Appl. No.:

13/544554

Inventors:

Mary Savage - West Point PA, US
Paul Shughrue - West Chester PA, US
Abigail Wolfe - Ambler PA, US
Alexander McCampbell - Chalfont PA, US

Assignee:

MERCK - Rahway NJ

International Classification:

G01N 33/566
G01N 21/64

US Classification:

435 794, 436501

Abstract:

The invention herein is directed to a selective Aβ oligomer immunoassay capable of reliably and sensitively detecting Aβ oligomers in a biological sample of a patient. In one embodiment the inventive assay uses a pair of anti-AP oligomer antibodies, 19.3 and 82E1, to detect and quantify Aβ oligomers in a cerebrospinal fluid (CSF) sample. The inventive assay can be used to differentiate Alzheimer's disease (AD) patients from non-AD patients and/or to stratify AD patients according to the severity of their disease. The inventive assay can also be used as a target engagement assay that can measure bound Aβ oligomers as a surrogate end-point for the assessment of therapeutic efficacy and/or target engagement.

Abstract:

This invention is a selective Aβ oligomer kit and immunoassay method capable of reliably and sensitively detecting Aβ oligomers in a biological sample of a patient. In one embodiment the inventive assay uses a pair of anti-Aβ oligomer antibodies, as capture and detection antibodies, to detect and quantify Aβ oligomers. The method can be used to differentiate Alzheimer's disease (AD) patients from non-AD patients and/or to stratify AD patients according to the severity of their disease.
