Sunovion Pharmaceuticals Inc. and Afraxis, Inc. Announce Novel Drug Discovery Partnership

Partnership to Leverage Innovative Dendritic Spine Analysis and Technology to Find, Distinguish and Expedite Discovery of CNS Treatments

MARLBOROUGH, Mass. & SAN DIEGO--()--Sunovion Pharmaceuticals Inc. (Sunovion) and Afraxis, Inc. today announced that they have signed a partnership agreement to utilize the unique Enhanced Spine Platform (ESP) developed by Afraxis, Inc. to accelerate Sunovion’s preclinical central nervous system (CNS) drug discovery process. The use of this proprietary platform will allow Sunovion to identify novel CNS compounds that are potentially superior to existing treatments. While the full financial terms have not been disclosed, Afraxis will be eligible for certain milestone payments for each compound through phase 2 clinical trial initiation.

“Our partnership with Afraxis is one of several ways that Sunovion Discovery is taking a fresh approach to CNS drug discovery using systems biology as a fundamental strategy,” said Tom Large, senior vice president of discovery research at Sunovion. “A key goal of the partnership is to use ESP to guide the optimization of clinical drugs for a range of complex and often devastating psychiatric and neurological disorders.”

Dendritic spines are small protrusions on neuronal dendrites; they receive and store information from synapses and transmit that information to the neuronal cell body. Detailed analysis of dendritic spine morphology across distributed brain regions yields reliable disease spine "signatures" that can be used to screen for drug candidates that correct the disease-specific spine abnormalities. The technology behind the Afraxis ESP platform uses well-accepted dendritic spine measurement methods to evaluate spine morphology at rates of greater than a half million spines per month. The resulting information is invaluable and time-saving when making assessments of a molecule’s novel pharmacology and efficacy during preclinical testing.

“The scope of this collaboration with Sunovion envisions running up to one thousand compounds through our proprietary platform,” said Carmine Stengone, chief executive officer of Afraxis, Inc. “This collaboration offers further validation of the Afraxis ESP technology, and we feel the combination of Sunovion and Afraxis efforts will increase the odds of finding potential treatments in areas of high unmet medical need.”

About Afraxis, Inc.

Afraxis, Inc. is a San Diego-based drug discovery platform company recently spun-out of Afraxis Holdings. The company is part of a growing wave of innovative neuroscience that applies cutting-edge technical and computational approaches to fundamental issues in brain science that promise to generate new insights into CNS diseases. Afraxis develops and uses high content central nervous system (CNS) pharmaceutical screening technologies to evaluate preclinical efficacy for potential treatments for neurological and psychiatric disorders. Afraxis developed the Enhanced Spine Platform (ESP) Technology platform, which quantifies the morphology and maturity of synaptic dendritic spines that are fundamental to information processing by neural synapses in the brain. Abnormal dendritic spine quantity and morphology have been associated with numerous CNS disorders, including schizophrenia, Alzheimer’s disease, Fragile X syndrome and autism. Afraxis has a strategic alliance with PsychoGenics to offer its ESP Technology as part of PsychoGenics’ comprehensive testing capabilities and drug discovery science.
