Serum-Free Gene Therapy Cell Culture Complete Media

High-Performance, Regulatory-Friendly Viral Vector Propagation for Gene Therapy

After decades of effort, the field of gene therapy has finally reached critical mass. The FDA has now approved two adeno-associated viral vector (AAV) therapies, LUXTURNA (voretigene neparvovec-rzyl) for inherited retinal dystrophy and ZOLGENSMA (onasemnogene abeparvovec-xioi) for pediatric, inherited spinal muscular atrophy. An attenuated, genetically modified herpes simplex virus , IMLYGIC (talimogene laherparepvec), has also been approved for local oncolytic viral therapy of unresectable cutaneous, subcutaneous, and nodal melanoma lesions after postsurgical recurrence. There are now hundreds of gene and cell therapies in the FDA approval pipeline, on pace to reach as many as 10 to 20 related approvals per year by 2025.

Gene therapy relies on viral vectors like AAV or lentiviral vectors, which deliver the desirable genetic sequences into the cells of the target tissue. To produce enough material for clinical use, the viral vectors must be propagated in a host cell such as HEK293. Cultured cells and viral vector products destined for cell and gene therapy or other clinical cGMP applications must meet the highest standards for manufacturing quality, safety, performance, consistency, and efficiency. InVitria has carefully optimized its animal-free, serum-free, defined media formulations for clinically and industrially significant cultured cell lines. The OptiPEAK product line takes the guesswork out of transitioning quickly and painlessly to regulatory-friendly, serum-reduced, or serum-free cell culture for your RUO or cGMP needs.

Performance. Defined.

OptiPEAK Complete Media satisfy these cellular requirements with fully recombinant proteins that are human in sequence, fully free of animal components, and are produced in the US, using cGMP standards in an ISO 9001:2015 certified facility. Reducing or eliminating fetal bovine serum (FBS) from cell culture using OptiPEAK:

  • Reduces or eliminates the introduction of undesirable viral RNA and DNA, prion proteins, undefined antigenic molecules, as well as human or bovine cytokines and hormones.
  • Provides better, more consistent, more scalable cell growth and viral titer in culture, and more dependable manufacturing yield, product validation, and clinical safety of downstream clinical products.
  • Reduces foaming and other technical challenges in bioreactors.
  • Eliminates concerns about the fluctuating global agricultural supply chain and limitations on availability of bovine serum.

InVitria products for gene therapy applications include:

OptiPEAK HEK293t Complete Media: chemically defined and optimized to promote superior expansion kinetics of HEK293t, both in tissue culture and in scalable bioreactor formats for clinical and commercial manufacturing. This medium is ideal for cell growth as well as for regulatory-friendly production of AAV and lentiviral vectors for gene therapy applications. In development: optimization for HEK293t suspension culture.

InVitria’s Line of Animal-Free Cell Culture Components and Supplements:

  • Cellastim S recombinant human albumin to replace BSA or purified human albumin in cell culture.
  • Exbumin excipient-grade recombinant human albumin for improving stability of viral vector particles in injectable therapeutics.
  • Optiferrin recombinant human transferrin for managing iron in serum-free or serum-reduced culture applications.
  • Insulin-transferrin supplements provide supplemental rh-insulin rh-transferrin, and selenium, with or without ethanolamine and rh-albumin for serum-free or serum-reduced culture applications.
