Lonza, one of the world’s largest contract development and
manufacturing organizations (CDMOs), today announced the launch of TheraPEAK
® AmpliCell
®
Cytokines and TheraPEAK
® 293-GT
® Medium to expand its GMP solutions for cell and gene therapy.
Cytokines represent a critical component in cell therapy manufacturing, supporting the expansion and
maintenance of living cells. TheraPEAK
® AmpliCell
® Cytokines enable the reliable expansion,
activation, and differentiation of immune cells. Produced in a mammalian expression system and
engineered for high biological activity, these cytokines feature proper folding and glycosylation,
delivering native-like structure and function that bacterial systems cannot match. This ensures superior
biological relevance, batch-to-batch consistency, and greater predictability in sensitive and
translational applications, both in research and GMP set-ups.
TheraPEAK
® 293-GT
® Medium is a chemically defined, animal–origin–free system optimized for
adeno-associated virus (AAV) production in suspension HEK293 cells, providing a reliable, scalable
option for advancing gene therapy programs. Unlike off-the-shelf viral production kits that may lack
flexibility, the 293-GT
® System (growth medium plus supplement) is a drop-in-ready solution
engineered to integrate seamlessly with existing workflows. The media is compatible with
commercially available transfection reagents and AAV enhancers, delivers strong AAV titers, and
supports high full-to-empty capsid ratios.
TheraPEAK
® Products have been used in FDA-approved therapies and more than 130 clinical trials
across the globe. The newly-added solutions provide researchers and manufacturers with
high-performance, scalable, and regulatory-ready solutions that streamline cell and gene therapy
workflows from discovery through clinical development.
Mike Goetter, Head of Bioscience, Specialized Modalities, Lonza, said: “The introduction of AmpliCell
®
Cytokines and the 293-GT
® Medium to our TheraPEAK
® Range greatly enhances our offering for cell and gene therapy customers, providing them with reliable solutions to support their drug development
efforts.”
