FDA Issues Warning Letter to Eli Lilly and Company Regarding Imaging Compound Amyvid

On Sept. 6, 2012, the FDA issued a letter sent to Eli Lilly and Company regarding a web page for PET imaging compound Amyvid. The letter reads:

DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service
Food and Drug Administration Silver Spring, MD 20993
Josephine Secnik, MS, MBA Director, Global Regulatory Affairs– U.S. Eli Lilly and Company Lilly Corporate Center Indianapolis, Indiana 46285
RE: NDA #202008
Amyvid™ (Florbetapir F 18 Injection) for intravenous use
MA #9
Dear Ms. Secnik:
As part of its routine monitoring and surveillance program, the Office of Prescription Drug Promotion (OPDP), Division of Professional Drug Promotion (DPDP) of the U.S. Food and Drug Administration (FDA) has reviewed a webpage (AM77988) for Amyvid™ (Florbetapir F 18 Injection) (Amyvid), submitted by Eli Lilly and Company’s (Eli Lilly) under cover of Form FDA-2253. This webpage includes a misleading multi-colored image of the brain. Additionally, OPDP has been made aware that these misleading images appeared in the commercial exhibit hall of the American Academy of Neurology annual meeting held in New Orleans, Louisiana on April 23-26, 2012. OPDP has determined that the materials misbrand Amyvid in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 352(a) & (n). See 21 CFR 202.1(e)(6)(xviii).
Background
Below are the indication and summary of the most serious and common risks associated with the use of Amyvid.1 According to the INDICATIONS AND USAGE section of the FDA-approved product labeling (PI):
Amyvid is indicated for Positron Emission Tomography (PET) imaging of the brain to estimate β-amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer’s Disease (AD) and other causes of cognitive decline. A negative Amyvid scan indicates sparse to no neuritic plaques and is inconsistent with a neuropathological diagnosis of AD at the time of image acquisition; a negative scanresult reduces the likelihood that a patient’s cognitive impairment is due to AD. A positive Amyvid scan indicates moderate to frequent amyloid neuritic plaques; neuropathological examination has shown this amount of amyloid neuritic plaque is present in patients with AD, but may also be present in patients with other types of neurologic conditions as well as older people with normal cognition. Amyvid is an adjunct to other diagnostic evaluations.
1 This information is for background purposes only and does not necessarily represent the risk information that should be included in the promotional piece cited in this letter.
Limitations of Use:
• A positive Amyvid scan does not establish a diagnosis of AD or other cognitive
disorder.
• Safety and effectiveness of Amyvid have not been established for:
o Predicting development of dementia or other neurologiccondition;
o Monitoring responses to therapies.
The PI for Amyvid contains Warnings and Precautions regarding the risk of image
misinterpretation and other errors as well as the risk of radiation exposure. In addition,
according to the ADVERSE REACTIONS section of the PI, the most commonly reported
adverse reactions include headache, musculoskeletal pain, fatigue, and nausea.
Misleading Presentation
The Amyvid webpage features a multi-colored brain image. This presentation misleadingly
suggests that Amyvid PET images can be displayed, and therefore interpreted, in color in
patients with cognitive impairment who are being evaluated for Alzheimer’s Disease and
other causes of cognitive decline, when this is not the case. According to the DOSAGE AND
ADMINISTRATION section of the PI, Amyvid PET scans should be displayed and reviewed
“using a black-white scale with the maximum intensity of the scale set to the maximum
intensity of all the brain pixels.” The PI further includes several examples of black and white
scans to illustrate proper image interpretation.
While many PET images are displayed and reviewed in color, Amyvid scans, as described
above, must be displayed and reviewed using a black and white scale. Additionally, the PI
does not provide instructions for estimating β-amyloid neuritic plaque density using a color
scale with Amyvid. Therefore, use of the color PET scan image of a brain in Amyvid
promotional materials is misleading, particularly considering the warning regarding the risk for
image misinterpretation and other errors.
Conclusion and Requested Action
For the reasons discussed above, this webpage misbrands Amyvid in violation of the FD&C
Act, 21 U.S.C. 352(a) & (n). See 21 CFR 202.1(e)(6)(xviii).
