KBio Announces Strategic Collaboration with Leaf Expression Systems to Enhance Development and Production of Novel Therapeutics

Collaboration to focus on new plant lines and other plant-based technologies aimed at efficient production scale-up of KBio's current and future pipeline

LONDON, Sept. 28, 2022 (GLOBE NEWSWIRE) -- KBio, a leading developer of new biological treatments derived from a plant-based production system, today announced the formation of a strategic collaboration with Leaf Expression Systems Ltd. (LES), the leading UK-based plant-made pharmaceuticals R&D company. Through this collaboration, KBio will explore how LES’ cutting-edge technologies can be applied to its existing plant-based platform to enhance current and future development and production of novel protein-based therapeutics for rare and infectious diseases.

The collaboration will support the following activities:

  • Development of new technologies to improve ongoing research activities
  • Enhance expression and production of proteins within plants
  • Development of new approaches and plant lines to increase plant-derived product yields

Patrick Doyle, CEO of KBio, commented, “At KBio, we have demonstrated our plant-based platform’s revolutionary potential to produce novel antibody and vaccine candidates with high purity at a fraction of the time and cost of current technologies. Together with LES – a leader in the expression and production of proteins in plants – we believe we can further refine and optimise our existing capabilities across our current manufacturing process, while also identifying future ways to enhance operations. This important collaboration will allow us to efficiently scale-up production of our therapeutics for global clinical trials and potential future commercial efforts.”

Simon Saxby, CEO of Leaf Expression Systems Ltd, commented, “We are delighted to be working with KBio and exploring the synergies between our businesses for the future benefit of patients worldwide. By leveraging our protein expression expertise and technologies and KBio’s differentiated plant-based platform, we are confident we can enhance the development and scalable production of novel therapeutics that will deliver significant benefits to patients in the future and are competitive in the marketplace.”
