FectoVIR®-AAV: The next-generation transfection reagent for large scale AAV manufacturing.

With the rapid growth of the gene therapy market, many manufacturing challenges still need to be addressed in order to efficiently produce large volumes of recombinant AAVs. Transient transfection of suspension cells is the most commonly used production platform for AAV manufacturing. Twenty years of transfection expertise has led Polyplus to the development of the next generation transfection reagent, FectoVIR®-AAV. In our presentation, we will discuss how FectoVIR®-AAV addresses the current AAV manufacturing limitations with i) increased AAV titers, ii) improved industrial transfection protocols, and iii) high quality and GMP compliance.

The number of ATMP therapeutic-based medicines for inherited genetic disorders is in constant growth, with a global 32% increasein new clinical trials in the last 4 years. ATMPs have demonstrated their success with already more than ten approved for commercialization. The success of AAV as the most promising viral vector for gene therapy is due to low immunogenicity, broad tropism and non-integrating properties. One major challenge for translation of promising research to clinical development is the manufacture of sufficient quantities of AAV. Transient transfection of suspension cells is the most commonly usedproduction platform, as it offers significant flexibility for cell and gene therapy development. However, this method presents some limitations in largescale bioreactors: inadequate transfection protocol, reduced transfection efficiency and lower productivity. To address this concern, we present data on a novel transfection reagent showing: i) increased AAV titers, ii) improved transfection protocol for large scale bioreactors and iii) reproducibility of viral titers at different production scale. The aforementioned optimizedparameters make this novel transfection reagent ideal for cell and gene therapy developers by combining the flexibility of transient transfection with scalability and speed to market.
