CLARISCAN: Package Insert and Label Information

CLARISCAN- gadoterate meglumine injection, solution
GE Healthcare


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:
    Chronic, severe kidney disease (GFR < 30 mL/min/1.73 m2), 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 > 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 Clariscan 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)].


Clariscan 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 (including term neonates) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity.


2.1 Dosing Guidelines

For adult and pediatric patients (including term neonates), the recommended dose of Clariscan is 0.2 mL/kg (0.1 mmol/kg) body weight administered as an intravenous bolus injection, manually or by power injector, at a flow rate of approximately 2 mL/second for adults and 1-2 mL/second for pediatric patients. Table 1 provides weight-adjusted dose volumes.

To ensure complete injection of Clariscan, the injection may be followed by normal saline flush. Contrast MRI can begin immediately following Clariscan injection.

2.2 Drug Handling

  • Visually inspect Clariscan for particulate matter prior to administration. Do not use the solution if particulate matter is present or if the container appears damaged. Clariscan should be a clear, colorless to yellow solution.
  • Do not mix with other drugs or parenteral nutrition.
  • Discard any unused portions of the drug.

Directions for Use of Clariscan (gadoterate meglumine) Injection

Glass vial:

Aseptically draw up the contrast medium into a disposable syringe and use immediately.

Plastic pre-filled syringe:

Holding the syringe vertically so the tip cap is pointed upward, aseptically remove the tip cap from the tip of the syringe and attach either a sterile, disposable needle or compatible needleless luer lock tubing set using a push- twist action. At this point, the tubing set is not attached to a patient’s intravenous connection.
  • If using a needleless luer lock tubing set, check the connection between the syringe and the tubing as the fluid flows. Ensure that the connection is successful before administration of Clariscan Injection.
  • If using a needle, hold the syringe vertically and push plunger forward until all of the air is evacuated and fluid either appears at the tip of the needle or the tubing is filled. Following the usual venous blood aspiration procedure, complete the Clariscan injection.
To ensure complete delivery of the contrast medium, the injection may be followed by a normal saline flush.
Properly dispose of the syringe and any other materials used.

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 < 30 mL/min/1.73 m2) as well as patients with acute kidney injury. The risk appears lower for patients with chronic, moderate kidney disease (GFR 30 — 59 mL/min/1.73 m2) and little, if any, for patients with chronic, mild kidney disease (GFR 60 — 89 mL/min/1.73 m2). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle, and internal organs.

Report any diagnosis of NSF following Clariscan administration to GE Healthcare at (1-800-654-0118) or FDA at (1-800-FDA-1088 or ).

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 > 60 years, diabetes mellitus or chronic hypertension), estimate the GFR through laboratory testing.

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 Clariscan 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 gadoterate meglumine, involving cardiovascular, respiratory, and/or cutaneous manifestations. Some patients experienced circulatory collapse and died. In most cases, initial symptoms occurred within minutes of gadoterate meglumine administration and resolved with prompt emergency treatment [see Adverse Reactions (6)].

  • Before Clariscan 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 Clariscan.
  • Administer Clariscan 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 Clariscan administration, observe patients for signs and symptoms of hypersensitivity reactions.

5.3 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 (e.g. 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 Omniscan (gadodiamide) and Optimark (gadoversetamide) causing greater retention than other linear agents [Eovist (gadoxetate disodium), Magnevist (gadopentetate dimeglumine), MultiHance (gadobenate dimeglumine)]. Retention is lowest and similar among the macrocyclic GBCAs [Clariscan (gadoterate meglumine), Dotarem (gadoterate meglumine), Gadavist (gadobutrol), ProHance (gadoteridol)].

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 (5.1)]. 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.

5.4 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.

5.5 Extravasation and Injection Site Reactions

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


GBCAs have been associated with a risk for NSF [see Warnings and Precautions (5.1)]. Confirmed diagnosis of NSF has not been reported in patients with a clear history of exposure to gadoterate meglumine alone.

Hypersensitivity reactions and acute kidney injury are described in other sections of the labeling [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 gadoterate meglumine exposure in 2867 patients, representing 2682 adults and 185 pediatric patients. Overall, 55% of the patients were men. In clinical trials where ethnicity was recorded, the ethnic distribution was 81% Caucasian, 11% Asian, 4% Black, and 4% others. The average age was 53 years (range from < 1 week to 97 years).

Overall, 4% of patients reported at least one adverse reaction, primarily occurring immediately or within 24 hours following gadoterate meglumine administration. Most adverse reactions were mild or moderate in intensity and transient in nature.

Table 2 lists adverse reactions that occurred in ≥ 0.2% patients who received gadoterate meglumine.

Table 2: Adverse Reactions in Clinical Trials
Reaction Rate (%)n= 2867
Nausea 0.6%
Headache 0.4%
Injection Site Pain 0.4%
Injection Site Coldness 0.2%
Rash 0.2%

Adverse reactions that occurred with a frequency < 0.2% in patients who received gadoterate meglumine include: feeling cold, feeling hot, burning sensation, somnolence, pain, dizziness, dysgeusia, blood creatinine increased, hypotension, hypertension, asthenia, fatigue, injection site reactions (inflammation, extravasation, pruritus, swelling, warmth), paresthesia, pruritus, laryngeal discomfort, pain in extremity, vomiting, anxiety and palpitations.

Adverse Reactions in Pediatric Patients

During clinical trials, 185 pediatric patients (52 aged < 24 months, 33 aged 2 – 5 years, 57 aged 6 – 11 years and 43 aged 12 – 17 years) received gadoterate meglumine. Overall, 7 pediatric patients (3.8%) reported at least one adverse reaction following gadoterate meglumine administration. The most frequently reported adverse reaction was headache (1.1%). Most adverse events were mild in intensity and transient in nature.
