One of the challenges of our society is to find a treatment or cure for Alzheimer's disease (AD). AD is the leading form of age-related dementia and with the increase of life expectancy worldwide, the social and economic burden from this disease will increase dramatically. It is a progressive and, in regard to clinical scores, a highly variable disease. AD pathogenesis has been associated with the accumulation, aggregation, and deposition of amyloid beta (Abeta) peptides in the brain. Hallmarks of AD are the amyloid plaques consisting of fibrillar Abeta and neurofibrillary tangles which are intracellular fibrils of hyperphosphorylated tau protein that develop later in this disease. The amyloid cascade hypothesis postulates that Abeta deposition is an initial event in the multifactorial pathogenesis and Abeta deposition may precede AD symptoms in some patients by at least 20 years. Amyloid beta therapy with active and passive immunizations against Abeta has a high possibility to be effective in removing Abeta from brain and might thus prevent the downstream pathology.
Active immunizations provide a number of benefits and considering the large number of possible patients to be treated, active immunization would be effective at a much lower price.
The Advanced Skin Vaccination EPIMMUN™ with the P.L.E.A.S.E.® device is able to create much higher immune responses than with traditional injections. So there is a high possibility to reach the necessary therapeutic level to cure Alzheimer disease.
Results will be published soon.
