ImaginAb Executes New License and Supply Agreement for CD8 ImmunoPET Technology with Leucid Bio

April 12, 2023

ImaginAb Inc., a global biotechnology company developing 89Zr crefmirlimab berdoxam (CD8 ImmunoPET) imaging agent and radiopharmaceutical therapies (RPT), is pleased to announce the execution of a new non-exclusive License and Supply Agreement with Leucid Bio (Leucid), a biotech company pursuing a differentiated approach to develop next generation Chimeric Antigen Receptor T-cell (CAR-T) therapies using the Company’s proprietary Lateral CAR Platform.

Under the terms of the agreement, ImaginAb will license and supply clinical doses of ImaginAb’s investigational CD8 ImmunoPET tracer, 89Zr crefmirlimab berdoxam, to Leucid for use in its basket study in solid tumors, with LEU011 targeting NKG2DL, Autologous CAR T-cells.

Ian Wilson, Chief Executive Officer of ImaginAb, said: “We are delighted that Leucid Bio will use our investigational CD8 ImmunoPET for the first time in conjunction with CAR-T therapies. This agreement with Leucid Bio is an opportunity for ImaginAb to continue expanding our partnerships and showcases the increasing adoption of our CD8 ImmunoPET technology.”

Artin Moussavi, Chief Business Officer of Leucid Bio, commented: “This is an exciting partnership for Leucid as this cutting edge technology will provide evidence of the biodistribution of LEU011 CAR T-cells. This will be the first time this technology will be used in a solid tumor CAR-T clinical setting allowing Leucid to generate data that demonstrates the tracking of LEU011 to tumor sites in the first phase of the trial. This data would validate, in humans, the significant improvements already demonstrated with LEU011 in preclinical studies.”

About CD8 ImmunoPET™ (89Zr crefmirlimab berdoxam)

An 89Zr-labeled minibody that has been designed to bind to the CD8 receptor on human T cells for quantitative, non-invasive PET imaging. This method is currently being researched to determine whether it may be used to diagnose the immune status of a patient, to measure the efficacy of immunotherapies, and to predict patient outcomes.
