China's original drug for treating alzheimer's disease, phase 971, officially went on sale in the country on DEC 29, 2019.
This drug is the first Chinese and international new drug for alzheimer's disease treatment targeting the brain-gut axis. Behind the logic of its development is a new understanding of the pathogenesis of alzheimer's disease. The theory behind most of the new alzheimer's drug trials, backed up by five drugs previously on the market, is that beta-amyloid deposits in the brain trigger inflammation that damages neurons and leads to alzheimer's. However, clinical trials of drugs developed to target beta-amyloid showed that their clinical efficacy was not significant.
The team has come up with a new understanding of the pathogenesis of alzheimer's disease: neuroinflammation caused by intestinal flora disorders is an important pathogenesis of alzheimer's disease.
