PET Neuroimaging is broadly expanding, revealing new insights into pathophysiology and providing important biomarker data for diagnosing patients and in therapeutic clinical trials
BERLIN (PRWEB) July 29, 2022
Life Molecular Imaging (LMI) announces today that new research results on its approved and investigational positron emission tomography (PET) neuroimaging tracers will be presented at the Alzheimer’s Imaging Consortium (AIC) meeting and the Alzheimer’s Association International Conference (AAIC) in San Diego (July 30 – August 4, 2022), the biggest and most influential international meeting dedicated to advancing dementia science.
The contributions cover twelve (12) presentations demonstrating the utility of its approved compound Neuraceq® (florbetaben F18 injection), thirteen (13) presentations supporting the potential of its investigational tau tracer 18F-PI-2620 and one (1) presentation highlighting first-in-human data from its investigational neuroinflammation imaging tracer 18F-DED.
LMI is also proud to be contributing with The Amyloid imaging to Prevent Alzheimer’s Disease (AMYPAD) initiative to the AAIC program. A virtual featured research session entitled “Progressing the clinical and technical value of amyloid PET in dementia – the AMYPAD experience” will be held on August 1st.
LMI in conjunction with Clario will host a reception and presentations of tau PET imaging, quantification and use in clinical trials featuring Dr. Victor Villemagne.
“We are impressed by the data that research groups around the world have collected over the last year,” said Dr. Andrew Stephens, MD, PhD, CMO of Life Molecular Imaging. “PET Neuroimaging is broadly expanding, revealing new insights into pathophysiology and providing important biomarker data for diagnosing patients and in therapeutic clinical trials.”

About Neuraceq® (florbetaben 18F)
Neuraceq® is a radioactive diagnostic agent indicated for Positron Emission Tomography (PET) imaging of the brain to estimate beta 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 Neuraceq® scan indicates sparse to no amyloid neuritic plaques and is inconsistent with a neuropathological diagnosis of AD at the time of image acquisition; a negative scan result reduces the likelihood that a patient’s cognitive impairment is due to AD. A positive Neuraceq® 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. Neuraceq® is an adjunct to other diagnostic evaluations.
Limitations of Use
- A positive Neuraceq® scan does not establish the diagnosis of AD or any other cognitive disorder.
- Safety and effectiveness of Neuraceq® have not been established for (i) predicting development of dementia or other neurologic conditions and (ii) monitoring responses to therapies.
Important Safety Information
Risk for Image Interpretation and Other Errors
Neuraceq® can be used to estimate the density of beta-amyloid neuritic plaque deposition in the brain. Neuraceq® is an adjunct to other diagnostic evaluations. Neuraceq® images should be interpreted independent of a patient’s clinical information. Physicians should receive training prior to interpretation of Neuraceq® images. Following training, image reading errors (especially false positives) may still occur. Additional interpretation errors may occur due to, but not limited to, motion artifacts or extensive brain atrophy.
Administration of Neuraceq®, like 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. It is important to ensure safe handling to protect patients and health care workers from unintentional radiation exposure.
Most Common Adverse Reactions
In clinical trials, the most frequently observed adverse drug reactions in 872 subjects with 1090 Neuraceq® administrations were injection/application site erythema (1.7%), injection site irritation (1.1%), and injection site pain (3.4%).
Tau deposits, in conjunction with beta-amyloid plaques, represent the other pathological hallmark of Alzheimer’s disease, with tau deposits further playing an important role in other neurodegenerative diseases. PI-2620 is binding to 3R/4R and 4R tau deposits and is a next generation 18F-labeled investigational PET tracer with favourable properties and imaging characteristics. It was discovered in a research collaboration between Life Molecular Imaging and AC Immune, a Swiss-based clinical stage biopharmaceutical company. Life Molecular Imaging has the exclusive, world-wide license for research, development and commercialization of tau PET tracers generated within the discovery program.
Neuroinflammation represents a key pathologic mechanism in many neurodegenerative diseases, including AD, movement disorders and multiple sclerosis. In the brain it can be mediated by activated astrocytes (astrogliosis), which show increased activity of the enzyme monoamine oxidase B (MAO-B). The PET tracer [18F]DED is a deuterated deprenyl derivative that was designed to preferentially bind to areas with increased MAO-B activity.
