4basebio PLC has achieved a significant regulatory milestone with the initiation of Phase I/II clinical trials using its proprietary synthetic DNA technology. Following FDA Investigational New Drug (IND) approval, a global Tier 1 pharmaceutical partner has begun dosing patients with an mRNA product developed using 4basebio's opDNA® template, marking a key advancement in synthetic DNA adoption for genetic medicines.
Clinical Trial Initiation Marks Technology Validation
The Cambridge-based company announced that its pharmaceutical partner, with whom it signed a supply agreement in April 2024, has commenced patient dosing in the Phase I/II trial. While specific details of the clinical trial remain confidential due to innovator confidentiality agreements, the milestone represents a critical validation of 4basebio's synthetic DNA platform in advanced therapeutic applications.
The opDNA® template, one of four application-specific DNA templates developed by 4basebio, supports mRNA in vitro transcription (IVT) processes and offers significant advantages over incumbent plasmid DNA in terms of cost, purity, and manufacturing timelines.
Manufacturing Excellence and Regulatory Compliance
This clinical achievement follows 4basebio's receipt of Good Manufacturing Practice (GMP) certification from the UK's Medicines and Healthcare products Regulatory Agency (MHRA) for its late-phase manufacturing facility in April 2025. These accomplishments underscore the company's role as a trusted partner to the global biopharmaceutical industry, delivering high-quality synthetic DNA to power next-generation therapies.
Technology Platform Advantages
Synthetic DNA represents a fundamental shift for the life sciences sector, addressing key limitations of traditional manufacturing approaches. Unlike conventional plasmid DNA, which is constrained by lengthy manufacturing timelines and contamination risks, 4basebio's proprietary technology platform enables faster, scalable, and cell-free production of DNA templates.
This technology advancement accelerates development timelines for cell and gene therapies and vaccines while offering superior safety and consistency—two critical factors for clinical success. By removing bottlenecks in DNA supply, the platform enables researchers and drug development companies to bring transformative therapies to patients more quickly and safely, with potential applications across infectious disease, oncology, and rare genetic disorders.
Industry Momentum Building
Dr. Heikki Lanckriet, 4basebio CEO, emphasized the significance of this development: "We are delighted to have supported this leading pharmaceutical innovator in their recent IND filing and start of their patient dosing trials. This represents another major regulatory milestone for 4basebio and a clear signal of growing industry adoption of synthetic DNA in the use of cell and gene therapies and vaccines."
The CEO noted increasing momentum as a growing number of client programs advance into clinical development, suggesting broader industry adoption of synthetic DNA technologies for therapeutic applications.
