4basebio Enters into Strategic Collaboration and Marketing Agreement with Genezen to Advance Synthetic, Cell-Free DNA Platforms for Next-Generation Viral Vector Manufacturing
CAMBRIDGE, UK - 26 August 2026 - 4basebio PLC (AIM: 4BB), a specialist in enzymatically-produced, cell-free DNA for new genetic medicines, announces that it has signed a non-exclusive Strategic Collaboration and Marketing Agreement with Genezen, a best-in-class viral vector contract development and manufacturing organization (CDMO) to provide drug developers access to 4basebio's Research Use Only, High-Quality, and GMP-grade hpDNA® technology for starting material for development and clinical programs.
Under this agreement, Genezen, an Ampersand Capital Partners portfolio company, will have access to 4basebio's synthetic DNA, specifically developed for viral vector applications. Additionally, the two parties will collaborate on commercial activities including sales and technical presentations.
By leveraging 4basebio's enzymatic, cell-free manufacturing process, customers can fully eliminate microbial contamination and the inclusion of antibiotic resistance genes, which could enhance safety, alongside accelerating development timelines from sequence to clinic.
Christine Wolosin, Chief Commercial Officer at 4basebio, added : "This partnership reflects our commitment to pairing our proprietary DNA technology with partners who share our dedication to safety, quality, and reliability. Genezen's leadership in viral vector manufacturing, combined with the growing demand we're seeing from drug developers for our DNA molecules, speaks to where this industry is heading where synthetic DNA is becoming a critical enabler of genetic medicine. 4basebio is focused on giving drug developers a manufacturing platform upon which they can confidently build their clinical programs."
Susan DeCosta, Chief Technical and Commercial Officer at Genezen, added "As the cell and gene therapy field continues to mature, developers need manufacturing solutions that not only address today's challenges, but are designed with the needs of later-stage development in mind. 4basebio's approach to synthetic DNA represents an exciting advancement in the tools available to viral vector developers. By combining innovative technologies with deep process and manufacturing expertise, we have an opportunity to help developers build more efficient, scalable manufacturing strategies from the outset - and keep the focus where it belongs: advancing therapies for patients."
