Uses

1 INDICATIONS AND USAGE AMYVID is 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 Selection of patients who are indicated for amyloid beta-directed therapy as described in the prescribing information of the therapeutic products AMYVID 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 Selection of patients who are indicated for amyloid beta-directed therapy as described in the prescribing information of t...

Dosage

2 DOSAGE AND ADMINISTRATION The recommended amount of radioactivity is 370 MBq (10 mCi) administered as a single intravenous bolus in a total volume of up to 10 mL. ( 2.2 ) Follow the injection with an intravenous flush of approximately 10 mL of 0.9% sodium chloride injection. ( 2.2 ) Obtain 10-minute PET images starting approximately 30 minutes to 50 minutes after drug administration. ( 2.3 ) See full prescribing information for image interpretation and radiation dosimetry. ( 2.4 , 2.5 ) 2.1 Radiation Safety - Drug Handling Handle AMYVID with appropriate safety measures to minimize radiation exposure during administration [see Warnings and Precautions ( 5.2 )] . Use waterproof gloves and effective radiation shielding, including syringe shields when handling and administering AMYVID.

Side Effects

6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥ 0.4%) were headache, musculoskeletal pain, increased blood pressure, nausea, fatigue, injection site reaction, anxiety, back pain, claustrophobia, dizziness, feeling cold, insomnia, and neck pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-545-5979 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Warnings

5 WARNINGS AND PRECAUTIONS Risk of Image Misinterpretation and Other Errors: Image interpretation errors have been observed. ( 5.1 ) Radiation Risk: AMYVID contributes to a patient's long-term cumulative radiation exposure. 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. ( 2.1 , 2.2 , 5.2 ) 5.1 Risk of Image Misinterpretation and Other Errors Errors may occur in the estimation of brain amyloid beta neuritic plaque density during AMYVID image interpretation [see Clinical Studies ( 14 )]. The use of clinical information in the interpretation of AMYVID images has not been evaluated and may lead to an inaccurate assessment. 4 CONTRAINDICATIONS None. None ( 4 )

Pregnancy

8.1 Pregnancy Risk Summary There are no available data on AMYVID use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with florbetapir F 18 to evaluate its effect on female reproduction and embryo-fetal development. All radiopharmaceuticals, including AMYVID, have the potential to cause fetal harm depending on the stage of fetal development and the magnitude of the radiation dose.
