Vigene Biosciences Awarded Patent for improvements in the packaging efficiency of recombinantly-modified adeno-associated virus (AAV)

ROCKVILLE, Md., Feb. 24, 2020 /PRNewswire/ -- Vigene Biosciences, Inc. (Vigene), a leading biotechnology company for viral vector production and development for cell and gene therapies, announced the award of a patent from USPTO on recombinantly-modified adeno-associated virus (AAV) helper vectors that are capable of increasing the packaging efficiency of recombinantly-modified adeno-associated virus (rAAV).  Vigene's newly patented rAAV helper vectors have been further modified to replace (or augment) the promoter sequences that are natively associated with the Rep proteins encoded by such rAAV. The use of such substitute or additional promoter sequences causes increased production of recombinantly-modified adeno-associated virus in some cases 3 times to 5 times as much as that from regular Rep/Cap plasmids.  This is a key component in realizing Vigene's mission to make gene therapy affordable.

"We are pleased to have this technology available to our clients for AAV GMP production," stated Dr. Zairen Sun, Vigene's CEO.  "The ability to more efficiently package transgenes will significantly improve the yield of viral vector productions, enabling our clients to attain amounts necessary for therapeutic application more rapidly and at a lower overall cost."
