Therapy of Alzheimer's Disease with an antibody against oligomeric pyro-Glu-Abeta peptides
Scientists at the University of Göttingen developed a novel, proprietary antibody for the therapy and/or diagnosis of Alzheimer's Disease (AD) through the targeting of specifically pyro-Glu-Amyloid beta peptides.
Alzheimer's Disease (AD) is the main neurodegenerative disease worldwide affecting more than 29 Mill. people. By 2050 the prevalence will quadruple, by this time 1 in 85 persons worldwide will be living with AD. AD still features high growth potential and room for further innovation due to the huge worldwide growth of the number of patients and the lack of efficacious drugs. The AD market is estimated at 1,6 Mrd US$ for 2015, the main countries affected being USA, Japan and Germany.
We developed a new proprietary, monoclonal antibody against Alzheimer's Disease.
This antibody selectively targets specifically oligomeric pyro-Glu-Abeta 3-42 peptides. Intraneuronal pyro-Glu-Abeta 3-42 peptide is toxic and triggers neurodegeneration and lethal neurological deficits. In its oligomeric form pyro-Glu-Abeta peptides are the triggers of Abeta aggregation and plaque formation, thus play a key role in the development and progression of AD.
(1) Therapeutic effect: Rescue of behavioral deficits
(2) Reduction of plaque load
- Therapy of AD
- Therapy of familial AD as an orphan drug
- Companion diagnostic, diagnostic for patient recruiting and therapy efficacy test
- Diagnosis of AD as a blood ELISA test
Proof of concept (rescue of behavioral deficits) in a mouse animal model.
