± 0.35 mL/ min/kg, respectively) of gadoteridol are essentially identical, indicating no alteration in elimination kinetics on passage through the kidneys and that the drug is essentially cleared through the kidney. The volume of distribution (204 ± 58 mL/kg) is equal to that of extracellular water, and clearance is similar to that of substances which are subject to glomerular filtration. Specific Populations Gender Gender has no clinically relevant effect on the pharmacokinetics of gadoteridol. Geriatric There were 7 elderly subjects receiving 0.1 (n = 3) and 0.3 mmol/kg (n = 4) dose of ProHance. The clearance was slightly lower in elderly subjects as compared to non-elderly subjects. [see Use in Specific Populations ( 8.5 )] . Pediatric A population pharmacokinetic analysis incorporated data from 79 subjects, 45 males and 34 females. Among 79 subjects, 41 were healthy subjects including 28 pediatric subjects between 5 years and 15 years of age. The pediatric subjects received a single intravenous dose of 0.1 mmol/kg of ProHance. From population PK model, the mean C max was 0.66 ± 0.21 mmol/L in pediatric subjects 2 years to 6 years of age, 0.58 ± 0.06 mmol/L in pediatric subjects 6 years to 12 years of age, and 0.68 ± 0.12 mmol/L in adolescent subjects older than 12 years. The mean AUC 0-∞ was 0.74 ± 0.20 mmol/L⋅h in pediatric subjects 2 years to 6 years of age, 0.74 ± 0.09 mmol/L⋅h in pediatric subjects 6 years to 12 years of age, and 0.98 ± 0.09 mmol/L⋅h in adolescent subjects older than 12 years of age. The mean distribution half- life (t 1/2,alpha ) was 0.14 ± 0.04 hours in pediatric subjects 2 years to 6 years of age, 0.18 ± 0.07 hours in pediatric subjects 6 years to 12 years of age, and 0.20 ± 0.07 hours in adolescent subjects older than 12 years of age. The mean elimination half-life (t 1/2,beta ) was 1.32 ± 0.006 hours in pediatric subjects 2 years to 6 years, 1.32 ± 0.07 hours in pediatric subjects 6 years to 12 years of age, and 1.61 ± 0.19 hours in adolescent subjects older than 12 years of age. There was no significant gender-related difference in the pharmacokinetic parameters in the pediatric patients. Over 80% of the dose was recovered in urine for pediatric subjects after 10 hours. Pharmacokinetic simulations indicate similar half-life, AUC, and C max values for ProHance in pediatric subjects less than 2 years of age when compared to those reported for adults; no age-based dose adjustment is necessary for this pediatric population. Renal Impairment In patients with impaired renal function, the serum half-life of gadoteridol is prolonged. After intravenous injection of 0.1 mmol/kg, the elimination half-life of gadoteridol was 10.65 ± 0.60 hours in mild to moderately impaired patients (creatinine clearance 30 to 60 mL/min) and 9.10±0.26 hours in severely impaired patients not on dialysis (creatinine clearance 10 to 30 mL/min). The mean serum clearance of gadoteridol in patients with normal renal function was 116.14 ± 26.77 mL/min, compared to 37.2 ± 16.4 mL/min in patients with mild to moderate renal impairment and 16.0 ± 3.0 mL/min in patients with severe renal impairment. In patients with moderately and severely impaired renal function about 97% and 76% of the administered dose was recovered in the urine within 7 days and 14 days, respectively. For patients receiving hemodialysis, physicians may consider the prompt initiation of hemodialysis following the administration of ProHance in order to enhance the contrast agent’s elimination. Seventy- two percent (72%) of gadoteridol is removed from the body after the first dialysis, 91% after the second dialysis, and 98% after the third dialysis session.

Information For Patients

17 PATIENT COUNSELING INFORMATION Medication Guide Advise the patient to read the FDA-approved patient labeling ( Medication Guide ). Nephrogenic Systemic Fibrosis Instruct patients to inform their physician if they: have a history of kidney disease have recently received a GBCA GBCAs increase the risk for NSF in patients with impaired elimination of the drugs. To counsel patients at risk for NSF: describe the clinical manifestations of NSF describe procedures to screen for the detection of renal impairment Instruct patients to contact their physician if they develop signs or symptoms of NSF following ProHance 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. General Precautions Pregnancy: Advise a pregnant woman of the potential risk of fetal exposure to ProHance [see Use in Specific Populations ( 8.1 )] Gadolinium retention: Advise patients that gadolinium is retained for months or years in brain, bone, skin, and other organs 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 ( 5.3 )] .

This Medication Guide has been approved by the U.S. Food and Drug Administration Issued: 12/2020 COEB504 MEDICATION GUIDE PROHANCE ® (prō-ˈhan(t)s) (Gadoteridol injection) for intravenous use What is PROHANCE? PROHANCE is a prescription medicine called a gadolinium-based contrast agent (GBCA). PROHANCE, like other GBCAs, is used with a magnetic resonance imaging (MRI) scanner. An MRI exam with a GBCA, including PROHANCE, helps your doctor to see problems better than an MRI exam without a GBCA. Your doctor has reviewed your medical records and has determined that you would benefit from using a GBCA with your MRI exam. What is the most important information I should know about PROHANCE? PROHANCE contains a metal called gadolinium. Small amounts of gadolinium can stay in your body including the brain, bones, skin and other parts of your body for a long time (several months to years). It is not known how gadolinium may affect you, but so far, studies have not found harmful effects in patients with normal kidneys. Rarely, patients have reported pains, tiredness, and skin, muscle or bone ailments for a long time, but these symptoms have not been directly linked to gadolinium. There are different GBCAs that can be used for your MRI exam. The amount of gadolinium that stays in the body is different for different gadolinium medicines. Gadolinium stays in the body more after Omniscan or Optimark than after Eovist, Magnevist, or MultiHance. Gadolinium stays in the body the least after Dotarem, Gadavist, or ProHance. People who get many doses of gadolinium medicines, women who are pregnant and young children may be at increased risk from gadolinium staying in the body. Some people with kidney problems who get gadolinium medicines can develop a condition with severe thickening of the skin, muscles and other organs in the body (nephrogenic systemic fibrosis). Your healthcare provider should screen you to see how well your kidneys are working before you receive PROHANCE. Do not receive PROHANCE if you have had a severe allergic reaction to PROHANCE. Before receiving PROHANCE, tell your healthcare provider about all your medical conditions, including if you : have had any MRI procedures in the past where you received a GBCA. Your healthcare provider may ask you for more information including the dates of these MRI procedures. are pregnant or plan to become pregnant. It is not known if PROHANCE can harm your unborn baby. Talk to your healthcare provider about the possible risks to an unborn baby if a GBCA such as PROHANCE is received during pregnancy have kidney problems, diabetes, or high blood pressure have had an allergic reaction to dyes (contrast agents) including GBCAs What are the possible side effects of PROHANCE? See “What is the most important information I should know about PROHANCE?” Allergic reactions. PROHANCE can cause allergic reactions that can sometimes be serious. Your healthcare provider will monitor you closely for symptoms of an allergic reaction. The most common side effects of PROHANCE include: nausea, distortion of the sense of taste, and headache. These are not all the possible side effects of PROHANCE. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. General information about the safe and effective use of PROHANCE. Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. You can ask your healthcare provider for information about PROHANCE that is written for health professionals. What are the ingredients in PROHANCE? Active ingredient: gadoteridol Inactive ingredients: calteridol calcium, tromethamine Manufactured by: BIPSO GmbH-78224 Singen (Germany) Manufactured for: Bracco Diagnostics Inc., Monroe Township, NJ 08831 For more information, go to www.imaging.bracco.com or call 1-800-257-5181.

  • Your doctor has reviewed your medical records and has determined that you would benefit from using a GBCA with your MRI exam.
  • What is the most important information I should know about PROHANCE?
  • PROHANCE contains a metal called gadolinium. Small amounts of gadolinium can stay in your body including the brain, bones, skin and other parts of your body for a long time (several months to years).
  • It is not known how gadolinium may affect you, but so far, studies have not found harmful effects in patients with normal kidneys.
  • Rarely, patients have reported pains, tiredness, and skin, muscle or bone ailments for a long time, but these symptoms have not been directly linked to gadolinium.
  • There are different GBCAs that can be used for your MRI exam. The amount of gadolinium that stays in the body is different for different gadolinium medicines. Gadolinium stays in the body more after Omniscan or Optimark than after Eovist, Magnevist, or MultiHance. Gadolinium stays in the body the least after Dotarem, Gadavist, or ProHance.
  • People who get many doses of gadolinium medicines, women who are pregnant and young children may be at increased risk from gadolinium staying in the body.
  • Some people with kidney problems who get gadolinium medicines can develop a condition with severe thickening of the skin, muscles and other organs in the body (nephrogenic systemic fibrosis). Your healthcare provider should screen you to see how well your kidneys are working before you receive PROHANCE.
  • Do not receive PROHANCE if you have had a severe allergic reaction to PROHANCE.
    Before receiving PROHANCE, tell your healthcare provider about all your medical conditions, including if you:
  • have had any MRI procedures in the past where you received a GBCA. Your healthcare provider may ask you for more information including the dates of these MRI procedures.
  • are pregnant or plan to become pregnant. It is not known if PROHANCE can harm your unborn baby. Talk to your healthcare provider about the possible risks to an unborn baby if a GBCA such as PROHANCE is received during pregnancy
  • have kidney problems, diabetes, or high blood pressure
  • have had an allergic reaction to dyes (contrast agents) including GBCAs
  • What are the possible side effects of PROHANCE?
  • See “What is the most important information I should know about PROHANCE?”
  • Allergic reactions. PROHANCE can cause allergic reactions that can sometimes be serious. Your healthcare provider will monitor you closely for symptoms of an allergic reaction.
  • The most common side effects of PROHANCE include: nausea, distortion of the sense of taste, and headache. These are not all the possible side effects of PROHANCE. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
    General information about the safe and effective use of PROHANCE. Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. You can ask your healthcare provider for information about PROHANCE that is written for health professionals.

    Clinical Studies

    14 CLINICAL STUDIES 14.1 MRI of the CNS ProHance was evaluated in two multicenter trials of 310 evaluable patients suspected of having neurological pathology. After the administration of ProHance 0.1 mmol/kg IV, the results were similar to those described below [see Clinical Studies ( 14.2 )] . In another multicenter study of 49 evaluable adult patients with known intracranial tumor with high suspicion of having cerebral metastases, two doses of ProHance were administered. First ProHance 0.1 mmol/kg was injected followed 30 minutes later with 0.2 mmol/kg. In comparison to the 0.1 mmol/kg dose alone, the addition of the 0.2 mmol/kg dose improved visualization in 67% and improved border definition in 56% of patients. In comparison to non-contrast MRI, the number of lesions after 0.1 mmol/kg increased in 34% of patients. After ProHance 0.2 mmol/kg, this increased to 44%. Pediatric Patients ProHance was evaluated in a multicenter study of 103 patients undergoing brain or spine MRI. Among these patients, the age range was 2 to 20 years; 54 were between 2 and 12 years of age; 74% were Caucasian, 11% Black, 12% Hispanic, 2% Asian, and 2% other. ProHance was given in one single 0.1 mmol/kg dose. Repeat dosing was not studied. The results of the non-contrast and ProHance MRI scans were compared. In this database, MRI enhancement was noted in approximately 60% of the scans and additional diagnostic information in 30 to 95% of the scans. A prospectively planned study of 125 pediatric patients younger than 2 years of age retrospectively selected was performed. These patients (70 boys and 55 girls) had an age range of 1 day to 24 months old; 17 were less than 1 month of age, 40 were between 1 month and 6 months of age, 29 were between 6 months and 12 months of age, and 39 were between 12 months and 24 months of age; 56% were Caucasian, 25% Black, 5% Asian, and 14% other. ProHance was given in one single 0.1 mmol/kg dose. Repeat dosing was not studied. Three independent, blinded readers evaluated pre-contrast MRI image sets and paired pre-plus-post-contrast MRI image sets using ProHance and rated the images according to three co-primary visualization endpoints: lesion border delineation, visualization of lesion internal morphology, and lesion contrast enhancement. All three blinded readers reported improvement in the paired image sets for each of the three co-primary endpoints. 14.2 MRI of the Head and Neck ProHance was evaluated in two blinded read studies in a total of 133 adults who had an indication for head and neck extracranial or extraspinal MRI. These 133 adults (74 men, 59 women) had a mean age of 53 with a range of 19 to 76 years. Of these patients, 85% were Caucasian, 13% Black, 2% Asian, and less than 1% other. The results of the non-contrast and contrast MRI scans were compared. Approximately 75-82% of the scans were enhanced, 45-48% of the scans provided additional diagnostic information, and 8-25% of the diagnoses were changed. The relevance of the findings to disease sensitivity and specificity has not been fully evaluated.

    Geriatric Use

    8.5 Geriatric Use Of the total number of 2673 adult subjects in clinical studies of ProHance, 22% were 65 and over. No overall differences in safety were observed between these elderly subjects and the younger subjects. ProHance is known to be substantially excreted by the kidneys, and the risk of toxic reactions from ProHance may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function.

    Pediatric Use

    8.4 Pediatric Use The safety and effectiveness of ProHance have been established for use with MRI to visualize lesions with abnormal blood brain barrier or abnormal vascularity of the brain, spine, and associated tissues in pediatric patients from birth, including term neonates, to 17 years of age. Pediatric use is based on evidence of effectiveness in adults and in 103 pediatric patients 2 years of age and older, in addition to experience in 125 pediatric patients birth to less than 2 years of age that supported extrapolation from adult data [see Clinical Studies ( 14 )] . Adverse reactions in pediatric patients were similar to those reported in adults [see Adverse Reactions ( 6.1 )] . The safety and efficacy of > 0.1 mmol/kg, and sequential and/or repeat procedures have not been studied in pediatric patients [see Indications and Usage ( 1 ) and Dosage and Administration ( 2 )] . No case of NSF associated with ProHance or any other GBCA has been identified in pediatric patients ages 6 years and younger. Pharmacokinetic studies suggest that weight normalized clearance of ProHance is similar in pediatric patients and adults, including pediatric patients age younger than 2 years. Normal estimated GFR (eGFR) is around 30 mL/min/1.73m 2 at birth and increases to mature levels around 1 year of age, reflecting growth in both glomerular function and relative body surface area. Clinical studies in pediatric patients younger than 1 year of age have been conducted in patients with the following minimum eGRF; 59.37 mL/min/1.73m 2 (age just after birth to < 30 days), 118.84 mL/min/1.73m 2 (age 30 days to < 6 months), 140.44 mL/min/1.73m 2 (age 6 to 12 months).

    Pregnancy

    8.1 Pregnancy Risk Summary GBCAs cross the placenta and result in fetal exposure and gadolinium retention. The human data on the association between GBCAs and adverse fetal outcomes are limited and inconclusive (see Data) . Because of the potential risks of gadolinium to the fetus, use ProHance only if imaging is essential during pregnancy and cannot be delayed. In animal reproduction studies in rats, gadoteridol doubled the incidence of post-implantation loss at up to 16 times the recommended human dose (RHD). There were no adverse developmental effects observed in rabbits with intravenous administration of gadoteridol during organogenesis at doses up to 19 times the recommended human dose of 0.1 mmol/kg (see Data) . The estimated 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 is 15 to 20%, respectively. Data Human Data Contrast agent is visualized in the placenta and fetal tissues after maternal GBCA administration. Cohort studies and case reports on exposure to GBCAs during pregnancy have not reported a clear association between GBCAs and adverse effects in the exposed neonates. However, a retrospective cohort study, 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. 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 Gadoteridol was administered in intravenous doses of 0, 0.375, 1.5, 6.0, and 10 mmol/kg/day [0.6, 2.4, 9.7, and 16 times the recommended human dose (RHD) based on body surface area (BSA)] to female rats from gestational day (GD)6 until GD17. Gadoteridol at 10 mmol/kg/day for 12 days during gestation doubled the incidence of post-implantation loss. When rats were administered 6.0 or 10.0 mmol/kg/day for 12 days, an increase in spontaneous locomotor activity was observed in the offspring. Pregnant rabbits were administered gadoteridol in intravenous doses of 0, 0.4, 1.5, and 6 mmol/kg/day (1.3, 4.8, and 19.4 times the RHD based on BSA) from GD6 to GD18. Gadoteridol increased the incidence of spontaneous abortion and early delivery in rabbits administered 6 mmol/kg/day for 13 days during gestation.

Gadoteridol increased the incidence of spontaneous abortion and early delivery in rabbits administered 6 mmol/kg/day for 13 days during gestation. 8.2 Lactation Risk Summary There are no data on the presence of gadoteridol in human milk, the effects on the breastfed infant, or the effects on milk production. However, published lactation data on other GBCAs indicate 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 breast-fed infant. Gadoteridol is present in rat milk (see Data). The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ProHance and any potential adverse effects on the breastfed infant from ProHance or from the underlying maternal condition. Data ProHance excretion in the milk of lactating rats was evaluated at 30 minutes, 6 and 24 hours after intravenous administration of 0.1 mmol/kg of 153 Gd-gadoteridol to nursing mothers. Small amounts of compound were found in milk immediately after injection (0.14% of the ID), with the amount declining to a low level 24 hours after injection (<0.01% of the ID). 8.4 Pediatric Use The safety and effectiveness of ProHance have been established for use with MRI to visualize lesions with abnormal blood brain barrier or abnormal vascularity of the brain, spine, and associated tissues in pediatric patients from birth, including term neonates, to 17 years of age.

    Boxed Warning

    WARNING: NEPHROGENIC SYSTEMIC FIBROSIS Gadolinium-based contrast agents (GBCAs) increase the risk for NSF among patients with impaired elimination of the drugs. Avoid use of GBCAs 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 systemic fibrosis affecting the skin, muscle and internal organs. The risk for NSF appears highest among patients with: chronic, severe kidney disease (GFR less than 30 mL/min/1.73m 2 ), or acute kidney injury Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (e.g. age greater than 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing. For patients at highest risk for NSF, do not exceed the recommended ProHance dose and allow a sufficient period of time for elimination of the drug from the body prior to re-administration [see Warnings and Precautions ( 5.1 )].
