Assay results highlight the prevalence of misfolded alpha-synuclein in Parkinson's disease (PD), Alzheimer's disease (AD), Lewy body dementia (DLB), mild cognitive impairment (MCI), and progressive supranuclear palsy (PSP)

SAN DIEGO, March 4, 2024 /PRNewswire/ -- Amprion is pleased to announce its presence at the AD/PD^™ 2024 International Conference on Alzheimer's and Parkinson's Diseases and related neurological disorders in Lisbon, Portugal on March 5-9. Amprion's αSyn seed amplification assay (αS-SAA), commercially known as the SYNTap^® Biomarker Test, has been utilized in several studies, the results of which will be shared throughout 10 posters and oral presentations during the conference.

"We look forward to sharing findings from research sites around the world related to the accurate diagnosis of neurological disorders, made possible by Amprion's αSyn seed amplification assay," said Russell Lebovitz, MD, Ph.D., Amprion CEO & Cofounder. "AD/PD^™ provides an opportunity to discuss how αS-SAA is helping to improve the diagnosis and treatment of neurodegenerative diseases such as Alzheimer's, Parkinson's, and dementia with Lewy bodies, among others. Amprion is in the process of growing its team, beginning with diagnostics service consultants, to better serve clinical needs in the United States and support researchers and biopharmaceutical companies developing life-saving drugs for patients suffering from these diseases."

Below are details of the posters and oral presentations highlighting findings related to SYNTap^®:

"The data presented on the ADNI cohort at AD/PD^™ will demonstrate the potential of using a-synuclein CSF SAA as a reliable assay for detecting co-morbid Lewy Body pathology, as well as its ability to identify this often-elusive co-pathology," said Mike Weiner, MD, and principal investigator for the Alzheimer's Disease Neuroimaging Initiative. "We believe the results will have profound implications for improving the accuracy of diagnosis, ultimately enabling the development of precision medicines for these complex neurodegenerative diseases."

About SYNTap^®:

Amprion's SYNTap Biomarker Test is a first-in-class-qualitative Laboratory Developed Test (LDT) and the only seed amplification assay available to aid the diagnosis of synucleinopathies such as Parkinson's Disease (PD), Lewy Body Dementia (LBD/DLB), and Alzheimer's Disease (AD) with Lewy Body variant. The U.S. Food and Drug Administration (FDA) granted Amprion a Breakthrough Device Designation in 2019 for use of the test as an aid in the diagnosis of PD. SYNTap became commercially available in 2021.

About Amprion:
Amprion is a global leader in the advancement of neurodegenerative disorder diagnosis through seed amplification testing. As the global population ages, Amprion aims to accelerate precision medicine for neurodegenerative disorders by helping biopharma partners identify new drug candidates and underlying pathologies. The amplification testing methodology was originally developed by Claudio Soto, PhD, Amprion's Co- Founder and Professor at The University of Texas Health Science Center at Houston and has been further enhanced and validated by Amprion's in-house scientific team. Amprion currently holds multiple U.S. and International patents for SAA methodology and strives to launch more biomarker tests to detect a wide range of early-stage neurodegenerative disorders.
