Just – Evotec Biologics launches J.CHO™ high expression system for continuous manufacturing of antibodies

  • Integration of the J.CHO High Expression System with Just – Evotec Biologics’ continuous bioprocessing platform offers high titers, high product quality and reduction of Cost of Goods Manufactured (“COGM”)

Seattle, WA, USA, 26 April 2024: Just – Evotec Biologics, the biologics segment of Evotec SE (Frankfurt Stock Exchange: EVT, MDAX/TecDAX, ISIN: DE0005664809; NASDAQ: EVO) today announced the launch of its proprietary J.CHO™ High Expression System (“J.CHO”) for antibody expression. As part of Just – Evotec Biologics’ highly-intensified continuous bioprocessing platform, J.CHO™ optimises clinical and commercial biotherapeutic production processes by providing higher productivity and high quality of complex antibody formats, including candidate antibodies, Fc-fusions, and bispecific antibodies.

Chinese hamster ovary (“CHO”) cells are a crucial part of the biologics value chain, accounting for >70% of recombinant therapeutic protein production. While CHO cells have superior capabilities in protein expression, scalability, genetic engineering, and media adaptability, the productivity varies significantly between commercially available cell lines.

J.CHO™ cell lines are engineered glutamine synthetase (“GS”) knockout cell lines adapted to grow in Just-Evotec's chemically-defined perfusion media developed for intensified, continuous manufacturing. J.CHO™ cells achieve exceptionally high antibody titers of over 4 g/L/day in perfusion, equivalent to approximately 30 g/L in fed-batch. The lead J.CHO™ host cell line was selected for high expression and excellent performance in perfusion cell culture. Alternative J.CHO™ cell lines that have been selected to provide glycan diversity to match the specific product quality requirements are also available.

Key Product Features

  1. Engineered GS knockout CHO-K1 host cell lines capable of delivering specific productivities of more than 50 pg/cell/day and growing at target densities of 60-100 million cells/mL.
  2. Transposon-based expression vectors with strong promoter sequences allowing stable integration and high expression of genes-of-interest.
  3. Proprietary chemically defined, protein-free and dual sourced perfusion cell culture media.
  4. Cell lines optimized for Just – Evotec Biologics’ upstream perfusion platform process and scalable directly from 3L to 1000L bioreactors for clinical or commercial production.

Dr Linda Zuckerman, Executive Vice President Global Head Biotherapeutics at Just – Evotec Biologics, commented: “The launch of J.CHO™, our own high-yielding cell line is a step further on our mission to dramatically expand global access to biotherapeutics. As part of Just – Evotec Biologics’ technology platform, J.CHO™ will help unlock the potential of biologics, providing elevated levels of productivity and quality while optimising clinical and commercial biotherapeutic production processes at a lower cost of goods.”

Integrated with Just – Evotec Biologics’ proprietary technology platform for biologics development and highly intensified continuous bioprocessing, J.CHO™ contributes to significantly reducing COGM. With J.CHO™, cell line development can be integrated with Just – Evotec Biologics’ proprietary J.MD™ Molecule Design suite of services allowing to produce multiple variants of a candidate antibody with improved developability characteristics. Benefits include:

  • Identification of antibody candidate variants with excellent manufacturability properties that have shown to increase titer by 3-fold compared to parental sequences.
  • More representative material produced for testing by expression in stable pools versus transient expression.
  • Time savings of up to two months by combining candidate development with cell line development.
