About Viralgen

Viralgen is a Contract Development and Manufacturing Organization (CDMO) founded in 2017 and exists as an independently operated subsidiary of AskBio, which is wholly owned and independently operated as a subsidiary of Bayer AG. As a manufacturer of Current Good Manufacturing Practice (cGMP) certified AAV, Viralgen offers the Pro10™ based suspension manufacturing platform, a technology licensed from AskBio and developed by Chief Technical Officer Josh Grieger, PhD, and Co-Founder R. Jude Samulski, PhD, at University of North Carolina. It has been demonstrated that Pro10™ increases scalability, performance, and yield of AAV therapies¹at Viralgen and previous partners of AskBio. Located in Spain, in the Gipuzkoa Science and Technology Park, Viralgen produces AAV gene therapy treatments for pharmaceutical and biotech companies with the aim of accelerating the delivery of new treatments that may improve patients’ lives.

The company’s clinical facilities have four cGMP manufacturing suites, with 250-liter and 500-liter bioreactors. In 2020, Viralgen expanded within the Scientific Park by constructing a new building with three modules for large-scale commercial manufacturing. Each module of the state-of-the-art space includes three cGMP suites with a manufacturing capacity of >2,000 liters. The first module, which includes a suite dedicated to fully automated fill and finish operations, has received cGMP certification by the Spanish Agency for Medicines and Medical Devices (AEMPS) as part of the EMA network.

About TAAV

TAAV Biomanufacturing Solutions, SLU (TAAV), a wholly owned subsidiary of AskBio and Bayer AG, is a cGMP manufacturer of an enzymatic DNA material used for adeno associated virus (AAV) gene therapies. TAAV-manufactured 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, including plasmid backbone sequences, resulting in the production of enzymatic “no end” DNA product with what we believe is 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. For more information, go to taav.com.
