4basebio and TriLink BioTechnologies Partner to Advance Leading Pharmaceutical Company’s Phase I Cell Therapy Program
- Collaboration extends existing relationship with the Tier 1 pharmaceutical customer into cell therapy programs
- End-to-end supply chain combines 4basebio's proprietary opDNA® enzymatic DNA starting material with TriLink's industry-leading GMP mRNA manufacturing capabilities and proprietary CleanCap® co-transcriptional capping technology
CAMBRIDGE, UK – 28 September, 2026 – 4basebio PLC (AIM: 4BB), a specialist in enzymatically-produced DNA for new genetic medicines, announces they will supply clinical-grade opDNA® starting material for a multi-national pharmaceutical innovator’s (“the Client”) latest cell therapy program.
Under the agreement, 4basebio will supply synthetic DNA to be used as a critical material for the Client’s upcoming Phase I clinical trial. TriLink BioTechnologies (TriLink), part of Maravai LifeSciences has been selected as the contract development and manufacturing organisation (CDMO) to manufacture the mRNA drug substance, applying its proprietary CleanCap® co-transcriptional capping technology. The agreement reflects 4basebio’s commitment and mission to provide a safer, cost-effective replacement for plasmid DNA in the development of genetic medicines.
Christine Wolosin, Chief Commercial Officer at 4basebio, added: “We're excited to continue our relationship with this leading pharmaceutical innovator as they advance new molecules into the clinic. This collaboration is a testament to the quality and consistency of our opDNA® platform, and to the strength of the partnerships we've built across the CDMO ecosystem. Working alongside TriLink – a world-class mRNA manufacturer - allows us to plug our starting material seamlessly into established manufacturing workflows, giving customers a faster, lower-risk path to the clinic without having to change how they already work with their chosen manufacturing partners.”
Chad Decker, Senior Vice President, Global Sales at TriLink commented: “TriLink is proud to be the CDMO of choice for this important cell therapy program. With our CleanCap® technology paired with 4basebio's high-purity opDNA® as starting material, we can offer this program with exceptional consistency from DNA template through finished drug substance. This is exactly the kind of end-to-end, quality-forward collaboration that accelerates programs from IND to first patient. We look forward to applying our mRNA manufacturing expertise to help bring this therapy closer to patients.”
