There is no known cure for Alzheimer’s disease, a brain disorder that severely affects memory, thinking, learning, and organizing skills. It eventually decreases a person’s ability to carry out simple, daily activities. It is predicted that over 14 million Americans will develop Alzheimer’s without effective treatment options. Mild cognitive impairment (MCI) is a stage prior to Alzheimer’s when memory problems become noticeable. A patient’s ability to function and live independently remain intact as the brain compensates for disease-related changes. Disease symptoms worsen over a period that may progress over 10 years. In some people, MCI can hold steady at this stage. However, people with MCI are at high risk for progressing to dementia. Alzheimer’s disease is the most common form of dementia.
MCI is associated with neurological cell death in the hippocampus. The technology from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), describes that direct administration of an adenovirus carrying the Carboxypeptidase E (CPE) gene to the hippocampus results in overexpression of the CPE protein in an experimental mouse model of AD. CPE protein overexpression averts neurological cell death in the hippocampus. Treated mice do not develop memory impairment. This technology was effective in mice with normal expression of brain-derived neurotrophic factor (BNDF). It may be applicable to a wider range of patients, including those with BNDF deficiency and no deficiency of BNDF expression. Further, this technology may provide for a combination therapy with CPE and BNDF to treat AD.
This technology protects neurons prior to the appearance of cell damage due to accumulation of intracellular tau-containing neurofibrillary tangles and extracellular β-amyloid (Aβ) deposits in the brain.
The use of CPE as an early intervention in the initial diagnosis of MCI may stabilize the neurological condition of patients and avoid progression of AD in a large population of aging patients.
The NICHD technology is available for commercial licensing to develop as a therapy for MCI or AD. There is also opportunity for preclinical co-development of the technology with the NICHD laboratory of Dr. Peng Loh.
