Leucid Bio and Syenex Announce Strategic Collaboration for In Vivo CAR-T Cell Engineering
London, UK and Chicago, IL – 15 December 2025 – Leucid Bio (“Leucid” or the “Company”), a privately-held biotechnology company developing innovative Chimeric Antigen Receptor T-cell (CAR-T) therapies using its proprietary lateral CAR platform, and Syenex, an open-science genetic medicines platform company, today announced a strategic collaboration to access Syenex’s VivoCell Platform for the precise in vivo delivery of Leucid’s CAR-T assets including LEU011 for the treatment of solid tumours.
In vivo CAR-T cell engineering, which generates CAR-T cells directly within the body, addresses many limitations of conventional CAR-T cell therapies. Enabling in vivo delivery removes the need for extensive and complex ex vivo cell processing and logistics, enhancing overall clinical outcomes.
The collaboration is focused on harnessing Syenex’s VivoCell Platform to precisely deliver the LEU011 construct to T-cells in vivo when systemically administered. This represents a next-generation approach, fundamentally transforming the therapeutic profile of Leucid’s lateral CAR platform, moving toward a simpler, potentially off-the-shelf administration route. By addressing the logistical hurdles of ex vivo cell administration – this collaboration is poised to unlock the full potential of the lateral CAR-T platform, including LEU011.
