Uses For Ablavar
Gadofosveset is a contrast agent. It is used in magnetic resonance angiography (MRA) to help create a clear picture of the blood vessels (arteries). The MRA scan is a special kind of diagnostic procedure. It uses magnets and computers to create images or “pictures” of the blood vessels in certain areas of the body. Gadofosveset is a gadolinium-based contrast agent (GBCA).
Gadofosveset is given by injection before MRA to help diagnose problems in the blood vessels (e.g., blockage of the arteries).
This medicine is to be used only by or under the direct supervision of a doctor.
Instruct patients receiving ABLAVAR Injection to inform their physician or healthcare provider if they:
- are pregnant or breast feeding
- have a history of allergic reaction to contrast media, a history of bronchial asthma or allergic
- respiratory disorder
- have a history of kidney and/or liver disease
- have recently received a gadolinium-based contrast agent
- have a history of heart rhythm disturbances, or cardiac disease
- are taking any prescription or over-the counter medications
GBCAs increase the risk for NSF among 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 the patients to contact their physician if they develop signs or symptoms of NSF following ABLAVAR 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.
Inform patients that they may experience:
- reactions at the injection site, such as: redness, mild and transient burning or pain or feeling of warmth or coldness
- side effects of itching or nausea

Safety and efficacy not established
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gadofosveset in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving gadofosveset.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
What is gadofosveset trisodium (ablavar)?

The following adverse reactions are discussed in greater detail in other sections of the label:
- Nephrogenic systemic fibrosis [see WARNINGS AND PRECAUTIONS]
- Hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
Clinical Studies Experience
Anaphylaxis and anaphylactoid reactions were the most common serious reactions observed following ABLAVAR injection administration [see WARNINGS AND PRECAUTIONS].
In all clinical trials evaluating ABLAVAR with MRA, a total of 1,676 (1379 patients and 297 healthy subjects) were exposed to various doses ABLAVAR. The mean age of the 1379 patients who received ABLAVAR was 63 years (range 18 to 91 years); 66% (903) were men and 34% (476) were women. In this population, there were 80% (1100) Caucasian, 8% (107) Black, 12% (159) Hispanic, 1% (7) Asian, and < 1% (6) patients of other racial or ethnic groups. Table 2 shows the most common adverse reactions ( ≥ 1%) experienced by subjects receiving ABLAVAR at a dose of 0.03 mmol/kg.
Table 2 : Common Adverse Reactions in 802 Subjects Receiving Ablavar at 0.03 mmol/kg
|Preferred Term||n (%)|
|Injection site bruising||19 (2)|
|Burning sensation||17 (2)|
|Venipuncture site bruise||17 (2)|
|Dizziness (excluding vertigo)||8 (1)|
|Feeling cold||7 (1)|
Because post-marketing 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. The profile of adverse reactions identified during the post-marketing experience outside the United States was similar to that observed during the clinical studies experience.
