TAAV Biomanufacturing Solutions

TAAV Biomanufacturing Solutions, SLU (TAAV), a wholly owned subsidiary of Asklepios Biopharmaceuticals (AskBio) and Bayer AG, is a cGMP manufacturer of neDNA™, an enzymatic DNA material used for adeno associated virus (AAV) gene therapies.

neDNA™ is produced using a manufacturing process that eliminates the use of fermenters and bacteria, which are required in more common plasmid DNA manufacturing.

Enzymatic manufacturing removes significant levels of bacterial contaminants, resulting in the production of enzymatic DNA product with an improved safety profile for the manufacture of recombinant adeno-associated virus (rAAV) gene therapy vectors.

The TAAV manufacturing process consistently produces large amounts of neDNA using technology licensed from Touchlight IP Ltd.† in reduced times, which can be measured in days versus the months that are typical when producing plasmid DNA. TAAV was founded in 2019 and became 100% wholly owned by AskBio in 2022. Company headquarters, manufacturing facilities and labs are in San Sebastian, Spain.
