inAAVate™ platform
Accelerating AAV success from design to GMP
OXB’s inAAVate™ platform provides a robust, standardised foundation to help partners achieve clinical and commercial milestones faster. Our end-to-end platform integrates proprietary technologies across construct design, upstream and downstream processing, analytics, and fill/finish.
Clients can access the Triple Plasmid, or Dual Plasmid System, which together with our proprietary transfection process are responsible for increasing bioreactor vg titre up to 10-fold over typical industry standards.
With the inAAVate™ platform, clients can progress from project initiation to their first GMP batch in as little as 7 months.

Frequently asked questions
In comparison to the traditional triple plasmid system, OXB’s dual plasmid system combines Rep Cap and GOI into one plasmid without impacting the DNA sequence. Together with our proprietary transfection process, the dual-plasmid system increases bioreactor titre 10-fold and can reduce the overall cost per dose.
OXB has a proven track record in supporting global regulatory filings, including 30+ successful IND submissions and 2 BLA/MAA submissions. We continuously interact with regulatory bodies and provide expert consultation on CMC dossiers, respond to regulatory questions, and provide regulatory advice on the optimum selection of assays.
OXB performs 90% of analytical assays in-house, covering 40+ analytical methods across biological activity, identity, purity, quantity and safety. We utilize 24 routine methods to test product quality on every lot.
OXB has experience with a wide range of AAV serotypes, including some of the most common natural and engineered serotypes used in cell and gene therapy. We have produced over 2,000 batches with multiple serotypes and have significant experience with novel and challenging serotypes to package and purify. Please get in touch to discuss your specific serotype.
OXB offers a number of pathways to GMP with the flexibility to meet specific client needs. These typically range from 7 to 12 months, dependent on plasmid availability, cloning requirements and the level of regulatory data needed.
Platform feasibility in just 6 weeks
For early-stage clients and those that require drug substance for in vitro or in vivo studies, we offer a cost-effective platform feasibility project, including analytics, in just 6 weeks. Test your gene of interest (GOI) in the inAAVateTM platform.
