Synonyms: antibody 12F4 | BIIB-054 | BIIB054
Compound class: Antibody
Comment: Cinpanemab (BIIB054) is a monoclonal antibody that binds aggregated α-synuclein [3]. Specifically it binds to the N terminus of α-synuclein. It was designed to reduce the cell-to-cell spread of toxic α-synuclein aggregates in the brains of people with Parkinson's disease, as a disease-modifying therapeutic approach to slow the rate of neuronal damage and disease progression.

Bioactivity Comments
The BIIB054 Fab binds more tightly to α-synuclein aggregates than to monomeric α-synuclein, with the affinity for aggregated α-synuclein being around 800-fold higher [3].
