What is Neuraceq®

NC Brain image

A PET Scan with Neuraceq® gives physicians a “window into the brain.”

A memory or thinking test can tell a doctor if you have cognitive impairment. However, it cannot tell your doctor the cause of the problem.

An image of the brain, or a “scan,” gives your doctor a minimally invasive way to look inside the brain to see what might be causing memory and thinking problems.

The most common cause of cognitive impairment due to a neurodegenerative disease is Alzheimer’s disease (AD). In AD, sticky clumps of protein called beta(β)‐amyloid plaques build up in the brain, affecting the way the brain works.1

Neuraceq® is a radioactive tracer designed to stick to β-amyloid neuritic plaques in the brain for a short time. When used with PET scanning to create an image of your brain, Neuraceq® can reveal the presence or absence of β-amyloid plaque.

Preparing for your scan

Neuraceq® has been well-studied

Neuraceq® was studied in a large clinical trial program for this type of agent. This program was approved by the Food and Drug Administration (FDA) and European Medicines Agency (EMA).

Accurate Diagnostic Tool

It was demostrated that Neuraceq® is an accurate diagnostic tool for the estimation of β-amyloid neuritic plaque in the living brain.

Only Active for a Short Time

Neuraceq® is radioactive but only stays active in the brain for a short time. More than half of it disappear within 2 hours of being injected.

No Serious Side Effects

Clinical studies have shown no serious adverse reactions associated with Neuraceq® and an unchanged benefit/risk ratio since approval.

Neuraceq® - Indications, Use and Important Safety Information

PRODUCT INDICATIONS AND USE: NEURACEQ is a radioactive diagnostic drug indicated for positron emission tomography (PET) of the brain to estimate amyloid beta neuritic plaque density in adults with cognitive impairment for:  Evaluation of Alzheimer’s disease (AD) and other causes of cognitive decline, and selection of patients who are indicated for amyloid beta-directed therapy as described in the prescribing information of the therapeutic products.

 

NEURACEQ IMPORTANT SAFETY INFORMATION:

 

CONTRAINDICATIONS: None

WARNINGS AND PRECAUTIONS:

  • Risk for Image Misinterpretation and other Errors
    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

INDICATION

NEURACEQ® is a radioactive diagnostic drug indicated for positron emission tomography (PET) of the brain to estimate amyloid beta neuritic plaque density in adults with cognitive impairment for:

  • Selection of patients who are indicated for amyloid beta-directed therapy as described in the prescribing information of the therapeutic products

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.
