PHILADELPHIA CREAM, March 7, 2022 /PRNewswire/ — WuXi Advanced Therapies (WuXi ATU), a wholly owned subsidiary of WuXi AppTec, today announced the launch of Tetracycline Activated Self-Silent Adenovirus (TESSA™). This technology is a new state-of-the-art process for the scalable, transfection-free manufacturing of adeno-associated viruses (AAVs) at the Good Manufacturing Practices (GMP) level. Developed by OXGENE in the UKA WuXi Advanced Therapies company, TESSA™ will accelerate AAV manufacturing and dramatically reduce the manufacturing cost of cell and gene therapies, enabling global customers to deliver more accessible breakthrough therapies to patients as quickly as possible.

The AAV vector is a popular tool for delivering gene therapies in diseases such as hemophilia and Alzheimer’s disease. Efficient large-scale AAV manufacturing processes are essential to meet growing industry demands. TESSA™ vectors can address the scalability challenges of AAV production, which has important implications for expanding patient access to these new therapies.

The new data published in Nature Communication supports the benefits of this technology. He points out that in the same manufacturing volume, TESSA™ vectors produced 10 times more AAV than plasmid-based manufacturing, yielding enough material to treat ten times the number of patients.

“The TESSA™ System is a game-changer for manufacturing AAVs and advancing cell and gene therapies for the benefit of patients.” says dr. Ryan Cawood, scientific director of WuXi ATU. “By improving scalability, reducing process complexity and reducing gene therapy manufacturing costs, TESSA™ will enable our global partners to develop and deliver lifesaving gene therapies to more patients in need faster.” .

As a Contract Testing Development and Manufacturing Organization (CTDMO) operating globally, WuXi ATU’s unique business model integrates powerful testing capabilities with its therapies process development and manufacturing platforms. advances, such as TESSA™ technology for the manufacture of AAVs and stable Lenti solutions for the manufacture of lentivirals. . This allows all assay development, biosafety, viral clearance and product release testing to be performed in-house, shortening customer timelines for approval of advanced therapies.
