Alzheimer's drug lecanemab hailed as momentous breakthrough

By James Gallagher
Health and science correspondent

The first drug to slow the destruction of the brain in Alzheimer's has been heralded as momentous.

The research breakthrough ends decades of failure and shows a new era of drugs to treat Alzheimer's - the most common form of dementia - is possible.

Yet the medicine, lecanemab, has only a small effect and its impact on people's daily lives is debated.

And the drug works in the early stages of the disease, so most would miss out without a revolution in spotting it.

Lecanemab attacks the sticky gunge - called beta amyloid - that builds up in the brains of people with Alzheimer's.

For a medical field littered with duds, despair and disappointment, some see these trial results as a triumphant turning point.

Alzheimer's Research UK said the findings were "momentous"......


Navidea Biopharmaceuticals’ NAV4694 β-Amyloid Imaging Agent to Be Used in Alzheimer’s Disease Studies by Australian Imaging, Biomarker & Lifestyle Flagship Study of Ageing (AIBL)

Leading Neurodegenerative Disease and Imaging Research Consortium to Convert to NAV4694 from “Gold Standard” 11C-labeled Pittsburgh Compound-B (PiB)

DUBLIN, Ohio--(BUSINESS WIRE)-- Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that the Australian Imaging, Biomarker & Lifestyle Flagship Study of Ageing (AIBL) plans to switch to using Navidea’s Fluorine-18 labeled β-amyloid imaging candidate, NAV4694, from 11C-labeled Pittsburgh Compound-B (PiB) for its comprehensive research initiative in Alzheimer’s disease and Mild Cognitive Impairment. Dr. Christopher C. Rowe, MD FRACP, Director of the Department of Nuclear Medicine and Centre for PET at Austin Health, Melbourne, Australia, announced the changeover to NAV4694 at the World Wide Alzheimer's Disease Neuroimaging Initiative meeting in Boston, MA.

AIBL, a globally renowned, multi-disciplinary effort to investigate factors impacting the development of Alzheimer’s disease across Australia, has previously employed the widely-recognized PiB compound in its research. PiB is the PET imaging agent prototype for β-amyloid detection, and remains an accepted benchmark standard for studies investigating Alzheimer’s disease and differential diagnoses of dementia. Recently published results from a head-to-head study funded by AstraZeneca that directly compared PiB to NAV4694 demonstrated that NAV4694 displayed imaging characteristics nearly identical to those of PiB.1

“Recent updates to appropriate use criteria allow for earlier diagnosis and therapeutic intervention in the diagnosis of probable Alzheimer’s disease, and we believe β-amyloid PET imaging will play an increasingly important role for clinicians investigating this disease,” said Dr. Rowe, lead author on the head-to-head study. “As the accepted benchmark β-amyloid imaging agent, PiB has an excellent performance profile, but issues around timing, logistics and costs make its routine use challenging. A β-amyloid imaging agent that is accessible and affordable and that can be reliably interpreted in a variety of clinical settings would be most pragmatic. Our studies with NAV4694 show that it mirrors the performance of PiB, and that we can therefore confidently make this changeover and begin using NAV4694 in our research.”

“The team at AIBL is recognized as a world leader in neurodegenerative disease and imaging diagnostics, and we are honored that they have selected NAV4694 as a β-amyloid standard for their research,” said Thomas H. Tulip, PhD, President and Chief Business Officer of Navidea. “We are pleased to support AIBL’s work in advancing research and knowledge about the development and diagnosis of Alzheimer’s disease, with the mutual goal of providing physicians with an improved diagnostic tool having outstanding performance characteristics that can aid in the diagnosis of Alzheimer's disease and other forms of neurodegenerative dementia.”

About NAV4694

NAV4694 is a Fluorine-18 labeled precision radiopharmaceutical candidate intended for use in Positron Emission Tomography (PET) imaging and evaluation of patients with signs or symptoms of cognitive impairment such as Alzheimer’s disease (AD). NAV4694 binds to β-amyloid deposits in the brain that can then be imaged in scans. β-amyloid plaque pathology is widely used in the diagnosis of AD. The ability of NAV4694 imaging to display amyloid plaque pathology may enable earlier identification of AD and improve monitoring of disease progression and interpretation of brain scan images. Navidea has an ongoing NAV4694 Phase 2b trial in Mild Cognitive Impairment and a Phase 3 program for NAV4694 in AD.
