CELL CULTURE MEDIUM FOR USE IN PRODUCING GENE THERAPY PRODUCTS IN BIOREACTORS

The present disclosure describes methods and systems for use in the production of adeno-associated virus (AAV) particles, compositions, and formulations, including recombinant adeno-associated viruses (rAAV). The present disclosure presents cell culture mediums for use in producing adeno-associated viruses (AAV), such as AAV which comprise a polynucleotide encoding a payload. In certain embodiments, the cell culture medium comprises a hydrolysate mixture, L-glutamine, poloxamer 188 (e.g., 10% pluronic F-68), a lipid emulsion, and a cholesterol mixture. In certain embodiments, the production process and system use Spodoptera fmgiperda insect cells (such as Sf9 or Sf21) as viral production cells (VPCs). In certain embodiments, the production process and system use Baculo viral Expression Vectors (BEVs) and/or Baculoviral Infected Insect Cells (BIICs) in the production of rAAVs.
