Exidavnemab is being developed as a novel disease-modifying treatment for synucleinopathies such as MSA and Parkinson’s disease. It is a monoclonal antibody (mAb) that selectively targets soluble alpha-synuclein aggregates, such as oligomers or protofibrils. By promoting the clearance of aggregated alpha-synuclein, exidavnemab may reduce the spreading and the negative effects of alpha-synuclein. Thereby, neuronal function and survival may be preserved, and disease progression ultimately slowed down, describes the company.
