We are a clinical-stage biotechnology company developing therapies for neurodegenerative diseases, with a focus on areas of high unmet medical need. Our work is informed by advances in disease biology, including the roles of misfolded or deficient proteins, lysosomal dysfunction, and immune and neuronal pathway disruption.

Our objective is to develop product candidates that address disease through targeted mechanisms, such as removing pathogenic proteins, replacing deficient proteins, and restoring normal cellular function. We are advancing a portfolio of programs focused on genetically validated targets, supported by our expertise in drug development, protein engineering, and antibody discovery.
