Bayer Schering Pharma to develop new imaging compounds for detection of Neurodegenerative Diseases Berlin - Bayer Schering Pharma AG has signed a license and option agreement with Taisho Pharmaceutical Co., Ltd., Nihon Nohyaku Co., Ltd., and the National Institute of Radiological Sciences (NIRS), Japan, to develop novel imaging compounds for the detection of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and other disorders also associated with neuroinflammation such as multiple sclerosis. "We are convinced that innovations in molecular imaging have the potential to fundamentally improve the diagnosis of neurodegenerative disorders, particularly Alzheimer's disease. Bayer Schering Pharma is already pursuing the development of tracers targeting amyloid plaques, a hallmark of this disease. Imaging of neuroinflammation as another important pathology will excellently complement these activities," said Dr. Hans Maier, Head of Business Unit Diagnostic Imaging at Bayer Schering Pharma. "This agreement underscores our commitment to Alzheimer patients by developing innovative diagnostic methods for the early detection of the disease." Taisho Pharmaceutical Co., Ltd., Nihon Nohyaku Co., Ltd. and the National Institute of Radiological Sciences (NIRS) jointly own patent rights for a compound class that may be applied for various non-invasive imaging technologies, such as positron emission tomography (PET) scanning. Under the terms of the agreement Bayer Schering Pharma receives worldwide exclusive rights to develop and market the respective products for use with PET scanning technology. Worldwide representative epidemiological surveys estimate that 24.3 million people suffer from dementia today with about 4.6 million new cases occurring every year.

Global prevalence of dementia: a Delphi consensus study. Lancet 2005; 366:2112-17). Bayer Schering Pharma AG is a worldwide leading specialty pharmaceutical company.
