Abbvie Inc. has paid $130 million up front to acquire Syndesi Therapeutics SA, a company working on a new mechanism to mitigate synaptic dysfunction associated with cognitive deficits. The deal includes up to $870 million in milestone payments for Syndesi's first-in-class modulators of the synaptic vesicle protein 2A, which Abbvie said could have applications across a range of neuropsychiatric and neurodegenerative disorders, such as Alzheimer's disease and major depressive disorder.
