  • Be sure to bring a list of all the medications you are currently taking, and be ready to share your medical history.

What to expect

A Neuraceq® PET scan involves an injection into a vein in your arm and is followed by a scan of your brain. A flushing solution may be injected to help Neuraceq® move more quickly through the bloodstream.

Understanding your results

Injection

Neuraceq® injection is given through an IV (intravenous) tube.

45+ Minutes

The Neuraceq® scan can be performed 45 to 130 minutes after injection and usually lasts 15 to 20 minutes.

During the Scan

During the scan, you will lie down on a table while the PET scanner camera passes overhead.

After the Scan

After the scan, an imaging specialist will view the results, write a report, and send it to your doctor.

    NEURACEQ Risk of Image Misinterpretation and Other Errors: Image interpretation errors have been observed. [see Section 5.1 of the full prescribing information]
  • Radiation Risk
    NEURACEQ, similar to other radiopharmaceuticals, contributes to a patient's overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling to protect patients and health care workers from unintentional radiation exposure [see Dosage and Administration in the full prescribing information].

ADVERSE REACTIONS:

  • The most commonly reported adverse reactions in clinical trials were injection site pain (3.4%), injection/application site erythema (1.7%), and injection site irritation (1.1%).

USE IN SPECIFIC POPULATIONS:

  • Pregnancy : All radiopharmaceuticals, including NEURACEQ, have a potential to cause fetal harm depending on the stage of fetal development and the magnitude of the radiopharmaceutical dose. If considering NEURACEQ administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation dose from the drug and the gestational timing of exposure.
  • Lactation : Temporarily discontinue breastfeeding. A lactating woman should pump and discard breast milk for 24 hours after NEURACEQ administration.
  • Pediatric Use:  The safety and effectiveness of NEURACEQ have not been established in pediatric patients.
  • Geriatric Use: No overall differences in safety or effectiveness were observed between subjects 65 years of age and older and younger adult subjects.

OVERDOSAGE:
 In the event of administration of a radiation overdose with NEURACEQ, the absorbed organ dose to the patient should be reduced by increasing elimination of the radionuclide from the body by inducing frequent micturition. Prior to NEURACEQ administration, please read the full Prescribing Information for additional Important Safety Information.

SUSPECTED ADVERSE REACTIONS: please report to: https://www.fda.gov/safety/medwatch-fda-safety-information-and-adverse-event-reporting-program

What is NEURACEQ®?

NEURACEQ® (florbetaben F18 Injection) is a FDA approved imaging medicine used during a brain scan called positron emission tomography (PET). It helps doctors to see whether certain protein deposits, called amyloid plaques, are present in the brain.

This scan is used in adults who are experiencing memory or cognition problems to help:

  • Understand whether Alzheimer’s disease may be causing symptoms, or if another condition could be involved with cognitive decline.
  • Determine whether a person may be eligible for certain treatments that target amyloid plaques, based on the treatment’s prescribing information.
IMPORTANT FACTS
WHAT ARE SOME IMPORTANT THINGS TO KNOW ABOUT THE USE OF NEURACEQ®?
Risk of Image Misinterpretation and Other Errors

Image interpretation errors have been observed. There may be differences or errors when evaluating the presence of amyloid plaque in the brain using NEURACEQ®. Certain factors—such as significant brain shrinkage or movement during the scan—can make the images harder to read and may affect how clearly different parts of the brain can be seen.

Your specialist reads the NEURACEQ® image without taking into account your symptoms or medical history to avoid presumptions. In cases where it is difficult to tell exactly where a signal comes from in the brain, your healthcare providers may compare the NEURACEQ® scan with another type of brain image (magnetic resonance imaging or computer tomography) to better understand the findings.

Radiation Risk

NEURACEQ® uses a small amount of radiation, which adds to a person’s total lifetime exposure to radiation. Over time, higher amounts of radiation exposure may increase the risk of cancer. Health care professionals take special precautions to handle this medication safely and reduce unnecessary radiation exposure for both patients and staff. You are encouraged to drink plenty of fluids before and after the scan and to urinate often afterward.

WHO SHOULD TAKE EXTRA CARE WHEN USING NEURACEQ®?
Pregnant women

There is limited information about the use of NEURACEQ® during pregnancy. It is not known whether this scan could affect an unborn baby because studies in pregnant women and animals in reproduction have not been done. NEURACEQ® contains a small amount of radiation. All imaging medicines that use radiation may pose some risk to an unborn baby, depending on how far along the pregnancy is and how much radiation is involved.

If you are pregnant or think you might be pregnant, talk with your health care provider before having this scan. They will discuss the potential risks and benefits with you. It is important to know that all pregnancies have some natural risk. In the general population, about 2–4% of babies are born with a major birth defect, and about 15–20% of pregnancies end in miscarriage.

Breastfeeding mothers

It is not known whether NEURACEQ® passes into breast milk, how it might affect a breastfed baby or whether it could impact milk production. To reduce any possible radiation exposure to a nursing infant, mothers are advised to pump and discard breast milk for 24 hours after receiving NEURACEQ® to minimize radiation exposure. Breastfeeding can be resumed after that time. When making decisions about breastfeeding, both the benefits of breastfeeding and the mother’s medical need for the scan should be considered.

Patients under 18

NEURACEQ® has not been studied in children. Its safety and effectiveness are not known for pediatric patients.

Patients over 65

NEURACEQ® has been studied in adults aged 65 and older, including those over age 75. Studies did not show differences in safety or effectiveness between older adults and younger adults.

WHAT IF I GET TOO MUCH RADIATION?

If too much NEURACEQ® is given by mistake, your body may clear it more quickly by drinking fluids and urinating often. This helps reduce radiation exposure.

HOW WILL I RECEIVE NEURACEQ®?

There are strict laws on the use, handling and disposal of radiopharmaceutical products. NEURACEQ® is given only by trained and qualified health care providers who have specific experience working with imaging medicines that contain small amounts of radiation. These providers are licensed and approved by appropriate regulatory authorities to use these products safely.

WHAT ARE THE MOST COMMON SIDE EFFECTS OF NEURACEQ®?

The most common side effects (incidence ≥ 1%) were injection site pain, injection site redness, or irritation at the injection site.

This is not a complete report of risk information for NEURACEQ®. Talk to your healthcare provider about any side effects that concern you. You are encouraged to report negative side effects of prescription drugs to FDA: visit www.fda.gov/medwatch or call 1-800-FDA-1088 OR Lantheus Biosciences at 1-833-491-2524 OR PHV@lantheus.com.

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Risk of Image Misinterpretation and Other Errors

Image interpretation errors have been observed. Errors may occur in the estimation of brain amyloid beta neuritic plaque density during NEURACEQ® image interpretation. The use of clinical information in the interpretation of NEURACEQ® images has not been evaluated and may lead to an inaccurate assessment. Severe brain atrophy as well as motion artifacts that result in image distortion may limit the ability to distinguish gray and white matter on a NEURACEQ® scan. Perform image interpretation independently of the patient’s clinical information. For cases where there is uncertainty as to the location of cortical signal, use co-registered anatomical imaging to improve localization of signal.

Radiation Risk

NEURACEQ® contributes to a patient's overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe drug handling to protect patients and health care providers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration.

ADVERSE REACTIONS

Most common adverse reactions (incidence ≥1%) were injection site pain, injection site erythema, and injection site irritation.

USE IN SPECIFIC POPULATIONS

Lactation: Temporarily discontinue breastfeeding. A lactating woman should pump and discard breast milk for 24 hours after NEURACEQ® administration.

To report suspected adverse reactions of NEURACEQ®, contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. or Lantheus Biosciences Ltd. at 1-833-491-2524 or phv@lantheus.com.
