Partnership to develop perfusion process for AAV production

Oct 14 2024

A £1.4m Innovate UK Transforming Medicines Manufacturing (TMM) Programme grant has been awarded to the Cell and Gene Therapy catapult (CGT Catapult), strategic partner Pharmaron Biologics (UK) Ltd and Complement Therapeutics, a developer of therapeutics for complement-mediated diseases, to develop a perfusion process that will improve gene therapy production. 

Adeno-associated virus (AAV) vectors are used in a number of approved gene therapies that target rare conditions and the aim of the two year partnership is to target higher-prevalence conditions.  Perfusion processing enables the continuous exchange of fresh culture medium and the removal of waste. This allows for AAV to be produced from a higher density of cells, over extended periods of time, reducing production costs.  

 Matthew Durdy, Chief Executive of the Cell and Gene Therapy Catapult, said: “AAV is a crucial element in many gene therapies yet there are currently no clinically approved AAV products manufactured using perfusion technologies. Working with experts at Pharmaron and Complement Therapeutics, this project offers a valuable opportunity to unlock the benefits of this manufacturing process. This aims to help make gene therapies more affordable to healthcare systems and ensure that sufficient volumes of AAV can be produced to meet an increase in demand.” 

 Derek Ellison PhD, VP Biologics Services Europe at Pharmaron Biologics (UK) Ltd, said: “While perfusion has been successfully applied to intensify production and improve manufacturability and process economics for more traditional biologics such as recombinant proteins, there are few, if any, successful applications for gene therapies. Leveraging the advanced processing and product characterisation capabilities of Pharmaron’s Liverpool site, allied with the technologies and expertise of Complement Therapeutics and the CGT Catapult, this project aims to make a major breakthrough in this area, to the benefit of patients and customers.”  

 Rafiq Hasan, Chief Executive Officer of Complement Therapeutics, said: "We are excited to collaborate with Pharmaron and the CGT Catapult on this project. Developing a perfusion process for AAV production holds significant promise for advancing our pipeline of treatments for complement-mediated diseases. This initiative not only represents a technological leap forward but also aligns with our mission to address high unmet clinical needs and ultimately improve patient outcomes.”
