Risk For Image Misinterpretation And Other Errors
Errors may occur in the Neuraceq estimation of brain neuritic β-amyloid plaque density during image interpretation [see Clinical Studies]. Image interpretation should be performed independently of the patient's clinical information. The use of clinical information in the interpretation of Neuraceq images has not been evaluated and may lead to errors. Errors may also occur in cases with severe brain atrophy that limits the ability to distinguish gray and white matter on the Neuraceq scan. Errors may also occur due to motion artifacts that result in image distortion. Neuraceq scan results are indicative of the presence of brain neuritic β-amyloid plaques only at the time of image acquisition and a negative scan result does not preclude the development of brain neuritic β-amyloid plaques in the future.
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].
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Animal studies have not been performed to evaluate the carcinogenic potential of florbetaben.
Florbetaben did not demonstrate mutagenic potential in an in vitro bacterial mutation assay (Ames test) using five strains of Salmonella typhimurium and one strain of Escherichia coli or in an in vitro chromosomal aberration assay using human peripheral lymphocytes in the absence and presence of a metabolic activator.
No study on impairment of male or female fertility and reproductive performance was conducted in animals.
Use In Specific Populations
Pregnancy Category C: It is not known whether Neuraceq can cause fetal harm when administered to a pregnant woman or if it can affect reproduction capacity. Animal reproduction studies have not been conducted with Neuraceq. All radiopharmaceuticals, including Neuraceq, have a potential to cause fetal harm. The likelihood of fetal harm depends on the stage of fetal development and the magnitude of the radiopharmaceutical dose. Neuraceq should be given to a pregnant woman only if clearly needed. Assess pregnancy status before administering Neuraceq to a female of reproductive potential.
It is not known whether Neuraceq is excreted in human milk. Because many drugs are excreted into human milk and because of the potential for radiation exposure to nursing infants from Neuraceq, avoid use of the drug in a breastfeeding mother or have the mother temporarily interrupt breastfeeding for 24 hours ( > 10 half-lives of radioactive decay for the F 18 isotope) after exposure to Neuraceq. If breastfeeding is interrupted, the patient should pump and discard her breast milk and use alternate nutrition sources (e.g. stored breast milk or infant formula) for 24 hours after the administration of Neuraceq.
Neuraceq is not indicated for use in pediatric patients.
Of the 872 subjects in clinical studies of Neuraceq, 603 (69%) were 65 years or over, while 304 (35%) were 75 years or over. No overall differences in safety were observed between these subjects and younger subjects.
