AbbVie, a global biopharmaceutical company, and Voyager Therapeutics, Inc., a clinical-stage gene therapy company focused on developing life-changing treatments for severe neurological diseases, today announced an exclusive, global strategic collaboration and option agreement to develop and commercialize vectorized antibodies directed at pathological species of alpha-synuclein for the potential treatment of Parkinson's disease and other diseases (synucleinopathies) characterized by the abnormal accumulation of misfolded alpha-synuclein protein.
The delivery of sufficient quantities of antibodies across the blood-brain barrier is one of the major limitations of current biologic therapies for neurodegenerative diseases that require frequent systemic injections with large amounts of antibodies. Voyager's vectorized antibody platform and approach aims to circumvent this limitation by delivering, with a potential, one-time intravenous administration, the genes that encode for the production of therapeutic antibodies utilizing Voyager's blood-brain barrier penetrant adeno-associated virus (AAV) capsids. This approach could result in the potential for higher levels of therapeutic antibodies in the brain compared with current systemic administration of antibodies.
"The expansion of AbbVie's partnership with Voyager represents the potential we see in the ability of its vectorized antibody platform to surpass the blood-brain barrier and more effectively deliver biologic therapies," said Jim Summers, Ph.D., vice president, discovery neuroscience research, AbbVie. "We are hopeful that Voyager's technology will enable further development of transformative treatments for patients with neurodegenerative diseases."
"Our scientific platform allows us to develop unique AAV gene therapies that are designed to knock down disease-causing gene expression, increase the expression of missing proteins, or enable the expression of therapeutic antibodies through vectorization," said Andre Turenne, president and chief executive officer of Voyager Therapeutics. "We are excited to expand our efforts towards pathological species of alpha-synuclein given its role in the progression of disease, and AbbVie is the ideal partner to advance this new target and therapeutic modality."
Parkinson's disease is the second most common neurodegenerative disorder worldwide. A hallmark of Parkinson's disease is the accumulation of misfolded alpha-synuclein that can eventually lead to the formation of protein deposits and progressive neurodegeneration. Approaches to interfere with this process could potentially delay the progression of Parkinson's disease and other synucleinopathies including Lewy Body Dementia and multiple system atrophy.
