Indications

Ambelvist is a gadolinium-based contrast agent indicated in adult and pediatric patients, including term neonates, for use with magnetic resonance imaging (MRI):

Brain in white outline inside an orange circle

To detect and visualize lesions with abnormal vascularity in the central nervous system (brain, spine and associated tissues)

Person in white outline in an orange circle

To detect and visualize lesions with abnormal vascularity in the body (head and neck, thorax, abdomen, pelvis and musculoskeletal system)

Lowest approved macrocyclic gadolinium-based contrast agent (mGBCA) dose¹

Ambelvist, dosed at 0.01 mmol/kg actual body weight, delivers 0.04 mmol/Gd/kg body weight, representing 60% less gadolinium compared to mGBCAs dosed at 0.1 mmol Gd/kg¹

Ambelvist: a next-generation mGBCA with a novel tetrameric structure¹

Ambelvist is a paramagnetic tetrameric macrocyclic non-ionic complex of Gd 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 the signal intensity (brightness) of tissues¹

Relaxivity (r₁) of Gadoquatrane in Human Plasma at 37°C

Magnetic Field Strength	Relaxivity (r₁) (L/mmol/sec) per molecule*
1.5 T	47.2
3.0 T	40.8

*Gadoquatrane contains 4 chelated gadolinium ions. The per Gd relaxivity (r₁) (L/mmol/sec) is 11.8 and 10.2 at 1.5 T and 3.0 T, respectively.

Dosage and Administration

Recommended Dose

The recommended dose of Ambelvist for adult and pediatric patients, including term neonates, is 0.01 mmol/kg actual body weight (equivalent to an injection volume of 0.1 mL/kg) administered intravenously.

Clarification on Gadolinium Dose

Each molecule of gadoquatrane contains four gadolinium (Gd) ions.
Therefore, the recommended dose of 0.01 mmol/kg of gadoquatrane (administered as Ambelvist) delivers 0.04 mmol Gd/kg.

Administration and Imaging Instructions

Administer Ambelvist as an intravenous injection, manually or by compatible power injector, at a flow rate of approximately 1 mL/second to 4 mL/second, followed by a flush of 0.9% sodium chloride injection. For pediatric patients, adjust the flow rate and flush volume based on age.
Ambelvist is for intravenous use only and must not be administered intrathecally.
Use aseptic technique when preparing and administering Ambelvist.
Visually inspect Ambelvist for particulate matter and discoloration prior to administration. Do not use the solution if it is discolored, particulate matter is present, or the container appears damaged.
If solidification occurs due to cold exposure, bring Ambelvist to room temperature before use and inspect to ensure that the solution is clear and colorless to pale yellow.
Do not mix Ambelvist with other medications, and do not administer Ambelvist in the same intravenous line simultaneously with other medications because of the potential for chemical incompatibility.
Contrast MRI can begin immediately following the injection of Ambelvist.

IMPORTANT SAFETY INFORMATION AND INDICATIONS

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. Ambelvist^® is not approved for intrathecal use.

Nephrogenic Systemic Fibrosis

GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of Ambelvist^® 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 (for example, age > 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 Ambelvist^® dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration.

Contraindication and Important Information about Hypersensitivity Reactions: Ambelvist^® is contraindicated in patients with a history of severe hypersensitivity reactions to Ambelvist^®. Serious hypersensitivity reactions have occurred with GBCAs. Before Ambelvist^® 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 Ambelvist^®.

Gadolinium Retention: Gadolinium is retained for months or years in several organs. Linear GBCAs cause more retention than macrocyclic GBCAs. At equivalent doses, retention varies among the linear agents. Retention is lowest and similar among the macrocyclic GBCAs. Consequences of gadolinium retention in the brain have not been established, but they have been established in the skin and other organs in patients with impaired renal function. 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 and minimize repetitive GBCA studies, when possible.

Acute kidney Injury: In patients with chronic renal impairment, acute kidney injury sometimes requiring dialysis has been observed with the use of some GBCAs. Do not exceed the recommended dose; the risk of acute kidney injury may increase with higher than recommended doses.

Adverse Reactions: The most frequently observed adverse reactions (incidence ≥ 0.2%) were dizziness, headache, injection site reactions, nausea, vomiting, feeling hot, paresthesia, and pruritus.

INDICATIONS
