This will mark the first RSNA for Guerbet since the U.S. Food and Drug Administration (FDA) approval of Dotarem® (gadoterate meglumine) Injection, a gadolinium-based contrast agent (GBCA) indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (2 years of age and older) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity.

Important Safety Information

___________________________________________________

WARNING: NEPHROGENIC SYSTEMIC FIBROSIS (NSF)

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 fibrosis affecting the skin, muscle and internal organs.

  • The risk for NSF appears highest among patients with:

o    Chronic, severe kidney disease (GFR less than 30 mL/min/1.73m2), or

o    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 (for example, age greater than 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing (see Warnings and Precautions).
  • For patients at highest risk for NSF, do not exceed the recommended Dotarem dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration (see Warnings and Precautions).

______________________________________________________

Contraindicated in patients with a history of clinically important hypersensitivity reactions to Dotarem.

The possibility of serious or life-threatening anaphylactoid/anaphylactic reactions with cardiovascular, respiratory or cutaneous manifestations, ranging from mild to severe, including death, should be considered. Monitor patients closely for need of emergency cardiorespiratory support.

In patients with chronically reduced renal function, acute kidney injury requiring dialysis has occurred with the use of GBCAs. The risk of acute kidney injury may increase with increasing dose of the contrast agent; administer the lowest dose necessary for adequate imaging. Screen all patients for renal impairment by obtaining a history and/or laboratory tests. Consider follow-up renal function assessments for patients with a history of renal dysfunction.

Ensure catheter and venous patency before the injection of Dotarem. Extravasation into tissues during Dotarem administration may result in tissue irritation.

The most common adverse reactions associated with Dotarem in clinical studies were nausea, headache, injection site pain, injection site coldness, and burning sensation.

Introduction of Dotarem to US Market

Since the introduction of Dotarem to the US market this summer, many hospitals and academic medical centers have used the product, including Cincinnati Children's Hospital Medical Center and Winthrop-University Hospital in New York. In early November, Guerbet announced that Novation, the leading health care supply chain expertise, analytics and contracting company, awarded a new technology agreement for Dotarem Injection.

Dr. Yves L'Epine, Chief Executive Officer of Guerbet, commented: “The progress and growth of Dotarem in the U.S. is important to solidly establish Guerbet in the U.S with a long term commitment to serve the radiologists community. With more than 42 million doses of Dotarem administered outside the U.S. since 1989 (1) – as well as with our other imaging enhancement products – Guerbet has a robust history of providing effective contrast agents to patients worldwide."

"We are very excited to share with RSNA attendees the increasing momentum and great interest Dotarem has received among leading U.S. radiologists and hospitals as the first and only FDA-approved macrocyclic and ionic GBCA," said Massimo Carrara, General Manager, Guerbet US.

Initial U.S. Approval: 2013

BRIEF SUMMARY OF PRESCRIBING INFORMATION

CONSULT PACKAGE INSERT FOR FULL PRESCRIBING INFORMATION

WARNING: NEPHROGENIC SYSTEMIC FIBROSIS (NSF)

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 fibrosis affecting the skin, muscle and internal organs.

  • The risk for NSF appears highest among patients with:

o    Chronic, severe kidney disease (GFR less than 30 mL/min/1.73m2), or

o    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, diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing (5.1).
  • For patients at highest risk for NSF, do not exceed the recommended DOTAREM dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration — see Warnings and Precautions (5.1).

1    INDICATIONS AND USAGE

DOTAREM is a gadolinium-based contrast agent indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (2 years of age and older) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity. (1)

4    CONTRAINDICATIONS

History of clinically important hypersensitivity reactions to DOTAREM. (4)

5    WARNINGS AND PRECAUTIONS

5.1 Nephrogenic Systemic Fibrosis

Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of GBCAs among these patients unless the diagnostic information is essential and not available with non-contrast MRI or other modalities. The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease (GFR less than 30 mL/min/1.73m2) as well as patients with acute kidney injury. The risk appears lower for patients with chronic, moderate kidney disease (GFR 30 – 59 mL/min/1.73m2) and little, if any, for patients with chronic, mild kidney disease (GFR 60 – 89 mL/min/1.73m2). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. Report any diagnosis of NSF following DOTAREM administration to Guerbet LLC (1-877-729-6679) or FDA 1-800-FDA-1088 or http://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 (e.g., age greater than 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 the degree of renal impairment at the time of exposure. Record the specific GBCA and the dose administered to a patient. For patients at highest risk for NSF, do not exceed the recommended DOTAREM dose and allow a sufficient period of time for elimination of the drug prior to re-administration. For patients receiving hemodialysis, physicians may consider the prompt initiation of hemodialysis following the administration of a GBCA in order to enhance the contrast agent’s elimination. The usefulness of hemodialysis in the prevention of NSF is unknown — see Dosage and Administration (2) and Clinical Pharmacology (12).

5.2 Hypersensitivity Reactions

Anaphylactic and anaphylactoid reactions have been reported with DOTAREM, involving cardiovascular, respiratory, and/or cutaneous manifestations. Some patients experienced circulatory collapse and died. In most cases, initial symptoms occurred within minutes of DOTAREM administration and resolved with prompt emergency treatment (see Adverse Reactions (6).

  • Before DOTAREM administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and/or allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to DOTAREM.
  • Administer DOTAREM only in situations where trained personnel and therapies are promptly available for the treatment of hypersensitivity reactions, including personnel trained in resuscitation.
  • During and following DOTAREM administration, observe patients for signs and symptoms of hypersensitivity reactions.

5.3 Acute Kidney Injury

In patients with chronically reduced renal function, acute kidney injury requiring dialysis has occurred with the use of GBCAs. The risk of acute kidney injury may increase with increasing dose of the contrast agent; administer the lowest dose necessary for adequate imaging. Screen all patients for renal impairment by obtaining a history and/or laboratory tests. Consider follow-up renal function assessments for patients with a history of renal dysfunction.

5.4 Extravasation and Injection Site Reactions

Ensure catheter and venous patency before the injection of DOTAREM. Extravasation into tissues during DOTAREM administration may result in tissue irritation — see Nonclinical Toxicology (13.2).

6 ADVERSE REACTIONS

GBCAs have been associated with a risk for NSF (see Warnings and Precautions (5.1). NSF has not been reported in patients with a clear history of exposure to DOTAREM alone. For hypersensitivity reactions and acute kidney injury see Warnings and Precautions (5.2) and (5.3).

6.1 Clinical Studies 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.

The data described below reflect DOTAREM exposure in 2813 patients, representing 2672 adults and 141 pediatric patients. Overall, 55% of the patients were men. In clinical trials where ethnicity was recorded the ethnic distribution was 74% Caucasian, 12% Asian, 4% Black, and 10% others. The average age was 53 years (range from 0.1 to 97 years).

Overall, 3.9% of patients reported at least one adverse reaction, primarily occurring immediately or several days following DOTAREM administration. Most adverse reactions were mild or moderate in severity and transient in nature.

Table 1 lists adverse reactions that occurred in greater than or equal to 0.2% patients who received DOTAREM.

Table 1: Adverse Reactions in Clinical Trials

Reaction    Rate (%) n = 2813

Nausea     0.6%

Headache     0.5%

Injection Site Pain    0.4%

Injection Site Coldness    0.2%

Burning Sensation    0.2%

Adverse reactions that occurred with a frequency less than 0.2% in patients who received DOTAREM include: feeling cold, rash, somnolence, fatigue, dizziness, vomiting, pruritus, paresthesia, dysgeusia, pain in extremity, anxiety, hypertension, palpitations, oropharyngeal discomfort, serum creatinine increased and injection site reactions, including site inflammation, extravasation, pruritus, and warmth.

Adverse Reactions in Pediatric Patients

During clinical trials, 141 pediatric patients (7 aged less than 24 months, 33 aged 2 – 5 years, 58 aged 6 – 11 years and 43 aged 12-17) received DOTAREM. Overall, 6 pediatric patients (4.3%) reported at least one adverse reaction following DOTAREM administration. The most frequently reported adverse reaction was headache (1.5%). Most adverse events were mild in severity and transient in nature, and all patients recovered without treatment.

6.2 Postmarketing Experience

The following additional adverse reactions have been identified during postmarketing use of DOTAREM. 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.

  • bradycardia, tachycardia, arrhythmia
  • hypersensitivity / anaphylactoid reactions including cardiac arrest, respiratory arrest, cyanosis, pharyngeal edema, laryngospasm, bronchospasm, angioedema, conjunctivitis, ocular hyperemia, eyelid edema, lacrimation increased, hyperhidrosis, urticaria
  • coma, convulsion, syncope, presyncope, parosmia, tremor
  • muscle contracture, muscle weakness
  • diarrhea, salivary hypersecretion
  • malaise, fever
  • NSF, in patients whose reports were confounded by the receipt of other GBCAs or in situations where receipt of other GBCAs could not be ruled out. No unconfounded cases of NSF have been reported with DOTAREM.
  • superficial phlebitis

7    DRUG INTERACTIONS

DOTAREM does not interfere with serum and plasma calcium measurements determined by colorimetric assays. Specific drug interaction studies with DOTAREM have not been conducted.

8    USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C

There are no adequate and well-controlled studies with DOTAREM conducted in pregnant women. Limited published human data on exposure to other GBCAs during pregnancy did not show adverse effects in exposed neonates. No effects on embryo fetal development were observed in rats or rabbits at doses up to 10 mmol/kg/day in rats or 3 mmol/kg/day in rabbits. The doses in rats and rabbits were respectively 16 and 10 times the recommended human dose based on body surface area. DOTAREM should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

While it is unknown if DOTAREM crosses the human placenta, other GBCAs do cross the placenta in humans and result in fetal exposure.

Reproductive and developmental toxicity studies were conducted with gadoterate meglumine in rats and rabbits. Gadoterate meglumine was administered intravenously in doses of 0, 2, 4 and 10 mmol/kg/day (or 3.2, 6.5 and 16.2 times the recommended human dose based on body surface area) to female rats for 14 days before mating throughout the mating period and until gestation day (GD) 17. Pregnant rabbits were intravenously administered gadoterate meglumine at the dose levels of 0, 1, 3 and 7 mmol/kg/day (or 3.3, 10 and 23 times the human doses based on body surface area) from GD6 to GD19. No effects on embryo fetal development were observed in rats or rabbits at doses up to 10 mmol/kg/day in rats or 3 mmol/kg/day in rabbits. Maternal toxicity was observed in rats at 10 mmol/kg/day (or 16 times the human dose based on body surface area) and in rabbits at 7 mmol/kg/day (23 times the human dose based on body surface area).

8.3 Nursing Mothers

It is not known whether DOTAREM is excreted in human milk. Limited case reports on use of GBCAs in nursing mothers indicate that 0.01 to 0.04% of the maternal gadolinium dose is excreted in human breast milk. Because many drugs are excreted in human milk, exercise caution when DOTAREM is administered to a nursing woman. Nonclinical data show that gadoterate meglumine is excreted into breast milk in very small amounts (less than 0.1% of the dose intravenously administered) and absorption via the gastrointestinal tract is poor.

8.4 Pediatric Use

The safety and efficacy of DOTAREM at a single dose of 0.1 mmol/kg have been established in pediatric patients from 2 to 17 years of age. No dosage adjustment according to age is necessary in this population — See Dosage and Administration (2.1) and Clinical Studies (14). The safety and efficacy of DOTAREM have not been established in pediatric patients below 2 years of age. GFR does not reach adult levels until 1 year of age (see Warnings and Precautions (5.1).

8.5 Geriatric Use

In clinical studies of DOTAREM, 900 patients were 65 years of age and over, and 312 patients were 75 years of age and over. No overall differences in safety or efficacy were observed between these subjects and younger subjects. In general, use of DOTAREM in elderly patients should be cautious, reflecting the greater frequency of impaired renal function and concomitant disease or other drug therapy. No age-related dosage adjustment is necessary.

8.6 Renal Impairment

No DOTAREM dosage adjustment is recommended for patients with renal impairment. Gadoterate meglumine can be removed from the body by hemodialysis [see Warnings and Precautions] (5.1) and Clinical Pharmacology (12.3).

10 OVERDOSAGE

DOTAREM administered to healthy volunteers and to patients at cumulative doses up to 0.3 mmol/kg was tolerated in a manner similar to lower doses. Adverse reactions to overdosage with DOTAREM have not been reported. Gadoterate meglumine can be removed from the body by hemodialysis (See Clinical Pharmacology (12.3).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies have not been performed to evaluate the carcinogenic potential of gadoterate meglumine.

Gadoterate meglumine did not demonstrate mutagenic potential in in vitro bacterial reverse mutation assays (Ames test) using Salmonella typhimurium, in an in vitro chromosome aberration assay in Chinese hamster ovary cells, in an in vitro gene mutation assay in Chinese hamster lung cells, nor in an in vivo mouse micronucleus assay.

No impairment of male or female fertility and reproductive performance was observed in rats after intravenous administration of gadoterate meglumine at the maximum tested dose of 10 mmol/kg/day (16 times the maximum human dose based on surface area), given during more than 9 weeks in males and more than 4 weeks in females. Sperm counts and sperm motility were not adversely affected by treatment with the drug.

13.2 Animal Toxicology and/or Pharmacology

Local intolerance reactions, including moderate irritation associated with infiltration of inflammatory cells were observed after perivenous injection in rabbits suggesting the possibility of local irritation if the contrast medium leaks around the veins in a clinical setting (see Warnings and Precautions (5.4).

17 PATIENT COUNSELING INFORMATION

17.1 Nephrogenic Systemic Fibrosis

Instruct patients to inform their healthcare provider if they:

  • have a history of kidney disease, or
