A brain-shuttled antibody targeting alpha synuclein aggregates for the treatment of synucleinopathies.

ABSTRACT: Parkinson's disease and multiple system atrophy are members of a class of devastating neurodegenerative diseases called synucleinopathies, which are characterized by the presence of alpha-synuclein (α-Syn) rich aggregates in the brains of patients. Passive immunotherapy targeting these aggregates is an attractive disease-modifying strategy, which must not only demonstrate target selectivity towards α-Syn aggregates, but also achieve appropriate brain exposure to have the desired therapeutic effect. Here we present preclinical data for SAR446159, a next-generation antibody for the treatment of synucleinopathies. SAR446159 is a bispecific antibody composed of an α-Syn-binding immunoglobulin and an engineered insulin-like growth factor receptor 1 binding single-chain variable fragment, acting
