Sangamo Therapeutics Inc. is adding a much-needed $18 million up-front payment in a neurology-focused deal with Eli Lilly and Co. that could bring up to an additional $1.4 billion. In return, Lilly gets access to Sangamo’s neurotropic adeno-associated virus (AAV) capsid, STAC-BBB, which has shown early promise in penetrating the blood-brain barrier penetration, for one initial target with the right to add up to four more.

Spark Therapeutics Inc. has presented a proprietary adeno-associated viral (AAV) vector expressing an artificial miRNA targeting human α-synuclein (α-Syn) mRNA. Accumulation of misfolded and insoluble α-Syn causes neuronal toxicity in preclinical models and has been identified as the underlying cause of synucleinopathies.

Previous work uncovered the role of the complement system in neuroinflammation and synaptic loss in neurodegenerative disorders such as Alzheimer’s disease (AD). The third component, C3, central in all complement activation pathways, has been proposed as a potential therapeutic target in AD.
