Developing an Intensified AAV Production Process to Reduce CoGs

There remains a significant need to improve adeno-associated virus (AAV) manufacturing platforms to achieve robust, high-yielding, scalable and cost-efficient processes. At Ultragenyx, we employ a producer cell line – helper-virus based infection process for AAV production which is reproducibly scalable to 2000L. To further improve on our batch process platform, we have developed a modified batch process using perfusion for AAV production to increase cell density to achieve high volumetric AAV yield. The upstream process demonstrated AAV productivity to ≥5E11 GC/mL at 250L scale, enabling delivery of an affordable AAV product suitable for clinical use.
